Histamine Release by Anaphylatoxin

Nature, 1951
EARLY 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 platelet aggregation [PDF]

open access: possibleAgents and Actions, 1990
Coincubation 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 ...

Learned Histamine Release

Science, 1984
Most of the effort directed at understanding the problems of allergy has focused on the interacting components of the immune system. The possibility that histamine may be released as a learned response has now been tested. In a classical conditioning procedure in which an immunologic challenge was paired with the presentation of an odor, guinea pigs ...

Patterns of histamine release in the brain [PDF]

open access: possibleAgents and Actions, 1991
The pattern of histamine release has been investigated in various brain areas of anaesthetized cats and conscious, freely moving rats by the push-pull technique. In the hypothalamus, medial amygdaloid nucleus and mamillary body of the anaesthetized cat, histamine was found to be released according to an ultradian rhythm with a frequency of 1 cycle per ...

Release of Histamine by Ammonia

Nature, 1949
HISTAMINE is released from tissues in anaphylaxis, by trypsin, peptones, snake poisons, curare and diamidines. Garan1 has shown that ammonia vapour liberates histamine from guinea pigs' lungs. The following experiments show that histamine is quantitatively released from striated muscle in a solution of ammonium chloride, but that the effect is entirely

Histamine release by vagal stimulation

Agents and Actions, 1983
The 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.

The release of histamine by free radicals

Free Radical Biology and Medicine, 1988
An extensive discussion of the available evidence about the release of histamine by free radicals is presented. In addition, the involvement of the free-radical driven release of histamine in human pathophysiology is debated.

Histamine Release by Contrast Media

Radiology, 1971
The 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.

Myocardial infarction and histamine release

Agents and Actions, 1986
On 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 ...

Histamine Storage and Release

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 ...
