Abstract:

30 patients were treated endometrium because bleeding after mifepristone induced abortion.The sections of abstracted endometra were showed by im m unocytochemical method.The abstracted tissue contained normal endometriu m ,remaining decidua and a small amount of chorion villi.hPLlocated in trophoblasts of remaining chorion villi,trophoblastic pieces and trophoblastic bulbs of the endometrium and decidua.There were a lot of hPLpositive extravillous trophoblastsin remaining decidua. The trophoblastic bulbs and extravillous trophoblasts could transfer to distant placees and become cancer cells.To show hPLpositive cellin abstracted tissues would help us to detecttrophoblastic proliferating and trophoblastic cancer at the righttime.

Key words: human placentallactogen, endometrium, trophoblast, mifepristone
