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.

IL-4 protein and mRNA have recently been detected in pure basophil cultures after stimulation. It has also been established in mixed leukocyte cultures obtained by elutriation and challenged with anti-IgE that the basophil is the only cell that makes ...

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 ...

Triggering of histamine release from rat mast cells by divalent antibodies against IgE-receptors.
Journal of Immunology, 1978Antibodies against receptor molecules for IgE on rat basophilic leukemic (RBL) cells were prepared by immunization of a rabbit with immune precipitates composed of IgE-receptor complexes and anti-IgE.

Release of Histamine by Ammonia
Nature, 1949HISTAMINE 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

The histamine-releasing capability of bacterial lipopolysaccharides (LPS) was examined in human leukocyte suspensions. LPS alone did not release histamine, but it was found to enhance the histamine release caused by bacteria in basophils from persons sensitized to these bacteria.

Human Recombinant Histamine-Releasing Factor
International Archives of Allergy and Immunology, 1997Histamine-releasing factors (HRF) have received much attention over the last 17 years. With the availability of molecular biology techniques, cloned molecules have been identified as HRF. Examples include various interleukins, chemokines and the IgE-dependent HRF This human recombinant HRF (HrHRF) is a novel cytokine with no homology to any known ...

Histamine release by gastric stimulants
Nature, 1975IT is a matter of debate whether histamine in the gastric mucosa acts as a local chemical mediator for other gastric stimulants1–5, and the isolated bullfrog mucosa provides a convenient model for investigation of the question. The preparation responds to gastric stimulants such as pentagastrin, acetylcholine and histamine; the secretory rate can be ...
