In order to address this issue, male C57BL/6 mice were treated i.p. with 5 mg/kg diethylnitrosamine when 15 days old and the histolÃ3gica! features of induced hepatocellular neoplasms were assessed at ...
The expression of four cytochrome (cyt.) P-450 ¡soenzymeshas been studied in preneoplastic and neoplastic lesions during the course of nitrosamine-induced hepatocarcinogenesis in the female Wistar rat. Fol lowing exposure to diethylnitrosamine (50 or 100 ppm in the drinking water) for 10 days, animals were taken sequentially, and the livers were analyzed for the evolution of adenosine triphosp...
233 SD rats weighing 100 approximately 120 g were divided randomly into 6 groups.
