conclusions according to the results of this study, vitamin e probably improves the harmful effects of formaldehyde on rat kidney tissue. results comparison of the control and formaldehyde groups with the vitamin e group revealed that there were significant differences in lumen size and nuclear color of proximal tubules in rats treated by vitamin e (p < 0.05). cell degeneration, lumen size, num...

Fifty-day-old Sprague-Dawley females received daily feedings of 10 mg of 3-methylcholanthrene (MCA) in sesame oil for 30 days. Controls received only sesame oil. Thyroid activity was estimated using the thyroid secretion rate (TSR) method. TSR of each rat was determined prior to, during, and after MCA treatment. Average TSR of sesame oil controls did not change either during or after feeding. A...

Background: Methotrexate (MTX), as antimetabolite and antifolate compound, is used to treat the certain types of tissue over activity and cancers. The MTX interferes with cell division through inhibiting the purine and pyrimidine synthesis. Moreover, the toxic impact of the MTX on gonadal tissues has been reported. Therefore, current study was designed to evaluate the protective effects of corn...

Background: Cyclophosphamid as an anti-neoplastic medicine, is classified as a derivative of mustard nitrogen, which passes through brain- blood -barrier and it is known as causing significant poisoning affects with high stoppage effects on body. Through attaching two DNA chains of cell nucleus and breaking inter/intra-chain connection and inhibition RNA synthesis Cyclophosphamide causes high t...

background: vitamin d supplementation during pregnancy has been supposed to defend against adverse gestational outcomes. objective: this randomized clinical trial study was conducted to assess the effects of 50,000 iu of vitamin d every two weeks supplementation on the incidence of gestational diabetes (gdm), gestational hypertension, preeclampsia and preterm labor, vitamin d status at term and...

OBJECTIVE(S) Reproductive dysfunction is a consequence of diabetes. Diabetes is associated with changes in testicular tissue. Sesame oil contains large amounts of polyunsaturated fatty acids and lignin with antioxidant activity, vitamin E, and monounsaturated fatty acid (MUFA). The present study investigated the effects of sesame on testis histology and male reproductive parameters in streptozo...

Background: Atrazine (ATR), an herbicide, is used in order to control broadleaf and grassy weed. ATR has been estimated to impact the testicular tissue both by inhibiting the endocrine system and partly by reducing the antioxidant status. Thus, current study was designed to evaluate the protective effect of vitamin E and testosterone against ATR-induced damages in testicular tissue. Materials a...

this study was conducted in order to evaluate the effect of thyme (thymus vulgaris l.) and oregano (oreganum vulgare l.) essential oils on performance, carcass characteristics, antioxidant status and blood biochemical parameters in broiler chickens. a total of 216 as-hatched broilers (ross-308) were divided into 6 treatments with 3 replications of 12 birds per each. experimental treatments were...
