title: [Effect of the tetracyclic antidepressants pyrazidol and inkazan on the adrenergic nerve transmission in the rat vas deferens].
abstract: The effect of new tetracyclic antidepressants pyrazidol and inkazan on adrenergic neurotransmission in the isolated rat vas deferens was studied by examining vas deferens contractions in response to the transmural electric stimulation of the postganglionic sympathetic nerves and addition of noradrenaline (NA) or BaCl2. Pyrazidol and inkazan were found to be capable to increase vas deferens contractions in response to transmural electric stimulation or addition of NA. When given in high concentrations, these antidepressants inhibit the adrenergic neurotransmission since inkazan possesses low sympatholytic activity and pyrazidol exhibits certain alpha-adrenolytic effect.
