我国菰米对高脂膳食大鼠血脂及炎性因子的影响

目的探讨菰米对高脂膳食诱导脂代谢紊乱大鼠血脂及炎性因子水平的调控作用。方法44只雄性SD大鼠随机分为阴性对照组、高脂模型组、米面组和菰米组;以相应饲料连续喂养8w,测定各组大鼠体重、血清总胆固醇(TC)、甘油三酯(TG)、高密度脂蛋白胆固醇(HDL-C)、肿瘤坏死因子-α(TNF-α)和白细胞介素-6(IL-6)、高敏C反应蛋白(hs-CRP)等指标。结果与阴性对照组相比,高脂模型组和米面组大鼠的血清TC、TG显著上升,HDL-C显著降低;与高脂模型组和米面组比较,菰米组的血清TC、TG显著下降,HDL-C显著升高,TNF-α、hs-CRP显著下降。结论菰米具有降低脂代谢紊乱大鼠血脂的作用,并能改善高脂血症的低度炎性状态。

EFFECT OF CHINESE WILD RICE ON LIPID METABOLISM AND INFLAMMATORY FACTORS IN RATS FED WITH HIGH CHOLESTEROL DIETS

Objective To study the effect of Chinese wild rice diet on lipid metabolism in rats. Method Forty four male SD rats were divided into 4 groups:control group, high lipid group, white rice-flour group and Chinese wild rice group. All groups were given different experimental diets for 8 w and body weights, serum TC, TG, HDL-C, high sensitive C-reactive protein (hs-CRP), TNF-α and IL-6 were measured. Results The hyperlipidemic rat model was successfully induced. When compared with high lipid group and white rice-flour diet group, serum TG and TC contents were significantly decreased, and HDL-C significantly increased in the Chinese wild rice group. Moreover, Chinese wild rice group had lower contents of serum hs-CRP and TNF-α than those in high lipid group and white rice-flour group, but no effect on serum IL-6. Conclusion Chinese wild rice could improve lipid metabolism and low-grade inflammation of hyperlipidemic rats induced by high lipid diet.
