Abstract

Background: This study was conducted to evaluate the effect of interaction of sympathetic and opioid systems in the processing of polycystic ovary syndrome modeling in rat.

Methods: Ninety adult female rats (7-8 weeks of age) were treated with EV for 60 days for induction of follicular cysts (PCO modeling). Clonidine and yohimbine were used for sympathic agonist and antagonist and nalterxone was used for opioid system inhibition. Interactions of two systems were studied.

Results: Our results indicate that both systems and interaction of two systems are effective in processing modeling of PCOS in rat. Interaction of two system drugs decreased estradiol (P < 0.05). Qualitative analysis showed that the bulk of cysts and corpus lutea and dominant follicles were increased in PCO rats in comparison with control group.

Conclusion: Therefore there could been an alternative in the treatment of the polycystic ovary syndrome in the rat by using adrenergic agonist and antagonists in combination with naltrexone.
