Efeito do resveratrol nos órgãos reprodutivos de ratas Wistar obesas

Abstract

The present study aimed to evaluate the effects of supplementation with resveratrol on the reproductive organs (uterus and ovaries) of female rats With diet-induced obesity palatable diet (DPH). We studied 64 Wistar rats were divided into 4 groups: control group (G-CM n = 16): animals fed with commercial feed supplementation Labina ® over placebo (0.5 mL of deionized water, by gavage); Control Group Res + (G-MR n = 16) animals fed commercial feed supplemented with more Labina ® 30 mg resveratrol / kg / day diluted in 0.5 ml deionized water by gavage; group O(G-CO n = 16): animals fed palatable diet (DPH) over placebo supplementation; group O + Res (G- RO n = 16): animals fed with DPH or supplemented with resveratrol 30mg / kg / day. The animals received the diets and supplements for 12 weeks (84 days) and after the experimental period, the rats were euthanized and organs (uterus and ovaries) were removed, weighed and processed for histology. From the results obtained we conclude that supplementation with resveratrol increases ovarian activity evidenced by increase of LCs, as well as in ovarian follicles. In the uterus, the animals that receiving resveratrol was demonstrated by the proliferative capacity characteristic of NORs smaller and in greater quantity.
