Testicular atrophy and reduced epididymal sperm count are known to occur after i.p. administration of high doses of hexavalent chromium to rats. The effect of 0.5 mg kg -1 hexavalent chromium injected i.p. 5 d a week for 8 weeks was investigated in male Wistar rats. A significant reduction in epididymal sperm motility was found at the end of the exposure period. The reduction was reversed after an unexposed period of a further 8 weeks. In addition, a decrease in serum testosterone and an increase in FSH were found at the end of the exposure period. The results indicate that a number of mechanisms may be involved in the deleterious effects of chromate on male fecundity.

And Function

This study was designed to investigate the effect of prenatal exposure to synthetic sex steroid on sperm quantity and quality, relative testicular and epididymal weights, and reproductive hormones level in adult Wistar rats. Forty male Wistar rats were divided into two groups: a test group (n = 20) that included mature rats that were born to dams exposed to gestational treatment with hydroxyprogesterone and a control group (n = 20) that included mature rats born to untreated dams. Compared to the control group, the test group showed a significant reduction in the sperm count, viability and motility, relative testicular and epididymal weights together with increased abnormal spermatozoa (p<0.001). The reproductive hormonal assay revealed significantly lower serum testosterone and higher levels of FSH and LH among the test groups compared to the control (p<0.05 for all). Prenatal exposure to synthetic progesterone negatively affected sperm production and function, relative testicular and epididymal weights, and reproductive hormone levels.

Objective: The strong antioxidant activity of <i>Commiphora mukul</i> prompted us to conduct the present study to explore whether treatment with <i>C. mukul</i> extract (CME) would have any protective influence on sperm parameters, testosterone levels, and plasma glucose levels in streptozotocin (STZ)-induced diabetic rats.Methods: Male Wistar rats were randomly divided into four groups: control, control animals treated with CME, diabetic animals, and diabetic animals treated with CME. CME extract (300 mg/kg) was administered for 60 days by daily gavage. Diabetes was induced by an intraperitoneal injection of 50 mg/kg STZ. The epididymal sperm count, weight, motility, morphology, viability, and serum testosterone and glucose levels were determined.Results: In the diabetic animals, CME decreased blood glucose levels (<i>p</i><0.05), increased the total sperm count (<i>p</i><0.05), and decreased the proportion of sperm with abnormal morphology (<i>p</i><0.05). Diabetes reduced sperm motility (<i>p</i><0.001), and CME supplementation partially reversed this effect of diabetes (<i>p</i>=0.003). Furthermore, in diabetic animals, CME decreased the proportion of immotile sperm (<i>p</i><0.001). In rats, diabetes caused a significant decrease (<i>p</i><0.05) in serum testosterone levels (F[3, 28]=3.283, <i>p</i>=0.035), but treatment of diabetic animals with CME increased serum testosterone levels.Conclusion: The present study demonstrated that C. mukul possesses proandrogenic activity and exerts a beneficial effect on sperm parameters in diabetic rats.

Background: During recent years, increasing concern has been raised about the declining sperm count and human male infertility. Cichorium intybus L. (C. intybus) has traditionally been used in Iranian folk medicine as hepato protective and blood purifier and for its presumed fertility-enhancing properties. Objective: A dose-response study was performed to determine the effect ofC. intybus ethanolic leave extract on the reproductive parameters in adult Wistar male rats. Materials and Methods: In this experimental study, 40 healthy adult male Wistar rats (8 wk old, 200-210 gr body weight) were randomly divided (n = 10/each) as control and groups treated with 50, 100, and 200 mg/kg/day of C. intybus extract via gavage for 70 days. Serum hormonal assay, epididymal sperm evaluation, and analysis of morphometrical parameters, antioxidant enzymes, and lipid peroxidation levels of testis were done in each experimental group. Results: Weights of testis and epididymis increase significantly in male rats treated with 200 mg/kg C. intybus extract. Sperm density and percent of morphologically normal sperm were significantly increased in a dose-related manner with C. intybus treatment. Serum testosterone was higher at 100 and 200 mg/kg C. intybus extract-treated groups. C. intybus significantly reduced malondialdehyde levels and also increased superoxide dismutase and glutathione peroxidase activity in testicular tissue of rats. Conclusion: It is concluded that C. intybus leave extract improves reproductive parameters in male rats which might be a consequence of both its antioxidant and androgenic properties.

Pesticides are known to result in toxic insult. We aimed to evaluate Judo 40, the commercial formulation of chlorpyrifos on the neurological activities, fertility, and hormone levels of male rats. Male Wistar rats were treated orally with 1 mL of 20 or 50 mg/kg Judo 40. The doses were administered four times, twice a day. Sexual and exploratory behavior indices, fertility indices, serum androgen levels, blood acetylcholinesterase (BChE) levels, and neurological and muscular effects were evaluated. Serum testosterone and luteinizing hormone were significantly reduced in the rats receiving 50 mg/kg Judo 40. A reduction in viable implantation sites and live pups born were evident in the female rats mated with the male rats treated with the highest dose. Similarly, in the rats treated with the highest dose of Judo 40, a significant reduction in plasma BChE enzyme was observed. According to the results, prolonged Judo 40 exposure can cause impairment of the neurological alterations and sex hormones leading to impaired fertility. Therefore, chemical handlers should be educated on protection and risk minimization.

AbstractThe aim of this study was to compare the effects of acute (a single injection) and chronic (21 consecutive days) treatments with chrysin 2, 4, and 8 μmol kg−1 on anxiety-like behavior and Fos immunoreactivity in the lateral septum nucleus (LSN), a structure that is involved in the regulation of anxiety, in male Wistar rats. These effects were compared with the clinically effective anxiolytic diazepam 7 μmol kg−1. The results showed that acute, but not chronic treatment, with 4 μmol kg−1 chrysin exerted anxiolytic- and anti- depressant-like effects with these effects being similar to that of diazepam. Also, none of the above-mentioned treatments did alter Fos immunoreactivity in the LSN, but a tendency towards the reduction of this variable was detected with chrysin 4 μmol kg−1 and diazepam 7 μmol kg−1. Altogether, results suggest that chrysin exerts anxiolytic-like effects, however, it can produce pharmacological tolerance after repeated use, similar to benzodiazepines.

Background: Medicinal plants are of great importance to health of individual and communities. About 80% of the population in Uganda relies on traditional medicine because western-trained medical personnel are limited especially in villages. Most Ugandans use Hymenoxys odorato for medicinal purposes e.g. to treat colds, fever, coughs, anti-helminthes, locally used as tea, anti-allergy and also as an anti-venom to relieve snake bites. Method: A group of 25 male wistar rats of 150 g&ndash;210 g were kept for 14 days while being fed and treated with the extract. At 14th day, anesthesia was given and blood samples collected by cardiac puncture for hematological and biochemical investigations. Serum was analyzed for Alkaline Phosphatase, Aspartate Transaminase and Alanine Transaminase while whole blood was used for complete blood count. The liver and kidney were removed and placed in 10% formalin to prepare for histology staining using haematoxylin and eosin technique. Results: The extract elevated hepatic biomarker enzymes i.e. ALP, ALT and AST. The increase was found to be significantly different (P &gt; 0.05) at 400 and 500 mg/kg doses as compared to the control group. Histological sections of the liver showed distortion of liver cytoarchitecture, steatosis, necrosis of hepatocytes and congestion of the sinusoids at high doses 300, 400 and 500 mg/kg body weight. In the sections of the kidney, there was mild distortion of the integrity of the kidney with glomerular hypercellularity at high doses (400 and 500 mg/kg per body weight). Conclusion: Hymenoxys odorato aqueous extract has toxic effects on the liver and kidney of wistar rats. The effects were observed to be in a dose dependent manner.

Acrylamide is a chemical that naturally forms in starchy food products during every day high temperature cooking. The ingredients, storage and processing conditions greatly influence acrylamide formation in food.  Home-cooking choices can have a substantial impact on the level of acrylamide humans are exposed to through the diet. This study scientifically determined the neurologic impact of acrylamide treatment and recovery in male wistar rats of different ages. A total of 20 male wistar rats were randomly sampled into 4 groups aged 45, 60, 75 and 90 days. The treatment dose was 50 mg/kg of acrylamide for 7 days. The study duration was 15 days with 2 phases; day 1 to 7 for exposure phase and day 8 to 14 as recovery phase after acrylamide exposure. Neurologic tests performed include open field test (OFT), buried reward test (BRT) and hand grip test (HGT). The study data was statistically significant at a confidence interval less or equal to 95%. Acrylamide adversely affected the tested physiologic responses in all ages during the phase of exposure. The distance covered and escape attempts were significantly reduced        in all ages during acrylamide exposure phase with significant recovery in 45 and 60 days old animals. Group 45 and 60 days old animals had a wider field area during recovery phase but no observed improvement in exploratory behavior in ages 75 and 90 days. Olfactory and neuromuscular function was significantly improved in all age groups during recovery, however, the response of ages 45, 60 and 75 were similar during recovery. In this study, Acrylamide caused manifestations typical of a neurotoxic agent. The neurologic effect of acrylamide may be reversed if exposure period with the studied dose is within 7 days. Recovery in cognitive, exploratory, emotional, olfactory and neuromuscular function may be dependent on age during exposure.
