Effect of arsenic on ovarian steroidogenesis at the dose available in drinking water at wide areas of West Bengal is reported here. Weights of ovary, uterus and vagina along with biochemical activities of ovarian delta 5-3 beta-hydroxysteroid dehydrogenase (delta 5-3 beta-HSD) and 17 beta-hydroxysteroid dehydrogenase (17 beta-HSD) and plasma levels of LH,(More)
The present work examined the changes in testicular activities in relation to testicular oxidative stress in cyclophosphamide as well as human chorionic gonadotrophin (hCG) co-treated cyclophosphamide treated Wistar strain rats. Testicular activities were evaluated by the quantification of spermatogenesis and by the measurement of steroidogenic key enzyme(More)
AIM To study the detrimental effects of cyclophosphamide on the testicular androgenic and gametogenic activities through endocrine inhibition and/or induction of oxidative stress in male albino rats and to evaluate the protective effect of ascorbic acid. METHODS The testicular D5, 3b-hydroxysteroid dehydrogenase (HSD), 17b-HSD, peroxidase and catalase(More)
Arsenic, a major water pollutant in India, produces toxic effects on female reproductive system in rodent models at the dose available in drinking water in arsenic-intoxicated zones. This study examines the coadministration of L-ascorbate (vitamin C) on ovarian steroidogenesis, plasma levels of gonadotrophins, brain monoamines, and ovarian as well as(More)
Effects of ascorbic acid supplementation on the activity of acid phosphatase (ACP), alkaline phosphatase (ALP), glutamic oxaloacetic transaminase (GOT) and glutamic pyruvic transaminase (GPT) on liver, kidney and serum in cyclophosphamide-treated female virgin rats were investigated. Oral administration of cyclophosphamide at the dose of 5 mg/kg body(More)
The present study was undertaken to evaluate the dose-dependent effects of a leaf extract of Stephania hernandifolia on testicular activities in albino rats. Whether this leaf extract has any toxic effect on metabolic organs or on the liver or kidney was studied. Adult male Wistar rats, maintained under standard laboratory conditions, were forcefully fed(More)
The purpose of this study was to show the effect of cold exposure on testicular activities in breeding and hibernating seasons in the toad. Adult male toads were placed in a cold chamber in both breeding and hibernating seasons for periods of 7, 14 and 21 days. At the time of sacrifice on the 15th and 22nd days, cold-exposed animals showed a decrease in(More)
Quantitative evaluation of ovarian Delta5,3beta- hydroxysteroid dehydrogenese (HSD) and 17beta - HSD activities along with radioimmunoassay of plasma levels of gonadotrophins (FSH and LH), and estradiol (E2), and quantification of different types of developing follicles and regressive follicles were noted in mature rats of the Wistar strain following(More)
Steroidogenic key enzymes, i.e. delta 5-3 beta and 17 beta-hydroxysteroid dehydrogenase (delta 5-3 beta and 17 beta-HSD) activities, in the testis and Bidder's organ of the toad were inhibited and ascorbic acid synthesis in these organs was decreased by a wide range of lithium concentration in in vitro study. A significant inhibition was noted at a(More)
Injection of lithium chloride at the dose of 200 micrograms/toad/alternate day for 7, 14 and 21 days caused a significant reduction in the activities of testicular delta 5-3 beta, 17 beta-hydroxysteroid dehydrogenase and acid phosphatase enzymes. There was a marked inhibition in spermatogenesis in lithium chloride treated toad for 14 and 21 days of(More)
