title: [Studies on pharmacokinetics of chloroquine in mice infected with chloroquine-resistant strain of Plasmodium berghei].
abstract: OBJECTIVE
  To compare the pharmacokinetic differences of chloroquine in normal mice and the mice infected with the N and the RC strains of Plasmodium berghei.
  
  
  METHODS
  The concentrations of chloroquine in the plasma of normal mice and the mice infected with the N or the RC strains of P. berghei were analyzed by reverse-phase HPLC. The pharmacokinetic parameters were measured with software 3P87.
  
  
  RESULTS
  The t1/2 beta value was significantly lower in the mice infected with the RC strain than in normal mice and the mice infected with the N strain(P < 0.05), however, there were no significant differences between the mice infected with the N strain and normal mice.
  
  
  CONCLUSIONS
  Elimination of chloroquine in the mice infected with the RC strain of P. berghei speed up significantly comparing with the mice infected with the N strain.
