Nonylphenol, an environmental estrogenic chemical, is reported to have adverse effects on the reproductive organs of animals. In this study, the metabolism of nonylphenol and that of other alkylphenols in the rat liver was investigated using liver perfusion. Alkylphenols (nonylphenol, hexylphenol, butylphenol, and ethylphenol) were glucuronidated by rat liver microsomes. Nonylphenol was found t...

amiodarone is used in treatment of cardiac arrhythmias. therapeutic use of amiodarone is limited by its side effects, including pulmonary toxicity. human placenta extract (hpe) contains a variety of bio-active substances. thus, the present study aimed to quantitatively evaluate the protective effects of hpe on the structural lung changes induced by amiodarone using stereological methods. spragu...

objective: to determine the effects of topical administration of 20% oltipraz solution on histomorphometrical and stereological aspects of skin tissue in full thickness skin wounds in laboratory rats. methods: thirty-six male wistar portion rats (220±20 g) were randomly divided into three groups (n=12). on the first day of experimentation, a 1-cm 2 circular wound was made on the posterior surfa...

the aim of the present study was stereological evaluation of testes of azoospermic animal model using busulfan in rat. three groups of male adult rats were used in this study. the first group was injected by single dose of busulfan (10 mg kg-1) and their testes were removed on day 35 post injection. the second group received double doses of busulfan with 21 days interval and their testes were r...

Background: DZN (diazinon) is an organophosphate insecticide that had been used in agriculture and for domestic and veterinary use for several years and caused many negative effects on plants and animal species, especially on human. The aim of present study was to evaluate the effects of DZN on MDA (malondialdehyde) and GSH (glutathione) levels in female rat reproductive tissue (ovary) and to...

This study was organized to see whether vitamin E, as a strong antioxidant, could affect the abnormalities of testis structure caused by para-nonylphenol (p-NP) during its development. A total of 32 female Wistar rats after mating were divided into four groups (n = 8): control, vitamin E (100 mg kg(-1) per day), p-NP (250 mg kg(-1) per day) and p-NP + vitamin E. The rats were treated from the s...

background: the role of oxidative stress in endosulfan-induced reproductive toxicity has been implicated. this study was performed to evaluate the possible protective effect of vitamins e and c, against endosulfan-induced reproductive toxicity in rats. methods: fifty adult male sprague–dawley rats were randomly divided into five groups (n=10 each). the groups included a control receiving vehicl...
