[Permeability of plane bilayer lipid membranes in the presence of sarcoplasmic reticulum vesicles].

Interaction between vesicles of sarcoplasmic reticulum (VSR) and bilayer lipid membranes (BLM) was investigated. VSR were added into the membrane-surrounding solution. For the formation of complex VSR-BLM the surface of BLM was charged positively by adding 10(-6) M acetyltrimethylammonium bromide and the transmembrane electrical potential was applied in the negative direction (the positive direction was chosen from inner section of camera with VSR to outer section).

[Study of the antigenic structure of Salmonella by means of immunoelectrophoresis].

The method of immunoelectrophoretic analysis was applied to the study of the antigenic structure of 180 freshly-isolated and laboratory cultures of salmonellae belonging to 29 serological types. A complicated set of specific and common antigens of bacteria was revealed in direct and cross experiments with the use of homologous and heterogenous antisera; immunophoregrams were drawn for each of the serological type under study. General regularities in immunophoretic, diffuse and serological characteristics of the individual antigens of salmonellae were established.
