为明确口服谷胺酰胺对全腹照射后大鼠受损小肠的代谢、结构和功能的影响,作者将22只大鼠麻醉后置227 cGY/分剂量下照射4.41分钟,共1000cGY,以往研究证实此照射模型的10天死亡率为50%。照射后,将动物分成两组,A组喂给3%L-谷氨酰胺液,B组喂给3%L-甘氨酸液,两组所喂给的氮量相等。 In order to clarify the effect of oral administration of glutamine on the metabolism, structure and function of injured small intestine after whole abdominal irradiation, 22 rats were anesthetized and placed at a dose of 227 cGY / min for 4.41 minutes for a total of 1000 cGY. Previous studies confirmed The 10-day mortality of this irradiation model was 50%. After irradiation, the animals were divided into two groups: group A was fed 3% L-glutamine solution, group B was fed 3% L-glycine solution, and both groups were given equal amounts of nitrogen.
