[Chronic kidney disease in the context of toxic effects the working chemical factors (literature review)].

The article analyzes the publications devoted to the problem of professional renal lesions caused by chemical factors. Classification, prevalence, peculiarities of the clinical picture, diagnosis of professional renal lesions caused by chemical factors of the production environment are reviewed. The frequency of professional renal lesions remains underestimated due to low manifestation of symptoms and the influence of environmental factors, which require further investigation of this issue.

[Analysis of the Effectiveness of Renoprotection of Low-Protein Diet and Ketoanalogues of Amino Acids In Patients With Chronic Kidney Disease].

Aim: Analysis of the effectiveness of renoprotection in patients with chronic kidney disease (CKD), who is observed by general practitioners for up to 72.1 months, keeping traditional LPD or LPD with prescription of ketoanalogues of amino acids (KA/AK).

Cryogenic distillation facility for isotopic purification of protium and deuterium.

Isotopic purification of the protium and deuterium is an important requirement of many physics experiments. A cryogenic facility for high-efficiency separation of hydrogen isotopes with a cryogenic distillation column as the main element is described. The instrument is portable, so that it can be used at the experimental site.

[Reaction to tuberculin in cows and immune response to tuberculosis pathogen antigens in cattle-breeders].

Reactions to tuberculin in cows from a healthy herd were ascertained to be caused by Mycobacterium tuberculosis as latent tuberculous infection was detected in 10.4% of cattle-breeders, including milkmaids looking after infected cows and having a family contact with patients with open-type tuberculosis. In tuberculin-positive cows, the level of antibodies to M.
