| allergic extract | Extract (usually containing protein) from various sources, e.g., food, bacteria, pollen, and the like, suspected of specific action in stimulating manifestations of allergy; may be used for skin testing or desensitization. Synonym: allergic extract. (05 Mar 2000) |
|---|---|
| allergic granulomatosis | <syndrome> Widespread necrotizing angiitis with granulomas. Pulmonary involvement is frequent. Asthma or other respiratory infection may precede evidence of vasculitis. Eosinophilia and lung involvement differentiate this disease from polyarteritis nodosa. (12 Dec 1998) |
| allergic granulomatous angiitis | <syndrome> Widespread necrotizing angiitis with granulomas. Pulmonary involvement is frequent. Asthma or other respiratory infection may precede evidence of vasculitis. Eosinophilia and lung involvement differentiate this disease from polyarteritis nodosa. (12 Dec 1998) |
| allergic inflammation | <immunology> The bodys response to an allergic stimulus. This can be localised to one area or generalised and may include: rash, itching, hives, swelling, difficulty breathing, and/or low blood pressure. (27 Sep 1997) |
| allergic purpura | Nonthrombocytopenic purpura due to sensitization to foods, drugs, and insect bites. Synonym: anaphylactoid purpura. (05 Mar 2000) |
| allergic reaction | <immunology> The bodys response to an allergic stimulus. This can be localised to one area or generalised and may include: rash, itching, hives, swelling, difficulty breathing, and/or low blood pressure. (27 Sep 1997) |
| allergic rhinitis | <immunology> An inflammatory response in the nasal passages to an allergic stimulus. Often includes: nasal congestion, sneesing, runny or itchy nose. (27 Sep 1997) |
| allergic rhinitis, perennial | Allergic rhinitis (hayfever) that occurs throughout the year. (12 Dec 1998) |
| allergic salute | The person with allergic rhinitis (hayfever) often rubs his/her nose using the index finger. This is the so-called allergic salute. (12 Dec 1998) |
| alveolitis, extrinsic allergic | Conditions in which inhalation of organic dusts results in hypersensitivity reactions at the alveolar level, associated with the production of precipitins. (12 Dec 1998) |
| anti-allergic agents | Agents that are used to treat allergic reactions. most of these drugs act by preventing the release of inflammatory mediators or inhibiting the actions of released mediators on their target cells. (12 Dec 1998) |
| anti-allergic and respiratory system agents | A collective term for drugs used to treat allergic reactions as well as those drugs that produce an effect on the respiratory system. (12 Dec 1998) |
| aspergillosis, allergic bronchopulmonary | Aspergillosis of the lung occurring in an individual with long-standing bronchial asthma. It is characterised by pulmonary infiltrates, eosinophilia, elevated serum IgE and immediate type skin reactivity to aspergillus antigen. (12 Dec 1998) |
| vasculitis, allergic cutaneous | Vasculitis due to allergic reaction, marked by such cutaneous lesions as papules, macules, vesicles, urticarial wheals, purpura, and small ulcers, and accompanied by itching and usually a slight fever and malaise. (12 Dec 1998) |
| reaction, allergic | A reaction that occurs when the immune system attacks a usually harmless substance (an allergen) that gains access to the body. The immune system calls upon a protective substance called immunoglobulin e (IgE) to fight these invading allergic substances ( allergens). Even though everyone has some IgE, an allergic person has an unusually large army of these IgE defenders -in fact, too many for their own good. This army of IgE antibodies attacks and engages the invading army of allergic substances of allergens. As is often the case in war, innocent bystanders are affected by this battle. These innocent bystanders are special cells called mast cells. These cells are frequently injured during the warring of the IgE antibodies and the allergic substances. When a mast cell is injured, it releases a variety of strong chemicals including histamine into the tissues and blood that frequently cause allergic reactions. These chemicals are very irritating and cause itching, swelling, and fluid leaking from cells. These allergic chemicals can cause muscle spasm and can lead to lung and throat tightening as is found in asthma and loss of voice. (12 Dec 1998) |
