The Effect of 5HT3 Agonist Receptor of the Lateral Hippocampal on Amnesia Induce by Morphine in Mice
Background and Objective: It has been shown that the opioidergic system exerts widespread effects on cognitive functions. Interactions between opioid and serotonin receptors have been reported in some brain structures such as the dorsal hippocampus, thus a functional interaction between opioids and serotonin seems possible concerning memory control. The purpose of this study was to assess the e...
متن کاملThe effect of CCK receptor agonists and antagonists in sciatic nerve-ligated mice
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...
متن کاملEFFECTS OF DOPAMINE RECEPTOR AGONISTS AND ANTAGONISTS ON BACLOFEN-INDUCED ANTINOCICEPTION IN FORM ALIN TEST
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 ...
متن کاملEFFECTS OF CCK RECEPTOR AGONISTS AND ANTAGONISTS ON MORPHINE-INDUCED ANTINOCICEPTION IN MICE
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-...
متن کاملStudy of 5HT3 and HT4 receptor expression in HT29 cell line and human colon adenocarcinoma tissues.
BACKGROUND Serotonin (5HT) has been shown to be a mitogenic factor in several carcinomas. Its mitogenic effect is elicited through a wide range of 5HT receptor subtypes. In this study, the effects of 5HT, 5HT3 (1-phenylbiguanide hydrochloride) and 5HT4 (cisapride) agonists in promoting the growth of the HT29 cell line and the growth-inhibition effect of the 5HT3 receptor antagonist (Y-25130 hyd...
