title: Effect of insulin and 2-deoxy-d-glucose on the food intake of infant rats.
abstract: The effects of glucoprivation on the food intake have been determined in infant rats up to weaning. It was found that insulin reduced the milk intake of 9, 13 and 17-day-old males and females for three hours after treatment. In 24-day-old pups food intake increased for three hours after insulin administration, and decreased during the next 21-hour period. 2-deoxy-D-glucose increased the food intake in 28-day-old rat pups only. It was concluded that the inability of rat pups to correct glucoprivation by a subsequent increase of food intake is a consequence of the inadequate development of hypothalamic regulatory mechanisms. Glucoprivation stimuli are ineffective inducers of short-term hyperphagia of rat pups until the age of 24-28 days.
