Objective:
To explore the Kidney-tonifying and abortion preventing effect of Shou Tai Wan (STW) by different extration methods on the SD Rats' abortion model.
Methods:
Applied hydroxycarbamide and mifepristone (RU-486) to establish the abortion model of corpus luteum inhibition due to Kidney deficiency (disease-syndorme combination model) on SD, rats. Treated the model rats with STW formula. Observed the uterus condition and recorded the embryo number and the miscarriage rate of each rat. 4 kinds of extractions including water extract of STW (A liquid), alcohol extract of STW (B liquid), after the ethanol water extract residue of STW (C liquid) and B + C liquid. Visual observed the uterine lesions embryos and calculated obortion rate. Used chemluninescence methed to cheek the serum estradiol (E2) and progesterone (P) level. Used quantitative RT-PCR (qRT-PCR) to analyze the different of the PR mRNR between the model group and the treated group.
Results:
Compared with the model group, the abortion rate of B + C liquid was greatly deduced and the embryo number of B + C liquid group, the E2 and P levels were obviously increased in the treated groups.
Conclusion:
STW (B + C) has the best effect of tonifying the kidney and preventing abortion.
