| erythema multiforme major | <syndrome> This is a severe form of allergic reaction that most often results from a medication (for example penicillins). The rash can be generalised and even appear on the palms of the hands and soles of the feet. Stevens-Johnson syndrome is considered to be a variant of erythema multiforme that results in the formation of bullous (blebs) lesions on the soles of the feet, palms and inside the mouth. Stevens-Johnson syndrome may also occur in association with some viral infections and Mycoplasma infections. (27 Sep 1997) |

| zygomaticus major | <anatomy, muscle> Origin, zygomatic bone anterior to temporozygomatic suture; insertion, muscles at angle of mouth; action, draws upper lip upward and laterally; nerve supply, facial. Synonym: musculus zygomaticus major, greater zygomatic muscle, musculus zygomaticus. (05 Mar 2000) |
| forceps major | Occipital radiation of the corpus callosum; that part of the fibre radiation of the corpus callosum which bends sharply backward into the occipital lobe of the cerebrum. Synonym: forceps major, forceps posterior, occipital part of corpus callosum, pars occipitalis corporis callosi. (05 Mar 2000) |
| fossa scarpae major | A triangular space at the upper part of the thigh, bounded by the sartorius and adductor longus muscles and the inguinal ligament, with a floor formed laterally by the iliopsoas muscle and medially by the pectineus muscle; the branches of the femoral nerve are distributed within the femoral triangle; it is bisected by the femoral vessels, which enter the adductor canal at its apex. Synonym: trigonum femorale, fossa scarpae major, Scarpa's triangle, subinguinal triangle. (05 Mar 2000) |
| fossa supraclavicularis major | The triangle bounded by the clavicle, the omohyoid muscle, and the sternocleidomastoid muscle; it contains the subclavian artery and vein. Synonym: fossa supraclavicularis major, trigonum omoclaviculare, greater supraclavicular fossa, omoclavicular triangle, subclavian triangle. (05 Mar 2000) |
| leishmania major | A parasitic haemoflagellate of the subgenus leishmania leishmania that infects man and animals and causes cutaneous leishmaniasis (leishmaniasis, cutaneous) of the old world. Transmission is by phlebotomus sandflies. (12 Dec 1998) |
| Leishmania tropica major | A parasitic haemoflagellate of the subgenus leishmania leishmania that infects man and animals and causes cutaneous leishmaniasis (leishmaniasis, cutaneous) of the old world. Transmission is by phlebotomus sandflies. (12 Dec 1998) |
| acetone-insoluble antigen | A diphosphatidyl glycerol that is found in the membrane of Treponema pallidum and is the antigen detected by the Wasserman test for syphilis. (18 Nov 1997) |
| allogeneic antigen | Genetic variations of the same antigens within a given species. (05 Mar 2000) |
| antigen | Virus coded cell surface antigens that appear soon after the infection of a cell by virus, but before virus replication has begun. See: early gene. (18 Nov 1997) |
| antigen-antibody complex | The complex formed by the binding of antigen and antibody molecules. The deposition of large antigen-antibody complexes leading to tissue damage causes immune complex diseases. If the antigen is polyvalent the complex may be insoluble. Immune complexes activate complement through the classical pathway. See: glomerulonephritis, Arthus reaction, type III hypersensitivity. (12 Dec 1998) |
| antigen-antibody reaction | The phenomenon, occurring in vitro or in vivo, of antibody combining with antigen of the type that stimulated the formation of the antibody, thereby resulting in agglutination, precipitation, complement fixation, greater susceptibility to ingestion and destruction by phagocytes, or neutralization of exotoxin. See: skin test. (05 Mar 2000) |
| antigen-binding site | <immunology> In immune network theory, an idiotope, an antigenic site of an antibody that is responsible for that antibody binding to an antigenic determinant (epitope). Also used of the site on a ligand molecule to which a cell surface receptor binds. (18 Nov 1997) |
