饮食或饥饿会直接影响胃肠道功能.胃肠道是动力性器官,短期饥饿或完全胃肠外营养(TPN)会导致胃肠道萎缩.这提示胃肠道内营养素对维持胃肠道结构完整性起着十分重要的作用.液体要素饮食,作为一种基本的或支持性的营养物质来源在一组选择性的病人中使用,它在近端的小肠内几乎能够完全吸收.但是,这样的液体要素饮食,最终仍将会导致胃肠粘膜萎缩.就此现象有关专家进行了大量研究观察.Hwang等发现,要素膳或TPN营养液中加入一种非必要氨基酸——谷氨酰胺(GLN)会显著缓解胃肠粘
Diet or starvation can have a direct effect on gastrointestinal function, the gastrointestinal tract is a powered organ, and short-term starvation or total parenteral nutrition (TPN) leads to atrophy of the GI tract, suggesting that gastrointestinal endothelin may contribute to maintaining the structural integrity of the GI tract Plays a very important role Liquid elemental diet, used as a basic or supportive source of nutrients in a select group of patients, absorbs almost completely in the proximal small intestine However, such liquids Elemental diet, will eventually lead to gastrointestinal mucosal atrophy .Therefore, the phenomenon of the experts conducted a large number of research observations.Hwang found that elemental diet or TPN nutrient solution to add an unnecessary amino acid - glutamine (GLN) will be significant Relieve gastrointestinal sticky
