title: [Protective effect of total flavonoids of fructus choerospondiatis on adriamycin-induced rat cardiac peroxidation].
abstract: OBJECTIVE
  To study the protection effect of total flavnoids of Fructus Choerospondiatis (TFFC) on rat cardiac muscle peroxidation in vitro and vivo.
  
  
  METHODS
  Adriamycin-induced peroxidation model on rat was adopted. Activities of LDH, AST and CK in rat's serum, activities of SOD, GSH-Px and content of MDA in rat cardiac muscle were determinated. Activity of LDH and content of MDA in cultured suckling rat cardiac cell were also determinated.
  
  
  RESULTS
  Compared with normal group, activities of LDH, AST, CK in serum and content of MDA in cardiac muscle on adriamycin group increased (P < 0.05, P < 0.001), activities of SOD, GSH-Px decreased in cardiac muscle (P < 0.001). Activity of LDH and content of MDA in cultured fluid of suckling rat cardiac cell were higher than that of normal group (P < 0.001). To various dosages TFFC groups, activity of LDH, AST, CK in serum and content of MDA in cardiac muscle decreased; activities of SOD and GSH-Px in cardiac muscle increased; activites of LDH and content of MDA in cultured fluid decreased (P < 0.01, P < 0.001).
  
  
  CONCLUSIONS
  TFFC can maintain the integrity of cytomembrane by scavenging free radicals and inhibiting lipid peroxidation, namely, TFFC has an effect of protecting cardiac muscle.
