Microsomal cytochrome P450 and peroxisomal activity were studied in li
ver of rats I days after two-thirds hepatectomy or bile duct ligation
(BDL). Both surgical models decreased the hepatic microsomal cytochrom
e P450 content, but only cholestasis, produced by BDL, decreased the m
icrosomal metabolism of lauric acid and aminopyrine, peroxisomal fatty
acid beta-oxidation and catalase activity. The microsomal and peroxis
omal activities responded in a coordinate way to cholestasis and two-t
hirds hepatectomy. These results suggest a cause-effect relationship b
etween the microsomal cytochrome P450 and peroxisomal activity. Copyri
