[Experimental filariasis in Proechimys oris by Dipetalonema dessetae: 4. Effect of parasitism on protein and tissue binding of diethylcarbamazine].
Several groups of control and filaria-infected Rodents were treated by radio-labelled diethylcarbamazine in order to study the effect of parasitism on the protein binding and tissue distribution of the drug. These studies were performed using equilibrium dialysis, chromatography and autoradiography. The plasmatic protein concentrations were lower in the group of infected Rodents, due to a decrease of albumin. The binding rate depended on the electrophoretic fractions, but remained low and unaffected by parasitism. The radioactivity of DEC and its metabolites appeared very quickly in the tissues, particularly in infected Rodents. This was due to the fact that the already rapid intestinal absorption and diffusion were enhanced by filariasis.
