[Effect of immunostimulants on kidney tubule secretion of xenobiotics].

Excretion of cardiotrast (diotrast) was used to study tubular secretion of organic compounds in rats. Immunostimulants prodigiosin (0.05 mg/kg) and levamisole (10 mg/kg) injected subcutaneously three times every other day increased cardiotrast excretion. High levamisole dose (50 mg/kg), having no stimulating effect on the immunity, failed also to influence tubular cardiotrast transport. Possible mechanisms of immunostimulants' action on the tubular secretion of xenobiotics is discussed.
