ABSTRACT

Objective To explore the mechanisms on the damage in fetus liver,kidney and brain with administration of mifepristone and mesoproseol.Methods 17 specimens were obtained from the women who volunteered to terminate their pregnancy during 10～28 weeks.According to the fetus weight,they were divided into 3 groups.Immunohistochemistery was induced to investigate the expressions of pur-?,HSP70.Results The expressions of pur-? and HSP70 could be observed in both the treatment group and the control group.pur-? and HSP70 are the targets in detecting the damage of DNA.But pur-? was more sensitive than HSP70.The damage on group Ⅱ is the strongest.Conclusion Mifepristone can lead to the damage to lover,kidney and brain in mid-pregnancy.Its damage will be reducing as the growing of fetus.
