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...

Evidence of the existence of two different intraneuronal pools from which pharmacological agents can release serotonin.

Neurochem Int. 1981;3(5):289-94. doi: 10.1016/0197-0186(81)90015-2.

The effect of various drugs on the release of [(3)H]-serotonin from synaptosomes of reserpine-treated rats was compared with that obtained with synaptosomes of untreated animals. The increase in [(3)H]-serotonin release induced by d-fenfluramine was virtually abolished by reserpine; the...

In vivo [(3)H]ketanserin binding: effect of modifying synaptic serotonin levels.

Neurochem Int. 1988;12(1):85-9. doi: 10.1016/0197-0186(88)90152-0.

Most antidepressant therapies aim to increase the synaptic concentration of one or more of the monoamines. Synaptic monoamine levels are, however, extremely difficult to measure. In order to estimate synaptic levels of serotonin, an indirect method has been used....

Fluoxetine, a selective serotonin reuptake inhibitor used clinically, improves bladder function in a mouse model of moderate spinal cord injury.

After spinal cord injury, the upward conduction of the spinal cord is lost, resulting in the loss of micturition control, which manifests as detrusor sphincter dyssynergia and insufficient micturition. Studies have shown that serotonergic axons play important roles in...

Rapid changes in functional responsiveness of the 5-HT system after single-dose and multiple-dose treatment with antidepressants: effects of maprotiline and oxaprotiline and its enantiomers.

Journal of psychopharmacology (Oxford, England)

J Psychopharmacol. 1989 Jan;3(1):7-13. doi: 10.1177/026988118900300102.

Functional responsiveness to 5-HTP (L-5-hydroxytryptophan) and quipazine 24 h after one single dose and 24 h and 72 h after repeated administration (2.5 and 10 mg/kg twice daily for 7 days) of maprotiline, oxaprotiline and its (+) and (-)...

Regulation of Basal and nursing-induced secretion of growth hormone in the neonatal rat: the involvement of serotonergic, muscarinic cholinergic, alpha-adrenergic, somatostatin and growth hormone-releasing hormone systems.

Journal of neuroendocrinology

Kacsóh B, Grosvenor CE.
PMID: 19215503
J Neuroendocrinol. 1991 Oct 01;3(5):529-37. doi: 10.1111/j.1365-2826.1991.tb00314.x.

Abstract Various neural factors are involved in the suckling-induced increase in serum growth hormone (GH) levels in neonatal rats, and, in the present study the serotonergic, cholinergic, somatostatin and GH-releasing hormone (GHRH) systems were investigated. The serotonin (5-HT) precursor...

Expression level of long non-coding RNA colon adenocarcinoma hypermethylated serves as a novel prognostic biomarker in patients with thyroid carcinoma.

Bioscience reports

PMID: 33792624
Biosci Rep. 2021 Apr 30;41(4). doi: 10.1042/BSR20210284.

The present study attempts to identify the prognostic value and potential mechanism of action of colorectal adenocarcinoma hypermethylated (CAHM) in thyroid carcinoma (THCA) by using the RNA sequencing (RNA-seq) dataset from The Cancer Genome Atlas (TCGA). The functional mechanism...

Acute intrathecal administration of quipazine elicits air-stepping behavior.

Serotonin plays a pivotal role in the initiation and modulation of locomotor behavior in the intact animal, as well as following spinal cord injury. Quipazine, a serotonin 2 receptor agonist, has been used successfully to initiate and restore motor...

Chlorimipramine, fenfluramine and quipazine decrease 5-hydroxytryptamine synthesis in discrete rat brain nuclei.

Neurochem Int. 1986;8(3):403-12. doi: 10.1016/0197-0186(86)90014-8.

A procedure for studying 5-hydroxytryptamine synthesis by determining the rate of accumulation of 5-hydroxytryptophan after administering m-hydroxybenzylhydrazine, an inhibitor of aromatic-l-amino acid decarboxylase, and large doses of l-tryptophan was characterized. The utility of this method as an index of...

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.

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...
