title: Plasmodium chabaudi-infection of mice: effects of chloroquine and mefloquine. Inhibition of ornithine decarboxylase activity.
abstract: Ornithine decarboxylase activity was inhibited in Plasmodium chabaudi-infected red cells of mice treated with chloroquine, mefloquine, primaquine and floxacrine. In vitro experiments on membrane-bound enzymes performed with intact P. chabaudi-infected red cells and corresponding ghost preparations showed a stimulation of NA+K+-ATP'ase and Ca2+Mg2+-ATP'ase activity in the presence of chloroquine, mefloquine and floxacrine.
