脂肪（MCT）および高濃度分枝鎖アミノ酸を含有した成分栄養剤の侵襲下における効果

The effects of a new enteral diet (ED-9) that was mainly composed of BCAA enriched amino acids, MCT and maltose were examined. Rats were subjected to small bowel resection and were administered two different formula for 7 days. The animals were divided into the following four groups : Sham operation and ED-9 (Group A), sham operation and control diet (Elental) (Group B), small bowel resection and ED-9 (Group C), and small bowel resection and control diet (Group D). Body weight loss after operation was similar in both ED-9 and control diet groups. Nitrogen balance and uninary 3 Methy1-histidine excretion demonstrated that ED-9 tended to improve protein preservation. Rats given ED-9 showed elevated ketone bodies and plasma BCAA level but these levels were not extraordinarily high. In conclusion, the formula of enteral nutrition (ED-9) was as effective as Elental on postoperative nutrition in rats.
