[Inhibitory effects of Sanleng pellet on angiogenesis of endometriosis in rats].

OBJECTIVE: To investigate the effect of Sanleng pellet on angiogenesis of endometriosis in SD rats. METHOD: The rat model of endometriosis were treated with Sanleng pellet. Observe microvessels density by immunohistochemical test as well as the expression of vascular endothelial growth factor and tumor necrosis factor-alpha in ectopic endometriotic tissue by immunohistochemical test and RT-PCR. RESULT: Sanleng pellet can reduce MVD, and inhibit the level of protein and mRNA of vascular endothelial growth factor and TNF-alpha in ectopic endometriotic tissue. CONCLUSION: Sanleng pellet can reduce the degree of angiogenesis in the endometriosis rats, and its mechanism might be associated with inhibiting the expression of vascular endothelial growth factor and TNF-alpha in the heterotopic tissue.
