Objective: The aim of this study was to investigate the effects of ginsenoside Rg3 and ginsenoside Rg3 combined with cisplatinon the growth of nude mice cervical cancer, and to explore the possible mechanism of ginsenoside Rg3 and ginsenoside Rg3 combined with cisplatinin cells and molecules levels. The growth of human cervical cancer Hela cell, apoptosis of tumor cells , expression of CD31and PeNt were observed with optic microscope, radio-immunity immunological histo chemistry, terminal deoxynucleotidy transferase-mediated dUTP nick end labeling, and immunohistochemical staining. The purpose of this study is to provide a new way of medication to eure cervical cancer in clinic.

目的:本实验通过建立子宫颈癌裸鼠病理模型后,以此为研究对象,运用光镜、免疫组化及末端脱氧核苷酸转移酶介导的dUTP缺口末端标记技术,观察人参皂甙Rg3[20—Ginsenoside Rg3]和顺铂单独及二者联合应用对人宫颈癌Hela细胞裸鼠移植瘤生长的影响,重点研究肿瘤的生长、肿瘤细胞的凋亡及PCNA、CD31的表达情况,以期从细胞及分子水平揭示人参皂甙Rg3和顺铂单独及二者联合应用对人宫颈癌Hela细胞的作用机制,为临床上药物治疗与预防宫颈癌寻找更加完善的途径。
