[The formation of the normal intestinal microbiocenosis in newborn infants and under antibiotic therapy]. / Formirovanie mikrobiotsenoza kishechnika u novorozhdennykh v norme i pri antibiotikoterapii.

The dynamic study of the microecological state of the intestine in 41 newborns up to the age of 3 months has been made by biochemical and bacteriological investigation methods. The results of the biochemical rapid analysis have been found to be in complete agreement with those of the bacteriological analysis and, besides, to provide essential additional data. The biochemical rapid analysis permits the evaluation of the state resistance to the colonization of the intestine in children, starting from the age of 6 days. The presence of beta-alanine and ninhydrin-positive unidentified Nos. 7, 8a-1, 8d, 9, 10, 11 and 21 is indicative of a greater decrease in the level of the colonization of the digestive tract.

[Pathomorphology of experimental chronic skin ulcers]. / Patomorfologiia eksperimental'noi khromovoi iazvy kozhi

Dynamics of morphological and some histochemical changes was shown on an experimental model of chronic ulcer of the skin (25 guinea-pigs). On the previously epilated and scaridied skin of animals consisting of 4 groups (5 animals in each group) applications of "chromin alkali" with various concentrations of bichromates of potassium and sodium were made; biopsy specimens were taken at 1, 4, 7, 10, 15, 20, 25, and 30 days. The results obtained made it possible to identify 4 stages in the development of chromic ulcer (prenecrotic, necrotic, chromic ulcer, healing), each stage being characterized by its own peculiar features of the clinical course and morphological changes.
