Central Serotonergic Modulation of Carrageenin-induced Pedal Inflammation in Rats.

Pharmaceutical research

Bhattacharya SK, Das N.
PMID: 24271133
Pharm Res. 1985 Nov;2(6):315-8. doi: 10.1023/A:1016358004907.

Putative central serotonergic modulation of acute peripheral inflammation was investigated in rats, using the carrageenin-induced pedal edema as the experimental model. Serotonin and the serotonin precursor 5-hydroxytryptophan (5HTP) produced a dose-related inhibition of the peripheral edema when given intracerebroventricularly...

The involvement of monoamine neurotransmitter uptake in the discriminative stimulus effects of cocaine was examined in rats (n = 48) trained to discriminate 10mg/kg of this substance from saline in a two-level, water-reinforced (FR 20), drug discrimination situation. Compounds...

Assessment of the discriminative stimulus effects of the optical isomers of ecstasy (3,4-methylenedioxymethamphetamine; MDMA).

The discriminative stimulus effects of the stereoisomers of 3,4-methylenedioxymethamphetamine (MDMA) were studied in rats trained to discriminate 1.25mg/kg of (+)-MDMA or 3.5mg/kg of (-)-MDMA from saline, in a two lever, water-reinforced, drug discrimination situation. The isomers of MDMA and...

The effect of metergoline on endocrine responses to L-tryptophan.

Journal of psychopharmacology (Oxford, England)

McCance SL, Cowen PJ, Waller H, Grahame-Smith DG.
PMID: 22158889
J Psychopharmacol. 1987 Jan;1(2):90-4. doi: 10.1177/026988118700100205.

The effects of the 5-HT receptor antagonist, metergoline, on the prolactin and growth hormone responses to intravenous L-tryptophan were assessed in seven normal subjects. Pretreatment with metergoline lowered baseline prolactin concentration and abol ished the increase in prolactin following...

The unique effect of methiothepin on the terminal serotonin autoreceptor in the rat hypothalamus could be an example of inverse agonism.

Journal of psychopharmacology (Oxford, England)

Moret C, Briley M.
PMID: 22290996
J Psychopharmacol. 1993 Jan;7(4):331-7. doi: 10.1177/026988119300700404.

Slices of rat hypothalamus were pre-incubated with [(3)H] 5-hydroxytryptamine ([(3)H ] 5-HT), then superfused continuously and twice stimulated electrically. The effects of methiothepin, metergoline and alprenolol, all considered to be terminal 5-HT autoreceptor antagonists (although they also act at...

Stimulation of central 5-HT1D receptors causes hypothermia in the guinea-pig.

Journal of psychopharmacology (Oxford, England)

Skingle M, Higgins GA, Feniuk W.
PMID: 22298475
J Psychopharmacol. 1994 Jan;8(1):14-21. doi: 10.1177/026988119400800103.

The 5-HT(1) receptor agonist GR46611 (3-30 mg/kg s.c.) caused a dose-related decrease in rectal temperature in the adult guinea-pig. A lower dose (20 μg) administered directly into the lateral cerebral ventricle also caused a hypothermic response, suggesting that this...

Are 5-HT receptors involved in the sprouting of serotoninergic terminals following neonatal 5,7-dihydroxytryptamine treatment in the rat?.

Neurochemistry international

Hamon M, Nelson DL, Mallat M, Bourgoin S.
PMID: 20487810
Neurochem Int. 1981 Mar;3(1):69-79. doi: 10.1016/0197-0186(81)90051-6.

The neonatal administration of 5,7-dihydroxytryptamine to rats (100 mg kg(?1) s.c. on the 1st and 2nd day after birth) resulted in marked reductions in serotoninergic presynaptic markers ([(3)H]-5-HT synaptosomal uptake, tryptophan hydroxylase activity and endogenous 5-HT content) in various...

Increased slow wave sleep with 5-HT2 receptor antagonists: detection by ambulatory EEG recording and automatic sleep stage analysis.

Journal of psychopharmacology (Oxford, England)

Solomon RA, Sharpley AL, Cowen PJ.
PMID: 22282895
J Psychopharmacol. 1989 Jan;3(3):125-9. doi: 10.1177/026988118900300301.

The effect on slow wave sleep (SWS) of 5-HT antagonists with different affinities for 5-HT(1) and 5-HT(2) receptors was investigated using ambulatory EEG monitoring in normal volunteers. The selective 5-HT( 2) antagonists, ritanserin and cypropheptadine, increased SWS while the...

Alterations in dopamine and 5-hydroxytryptamine (5-HT) function during barbiturate dependence and withdrawal in mice.

Journal of psychopharmacology (Oxford, England)

Gray PL, Dawbarn D, Taberner PV.
PMID: 22158891
J Psychopharmacol. 1987 Jan;1(2):101-8. doi: 10.1177/026988118700100207.

Mice were rendered barbiturate-dependent by chronic feeding with barbital-con taining food. Brain dopamine turnover was significantly increased in barbital withdrawal, whereas 5-hydroxytryptamine (5-HT) turnover was significantly decreased. Severity of with drawal was assessed by measuring the convulsions following a...
