Effects of sea cucumber cerebroside and its long-chain base on lipid and glucose metabolism in obese mice / 浙江大学学报·医学版

<p><b>OBJECTIVE</b>To investigate the effect of sea cucumber cerebroside(SCC) and its long-chain base(LCB) on lipid and glucose metabolism in obese mice.</p><p><b>METHODS</b>The mouse obese model was established by feeding high fat diet. The mice were randomly assigned to 4 groups: control group, model group, SCC group and LCB group. After 4 weeks, the glucose tolerance test was undertaken. After 5 weeks, the body fat content, organic indexes, serum lipid level, glycemic index and liver lipid level were determined.</p><p><b>RESULTS</b>Compared with the model group, the glucose tolerance in the SCC group and LCB group was ameliorated significantly (P<0.01, P<0.05); glycemic index (P<0.01, P<0.01), the weight of adipose tissue (P<0.05, P<0.01) and the hepatic TG were reduced significantly (P<0.05, P<0.05).</p><p><b>CONCLUSION</b>Sea cucumber cerebroside and its long-chain base can improve the glucose and lipid metabolism in obese mice.</p>

Effect of sea cucumber cerebroside on lipid metabolism in fatty liver rats / 浙江大学学报·医学版

<p><b>OBJECTIVE</b>To investigate the effect of sea cucumber cerebroside (SCC) on the lipid metabolism in rats with orotic acid-induced fatty liver.</p><p><b>METHODS</b>The non-alcoholic fatty liver disease (NAFLD) model was established by adding orotic acid to the diets in rats. The rats were randomly assigned to four groups:control group, NAFLD group, NAFLD + low SCC group and NAFLD + high SCC group. After 10 days of feeding, the serum and hepatic lipid concentrations and the aminopherase activities were measured; the composition of hepatic fatty acids was also analyzed.</p><p><b>RESULT</b>The serum TC and TG levels reduced significantly in the NAFLD group as compared with the controls (P<0.05), while the sea cucumber cereborside feeding raised the serum lipid concentrations (P<0.05). The hepatic TC and TG levels dramatically increased in the NAFLD group in comparison with the controls (P<0.05, P<0.01), while the hepatic lipid accumulations decreased in both SCC groups (P<0.05, P<0.01). The ALT and AST activities in the NAFLD group increased markedly when compared with the controls (P<0.05, P <0.01), while the sea cucumber cerebroside feeding attenuated the hepatic injury levels (P<0.05, P<0.01). Compared with the control group, the stearoyl-CoA desaturase (SCD) activity increased significantly in the NAFLD group (P<0.05), but decreased in SCC groups (P<0.05).</p><p><b>CONCLUSION</b>Sea cucumber cerebroside can attenuate the rat fatty liver induced by orotic acid.</p>
