It was revealed that the skin humidity is dependent on DPN, particularly, the DPN 2-4 times raises the dryness of the skin on the foot; the risk of callus development is significantly high in case of painless and complicated DPN, accordingly, the possibility of neuropathy ulcer is also high in this group. The high incidence of onychomycosis and Yellow nails syndrome was noted, accordingly in 28.7% and 39.4% of cases; the Melin's shin spots were found in fourth of the patients, mainly in men; a few cases of rubeosis plantarum and bulbosis diabeticorum were revealed; the cases of necrobiosis were not noted.

[Transition of Vibrio cholerae into the non-culturable state under the conditions of low temperature, different mineralization and illumination of artificial culture medium]. / Perekhod cholernykh vibrionov v nekul'tiviruemoe sostoianie v usloviiakh nizkoi temperatury, razlichnoi mineralizatsii i osveshchennosti iskusstvennoi sredy.

The importance of the combined influence of temperature, mineralization and illumination of the medium on the time of the transition of V. cholerae into the uncultivable state has been shown. The reversion of 5- to 60-day variants of uncultivable forms after the elevation of temperature to 20-22 degrees C has been obtained.
