Objective:To study the anti-inflammatory mechanism of Qishe pill on stimulated macrophage.Method:Interferon-γ(IFN-γ) plus lipopolysaccharide(LPS) stimulated RAW 264.7 macrophage was used as inflammatory experimental model.Griess reaction for nitric oxide production and Western blot for protein expression examination were performed.Result:Qishe pill inhibited nitric oxide(NO) production in a dose-dependent manner without cytotoxicity.The protein expression of inducible nitric oxide synthase(iNOS) and cyclooxygenase(COX-2) were also suppressed by Qishe pill treatment.Furthermore
phosphorylation of extracellular signal-regulated kinase(ERK)
c-Jun NH2-terminal kinase(JNK) and p38 protein was markedly inhibited.Conclusion:Qishe pill suppressed over production of NO and iNOS expression via inhibition of phosphorylation of ERK
JNK and p38/MAPK(mitogen-activated protein kinas) activated signalling pathway partly.
