Effect of Mifepristone and Anordrin Compound on Levels of Estrogen and Progesterone Receptor mRNAs in Human Decidua of Early Pregnancy

To provide the theoretical fundation for the further clinical application of mifepristone and anordrin compound. Materials Methods Ribonuclease protection assay was used for the detection and quantitation of estrogen and progesterone receptor mRNAs in human decidua from the termination of early pregnancy.Three groups, each of which had 6～8 cases, were studied. Results Compared to the normal control group, estrogen and progesterone receptor mRNAs increased significantly (P0.05) in the mifepristone group, whereas the changes in the group administrated mifepristone compound which contains anordrin were not obvious. Conclusions The result suggests that with the similar clinical effect, mifepristone compound has less side effect on the patients, thus being more suitable for the anti early pregnancy drug.
