This study was conducted to investigate the influence of laminaran from Eisenia bicyclis on serum lipid composition of rats fed high fat and cholesterol diets. Fourty male Sprague-Dawley rats weighing $70{\pm}2.5g$ of 4 weeks old were fed experimental diets for 6 weeks with high fat diet consisting of basal diet plus cholesterol (1%) and lard (10%) for the inducement of hyperlipidemia. The effect of laminaran supplements via drinking waters on serum lipid composition of rat were investigated for 5 weeks by administration of experimental diet group fed basal diet only as normal group, control group fed high fat diet, LL group fed high fat diet plus 0.25% laminaran containing water, and LH group fed high fat diet plus 0.5% laminaran containing water, respectively. As a results of experiments, it was found that LL and LH groups showed significant (p<0.05) decrease in body weight gain and liver weight as compared with control and it may caused by decreased FER. The weight of cecum and adipose tissue (EFP) of LL group showed a significantly (p<0.05) decreased patterns compared with control. It was also found that LL and LH diet groups affects the intestinal length and transit time of rat as significantly (p<0.05) increased in length of intestine and decreased in transit time. In addition, LL and LH diet groups showed a dramatic decrease in triglyceride, total and LDL-cholesterol, and significant increase in HDL-cholesterol compared with control diet group, by which results in decreased in AI. These results indicate that crude laminaran from Eisenia bicyclis has a strong hyperlipidemic and hypercholesterolemic activities in rat fed high fat and cholesterol diet.
