Abstract
In practical application of the idea of ideal postoperative essential amino acid ratio, that ofth e adult is more important than that of young (growing period). In this postoperative requirement of essential amino acid was studied in adult rats subjected to third degree of burn covering 20% of body surface.(1) Recovery from the burn was more rapid in growing rats (2 weeks) than in adult (3 weeks). The weight loss in the postoperative period continued for 1 week in growing rats and for 3 weeks in adult. The disturbance in metabolism due to surgical intervention was more marked in adult rats than in growing rats.(2) In adult rats, postoperative weight loss at 3 weeks was 20g in those fed 12g of 10% casein diet with 0.10g of glycine per day, and 9g in those fed 12g of 10% cesein diet with 0.6g of lysine.(3) The optimal postoperative requirement of lysine in adult rats was 2 times as much as that in normal metabolic state.
