Abstract

Rats were pretreated with allyl alcohol, carbon tetrachloride or bromobenzene to induce histopathological evidence of periportal, midzonal to centrilobular, and centrilobular hepatic necrosis. The amount of various drug metabolizing enzyme systems present after necrosis was determined indirectly by measuring the rate of metabolism for specific substrates in vitro. The chemically induced hepatocellular injury of these toxins produced variable but significant alterations in hepatic drug metabolism. The changes in enzymatic activity related well with the area of the lesion produced by each toxin. Thus, these hepatotoxins appear to be useful as probes to determine the hepatolobular distribution ..
