bismuth

 (Bi) [biz´muth]
a chemical element, atomic number 83, atomic weight 208.980. (See Appendix 6.) Its salts have been used for their antacid and mild astringent properties in relief of inflammatory diseases of the stomach and intestines, and as topical protectants in skin and anorectal disorders.
bismuth subsalicylate a bismuth salt of salicylic acid, administered orally in the treatment of diarrhea and gastric distress, including nausea, indigestion, and heartburn.

bis·muth (Bi),

(biz'mŭth),
A metallic element; atomic no. 83, atomic wt. 20.98037. Several of its salts are used in medicine; some contain BiO+, rather than Bi3+, and are called subsalts. The metal is used as an electron microscope stain for nucleic acids.

bismuth

A drug that reacts with the stomach secretions to form a protective coat over the inner lining (mucous membrane) and especially over the floors of peptic ulcers. Bismuth also has a specific effect against the organism Helicobacter pylori which is implicated in the production of peptic ulcers, but has been superceded in this role by more effective drugs such as metronidazole or clarithromycin.

At first glance, the spectral dependencies of the Faraday effect and MCD measured over the range from 330 nm to 800 nm are attributed to the fact that the introduction of bismuth into the iron garnet structure leads to the appearance of a magneto-optical peculiarities between 330 and 500 nm.
