| clorazepate | 7-Chloro-2,3-dihydro-2-oxo-5-phenyl-1H-1,4-benzodiazepine-3-carboxylate;the mono-or dipotassium salt is used as an anti-anxiety agent; a benzodiazepine prodrug for nordiazepam. (05 Mar 2000) |
| clorazepate dipotassium | <chemical> A water-soluble benzodiazepine derivative effective in the treatment of anxiety. It has also muscle relaxant and anticonvulsant actions. Pharmacological action: anti-anxiety agents, anticonvulsants, gaba modulators. Chemical name: 1H-1,4-Benzodiazepine-3-carboxylic acid, 7-chloro-2,3-dihydro-2-oxo-5-phenyl-, monopotassium salt, compd. With potassium hydroxide (K(OH)) (1:1) (12 Dec 1998) |
| clorgyline | <chemical> An antidepressive agent and monoamine oxidase inhibitor related to pargyline. Pharmacological action: antidepressive agents, monoamine oxidase inhibitors. Chemical name: 2-Propyn-1-amine, N-(3-(2,4-dichlorophenoxy)propyl)-N-methyl- (12 Dec 1998) |
| clorprenaline hydrochloride | O-chloro-alpha-(isopropylaminomethyl)benzyl alcohol hydrochloride;a bronchodilator. Synonym: isoprophenamine hydrochloride. (05 Mar 2000) |
| close bite | A small distance between the maxillary and mandibular arches. Synonym: close bite. (05 Mar 2000) |
| close contact infection | <epidemiology> An infection which requires close contact, other than sexual contact, between susceptible and infectious individuals, for transmission. (05 Dec 1998) |
| closed anaesthesia | Inhalation anaesthesia in which there is total rebreathing of all exhaled gases, except carbon dioxide which is absorbed; gas flow into the anaesthetic circuit consists only of oxygen, in amounts equal to the patient's metabolic consumption, plus small amounts of other gases (e.g., nitrous oxide) which undergo continued uptake by and distribution in the patient. (05 Mar 2000) |
| closed bite | <dentistry> A malocclusion where your upper teeth cover your lower teeth when you bite down. This is also called a deep bite. (08 Jan 1998) |
| closed chain compound | Any compound in which the constituent atoms, or any part of them, form a ring. Used mainly in organic chemistry where: 1) numerous compound's contain rings of carbon atoms (carbocyclic compound's) or carbon atoms plus one or more atoms of other types (heterocyclic compound's), usually nitrogen, oxygen, or sulfur; 2) where the atoms in the ring are all of the same element (homocyclic or isocyclic compound); 3) where the ring is saturated or contains nonconjugated double bonds (alicyclic compound), the compound is similar in properties to the corresponding acyclic compound (e.g., cyclohexane resembles hexane); 4) where the ring contains conjugated double bonds in a closed loop in which there are 4n + 2 (where n is an integer) delocalised π electrons (Huckel's rule) (aromatic compound; e.g., benzene, pyridine), it is more stable than the corresponding saturated ring and exhibits unusual chemical properties characteristic of itself and not of other types of rings or of acyclic compound's. These aromatic compounds have the ability to sustain an induced ring current. Synonym: closed chain compound, ring compound. (05 Mar 2000) |
| closed chest massage | Rhythmic compression of the heart between sternum and spine by depressing the lower sternum backward with the heels of the hands, the patient lying supine. Synonym: external cardiac massage. (05 Mar 2000) |
| closed circle | A circuit for administration of an inhalation anaesthetic in which there is complete rebreathing with carbon dioxide absorption. (05 Mar 2000) |
| closed circuit method | A method for measuring oxygen consumption in which the subject rebreathes an initial quantity of oxygen through a carbon dioxide absorber and the decrease in the volume of oxygen being rebreathed is noted. (05 Mar 2000) |
| closed comedo | A comedo with a narrow or obstructed opening on the skin surface; closed comedo's may rupture, producing a low-grade dermal inflammatory reaction. Synonym: whitehead. (05 Mar 2000) |
| closed dislocation | A dislocation not complicated by an external wound. Synonym: simple dislocation. (05 Mar 2000) |
