[The assessment of the health of industrial enterprise workers and the means for its strengthening]. / Otsenka zdorov'ia rabotnikov promyshlennykh predpriiatii i puti ego ukrepleniia.

The authors provide the results of a sociological interview of the collective of a mixed feed plant. The interview concerned information about health, healthy way of life and routine behavior. Noticeable differences were revealed between the theoretical background of the respondents and daily routine. A rapid method was employed to objectively evaluate the level of the physical health status. A considerable percentage of subjects with low health status were detected. This requires carrying out of the goal-oriented treatment, prophylactic and organizational measures at the plant.

[Effect of calcium on the diastolic phases in healthy persons and in patients with cardiac insufficiency]. / Vliianie kal'tsiia na fazy diastoly u zdorovykh i bol'nykh s serdechnoi nedostatochnost'iu.

Variations in the duration of diastolic phases under acute calcium loading were studied in normal subjects and patients with heart failure, using left ventricular apexcardiography (ACG). Certain changes in diastolic phases were revealed in patients with heart failure as compared to normal subjects, which corresponded to the severity of heart failure. The phase of isometric relaxation as well as those of rapid and slow filling showed the most dynamic variation. The calcium test brought out differences in the effects of calcium on normal and affected myocardium. The established variations may be due to changes in mechanisms of calcium fixation in and the elimination from sarcoplasmatic reticulum.
