| effective half-life | <radiobiology> Time required for a radioactive substance contained in a biological system (such as a person or an animal) to reduce its radioactivity by half, as a combination result of radioactive decay and biological elimination from the system. (09 Oct 1997) |

| effective osmotic pressure | That part of the total osmotic pressure of a solution that governs the tendency of its solvent to pass across a boundary, usually a semipermeable membrane; it is commonly represented by the product of the total osmotic pressure of the solution and the ratio (corrected for activities) of the number of dissolved particles that do not permeate the bounding membrane to the total number of particles in the solution; equivalent in meaning to tonicity; commonly expressed in equivalent units of osmolality rather than pressure per se.

| effective renal blood flow | The amount of blood flowing to the parts of the kidney that are involved with production of constituents of urine. (05 Mar 2000) |
| effective renal plasma flow | <physiology> The amount of plasma flowing to the parts of the kidney that have a function in the production of constituents of urine; the clearance of substances such as iodopyracet and p-aminohippuric acid, assuming that the extraction ratio in the peritubular capillaries is 100%. It is the amount of plasma perfusing the kidney tubules per unit time, generally measured by p-aminohippurate clearance. It should be differentiated from renal plasma flow which is approximately 10% greater than the effective renal plasma flow. (07 Mar 2000) |
| effective temperature | A comfort index or scale which takes into account the temperature of air, its moisture content, and movement. (05 Mar 2000) |
| effective temperature index | A composite index of environmental comfort which is compared after exposure to different combinations of air temperature, humidity, and movement. (05 Mar 2000) |
| anaemia, refractory | Anaemia (a shortage of red blood cells) unresponsive to treatment. (12 Dec 1998) |
| anaemia, refractory, with excess of blasts | Chronic refractory anaemia with granulocytopenia, and/or thrombocytopenia. Myeloblasts and progranulocytes constitute 5 to 40 percent of the nucleated marrow cells. (12 Dec 1998) |
| refractory | Not readily yielding to treatment. Origin: L. Refractorius (18 Nov 1997) |
| refractory anaemia | <haematology> A form of myelodysplasia which primarily affects the red cell production by the bone marrow. In some cases the developing red cells show an internal ring of iron granules. These cells are called sideroblasts. Refractory anaemia and refractory anaemia with sideroblasts are the most common forms of myelodysplasia. Origin: Gr. Haima = blood (13 Nov 1997) |
| refractory anaemia with excess blasts | <haematology> A form of myelodysplasia characterised by the build up of immature white blood cells (blasts) in the bone marrow. If the immature cells are particularly numerous it may indicate a chance of transformation to acute leukaemia and the condition is called refractory anaemia with excess blasts in transformation (RAEBt). Acronym: RAEB (13 Nov 1997) |
| refractory cast | A cast made of material that will withstand the high temperatures of metal casting or soldering without disintegrating. Synonym: investment cast. (05 Mar 2000) |
| refractory flask | A metal tube in which a refractory mold is made for casting metal dental restorations or appliances. Synonym: casting flask, casting ring. (05 Mar 2000) |
| refractory lining | A lining, usually of ceramic, capable of resisting and maintaining high temperatures. (05 Dec 1998) |
| refractory rickets | Rickets that does not respond to treatment with usual doses of vitamin D and adequate dietary calcium and phosphorus. Most often due to inherited renal tubular disorder e.g., Fanconi syndrome. Renal rickets, a form of rickets occurring in children in association with and apparently caused by renal disease with hyperphosphatemia. Synonym: pseudorickets, renal fibrocystic osteosis, renal infantilism, renal osteitis fibrosa. (05 Mar 2000) |
