See GABA.... gamma aminobutyric acid

Short-wavelength penetrating electromagnetic rays produced by some radioactive compounds. More powerful than X-rays, they are used in certain RADIOTHERAPY treatments and to sterilise some materials.... gamma rays

Gamma-globulin describes a group of proteins present in the blood PLASMA. They are characterised by their rate of movement in an electrical ?eld, and can be separated by the process of ELECTROPHORESIS. Most gamma-globulins are IMMUNOGLOBULINS. Gamma-globulin injection provides passive or active immunity against HEPATITIS A. (See also GLOBULIN; IMMUNITY; IMMUNOLOGY.)... gamma-globulin

A drug that is used in the treatment of PEDICULOSIS and SCABIES.... gamma benzene hexachloride

A polyunsaturated fatty acid; an essential ingredient in the body’s production of prostaglandins. Present naturally in mother’s milk. The body produces GLA from linoleic acid present in food as an essential fatty acid (EFA). Vital to growth, cell structure and cardiac health. Sources: Evening Primrose oil; Sunflower seed oil, Borage and Blackcurrant. Preparations from the fermentation of rotten carrots. Helps lower blood pressure and prevent cholesterol build-up in the blood. ... gamma linolenic acid (gla)

an apparatus that detects gamma rays emitted by radioactive isotopes that have been introduced into the body as *tracers. It contains an activated sodium iodide crystal (see scintillator) and a large array of photomultiplier tubes. Using lead *collimators, the position of the source of the radioactivity can be plotted and displayed on a TV monitor or photographic film (see scintigram).... gamma camera

any of a class of proteins, present in the blood *plasma, identified by their characteristic rate of movement in an electric field (see electrophoresis). Almost all gammaglobulins are *immunoglobulins. Injection of gammaglobulin provides temporary protection against *hepatitis A and reduces the incidence of coronary artery involvement in *Kawasaki disease. Infusions of gammaglobulin are used to treat immunodeficiencies or immune-mediated disorders, such as autoimmune haemolytic *anaemia or *idiopathic thrombocytopenic purpura. See also globulin.... gammaglobulin

a device that allows high doses of radiation in the form of gamma rays to be accurately focused on pathological tissue, with less risk of damaging adjacent normal tissue compared with conventional radiotherapy. Multiple cobalt-60 sources deliver the gamma irradiation. The device is used in the treatment of vestibular schwannomas, certain brain tumours, vascular lesions of the brain, trigeminal neuralgia, and some forms of epilepsy.... gamma knife
