| dose-response relationship, immunologic | A specific immune response elicited by a specific dose of an immunologically active substance or cell in an organism, tissue, or cell. (12 Dec 1998) |
|---|---|
| dose-response relationship, radiation | The relationship between the dose of administered radiation and the response of the organism or tissue to the radiation. (12 Dec 1998) |
| immunologic high dose tolerance | Induction of tolerance by exposure to large amounts of protein antigens. (05 Mar 2000) |
| initial dose | A comparatively large dose given at the beginning of treatment to get the patient under the influence of the drug. Synonym: loading dose. (05 Mar 2000) |
| integral dose | The total energy absorbed by the body, the product of the mass of tissue irradiated and the absorbed dose; unit, the gram rad. (05 Mar 2000) |
| optimum dose | The dose of a drug or radiation that will produce the desired effect with minimum likelihood of undesirable symptoms. (05 Mar 2000) |
| therapeutic dose | The quantity of any substance required to effect the cure of a disease or that will correct the manifestations of a deficiency of a particular factor in the diet, effective dose used with therapeutically applied compounds. Synonym: therapeutic dose. (05 Mar 2000) |
| effective dose | The dose that produces the desired effect; when followed by a subscript (generally "ED50"), it denotes the dose having such an effect on a certain percentage (e.g., 50%) of the test animals; ED50 is the median effective dose, in radiation protection, the sum of the equivalent doses in all tissues and organs of the body weighted for tissue effects of radiation. The unit of effective dose is the sievert (Sv), epilation dose, the minimum amount of radiation sufficient to produce hair loss, usually in 10 to 14 days. (05 Mar 2000) |
| tissue culture infectious dose | The quantity of a cytopathogenic agent, such as a virus, that will produce a cytopathic effect in 50% of the cultures inoculated. (05 Mar 2000) |
| tolerance dose | The largest dose of a remedy that can be accepted without the production of injurious symptoms. (05 Mar 2000) |
| equianalgesic dose | The qualitative ratio between actual milligram potency of comparable analgesics required to achieve the equivalent therapeutic effect. (05 Mar 2000) |
| equivalent dose | In radiation protection, the absorbed dose averaged over a tissue or organ and weighted for the quality of the radiation of interest. The unit of equivalent dose is the sievert. (05 Mar 2000) |
| exit dose | The exposure dose of radiation leaving a body opposite the portal of entry. (05 Mar 2000) |
| exposure dose | The radiation dose, expressed in roentgens, delivered at a point in free air. Synonym: air dose. (05 Mar 2000) |
| unit dose | Occurring in or using a single dose, seen as a standard of measurement. (18 Nov 1997) |
