| birch tar oil | Pyroligneous oil obtained by the dry distillation of the wood of Betula alba and rectified by steam distillation; used externally in the treatment of skin diseases. Synonym: birch tar. (05 Mar 2000) |

| rectified optics | <microscopy> Microscope lens system correcting the rotation of polarized light that takes place at high-incidence-angle interfaces between the polarizer and analyser. Rectification provides high extinction for polarized-light and Differential Interference Contrast microscopy at high numerical apertures, thus permitting bifringence or phase retardation combined with high in g low phase. (05 Aug 1998) |
| rectified spirit | <chemical> An organic chemical containing one or more hydroxyl groups. Alcohols can be liquids, semisolids or solids at room temperature. Common alcohols include ethanol (the type found in alcoholic beverages) methanol (found in methylated spirit and can cause blindness and other nervous system damage if ingested) and propanol. (06 May 1997) |
| beechwood tar | A thick, oily, dark brown liquid with the odour of creosote; largely used as a source of creosote. Synonym: beech oil. (05 Mar 2000) |
| birch tar | Pyroligneous oil obtained by the dry distillation of the wood of Betula alba and rectified by steam distillation; used externally in the treatment of skin diseases. Synonym: birch tar. (05 Mar 2000) |
| coal tar | <pharmacology> A byproduct obtained during the breakdown of bituminous coal used in the treatment of some skin diseases (for example psoriasis). (27 Sep 1997) |
| coal tar naphtha | <chemistry> A volatile, very inflammable liquid, contained in the naphtha produced by the destructive distillation of coal, from which it is separated by fractional distillation. The name is sometimes applied also to the impure commercial product or benzole, and also, but rarely, to a similar mixed product of petroleum. The Benzene nucleus or Benzene ring, is a closed chain or ring, consisting of six carbon atoms, each with one hydrogen atom attached, regarded as the type from which the aromatic compounds are derived. Structure: C6H6 Origin: From Benzoin. (06 Aug 1998) |
| pine tar | Obtained by the destructive distillation of the wood of Pinus palustris and other species of Pinus; used internally as an expectorant, and externally in the treatment of skin diseases. Synonym: liquid pitch. (05 Mar 2000) |
| syndrome, tar | TAR stands for Thrombocytopenia (low blood platelets) and aplasia (absence) of the radius (the long bone on the thumb-side of the forearm), features characterizing this syndrome. There is phocomelia more than (flipper-limb) with the thumbs always present. The fibula (the smaller bone in thye lower leg) is often absent. The risk of bleeding from too few platelets is high in early infancy but lessens with age. The condition is inherited in an autosomal recessive trait with one gene (on a non-sex chromosome) coming from each parent to the tar child. Alternative names include more than thrombocytopenia-absent radius syndrome, radial aplasia-thrombocytopenia syndrome, and tetraphocomelia-thrombocytopenia syndrome. (12 Dec 1998) |
| tar | A thick, black, viscous liquid obtained by the distillation of wood, coal, etc, and having a varied composition according to the temperature and material employed in obtaining it. Coal tar. <chemical> Mineral tar, a kind of soft native bitumen. Tar board, a strong quality of millboard made from junk and old tarred rope. Tar water. A cold infusion of tar in water, used as a medicine. The ammoniacal water of gas works. Wood tar, tar obtained from wood. It is usually obtained by the distillation of the wood of the pine, spruce, or fir, and is used in varnishes, cements, and to render ropes, oakum, etc, impervious to water. Origin: OE. Terre, tarre, AS. Teru, teoru; akin to D. Teer, G. Teer, theer, Icel. Tjara, Sw. Tjara, Dan. Tiaere, and to E. Tree. 63. See Tree. Source: Websters Dictionary (01 Mar 1998) |
| tar acne | An occupational acne-like eruption due to prolonged contact with certain chlorinated compounds (naphthalenes and diphenyls); keratinous plugs (comedones) form in the pilosebaceous orifices, and variously sized small papules (2 to 4 mm) develop. Synonym: chlorine acne, tar acne. (05 Mar 2000) |
| tar camphor | <chemistry> A white crystalline aromatic hydrocarbon, C10H8, analogous to benzene, and obtained by the distillation of certain bituminous materials, such as the heavy oil of coal tar. It is the type and basis of a large number of derivatives among organic compounds. Formerly called also naphthaline. <chemistry> Naphthalene red, a yellow dyestuff obtained from certain nitro derivatives of naphthol. Source: Websters Dictionary (01 Mar 1998) |
| tar keratosis | Warty lesions of the face and hands resulting from repeated, prolonged exposure to tar and pitch; also occurs as keratoacanthoma-like lesions that can become malignant, particularly on the scrotum. (05 Mar 2000) |
| tar syndrome | <syndrome> Tar stands for thrombocytopenia (low blood platelets) and aplasia (absence) of the radius (the long bone on the thumb-side of the forearm), features characterizing this syndrome. There is phocomelia (flipper-limb) with the thumbs always present. The fibula (the smaller bone in the lower leg) is often absent. The risk of bleeding from too few platelets is high in early infancy but lessens with age. The condition is inherited in an autosomal recessive trait with one gene (on a non-sex chromosome) coming from each parent to the tar child. Alternative names include thrombocytopenia-absent radius syndrome, radial aplasia-thrombocytopenia syndrome, and tetraphocomelia-thrombocytopenia syndrome. (12 Dec 1998) |
| tar-water | A cold infusion of tar in water, formerly regarded as a cure-all. (webster, 3d ed) (12 Dec 1998) |
