| belladonna extract | A powdered extract from the leaves and/or roots of Atropa belladonna; used to formulate various pharmaceutical dosage forms. Contains the alkaloids of belladonna (atropine and scopolamine) and has been used in the treatment of ulcers, diarrhoea, and parkinsonism. (05 Mar 2000) |
|---|---|
| belladonna ophthalmologic | Medications instilled into the eye that result in dilation of the pupil. A common example is homatropine eye drops. (27 Sep 1997) |
| belladonna tincture | A green hydroalcoholic mobile liquid containing the alkaloids atropine and scopolamine and other substances extracted from the leaves of Atropa belladonna, the botanical source for these anticholinergic drugs. The tincture allows for gradual titration of dose by counting drops of the preparation ingested. Formerly widely used in ulcer therapy or the symptomatic treatment of diarrhoea, alone or in combination with antacids and insoluble clays. (05 Mar 2000) |
| Rambourg's periodic acid-chromic methenamine-silver stain | <technique> A stain for glycoproteins, used with an electron microscope, adapted from the Gomori-Jones periodic acid-methenamine-silver stain; it produces silver deposits in mature saccules of the Golgi apparatus, lysosomal vesicles, cell coat, and basement membranes. (05 Mar 2000) |
| Gomori-Jones periodic acid-methenamine-silver stain | <technique> A staining method using methenamine silver, periodic acid, gold chloride, haematoxylin, and eosin to delineate basement membrane, reticulin, collagen, and nuclei; used in renal histopathology. See: Rambourg's periodic acid-chromic methenamine-silver stain. (05 Mar 2000) |
| Gomori's methenamine-silver stain | <technique> Techniques for 1) argentaffin cells: a method using a methenamine-silver solution in combination with gold chloride, sodium thiosulphate, and safranin O; argentaffin granules appear brown-black against a green background; 2) urates: warm sections are treated directly with a hot methenamine-silver solution to produce a blackening of urates; 3) fungi: see Grocott-Gomori methenamine-silver stain; 4) melanin, which reduces silver nitrate. (05 Mar 2000) |
| Grocott-Gomori methenamine-silver stain | <technique> A modification of Gomori's methenamine-silver stain for fungi in which sections are pretreated with chromic acid before addition of the methenamine-silver solution and then counterstained with light green to demonstrate black-brown fungi against a pale green background. (05 Mar 2000) |
| methenamine | <chemical> An antibacterial agent most commonly used in the treatment of urinary tract infections. Its antibacterial action derives from the slow release of formaldehyde by hydrolysis at acidic pH. Pharmacological action: anti-infective agents, urinary. Chemical name: 1,3,5,7-Tetraazatricyclo(3.3.1.13,7)decane (12 Dec 1998) |
| methenamine hippurate | Hexamethylenetetramine hippurate;a urinary antiseptic. (05 Mar 2000) |
| methenamine mandelate | C14H20N4O3;a urinary antiseptic. (05 Mar 2000) |
| methenamine salicylate | Hexamethylenetetramine salicylate;a uric acid solvent and urinary antiseptic. (05 Mar 2000) |
| methenamine-silver | A hexamethylenetetramine-silver complex prepared by adding silver nitrate to methenamine; a white precipitate appears in the solution which dissolves upon shaking and is stable under refrigeration; used in various histological and histochemical staining methods. See: Gomori's methenamine-silver stain. (05 Mar 2000) |
| alkaloids | Organic nitrogenous bases. Many alkaloids of medical importance occur in the animal and vegetable kingdoms, and some have been synthesised. (12 Dec 1998) |
| bisbenzylisoquinoline alkaloids | A group of alkaloids whose base structure is two fused isoquinoline rings e.g., curare alkaloids. (05 Mar 2000) |
| rauwolfia alkaloids | <chemical> Alkaloids from rauwolfia serpentina benth and other species. The prototype is reserpine, which is a depleter of catecholamines and serotonin from the sympathetic postganglionic fibres and brain areas. They have been used in hypertension and psychoses despite their wide range of potentially adverse effects. Pharmacological action: adrenergic uptake inhibitors, antihypertensive agents, antipsychotic agents, sympatholytics. (12 Dec 1998) |
