Abstract:
Aim To investigate the influence of Tanshinone ⅡA on cytokine secreted by kuppfer cells via LPS stimulation,and explore its mechanism of therapying chronic hepatic disease. Methods The liver cell and kupffer cells were isolated and the model of liver cell injuries was made induced by LPS and D-GlaN, and the effects of TanshinoneⅡA was observed on the injuries of liver cell induced by lipopoly-saccharide(LPS) and D-Galactosamine(D-GlaN). Cytokine were released secreted by kupffer cells through LPS stimulation and the contents of TNF-?,IL-6,IL-8 were determined by radio-immunoassay. The hepatocyte morphological character was observed by HE stain,the expressions of TNF-?、CD14、iNOS、eNOS in kupffer cell were explored by immunohistochemical, double-decker chamber was used for observing the damage of hepatocyte caused by cytokine secreted by kupffer via LPS stimulation. Results Tanshinone ⅡA could restore the injury of liver cell induced by D-GlaN and LPS, the levels of ALT、MAO、LDH-L、GSH-S and contents of MDA were significantly reduce.It could inhibit TNF-? IL-8 secreted by kupffer cells through LPS stimulation ,and the expressions of TNF-?、CD14 Inos、eNOS in kupffer cell through LPS stimulation were inhibited. Blocking injuries of the inflammatory cytokine release excessive on liver cell, it hadn′t the protect action on liver cell damage suffer from inflammatory cytokine.Conclusion The mechanism of Tanshinon ⅡA of blocking liver cell injuries induced by D-GlaN and LPS may be correlation with inhibiting the excessive cytokine by kupffer cells
