ABSTRACT
Objective To investigate and compare the expression of decidual LIF between early pregnancy and mifepristone induced abortion.Methods By immunohistochemical analysis,the expressions of decidual LIF were detected with quantitative analysis to the grey degree of immunohistochemical staining for LIF by HPIAS-1000 and collected the pictures by JPEG system.Results The grey degree of immunohistochemical staining for LIF of decidual cells in grandular epithelial cells is higher than that in stroma cells(P0.05).The expressions of LIF in grandular epithelial cells and stroma cells can be detected in both plasma and nucleus.Conclusions The expressions of decidual LIF are different in locations.Further study is needed for the mechanism of mifepristone induced abortion.
