Synergistic effects of Trans-anethole and L-dopa on serum concentration of adiponectin in rat model of PCOS

Trans-anethole is a steroidogenic plant derivative. Adiponectin secretion and dopamine release is lower in patients suffer from polycystic ovary syndrome (PCOS). In the present study the effects of interaction of trans-anethole and L-dopa were investigated on serum concentration of adiponectin in PCOS model rats. Following estradiol valerate- induced PCOS, forty-five PCOS rats in 9 groups received saline, trans-anethole (50 mg/kg), L-dopa (100 mg/kg), sulpride (10 mg/kg), SCH23390 hydrochloride (1 mg/kg) or simultaneous injections of these drugs via intraperitoneal injection. Five intact rats received saline. Blood samples were collected via tail vein. Serum concentration of adiponectin was determined by ELISA. Mean serum concentration of adiponectin significantly decreased in PCOs rats compared to intact group. Adiponectin concentration in PCOS rats receiving trans- anethole or L-dopa significantly increased compared to PCOS group. Simultaneous injections SCH23390 hydrochloride and sulpride inhibit the stimulatory effects of L-dopa on serum concentration of adiponectin via exerting synergistic effects. Simultaneous injections of trans- anethole and L-dopa synergistically caused a significant increase in serum concentration of adiponectin compared to PCOS group. Trans-anethole as a steroidogenic plant derivative, may be an effective agent for increasing the activity of dopaminergic neurons and controlling the metabolic complication derived of decreased levels of adiponectin secretion in PCOS.
