title: [Experimental study on the inhibitory effect of Carboxymethyl Pachymaram on hepatitis B virus expression from transfected cells].
abstract: OBJECTIVE
  To observe the anti-HBV activity of Carboxymethyl Pachymaram (CMP) on the culturing of 2.2.15 cell line.
  
  
  METHODS
  Concentrations of 20.0 g/L, 12.0 g/L, 6.0 g/L, 3.0 g/L, 1.5 g/L of CMP were used to evaluate its toxicity to the cell line and the inhibition rates of the secretion of HBsAg and HBeAg in the cultured 2.2.15 cell line.
  
  
  RESULTS
  Experiments showed that the mean half toxicity concentration of CMP for 2.2.15 cell line was 13.6 g/L and concentration for 50% inhibition of the secretion of HBsAg and HBeAg were 4.45 g/L, 5.61 g/L and TI were 3.06 and 2.42. CMP showed stronger effect on anti-HBV than aciclovir.
  
  
  CONCLUSIONS
  CMP has good inhibitory effect on the secretion of HBsAg and HBeAg on cultured cell line 2.2.15.
