This study investigated the Pharmacokinetics of ciprofloxacin alone or with diclofenac sodium in adult Japanese quails. The quails divided into two groups, the first group was dosed intraperitoneally with 50 mg/kg of ciprofloxacin, the second group was injected by 50 mg/kg of ciprofloxacin intraperitoneally then directly injected intraperitoneally by diclofenac sodium at a dosage of 5 mg/kg. Plasma concentrations of ciprofloxacin were determined by the spectrophotometer at wavelength 290 nm. Co-admiration of ciprofloxacin with diclofenac lead to appearing ciprofloxacin in plasma at 12.02, 6.4, 5.3, 3.30, 1.36, 0.60 μg/ml in the periods of 0.25, 0.50, 1, 2, 4 and 8 hours post-injection. A significantly increased in the concentration of ciprofloxacin at times of 0.25, 0.50, 1, and 2 hours post-injection and appeared at a concentration of 6.96, 3.09, 2.2, and 0.72 μg/ml. The pharmacokinetics of ciprofloxacin when given with diclofenac sodium was represented by 91% decrease in elimination constant rate, 53% decrease in elimination half-life t1/2, 64% decrease in volume of distribution to steady-state, 22% decrease in clearance, 28% increase area under curve, 41% decrease in area under moment curve, 53% decrease in mean residence time and 37% increase in maximum plasma concentration. Our study concludes that co-administration of ciprofloxacin with diclofenac sodium lead to alteration in some pharmacokinetic data of ciprofloxacin like effect on the plasma concentration and volume of distribution and clearance. This effect must be considered when therapy by ciprofloxacin with diclofenac, the co-administration of diclofenac with ciprofloxacin decrease the elimination of ciprofloxacin

Ear mange is an annoying problem for all animal breeders including rabbit's breeders. This study aimed to compare the efficacy of moxidectin and 10% propolis ointment on rabbits infested with Psoroptes cuniculi with especial reference to some related biochemical parameters diagnostic and prognostic value. For this purpose, a total of thirty-two rabbits: 8 non-infested rabbits (control group (CG) and 24 naturally infested rabbits were used. Infested rabbits were equally divided into three groups: 1st group remained without treatment (diseased group (DG)), 2nd group was treated with moxidectin ((0.2 mg/kg body weight) S/C (MG)). Propolis ointment (10%) was applied topically to rabbits of the 3rd group (PG) once daily. Ear scrapes and blood samples were taken on 0, 7, 14 and 21 days. The ear scraping was examined microscopically and the biochemical parameters were estimated and statistically analyzed. The results cleared that moxidectin achieved the complete healing (14th day) faster than propolis ointment (21st day), but MG suffered from a significant (P<0.05) hypoalbuminemia, increased liver and kidney function tests and cortisol levels when compared to PG. Liver and kidney function tests and cortisol yielded good values of the area under the curve, sensitivity%, specificity%, likelihood ratio, PPV%, NPV%, accuracy rate% in DG, MG (except creatinine) and PG. The study concluded that propolis had a prominent antipsoroptic effect without inducing hepatic or renal toxicity. Liver and kidney function tests and cortisol may be useful markers for rabbit mange diagnosis and prognosis and following up its treatment.

The objective designated to discover the analgesic effect of nefopam in the normal (non-stressed) chickens and its possible alteration due to hydrogen peroxide (H2O2)-induced oxidative stress (OS) in 7-14 day old chickens. The analgesia of nefopam has been increased by 47% in the stressed chickens by measuring the analgesic Median Effective Dose (ED50) value. This value was 9.10 mg/kg, IM in the normal chickens where it became 4.80 mg/kg, IM in stressed chickens. There is a significant rise in the antinociceptive action of nefopam 18 mg/kg, IM by 88% in the stressed group of chickens in comparison with the normal one elicited by an electro-stimulation and formaldehyde 0.05 ml of 0.1% tests for induction of nociception. The observations showed several significant stimulatory modifications in the neurobehaviour when nefopam treated with a subtle dosage 1 mg/kg, IM in the stressed chickens concerning the latency to move, squares crossed and time of the tonic immobility response test. Significant damage was detected in the liver function when nefopam injected at 18 mg/kg, IM in stress chickens in comparison to normal one by 28, 33 and 65% as estimated through Alkaline phosphatase (ALP), Aspartate trans-aminase (AST) and Alanine trans-aminase (ALT) concentrations in the serum, respectively. The sum of data findings indicated that H2O2-inducedOS increased the analgesic activity of nefopam in the chickens; despite the changes occur on the neurobehaviour and liver function. The dose of nefopam should be reduced when preparing the therapeutic regimen in the stressed animals.

The study aimed to investigate the analgesic as well as anti-inflammatory effects of diclofenac and silymarin in chicks. The up and down procedure was used to assess the effective median analgesic dosages (ED50s) of diclofenac and silymarin administered intraperitoneally either alone or at the same time in chicks. Also, Analgesic and anti-inflammatory effects were measured by using the formalin test. Isobolographically, ED50s of drugs were assessed for the manner of interaction between both. Formalin testing also supervised analgesic and anti-inflammatory coadministration impact of diclofenac and silymarin at doses 5 and 40 mg/kg and 2.5 and 20 mg/kg respectively.Analgesic ED50s for diclofenac and silymarin in chicks were 10.74 and 83.4 mg/kg separately. Concomitant administration of drugs at a fixed ratio 0.5:0.5 and 0.25:0.25 of their individual ED50 values reduced their ED50s to 2.10:16.81 mg/kg and 3.90:23.50 mg/kg separately. ED50s isobolographic analysis showed synergistic analgesic effects of both drugs. Additionally, coadministration of both drugs had effective analgesic and anti-inflammatory effect, as seen by formalin test, led to a significant rise in latency to lift right foot beside a significant decline in foot lifting frequency when compared with control value, the anti-inflammatory reaction was demonstrated by a significant decrease in foot thickness compared to control value.In conclusion, the data indicate that diclofenac and silymarin coadministration controls acute pain synergistically, and suppress inflammatory reaction.

Flumazenil is choosy and competitive GABA receptor blocker that serves as an antidote to benzodiazepines overdose. Its administration in humans and some animal’s model is connected with nervousness, anxiety responses, or seizures attacks. The objective of this study was to scrutinize the neurobehavioral reaction as well as sedative and anxiolytic actions of flumazenil in chick’s model. The Median effective dose of flumazenil injected chicks was 0.114 mg/kg i.p. Flumazenil at 0.04 and 0.08 mg/kg diminished the locomotors activity, prolonged the period of tonic immobility and have anxiolytic action in chicks. Flumazenil at 0.1, 0.2 and 0.4 mg/kg cause mild sedation in chicks. Flumazenil at 0.1 and 0.2 mg/kg have antagonistic effects in chicks sedated with diazepam at 10mg/kg. Flumazenil demonstrated fairly unexpectedly a depressant effect in the open field test and sedative and anxiolytic bias attention test in the chick’s model. These findings indicate that the impact of flumazenil is indicative of the characteristics of partial agonists when given on its own and antagonist when given after diazepam according to the neurobehavioral tests.

Little works of literature studied the anesthetic effect of ketamine in different ages of broiler chickens, hence this study intended to examine these alterations in chickens at different ages. The doses of ketamine that causes hypnosis in 50% of the chickens (hypnotic ED50) were 7.90, 7.90 and 6.80 mg/kg, intramuscular (IM) at 10, 20 and 40-day-old chickens, respectively, whereas the doses that resulted in analgesia in 50% of the chickens (analgesic ED50) were 12.92, 12.92 and 6.50 mg/kg, IM. The onset, duration and recovery from ketamine hypnosis were in an age-dependent manner and significantly longer at 40-day-old, although the depth and sensitivity of chickens to ketamine hypnosis rises as the age advancing forward. Ketamine analgesia is more effective at 40-day-old. There are neurobehavioral deficits, according to the age of chickens when injecting ketamine in a subtle dose of 1 mg/kg, IM. The concentrations related to alanine transaminase (ALT) and aspartate transaminase (AST), tested in the serum, reveal that the 40-day-old chicken group differs significantly from 10 and 20-day-old chicken’s groups which all treated with single ketamine dose (25 mg/kg, IM). In conclusion, the present work discovered that ketamine’s efficacy, including hypnosis, analgesia and neurobehavioral activity will be increased as the age is progressing, suggesting that the veterinarians need to take it into account when preparing the dose regimen of ketamine anesthesia for different ages of animals.

Aspirin are commonly used analgesic, anti-inflammatory, and anti-pyretic drug in medicine, oral route is the most common one for drug administration as a result it will produce different adverse effects like peptic ulcer, nephropathy, and thrombocytopenia even with low and continuous therapeutic dose, so the alternative topical route is preferable with minimal adverse effects and effective concentration.Therefore, in the present study was to investigate whether the antinociceptive property of aspirin would enhance if used aspirin as nanoparticles after preparing it in several forms (gel, cream and ointment). Thirty-two healthy male mice weighing 30-35 gm. were used in the present study. The animals were divided as a randomized design. Each mouse was treated topically. All drug concentration of aspirin was prepared using gel, cream and ointment as vehicle and topically application on fore and hind paw of experimental animals. Pain was induced by application of hot plate for assessment of latency of pain stimulus. Time from placement to jumping or hind paw licking was recorded as latency of response. The result showed that the median effective concentration (EC50) for analgesic effect of aspirin (gel, cream, and ointment) were 0.848, 0.958 and 1.00% respectively while these EC50s were decrease when used nanoparticles aspirin (gel, cream and ointment) to 0.72, 0.657, and 0.701% respectively. In conclusion, topical applied of aspirin will produce effective therapeutic antinociceptive effects in mice although gel preparation produce a better response followed by cream, then ointment due to pharmacokinetic properties. Also nanoparticle preparation will produce superior response in all forms, whether Nano aspirin is prepared in gel form, cream or ointment.

Lambda-cyhalothrin (LCT) is a type II pyrethroid insecticide, which is widely used to control a large variety of agricultural pests throughout the world as well as in Algeria. The aim of this study was to investigate the effects of LCT exposure on body weight, hematological and blood biochemical parameters and to evaluate histopathological changes in some organs. Twelve (12) healthy local rabbits with a mean body weight of 1.8 kg were divided into three groups of four each: First group was kept as control (CTRL), second group (LCT 10) and third group (LCT 20) were given oral LCT at 10 and 20 mg/kg b.w, respectively three times a week for 25 days. The results showed no significant difference in mean body weight between groups. Blood analysis revealed no significant variation in hemogram between LCT-treated groups and control group. Serum biochemical analysis revealed a significant increase (P˂0.05) in total cholesterol content and glucose in LCT10 and LCT20, respectively. Total protein increased significantly (P˂0.0001) in LCT 20 group. While a very high increase (P˂0.0001) in the activity of asparatate aminotranferase (AST) was recorded in both treated groups, no change was observed in the activity of alanine aminotransferase (ALT). LCT treatment exhibited severe histopathological changes in liver, kidney, lung and brain. It is concluded from the study that LCT produced serious toxic pathological alterations and metabolic dysfunctions in rabbits.

The concentration of heavy metals (Cu, Zn, Cr, Ni, Hg, Pb, and Cd) in the muscles of common carp (Cyprinus carpio) reared in groundwater in Khor Al-Zubair, Basrah province (in the south of Iraq) were assessed using X-ray fluorescence (XRF) spectroscopy. XRF is a powerful technique for element analysis in different environmental samples with many advantages compared with conventional laboratory methods. The mean concentration of the studied metals in the edible parts of the fish (Cr= 11.42, Ni= 2.75, Hg=1.53, Pb= 1.93, and Cd=4.42 mg/ kg dry weight) exceeded the recommended maximum acceptable levels proposed by the Food and Agriculture Organization (FAO)/World Health Organization (WHO), The commission of the European Communities (EC), and Food and Drug Administration (FDA). The results suggest that the tested fish muscle tissue was not safe for human consumption and that the groundwater in the Khor al-Zubair area is possibly contaminated with heavy metals, mainly owing to industrial activity.

The present work was aimed to study the relation between the tapeworm Khawia armeniaca infection and some metabolic extents in both the parasitic tapeworm and the parasitized fish Barbus grypus, using LDH and transaminase activities as a vital connotation. 57 adult Barbus grypus fish (Hekle fish) were hunted from Tigris river - Rashidiya area -North of Mosul - Iraq. The adult tapeworm K. armeniaca were collected from small intestine of the fish. Extract of Liver and intestinal tissues of the infected and uninfected fish in addition to tapeworm tissues were prepared. Some macromolecules concentrations and LD, AST and ALT activities were assayed using colorimetric methods.The results revealed that concentration of proteins, carbohydrates and lipids were lesser significantly at P≤0.05 in the intestinal tissues of infected fish 176.92µg/gm wet weight, 147.21µg/gm wet weight and 112.14 mg/dl respectively than that of uninfected fish 264.70µg/gm wet weight, 223.71µg/gm wet weight and 176.37 mg/dl respectively. Concentration of lipids in the tapeworm tissues was relatively high 130.67mg/dl. As for Liver LDH activity, it was significantly higher in the infected fish 279.90 IU/L than that of the uninfected fish 253.56 IU/L. whereas, liver ALT activity was diminished significantly at P≤0.05 in the liver of uninfected fish. On the other hands, there were no significant different in liver AST activity between the infected and the uninfected fish. There were significant differences at P≤0.05 between activities of the three enzymes in both infected and uninfected fish and tapeworm tissues. On the other hands, AST activity 35.46 IU/L was relatively higher than ALT activity 27.22 IU/L in tapeworm tissues. It is concluded that activitiesofliver LDH and ALT were significantly affected by intestinal tapeworm infection in Hekle fish and may considered as bioindicators for tapeworm infection in fish.

Levofloxacin is a third generation of fluoroquinolones family. It is commonly used in the treatment of a several bacterial infections. However, misusing antibiotics impose damage to hepatocytes and myocytes. The present study was conducted to access the effect of levofloxacin on tissue histology in mice taking in consideration dose and duration of exposure. 24 matured male Albino mice were divided into 3 groups, Group G1: was considered as a control group. They received normal saline intraperitoneally / day. Group G2: They received 10.7 mg/kg/day of levofloxacin intraperitoneally for 10 days. Group G3: They received 10.7 mg/kg/day of levofloxacin intraperitoneally for 3 weeks. Microscopic examination of liver sections of group G2 revealed severe congestion of blood vessels in the portal area and central veins with inflammatory cells infiltration. While in group G3, Apoptosis, Degeneration and necrosis of hepatocytes with giant cell transformation were noticed. In addition to kupffer’s cell activation. Heart sections showed moderate congestion of blood vessels with edema in between the myocytes and inflammatory cells infiltration. Group G3 Necrosis with pyknosis of cardiac muscle nuclei was noticed. We concluded that levofloxacin induces toxic effects on liver and heart according to the dose of administration and duration of treatment.

This study aims to investigate the effect of aspirin in methotrexate toxicity (increase or decrease) relating to oxidative stress and histopathological changes of the liver and kidney in male rats. Twenty rats were divided into equal 4 groups, the first is considered control group, the second was treated with methotrexate in a dose of 10 mg/kg, the third was treated with methotrexate and aspirin in doses of 10 and 30 mg/kg respectively, the fourth was treated with aspirin alone with a dose of 30 mg/kg. All doses were given by daily oral dosage for 4 constitutive days. The result revealed a significant decrease in the concentration of both glutathione and albumin and a significant increase in the concentration of both malondialdehyde and ALT enzyme in the two groups treated with methotrexate alone or in combination with aspirin as compared to the control group. The histopathology revealed that the severity of lesions was in the group of methotrexate with aspirin, group of methotrexate only and a group of aspirin respectively, which are representing by coagulative necrosis and hypertrophy of hepatocytes in the liver while the lesions of kidney were atrophy of some glomeruli and renal cystic formation. The study concludes that aspirin increases the toxic effect of methotrexate at the level of oxidative stress concomitant with the occurrence of hepatic and renal toxicity.

This study aimed to assess the acute toxicity in rats of heated and un heatedbutylated hydroxytoluene (BHT). Sunflower oil dissolved BHT, heated at 98±2ºC by a water bath. The animals were divided into five groups. The control group dosage orally with sunflower oil, the first group treated with 250 mg/kg BHT, the second group treated with 250 mg/kg heated, BHT the third group treated with 500 mg/kg BHT and the fourth group treated with 500 mg/kg heated BHT. All groups received oral treatment. The results showed a substantial reduction in motor activity relative to other groups at a dose of 250 mg/kg heated BHT. There was a substantial distinction in the negative geotaxis test in groups of 500 mg/kg heated and un-heated BHT, while a cliff avoidance test in the heat treated dose of 250 and 500 mg/kg was observed in the cliff avoidance test compared to other groups. A significant reduction occurred in all groups in the pocketing and dorsal tonic immobility test. The pathological changes of heated BHT groups were more severe than those of un-heated BHT groups especially the dose of 500 mg/kg heated BHT. It represented by coagulative necrosis, muscle atrophy in heart, interstitial pneumonia, serofibrinous exudate, pulmonary emphysema in lung and neuronal degeneration, microgliosis, myelin vacuolation and satellitosis in the brain. The study concluded that heated BHT at a dose of 250 and 500 mg/kg had toxic effects to motor and neurobehavioral activity, and histopathological changes in the brain, heart, and lung.

Ractopamine hydrochloride often used as a bronchodilator, but its β-adrenergic agonist effects on un-striated muscle and its withdrawal time have not been assessed for Etawah goats and sheep. The aim of this study was to determine the safe time to slaughter goats and sheep post-treatment with ractopamine. Five clinically healthy adult goats and sheep (20 kg body weight) were treated with a single dose of ractopamine (1 mg, intravenously). Whole blood was sampled from the jugular vein at 120 min, 180 min and 300 min post-treatment. Ractopamine as a veterinary drug was analysed using HPLC at wavelength 225 nm. The concentrations at 120 min, 180 min and 300 min were 817.156 ± 13.460 µg.mL-1, 554.468 ± 50.157 µg.mL-1, and 294.588 ± 52.845 µg.mL-1 in goats and 706.266 ± 89.856 µg.mL-1, 579.194 ± 45.664 µg.mL-1, and 209.36 ± 54.797 µg.mL-1 in sheep, respectively. The withdrawal times in goats and sheep were 1141.710 ± 255.85 h and 989.741 ± 167.633 h, respectively, no drug residues detected. The safe time to slaughter goats after administration of 1 mg of ractopamine was approximately 3 months and 5 days post-treatment at a safety factor of 2, which was later than the sheep at 2 months and 22 days by a safety factor of two.

To explore the benefits of Hydroxychloroquine (HCQ), (which is an antimalarial agent that has shown effective pharmacological properties in different malarial conditions and immunological disorders, particularity in chloroquine-sensitive malaria), in the treatment and prevention of Corona Virus Disease-2019 (COVID-19) pandemic because HCQ was recently advocated to minimize the pathogenicity of COVID-19. The aim of this review is to shed the light on a possible mechanism by which HCQ can defeat the COVID-19, a disease characterized by the WHO as a pandemic. Literatures from Web of Science, Scopus, PubMed, Science Direct and Google Scholar were cast-off to search the literature data. The keywords used are antimalarial agent, COVID-19, Hydroxychloroquine, SARS-CoV-2 and Zinc sulfate.The review summarizes the benefits of using HCQ against COVID-19 through exploiting the ability of this antimalarial agent in ameliorating the body immunity, inhibiting and/or delaying the viral glycosylation by increasing the pH inside the host cell and also via suppressing the viral transcription and replication through the formation of a complex structure after binding with zinc. We concluded thatthese interfering properties of HCQ support human immunity to fight against the progression of COVID-19. We hypothesize that the therapeutic efficiency of HCQ against the COVID-19 can be enhanced by the concurrent administration of zinc sulfate.

This study aimed to evaluate the aqueous extract of Quercus infectoria galls extract (QIGE) as anticlastogenic. The effect of QIGE was tested in mice (5 groups for each test) treated with 7, 12-dimethylbenz (a) anthracene (DMBA), the strong site-specific carcinogenic agent. In this study, the QIGE show no signs of toxicity, a single dose of DMBA (50 mg/kg) was injected intraperitoneally to Swiss albino mice caused a great increase in number of chromosomal aberrations, micronucleated polychromatic erythrocytes (MnPCEs) and reduction in the percentage of mitotic index (MI) (cytogenetic markers). Oral pre-treatment and post-treatment of QIGE for 14 days at dose 2 gm/kg b.w. daily to DMBA-treated animals greatly reduced in number of micronucleus formation, chromosomal abnormalities such as chromosomal break, chromatid breaks, ring chromosome, dicentric chromosome and fragments. Besides, mitotic index frequency increased comparing with the positive control. The data suggest that QIGE has potent anti-clastogenic effect against DMBA-induced genotoxicity in bone marrow cells of albino male mice and it may have a protective effect against the mutagenicity of the polynuclear aromatic hydrocarbons (PAH).

The study was designed to qualitative and quantitative evaluation of the antinociceptive effect of metoclopramide and xylazine each alone or as a concomitant administration in mice. Adult albino Swiss mice weighing 20-30 mg used in all experiments. By using the hot plate test, the individual analgesic dose (ED50) of metoclopramide and xylazine detected depending on the up and down method. Isobolographic analysis used to evaluate the type of interaction between two drugs at the ratio 0.5:0.5 of individual ED50 for each drug at the level of antinociception effect. Simultaneously administration of the double dose of individual ED50 and low doses (sedative, non-analgesic doses) of both drugs, also evaluated at the level of central and visceral analgesia using a hot plate and writhing response test respectively. The individual ED50 of xylazine and metoclopramide was 10.8 and 25.6mg/kg IP respectively. A synergistic interaction at the level of analgesia explored between two drugs at ratio 0.5:0.5 which represented as decreased in ED50 of metoclopramide and xylazine by 58.75 and 58.15% respectively. The animal suffered from only slight sedation and docile. Simultaneously IP administration of xylazine and metoclopramide at double dose of ED50 for each drug-induced significant increase in latency time of thermal response, as well as a significant decrease in writhes number, which induced by acetic acid in comparison with control groups. The percentage of analgesia at sub analgesic doses of a concomitant administration of both drugs was 100% in comparison with each drug alone. These results suggested safe and good use of both drugs in veterinary medicine.

This study aimed to assess the level of testicular damage by observing the changes in the diameter and epithelium thickness of seminiferous tubules in rats that exposure to nicotine per inhalation. Thirty adult male rats were used and divided into five equal groups and treatment as follows for 20 days; Control group NaCl 0.9%, P1 nicotine 0.5 mg/kg, P2 nicotine 1.0 mg/kg, P3 nicotine 2.0 mg/kg and P4 nicotine 4.0 mg/kg. All groups were given treatment per inhalation for twenty days. At the end of treatment and the rats were sacrificed testes were collected for histopathological preparation. The testes were processed for routine paraffin embedding and staining and the sections were examined for histopathological changes. There results showed that nicotine administration induced varying degrees of structural damage to the seminiferous tubules, as the decreased in diamater and epithelium thickness of seminiferous tubules. The diameter and epithelium thickness of seminiferous tubules in four experimental groups reduced compared to the control group. This study proves that nicotine administration does decreases the spermatogenesis of rats by reducing the diameter and epithelium thickness of seminiferous tubules in testes. It also proves that the level of testicular damage is directly proportional to the dosage of nicotine administrated to male rats.

The aim of the present study was to determine the acute toxicity of chlorpyrifos and deltamethrin in mice separately and to study their toxic and neurobehavioral effects. Median Lethal Doses (LD50) of chlorpyrifos and deltamethrin were determined depending on up and down method. The oral LD50 of chlorpyrifos was 193.05 mg/kg and of deltamethrin was 15.71 mg/kg in mice. The oral administration of chlorpyrifos 155 mg/kg and deltamethrin 12.56 mg/kg represent 80% of LD50 resulted in acute signs of poisoning that manifested by dyspnea, salivation and lacrimation at 100%, piloerection, straub tail, tremors, convulsions and death at 70% for chlorpyrifos and 60% for deltamethrin and writhing reflex at 20% for chlorpyrifos. Oral administration of chlorpyrifos 310 mg/kg and deltamethrin 24 mg/kg increased severity of toxicosis signs as a percentage of piloerection, straub tail, tremors, seizures and death 100%. As well as decrease the onset of tremors, convulsions and death, writhing reflex which appears at 20% for chlorpyrifos and 10% for deltamethrin. After three hours of chlorpyrifos and deltamethrin oral administration at doses represent 20% and 10% of LD50 there are significantly hypoactivation in open-field activity, significantly increased in the duration of negative geotaxis performance, significantly decreased in head pocking and swimming scores compared to control group. In conclusion we found that deltamethrin was more toxic than chlorpyrifos this is based on the LD50 value. However, the signs of toxicosis and neurobehavioral effects produced by both toxicants were not differential and could not be associated with the toxic level.

This current work aimed to study the pharmacokinetics of theaflavin in healthy and hepatotoxic rabbits for comparison. Aspartate aminotransferase (AST), alkaline phosphatase (ALP) and alanine aminotransferase (ALT) were significantly raised (P<0.05) after administration of 0.2 mg/kg body weight (BW) Carbone tetrachloride (CCL4) subcutaneously. Pharmacokinetic parameters calculated following administration of theaflavin intravenously and orally at 30 mg/kg and 500 mg/kg respectively to both healthy animals and those with damaged liver. Theaflavin concentration in blood measured by HLPC at various time intervals. Pharmacokinetic results showed that theaflavin concentration when given orally reached its maximum concentration after 5 hours in healthy rabbits. While in hepatotoxic group, theaflavin concentration achieved the highest level in blood after three hours. Theaflavin bioavailability in hepatotoxic animals was significantly high and almost double its bioavailability in healthy animals. Results revealed that the area under curve (AUC) value in rabbits with damaged liver was significantly greater than in healthy group (P<0.05). t ½ of theaflavin after intravenous administration was 6.3±0.82 hour in damaged liver group which is significantly higher than that in healthy group (P<0.05). Theaflavin mean concentration in hepatotoxic group required more than 3 hours to decline to 352±19.4 ng/ml when compared to its concentration in healthy group which is required only 45 minutes to decrease to 310± 9.5 ng/ml. In conclusion liver has critical impact on the pharmacokinetics of theaflavin especially bioavailability and biotransformation and this research recorded reasonably large differences between healthy and liver damaged groups regarding theaflavin pharmacokinetic parameters which may result in negative influences on its biological efficacy when used in the treatment of various diseases.

The aim of this study was to develop convulsion by giving pentylenetetrazol and to observe the interaction of this drug with diphenhydramine and phenobarbital in chickens with an evaluation of the interaction of these drugs and their effect on the biochemical parameters. The chicks were divided into five groups, each group containing six birds, control group injected with normal saline at 2ml/kg, second group injected with PTZ at56.5 mg/kg I.P., third group injected with diphenhydramine at dose 2.5 mg/kg I.M., before 20 minutes from injected of PTZ at dose 56.5 mg/kg I.P., forth group injected with phenobarbital at dose 10 mg /kg I.M., before 20 minutes from injected of PTZ at dose 56.5 mg/kg I.P., fifth group injected with diphenhydramineat dose 2.5 mg/kgI.M. and phenobarbital at dose 10 mg /kg I.M. before 20 minutes from injection of PTZ at dose 56.5 mg/kgI.P. The results showed that group which was treated with PTZ alone showed a significant decrease in glutathione concentration in plasma and brain compare with the control group. All groups except the group treated with PTZ diphenhydramine and phenobarbital showed a significantly increased in malondialdehyde concentration in plasma and brain compare with control group, as well as, all groups except the group treated with PTZ and phenobarbital appeared significantly increased in glucose concentration in plasma compared with the control group. In conclusion, the study appeared oxidative stress result in the lipid peroxidation which main reasons for decreasing of glutathione concentration and increasing of malondialdehyde concentration in chicks.

There were no studies about the analgesic effect of silymarin in the chicken. This study examined antinociceptive effect of silymarin given intraperitonially in 7-9 day-old chicks. The median effective dose of silymarin for the induction of analgesia to electric stimulation in the chicks was 65.3 mg/kg. Silymarin at 60, 120 and 240 mg/kg revealed analgesic effect to electric stimulation in chicks in dose dependent manner in comparison with the control group. The analgesic effect of silymarin at 120 and 240 mg/kg started at 15 min after injection and lasted after over 120 min of injection were as silymarin at 60 mg/kg the analgesic effect started at 15 min after injection and declined before 120 min of injection. The peak of analgesic effect for 60, 120 and 240 mg/kg were at 60 min after injection. These results indicate that silymarin have an analgesic property in the chicks model.

This study aim to use bee venom as alternative medicine for treatment of rats induced with rheumatoid arthritis. Forty rats used for this purpose which divided into four groups, three groups induced with rheumatoid arthritis and one group considered as control group that subdivided into control negative and control positive (rheumatoid group). All the groups induced with rheumatoid arthritis injected with bee venom with different doses (high 40 μg/kg and low dose 10 μg/kg) and different times (after 5 days and after two weeks from CFA injection and along with CFA injection). Glucocorticoid receptor beta used as a biomarker which suggested function as negative regulator determine glucocorticoid sensitivity in target tissues and as an endogenous inhibitor for glucocorticoid action. The high and low dose showed significantly decrease in GCRβ as compared with control group and non-significant between rheumatoid and both along CFA and after 5 days of CFA injection. The pretreatment high and low dose revealed significant decrease in GCRβ compared with Rheumatoid group and non- significant as compared with control group in low dose bee venom treatment. Also, depending on hand paw edema assessment, a weak evidence about anti-inflammatory effects of bee venom has shown. From our data we concluded that bee venom prevents GCRβ elevation especially in pre-treatment group this may result assess to anti-inflammatory effect but the safety of this toxin still needed for another study. Clinically no evidence about the treated effect of bee venom on rheumatoid arthritis in rat.

The aim of this survey is to collect data relating to antibacterial drugs used to treat different animals in the veterinary teaching hospital in the province of Kirkuk, which is taking place for the first time at the province level for the purpose of knowing the types of drugs most commonly used and the outcome whether these drugs used are optimal. Data were collected from the veterinary teaching hospital in Kirkuk province for 6 consecutive months and for the period between 1/7/2016 and until 1/1/2017 period included both the summer and autumn and winter seasons. The results show that the most commonly used drugs were Oxytetracycline, Oxytetracycline, Doxycycline-Colistin compound by 26, 57 and 36% in cattle, sheep-goats and Poultry, respectively. While the least commonly used drugs were Tylosin, Gentamicin and Gentamicin-Tylosin compound by 10, 5 and 4% in cattle, sheep-goats and poultry, respectively. Based on the results obtained from this survey, we recommend the use of Penicillin-Streptomycin compound because it has a synergistic effect against most of the resistant bacteria and not to increase usage of Oxytetracycline because of its side effects and lack of effectiveness in recent times due to the abundance of resistant germs. Also, using antibacterial drugs, we would like to note the need for optimal scientific use of these drugs and to give attention to the period in which it takes the medicine to withdraw from the animal body before milking animals or slaughtering it, so that the bacterial resistance does not develop against these drugs in the future.

Effect of metronidazole on the pharmacokinetics of paracetamol were examined in chicks. Chicks were dosed orally with metronidazole at 350 mgkg of body weight daily (10 -13 days of age). On the last day of metronidazole dosing, chicks injected intraperitoneally with paracetamol at of 50 mgkg of body weight. Paracetamol appeared in chick plasma at 52.00, 45.00, 40.75, 32.75, 23.25 µg ml after 0.25, 0.50, 0.75, 1, 2, 4 hours of injection respectively. A significantly decreased the concentration paracetamol at times of 0.25, 0.50, 0.75, 1, 4 hours post injection and appeared at concentrations of 36.62, 35.37, 25.62, 20.50, 11.00 µgml. These was reflected by changes in the pharmacokinetics of paracetamol as show by the increase elimination rate constant (48%) and decrease in the half-life (32 %) and increase in volume distribution (29%) and increase in clearance by (96%) and decrease in the area under the plasma curve (33%) and decrease in the area under moment curve 65% and lack mean residence time (33%). These results indicate that oral dosing of chicks with metronidazole for four consecutive days and this effect increase in the elemination rate of paracetamol and this effect must be considered when therapy with paracetamol when given during metronidazole therapy.

The present study aimed to investigate the role of silymarin as an antioxidant and/or it activity in induction of the endogenous antioxidants in intact adult male rats. Seventy males were randomly devided into control and  silymarin treated groups (35 each), and were drenched with drinking water and silymarin suspension (200 mg/ kg b.w) daily for 40 days. Each group was allocated to 5 equal subgroups; sacrificed before treatment (0 day), and after 10, 20, 30, and 40 days of treatment. At the end of each period, males were anaesthesized, dissected and blood samples were obtained for assessment of MDA, SOD, CAT and GSH concentrations. liver samples (1 g) have been removed and homogenized for assessment of liver subcellular MDA, SOD, CAT and GSH concentrations. At the end of each periods, serum and liver subcellular MAD concentrations showed no significant changes between groups, whereas SOD, CAT, and GSH concentrations significantly increased at 10, 20, 30, and 40 day periods in silymarin treated males compared with control. It can be concluded that silymarin antioxidant activity is of pharmacological value not only as an antioxidant by itself but also as an inducer of endogenous enzymatic and non-enzymatic antioxidants even in normal intact male.

The current study includes the dual effect of changes in temperature and pH on stability of cefquinome in vitro. Cefquinome was exposed to different phosphate buffer solution with a pH of 6,7 or 8 and each one was exposed to different temperatures which were 30̊C,50̊C or 70̊C in a water bath during 24 hours. Samples were collected after dissolving, after exposure to different pH and after 1,3,6,12 and 24 hours of exposure to different temperatures and pH values. Microbiological assay was used to analyze the samples. The results showed that there was a significant decrease in cefquinome concentrations (antibacterial activity) in alkaline medium with increasing temperature within the time. In conclusion cefquinome is affected by increasing temperature in alkali medium which causes a decrease in its concentration that will affect efficacy of cefquinome due to the degradation process.

The aim of the study is to determine the toxic effect of omega-3 on the neurobehavioral and motor activity in the open field in male rats after 2 and 24 hr of treatment with 2000, 4000, 6000 mg/kg. The toxic effect of the drug on serum glutathione (GSH), malondialdehyde (MDA), triglyceride (TG) and glucose levels in male rats was also studied. In the determination of median lethal dose of omega-3, the result showed wide range of dose 1000–10.000 mg/Kg of body weight given orally without any mortality among the treated animals. The study appeared acute toxic effect of omega-3 by 4000 and 6000 mg/Kg of body weight given orally when compared with the control group. These changes were noticed by a number of neurobehavioral tests after 2, 24 hr of treatment. In open field, there was a significant decrease in the number of cross of squares and time of standing up of the rats. There was also significant decrease in numbers of head entrance in holes in pocking test. A significant increase in the negative geotaxis and cleft avoidance test was noticed after only 24 hours. In swimming test there was a significant decrease in score of swimming, while there was no significant difference in tonic immobility test after 2, 24 hr. However, there was no significant effect on all neurobehavioral tests by the dose 2000 mg/Kg the only significant decrease was noticed in number of head entrance in holes after 2 and 24 hr. In the biochemical tests, omega-3 at doses 4000 and 6000 mg/Kg did not produce a significant changes for serum GSH, MDA, TG, and glucose, compared with the control group. In conclusion, omega-3 is a non-toxic drug. Omega-3 produced neurobehavioral changes in high doses, without any significant change in lipid peroxidation, and serum GSH, TG, and glucose.

A simple technique, using solvent extraction and thin layer chromatography for the detection and separation of a number of commonly prescribed veterinary drugs was studied. Blood and urine have been considered as possible biological samples taken from the animals. The extraction of each sample was done according to the type of the drug as it is acidic or basic, then the extract was spotted on TLC plate by capillary tube after lining the starting line first. Separations of the components of the samples were developed after running the plate in a tight lid tank containing solvent (mobile phase). The identification of separated spots were carried out after lining the end line for the solvent front then by spraying the plate with mercurous nitrate reagent for acidic drugs and acidic iodoplatinate or potassium permanganate reagent for basic drugs. The rate of flow value (Rf) for each compound was measured and the color of spots were determined. This work provides a simple and rapid qualitative technique for the detection of veterinary drugs used at therapeutic doses and in overdosage.

The potent ameliorating effect of ethanol extract of N. sativa seed on the immune system has been assessed in dexamethasone-induced immune-suppressed male rabbits. Fifty mature male rabbits were randomly assigned into five equal groups (control and four treated groups). Animals were daily treated, for 42 days, as follow: C: was orally administered with drinking water; T1: was orally administered with N.s.S.E. (1.5 g/ kg, b.w.); T2: was injected with dexamethasone (2 mg/ kg, b.w., im); T3: was combined treated concomitantly with N.s.S.E. and dexamethasone; T4: was treated with dexamethasone for 21 days followed by N.s.S.E. for 21 days. The results of body weight gain revealed significant increase in T1 and significant decrease in T2 among the experimental groups. Submandibular lymph node weights of T1, T2 and T3 were significantly higher than that of C. Kidneys weights in T2 and T3 registered significant increase compared with C. Bone weight in T1 and T4 groups was significantly higher than that of other groups. Liver weight in T2 was significantly higher and in T4 was significantly lower than other groups. Total leucocytes count and lymphocytes, monocytes and eosinophils percentages were significantly decreased in T1, while showed no significant differences in T2, T3 and T4 groups compared with that of control. Phagocytes activity and bone marrow mitotic index were significantly reduced in T2 group, while returned to normal in T1, T3 and T4 groups compared with control. Titers of IgM, IgA, C3, and C4 showed no significant differences among groups, while IgG titer was increased in T1 and T4 and decreased in T2. On the basis of the results obtained, it can be concluded that the examined extract showed a certain immunomodulating effect. Of the immunological aspects, cellular immunity was potentially ameliorated in intact and dexamethasone-induced immunosuppressed- male rabbits.

Three 1,2 dithiole 3-thion fluoroquinolone esters (2-4) were prepared via condensation of (p-hydroxyl phenyl) -1,2dithiole- 3-thione with fluoroquinolones (Ciprofloxacin, Gatefloxacin and Moxifloxacin). The biological activity of these compounds was assayed against 60 types of cancer cells in vitro. The compound 2 (NSC=760553) showed anticancer activity against renal cell, while the comound 4 (NSC=760555) show activity against three types of cancer cell. The expected mechanism of their activity is that 1,2dithiole 3-thione derivatives may give H2S as new gas transmitter which play an important role in the biological systems.

This study for the evaluation safety of uses propolis at (1%, 2.5%, 5%, 10%) concentrations (alone and synergistically with antibiotic) inside the intramammary the lactation period of the healthy ewes, compared with treated and control groups. The result of safety test indicated that the uses of propolis as intramammary infusion inside the teat cause some effects that disappeared later, like elevation of SCC in milk, decrease in milk yield, prolong residue time for propolis, in addition to the hardness in the consistency of the udder and enlargement the supramammay lymph node when compared with treated and control groups. Also there is significant difference between groups in milk composition. The second trial was to evaluate the Pharmacological activity of propolis preparation and synergism preparation and compared it with antibiotic and control groups in treatment of experimentally induced Staphylococcus aureus Mastitis in the udder of ewes, after confirmed the diagnosis of Staphylococcus aureus strains by Api 20 Staph, one isolate of Staphylococcus aureus was selected based on (its resistance to 10 of 12 antibiotic tested). The infected dose 5 cfu/ml of bacterial suspension was selected to experimentally induced Staphylococcus aureus mastitis in 25 ewes, After the appearance of infection 18 -72 hours post inoculation of bacterial suspension of Staphylococcus aureus in the udder by intramammary route in ewes, the ewes treated paraenterally by antibiotic, antiinflammatory and antipyretic drug and locally in four groups (propolis 1% and 10%) (8 ewes) which appeared very mild side effects, synergism between propolis and antibiotic (4 ewes), antibiotic (12 ewes) and (1 ewe) as control group. The results showed systemic cure in all ewes but with differences in the local clinical cure between groups according to the type of antibiotic and its company production without bacterial cure in all groups , so that make the ewes under the risk of reinfection under any stress condition.

This study examines and evaluates the interaction between imidocarb and diphenhydramine on the level of cholinesterase activity and small intestinal transit (SIT) in chicks. Imidocarb at 45 mg/kg,s.c. significantly inhibited plasma and brain cholinesterases, 30 min after injection by 69 and 21%, respectively. Diphenhydramine at 5 mg/kg, s.c significantly inhibited plasma and brain cholinesterase by 29.7 and 35.7%, respectively and significantly decreased the inhibitory effect of imidocarb on plasma cholinesterase by 33.2%. Imidocarb at 40 mg/kg, s.c. significantly increased SIT 15 and 30 min after injection by 92, 100%, respectively. Diphenhydramine at 5 and 10 mg/kg, s.c., 15 min before imedocarb at 40mg/kg, s.c. significantly decreased SIT produced by imidocarb alone by 80.6 and 70.5 %, respectively and prevented the SIT when given immediately after imedocarb at 40 mg/kg, s.c. by 100%.The data revealed that diphenhydramine has a beneficial effect in controlling the SIT modulated by imidocarb in chicks and there was no adverse interaction between two drugs at the level of cholinesterase.
