[Physicochemical properties of proteins from wheat grown under high-contrast climatic conditions].

Studies using electrophoresis, gel chromatography, viscometry, and calorimetry revealed an interrelation of several physicochemical properties of proteins of soft wheat grown under conditions of cool and wet weather with rheological characteristics of gluten and dough and bread quality. The ratio of gliadin and albumin-globulin polypeptides in flour with short-tearing gluten was much lower compared to that in flour with normal gluten. Proteins from flour with short-tearing gluten, including the water-soluble and salt-soluble fraction, had a loose spatial structure.

[Physicochemical properties and specific structural features of protein-lipid composites of increased nutritive value].

Fractional and component compositions of protein-lipid composites with increased nutritive value (compared to the protein preparations from which they were produced) were studied based on solubility and electrophoretic behavior. Differences in the fractional compositions of proteins and the amounts of hydrogen, ionic, and hydrophobic bonds were found. It was demonstrated that the water-, salt-, and alkali-soluble fractions of proteins changed during the manufacturing of the composites with soybean and wheat bran flour; the water- and alkali-soluble fractions, with protein concentrate from bran.

[Role of parotitis virus in the development of insulin-dependent diabetes mellitus].

Viral infection is one of the factors provoking the development of insulin-dependent diabetes mellitus (IDDM). Epidemic parotitis more frequently than other infections is connected with IDDM manifestations, but the results of examinations of convalescents after epidemic parotitis and of patients with newly diagnosed IDDM are contradictory. Parotitis viruses are believed to injure pancreatic beta-cells and trigger on the autoimmune process in carriers of certain antigens.

[Immune structure of the pediatric population in relation to the mumps virus and the morbidity of serous meningitis of mumps etiology in Sverdlovsk].

The work presents the results of the longterm study of regularities in the formation of herd immunity to mumps virus in children in Sverdlovsk with due regard to vaccination carried out in this city and morbidity level in serous meningitis of mumps etiology. The inverse correlation between the number of seropositive persons in the total child population and the level of morbidity in the nervous form of mumps has been established. No differences in the size of the immune stratum and the intensity of immunity to mumps virus among boys and girls have been revealed.

[The concentration of antibodies to several exoenzymes of beta-hemolytic streptococci in commercial preparations of gamma globulin].

For the purpose of possible use of commercial preparations of homologous gamma-globulin in the outbreaks of streptococcus affections the authors studied the content of antibodies to some streptococcus antigens, namely to O-streptolysin, streptohyaluronidase and streptokinase. High antibody titres to streptokinase were observed in 62.7, to O-streptolysin--in 35.
