In this study, pieces of skin from common carp (Cyprinus carpio L.) fish were collected freshly from juveniles from a privet fish farm in Duhok city, Kurdistan-Iraq. Those pieces of skin were cultured In Vitro by using two methods of explanting; direct explants and enzymatic pre-digested explants of tissue fragments. The results showed a highest cell yield (5×103 cell/ml) on passage 2 of enzymatic pre-digested tissues and higher cell growth rate in compare with cell yield (38×102 cell/ml) gained from direct explant tissues. Both procedures showed forming of clumped cells colonies in initial passages (P1 and P2), and the morphological changes were developed in both cells to show a fibroblast like appearance thereafter. Such findings are important and advantageous to suggest a faster and more efficient protocol for tissue culture cells isolation with lower cost and better isolation success as well.

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 objective of this study was to identify the levels of Blood Urea Nitrogen (BUN) and its relation to the reproductive efficiency and serum progesterone concentration in lactating Holstein Friesian dairy cattle. Data were obtained by stratified random sampling from population to get 18 dairy cows, which divided into three groups. The first, second, and third groups each with milk yield of less than 17, between 17-21, and over 21 liters/day, and with calving interval of less than 365, between 365-450 and more than 450 days. Blood was collected from the coccygeal vein at the time of insemination (D0), 7 day (D+7) and 22 days (D+22) after insemination. BUN and progesterone concentration were measured. Data analysis showed no significant difference (P>0.05) on the observed parameters. Data regrouping based on BUN concentration showed that the mean of services per conception (S/C) was lower and conception rate (CR) was higher (P<0.05) in dairy cattle having BUN<18 than those of with BUN>18 mg/dL. The mean of progesterone concentration at D+22 was higher (P<0.05) than those at D0 and D+7 in pregnant dairy cows and with BUN<18 mg/dL, as well as those at D+22 in non-pregnant dairy cows with BUN>18 and BUN<18 mg/dL. This study concluded that high BUN concentration affect the reproductive efficiency of dairy cows by decreasing CR and increasing progesterone serum concentration.

The present study was designed to evaluate the effect of administration of lecirelin acetate, hCG and progesterone after AI on ovarian picture, serum progesterone concentrations and first service conception rate in cross-bred cattle. A total of 160 lactating cross bred (Friesian x Sahiwal) cattle were divided into 4 groups after AI. The groups were treated as follows: control (injected i.m with normal saline 2ml, n=40), d 7-LA (injected i.m with lecirelin acetate100 µg, n=40), d 7-hCG (injected with hCG 3300 IU, n=40) and d 7-P4 (injected i.m with Progesterone 0.5 mgdaily for 4 days, n=40) group. The hormonal treatments were given to animals on day 7 after AI. The ultrasonography and blood sampling was done before treatment and then 7 days later. All animals were examined for pregnancy through ultrasonography at 40 ± 1 day after AI. The diameter of SCL on 7 days after treatment was higher (P < 0.01) in group d 7-LA and d 7-hCG group cows as compared to control cows. In contrast, the diameter of SCL in d 7- P4 treated cows did not differ from control cows. Formation of ACL was observed only in 50 % & 80 % cows in d 7-LA and d 7-hCG group respectively. No ACL was observed in control and d 7- P4 cattle on day 7 after treatment. The P4 concentrations were significantly higher (P < 0.01) in d 7-hCG treated cattle as compared to control at 7 days after treatment. As compared to 10 percent First Service Conception Rate (FSCR) in controls, an increase (P < 0.05) of 50 percent and 40 percent was observed in each treatment group (d 7-hCG & d 7-LA), non-significant (P > 0.05) difference in FSCR was observed between control and d 7-P4 group. It was concluded that the use of hCG or LA, 7 days after AI is a beneficial tool to improve conception rate in cross-bred cattle whereas use of parental P4 post-breeding has no effect on SCL diameter and conception rate.

Mammary gland tumors in dogs rank second among all newly diagnosed tumors in this species. Research goalwas to study clinical/morphological characteristics of breast cancer in dogs with the use of ultrasound investigation. 34 dogs of different breeds and age groups with spontaneously emerging neoplasms of mammary glands were chosen for the study. To classify malignant tumors, the histological classification was applied. Complete examination of breast tumors was carried out with the help of clinical observation, ultrasound, radiologic, hematological and ultrasonographic methods applied. The largest percentage (23.5%) of animals with mammary gland neoplasms are mongrel female dogs. The breed predisposition was detected in dogs of the following breeds: Miniature Schnauzer - 11.9%, Standard Dachshund - 11.9%, American Bulldog, American Cocker Spaniel and Miniature Poodle - 8% each. Breast cancer was diagnosed in 29 animals (85.3%), 100% of those cases in the nodular form with microcalcifications in the tumor parenchyma. The horizontal orientation of growth is more often typical of breast cancer in the mammary gland pairs I and II at the initial stage of carcinogenesis, and is characterized by an inhomogeneous hypoechoic structure with sufficiently pronounced boundaries detected during the ultrasound investigation. The vertical orientation of growth is mainly typical of breast cancer in the mammary gland pairs III, IV and V from the very beginning of the disease. The ultrasonography usually shows: inhomogeneous hypoechoic structure containing inclusions in the form of cords or foci of a higher acoustic solidity; also clearly defined lateral acoustic shadows and dorsal echo enhancement; as well as unevenness and indistinctness of borders. The performed histological study within the current research revealed a multifocal, infiltrating epithelial neoplasm with distinct edges, surrounded by a large amount of fibrous tissue. The tumor consisted of a number of acini with a tendency of forming a network structure. The shape of cells was detected from round to irregular, the cytoplasm was found scarce, often with uneven borders, with the large central core, with chromophilic substance and 1-2 nucleoli. The cells were characterized by the pronounced anisocytosis and anisocariosis, and a great number of mitotic figures. Lymphatic invasion was observed. Ultrasound investigation of the mammary gland allows for performing percutaneous minimally invasive interventions and differential diagnostics of cystic and solid lesions of the mammary gland (96-100% accuracy), mastopathy and carcinoma conditions.

Thirty local Iraqi ewes reared in Tikrit – Salah-edin province from first the of October-2016 to the first of March-2017 were used in the current study to investigate the influence of pregnancy on levels of some biochemical and minerals contents in the blood serum. Blood samples were collected from ewes before and monthly during pregnancy (first, second, third, fourth and fifth month), serum separated and stored at 5 °C until samples analysis. All samples were analyzed by spectrophotometer with special kits for each parameter. Results demonstrate significant decrease (P ≤0.05) in concentration of total protein, cholesterol and glucose as pregnancy advanced, while there is no effect of pregnancy on the concentration of creatinine and magnesium, however, there is a significant increase (P ≤0.05) in calcium concentration as pregnancy proceed. In conclusion the pregnancy has clear influences on the concentration of total protein, cholesterol, glucose and calcium. The measurements of these parameters give best assessment for nutritional and health status of Iraqi ewes during pregnancy.

The present study was designed to detect resistant site of nalidixic acid through transformation and plasmid curing of S. aureus strains isolated from buffalo milk with subclinical mastitis and workers’ hands. A total of 37 S. aureus isolates including 17 isolates recovered from buffalo milk infected with subclinical mastitis, in addition to 20 isolates recovered from workers’ hands. All 37 isolates were investigated by detection of the 23S rRNA gene and various other species specific genes including coa, nuc and clfA. The antibiotic resistance of S. aureus isolates was performed by the discs diffusion method using 19 antibiotics. Plasmid transformation method was carried out by transferring the plasmid isolated from S. aureus into competent Escherichia coli HB 101 in order to detection the resistant site of nalidixic acid. Plasmid curing was accomplished by preparing different concentrations of nalidixic acid (100, 150, 200, 250 and 300 µg/ml) and cultured transformed E.coli on LB agar supported with each of the aforementioned concentrations. The molecular results showed that six isolates (five isolates from milk samples and one from workers’ hands) were identified as S. aureus by coa, nuc, and clfA species specific primers. The six S. aureus isolates were found to be resistant to at least 5 antibiotics which included the nalidixic acid. The results of plasmid transformation revealed that E. coli was able to grow on LB agar supported with 100µg/ml, 150 µg/ml, 200 µg/ml and 250 µg/mlof nalidixic acid and failed to grow on 300 µg/ml concentration.

Research was undertaken to establish an inventory of ticks on dogs in the north east of Algeria. In the first aspect of study, a survey aims to identify of Ixodidae infesting the dogs in bioclimatic different areas and to determine the risk factors. This work took place between 2006 and 2012. The results of the collections show that all the dogs, which were the subject of this survey, are infested by ticks during the period between March and August in different areas of the northeastern of Algeria. Rhipicephalus sanguineus is the predominant tick species. It has been observed with a frequency of 88 % in the area of El-Tarf, 100 % in Souk-Ahras, 95 % in the Tébessa region and 72 % in Guelma, (average of 89 %). Climatic conditions seem to play the essential role for this distribution of ticks. The other tick species collected are: Ixodes ricinus, Rhipicephalus turanicus, Haemaphysalis punctata and Hyalomma anatolicum. The latter were present with very low a proportion, which gives them the appearance of accidental parasitism in dogs. Rhipicephalus sanguineus has significant infestation intensity in spring and summer, peaking in August in the semi-arid region (Souk-Ahras). In humid regions (El-Tarf), the peak of infestation recorded by this arthropod is in April. The second aspect of study of the seasonal dynamics of Rhipicephalus sanguineus shows the seasonal nature (Spring-Summer) of the brown tick of dog.

Pseudomonas (P.) aeruginosa possesses a variety of the virulence factors that may contribute to its pathogenicity, such as exotoxin A (toxA) and exoenzyme S (ExoS). The principal aim of this study was to find out the rapid method for identification of P. aeruginosa and to detect the toxA, exoS and16SrRNAgenes by Polymerase Chain Reaction (PCR) technique. Other aim on the other hand, the DNA sequencing was performed for phylogenetic tree analysis of 16SrRNA gene in local pathogenic P. aeruginosa isolates in comparison with NCBI-Genbank global P. aeruginosa isolates and finally submission of the present isolates in NCBI-Genbank database. According to the detection of the 16S rRNA gene, the study revealed that 29 (58%) and 32 (64%) of P. aeruginosa out of 50 swabs obtained from each wound and burn areas were positive. whereas in addition, the result of this study showed that the toxA gene was detected in 77% of P. aeruginosa isolated from the wound and 51% of P. aeruginosa isolated from the burn. whereas, the exoS gene was detected in 69% of P. aeruginosa isolated from the wound and 49% P. aeruginosa isolated from the burn. BLAST analysis showed that the 16S rRNA gene shared more than 99% homology with the sequences of P. aeruginosa. Furthermore, the phylogenetic tree analysis of the 16S rRNA gene indicated that (PA-IQw and PA-IQb) the 16S rRNA gene shared higher homology with other four P. aeruginosa isolates available in the GenBank. The homology of the nucleotides was between 99.9% and 100%.

The present study was aimed to determine the scolicidal effect of stem and root alcoholic extract of Punica granatum L. (Pomegranate) on the viability and fatty acids content of Ecinococcus granulosus protoscolices. The study elucidate the scolocidal effect of both stem and root extracts. Its seemed that the scolocidal effect of root extract was higher than that of stem extract ie. LC50 and LC90 of stem extract were 5 and 9 mg/ml respectively while LC50 and LC90 of root extract were 3 and 8 mg/ml respectively. GLC analysis of E. granulosus protoscolices was stated presence of nine fatty acids esters, which were Lauric (C12:0); Myrisitic (C14:0); Palmatic (C16:0); Stearic (C18:0); Archidic (C20:0); Behenic (C22:0), which were saturated fatty acids, and Oleic (C18:1); Linoleic (C18:2); Linolenic (C18:3) which were unsaturated fatty acids. Treating E.granulosus protoscolices with LC50 of pomegranate stem bark was showing slight and swing effect on fatty acid content, while treated the protoscolices with LC50 of root bark were resulted in obvious increase in short length fatty acids like Lauric, Myrisitic and Palmatic in compare with control group. In contrast the long chain fatty acids concentration like Oleic, Linoleic and Linolenic were decrease.

This study aimed to investigate the impact of supplementing different levels of Nigella sativa oil in rations of growing lambs. In a feeding experiment lasted 90 days, 18 growing Ossimi lambs (6-7 months old) were randomly divided by weight into three equal groups (6 animals each). Individual animals in all groups were fed a uniform total mixed ration, offered at 3% of body weight, where the first group was without supplement (R1), while Nigella sativa oil was supplemented at 0.1 (R2) and 0.2% (R3) of dietary DM. Results indicated that additions of N. sativa oil didn’t influenced feed intake, but it increased average body weight gain and feed efficiency. Nutrients digestibility values and dietary nitrogen utilization were higher with N. sativaoil rations than control. Ruminal fermentation parameters showed comparable pH values among groups at 0, 3 and 6 hrs. of feeding. Ruminal NH3-N concentration was lower and TVFA concentration was higher for animal fed R2 and R3 rations than control. It’s concluded that N. sativa oil could be added at 0.2 % of the daily feed as a natural growth enhancer of lambs.

This study was designed to evaluate the cytotoxic effects of cadmium chloride (CdCl2) on thyroid and adrenal gland of male rats (Rattus norvegicus). Thirty six male rats were used and randomly into three groups each of 12 rats, the first group(G1) kept as at control. The 2nd and 3rd groups (G2 and G3) were administrated orally cdcl2 at doses of 15 and 20 mg/kg.B.W. respectively for 6 weeks. After the treatment period, the rats were sacrificed, then thyroid and adrenal glands were removed and processed for light microscope. Light microscopic examination of thyroid gland with (15mg/kg.B.W.) showed increase in the size of follicles, some of these follicles appeared empty from any colloidal substance and heavily infiltrated by inflammatory cells, with depletion of parafollicular cells. Vaculated follicles may be clear in other sections, and showed congested blood vessels, vascularized stroma, hyperplasia of thyrocyte in rats treated with 20 mg/kg.B.w. Results also noted changes in different regions of adrenal gland related to rats exposure tocdcl2 with 15 mg/kg.B.W., these includes cellular debris, necrosis of cortical cells, amorphous material in the zona fasciculate and focal necrosis in zona granulosa with disruption of normal structure and replaced by necrotic cells and inflammatory cells, also obvious adipocytes infiltration which appeared clear in medulla. Most changes occurred within the adrenal cortex and appeared more severity than that in the medulla region. Hypereosinophilia, pyknotic nuclei, congested blood vessels, hemorrhage, degeneration and inflammation also seen in both regions (cortex and medulla) of adrenal gland from rat exposed to cdcl2 at 20 mg/kg.B.W.

Issues of safety are very crucial with biomaterials and medical devices. Sixteen male New Zealand White rabbits equally into four groups: Group A, rabbits had part of their radial bone (2 cm, mid shaft) and left empty as a control. Group B, rabbits were implanted with scaffold 5211. Group C, rabbits were implanted with scaffold 5211GTA+Alginate. Group D, rabbits were implanted with 5211PLA. All scaffolds were prepared by freeze-drying method. Blood samples were collected at day 0 and 1st, 2nd, 3rd, 4th and 8th week after implantation. The blood examination included complete hemogram and certain serum biochemical parameters. The results showed that there was no significant difference (P>0.05) among each treatment group in comparison with control group (day 0). However, red blood cells, hemoglobin, packed cell volume, mean corpuscular hemoglobin concentration, monocyte, plasma protein, inorganic phosphate, sodium, chloride and urea were significantly increased (P<0.05) among treatment groups at week 8. An abnormal architecture of viscera was observed in all animals, thus indicating a form of toxicity related to the degrading scaffold materials. The severity of histopathological lesions in viscera was not coated polymers dependent nor development materials. In conclusion, implantation of 5211 scaffold with or without coated framework has a significant impact on histopathological and certain hematological and biochemical parameters.

Sutchi Catfish is one of the important fish commodities in Indonesia. Unfortunately, its seasonal spawning pattern causes limited supply. Cryopreservation is a solution to solve limited supply since it can store the spermatozoa in low temperature so that physiological, biological and morphological functions still remain. Improving the quality of cryopreservation is important to increase the success of Sutchi Catfish aquaculture. Adding honey in cryopreservation process is expected to increase the quality of spermatozoa since it contains with sugars as a source of spermatozoa’s energy. This study tried to compare the effectivity of honey in cryopreservation process with no addition. The treatments used in this study were T1 (0% honey), T2 (0.2% of honey), T3 (0.4% of honey), T4 (0.6% of honey) and T5 (0.8% of honey). 30 days after stored, the spermatozoa were checked their motility, viability, abnormality, fertility and hatching rate. This study showed that honey addition could increase the motility significantly (P<0.01) to 23.14% better than control. The viability increased significantly (P<0.01) to 23.17% better than control. The abnormality test did not show significant difference between honey addition and control although the abnormality value in control was the highest (10.75%). The fertilization rate increased significantly (P<0.01) to 28.85% better than control. The hatching rate increased significantly (P<0.01) to 29.78% better than control. The success of all test indicated that the addition of honey in cryopreservation process of spermatozoa could be performed on Sutchi Catfish to increase its production even though the limited spawning pattern.

The study was aimed to improve the productive performance of white laying hens, using two types of medicinal herbs, including turmeric and Artemisia Herba. In the experiment 63 laying hens (white shevar) were used at an age of 24 weeks, hens were divided randomly in to three treatment 21 hens pre treatment with 3 replicate of 7 hens per replicate. A standard ration was used without any addition, which was considered as the control treatment (T1), the basic ration, plus turmeric powder (0.5%) (T2), while the treatment (T3) represented the basic ration plus Artemisia Herba powder by 0.5%. The study included the measurements of egg production, egg weight, feed consumption, feed conversion ratio and egg mass. The results showed a significant improvement (P<0.05) in the characteristics of egg production ratio, feed conversion ratio and egg mass for the treatment with the addition of Artemisia Herba flower (T3) compared with other treatments, and significant decrease (P<0.05) in the amount of feed consumed (T2, T3) as compared with the control treatment (T1), while the results did not show any significant differences to addition of turmeric to the ration (T2) in the productive performance as compared to the control treatment. It was concluded from that the addition of Artemisia Herba to the ration resulted in a significant improvement in most of the productive performance of laying hens as compared to other treatments

Newcastle disease is a highly contagious disease of domestic and wild birds result in huge economic losses due to extreme morbidity and mortality. The aim of this paper is to explore the possibility of the harmful impact of Newcastle disease vaccine on certain biochemical profiles regarded to chicken liver. This study conducted during January-April 2014, one day old - 53 chicks were divided into two groups; vaccinated (with Newcastle disease vaccine) group at the age of 1, 3, and 7 days and unvaccinated group. Results show damaging effects of vaccination on the liver glycogen and malondialdehyde concentrations, serum superoxide dismutase, catalase, glutathione peroxidase, gamma-glutamyl transferase, alanine transaminase, and aspartate transaminase activities. In contrast, studied parameters look to return to their usual range at the age of 30 days. From the convincing outcome of our investigation, it can be concluded that Newcastle disease vaccination has a detrimental influence on the liver of chickens, nonetheless this effect can be overwhelmed by the time.

Frozen semen quality is one of many factors that promote successfully of artificial insemination. Preservation at 5ºC is one of the steps of semen freezing to obtain high fertility sperm after added with the extender. This study was aimed to determined the sperm quality (motility, viability, and membrane integrity), MDA level and DNA damage of post-thawed sperm after being preserved at 5ºC for different duration. Bali cattle bull semen collected by artificial vagina. Macroscopic and microscopic evaluation of ejaculate was conducted first. Qualified semen was diluted in Tris Aminomethan-Egg yolk and then devided into two treatment group: preserved at 5ºC for 4 hours (first group) and 22 hours (second group), and continued to processed into frozen semen, and stored overnight. Pre-freezing and post-thawed of semen analysis was conducted based on SNI: 4869-1:2017 of The National Standardization Agency of Indonesia. Measurement of levels of Malondialdehyde (MDA) was conducted by spectrophotometry at 532 nm wavelength, meanwhile measurement of sperms DNA damage percentage was performed by Toluidine blue staining. The result of showed that quality of post-thawed sperm (motility, viability, and membrane integrity) was higher (P<0.05), and MDA level and DNA damage were lower (P<0.05) in preservation at 5°C for 22 hours compared to those of 4 hours. It could be concluded that preservation at 5°C longer (22 hours) means sperm had longer chance to adapt with the extender, this implies the higher quality and lower lipid peroxidation.

This study investigated the role of vitamin C and Citrus Sinensis peel (sweet orange peel (Sop)) on growth, carcass characteristics and health status in 160 one day old broiler chickens (Ross308) which were randomly divided into four equal groups consisting 4 pens. Each pen having 10 birds (5 male and 5 female) for 35 days. All chicks were exposed to heat stress (330C) during all the experimental period (35 days). Group one considered as control, groups 2, 3, 4 were given feed containing vitamin C (500ppm/ feed), sweet orange peel (Sop) (1,2 % respectively). Sop 2% significantly increased average body weight gain and feed intake during the grower period (16-28) (P<0.05). The birds fed Sop 2% during the whole experimental period had higher FI and greater feed conversion ratio (P<0.05) compared to the other groups. The mortality rate tended to be the lowest in the birds fed the feed additives (P<0.05). The relative weight of internal organs, blood profiles pictures were not affected by Sop with two tested levels (P<0.05) or vitamin C compared with the control group. Broiler fed vitamin C or Sop levels had greater primary and secondary antibody responses to sheep red blood cells (SRBC) and against phytohemagglutinin (PHA-P) antigen compared with those in the control group (P<0.05). Sop and vitamin C increased antibodies titer against Newcastle disease during the secondary antibody response (P<0.05). Overall, Sop as feed additive improved immune responses in broiler chickens under heat stress. Also the result indicate that the Sop 2 % during the grower period had a positive effect on growth performance of broiler chickens under heat stress.

Studies had been previously conducted to genetically identify species of ticks in Iraq. Therefore, the current investigational study was conducted to recognize the species of 50 ticks collected from infested skin of cattle. The current study defined the ticks to be from Hyalomma genus depending on theirmorphological features. Using mitochondrial cytochrome oxidase subunit I (CoxI) gene, 16 ticks were further confirmed using polymerase chain reaction (PCR). Two PCR products were subjected to DNA sequencing to name the species of the ticks and compare them to some other known ticks in neighbor and world countries. The sequencing results identified the ticks to be Hyalomma anatolicum. One isolate is closely similar to Indian and Iranian isolates, and the other isolate is clustered alone by itself. The results indicated that H. anatolicum is one of the wide-spread ticks that affect cattle in Al Najaf province, Iraq.

The aim of this work is to study lamb births and mortalities in Algerian sheep Ouled Djellal breed distributed in different zones of Tébessa region, which is divided according to bioclimatic stage, staff in livestock and area agricultural vocation, into four distinct zones: northern (A, B), middle (C) and southern zone (D). During two years 2015-2016, birth numbers (BN) and mortality rates (MR) of 355 sheep flocks were recorded using a questionnaire. Concerning BN the total number was 21244 lambs representing a mean 59±31 per flock. No significant differences between the birth means of C and D (75±28 vs 83±30) were registered. Birth mean was significantly higher (P<0,05) in B (40±17) than A (29±10), when comparison with C and D, the births of A and B were highly significantly (P<0,001). According to (BN) the studied region were classified into 3 zone groups: (a) with high lambing rate (C, D); (b) with medium lambing rate (B); (c) with low lambing (A). In regard to mortality rates, the total rate was 24±6%. The (MR) in A (27±5%) was significantly higher (P<0,05) as compared to other zones (B) 24±4%, (C) 23±7% and (D) 22±4%. However, no significant differences between B, C and D were revealed. According to the results of (MR) the studied region was classified into two groups: (a) with low MR (C, D), (b) with high MR (A, B). Our result showed that zones influence the (BN) and (MR) in Tébessa region, and southern zones especially D seems the appropriate to practice breeding of Ouled Djellal breed.

This study aimed to evaluate the benefits of using platelet– rich plasma (PRP) on wound healing. The study performed on ten adult male dogs, aged 2-3 years and their weight were 18-25 kg. Under the effect of deep sedation and local subcutaneous anesthesia at the site of wound, four of (2x2) cm of full-thickness square cutaneous wounds were induced, two on each side of the lateral thoracic region of each animal. A pair of left wounds was treated by injection with 5 mL of autonomous PRP (treatment group), 2 mm lateral to the wound edges and in the wound center., immediately after wounding while, right wounds, were injected with a single dose of 5ml of sterile saline (control group) by using the same procedure as in treatment group. The clinical and histopathological evaluation of each group for five weeks, histological biopsies were taken in the days (3, 7, 14, 21, 28 and 35) of the experiment. The clinical evaluation of PRP treated wounds showed that the wound healing process (% contraction, % re-epithelization and % total wound healing) were significantly more (P<0.05) than the control wounds during the five weeks study. The histopathological results revealed that PRP treated wounds have enhanced cellularity, increased vascularity, with increased amount of granulation tissue accompanied by increase numbers of skin appendages suggesting enhanced cutaneous regeneration, than those in untreated wounds. Depending on the clinical and histopathological findings, this study confirms that local implantation of PRP leads to acceleration and improvement cutaneous wound healing.

Low Power Laser Irradiation therapy raises the levels of proliferation for the variety of cells. Although despite very little is recognized about its effect on the proliferation levels and possible nuclear morphological changes of mice mesenchymal stem cells, which derived from bone marrow and adipose tissue. This study examined the effects of the different fluence of 1, 2, 3 and 4 j/cm² with different dose durations on promoting proliferation, viability and possible nuclear morphological changes of mice mesenchymal stem cells. The growth curves have been used to analyse the proliferation of all the applications. Fluorescent stain (DAPI) (4’-6-diamidino-2-phenylindole) staining used to check the nuclear alterations at 72 hours, while the trypan blue assay used to test the cell viability. Mesenchymal stem cells that derived from bone marrow responded to LPLI in a dose-dependent manner. The higher cell growth determined once the cells irradiated with a fluence of 4 j/cm², especially after 24 hours (P<0. 01). Whereas adipose tissue-derived stem cells responded better to a fluence of 2 j/cm² after 48 hours (P<0. 05). There was no significant change in nuclear alterations and in cell viability detected in the studied groups. LPLI permits a significant increase in the proliferation of stem cells, without causing nuclear alterations, therefore, increasing the number of differentiating cells for tissue engineering, regenerative, and healing processes.

Diazinon (DZN) is a commonly used Organophosphorus (OP) pesticide to control a variety of insects in agriculture and in the environment. The aim of this project is to study the effects of organophospherous pesticide (Diazinon) on histological and histochemical of kidney in male rabbit. The present study is based upon observations made on 24 male Baladi rabbits, which was divided into: 3 groups: Eight animals each, the whole body of the rabbit was dipped in 10 liters of the diazinon solution, while sparing the head for 10 seconds. Group one (control group) was dipped in water only. Animals of Group 2; were dipped in diazinon solution dipped every 2 days for 4 weeks, and Group 3 were dipped in diazinon solution every 7days for two months. Decreased in body weight was noticed in group 2 and group 3 may be due to increases in the exposed doses and increased accumulation of DZN in the blood of the exposure animals. Histological changes in group 2 and 3 are similar, renal tubules were severely damaged with cytoplasmic vacuolation and atrophy of some glomeruli. Blood capillaries in between the degenerated tubules were congested; the urine spaces are widening, and fibrosis inters tubules in group 3 only. Exposure of animals to diazinon caused extensive changes in histopathologicaly as well as histochemicaly in the kidney of group 2 and group 3. But very marked changes in group 3.

The aim of this study was to evaluate the sedative effect of xylazine alone or as a combination with chloropromazine, and to check the possibility to induce analgesia by the use of sedative (sub analgesic) doses of this combination in chicks. The analgesic ED50 of xylazine (S.C.) and chloropromazine (I.P.) was 0.9756 and 8.598 mg /kg respectively. Depending on Isopolographic analysis, the drug interaction between xylazine and chloropromazine at ratios of 1:1, 0.5:1 and 0.5:0.5 of the analgesic ED50 of xylazine and the sedative ED50 of chloropromazine was synergistic interaction. The injection of sedative (non – analgesic) doses of xylazine (0.5 mg/kg body weight, S.C.) and chloropromazine (4.3 mg/kg body weight, I.P.) together induced deep sedation with excellent analgesia in 100% of the animals in comparison with each drug alone at the same doses. There were no significant differences in glucose levels between the group of xylazine (0.5 mg/kg body weight, S.C.), a group of chloropromazine (4.3 mg/kg body weight, I.P.) or group of xylazine (0.5 mg/kg body weight, S.C.) and chloropromazine (4.3 mg/kg body weight, I.P.) together compared with the control group. Therefore, the combination sedative doses of xylazine and chloropromazine (low doses) can be considered as an ideal mixture for good analgesia in chicks.

 The current study included examination of 1525 buffaloes from (11) districts in Mosul city for detection of lice and ticks. Results showed that the total percentage of lice infestation was 48.63%, particularly blood sucking lice Haematopinus tuberculatus. Buffaloes reared in Al-Shalalate and Al-Kabate showed 100% lice infestation, sucking lice H. tuberculatus was diagnosed by thorax plate which was rectangular with the presence of anterior process on each side. The length of male was 3.5-4 mm while the length of female was 4.5-5 mm. Total tick infestation was 49.1%, with a heights percentage of 80% was noticed in Al-Kabat. Three species of hard ticks were identified, namely Hyalomma anatolicum, Boophilus annulatus and Rhipicephalus sanguineus. H. anatolicum was diagnosed by the following characteristics: half circular capitulum; chilecera consist of 3 long pieces, bifurcated first coxa, breathing plate is comma shape, festoon is present with the presence of 2 sub anal plates project out of the body. In R. sanguineus, the capitulum is six angled with short mouth parts. The first coxa was bifurcated with presence of festoon. Breathing plate was comma shape. In B. annulatus the capitulim was six angled with short mouth parts. The first coxa was triangular in shape with short legs and absence of festoon while the breathing plate was oval or rounded in shape.
