title: [Cyclic analogs of ACTH fragments in self-stimulation and grooming behavior in rabbits].
abstract: In present study new cyclic fragments of ACTH EHFRWGKPVG--NH2 and KHFRWG--NH2 were investigated in organization of self-stimulation and grooming behaviour in rabbits. Intracerebroventricular injections of EHFRWGPVG--NH2 in doses of 0.1-2.5 g evoked significant increases of self-stimulation and in doses of 4-5 g suppressed self-stimulation in rabbits. The effect of other fragments KHFRWG--NH2 on self-stimulation was not statistically significant. Both fragments induced excessive grooming behaviour in rabbits. The effects of these fragments persisted of 48-72 hours.
