title: Effect of fangchinoline in murine models of multiple organ dysfunction syndrome and septic shock.
abstract: OBJECTIVE
  To study the effect of the alkaloid fangchinoline on zymosan-induced multiple organ dysfunction syndrome (MODS) and Escherichia coli (E. coli)-induced septic shock.
  
  
  METHODS
  Male ICR mice were used. Macrophages were isolated from peritoneal cavity for in vitro study.
  
  
  METHODS
  Fangchinoline was administered i.p. at a dose of 1 or 5 mg/kg into the mice.
  
  
  METHODS
  MODS was induced by intraperitoneal (i.p.) injection of zymosan at a dose 1.0 or 0.8/g b.w. E. coli-induced septic shock was provoked by i.p. inoculation of 5 x 10(8) bacterial cells into mice. TNF-alpha in serum and supernatants from peritoneal macrophages was detected by the use of L-929 cell cytotoxic assay. Alternative pathway (AP) complement activity was determined by hemolytic assay.
  
  
  RESULTS
  Fangchinoline increased the survival rate in lethal MODS and septic shock. The alkaloid prevented the loss of body weight and liver enlargement in MODS and suppressed serum tumor necrosis factor-alpha (TNF-alpha) accumulation in MODS and septic shock.
  
  
  CONCLUSIONS
  The result suggest that fangchinoline due mainly to its ability to downregulate TNF-alpha production might have protective effect in murine models of zymosan-induced MODS and E. coli-induced septic shock.
