[The binding of microorganisms isolated from patients with complicated forms of acute cholecystitis with immobilized proteins in the bacterial sorption reaction]. / Sviazyvanie mikroorganizmov, vydelennykh ot bol'nykh s oslozhnennymi formami ostrogo kholetsistita, s immobilizovannymi belkami v reaktsii bakteriosorbtsii.

57 strains of different microbial species, isolated from patients having complicated forms of acute cholecystitis, were studied with the use of the reaction of bacteriosorption on immobilized proteins: fibrinogen, fibronectin, gamma globulin, ovalbumin, etc. The reaction of bacteriosorption was positive with all 4 Staphylococcus aureus strains: they were adsorbed on fibrinogen, fibronectin and gamma globulin. Besides, 4 out of 18 Staphylococcus epidermidis strains were selectively adsorbed on fibronectin and 1 of these strains was adsorbed on ovalbumin, while 2 out of 15 Escherichia coli strains were adsorbed on ovalbumin. S. epidermidis strains studied in this work differed from 15 strains of the same species, isolated from the urine of patients and studied earlier, by their adsorption properties.

[Microflora in patients with complicated forms of acute cholecystitis treated by low-frequency ultrasonics and sulfacrylate glue]. / Dinamika mikroflory u bol'nykh s oslozhnennymi formami ostrogo kholetsistita, lechennykh nizkochastotnym ul'trazvukom i sul'fakrilatnym kleem.

Investigation of microflora in patients with complicated acute cholecystitis treated with low frequency ultrasound in combination with sulfacrylate glue showed that Staphylococcus and Escherichia played the leading role in the complication etiology. Among the nonsporulating organisms bacteroides predominated. The combined use of low frequency ultrasound and sulfacrylate glue in treatment of complicated acute cholecystitis proved to be an efficient procedure providing more rapid sanation of the purulent inflammation foci.

[Characteristics of the protein complexes of clinical strains of mycobacteria]. / Kharakteristika belkovykh kompleksov klinicheskikh shtammov mikobakterii.

The protein composition of Mycobacterium tuberculosis and the molecular weight of proteins contained in these organisms have been determined by the method of electrophoresis in the porosity gradient of polyacrylamide gel. Close similarity between the electrophoregrams of M. tuberculosis clinical and laboratory strains has been revealed. The study of 18 strains of different groups of mycobacteria has shown that M. tuberculosis are essentially different from opportunistic mycobacteria and acid-resistant saprophytes. These data may be important for the identification and taxonomy of mycobacteria.

[Microflora and its antibiotic sensitivity in chronic pharyngitis treated by cryotherapy]. / Issledovanie mikroflory i ee chuvstvitel'nosti k antibiotikam u bol'nykh khronicheskim faringitom, lechennykh kriovozdeistviem

Antibiotic sensitivity of the pharynx mucosa microflora in patients with chronic pharyngitis subjected to cryotherapy was studied. Examination of 36 patients showed that cryotherapy at a temperature of -1950 markedly decreased the number of the grown colonies, their qualitative characteristics being changed. In 10 days both the quantitative and the qualitative characteristics of the flora completely reduced. The cryotherapy did not change the virulence of the flora and its sensitivity to antibiotics.

[Characteristics of the protein spectra of individual representatives of mycobacteria]. / Kharakteristika belkovykh spektrov otdel'nykh predstavitelei mikobakterii

A study of proteinograms of some strains of mycobacteria with the use of the method of electrophoresis in polyacrylamide gel showed that individual strains had characteristic protein spectra which could serve as one of the possible taxonomic characteristics. Analysis of proteinograms of three groups of mycobacteria (tuberculosis, atypical and saprophytes) by electrophoretic mobility of the fractions, with consideration to their homologous character and by the intensity of protein fractions in the mobility zones pointed to heterogeneity of the group of atypical strains and their greater similarity to tuberculosis mycobacteria than to acid-fast saprophytes. Proteinograms of strains H37 Rv and Bov-8 proved to be identical; a marked similarity between the protein spectra of M. avium and M. battey was revealed.
