[Intravenous alimentation of rats in renal failure]

Experiments on nephrectomized rats were made to compare the effect of oral and intravenous feeding on the degree of uremia and general status of the body. Intravenous feeding which included only essential amino acids as nitrogenous component or an insufficiently balanced mixture of essential amino acids and several replaceable amino acids (9.5% of energy value) did not produce any correcting action on the uremic status. Oral feeding with the diet containing casein (9.5% of energy value) was more effective as regards the reduction of uremia and maintenance of the general status of the body.
