Antihistamine drug now withdrawn from the market in many countries because of rare but potentially fatal side effects.

Flower petals are joined near the base and stamens alternate with the corolla lobes. The common name of daisy refers to several genera of this family including Aster; CHRYSANTHEMUM; RUDBECKIA; TANACETUM.

A form of bronchial disorder with three distinct components: airway hyper-responsiveness (RESPIRATORY HYPERSENSITIVITY), airway INFLAMMATION, and intermittent AIRWAY OBSTRUCTION. It is characterized by spasmodic contraction of airway smooth muscle, WHEEZING, and dyspnea (DYSPNEA, PAROXYSMAL).
Asthmatic adverse reaction (e.g., BRONCHOCONSTRICTION) to conventional NSAIDS including aspirin use.
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).
Asthma attacks caused, triggered, or exacerbated by OCCUPATIONAL EXPOSURE.
Unequal or irregular curvature of the CORNEA (Corneal astigmatism) and/or the EYE LENS (Lenticular astigmatism) resulting in REFRACTIVE ERROR.
A plant genus in the family FABACEAE, subfamily Papilionaceae, order Fabales, subclass Rosidae. Many of the species are associated with poisoning of grazing animals. Some of the species are used medicinally.

Agents, usually topical, that cause the contraction of tissues for the control of bleeding or secretions.
A class of large neuroglial (macroglial) cells in the central nervous system - the largest and most numerous neuroglial cells in the brain and spinal cord. Astrocytes (from star cells) are irregularly shaped with many long processes, including those with end feet which form the glial (limiting) membrane and directly and indirectly contribute to the BLOOD-BRAIN BARRIER. They regulate the extracellular ionic and chemical environment, and reactive astrocytes (along with MICROGLIA) respond to injury.
Neoplasms of the brain and spinal cord derived from glial cells which vary from histologically benign forms to highly anaplastic and malignant tumors. Fibrillary astrocytomas are the most common type and may be classified in order of increasing malignancy (grades I through IV). In the first two decades of life, astrocytomas tend to originate in the cerebellar hemispheres; in adults, they most frequently arise in the cerebrum and frequently undergo malignant transformation.
