| digitus quintus | The little or fifth finger. Synonym: digitus minimus, digitus quintus, digitus auricularis, fifth finger. (05 Mar 2000) |
|---|---|
| digitus secundus | The second finger (the thumb being counted as the first). Synonym: digitus secundus, forefinger, index, second finger. (05 Mar 2000) |
| digitus tertius | Third finger. Synonym: digitus medius, digitus tertius, third finger. (05 Mar 2000) |
| digitus valgus | Permanent deviation of one or more fingers to the radial side. Digitus varus, permanent deviation of one or more fingers to the ulnar side. (05 Mar 2000) |
| diglossia | A developmental condition that results in a longitudinal split in the tongue. See: bifid tongue. Origin: G. Di-, two, + glossa, tongue (05 Mar 2000) |
| diglucosyldiacylglycerol synthase | <enzyme> Catalyses formation of major, lamellar-forming diglucosyldiacylglycerol from major, nonlamellar-prone monoglucosyldiacylglycerol; isolated from acholeplasma laidlawii Registry number: EC 2.4.1.- Synonym: diglucosyl diacylglycerol synthase, dglcdag synthase (26 Jun 1999) |
| diglyceride lipase | <enzyme> An enzyme of the hydrolase class that catalyses the reaction of triacylglycerol and water to yield diacylglycerol and a fatty acid anion. The enzyme hydrolyzes triacylglycerols in chylomicrons, very-low-density lipoproteins, low-density lipoproteins, and diacylglycerols. It occurs on capillary endothelial surfaces, especially in mammary, muscle, and adipose tissue. Genetic deficiency of the enzyme causes familial hyperlipoproteinaemia type I. Chemical name: Triacylglycero-protein acylhydrolase Registry number: EC 3.1.1.34 (12 Dec 1998) |
| diglycocoll hydroiodide-iodine | Two moles of diglycocoll hydroiodide combined with two atomic weights of iodine; an antibacterial agent used in tablet form to disinfect drinking water. (05 Mar 2000) |
| dignathus | A malformed foetus with a double mandible. Synonym: augnathus. Origin: G. Di-, two, + gnathos, jaw (05 Mar 2000) |
| digoxigenin | A plant steroid hormone which, when combined with a probe biomolecule, can be used to attract antibodies in certain probe systems. (09 Oct 1997) |
| digoxin | <chemical> A cardiotonic glycoside obtained mainly from digitalis lanata; it consists of three sugars and the aglycone digoxigenin. Digoxin has positive inotropic and negative chronotropic activity. It is used to control ventricular rate in atrial fibrillation and in the management of congestive heart failure with atrial fibrillation. Its use in congestive heart failure and sinus rhythm is less certain. The margin between toxic and therapeutic doses is small. Pharmacological action: anti-arrhythmia agents, cardiotonic agent, enzyme inhibitors. Chemical name: Card-20(22)-enolide, 3-((O-2,6-dideoxy-beta-D-ribo-hexopyranosyl-(1-4)-O-2,6-dideoxy-beta-D-ribo-hexopyranosyl-(1-4)-2,6-dideoxy-beta-D-ribo-hexopyranosyl)oxy)-12,14-dihydroxy-, (3beta,5beta,12beta)- (12 Dec 1998) |
| digoxin toxicity | A result of the over-accumulation of digitalis glycosides in the body. Kidney insufficiency can be a contributing factor. Symptoms include nausea, vomiting, visual changes, blurred vision, anorexia and palpitations. Treatment is emergent as life-threatening cardiac arrhythmias are possible with higher blood levels. (27 Sep 1997) |
| digoxygenin | Small molecule derived from foxgloves, that is used for labelling DNA or RNA probes and subsequent detection by enzymes linked to antidigoxygenin antibodies. Proprietary to Boehringer Mannheim. (18 Nov 1997) |
| digram | A digraph. Origin: Gr. = twice + letter. Source: Websters Dictionary (01 Mar 1998) |
| digraph | Two signs or characters combined to express a single articulated sound; as ea in head, or th in bath. Origin: Gr. = twice + a writing, to write. Source: Websters Dictionary (01 Mar 1998) |
