Comparison between resveratrol and cabergoline in preventing ovarian hyperstimulation syndrome in a rat model

Abstract

Objective: The aim of this study is to investigate the effects of resveratrol in a rat model of ovarian hyperstimulation syndrome (OHSS) and compare with cabergoline.Design: Randomized controlled, animal study.Animal(s): Female Wistar rats.Material and methods: A rat OHSS model was used to investigate the effects of resveratrol compare with cabergoline administration for preventing OHSS. Body weight, ovary weight, diameter, vascular permeability (VP), vascular endothelial growth factor (VEGF), cyclooxygenase-2 (COX-2) expression (immunohistochemistry), and serum estradiol (E2) levels were then compared.Results: The ovarian VEGF concentration was significantly increased in the OHSS Groups (Groups 3–5) compared with the control groups (1 and 2). But vascular permeability, VEGF, and COX-2 expressions were reduced in animals treated with the resveratrol group compared with the cabergoline group (group 5) and the severe OHSS (group 3) group. Blood E2 levels were decreased in group treated with the resveratrol group compared with the cabergoline group (group 5) and severe the OHSS (group 3) group.Conclusion(s): Our results in a rat model suggest that resveratrol has a beneficial effect on OHSS by reducing the increases in ovarian daimeter, VP, and VEGF expression associated with OHSS. These effects may be mediated by the COX-2 inhibitory capacity of resveratrol.
