| crystallins | A heterogeneous family of water-soluble structural proteins found in cells of the vertebrate lens. The presence of these proteins accounts for the transparency of the lens. The family is composed of four major groups, alpha, beta, gamma, and delta, and several minor groups, which are classed on the basis of size, charge, immunological properties, and vertebrate source. Alpha, beta, and delta crystallins occur in avian and reptilian lenses, while alpha, beta, and gamma crystallins occur in all other lenses. (12 Dec 1998) |

| crytotetany | A rather vague disorder recognised more in Europe than in the U.S. Consisting of a number of non-specific complaints, including generalised weakness, hand and foot cramping, distal paresthesia, anxiety, and depression. Some think it is a "normocalcaemic tetany"; others consider it "chronic hyperventilation syndrome." Typically with certain provoking procedures (e.g., limb ischemia, hyperventilation) in which case, obvious tetany develops. See: Trousseau's sign, Chvostek's sign, Erb sign. Synonym: crytotetany, spasmophilia. (05 Mar 2000) |
