[Polarographic analysis of cobalt in biological specimens]. / Poliarograficheskoe opredelenie kobal'ta v biologicheskikh materialakh.

References to different methods of cobalt detection in biologic material are given. Polarographic detection of cobalt in human urine and animal biologic material worked out by authors was used for evaluation of biologic MAC. Biologic material was limed by nitric and sulfuric acids. Sulfuric acid was carefully distilled off the burnt material. Mineralized material was dissolved in 10 ml of 1N hydrochloric acid, filtered and again steamed into moist salts. 2.5 ml of water, 0.5 ml of dimethylglyoxime (0.02 M), 2 ml of Na4P2O7 (0.2 M) and 5 ml of buffer solution (0.1 M NH4Cl and NH4OH) were added to limed mineral, than pH was driven to 9 by 1 = 2 drops of ammonia solution and after blowing through, the specimen was exposed to polarography in alternating current. ++Redox potential of cobalt is 1.18 V. The method can be used for detection of cobalt in urine of workers contacting with the stated metal. Sensitivity of the method is 0.02 Mkg/ml.

[Problems in the further development of postgraduate training in industrial sanitary chemistry for the laboratory physicians of epidemiological health stations]. / Voprosy dal'neishego razvitiia poslediplomnoi podgotovki po promyshlenno-sanitarnoi khimii vrachei-laborantov sanépidstantsii.

The article narrates on the domain of the sanitary inspection medical laboratory workers' supervision in the field of industrial chemistry and their experience in handling different physical and chemical analysis techniques. It is indicated that sanitary inspection medical laboratory personnel requires constant postgraduate training. Proposed is the respective training programme adopted at the Institute for Postgraduate Training of Physicians, Moscow, which includes samples' selection, physical and chemical analysis testing and application in specific conditions, statistical assessment of the results obtained. The programme also includes the hygienic aspects, e. i. current sanitary control, labour hygiene in different gas discharge-related conditions. Practical training is performed in small groups of 2 or 3 persons, thus facilitating adoption of skills in using various analysis techniques. Initial, current and intermediate control, tests and situational analysis are used in the training process.

The paper analyses results after treatment of 30 patients with herpetic keratitis by means of a specific antiherpetic immunoglobulin manufactured at the Sverdlovsk Research Institute of Virus Infections. As compared with traditional treatment, the terms of clinical recovery and the number of bed-days reduced. The preparation can be used in a complex treatment of patients with a herpetic disease.
