title: Effects of aqueous extracts of Aconitum carmichaeli, Rhizoma bolbostemmatis, Phytolacca acinosa, Panax notoginseng and Gekko swinhonis Gūenther on Bel-7402 cells.
abstract: OBJECTIVE
  To investigate the anticancer activity of a chinese medical mixture, WRCP (warming and relieving Cold Phlegm), on hepatocarcinoma Bel-7402 cells.
  
  
  METHODS
  Fingerprints of WRCP, which were composed of aqueous extracts of Aconitum carmichaeli, Rhizoma bolbostemmatis, Phytolacca acinosa, Panax notoginseng and Gekko swinhonis Guenther, and aconitine, which could be isolated from Aconitum carmichaeli and have the potential toxicity, were identified by high pressure liquid chromatography. Bel-7402 cells were grown in the presence of WRCP, As(2)O(3) or all-trans-retinoic acid (ATRA). Cell proliferation and viability were determined by trypan blue stain. Apoptosis and cell cycle of Bel-7402 cells were detected by flow cytometry. Morphologic and ultrastructural variations were determined under optic and electronic microscopy. The secretion of alpha-fetoprotein and albumin was detected by radioimmunoassay.
  
  
  RESULTS
  The average quality of aconitine is 1.15 +/- 0.10 microg per 7.5 g extracts. WRCP could suppress the proliferation and viability of Bel-7402 cells. The percentage of apoptosis cells and S phase cells increased on WRCP-treated cells. Treated with WRCP, Bel-7402 cells showed ultrastructural features of differentiation. The alpha-fetoprotein secretion decreased while the albumin secretion increased (P < 0.001, P < 0.001, respectively) markedly in WRCP-treated cells.
  
  
  CONCLUSIONS
  WRCP can affect the proliferation, differentiation and apoptosis of Bel-7402 cells. It can arrest cells in S phase and has strong cytotoxicity to Bel-7402 cells.
