RESUMO
Objective To assess the effects of Jinghou Zengzhi Recipe(JHZZR),a Chinese prescription with the action of tonifying Qi and blood ,on the ovary apoptosis and expression of Bim in ovarian granulosa cells (GCs) of controlled ovarian hyperstimulation(COH) rats , and analyze the possible therapeutic mechanism. Methods A model of COH rats were prepaered and 30 female SD rats were randomly divided into 5 groups , including control group,positive control group,low,medium and high concentration group in six rats in each group. The apoptosis index(AI)in ovarian GCs were detected by TUNEL ,and the expression of Bim by qPCR. Results The AI of ovarian GCs in high and medium concentration group were obviously lower(P 0.05)comparing with control group. The mRNA levels of Bim were lower(P0.05)during the three concentration groups in Bim mRNA. Conclusion JHZZR can inhibit the ovarian GCs apoptosis of COH rats through decreasing the expression of Bim mRNA ,which improve the quality of ovarian follicle.
RESUMO
Objective To assess the effects of Jinghou Zengzhi Recipe ,a Chinese prescription with the action of tonifying Qi and blood,on the expressions of Bcl-2,Bax and Caspase3 in ovarian granulosa cells of con-trolled ovarian hyperstimulation(COH)mice. Methods A model of COH mice was prepared and 30 female KM mice were divided into blank group,model group and treatment group. The expressions of Bcl-2,Bax and Cas-pase3 were detected by Real-time Quantitative PCR and Western Blot. Results The mRNA and protein levels of Bax and Caspase3 were lower(P<0.05),while the protein levels of Bcl-2 were significantly higher(P<0.05)in the treatment group than those in the model group. There was no significant differences between the treatment group and blank group in the mRNA and proteins. Conclusion Jinghou Zengzhi Recipe can inhibit the ovarian granulo-sa cellular apoptosis of COH mice through increasing the expression of Bcl-2 protein as well as decreasing the ex-pressions of Bax and Caspase3 mRNA and proteins to nearly the natural level,which improves the quality of ovari-an follicle.
