| proto-oncogene proteins c-kit | Tyrosine kinase membrane receptors which are the natural ligands for mast cell growth factor (steel factor). This interaction is crucial for the development of haematopoietic, gonadal, and pigment stem cells. (12 Dec 1998) |
| disaster supplies kit | You and your family can cope best by preparing for disaster before it strikes. One way to prepare is by assembling a Disaster Supplies Kit. Once disaster hits, you won't have time to shop or search for supplies. But if you've gathered supplies in advance, your family can endure an evacuation or home confinement. For useful information, see the MedicineNet site on YOUR FAMILY DISASTER SUPPLIES KIT. (12 Dec 1998) |

| kit | <oncogene> An oncogene, identified in feline sarcoma, encoding a tyrosine protein kinase that acts on stem cell factor. (18 Nov 1997) |
| kit fox | <zoology> Kit fox, a small burrowing fox (Vulpes velox), inhabiting the region of the Rocky Mountains. It is brownish gray, reddish on the breast and flanks, and white below. Called also swift fox. (11 Mar 1998) |
| 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.

| asthma crystals | Crystal's in the shape of elongated double pyramids, formed from eosinophils, found in the sputum in bronchial asthma and in other exudates or transudates containing eosinophils. Synonym: asthma crystals, Charcot-Neumann crystals, Charcot-Robin crystals, Leyden's crystals. (05 Mar 2000) |
| asthma, exercise-induced | Asthma attacks following a period of exercise. Usually the induced attack is short-lived and regresses spontaneously. The magnitude of postexertional airway obstruction is strongly influenced by the environment in which exercise is performed (i.e. Inhalation of cold air during physical exertion markedly augments the severity of the airway obstruction; conversely, warm humid air blunts or abolishes it). (12 Dec 1998) |
| asthma-weed | Synonym: lobelia. Synonym: Euphorbia pilulifera. (05 Mar 2000) |
| atopic asthma | Bronchial asthma due to atopy. (05 Mar 2000) |
| bronchial asthma | A condition of the lungs in which there is widespread narrowing of airways, varying over short periods of time either spontaneously or as a result of treatment, due in varying degrees to contraction (spasm) of smooth muscle, oedema of the mucosa, and mucus in the lumen of the bronchi and bronchioles; these changes are caused by the local release of spasmogens and vasoactive substances (e.g., histamine, or certain leukotrienes or prostaglandins) in the course of an allergic process. (05 Mar 2000) |
| bronchitic asthma | Asthma precipitated by bronchitis. Synonym: catarrhal asthma. (05 Mar 2000) |
| cardiac asthma | An asthmatic attack, the bronchoconstriction being secondary to the pulmonary congestion and oedema of left ventricular failure. (05 Mar 2000) |
