| carbon monoxide-methylene blue oxidoreductase | <enzyme> Molybdenum-containing iron-sulfur flavoprotein from pseudomonas carboxydovorans; forms carbon dioxide Registry number: EC 1.2.3.- Synonym: cm-mb oxidoreductase, carbon monoxide oxidase (26 Jun 1999) |
| methylene blue | <chemical> Methylthionine chloride; dark green crystals or crystalline powder having a bronze-like luster, readily reduced to colourless leukomethylene blue, which in turn is readily oxidised to methylene blue. Used as a bacteriologic stain and as an indicator, and administered orally or intravenously in the treatment of congenital methemoglobinaemia and cyanide poisoning. Pharmacological action: anti-infective agents, urinary, antidotes, dyes. Chemical name: Phenothiazin-5-ium, 3,7-bis(dimethylamino)-, chloride (12 Dec 1998) |
| polychrome methylene blue | An alkaline solution of methylene blue which undergoes progressive oxidative demethylation with aging (ripening) to produce a mixture of methylene blue, azures, and methylene violet; boiling with sodium carbonate or other oxidizing agents accomplishes this result quickly, although it is not as highly regarded.

| eosin-methylene blue agar | Agar composed of peptone, lactose, and sucrose and containing eosin and methylene blue, used to distinguish between lactose-fermenting and non-lactose-fermenting Gram-negative bacteria. Synonym: EMB agar. (05 Mar 2000) |

| Loeffler's methylene blue | A stain for diphtheria organisms that contains methylene blue in dilute ethanol plus a slight amount of potassium hydroxide; dye solution gives best results when aged to a polychrome state. (05 Mar 2000) |
| phenyl | <chemistry> A hydrocarbon radical (C6H5) regarded as the essential residue of benzene, and the basis of an immense number of aromatic derivatives. <chemistry> Phenyl hydrate, a nitrogenous base (C6H5.N2H3) produced artificially as a colourless oil which unites with acids, ketones, etc, to form well-crystallized compounds. Origin: Gr. To bring to light + -yl: cf. F. Phenyle. So called because it is a by-product of illuminating gas. Source: Websters Dictionary (01 Mar 1998) |
| phenyl alcohol | <chemistry> 1. A white or pinkish crystalline substance, C6H5OH, produced by the destructive distillation of many organic bodies, as wood, coal, etc, and obtained from the heavy oil from coal tar. It has a peculiar odour, somewhat resembling creosote, which is a complex mixture of phenol derivatives. It is of the type of alcohols, and is called also phenyl alcohol, but has acid properties, and hence is popularly called carbolic acid, and was formerly called phenic acid. It is a powerful caustic poison, and in dilute solution has been used as an antiseptic. 2. Any one of the series of hydroxyl derivatives of which phenol proper is the type. <chemistry> Glacial phenol, any one of a series of compounds having both phenol and aldehyde properties. Phenol phthalein. See Phthalein. Origin: Gr. To show + -ol: cf. F. Phenol. Source: Websters Dictionary (01 Mar 1998) |
| phenyl aminosalicylate | P-aminosalicylic acid phenyl ester;an antituberculous drug. Phenyl salicylate, the salicylic ester of phenol; the phenylic ester of salicylic acid; an intestinal analgesic and antipyretic; it has been used in the treatment of rheumatism, diarrhoea, and pharyngitis, as an enteric coating for tablets, and in ointments for sunburn prevention. Synonym: salol. (05 Mar 2000) |
| hyoscyamine | <chemical> A chemical with the formula C17H23O3N which is a white powder at room temperature and which melts at 108.5 degrees C. It comes from plants such as henbane and belladona. Hyoscyamine is used medically as the levorotatory isomer of racemic atropine and as an anticholinergic alkaloid. (08 Mar 2000) |
| hyoscyamine (6S)-dioxygenase | <enzyme> A 2-oxoglutarate-dependent dioxygenase that catalyses hydroxylation of l-hyoscyamine to 6beta-hydroxyhyoscyamine in biosynthetic pathway to scopolamine; requires fe2+ Registry number: EC 1.14.11.11 Synonym: hyoscyamine 6beta-hydroxylase, hyoscyamine 6 beta-hydroxylase (26 Jun 1999) |
| hyoscyamine sulfate | <drug> An antispasmodic, hypnotic, and sedative, also used in parkinsonism to relieve tremor, rigidity, and excessive salivation. (05 Mar 2000) |
| dl-hyoscyamine | <drug> A toxic alkaloid extracted from belladonna and other members of thenightshade family, it is typically used to dilate the eye and to stopmuscular spasms. Pharmacologic action: Parasympatholytic. Competitive blockade of acetylcholine at muscarinic receptors. Increases sinus node automaticity and AV conduction. Uses: Treat bradycardia, asystole, and AV block Dose: 0.5 - 1.0 mg for bradycardia every 3 - 5 min to a total dose of 0.04 mg/kg. Doses smaller than 0.5 mg can cause a paradoxical bradycardia due to sympathomimetic effects Typically 3 mg is adequate to completely block vagal effects Atropine is well absorbed via endotracheal route - administer 1-2 mg diluted in 10 mL sterile water or normal saline. Potential complications: 1. Tachyarrhythmias 2. Exacerbation of myocardial ischemia 3. Low dose may cause paradoxical bradycardia 4. Dry mouth, urinary retention, flushed and hot skin 5. Crosses blood-brain barrier which can cause delirium Note: The denervated heart will not respond to atropine. (15 Mar 2000) |
