RESUMEN
Objective To study the mechanism of traditional Chinese medicine Compound Xueniaoting (CXNT) in treating glomerulus diseases with the main pathological changes of proliferation in mesangial cells. Methods CXNT and rat liver microsomes were incubated together, and then the incubated CXNT was added into cultured glomerular mesangial cells (GMC) in vitro. The proliferation of GMC was observed by MTT assay, the levels of interleukin-6 (IL-6) and endothelin-1 (ET-1) were determined by radioimmunoassay, and content of lactic dehydrogenase (LDH) was determined by velocity assay. ResultsCXNT (2, 4, 8 mg/mL) metobolized by rat liver microsomes could all inhibite the proliferation of GMC and production of IL-6 and ET-1 in a dose-dependent manner. Conclusion CXNT can inhibite the proliferation of GMC and restrain the secretion of IL-6 and ET-1, this function may be one of CXNT mechanisms in treating some mesangial proliferative glomerulonephritis.
