title: [Influence of glutamic acid, histidine and arginine on dietary intake. Chemical structure and body mass composition of rats].
abstract: 100 male rats, aged 30 +/- 1 days were investigated by means of 28 days study. The influence of the supplementation of glutaminic acid, histidine and arginine to the diet on dietary intake, weight gain and chemical composition was determined. It was casein that was used as the source of protein. We investigated the application of 4 kinds of diet during each experiment and the composition of the diets was based on the Miller-Bend non-protein diet model. The casein control diet contained 20g of casein per 100 g of diet. The diet with the supplementation of glutaminic acid contained 15 g of casein and 5 g of glutaminic acid per 100 g of diet. The histidine diet contained 15 g casein and 5 g of histidine per 100 g of diet. The arginine diet contained 15 g of casein and 5 g arginine per 100 g of diet. The addition of glutaminic acid, histidine and arginine to the diet caused the substantial decrease of diet intake weight gain and its ingredients. The addition of histidine to the diet reduced the nitrogen/total water contain ratio. This resulted in the inhibition of the chemical maturation of rat tissue and simultaneously decreased the percentage contain of fat in rat body.
