title: Reducing effects of rodent malaria on hepatic carcinogenesis induced by dietary aflatoxin B1.
abstract: The present study was undertaken to evaluate the effects of Plasmodium berghei infection on the development of liver tumors induced in male Buffalo rats by aflatoxin B1 (AFB1). Intraperitoneal (i.p.) injection of 10(6) parasitized red blood cells (pRBC) into the rat 12 days prior to administration of 2 ppm dietary AFB1 for 10 weeks diminished hepatocellular carcinoma (HCC) induction compared to that observed in rats given AFB1 alone at weeks 60-82. No animals in a control group developed HCC lesions, while only 1 of 22 rats treated with P. berghei alone developed a neoplastic nodule at week 82. These data suggest a reducing effect of P. berghei on the development of liver tumors induced by AFB1 in male Buffalo rats.
