The aim of this study was to investigate the effect of magnesium sulfate (MgSO4) on experimental unilateral varicocele-induced in rats. Sixty male Wistar rats were randomly divided into six experimental groups (n = 10).The Control group had no received any medications and surgery. The Sham group had noreceived any medication, abdominal cavity was opened without varicocele-induced. Varicocele group: abdominal cavity was opened, varicocele done without any medication treatment. In group abdominal cavity was opened, varicocele-induced then animals orally treated with MgSO4 (25mg/kg) for 42 days. The groups 5 and 6 were similar to group 4, except animals received 50 and 100 mg/kg of MgSO4, respectively. At the end of days 21 and 42, the abdomen was opened, the left testis extracted for histopathological studies. Also, from the cauda epididymis semen samples were collected to determine malondialdehyde, superoxide dismutase and glutathione peroxidase values. According to the results, there was a significant difference in testis damage grade in Varicocele group compared to the Control group (P < 0.05). The MgSO4 significantly improved testis damage grade on day 42 (P < 0.05). The MgSO4 treatment, dose dependently improved seminiferous tubules with many spermatocytes in the seminiferous tubules in experimental unilateral varicocele established rats after 21 and 42 days (P< 0.05). Also, administration of the MgSO4 via a dose dependent manner significantly normalized malondialdehyde, superoxide dismutase and glutathione peroxidase values to the physiologic level in varicocele-induced rats after 21 and 42 days (P< 0.05).These results suggest administration of the MgSO4 protects testis against unilateral varicocele in rat.

Purpose: To determine the effect of folic acid (FA) on experimental testicular ischemia/reperfusion (I/R) in rats. Methods: Sixty male Wistar rats were randomly divided into 6 groups. The control group received physiologic saline orally. The sham-operated group received physiologic saline orally then exposed to midline laparotomy without clamping the IR. The I/R rats received oral gavage of the saline then subjected to 1h ischemia /24h reperfusion, period. In folic acid (2mg/kg+IR) rats received oral gavage of the FA (2mg/kg) then subjected to 1h I/24h R. groups 5-6 received FA (5 and 10 mg/kg), then subjected to 1 h I/24 h, respectively. At the end of the study, semen samples were collected for spermatozoa characteristics. The left testis was removed for histological analysis and superoxide dismutase (SOD), malondialdehyde (MDA) and glutathione peroxidase (GPx) measurement. Results: Spermatozoa mobility, mortality (%) significantly decreased in I/R group (P 0.05). Dose dependent increase observed on spermatozoa mobility, mortality (%) using different levels of the FA (2, 5 and 10 mg/kg) treated rat (P 0.05). Tissue MDA levels significantly increased in I/R rat (P 0.05) while FA (2, 5 and 10mg/kg) in a dose dependent manner decreased I/R-induced MDA (P 0.05). Experimental I/R significantly decreased SOD and GPx activity (P 0.05). Administration of the FA (2, 5 and 10mg/kg) significantly increased tissue SOD and GPx activity in I/R rat (P 0.05). Seminiferous tubules degenerated and loss of spermatogenesis with few spermatocytes was observed in degenerated testis tubules in I/R rat. Orally administration of the FA (5 and 10 mg/kg) improved testis characteristics with few normal seminiferous tubules and spermatocyte in seminiferous tubules in experimental I/R-induced rat. Conclusion: The treatment of folic acid had a benefit effect against ischemia-reperfusion.(AU)

PURPOSE:To investigate the protective effect of metformin on testicular ischemia/reperfusion (I/R) injury in rats.METHODS:Eighteen adult male Wistar rats were randomly divided into three experimental groups (n=6), as follows: Sham, I/R, and Metformin. 1-hour ischemia was induced by the left testicular artery and vein clipping followed by 7 days of reperfusion. Metformin (100 mg/kg) was administrated orally for 7 days via oral gavage after ischemic period. At the end of trial, the left testis was removed for histological analysis and oxidative stress measurement.RESULTS:I/R reduced superoxide dismutase (SOD) activities and testicular Johnsen's scores accompanied by an elevation in malondialdehyde (MDA) and myeloperoxidase (MPO) levels in comparison with the sham group (P < 0.05). Compared to I/R group, metformin restored testicular Johnsen's scores, SOD activity, MDA and MPO levels (P < 0.05).CONCLUSION:Metformin has a protective effect against I/R injury on the testis.(AU)
