    Streszczenie angielskie: The aim of the present study was to examine the influence of 3-month administration of the typical neuroleptic haloperidol (1 mg/kg/day) and the atypical one clozapine (30 mg/kg/day) on the expression of the NMDA-R1 mRNA in different brain structures using in situ hybridization in rats. A long-term treatment with haloperidol decreased the NMDA-R1 mRNA level in intermediate and caudal parts of the caudate-putamen and in more caudally localized regions of parietal and frontal cortices, but increased it in the CA1 region of the hippocampus. No significant changes in the nucleus accumbens, insular cortex, CA3 and dentate gyrus of the hippocampus were found after haloperidol administration. Clozapine did not influence the NMDA-R1 mRNA expression in the hippocampus, as well as in the intermediate and caudal regions of the caudate-putamen, but significantly increased it in the rostral region of the latter structure, in the nucleus accumbens and insular cortex. The present study suggests that both these neuroleptics influence the expression of the mRNA of the NMDA-R1 subunit in brain structures which are thought to be important for development of psychotic symptoms.

    Streszczenie angielskie: Mirtazapine (MIR) is an antidepressant drug which enhances noradrenergic and serotonergic 5-HT1A neurotransmission via antagonistic action at central ŕ2-adrenergic autoreceptors and heteroreceptors. We reported earlier that tricyclic antidepressants administered repeatedly induced adaptive changes in the central dopaminergic D2/D3 receptors. Therefore, we designed our present study to determine whether repeated MIR treatment could evoke similar effect. The experiments were carried out on male Wistar rats. MIR was administered at a dose of 10 mg/kg once or repeatedly (twice daily for 14 days). The obtained results showed that MIR administered repeatedly potentiated the hyperlocomotion induced by D-amphetamine but not by quinpirole or 7-OH-DPAT. Biochemical study showed that MIR administered repeatedly decreased the binding of [3H]quinpirole (a D2/D3 receptor agonist) in the shell part of the nucleus accumbens septi and in the islands of Calleja but did not change the binding in the nucleus caudatus (medial or lateral). On the other hand, both acute and repeated drug treatment did not change the [3H]7-OH-DPAT (a D3 receptor agonist) binding sites in the islands of Calleja as well as in the shell part of nucleus accumbens septi. In addition, MIR did not alter the level of mRNA encoding dopamine D2 receptors, not only after repeated but also after acute treatment. The above results indicate that repeated MIR administration did not induce any adaptive change (behavioral and biochemical changes) in the dopaminergic D2/D3 system.

    Streszczenie angielskie: Mirtazapine (MIR) is an antidepressant which enhances noradrenergic and serotonergic 5-HT1A neurotransmission via antagonism of central ŕ2-adrenergic autoreceptors and heteroreceptors. The drugs does not inhibit noradrenaline and serotonin reuptake but blocks the 5-HT2 and 5-HT3 receptors and has high affinity only for central and peripheral histamine H1 receptors. The present study was was aimed at determining whether repeated MIR treatment induced adaptive changes in the ŕ1-adrenergic receptors, similar to those reported by us early for tricyclic antidepressants. The experiments were carried out on male mice and rats. MIR was administered at a dose of 10 mg/kg oce or repeatedly (twice daily for 14 days). The obtained results showed that MIR administrated repeatedly potentiated the methoxamine- induced exploratory hyperactivity in rats and clonidine-induced aggressiveness in mice, those effects being mediated by ŕ1-adrenergic receptors. MIR given repeatedly (but not acutely) increased the binding (Bmax) of [3H]prozosin to ŕ1-adrenergic receptors in cerebral cortex, however, the ability of the ŕ1-sdrenoreceptor agonist phenylephrine to compete for the these sites was not significantly changed. The above results indicate that repeated MIR administration increases the responsiveness of ŕ1-adrenergic system (behavioural and biochemical changes), as tricyclic do. However, the question whether the increased functional responsiveness found in the present study is important for the clinical antidepressant efficacy, remains open.

    Streszczenie angielskie: The purpose of the present study was to evaluate the effects of acute and repeated treatment with two antidepressant drugs (ADs) of opposite pharmacological profile, i.e. tianpetine (TIA, serotonin reuptake enhancer) and fluoxetine (FLU, serotonin reuptake inhibitor) on the levels of Met-Enkephalin, (Met-Enk, a member of opioid peptidefamily, which has been suggested to play a role in the mechanism of action ADs) as well as on mRNA coding for proenkephalin (mRNA PENK) in various regions of the rat brain, pituitary, drenal glands and plasma. male Wistar rats treated acutely or repeatedly (10 mg/kg p.o., twice daily for 14 days) with TIA or FLU. Tissue for biochemical experiments was taken 2 h after last dose of appropriate drug. The levels of Met-Enk were estimated by radioimmunoassay, mRNA PENK was measured using in situ hybridization. From the results obtained in the present study it may be concluded thart repeated adminiostration of TIA or FLU induced similar changes in the levels of Met-Enk in the rat hippocampus, striatum, hypothalamus and neurointermediate lobe of pituitary. Such an effect is interesting, especially if one takes into account the differences in pharmacological profile between these two antidepressant drugs. It may be suggested that serotonin level might not be crucial for inducing the alterations in the content of Met-Enk. Since we did not observe any changes in the levels of PENK mRNA in the studied rat brain regions after repeated administration of TIA or FLU, it seems that the observed changes in the levels of Met-Enk...

    Streszczenie angielskie: Reboxetine (REB) is a member of a new class of antidepressants drugs, which selectively inhibit the neuronal reuptake of noradrenaline. It is devoid of any affinity for neurotransmitter receptors nor does it inhibit monoamine oxidases A or B. Since our earlier studies have shown that antidepressant drugs administered repeatedly increase the responsiveness of ŕ1-adrenergic receptors and induce the up-regulation of postsynaptic dopamine D2/D3 receptors in the rat brain, we designed the present experiments to determine whether repeated administration of REB evokes similar effects. The experiments were carried out on male Wistar rats. REB was administered at a dose of 10 mg/kg (or 30 mg/kg in some cases) once or repeatedly (twice daily for 14 days). The obtained results show that REB administered repeatedly increased exploratory behavior induced by phenylephrine and potentiated the hyperlocomotion induced by D-amphetamine. These behavioral effects indicate the hyperresponsiveness of 1-adrenergic receptors. Biochemical studies did not show any changes in the binding parameters of [3H]prazosin (Bmax or Kd), but the ability of the ŕ1-adrenergic receptor agonist, phenylephrine, to complete for these sites was significantly increased upon repeated administration of REB. Locomotor activity induced by quinpirole was not changed, although there was a potentiation of 7-OH-DPAT-induced locomotor hypereactivity in rats receiving repeated administration of REB. At the same time no significant changes in the binding of [3H]quinpirole and [3H]7-OH-DPAT, or at the level of mRNA...

    Streszczenie angielskie: Treatment of the patients suffering from therapy-resistant unipolar depression with joint administration of imipramine (twice daily, 100-150 mg/day) an amantadine (twice daily, 150 mg/day) for four to six weeks resulted in the significant increase in the binding of [3H]17-OH-DPAT to dopamine D3 receptors in the peripheral blood lymphocytes. This effect correlated well with the clinical improvement, estimated with Hamilton's Depression Rating Scale. In the light of the above data, it seems justified to postulate that joint therapy with imipramine and amantadine may be successful in the treatment-resistant unipolar depression.
