| international system of units | A system of physical units in which the fundamental quantities are length, time, mass, electric current, temperature, luminous intensity, and amount of substance, and the corresponding units are the meter, second, kilogram, ampere, kelvin, candela, and mole. The system has been given official status and recommended for universal use by the general conference on weights and measures. (12 Dec 1998) |

| international unit | The amount of a substance, such as a drug, hormone, vitamin, enzyme, etc., that produces a specific effect as defined by an international body and accepted internationally; e.g., for an enzyme it is umole of product formed (or substrate consumed) per minute. Synonym: unit. (05 Mar 2000) |
| Leiter International Performance Scale | A nonverbal (performance) test for measuring intelligence which contains norms for each age between 2 and 18; originally developed as a method of assessing the comparative intellectual abilities of Caucasian, Chinese, and Japanese children, but now occasionally used for assessing slow learners and those who are blind, deaf, or verbally handicapped.

| radiation injuries, experimental | Harmful effects of exposure to ionizing or non-ionizing radiation produced experimentally in chordates. (12 Dec 1998) |
| games, experimental | Games designed to provide information on hypotheses, policies, procedure or strategies. (12 Dec 1998) |
| psychology, experimental | The branch of psychology which seeks to learn more about the fundamental causes of behaviour by studying various psychologic phenomena in controlled experimental situations. (12 Dec 1998) |
| neuritis, experimental allergic | An autoimmune demyelinating disorder of peripheral nerves produced by injection of peripheral nerve tissue protein. (12 Dec 1998) |
| implants, experimental | Artificial substitutes for body parts and materials inserted into organisms during experimental studies. (12 Dec 1998) |
| experimental | 1. Of, relating to or based on experience: empirical. 2. Of a disease: intentionally produced especially in laboratory animals for the purpose of study. (18 Nov 1997) |
| experimental allergic encephalitis | <pathology> An autoimmune disease that can be induced in various experimental animals by the injection of homogenised brain or spinal cord in Freund's adjuvant. The antigen appears to be a basic protein present in myelin and the response is characterised by focal areas of lymphocyte and macrophage infiltration into the brain, associated with demyelination and destruction of the blood-brain barrier. Sometimes used as a model for demyelinating diseases, although whether this is entirely justifiable is not clear. (18 Nov 1997) |

| experimental error | The total error of measurement ascribed to the conduct of an empirical observation. It is commonly expressed as the standard deviation of replicated experiments. There may be many components, including those in the sampling procedure, the measurements, injudicious choice of a model, observer bias, etc. (05 Mar 2000) |
