This work was aimed to explore the details of the ion channels gating and there physiological role in sperm in the future.Mouse spermatozoa express a pH-dependent K+ current (KSper) thought to induce hyperpolarization to enhance Ca2+ influx via alkaline-activated calcium channel (Catsper) to initial a so-called sperm capacitation by NH4Cl during travelling in female genital tract for fertilization. However, the regulating mechanism of the Ksper and Catsper channels by membrane potential and pHi remains uncertain, because the complexities of two channel kinetics in sperms is hardly to be overcame at this stage. Here we show that difference of the intracellular [Ca2+]i between the wild type (Wt) and knockout (KO) Ksper (or Slo3/) mice in the application of the Slo3 blockers, Guinidine (QD) and Clofilium, and NH4Cl, indicating that Ksper channels, encoding Slo3 gene, dominates the membrane potential of mouse sperms to increase the intracellular [Ca2+]i and [pH]i during the capacitation process to play a vital role in fertility. Furthermore, a HH model sperm built directly with the native Ksper and Catsper currents in sperms reveals two functions of membrane potential and intracellular pHi, allowing us to calculate the intracellular pHi by NH4Cl, based on membrane potentials recording from current-clamp experiments. During modeling, we found a caton channel with Vrev= +20 mV in mouse sperm from the double-KO (i.e. Catsper-/- and Ksper-/-) mice, which is definitely necessary for a model able to match the data.

The present study was aimed to record and analyze the prevalence of obstructive urolithiasis in domestic animals like cattle, buffalo, horse, goat, sheep, dog and cat presented at RVP-TVCC, Indian Veterinary Research Institute. A total of 777 cases were reported during the academic session starting from April 2018 to March 2019 from Bareilly and its surrounding regions. Incidence were highest among ruminants 92.92% comparing to other domestic animals 7.08%. Among the different animal species, caprine were found to be the most affected, followed by buffalo and canine. A positive correlation was noted between the occurrence of obstructive urolithiasis and the season with maximum number of cases being reported during the winter season December - February. The female to male ratios in urolithiasis affected animals were 1:81, 1:75 and 1:22 for buffalo, goat, and dog, respectively indicating higher occurrence in male animals. Majority of the goat 67.89% and buffalo 84.80% presented with obstructive urolithiasis were also found to be fed exclusively with a grain rich diet that are excess in phosphorous thereby contributing to urolith formation. The role played by behavioral changes associated with different seasons and the dietary status of the animal plays a significant role in the pathophysiology of urolithiasis. Such an interplay between the season and the dietary imbalance will lead to higher incidence of obstructive urolithiasis in domestic animals.

This study aimed at detecting the effects Coenzyme Q10 alone and with vitamin E supplementation on some semen quality and seminal plasma parameters of broiler breeder males Ross 308. Twenty-five males 43weeks aged were divided into five groups (5 rooster/ group) with five replicates (1 rooster / replicate), the first control group included drenching with corn oil capsules only. The second and fourth groups were about drenching with capsules containing Coenzyme Q10 at a concentration of (5 mg / bird) alone and with 10 mg of vitamin E daily intake. Whereas the third and fifth treatments included drenching with capsules containing the Coenzyme Q10 at a concentration of (10 mg / bird / day) alone and with 10 mg of vitamin E respectively. The results showed a significant increase (P<0.05) in the ejaculation volume, both individual and mass motility in addition to sperm concentration, particularly the fifth treatment. Furthermore, the results clear a significant decrease in the percentage of dead and abnormal sperms. The Coenzyme Q10 alone and with vitamin E led to improved semen quality marking a reduction in AST and ALT, glucose concentration and total protein with improved antioxidant status referring to a high level of glutathione (GSH) and low malondialdehyde (MDA). We conclude from this study that Coenzyme Q10 with and without vitamin E has the ability to improve the semen characteristics of age-old broiler breeder males and can improve the status of antioxidants in semen.

Inhibins are important ovarian hormones that control the action of the pituitary gonadotropins which regulate the ovarian cycle. The present experiment aims to study the role of steroid-free follicular fluid-antibodies (S-FBFF-ab) on the reproductive hormone levels at estrus and metestrus phases in cycling female rats. Follicular fluid was collected from mature ovarian follicles, centrifuged and treatment with activated charcoal. S-FBFF was isolated and used for immunization of adult male rabbits. After 5 injections, blood was withdrawn for separation of S-FBFF-ab. Eighty mature female rats were assigned into control and treatment groups (40 each). At late metestrus phase, females of the control were injected intra-peritoneally with 100 μL of physiological saline, whereas treated females were injected intra-peritoneally with 100 μL of S-FBFF-ab. At early estrus and early metestrus phases of each estrous cycle, serum concentrations of inhibin-B, follicle stimulating hormone (FSH), estradiol (E2), and prolactin (PRL) were estimated. The results revealed that S-FBFF-ab has inhibin immuno-neutralization effect, which caused elevation in the concentrations of serum FSH and E2, and significant decline of serum PRL and inhibin-B, at early estrus, whereas significant elevation of E2 and PRL, and significant decline of serum FSH, at early metestrus. Furthermore, the results of gene expression revealed a significant elevation of ovarian aromatase gene at both early estrus and early metestrus phases, whereas pituitary PRL gene showed significant decline at early estrus phase and significant elevation at early metestrus phase. In conclusion, passive immunization against S-FBFF could augment the reproductive efficiency through increase reproductive endocrine activity.

The current study aims to investigate the role of steroid-free follicular fluid antiserum on ovaries morphometric growth and development in virgin female rats at two sequential estrous cycles. Bovine follicular fluid aspired from graafian follicles, steroids were removed by treatment with activated charcoal, in order to obtained steroid-free bovine follicular fluid (S-FBFF) which was used for immunization of male rabbits to prepare S-FBFF antiserum (S-FBFF-ab). Sixty virgin female rats were assigned into control and treatment groups (30 each), intraperitoneal injected with a single dose of distilled water 100µl/rat and S-FBFF-ab 100µl/rat at late metestrus, respectively. At the estrus phase of the first and second estrous cycle, 15 females from each group of each cycle were anesthetized and ovarian samples were obtained for histological examination. In comparison with control, the results of S-FBFF-ab treated female rats revealed a significant increase of relative ovaries and uteri weights at both estrous cycles. Morphometric examination showed progressive ovarian proliferation at the first estrus phase in S-FBFF-ab treated female rats through elevation of the number of primaries, graafian, and total follicles. In conclusion, passive immunization against endogenous inhibin using S-FBFF-ab could augment the reproductive fecundity through increase ovarian growth and development.

Prosopis farctais belonged to Mimosaceae family, commonly known as mesquite. It was chosen to investigate their effect on α-glucosidase inhibitory activity (in-vitro), serum glucose and liver functions. Roots, fruits, and leaves of P. farcta, were extracted by n-hexane, ethyl acetate, and methanol. α-glucosidase inhibition was analyzed by using ELISA technique then half maximal inhibitory concentration IC50 was found. The blood glucose levels were determined with a glucose analyzer model. The serum alkaline phosphatase (ALP), Alanine transaminase (ALT), aspartate aminotransferase (AST) and serum total bilirubin (TB) were estimated by using the Cobas diagnostic kit with a fully automated chemical analyzer. Diabetes was done by a single dose of 120 mg alloxan/kg b.w with subcutaneously injection. Ethyl acetate extracts of P. farcta showed the higher α-glucosidase inhibitory activity, and the best one was root extract. Treatments of the alloxan-induced diabetes rats were done by daily oral administration of different concentrations with P. farcta extracts of ethyl acetate for 28 days and the dose 200 mg/kg BW was the effective one. The root extract was the best one for reduction of serum glucose followed by leaves then fruits. Administration of root extract of P. farcta showed a decrease in the levels of ALP and TB in alloxan-induced diabetes rats. The fruit extract of P. farcta showed decreasing in the level of ALP in alloxan-induced diabetes rats. In conclusion, the P. farcta extracts for ethyl acetate have properties of hypoglycemic effect as well as improving some parameters related with diabetic complications of liver functions.

The disaccharides, consisting of sucrose, lactose and maltose, are hydrolysed into monosaccharides (D-glucose, D-galactose and D-fructose) by intestinal brush border enzymes: sucrase, lactase and maltase. The aim of this study to investigate changes in the brush-border membrane carbohydrate digestive enzymes. From intestinal mucosal scrapings of equine, brush border membrane vesicles were isolated. The results showed that sucrase, maltase and lactase are present in the equine small intestine. The activity of all three enzymes is highest proximally (in the duodenum and jejunum) and lower in the ileum. There was considerable variation between individual horses, however the majority showed highest disaccharidase activity in the jejunum, with some showing highest activity in the duodenum. Sucrase activity is highest in the jejunum and duodenum and lower in the ileum. Maltase activity is similar in all three regions, but slightly higher in the jejunum. Lactase activity is low in all three regions of the small intestine, slightly higher in the equine jejunum and duodenum than ileum. From this study, we can conclude that the equine small intestine digests disaccharides by the brush-border associated disaccharidases sucrase, maltase and lactase. Levels of sucrase and lactase are comparable to other species, but maltase is much higher.

Used 45 male pups in the age of weaning, were randomly divided for 3 groups each group included 15 pups of each sex. 1st group was a control group, 2nd group exposed to chronic heat stress at 38Cº for 1hour a day since the age of weaning until onset of puberty and the 3rd group exposed to acute heat stress at 38Cº for 4 hours per day for 5 consecutive days from 35 day age of rat and each group above were secondarily divided into 3 age groups consisted of pre-puberty, at puberty and post-puberty. Results of study showed that male rats exposed chronic heat stress led to a significant increase in body weight, tail of epididymis, prostate gland weights, at onset of puberty compared with control group, with a significant decrease in body weight, testis, head and tail of epididymis, prostate and seminal vesicle weights at post-puberty compared with control group. as well as a significant decrease in the level of luteinizing hormone at post-puberty compared with acute heat stress group. Males exposed to acute heat stress cause a significant decrease in the head and tail of the epididymis, prostate, and seminal vesicle weights and significant increase in the concentration each of testosterone and luteinizing hormones at post-puberty compared with the control group. Acute exposure to heat stress caused early sexual puberty in males to show from the early appearance of first sperm compared with the control group, while the exposure to chronic heat stress led to delay of puberty associated with a delay in the appearance of first sperm compared with the control group. It concluded from this study that male rat's exposure to heat stress affects differently on sex hormone. Acute heat stress led to reach early sexual puberty and reflected the impact on puberty when chronic exposure to heat stress.

The aim of the study was to estimate the level of cadmium, zinc and oxidative stress parameters in serum and milk as well as the blood constituents in local at the age of 3-4 years during the spring and summer seasons. Blood and milk samples were collected from 30 ewes (15 each season). The blood samples were allocated to into two tubes, for complete blood profile study and for biochemical analysis. Milk was used for biochemical tests. Blood analysis showed a significant difference between some blood values during the two seasons represented by significant increase of total white blood number, haemoglobin concentration and packed cell volume in circulating blood of lactating ewes during summer season compared with spring season. Red blood cells number and mean corpuscular haemoglobin concentration did not change among the two seasons. Both mean corpuscular volume and mean corpuscular haemoglobin value of lactating ewe increased significantly during spring season with respect to the summer season. The serum glutathione level showed a significant elevation during spring season compared with the summer season, while, the level of malonaldehyde and peroxynitrite free radicle remain constant during the study period. There were no significant changes in the level of cadmium in serum and milk of examined ewes, while the serum level of zinc significantly higher during the spring compared to the summer season and milk zinc level remain stable during both seasons. The study concluded variations in haematological, oxidative stress biomarkers, serum and milk concentration of Zn and Cd according to lactation season in ewes.

The purpose of this study was to evaluate the renoprotective effect of the Garcinia mangostana L. pericarp extract (GMPE) on plasma creatinine and renal proximal tubules of streptozotocin-induced diabetic mice. This study used 36 male Balb/c strain mice. The samples were divided into 6 groups, namely KN (normal control), KD (diabetic control), KM (metformin control), and P (treatment group) comprising: P1 (50 mg GMPE/kg body weight), P2 (100 mg GMPE/kg body weight), as well as P3 (200 mg GMPE/kg body weight). The GMPE and metformin suspension were administered orally for 14 days on the diabetic mice. The diabetes was induced by intraperitoneal injection of STZ multiple at low-dose of 30 mg/kg body weight daily for five consecutive days. On day 15, mice were terminated. Data of plasma creatinine and renal proximal tubule damage levels or the number of swelling and necrosis cells were analyzed. Interestingly and it showed that administration of GMPE could reduce the plasma creatinine level and the ameliorate renal proximal tubules of streptozotocin-induced diabetic mice. In conclusion, the renoprotective effect of GMPE in streptozotocin-induced diabetic mice was associated with the attenuation in oxidative stress and inflammatory, which also had antidiabetic and antioxidant activities.

This study was conducted to investigate the possible protective role of (CoQ10) on reproductive dysfunction of male rats induced by sodium fluoride (NaF). thirty two rats were divided into four even groups and treated for 56 days as follows: the first group served as control (C) The second group (G1) received coenzyme Q10 at dose of 10 mg/Kg.B.W; while third group (G2) received 100ppmsodium fluoride in drinking water and fourth groups (G3) received NaF 100 ppm and CoQ10 10 mg/Kg.B.W for 56 days. The results showed that exposure of rats to NaF caused decrease in serum testosterone (T) and luteinizing hormones (LH) concentrations. Whereas Administration of CoQ10 caused an increase the concentrations of theses hormones in group G3 as compared with group G2. Testicular morphometric and histopathological alterations were observed in group G2 in the form of marked microvacuolation in the basal level of germinal cells, amyloid deposited within seminiferous tubules with disarrangement and depletion of germ cells. Whereas testicular histological alterations were improved in rats treated with CoQ10. In conclusion, the results of the present study showed that use of Co Q10 can alleviating the deleterious effects on male reproductive function following exposure to NaF, may be via improvement the testicular functions or other related endocrine glands.

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.
