[Effects of glucose, aminoacid or lipid infusion on dietary self-selection in the rat].
Rats with an intracardiac chronic catheter were offered dietary self-selection between glucids, proteins and lipids intakes. They are infused continuously with 0.9% NaCl except on the test day with glucose, amino acids or lipids. Parenteral load is about 25% of the daily total food intake. With glucose infusion a selective decrease in glucids intake is observed of about 80% of the caloric glucose  load. Aminoacidemic and lipidic infusions lead not only to decrease respectively in proteins and lipids intakes, but also in glucids intakes. So, in this case, total caloric intake decreased more than caloric load. Results are discussed in the hypothesis of existence of a hepatic chemosensibility.
