Frontiers 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.

Perioperative uses of histamine antagonists [PDF]
, 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 ...

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

Are hypotension and rash after atracurium really caused by histamine release? [PDF]
, 1994 A prospective, randomized, double-blind study was performed in 40 patients (ASA class I-III) treated with atracurium to ascertain whether histamine release caused hemodynamic or cutaneous changes.

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

An improved method for the determination of histamine release in man: its application in studies with propanidid and thiopentone [PDF]
, 1972 Histamine release by propanidid and thiopentone was demonstrated with the use of a highly sensitive and specific method for determining histamine in human plasma. 5 min after i.v.

Function and Role of Histamine H1 Receptor in the Mammalian Heart
Pharmaceuticals, 2023 Histamine can change the force of cardiac contraction and alter the beating rate in mammals, including humans. However, striking species and regional differences have been observed. Depending on the species and the cardiac region (atrium versus ventricle)

Role of Histamine in Modulating the Immune Response and Inflammation
Mediators of Inflammation, 2018 Inflammatory mediators, including cytokines, histamine, bradykinin, prostaglandins, and leukotrienes, impact the immune system, usually as proinflammatory factors.
