The activity of bilirubin UDP-glucuronyltransferase in liver tissue was increased 1.5-fold after 90 min of secretion administration (4 i.u./h per kg body wt.) in anaesthetized Wistar rats biopsied half-hourly over a period of 2 h. In unanaesthetized R/A Wistar rats, activities of liver enzymes were assayed after administration secretin for 1 h. Bilirubin UDP-glycosyltransferase activities and cytochrome P-450 concentration were increased, but p-nitrophenol UDP-glucuronyltransferase and UDP-glucose dehydrogenase activities remained unchanged.
