Abstract:
OBJECTIVE: To investigate the effects of Yinchen Shufu Decoction on hepatocyte apoptosis and the expression of its apoptosis-regulating gene Bcl-2 and Bax in Yin-jaundice rats. METHODS: Forty-eight rats were divided randomly into 4 groups: the normal control group, Yin-jaundice model group, Yang-jaundice model group, Yinchen Shufu Decoction treatment group. The TUNEL assay and the immunohistochemistry assay were used to detect the apoptosis of hepatocytes and the expression of Bcl-2 and Bax in hepatocytes respectively. RESULTS: The rate of apoptosis cells in Yin-jaundice model group was higher significantly than that in Yang-jaundice model group and normal control group (P<0.01), the expression of Bcl-2 in Yinchen Shufu Decoction treatment group was higher significantly than that in Yin-jaundice model group (P<0.01 or P<0.05), and the expression of Bax in it was lower significantly than that in Ying-jaundice model group (P<0.01 or P<0.05). CONCLUSION: Yinchen Shufu Decoction can prevent hepatocyte apoptosis perhaps by up-regulating the expression of Bcl-2 and down-regulating the expression of Bax. It is one of the mechanisms of its treatment on Yin-jaundice.
