Effects of Endometrial His morphology of Cu-IUD Wearing Rabbits by Treating with Nourishing Qi and Eliminating stasiS Method

Objective To explore the mechanism of nourishing qi and eliminating stasis method to treat endometrorrhagia caused by Cu-IUD. Methods In constrast with Indomethacin，we investigated the effects of endometrial superficial microvessel ,thrombosis and spiral artery of Cu-IUD wearing rabbits treating with nourishing qi and eliminating stasis method by olympus light microscope.Results In Cu-IUD wearing rabbits contrast group endometrial epithelia were shed， necrosis and infiltrated with a lot of inflammatory cells .Much constitution fragments , inflammatory cells and exudates were observed in uterine cavity .Endometrial small vessels were dilatalted and hyperemia .Interstitial was a little rarefaction,edema and infiltrated with a lot of inflammatory cells .The sum of endometrial superficial microvessel was increased .The hismorphologic change of each group of nourishing qi and eliminating stasis method was similar to the Indomethacin group :endometrial epithelia was minor injury with less inflammatory cells ,endometrial small vessels were occasionlly dilatalted and hyperemia，interstitial was a little tight with less inflammatory ceils .Conclusion Treated with nourishing qi and eliminating stasis method can decrease the inflammatory cells and exudation of endometrium and repair the damage of endometrium，wich indicate that endometrorrhagia caused by Cu-IUD can be cured effectively with nourishing qi and eliminating stasis method.
