Abstract
This study was designed to evaluate the anti hypercholesterolemic effect in either soybean oil or lard containing hypercholesterol diet in rats. Rats were fed, ad libitum, for 5 weeks with diets containing 0, 5, 10% of L.edodes in either soybean oil or lard with 1% exogenous cholesterol. Forty-two male sprague-dawley rats weighing 71.6$\pm$8.1g were divided into 6 groups. The results of this study were summairzed as follows: 1. Weight gain, total feed intake, feed intake efficiency ratio, total calorie intake and calorie efficiency ratio during five weeks showed significant difference among groups. The lowest value was found in soybean oil ＋ L.edodes-free group and the highest value was found in lard ＋ L.edodes-free group. The weight of organs were significantly higher in lard groups than soybean oil groups. 2. The contents of serum triglyceride showed significant difference kinds of lipids. It tended to be lower soybean oil groups than lard groups. It was difference with dietary L.edodes levels in soybean oil groups. The contents of total serum cholesterol showed significant difference by kinds of lipids, it was lower soybean oil groups than lard groups. But it was not differ with dietary L.edodes levels in soybean oil groups. 3. The contents of total liver cholesterol showed no difference kinds of lipids. And it was lower in soybean oil groups than lard groups. This result showed that the soybean oil decreased the contents of total liver cholesterol.
