To investigate the effect of sea cucumber cerebroside (SCC) on the lipid metabolism in rats with orotic acid-induced fatty liver.
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.
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).
Sea cucumber cerebroside can attenuate the rat fatty liver induced by orotic acid.
研究海参脑苷脂(SCC)对乳清酸诱导的大鼠脂肪肝脂质代谢的影响。
通过在大鼠饮食中添加乳清酸建立非酒精性脂肪性肝病(NAFLD)模型。将大鼠随机分为四组:对照组、NAFLD组、NAFLD + 低剂量SCC组和NAFLD + 高剂量SCC组。喂养10天后,测量血清和肝脏脂质浓度以及转氨酶活性;同时分析肝脏脂肪酸组成。
与对照组相比,NAFLD组血清总胆固醇(TC)和甘油三酯(TG)水平显著降低(P<0.05),而给予海参脑苷脂后血清脂质浓度升高(P<0.05)。与对照组相比,NAFLD组肝脏TC和TG水平显著升高(P<0.05,P<0.01),而两个SCC组肝脏脂质蓄积均减少(P<0.05,P<0.01)。与对照组相比,NAFLD组丙氨酸氨基转移酶(ALT)和天冬氨酸氨基转移酶(AST)活性显著升高(P<0.05,P<0.01),而给予海参脑苷脂可减轻肝脏损伤程度(P<0.05,P<0.01)。与对照组相比,NAFLD组硬脂酰辅酶A去饱和酶(SCD)活性显著升高(P<0.05),而在SCC组中降低(P<0.05)。
海参脑苷脂可减轻乳清酸诱导的大鼠脂肪肝。
