Abstract
Intraperitoneal injections of 375 mg. of glucose and normal saline were given to hypothalamic hyperphagic rats and normal controls maintained on a 23 1/2-hr. deprivation schedule. Amount of food consumed in the 1/2 hr. beginning 15 min. after injection was determined. Under the 375-mg. glucose dosage food intake in the hyperphagic group was depressed 24.34% in comparison with the saline control level, while in the control group depression was 15.69%. With the 750-mg. dosage, depression in the hyperphagic group was 54.83%, and in the control group, 25.67%. Differences between groups were significant at both dosage levels. A possible explanation for the exaggerated anorexic effect of glucose in hyperphagic rats is suggested.
