ABSTRACT
Objective:
To observe the effect of Jiuwei Chushi Decoction on sex hormone level of serum and Kisspeptin protein expression in hypothalamus of Central Precocious Puberty (CPP) rats model.Methods:
After sixty female rat were breeded from SD rats, they are randomly divided into six groups, which are normal control group, model group, Gonadorelin group, and high, medium and low dose group of Jiuwei Chushi Decoction, 10 in each group. In addition to the normal control group, the other groups were subcutaneously injected with N-methyl-DL-aspartic acid to establish CPP model. Gonadorelin group was subcutaneously injected with Gonadorelin 100 μg/(kg·d), and high, medium and low dose group of Jiuwei Chushi Decoction were intragastrated with Jiuwei Chushi Decoction extract at 5.75, 2.87 and 1.43 ml/(kg·d) respectively. The levels of Luteinizing Hormone (LH), Follicle Stimulating Hormone (FSH),Estradiol (E 2) were detected by ELISA, and the protein expressions of Gonadotropin-releasing Hormone (GnRH) and Kisspeptin in hypothalamus were detected by Western Blot.Results:
Compared with the model group, the levels of LH and E 2 of the low, medium and high dose group of Jiuwei Chushi Decoction were significantly decreased ( P<0.05), while the FSH level was significantly increased ( P<0.05). The relative protein expression of GnRH (0.657±0.110, 0.536±0.152 vs. 0.912±0.219) and Kisspeptin (0.508±0.035,0.347±0.073 vs. 0.659±0.030) in the medium and high dose group of Jiuwei Chushi Decoction was lower than that of model group.Conclusion:
Jiuwei Chushi Decoction could affect hypothalamic Kisspeptin protein expression, inhibite hypothalamic GnRH expression, and decrease LH and E 2 levels in the serum of CPP rats.
