title: The effect of a nutritional model of chronic liver injury on the hepatic glucuronidation of morphine in rats.
abstract: The effect of a choline-deficient diet on the hepatic glucuronidation of morphine was investigated using a rat perfused liver system. Rats fed a choline-deficient diet developed a fatty liver with minimal necrosis. Despite the morphological changes, neither hepatic extraction ratio (0.51 +/- 0.02 in control; 0.45 +/- 0.04 in the choline-deficient rats) nor intrinsic clearance (0.85 +/- 0.05 in control; 0.77 +/- 0.09 in choline-deficient rats) were affected by this injury model. This finding suggests that glucuronidation is relatively resistant to this chronic liver injury.
