| aseptic bursitis | Inflammation of a bursa that is not caused by infection. A bursa is a closed fluid-filled sac that functions as a gliding surface to reduce friction between tissues of the body. When the bursa becomes inflamed, the condition is known as bursitis. most commonly this is not an infectious condition (aseptic bursitis). (12 Dec 1998) |
| aseptic fever | Fever accompanied by malaise due to absorption of dead but not infected tissue following an injury. (05 Mar 2000) |
| aseptic meningitis | <neurology> A meningeal reaction in the cerebrospinal fluid sometimes occurring in the absence of an infecting organism. It can be due to a virus, foreign substance, diagnostic or therapeutic procedure, or to a tumour or a septic focus within the skull or spinal canal. <virology> When due to a virus, it is seen most often in those under 30 years of age. Peak time for infection is in late summer. Majority of cases are caused by the Coxsackie and echovirus. (21 Jun 1999) |
| aseptic necrosis | <orthopaedics, pathology> Condition in which poor blood supply to an area of bone leads to bone death. Also called avascular necrosis and osteonecrosis. (12 Dec 1998) |
| aseptic surgery | The performance of an operation with sterilised hands, instruments, etc., and utilizing precautions against the introduction of infectious microorganisms from without. (05 Mar 2000) |
| aseptic technique | <procedure> A method used by microbiologists and clinicians to keep cultures, sterile instruments and media, and people free of microbial contamination. (09 Oct 1997) |
| bursitis, aseptic | A bursa is a closed fluid-filled sac that functions as a gliding surface to reduce friction between tissues of the body. When the bursa becomes inflamed, the condition is known as bursitis. most commonly this is not an infectious condition (aseptic bursitis). (12 Dec 1998) |
| epiphysial aseptic necrosis | Aseptic necrosis of bony epiphyses, probably due to ischemia; it may affect the upper end of the femur (Legg-Calve-Perthes disease), the tibial tubercle (Osgood-Schlatter disease), the tarsal navicular bone or the patella (Kohler's disease), the second metatarsal head (Freiberg's disease), vertebral bodies (Scheuermann's disease), or the capitellum of the humerus (Panner's disease).

| amaranth solution | A 1% solution of amaranth (trisodium naphthol sulfonic acid), a synthetic vivid red dye, stable in acid and intensified in sodium hydroxide solution; used as a red or pink colourant in liquid pharmaceuticals. (05 Mar 2000) |
| aqueous solution | <chemistry> A solution in which water is the dissolving medium or solvent. (09 Jan 1998) |

| Benedict's solution | <chemistry> An aqueous solution of sodium citrate, sodium carbonate, and copper sulfate which changes from its normal blue colour to orange, red, or yellow in the presence of a reducing sugar such as glucose. See: Benedict's test for glucose. (14 Aug 2000) |
