5-Hydroxytryptamine (5-HT)2 receptor involvement in acute 5-HT-evoked scratching but not in allergic pruritus induced by dinitrofluorobenzene in rats.
We investigated the role of serotonin (5-hydroxytryptamine; 5-HT)2 and 5-HT3 receptor subtypes in acute itch-associated scratching behavior as well as in an allergic pruritus model in rats. Intradermal 5-HT evoked hind limb scratching directed toward the injection site in naïve rats. Scratching behavior was significantly reduced by pretreatment with the 5-HT2 receptor antagonist ketanserin. Int...
متن کاملDopamine and 5-HT receptor sensitivity does not correlate with neostriatal dopamine or 5-HT content.
To explore associations of neostriatal (NST) endogenous levels of dopamine (DA) and serotonin (5-HT) with sensitivity of their receptors, graded doses of 6-hydroxydopamine HBr (0 to 400 micrograms, ICV; 6-OHDA; desipramine pretreatment, 20 mg/kg IP) were given to rats between birth (P 0) and P 42. Numbers of vacuous chewing movements (VCMs) induced by SKF 38393 or m-chlorophenylpiperazine (m-CP...
متن کاملIndoline derivatives as 5-HT(2C) receptor agonists.
A series of 1-(1-indolinyl)-2-propylamines was synthesised and evaluated as 5-HT(2C) receptor agonists for the treatment of obesity. The general methods of synthesis of the precursor indoles are described. The functional efficacy and radioligand binding data for all of the compounds at 5-HT(2) receptor subtypes are reported. A number of compounds were found to reduce food intake in rats after o...
متن کاملRelationship between neonatal testosterone and 5-hydroxytryptamine (5 HT) in controlling the pattern of LH release in adult rats
Relationship between neonatal testosterone and 5-hydroxytryptamine (5-HT) in controlling the pattern of LH release in adult rats was investigated in this study. Hypothalamic 5-HT concentrations are transiently lower in male as compared to female Wistar rats in the second week post-partum (pp). It has also been shown that pharmacologically potentiating 5-HT activity during this period feminizes ...
