[Experimental study of histamine-liberating properties of eremomycin].

Eremomycin, a new glycopeptide antibiotic showed the same as ristomycin, polymyxins B and M and kanamycin histamine liberating properties. Liberation of endogenic histamine induced destructive lesions on the mucosa of the gastrointestinal tract. The most pronounced lesions were observed after intraperitoneal administration of the antibiotic. When eremomycin was administered intravenously or subcutaneously the affection of the gastrointestinal tract epithelium was less pronounced. After subplantar administration of the antibiotics pad edema in albino rats was observed. The most pronounced edema was after the use of ristomycin and the polymyxins. After the use of eremomycin and kanamycin it was at the average 2 times less pronounced. Preliminary administration of dimedrol decreased intensity of the pad edema induced by the antibiotics.
