Microbiology of formation waters from the deep repository of liquid radioactive wastes Severnyi.

The presence, diversity, and geochemical activity of microorganisms in the Severnyi repository of liquid radioactive wastes were studied. Cultivable anaerobic denitrifiers, fermenters, sulfate-reducers, and methanogens were found in water samples from a depth of 162-405 m below sea level. Subsurface microorganisms produced methane from [2-(14)C]acetate and [(14)C]CO(2), formed hydrogen sulfide from Na(2) (35)SO(4), and reduced nitrate to dinitrogen in medium with acetate.

[Ozone therapy of diffuse peritonitis in the early postoperative period].

The study of the use of ozone-containing solutions in 40 experimental animals and in 58 patients with diffuse purulent peritonitis revealed their marked detoxicant effect that manifested with early decrease of ESR, leucocytosis, plasma concentration of bilirubin and medium-size molecules, and microbes. Lethality in the experimental and control group were 5.2 and 16.

[Cytofluorometric study of the glycogen content in DNA-synthesizing and -nonsynthesizing hepatocytes in the regenerating liver].

Using a combined cytochemical method that allows to determine glycogen, DNA and 3H-thymidine label in the same cell, glycogen amounts were measured both in 3H-TdR-marked and non-marked hepatocytes of the regenerating 3H-thymidine. During mitosis, the glycogen amount is reduced if compared with that in cells being in presynthetic phase. It is proposed that the decrease in glycogen content in the regenerating liver may partly depend on energetic expenses of cells that started DNA synthesis and mitotic division.
