• Definitions:
• Substance released from mast cells during an allergic reaction. It causes itching, sneezing, increased mucous production, and nasal congestion. ...
• a compound found in mammalian tissues that causes stretching of capillaries, contraction of smooth muscle, and stimulation of gastric acid secretions; released during allergic reactions.
• A physiologically active depressor amine found in plant and animal tissue, derived from histidine by decarboxylation and released from cells in the immune system as part of an allergic reaction. It is a powerful stimulant of gastric secretion, constrictor of bronchial smooth muscle, and vasodilator.
• A chemical released by basophils and mast cells that causes nearby tissues to become swollen and inflamed.
• a naturally occurring substance that is released by the immune system after being exposed to an allergen. When you inhale an allergen, mast cells located in the nose and lungs release histamine. Histamine then attaches to receptors on nearby blood vessels, causing them to enlarge (dilate). ...
• A normal substance present in the body, which is released if tissues are injured. Histamine has been implicated as one of the substances in the blood considered to be a caus- ative factor in cluster headache, and it has also been considered a provocative factor in migraine headaches. ...
• A chemical made naturally in the body that is involved in inflammation, particularly inflammation related to an allergic reaction. Antihistamines, as the name suggests, are medicines that block the effect of histamine. (Histamine made in a laboratory is sometimes also used in challenge testing.)
• Chemical released by immune cells during an allergic reaction, causes swelling and inflammation
• A chemical released via the body's immune system in response to allergens.
• is the allergy chemical that is released from mast cell "allergy bombs" during an allergic reaction. Histamine causes itching, sneezing, swelling and a flood of mucus in the nose, itching, burning and swelling in the skin, headaches and plugging up of the sinuses, spasms and wheezing in the ...
• A chemical made in the body that is involved in inflammation (swelling, heat, pain and redness associated with damage to the tissues of the body), particularly during allergic reactions. ...
• a chemical present mainly in mast cells that, when released, causes many of the symptoms of allergy;
• (his´tua-m=en) A compound secreted by tissue mast cells and other connective tissue cells that stimulates vasodilation and increases capillary permeability. It is responsible for many of the symptoms of inflammation and allergy.
• A kind of cytokine that causes an inflammatory response to an injury, resulting in redness, swelling, warmth, and pain.
• A substance produced by the body, particularly during an allergic reaction. Histamine appears to be mainly responsible for manifestations of allergic rhinoconjunctivitis (hay fever) and contribute to the manifestations of asthma. ...
• Substance released by mast cells; important in the inflammatory response. Triggers vascular changes, including dilation of the blood vessels. A chemical released during an allergic reaction.
• The defense substance responsible for most inflammation. It is synthesized from the amino acid histidine and is secreted by mast cells, basophils, and blood platelets. ...
• A mediator of inflammatory reactions in the body, which may be part of an allergic reaction. Present in preformed granules in mast cells and basophils.
• a white crystalline compound involved in immune responses (hormone or chemical transmitter). It regulates production of stomach acid and is the main cause of allergic reactions. [C5H9N3] histo-
• a mediator released by mast cells
• Histamine is a substance your body injects into your bloodstream to help you stay alert. However, it is often triggered by allergens. It causes fluid to be released into the skin (which causes swelling and hives), and when released into the sinuses can cause a runny nose and watery eyes.
• An enzyme released by the body tissues in response to an allergy.
• An endogenous chemical involved in inflammation, allergic reactions, equilibrium and gastric acid secretion
• A natural chemical in the body, which causes an allergic reaction. For example, when a mosquito bites, its saliva instigates a release of histamine, which causes an annoying itch.
• found in mast cells, a type of white blood cell. Histamine has several functions including 1. Dilating capillaries, increasing capillary permeability causing a drop in blood pressure. 2. Contraction of smooth muscle of the lung. 3. Increase gastric secretion and 4. Accelerates heart rate.
• amine formed from histidine that stimulates gastric secretions and dilates blood vessels; released by the human immune system during allergic reactions
• Histamine is a biogenic amine chemical involved in local immune responses as well as regulating physiological function in the gut and acting as a neurotransmitter (Marieb, 2001, p.414). New evidence also indicates that histamine plays a role in chemotaxis of white blood cells.
