Change of serum leptin, follicular stimulating hormone (FSH) and luteinizing hormone (LH) in model rats aged 115 days before and a fter feeding them with TGR was measured by radioimmunoassay (RIA). Meanwhile, criter ia of energy state, including diurnal food intake, retroperitoneal fat depot weight and body weight, were measured and evaluated.Results: ASR had the characteristics of high metabolic rate, energy imbalance and obesity. Serum level of leptin increased and FSH, LH decreased significantly (P<0.01) in model rats as compared with the normal rats. Significant positive correlation between leptin level and body weight (r=0.8977, P<0.001) was observed, and negative correlation was seen between FSH, LH and leptin (r=-0.7517, P<0.001; r=-0.8444, P<0.001, respectively). The endocrine changes of ASR all returned to normal range after the TGR treatment.Conclusion: Obesity and concerned hypogonadotrophic hypogonadal anovulation were expressed in ASR. TGR may play an important role in reducing weight and inducing ovulation.展开更多
