Liu-Shen-Wan, a traditional Chinese medicine, improves survival in sepsis induced by cecal ligation and puncture via reducing TNF-alpha levels, MDA content and enhancing macrophage phagocytosis.
Sepsis in humans is a difficult condition to treat and is often associated with a high mortality rate. Here, we investigated putative protective effects of Liu-Shen-Wan (LSW), a well-known Chinese formula used in treating infectious diseases, against polymicrobial sepsis induced by cecal ligation and puncture (CLP). The oral administration of LSW, at the first dose of 60 mg/kg and then 30 mg/kg every 12 h, significantly improved the survival of CLP mice during a 4-day observation period. ⋯ Moreover, LSW markedly enhanced clearance of intraperitoneal bacteria associated with the increasing count of peritoneal leukocytes and enhancing phagocytic activity of macrophages partly impaired at 24 h after CLP. In contrast, LSW lightly reduced IL-1 levels at 4 h and failed to improve deactivated respiratory burst activity of neutrophils at 24 h after CLP. Thus, LSW exerts protective effects against sepsis induced by CLP, mainly by reducing plasma TNF-alpha and MDA levels and enhancing peritoneal macrophage phagocytosis, suggesting that it is a potential agent in the prevention and treatment of sepsis.
