Rats of the Donryu, Wistar, Fischer, and Sprague-Dawley strains were examined for the effects of choline deficiency on liver lipids, serum lipids, and serum ornithine carbamoyltransferase. The liver total lipid, triacylglycerol, cholesterol and phospholipid contents in the choline-deficient rats were significantly higher than those in choline-sufficient rats. The contents of total lipids and phospholipids in the liver of the Wistar and Fischer rats fed on a choline-deficient diet were signilicantly higher than those of the Donryu and Sprague-Dawley rats. The levels of triacylglycerol, cholesterol and phospholipids in the serum were significantly decreased by feeding with the choline-deficient diet. The serum ornithine carbamoyltransferase activity was increased in the Wistar and Fischer strains by feeding with the choline-deficient diet. The Wistar and Fischer strains were consequently the most sensitive to both lipid accumulation and liver lesions induced by the choline deficiency.
