[A comparative analysis of the intracellular potassium content for the cardiomyocyte in papillary muscle tissue and in a primary heart culture].

This work was aimed to examine potassium contents in heart myocytes. The intracellular concentration of this element was measured with electron probe microanalysis (EPMA). The cardiomyocyte was studied in samples of the papillary muscle tissue and in heart primary culture.

[The determination of the chemiluminescence of stimulated blood leukocytes in assessing the activity of chronic pyelonephritis].

The activity of oxidant metabolism was studied in leukocytes from the whole blood of 23 patients diagnosed to have urolithiasis, chronic pyelonephritis in remission. Leukocyte function was evaluated by registration of luminol-dependent chemiluminescence. Barium sulfate microcrystals served leukocyte stimulator.
