| concentration-effect curve | <pharmacology> This is a graph produced to show the relationship between the exposure concentration of a drug or other foreign chemical and the magnitude of the graded effect that it produces. (05 Jan 1998) |
|---|---|
| concentration gradient | <chemistry> A column of liquid in which the density varies continually with position, usually as a consequence of variation of concentration of a solute. Such gradients may be established by progressive mixing of solutions of different density as for example: sucrose gradients) or by centrifuge induced redistribution of solute (as for caesium chloride gradients). Density gradients are widely used for centrifugal and gravity induced separations of cells, organelles and macromolecules. The separations may exploit density differences between particles or primarily differences in size, in which latter case the function of the gradient is chiefly to stabilise the liquid column against mixing.

| concentration-response curve | <pharmacology> This is a graph produced to show the relation between the exposure concentration of a drug (or other chemical) and the degree of response it produces, as measured by the percentage of the exposed population showing a defined, often quantal, effect. (05 Jan 1998) |
| critical concentration | <chemistry> The minimum concentration of units needed before a biological polymer will form. Examples of biopolymers are microtubules from tubulin units, polypeptides from amino acid units, polysaccharides from simple sugar units, etc. (09 Oct 1997) |
| critical dissolved oxygen concentration | <biology> The minimum concentration of oxygen in the water needed for the growth of a culture which has been submerged, where oxygen is the limiting factor to the growth of the culture. (09 Oct 1997) |
| critical micelle concentration | The concentration at which an amphipathic molecule (e.g., a phospholipid) will form a micelle. (05 Mar 2000) |
| immediately dangerous to life concentration | <radiobiology> This is a regulatory value defined as the maximum exposure concentration in the workplace from which one could escape within 30 minutes without suffering symptoms which would interfere with escaping and without suffering any irreversible health effects. (04 Nov 1997) |
| osmolar concentration | The concentration of osmotically active particles in solution expressed in terms of osmoles of solute per liter of solution. Osmolality is expressed in terms of osmoles of solute per kilogram of solvent. (12 Dec 1998) |
| urinary concentration test | A test of renal tubular function whereby the patient is dehydrated for a measured period of time and the specific gravity of the urine is subsequently determined. (05 Mar 2000) |
| Fishberg concentration test | A test of renal water conservation; after overnight fluid deprivation, morning urine samples are collected and specific gravity is measured. (05 Mar 2000) |
| amorphous insulin zinc suspension | Sterile suspension of insulin in buffered water for injection, modified by the addition of zinc chloride such that the solid phase of the suspension is amorphous; it contains 40 or 80 units per ml; the duration of action is equivalent to that of insulin injection. Synonym: amorphous insulin zinc suspension, semilente insulin. (05 Mar 2000) |
| butter of zinc | ZnCl2;formerly used as a caustic for the removal of cutaneous cancers, nevi, etc., and in weak solution in the treatment of gonorrhoea and conjunctivitis. Synonym: butter of zinc. (05 Mar 2000) |
| globin zinc insulin | A sterile solution of insulin modified by the addition of zinc chloride and globin; it contains 40 or 80 units per ml; duration of action is about 18 hours. Human insulin, a protein that has the normal structure of insulin produced by the human pancreas, prepared by recombinant DNA techniques and by semisynthetic processes. Immunoreactive insulin (IRI), that portion of insulin in blood measured by immunochemical methods for the hormone; presumed to represent the free (unbound) and biologically active fraction of total blood insulin. Isophane insulin, a modified form of insulin composed of insulin, protamine, and zinc; an intermediately acting preparation used for the treatment of diabetes mellitus. Synonym: NPH insulin. (05 Mar 2000) |
| medicinal zinc peroxide | A mixture of zinc peroxide, zinc carbonate, and zinc hydroxide; a topical disinfectant, astringent, and deodorant. (05 Mar 2000) |
| modified zinc oxide-eugenol cement | Dental cement obtained by mixing zinc oxide and eugenol with one or more additives. (05 Mar 2000) |
