perennial allergic rhinitis
| extrinsic pathway | <haematology> Initiation of blood clotting as a result of factors released from damaged tissue, as opposed to contact with a foreign surface (the intrinsic pathway). Tissue thromboplastin (Factor III) in conjunction with Factor VII proconvertin) will activate Factor X that, once activated, converts prothrombin to thrombin. (27 Jun 1999) |
|---|---|
| extrinsic protein | <protein> A protein found in a cell or tissue which came from somewhere else (other than the cell or tissue in which it is found). (09 Oct 1997) |
| extrinsic proteins | Pathways that can be easily removed from a biomembrane (e.g., by altering the pH or the ionic strength). Synonym: extrinsic proteins. (05 Mar 2000) |
| extrinsic sphincter | A sphincter provided by circular muscular fibres extraneous to the organ. (05 Mar 2000) |
| allergic | <immunology> Pertaining to, caused by, affected with or of the nature of allergy. (18 Nov 1997) |
| allergic angiitis | An acute form of vasculitis which may affect the skin only, but also may involve other organs, with a polymorphonuclear infiltrate in the walls of and surrounding small (dermal) vessels. Nuclear fragments are formed by karyorrhexis of the neutrophils. See: leukocytoclastic vasculitis. Synonym: allergic angiitis, hypersensitivity vasculitis. (05 Mar 2000) |
| allergic asthma | <chest medicine> A disease process that is characterised by paradoxical narrowing of the bronchi (lung passageways) making breathing difficult. Treatment includes bronchodilators which are given orally or delivered as an aerosol (inhaled). Corticosteroids are reserved for more difficult cases. Symptoms include wheezing, difficulty breathing (particularly exhaling air) and tightness in the chest. Factors which can exacerbate asthma include rapid changes in temperature or humidity, allergies, upper respiratory infections, exercise, stress or smoke (cigarette). See: status asthmaticus. (27 Sep 1997) |
| allergic bronchopulmonary aspergillosis | <radiology> ABPA: Aspergillus fumigatus hypersensitivity, mucoid impaction of bronchi distal to lobar bronchus, mucus plugs contain fungi, eosinophils, XR: Y-shaped density (mucus plug wedged in bronchi) (12 Dec 1998) |
| allergic conjunctivitis | <ophthalmology> An inflammatory condition of the conjunctiva secondary to an allergic stimulus. Common symptoms include itchy, red and tearing eyes (27 Sep 1997) |
| allergic contact dermatitis | A delayed type IV allergic reaction of the skin with varying degrees of erythema, oedema, and vesiculation resulting from cutaneous contact with a specific allergen. Synonym: contact allergy. (05 Mar 2000) |
| allergic coryza | A rhinitis in an allergic individual due to the presence of an agent to which he is hypersensitive. (05 Mar 2000) |
| allergic eczema | Macular, papular, or vesicular eruption due to an allergic reaction. (05 Mar 2000) |
| 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) |
