The Effects of Histaminergic Agents in the Nucleus ccumbens of Rats in the Elevated Plus-Maze Test of Anxiety [PDF]

Iranian Journal of Psychiatry, 2010
"n Objective: "n The nucleus accumbens (NAc) receive histaminergic neurons from tuberomammillary nuclei. There are reports indicating that central histamine systems are involved in many physiological behavioral processes, including anxiety.

Novel therapeutic targets for chronic visceral pain in gastrointestinal disorders

British Journal of Pharmacology, EarlyView.
Chronic visceral pain imposes a major clinical challenge in gastroenterology and beyond, profoundly impacting patients' quality of life. However, limited understanding of its complex, multifaceted pathophysiology, encompassing both peripheral and central mechanisms, continues to impede the development of effective management strategies.

Polarized effects of adenosine on blood–brain barrier integrity: Tightening from the luminal and opening from the abluminal side

British Journal of Pharmacology, EarlyView.
Background and Purpose Adenosine as a signalling molecule modifies blood–brain barrier (BBB) tightness in pathological conditions. Our aim was to investigate the direct and polarized effects of adenosine on the BBB using co‐culture and in vivo models. Experimental Approach The expression of adenosine receptors was measured by qRT‐PCR.

Bronchial biopsy and sequential bronchoalveolar lavage in atopic cough: In view of the effect of histamine H1-receptor antagonists

Allergology International, 2000
We have shown that some patients presenting with chronic bronchodilator-resistant non-productive cough have global atopic tendency, airway cough hyper-sensitivity without non-specific bronchial hyperresponsiveness and eosinophilic inflammation of the ...

Drugs that act on both G protein‐coupled receptors (GPCRs) and kinases: potentiation of effects, side effects and general aspects of drug pleiotropy

British Journal of Pharmacology, EarlyView.
Abstract Background A drug designed for a specific target often interacts with multiple targets, either unintentionally or as part of its intended mechanism of action. This has been called pharmacological pleiotropy or polypharmacology. There are key endogenous ligands such as ATP, GABA and glutamate that act on various proteins in humans. Furthermore,

Histamine analogues, XXXV: 2-substituted histamine derivatives containing classical moieties of H2-antagonists--a novel class of H1-agonists

, 1993
A new type of H1-agonists resulted from the combination of the essential histamine structure with parts of H2-antagonists. 2,4-Disubstituted imidazole derivatives were synthesized by reaction of imidic acid methyl esters with 1,3-dihydroxypropanone, 1,4 ...

Rebound Pruritus and Urticaria After Discontinuation of Chronic Antihistamine Use—A Scoping Review

Clinical &Experimental Allergy, EarlyView.
Rebound pruritus and urticaria have been reported after discontinuation of chronic cetirizine or levocetirizine use only. Symptoms typically occur within 0.5–5 days after stopping therapy and appear more frequently reported in female patients. Re‐initiation of antihistamines is the most commonly effective management strategy, highlighting the need for ...
