| chloride depletion | Excessive loss of sodium chloride from the body in urine, sweat, etc.; a cause of secondary dehydration. Synonym: chloride depletion. Water depletion, reduction in the total volume of body water; dehydration. (05 Mar 2000) |
| chloride peroxidase | <enzyme> An enzyme that catalyses the chlorination of a range of organic molecules, forming stable carbon-chloride bonds. Chemical name: Chloride:hydrogen-peroxide oxidoreductase Registry number: EC 1.11.1.10 (12 Dec 1998) |
| chloride shift | When CO2 enters the blood from the tissues, it passes into the red blood cell and is converted by carbonate dehydratase to bicarbonate (HCO3-); HCO3- ion passes out into the plasma while Cl- migrates into the red blood cell. Reverse changes occur in the lungs when CO2 is eliminated from the blood. Synonym: Hamburger's phenomenon. (05 Mar 2000) |

(05 Mar 2000) |
| methacholine chloride | <chemical> A slowly hydrolyzed muscarinic agonist. It is used as a parasympathomimetic bronchoconstrictor agent and as a diagnostic aid for bronchial asthma. It has also been used in the treatment of glaucoma and in the treatment of raynaud's syndrome and other vasospastic conditions. Pharmacological action: bronchoconstrictor agent, miotics, muscarinic agonist, parasympathomimetic. Chemical name: 1-Propanaminium, 2-(acetyloxy)-N,N,N-trimethyl- (12 Dec 1998) |
