Abstract
The effect of Japanese catfish Silurus asotus lipid intake on the lipid met abolism of male adult mice was determined by measuring the total cholestero l, triacylglycerol, phospholipid, and fatty acid content of plasma and live r. Mice were fed diets containing 5% lard, 5% Thai catfish oil, 5% Japanese catfish lipids, or 5% sardine lipids for 4 weeks. The arachidonic acid (20 :4n-6) content was highest in the livers of mice fed the Japanese catfish l ipid diet and docosahexaenoic acid (22:6n-3) content was higher in livers o f the Japanese catfish lipid and sardine lipid diet groups than those of th e lard and Thai catfish diet groups. However, no significant differences we re observed in the 22.6n-3 levels in either plasma or liver between the Jap anese catfish lipid and sardine lipid diet groups. Although the Japanese ca tfish lipid diet contains, by far, the highest cholesterol content (143 mg/ 100 g), there was no significant difference in the plasma cholesterol level s between the lard, Thai catfish oil and Japanese catfish lipid diet groups . However, the liver cholesterol levels of mice fed the Japanese catfish li pid diet were lower than those of mice fed the Thai catfish oil diet, and w ere similar to those of animals fed a sardine lipid diet. These results sug gest that Japanese catfish lipids are suitable components of the diet for i ngestion of 20.4n-6 and 22:6n-3, and for decreasing the cholesterol content of liver.
