| Charcot-Leyden crystals | Crystal's in the shape of elongated double pyramids, formed from eosinophils, found in the sputum in bronchial asthma and in other exudates or transudates containing eosinophils.

| charcot-marie disease | A hereditary motor and sensory neuropathy transmitted as an autosomal dominant trait and characterised by progressive distal wasting and loss of reflexes in the muscles of the legs (occasionally of the arms). Onset is usually in the second to fourth decades. (12 Dec 1998) |
| Charcot-Marie-Tooth disease | <disease> A slowly progressive genetic disorder which is the most common of the inherited peripheral neuropathies, and encompasses a family of disorders characterised by distal muscle weakness and diminished nerve conduction velocity, due to the destruction of nerves with degeneration of the myelin sheath. Features include muscle atrophy in the feet and the legs, progressing to the hands and arms, often with foot drop and a slapping gait. The predominant variety, designated CMT1, is an autosomal dominant disorder caused, in most cases, by duplication of a very large (1.5 Mb) region on chromosome 17p11.2-12. A related condition, hereditary neuropathy with liability to pressure palsies (HNPP), is associated with a large deletion in the same general region. There is no specific treatment for this disorder.

| Charcot-Weiss-Baker syndrome | <syndrome> Stimulation of a hyperactive carotid sinus, causing a marked fall in blood pressure due to vasodilation, cardiac slowing, or both; syncope with or without convulsions or A-V block may occur. Synonym: Charcot-Weiss-Baker syndrome. (05 Mar 2000) |
| Chargaff's rule | In DNA the number of adenine units equals the number of thymine units; likewise, the number of guanine units equals the number of cytosine units. (05 Mar 2000) |

| charge | 1. <physics> A fundamental physical attribute of a particle, which characterises the particle's electromagnetic interaction with other particles and with electric and magnetic fields. 2. Storing energy in a battery or electric capacitor by running a current through it, opposite of discharge. (It is possible to charge most capacitors in either direction, but batteries charge one way, and discharge in the other.) (13 Nov 1997) |
| charge exchange | <radiobiology> Phenomenon in which an ion colliding with a molecule (or an atom) neutralises itself by capturing an electron from the molecule or atom, and transforming the molecule or atom into a positive radical or ion. (13 Nov 1997) |
| charge nurse | A nurse administratively responsible for a designated hospital unit on an 8 hour basis. Synonym: head nurse. (05 Mar 2000) |
| charge transfer | A complex between two organic molecules in which an electron from one (the donor) is transferred to the other (the acceptor), becoming generally distributed throughout the latter; subsequent transfer of a hydrogen atom completes the reduction of the acceptor; such complex's are generally highly coloured and may be so observed, a network of hydrogen bridges at the catalytic centre of certain proteases. Synonym: charge transfer system. (05 Mar 2000) |
| charge transfer complex | A complex between two organic molecules in which an electron from one (the donor) is transferred to the other (the acceptor), becoming generally distributed throughout the latter; subsequent transfer of a hydrogen atom completes the reduction of the acceptor; such complex's are generally highly coloured and may be so observed, a network of hydrogen bridges at the catalytic centre of certain proteases.
