| anti-infective | <pharmacology> Substances capable of killing infectious agents or of preventing them from spreading and causing infection. (20 Jun 2000) |
|---|---|
| anti-infective agents, local | Substances used on humans and other animals that destroy harmful microorganisms or inhibit their activity. They are distinguished from disinfectants, which are used on inanimate objects. (12 Dec 1998) |
| anti-infective agents, quinolone | A group of synthetic antimicrobial agents which usually contain a 4-quinolinone ring structure. A few compounds belonging to this group have related nitrogen heterocyclic ring structures such as naphthyridine or phthalazine groups. All compounds in this group are substituted with an oxo group at the 4-position. The second-generation quinolones are also substituted with a 1-piperazinyl group at the 7-position and a fluorine moiety at the 6-position. The quinolones inhibit the a subunit of DNA gyrase and thus interfere with the ability of the enzyme to repair bacterial DNA breaks during replication. The compounds have a broad spectrum of activity against a variety of aerobic bacteria. (12 Dec 1998) |
| anti-infective agents, urinary | Substances capable of killing agents causing urinary tract infections or of preventing them from spreading. (12 Dec 1998) |
| anti-inflammatory | Counteracting or suppressing inflammation. (18 Nov 1997) |
| anti-inflammatory agent | Agents that counteract or suppress the inflammatory process. An antirheumatic agent or inflammation mediator, both endogenous and exogenous substances used to counteract the inflammatory process or alleviate or prevent rheumatic diseases, and the compounds that mediate the inflammation process. (12 Dec 1998) |
| anti-inflammatory agent, non-steroidal | Anti-inflammatory agents that are not steroids. In addition to anti-inflammatory actions, they have analgesic, antipyretic, and platelet-inhibitory actions. They are used primarily in the treatment of chronic arthritic conditions and certain soft tissue disorders associated with pain and inflammation. They act by blocking the synthesis of prostaglandins by inhibiting cyclooxygenase, which converts arachidonic acid to cyclic endoperoxides, precursors of prostaglandins. Inhibition of prostaglandin synthesis accounts for their analgesic, antipyretic, and platelet-inhibitory actions; other mechanisms may contribute to their anti-inflammatory effects. Certain nsaids also may inhibit lipoxygenase enzymes or phospholipase c or may modulate T-cell function. (ama drug evaluations annual, 1994, p 1814-5) (12 Dec 1998) |
| anti-inflammatory agent, steroidal | Steroidal agents capable of suppressing or counteracting the inflammatory process by acting on body mechanisms, without directly antagonizing the causative agents. (12 Dec 1998) |
| anti-inflammatory agent, topical | Anti-inflammatory agent that are applied to the skin and whose pharmacological effect only occurs at the area of application. (12 Dec 1998) |
| anti-insulin | A factor, usually an antibody, which antagonises the action of insulin. (05 Mar 2000) |
| anti-insulin antibody | A serologic blood test that is used to detect antibodies to insulin. This test is performed in insulin dependent diabetics who exhibit insulin resistance. The presence of antibodies denotes a positive result. (27 Sep 1997) |
| anti-kidney serum nephritis | Experimental glomerulonephritis produced by injection of antiserum to kidney. (05 Mar 2000) |
| anti-microsomal antibodies | Anti-microsomal antibodies or anti-thyroid microsomal antibodies measure for the presence of antibody to thyroid microsomes. The anti-microsomal antibody or microsomal antibody test is used to diagnose conditions such as Hashimoto's thyroiditis and other autoimmune disorders. (27 Sep 1997) |
| anti-mitochondrial antibodies | A special serologic test that measures the level of antibodies to a particular portion of a cell (mitochondria). (27 Sep 1997) |
| anti-Monson curve | In dentistry, a curve of occlusion which is convex upward. Synonym: anti-Monson curve. (05 Mar 2000) |
