ABSTRACT
The effect of Lycii Cortex on the PCOS rat model and the mechanism of action were investigated in the present study. The PCOS rat model was induced with Poretsky methods. Then the rats were randomly divided into four groups the model group, melbine group (0.45 g x kg(-1)), low (2.5 g x kg(-1) and high (10 g x kg(-1)) dosage group of Lycii Cortex. The animals were orally administrated with the drugs for 14 days. In addition, another control group was added in this study. The rats were weighted before and after drug treatment. After 14 days treatment, oestrous cycle of rats were detected; blood serum was separated to determine T and FINS and rat's uteri were isolated. The mRNA and protein (total and phosphorylated) expressions of PI3K and PKB in uteri were measured with Real-time RT-PCR and Western blot, respectively. Compared with the control rats, the body weight gain and serum level of T and FINS were significantly increased. While, the mRNA and protein (phosphorylated) levels of PI3K and PKB were markedly decreased in PCOS group. Lycii Cortex treatment significantly decreased the body weight gain and serum level of T and FINS in a dose-dependant manner. It also markedly increased the mRNA and protein (phosphorylated) expressions of PI3K and PKB. Meanwhile, the melbine treatment also showed the curative effect. Lycii Cortex can relieve the symptoms of PCOS and the mechanism might be related to PI3K/PKB pathway.
