Histamine Release by Anaphylatoxin
Nature, 1951EARLY studies of the mechanism of anaphylaxis led to two apparently contradictory views : the so-called ‘humoral theory’, according to which the blood is the site of production of a toxin, the anaphylatoxin1–4; and the ‘cellular theory’, which localizes the anaphylactic reaction in the cells, and assumes that this reaction causes the release of ...

Histamine Release by Contrast Media
Radiology, 1971The blood draining organs with a high histamine content was sampled and elevation of plasma histamine was found to result from injections of certain contrast media. All methylglucamine contrast media tested to date (acetrizoate, diatrizoate, and iodipamide) produced such elevations.

Proceedings, annual meeting, Electron Microscopy Society of America, 1973
Isolated rat peritoneal mast cells respond to compound 48/80 and to antigen with degranulation and histamine (Hi) release. In electronmicroscopic studies the initial structural changes were seen at the periphery of the cell immediately adjacent to the cell membrane, indicating that the effect of compound 48/80 (and of antigen) starts from the cell ...

Myocardial infarction and histamine release
Agents and Actions, 1986On the basis of previous data suggesting the involvement of cardiac histamine in ischemic heart disease (IHD), we evaluated plasma histamine (H) and creatine-kinase isoenzyme (CK-MB) level in cardiac and healthy subjects. 20 patients with acute myocardial infarction (AMI) (10 developing AMI in Hospital, thus making possible the detection of plasma H ...

(1) Histamine release in man could be demonstrated using the fluorometric histamine assay in plasma as a reliable test. (2) Histamine release in animals may be relevant in some cases for human subjects, as shown for anaesthetic drugs and plasma substitutes on gelatin basis.

Leucocyte Histamine Release in Migraine
Headache: The Journal of Head and Face Pain, 1980SYNOPSIS Although histamine has been suggested as a possible vasoactive mediator in the pathogenesis of migraine, the mechanism of histamine release and its exact role in the pathophysiology of migraine is unclear. The spontaneous release of histamine from plasma‐free leucocyte suspensions was examined in 9 patients with 5 types of ...

Histamine release by platelet aggregation
Agents and Actions, 1990Coincubation of rat serosal mast cells with human platelets leads to a significant release of histamine. which dose-dependently increases when platelet aggregation is induced by various concentrations of arachidonic acid. In turn, histamine enhances platelet aggregation induced by different agonists, this effect being mimicked by pyridyl-ethyl-amine ...

Histamine Release by Air Pollutants
Archives of Environmental Health: An International Journal, 1969The release of histamine in guinea pig lungs after inhalation of 1 to 50 ppM SO/sub 2/, 10 ppM NO/sub 2/, or cigarette smoke was minimal in terms of the amount released spontaneously. Histamine release was not significant until concentrations caused severe lung damage.

Histamine release by vagal stimulation
Agents and Actions, 1983The content of acetylcholine and histamine in the effluent of isolated, vagally innerved guinea-pig auricles was determined. Spontaneous or stimulation-induced overflow of acetylcholine was detected only in the presence of acetylcholinesterase inhibitors.

Isotope assay of histamine release
Biochemical Medicine, 1974Abstract The single isotopic enzymatic histamine assay system has been adopted for the studying of the release of histamine from sensitized human leukocytes when challenged with the appropriate allergen. It is a simple, rapid, sensitive, and reproducible method based on the use of the enzyme histamine N-methyltransferase and the high specific ...
