| Abstract: | In experiments on 15 freely moving rabbits cholecystokinin octapeptide sulfate (CCK-8-S) in a dose of 10 ng considerably suppressed alimentary behaviour of the animals elicited by electrical stimulation of the lateral hypothalamus. Increasing of the peptide doses to 100 and 200 ng elicited an analogous effect. CCK-8-NS in 10 ng dose produced a lesser effect on feeding of the animal, but increasing of the dose of nonsulphated CCK to 100 ng led to a considerable prolongation of feeding. CCK-8-S and CCK-8-NS in doses used did not affect the reaction of avoidance in rabbits caused by electrical stimulation of the ventromedial nucleus of the hypothalamus. |
