摘要
To examine the effect of mifepristone compound (mifepristone + anor- drin) on estrogen receptor (ER) and progesterone receptor (PR) in early pregnancy decidua. Materials & Methods A Controlled study was carried out among 60 normal early pregnant volunteers (≤49d) in the department of obstetric and gynecology of Peking Union Medical Hospital. The concentrations of ER and PR were measured by radio- ligand and were compared with the control subjects after oral administration of mifepristone or mifepristone compound in different doses. Results The concentration of PR decreased while that of ER increased significantly in the decidua from all subjects administrated with mifepristone compound. We also found the concentration of EcR in Group 5 (mifepristone 30 mg + AF-53 5 mg) was the highest among 6 groups. The compound may be in favor of estrogen's action on endometrium. Conclusion The results indicate that mifepristone compound with AF- 53 has a coordi- nated function and can change the proportion of PR and ER. Hence, it can facilitate abortion. The compound dose of mifepristone 30 mg + AF-53 5mg is in favor of the endometrium recovering.
