摘要:

目的:探讨植物甾醇酯和葛根素联合使用对肥胖小鼠的减肥作用。方法:饲喂高脂饲料建立小鼠肥胖模型,将肥胖小鼠按体质量分为5 组(肥胖模型组、植物甾醇酯组、葛根素组、植物甾醇酯和葛根素联合组、奥利司他组),每组10 只,连续灌胃6 周。观察药物干预后小鼠体质量、摄食量、肥胖指数(Lee’s指数)、脂肪系数,血清总胆固醇(total cholestetol,TC)、甘油三酯(triglyceride,TG)、低密度脂蛋白胆固醇(low densitylipoprotein cholesterol,LDL-C)、高密度脂蛋白胆固醇(high density lipoprotein cholesterol,HDL-C)水平,脂肪细胞数量和大小、肝脏病变的情况。结果:与肥胖模型组相比,植物甾醇酯组、葛根素组、植物甾醇酯和葛根素联合组小鼠体质量分别降低5.41%、6.98%、12.50%;Lee’s指数分别降低3.41%、3.26%、6.25%;脂肪系数分别降低19.88%、27.41%、30.42%。3 组血清TC、TG、LDL-C水平均低于肥胖模型组,其中植物甾醇酯和葛根素联合组降幅最大,分别为21.40%、37.50%、30.43%。植物甾醇酯和葛根素联合组小鼠的脂肪细胞直径变小、数量增多、肝脏脂肪性病变得到缓解。结论:植物甾醇酯和葛根素都能抑制小鼠肥胖,其中两者联合使用时减肥效果最好。

Abstract:

Purpose: To study the weight loss effect of phytosterol ester and puerarin in obese mice. Methods: An obese
mouse model was established by feeding high fat diet, and then the obese mice were divided into five groups, including
model group, phytosterol ester group, puerarin group, phytosterol ester plus puerarin group, orlistat tablet group (10 mice per
group). The treatments by gavage lasted for six weeks. Then, body weight, food intake, obese index, fat index, serum total
cholestetol (TC), serum triglyceride (TG), low density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol
(HDL-C), the number and diameter of fat cells and liver lesions were measured. Results: Compared with the model group,
body weight in the mice from phytosterol ester group, puerarin group and combined treatment group were respectively
decreased by 5.41%, 6.98% and 12.50%. Obese indexes were respectively decreased by 3.41%, 3.26% and 6.25%. Fat
indexes were respectively decreased by 19.88%, 27.41% and 30.42%. The serum levels of TC, TG and LDL-C of the groups
treated with phytosterol ester and/or puerarin decreased compared to the model group, and the combined treatment group
showed the largest decline in the three serum lipid parameters by 21.40%, 37.50% and 30.43%, respectively. The number of
fat cells in the combined treatment group was increased, and liver fatty lesion was also alleviated. Conclusion: Phytosterol
ester and puerarin have weight-reducing effects on obese mice, especially when used in combination.
