【Abstract】 Objective To investigate the expression of vascular endothelial growth factor(VEGF) and angiogenesis in endometriosis and it relationship with clinical pathogene-sis. Methods S-P immunohistochemical method was used to detect VEGF expression and MVD in Lesions in 50 cases of ovarian endometrioma ,endometrium in 21 cases of myoma and 10 cas-es of adenomyosis. Results The positive rate of VEGF in ovarian endometrioma was 13.69±4.32 in epithelium, 9.24±6.55 in stroma MVD (160±53/mm2 ) was higher in endometrioma than in eutopic endometrium of myoma and adenomyosis. The difference was significant(P< 0.05) .There was positive relation between MVD and VEGF positive rate.According to (r-AFS) stage,there were no significance in positive rate of VEGF and MVD between 15 cases of Stage Ⅰ-Ⅱ and 35 cases of Stage Ⅲ -Ⅳ groups (P >0.05) . No correlation was found in clinical stage of endometriosis. Conclusion Overexpression VEGF of endometriotic tissue may partici-pate in angiogenesis process. It could be a theoretical basis for the treatment of endometriosis by an-ti-angiogenesis.更多还原
