有文献论及TPN时小肠结构及功能受到影响,从而使绒毛长度减短,上皮细胞增生变慢,胰腺功能受到抑制等。由于肠腔内传递营养对维持胃肠道生理的完整性极为重要,许多学者认为经胃肠道营养较TPN更为合理、简便。本文旨在评价纤维素对肠结构功能的作用,并比较了肠道外和肠道营养对肠道形态学和功能产生的影响。同时还测定了作为肠功能指标的二胺氧化酶(DAO)的活性。作者取200g重雄性Wistar大鼠随机分成5组,均给予相同热卡每日80kcal。CE-2组喂给普通食料;LRD加纤维组喂给低残渣食
Literature on the TPN affect the structure and function of the small intestine, thereby reducing the length of villi, epithelial cell proliferation slowed down, pancreatic function is inhibited. As the intestine to pass nutrition to maintain the integrity of the gastrointestinal tract is extremely important, many scholars believe that gastrointestinal nutrition than TPN more reasonable and simple. This article aims to evaluate the effect of cellulose on intestinal structural function and to compare the effects of parenteral and enteral nutrition on intestinal morphology and function. The activity of diamine oxidase (DAO), an indicator of intestinal function, was also determined. The author take 200g heavy male Wistar rats were randomly divided into five groups were given the same heat card daily 80kcal. CE-2 group fed normal food; LRD plus fiber group fed low residue food
