title: [Methods of silver impregnation in morphological diagnosis of gastric syphilis].
abstract: Comparative assessment of methods of silver impregnation for pathohistological identification of Treponema pallidum in gastric syphilis was performed. Levaditi impregnation is preferable in cases of gastrectomy. Silver impregnation in histological slides is performed for studying endoscopic biopsies in view of their small size as well as for retrospective analysis when paraffin blocks only are available. Steiner's method in modification with the use of microwave stove allows better identification of Treponema pallidum than impregnation by Vartin-Starri. Helicobacter pylori may also be identified by silver impregnation. Association of syphilitic and Helicobacter infections deteriorates inflammatory and destructive lesions in the stomach.
