了解红米对机体血脂及抗氧化系统的影响。方法:SD二级雄性大鼠30只,体重(g)180~220,随机分为两组,每组15只。实验组:普通大鼠饲料加30%红米粉;对照组:普通大鼠饲料加30%白米粉,连续喂养45天,喂养期间每天称进食量,每周测定体重,第46天取动脉血测定血清总胆固醇(TC)、甘油三酯(TG)、高密度脂蛋白胆固醇(HDL-C)、低密度脂蛋白胆固醇(LDL-C);血清谷胱甘肽过氧化物酶(GSH-Px)和超氧化物歧化酶(SOD)活性。结果:1.两组动物体重增长和日进食量无显著性差异。2.血脂比较:红米组HDL-C(mmol/L)0.72±0.11明显高于白米组0.70±0.05,P<0.05。TC、TG、LDL-C两组无明显差异。3.血清GSH-Px和SOD活性:红米组GSH-Px活性(U)114.09±4.78明显高于白米组109.45±15.07,P<0.01;红米组SOD活性(nU/ml血清)248.79±47.59明显高于白米组(210.84±32.09),P<0.05。讨论近年来大量研究表明,机体脂质代谢紊乱,抗氧化能力降低,氧化脂质产物增多是造成动脉硬化血管损伤的关键。随着年龄增加,人体内抗?
Understand the impact of red rice on body fat and antioxidant system. Methods: Thirty SD male rats weighing 180-220 were randomly divided into two groups (n = 15 each). The rats in the control group were fed with 30% red rice flour. The control group: ordinary rat feed plus 30% white rice flour was continuously fed for 45 days. The feeding amount was weighed every day and the body weight was measured weekly. The arterial blood was taken on the 46th day Serum total cholesterol (TC), triglyceride (TG), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), serum glutathione peroxidase (GSH-Px) And superoxide dismutase (SOD) activity. Results: 1. There was no significant difference in body weight gain and daily food intake between the two groups. 2. Blood lipids: Red rice group HDL-C (mmol / L) 0.72 ± 0.11 was significantly higher than the white rice group 0.70 ± 0.05, P <0.05. TC, TG, LDL-C no significant difference between the two groups. 3. Serum GSH-Px and SOD activity: red rice group GSH-Px activity (U) 114.09 ± 4.78 was significantly higher than the white rice group 109.45 ± 15.07, P <0.01; Red rice group SOD activity nU / ml serum) 248.79 ± 47.59 was significantly higher than the white rice group (210.84 ± 32.09), P <0.05. Discussion In recent years, a large number of studies have shown that the body lipid metabolism disorders, reduced antioxidant capacity, increased oxidation of lipid products is the key to cause atherosclerosis vascular injury. With age, the human body resistance?
