作者研究大鼠低热卡和高热卡喂养在实验性烧伤后减少自体蛋白分解代谢的作用。材料和方法22只雄性大鼠,在戊巴比妥钠麻醉下作空肠造口术,经4天恢复期后测定体重。17只鼠于戊巴比妥钠麻醉后作背部20～25％体表面积的烧伤。烧伤鼠随机分成三组,空肠内用输液泵给予等容量的喂养液。一组为生理盐水;一组为要素饮食,每天按体重给热卡320Kcal/kg,内含晶体氨基酸13.4g/kg;另一组给热卡105Kcal/kg,含晶体氨基酸4.5g/kg,喂养2
The authors investigated the effect of low calorie and high calorie card feeding in rats on reducing autoprotein catabolism after experimental burn. MATERIALS AND METHODS Twenty-two male rats underwent jejunostomy under sodium pentobarbital anesthesia. Body weights were measured after a 4-day recovery period. 17 rats were anesthetized with sodium pentobarbital for 20 to 25% of the body surface area of the burn. Burn rats were randomly divided into three groups, the jejunum with an infusion pump to give equal volume of feed solution. One group is physiological saline; one group is the elemental diet, giving 320Kcal / kg of calories per day according to body weight, containing 13.4g / kg of crystalline amino acids; the other group giving 105Kcal / kg of calories, containing 4.5g / kg of crystalline amino acids 2
