To explore the part of inflammatory factors (cytokines) and Yishen Huoxue Xiezhuo (YSHXXZ) Decoction on the proliferation
of extracorporeal cultured
mesangial cells (MCs) in rats. Methods: The effects of
lipopolysaccharide (LPS) and interleukin 6 (IL 6) as stimulating factors, its action on the proliferation of rat MCs were investigated by using the technique of 3 H TdR incorporation. Meanwhile, adopting serum pharmacology assay, the medicated serum of rat, containing YSHXXZ decoction was extracted and its effects on the growth of MCs were also studied. Results: LPS and IL 6, in a dose dependent and time dependent manner, could markedly stimulate the MCS proliferation, while this stimulatory effects could be strongly antagonized by the serum containing YSHXXZ decoction. Conclusion: Mesangial cell is the main target cell of the action of YSHXXZ decoction, and the inhibition on MCs might be one of the mechanisms of the YSHXXZ decoction in preventing the progression of chronic glomerulonephritis.
