title: [Noradrenaline-H3 uptake by isolated rat organs with active and blockaded adrenoreceptors].
abstract: The beta-adrenoreceptor blocking agent propranolol was shown to activate noradrenaline-N3 absorption by the rat isolated organs by 30-180%. The alpha-adrenoreceptor blocking agent phentolamine only activated by 30-55% the noradrenaline-N3 absorption in the organs possessing the postsynaptic alpha-adrenoreceptors (ductus semen, spleen and amsll intestine). The beta-adrenoreceptor activator isopropylnoradrenaline decreased the intensity of noradrenaline-N3 absorption in all the organs by 15-50%. The alpha-adrenoreceptor activating agents (urine and mesaton) only depressed the noradrenaline-N3 absorption by 20-45% in the organs possessing postsynaptic alpha-adrenoreceptors. The data obtained suggest existence of reverse transsynaptic regulatory effects via adrenoreceptors of the cell-effector on the processes of noradrenaline absorption by adrenergic neuron.
