[Effect of carbidine on dopamine turnover in the rat corpus striatum].
It has been shown that carbidine increases the level of homovanillic acid (HVA) in the corpus striatum of the rat brain. The changes in HVA level allowed forming a judgement on dopamine turnover. By the intensity of this effect, carbidine proved inferior to typical neuroleptics--triphtazine and ftorfenazin. The antidepressant ftoracizin did not alter HVA level. Carbidine ranks between neuroleptics and antidepressants in terms of the effect on dopamine turnover.

[Effect of the tetracyclic antidepressants pyrazidol and inkazan on the adrenergic nerve transmission in the rat vas deferens].
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.

[Neuromediator content in the synaptic vesicles of rat adrenergic nerves in some pharmacological actions].
Cytochemical electron microscopy was employed to study the content of neurotransmitters in the synaptic vesicles of adrenergic nerve fibers of Vas deferens of the rat following depletion of the meadiator's reserves by tyramine and subsequent accumulation of exogenous norepinephrine. Subject to investigation was also the effect of antidepressants (phthoracizine and imipramine) on the accumulation of exogenous norepinephrine in the synaptic vesicles. Phthoracizine and imipramine (1 and 10 gamma/ml) are shown to block the acculation of norepinephrine in the vesicles, when the mediator is introduced in a concentration of 0,5 gamma/ml, and not to impede this process, if the mediator's concentration is increased to 30 gamma/ml.

[Effect of certain GABA-ergic substances on dopamine metabolism in the rat brain].
Effect of the GABA-ergic drugs, sodium hydroxybutyrate, n-dipropylacetate (n-DPA) and piracetam, has been studied on the level of homovanillic acid (HVA) and activity of GABA-transaminase in the striate body of the rat brain. It has been established that piracetam in doses of 500 and 400 mg/kg, n-DPA in a dose of 200 mg/kg and sodium hydroxybutyrate in a dose of 500 mg/kg do not affect the HVA level or activity of GABA-transaminase. The data obtained are likely to support a suggestion about a possible relationship between the GABA-ergic and dopaminergic mediator system.

[Influence of carbidine on the noradrenaline level in the adrenergic nerve fibers in the peripheral tissues].
By employing fluorescent histochemistry and spectrofluorimetry the influence of an original psychotropic substance -- carbidine on the level, localization and accumulation of the adrenergic mediator in Vas deferens, dura mater and the kidney capsule was studied "in vivo" and "in vitro". Carbidine was shown to capable of liberating the adrenergic mediator from the sympathetic nerve fibres of the peripheral tissues without affecting the capture and accumulation of exogenous norepinephrine by adrenergic nerve fibres.
