Abstract:Objective: To make a study of the effect of Chaihu Shihuang soup on blood serum level TNF, IL-6 and IL-10 of severe acute pancratitis. Method: Sixty SAP cases were divided at random into treatment group and control group (30 cases each). The treatment group were given chai-hu-shi-huang-soup once a day; the control group were given Dachaihu soup once daily, with both treatment period for 7 days. The tumor necrosis factor-α (TNF-α), interleukin level 6 (IL-6) and 10 (IL-10 of both groups were determined before and after the treatment. We also had 30 healthy cases. Result: IL-10 level in both groups was lower than healthy group while TNF-α and IL-6 were higher than healthy group (P<0.01). After treatment, the treatment group‘s TNF-α, IL-6 level were comparatively lower than that in the control group (P<0.01), and IL-10 level were clearly higher than that of the control group (P<0.01), comparison of the treatment group before treatment (P<0.01). Conclusion: Chaihu Shihuang soup can significantly regulate cytokine and improve early recovery of SAP.
