Morphological Characteristics of the Action of Cationic Peptide Warnerin on Regeneration of the Connective Tissue around Implanted Teflon Catheters in Mice under Conditions of Immunosuppression.

Warnerin pretreatment of catheter segments subcutaneously implanted to mice under conditions of immunosuppression led to a significant increase in the number of neutrophils in the surrounding tissues on day 1; the number of fibroblasts tended to decrease by day 3. Immunohistochemical study showed the presence of T and B lymphocytes on day 3, but no positive reactions to vimentin and CD34 were observed during the first 2 days. These changes suggest that warnerin reduced the intensity of regeneration processes in tissues around the implant, which can be used for suppression of fibrosis.

[The nondrug preparation of hypertension patients for treatment of the teeth under central electroanalgesia at a dental polyclinic]. / Nemedikamentoznaia podgotovka bol'nykh gipertonicheskoi bolezn'iu k lecheniiu zubov v usloviiakh stomatologicheskoi polikliniki metodom tsentral'noi élektroanal'gezii.

The authors compare the effects of central electroanalgesia and premedication in hypertensive stomatological patients, administered to prepare the patients to treatment. In contrast to premedication, central electroanalgesia normalized (stabilized) the arterial pressure and pulse rate and did not reduce the rate of reaction to a light stimulus.

[Plasmid preservation in Escherichia coli cells in batch and continuous cultivation]. / Sokhranenie plazmid v kletkakh kishechnoi palochki pri periodicheskom i nepreryvnom kul'tivirovanii.

The growth kinetics of plasmid and nonplasmid strains of 2 isogenic E. coli K12 culture lines has been studied in experiments on batch and continuous cultivation. Under the optimum conditions the growth rate of R+- and R- cells is the same; under the conditions of limited glucose supply the plasmid strains grown slower, as their energy is partly spent on maintaining plasmids in the cell.

[Substrate inhibition and Candida tropicalis growth limitation by phenol in continuous chemostat and pH-stat cultures]. / Substratnoe ingibirovanie i limitirovanie rosta Candida tropicalis fenolom v nepreryvnoi khemostatnoi i pH-statnoi kulture.

The aim of this work was to investigate phenol decomposition by Candida tropicalis 29-10 adapted to phenol as a sole source of carbon and energy, and to elucidate the nature of resistance of continuous cultures decomposing phenol in processes with two types of control, viz. in chemostat and in pH-stat. The results suggest the resistance of the pH-stat regime of microbial cultivation during substrate inhibition. A region of instability in the chemostat cultivation has been determined when the yeast growth was inhibited with phenol.
