INFLUENCES OF DIFFERENT ADRENOCEPTOR AGONISTS AND ANTAGONISTS ON AMPHETAMINE- INDUCED CLIMBING IN MICE
Authors
Abstract:
Administration of apomorphine and amphetamine induces climbing behavior in mice due to stimulation of brain dopamine receptors. In the present study, the effects of adrenoceptor agonists and antagonists on amphetamine-induced climbing have been investigated. Intraperitoneal (i.p.) injection of different doses of amphetamine (2,4 and 8 mglkg) induced climbing in mice (p<O.OOO 1). The u2- adrenoceptor agonist clonidine decreased the climbing induced by amphetamine (p<0.01). The adrenoceptor antagonists prazosin, yohimbine and propranolol did not alter amphetamine response. It may be concluded that α1- and α2-adrenoceptor stimulation decreases amphetamine- induced climbing behavior indirectly through changing dopamine levels.

In the present study the effects of both CCK receptor agonists and antagonists on antinociception induced by morphine in the tail-flick test have been evaluated. M orphine induced dose-dependent antinociception in mice. The response of morphine was potentiated by sulfated cholecystokinin-8 (CCK-8S) but not by unsulfated cholecystokinin-8 (CCK-8U). The CCK receptor antagonists MK-329 and L-...

In this study, the influence of dopamine receptor agonists and antagonists on antinociception induced by bac10fen has been examined in the formalin test. The GABA-B agonist bac10fen induced antinociception in both phases of the formalin test in mice. The dopamine receptor agonists SKF 38393 and quinpirole also induced antinociception in both phases of the test. SKF 38393 but not quinpirole ...

The effects of caerulin, a CCK receptor agonist, and proglumide, a receptor antagonist, on hyperalgesia induced by sciatic nerve ligation, was studied in mice. Tolerance to the morphine response was obtained 3,7, 14,21 and 28 days after unilateral sciatic nerve ligation. Maximum hyperalgesia was found 14 days after nerve ligation. Caerulin increased morphine antinociception in nerve-ligated ani...
full textThe effects of Adrenergic agents on the dopaminergic-induced sniffing
There is evidence indicating that adrenoceptor mechanisms may influence some of the behaviors in rat. However the role of adrenoceptor agents on sniffing has not been identified. In the present study, the influence of adrenoceptor agents on sniffing induced by apomorphine and amphetamine has been investigated. Male Albino rats, weighing 150-250 g were used for all experiments. The behavior wa...
