摘　　要： 采用大鼠喂养试验,研究乙基纤维素凝胶剂对包括心血管疾病高风险因子在内的动物营养生理功能的影响。根据大鼠营养生理数据表明,当饲料中含有乙基纤维素起酥油产品时,试验组大鼠的体重均低于对照组,且高剂量组大鼠体重最低。大鼠尿酸、游离脂肪酸含量显著低于空白对照组;高剂量组的白蛋白、球蛋白、总蛋白和瘦素指标明显高于其它组;大鼠血清中高密度脂蛋白含量、抗动脉粥样硬化指数AAI值均高于空白对照组(P<0.05),致动脉粥样硬化指数AI值和脂肪酶活力均明显低于空白对照组(P>0.05)。另一方面,高剂量组大鼠的血清葡萄糖、总胆固醇、甘油三酯、低密度脂蛋白、高密度脂蛋白与低密度脂蛋白的比值(HDL/LDL值)都同时高于其余各组。因此,以乙基纤维素为有机凝胶剂的起酥油产品对动物机体不会产生不良影响。 In this study, we examined the effect of ethyl cellulose as organogel on animal nutrition physiological function by the rat feeding test, including the high risk factor of cardiovascular disease. The results showed that rat body weight of experimental groups was lower than the control group, and the high dose group was the lowest. The data also showed the indexes of free fatty acid, uric acid were significantly lower than that of the control group. Compared with other groups, high does of ethyl cellulose increased the level of albumin, globulin, total protein and leptin of rat. In addition, the level of high density lipoprotein, AAI of anti atherogenic were higher than that of control group（P〈0.05）;both AI of atherogenic index and lipase activity were significantly lower than control group（P〈0.05）. On the other hand,high dose group rats have the higher level of serum glucose, total cholesterol, triglyceride, low density lipoprotein and the ratio of high density lipoprotein cholesterol and low density lipoprotein（HDL/LDL value） than other groups. With feed of ethyl cellulose shortenings, there was not adverse effects on rats.
