Abstract
The effect of enhanced cell replication induced by partial hepatectomy (PH) in aflatoxin B1 (AFB1)-induced hepatocarcinogenesis has been studied in rats of the inbred As2 strain. Animals were given 0.25 mg/kg body weight of AFB1 as a single intraperitoneal dose 24 h after PH. Non-hepatectomized animals given the same dose of AFB1 served as controls. Neoplastic nodules and hepatocellular carcinoma (HCC) were detected respectively in 100% and 90% of hepatectomized animals sacrificed between 55 and 65 weeks after AFB1 administration. None of the ten non-hepatectomized rats sacrificed at this time interval showed HCC or neoplastic nodules. On histochemical staining the tumour population was found to be heterogeneous. Thus PH resulted in enhancement of AFB1-induced hepatocarcinogenesis in rats of the AS2 strain.Entities:
