[Characteristic of iatrogenic odontogenic sinusitis].

Objective: The aim of the study was to study the structure of odontogenic sinusitis and identify iatrogenic etiological factors.

Material And Methods: A retrospective analysis of the case histories of patients operated from 2015 to 2019 with a diagnosis of «Sinusitis» in the Clinical City Emergency Hospital in Tashkent, Republic of Uzbekistan in the department of emergency maxillofacial surgery was carried out. The total number of patients was 333 people: 105 (31.

[Evaluation of a system of multimicrotests for biochemical identification of enterobacteria (MMT E2) in a controlled epidemiological trial. 2].

Commercial system of multimicrotests for biochemical identification of enterobacteria MMT E2 and routine tube tests were compared in a controlled epidemiologic experiment with 205 enterobacterial strains. The system has been developed at the Allergen Research and Production Amalgamation. System MMT E2 fairly well met the requirements to diagnostic preparations of this kind; its results were compatible and well reproducible.

[Assessment of a multimicrotest system for biochemical identification of enterobacteria (MMT E1) in a controlled epidemiological experiment. I].

Comparative evaluation of a system of multimicrotests for biochemical identification of enterobacteria (MMT E1) developed at the ALLERGEN Research and Production Amalgamation and of tube tests for the same purpose in a controlled epidemiologic experiment has shown that the suggested system meets the requirements to such diagnostic preparations by all the major qualitative parameters (compatibility and reproducibility of the test results). Practical use of MMT E1 system will simplify and facilitate the process of enterobacteria identification.

[The characteristics of a Russian-made kit for the serological identification of streptococci groups A, B and C].

The first Soviet kits for the serological identification of streptococci, groups A, B, and C, on the basis of the coagglutination test were developed. Each kit was intended for 35-40 determinations. The optimum concentration of streptococci during their identification by means of the reagents making up the kit was about 1.
