title: The anorectic effect of satietin is unrelated to carbohydrate metabolism.
abstract: The effect of satietin and amphetamine on the carbohydrate metabolism of free fed and food deprived rats was studied. Rats deprived of food for 96 hours maintained normal glucose and glucagon blood levels but the blood concentration of insulin dropped from 232.02 +/- 23.93 to 12.48 +/- 0.71 pmol/l. Amphetamine (500 micrograms/animal, intracerebroventricularly) left in normally fed rats the blood concentration of glucose, insulin and glucagon unchanged. The same treatment, however, increased the insulin concentration in the blood of food deprived rats from 11.37 +/- 4.43 to 73.47 +/- 8.29 pmol/l. Glucose and glucagon, as well as insulin levels remained unchanged in both normally fed and food deprived rats when treated with satietin (20 micrograms/rat, intracerebroventricularly). It was concluded that the anorectic effect of satietin is unrelated to carbohydrate metabolism.
