    Abstract:
    DL-alpha-methyl-p-tyrosine methyl ester hydrochloride affected the hyperphagia and hypothermia characteristic of the genetically obese mouse (genotype, ob/ob) throughout an experimental period of 5 days. Intraperitoneal injections of 100 mg/kg body weight, daily, resulted in a significant increase in the average daily food consumption by 60 per cent, already elevated 35 per cent above that of lean litter-mates. The drug, administered at the same dose, caused a similar percentage elevation of food intake in the lean litter-mates. Rectal temperatures of obese mice were raised significantly throughout the 5-day period by an average of 0.95 degrees C, following administration of the drug. There was a significant rise of 0.75 degrees C in the rectal temperature of lean mice on 2 of the 5 days in the period. Body weight remained unchanged. Further experiments are necessary to determine the site of action at which DL-alpha-methyl-p-tyrosine brings about these effects at this dose in lean and obese mice.
