The purpose of this study was to investigate the effect of dietary taurine supplementation on plasma and liver lipid concentrations and plasma and urine Ca, Mg, Se, Zn concentrations in alcohol-consuming (15% of energy/d) rats. Thirty-two male rats (Sprague-Dawley) were divided into 4 groups and fed experimental diets (non-alcohol+control diet, non-alcohol+taurine, alcohol+control diet, alcohol+taurine) for six weeks. The level of taurine supplementation was 1.5 g/100 g diet. There were no significant differences in the body weight gain and total calorie intake between the control and alcohol groups, but the food efficiency ratio was higher in the control group. The concentrations of plasma total cholesterol, triglyceride, and HDL-cholesterol were higher in the alcohol group, while the levels were apparently reduced in the groups fed taurine. Glutamate-oxaloacetate transaminase (GOT) and glutamate-pyruvate transaminase (GPT) activities were not significantly influenced by alcohol (15% of energy) consumption and dietary taurine supplementation. The plasma concentrations of Ca, Mg, Se, and Zn were not affected by alcohol consumption or dietary taurine supplementation. Only the urinary excretion of Se significantly increased by alcohol consumption, which was decreased by dietary taurine supplementation. These results indicate that taurine exerted some beneficial effects on hypocholesterlemia, hypotriglyceridemia and urinary Se excretion caused by alcohol consumption.
本研究的目的是调查在饮用酒精(占能量的15%/天)的大鼠中,膳食补充牛磺酸对血浆和肝脏脂质浓度以及血浆和尿液中钙、镁、硒、锌浓度的影响。将32只雄性大鼠(斯普拉格-道利大鼠)分为4组,并给予实验性饮食(非酒精+对照饮食、非酒精+牛磺酸、酒精+对照饮食、酒精+牛磺酸),持续六周。牛磺酸的补充水平为1.5 g/100 g饮食。对照组和酒精组之间的体重增加和总卡路里摄入量没有显著差异,但对照组的食物效率比更高。酒精组的血浆总胆固醇、甘油三酯和高密度脂蛋白胆固醇浓度较高,而在喂食牛磺酸的组中这些水平明显降低。谷氨酸草酰乙酸转氨酶(GOT)和谷氨酸丙酮酸转氨酶(GPT)活性不受酒精(占能量的15%)消耗和膳食补充牛磺酸的显著影响。血浆中钙、镁、硒和锌的浓度不受酒精消耗或膳食补充牛磺酸的影响。只有酒精消耗会使硒的尿排泄量显著增加,而膳食补充牛磺酸会使其减少。这些结果表明,牛磺酸对酒精消耗引起的低胆固醇血症、低甘油三酯血症和尿硒排泄具有一些有益作用。
