[Effect of sinomenine on tumor necrosis factor-alpha and nuclear factor-kappaB in the heterotopic tissue in rats with endometriosis].

OBJECTIVE: To investigate the effect of sinomenine on the level of tumor necrosis factor-alpha (TNF-alpha) and nuclear factor-kappaB (NF-kappaB) and in the heterotopic tissue in rats with endometriosis. METHODS: The rats with endometriosis were divided into sinomenine lavage group, blank control group, model group and danazol group, and the levels of TNF-alpha and NF-kappaB in the heterotopic tissues of the rats were detected with immunohistochemistry. RESULTS: Sinomenine lavage and danazol treatment both significantly decreased the levels of levels of TNF-alpha and NF-kappaB in the heterotopic tissues of the rats as compared with the model group (P<0.05), and lesions were significantly smaller in sinomenine lavage group than in danazol group. CONCLUSION: Sinomenine can inhibit the production and activity of TNF-alpha and NF-kappaB to suppress the adhesion, implantation, infiltration and growth of the endometrial cells in the rat model of endometriosis.
