Histamine: A Mediator of Intestinal Disorders—A Review

open access: yesMetabolites, 2022
Within the gastrointestinal tract, histamine is present at relatively high concentrations, especially during inflammatory processes. Histamine is a biogenic amine with numerous effects on many cell types, mediated by the activation of its four different ...

Histamine binding activity of surface-modified yeast by histamine binding protein (HBP)

open access: yesAMB Express, 2021
Histamine is an immune mediator that is mainly secreted when an immediate, rapid response is needed in the body, and an excessive secretion of histamine or lack of enzymes that degrade histamine can result in various side effects.

Histamine in the brain [PDF]

open access: yesFrontiers in Systems Neuroscience, 2014
Brain aminergic pathways are organized in parallel and interacting systems, which support a range of functions, from homoeostatic regulations to cognitive, and motivational processes. Despite overlapping functional influences, dopamine, serotonin, noradrenaline and histamine systems provide different contributions to these processes.

Progress in Allergy Signal Research on Mast Cells: Up-Regulation of Histamine Signal-Related Gene Expression in Allergy Model Rats

open access: yesJournal of Pharmacological Sciences, 2008
Brown Norway allergy model rats sensitized to toluene 2,4-diisocyanate (TDI) were developed. Histamine H1receptor mRNA level was elevated in nasal mucosa of allergy model rats after the provocation with TDI, which was followed by H1-receptor up ...

Granuloma pouch and skin histamine of the rat [PDF]

open access: yes, 1958
Using the granuloma pouch technique of SELYE, effect of modification in local histamine on the inflammatory tissue reactions was examined in rats. The increase in the weight of pouch wall and histological inflammatory changes were distinctly inhibited in

Perioperative uses of histamine antagonists [PDF]

open access: yes, 1990
Histamine release and adverse pseudoallergic/allergic reactions during the perioperative period occur frequently. The incidence of such reactions is 20%-30% for all grades of severity, 1%-5% for systemic reactions, and 0.1%-0.5% for life-threatening ...

Effects of histamine on human periodontal ligament fibroblasts under simulated orthodontic pressure.

open access: yesPLoS ONE, 2020
As type-I-allergies show an increasing prevalence in the general populace, orthodontic patients may also be affected by histamine release during treatment.

Perioperative nonspecific histamine release: a new classification by aetiological mechanisms and evaluation of their clinical relevance [PDF]

open access: yes, 1993
As a consequence of the performance of a randomized controlled clinical trial on perioperative histamine release and cardiovascular and respiratory disturbances, several types of increases in plasma histamine had to be distinguished instead of only two ...

Determination of histamine in human plasma: the European external quality control study 1988 [PDF]

open access: yes, 1990
There is an increasing interest in measuring human plasma histamine levels in various clinical conditions. A variety of 'old' and newly developed techniques are applied to meet this demand.

Histamine can be Formed and Degraded in the Human and Mouse Heart

open access: yesFrontiers in Pharmacology, 2021
Histamine is metabolized by several enzymes in vitro and in vivo. The relevance of this metabolism in the mammalian heart in vivo is unclear. However, histamine can exert positive inotropic effects (PIE) and positive chronotropic effects (PCE) in humans ...
