| immune complex diseases | Diseases characterised by the presence of immune complexes in body fluids. Hypersensitivity of the Arthus type and serum sickness are examples. (18 Nov 1997) |
|---|---|
| immune complex disorder | An immunologic category of diseases evoked by the deposition of antigen-antibody or antigen-antibody-complement complexes on cell surfaces, with subsequent involvement of breakdown products of complement, platelets, and polymorphonuclear leukocytes, and development of vasculitis; nephritis is common. Arthus phenomenon and serum sickness are classic examples, but many other disorders, including most of the connective tissue disease's, may belong in this immunologic category; immune complex disease's can also occur during a variety of disease's of known aetiology, such as subacute bacterial endocarditis. See: autoimmune disease. Synonym: immune complex disorder, type III hypersensitivity reaction. (05 Mar 2000) |
| immune complex glomerulonephritis | Immune complexes are deposited in the renal glomerulus where they bind complement and initiate an inflammatory process attracting neutrophils and macrophages resulting in an alteration of the basement layer of the kidney. The disease state can lead to ultimate destruction of the glomerulus and renal failure. (05 Mar 2000) |
| immune complex nephritis | An immune complex disease resulting from glomerular deposits, as in systemic lupus erythematosus. (05 Mar 2000) |
| QRS complex | <cardiology> The deflections in an electrocardiographic tracing and represent ventricular activity of the heart. (13 Nov 1997) |
| inferiority complex | A sense of inadequacy which is expressed in extreme shyness, diffidence, or timidity, or as a compensatory reaction in exhibitionism or aggressiveness. (05 Mar 2000) |
| initiation complex | Complex between mRNA, 30S ribosomal subunit and formyl methionyl tRNA that requires GTP and initiation factors to function. (18 Nov 1997) |
| iron-dextran complex | <chemical> Iron dextran. A complex of ferric oxyhydroxide with dextrans of 5000 to 7000 daltons in a viscous solution containing 50 mg/ml of iron. It is supplied as a parenteral preparation and is used as a haematinic. (goodman and gilman's the pharmacological basis of therapeutics, 8th ed, p1292) Pharmacological action: haematinics. Chemical name: Iron dextran (12 Dec 1998) |
| iron succinyl milk protein complex | <chemical> Soluble iron complex with 5% iron content produced by reacting succinylated milk protein and ferric chloride Synonym: iron succinyl protein complex, itf 282, itf-282 (05 Dec 1998) |
| isodiphasic complex | A diphasic complex whose positive and negative deflections are approximately equal. Synonym: equiphasic complex. (05 Mar 2000) |
| oedipus complex | Attachment of the child to the parent of the opposite sex, accompanied by envious and aggressive feelings toward the parent of the same sex. (12 Dec 1998) |
| Ornithodoros moubata complex | A group of four species in Africa; the taxonomy and ecology of this complex is of great significance because its members are vectors of relapsing fever spirochetes; members of the complex include Ornithodoros moubata (various hosts), Ornithodoros compactus (tortoises), Ornithodoros apertus (porcupines), and Ornithodoros porcinus (warthogs); a domestic subspecies of Ornithodoros porcinus, in turn, forms three strains that feed chiefly on humans, fowl, and swine. (05 Mar 2000) |
| ostiomeatal complex | Point where the frontal and maxillary sinuses normally drain into the nasal cavity; obstruction produces inflammation of affected sinus cavities. Synonym: ostiomeatal unit. (05 Mar 2000) |
| Tacaribe complex | <virology> Group of 8 Arenaviridae isolated in s.America from bats. (18 Nov 1997) |
| Tacaribe complex of viruses | A group of arenaviruses that includes the antigenically interrelated arboviruses Amapari, Junin, Latino, Machupo, Parana, Pichinde, Tacaribe, and Tamiami. (05 Mar 2000) |
