The total cholesterol, triglyceride level in the liver were showed tendency of increase with increasing of P/S ratios. Bile acid excretion in the fecal increased with increasing of P/S ratios. The value of TBA in the serum and liver were increased in proportion to the amount of polyunsaturated fatty acid. The liver fatty acid of coconut-fed group showed larger variation than fatty acid of the cocount oil. The fat chang of sunflower oil diet in the liver showed the largest change.
