| aerosinusitis | Sinus troubles, particulaqrly with pain, due to changing atmospheric pressures, as when going up or down in a plane. Also called barosinusitis or sinus barotrauma. (12 Dec 1998) |

| aerosis | Generation of gas in the tissues. Origin: aero-+ G. -osis, condition (05 Mar 2000) |
| aerosol | <pharmacology> A suspension or dispersion of fine particles of a solid or liquid in a gas which can be atomised into a fine mist for inhalation therapy. Often colloids with a gaseous dispersing phase and either liquid (fog) or solid (smoke) dispersed phase; used in fumigation or in inhalation therapy; may contain propellent agents. (25 Jun 1999) |
| aerosol generator | A device for producing airborne suspensions of small particles for inhalation therapy or experimental work; e.g., a La Mer generator, spinning disk, or vibrating reed, each of which produces a monodisperse aerosol. (05 Mar 2000) |
| aerosol propellant | <chemistry> Compressed gases or vapors in a container which, upon release of pressure and expansion through a valve, carry another substance from the container. They are used for cosmetics, household cleaners, and so on. Examples are butanes, carbon dioxide, fluorocarbons, nitrogen, and propane. (25 Jun 1999) |
| aerosolization | Dispersion in air of a liquid material or a solution in the form of a fine mist, usually for therapeutic purposes, especially to the respiratory passages. (05 Mar 2000) |
| aerospace medicine | <study> A field of medicine which specialises in the effects of atmospheric and space flight on human physical and psychological well-being. (09 Oct 1997) |
| aerosphere | The atmosphere. Origin: Aero- + sphere: cf. F. Aerosphere. Source: Websters Dictionary (01 Mar 1998) |
| aerotaxis | An organisms movement toward or away from oxygen as a reaction to its presence. The term is most often used when discussing aerobes (oxygen-using) versus anaerobes (which don't use oxygen). (09 Oct 1997) |
| aerotherapeutics | Treatment of disease by fresh air, by air of different degrees of pressure or rarity, or by air medicated in various ways. (05 Mar 2000) |
| aerotherapy | Treatment of disease by fresh air, by air of different degrees of pressure or rarity, or by air medicated in various ways. (05 Mar 2000) |
| aerotitis | Middle ear problems due to changing atmospheric pressures, as when a plane descends to land. The problems include ear pain, ringing, diminished hearing and, sometimes, dizziness. The word aerotitis (pronounced aer-o-tit-is) is compounded from aer- + otitis meaning inflammation of the ear. Alternate terms for aerotitis: aerotitis media, barotitis, barotitis media, otic barotrauma. (12 Dec 1998) |
| aerotitis media | See Aerotitis. (12 Dec 1998) |
| aerotolerant | Able to survive in the presence of oxygen. This term especially applies to facultative anaerobes, which don't actually require oxygen to live but are not harmed by its presence. (09 Oct 1997) |
| aerotonometer | 1. An instrument for estimating the tension or pressure of a gas. Synonym: tonometer. Origin: aero-+ G. Tonos, tension, + metron, measure (05 Mar 2000) |
