| Abstract: | Experiments lasting 15 days were made on rats fed intravenous isocaloric mixtures of the same composition (amino acids, glucose, fatty emulsion, mineral substances and vitamins), with one of the mixtures containing no fatty emulsion. It was noticed that intravenous feeding resulted in certain changes in body function, being consequent on the process of adaptation. The mixtures with and without fatty emulsion produced the same weight gain. However they brought about dissimilar shifts in other characteristics of the body status. The choice of adequate criteria is of importance for the assessment of the action of the different mixtures. |
