脓毒症时基本代谢变化一般是大量的和不可逆的骨骼肌蛋白质水解。大量研究表明,支链氨基酸(BCAA)具有抗分解代谢的性质,可被肌肉氧化,在蛋白质周转中,起调节作用,有限制肌肉蛋白质降解和促进蛋白质合成的作用。本研究是在脓毒症动物模型中比较输入支链氨基酸含量不同的营养液时,蛋白质降解的程度。用豚鼠(475- Essential metabolic changes in sepsis are generally massive and irreversible proteolysis of skeletal muscle. Numerous studies have shown that branched-chain amino acids (BCAA) have anti-catabolic properties, can be oxidized by muscle, play a regulatory role in protein turnover, have the effect of limiting muscle protein degradation and promoting protein synthesis. In this study, we compared the extent of protein degradation in animal models of sepsis when comparing nutrient solutions with different branched chain amino acids. Guinea pigs (475-
