    DERMATOL. Basic Gallate of Bismuth. Subgallate of Bismuth. Dermatol is a trade name for a basic bismuth galiate. It forms a fine, yellow powder, without odor or hygroscopic properties. It contains fifty-five per cent, bismuth oxide. It is practically insoluble. It is employed pure as a powder, united with other desiccants, or exhibited in form of an ointment or collodion (1.5 : 10). Dermatol is protectant, desiccant, and antiseptic. General Surgery.—R. Glaeser {Semaine Med., 1891, No. 27) employs dermatol as a desiccant; while checking serous exudation it stimulates granulations. (J/. B., October, 1891.) Doernberger {Therap. Monatshefte, February, 1892) uses dermatol in the form of an ointment in the treatment in the second degree of Burn. A. Bluhn (idid., December, 1891) treats Carbuncle after incision with advantage by applications of the dry powder. Diseases of the Skin.—Dermatol is recommended by Rosenthal {Monatsh. f. D. u. Syph., i, 1891) as a substitute for iodoform, on account of its stability in air and light, its non-poisonous and its anti- septic qualities, its want of odor, and its drying and healing effect on Wounds. It has not, as yet, been employed extensively in dermatology, but is thought likely to prove useful in affections accompanied by profuse secretion, as Severe Burns, Moist Eczema, Ulcers, etc. The following formulae are suggested : Dermatol, 3j; lanolin, gij; vasehne, gvj. M.—Dermatol, pulv. oxide of zinc, aa gr. 1; vaseline, §j. M.—Dermatol, 3j; pulv. oxide of zinc, amyl, aa ^iiss ; vaseline, §j. Diseases of the Ear, Throat, etc.—Doernberger and Chaniavsky use dermatol pure or united with boric acid in Otorrhoea. Dermatol is recommended by F. Bloebaum {Deutsche Med. Zeit., January i, 1892) as an excellent application to Burns resulting from the use of the galvano- cautery in the pharynx. DEXTRIN. Artificial Gum. Dextrin is produced by the action of acids or diastase on starch. It is freely soluble in both hot and cold water, and forms an exceedingly adhesive, mucilaginous solution. It occurs in commerce in three forms, that of a concentrated solution, as a white powder, and in yellowish-white lumps somewhat resembling gum arable. General Surgery.—Dextrin is one of the substances used in the coating of Lister's protective. The ''protective consists of oiled silk coated with copal varnish ; over the surface of which, when dry, a mixture of dextrin one part, starch two parts, and of cold aqueous solution of car- bolic acid (1-20) sixteen parts, is applied. The object of the treatment is to render the oiled silk impervious to the carbolic acid v.). By this means the carbolic acid is distributed evenly over the surface instead of being disposed in globules, as would otherwise be the case.
