Histamine Metabolism During Asthma Induced By Inhalation Challenge
In order to ascertain a role of histamine (HM) in the mediation of induced asthma, HM and Diamine Oxidase activity (DAO) were determined serially in plasma together with the Forced Expiratory Volume in the first second (FEV(,1)) in 18 subjects inhaling methacholine(MCH) by increments to permissible …

Regulation of dorsal raphe serotonergic neurons by histamine
… 5-HT2 receptors, orexin receptors and histamine receptors. In vitro, patch-clamp studies were performed in order to extend the investigation of 5-HT2, orexin and histamine receptors further in the hope of understanding the cellular mechanisms responsible for their actions. Most …

Regulation of STAT6 and STAT4 Phosphorlation by Histamine
… step in the modulation of T lymphocytes balance. Histamine alters the Thl/Th2 cytokine balance towards the Th2 cytokine profile and consequently plays a significant role in allergic diseases and asthma. This study was designed to investigate the effects of histamine on the phosphorylation of STAT6 …

Regulation of ERK1/2 and SAPK/JNK Phosphorylation by Histamine
… differentiation, and cell survival/apoptosis. Histamine is implicated in allergic disease and asthma and SAPK/JNK and ERK1/2 are involved in certain aspects of allergic inflammation such as TH2 differentiation and proliferation and apoptosis. This study was designed to investigate the effects …

Mast Cell Histamine Release Induced by Portuguese Man-of-War (Physalia) Venom
… and Uvnäs also studied the direct pruritic and histamine releasing effects of cnidarian (e.g. Physalia, Actinia, Cyanea), toxic extracts. While the anaphylactic effect, discovered by Richet and Portier, has been extended by numerous studies to provide the foundation of our current knowledge of …

Histamine H3 Receptor Heterogeneity in the Central Nervous System in Aging and Dementia.
Abstract The histamine H3R is a classic G-protein coupled receptor and is a potential therapeutic target for a number of central nervous system pathologies. Major pharmacological heterogeneity between and within species has hindered the clinical development of H3R-targeted drugs. The …

The effects of histamine on the gallbladder and exocrine pancreas of the guinea-pig
In the mammalian gastrointestinal tract histamine has multiple functions including contraction of smooth muscle and secretion of gastric acid. This study investigated the secretory and contractile actions of histamine on the exocrine pancreas and gallbladder of the guinea-pig respectively. …

Genetic effect of histamine N-methyltransferase (HNMT) polymorphism on chronic urticaria with aspirin hypersensitivity
… understood, but it has been known that released histamine by cutaneous mast cell activation is considered to be an important role. Biogenic histamine levels are regulated by histamine synthesis enzyme, L-histidine decarboxylase (HDC), and two metabolizing enzymes, histamine N-methyltransferase …

Head Trauma Release of Histamine from Dural Mast Cells Alters Blood-Brain Barrier: Attenuation with Zolantidine
… identify the role of dural mast cell (MC) histamine in trauma-induced increased permeability in the blood-brain barrier (BBB). A single line was scored partially through the left dorsal parietal skull. Immediately following the trauma, degranulation was seen in 39% of the MCs on the left …

Investigations into the roles of Histamine Receptor H1 and extracellular vesicles in ovarian cancer cell behaviour
… factors that can promote cancer metastasis is histamine, a compound involved in a plethora of physiological and pathological processes, including cancer. Indeed, activation of histamine receptor H1 (HRH1) by histamine stimulates growth of OC cells in vitro and promotes the release of …

Biogenic Amine Analysis of Fresh and Stored Bluefish (Pomatomus Saltatrix) and Microbiological Survey of Histamine-Forming Bacte
Changes in histamine, putrescine, and cadaverine concentrations in fresh and stored bluefish (Pomatomus saltatrix) were determined using a new HPLC method. The HPLC method utilized a 5.0% (w/v) trichloroacetic acid (TCA) extraction, pre-column fluorescamine derivitization, and fluorescence …
