[Plasma renin and erythropoietic activity following a decrease in extracellular volume].

A reduction of the extracellular volume of the peritoneal dialysis in rats induced modifications in plasma renin activity, plasma erythropoietic activity, and in renin activity in the renal cortex. A significant increase in the renin and erythropoietic activity was revealed in the experimental animals. It is assumed that renin and erythropoietin could be regarded as two links of the same broad control system, responsible for optimum tissue oxygen supply.

[Analysis of a subjective assessment of work and morbidity in modern jobs].

An analysis is made of the subjective assessment of work and morbidity in individuals engaged in two groups of up-to-date occupations: a) with considerable, and b) with insignificant nervous strain. The questionnaire study covers 1420 workers. Morbidity analysis is carried out on the basis of data from 1980 temporary disability cards--90 per cent of the workers exposed to a substantial neurosensory stress feel tired at the end of the working day. It is accepted that the cause of fatigue is firstly, the sustained and continuous observation and secondly, the rhythm required. The greater concentration and monotomy are pointed out as the primary cause in group two. The incidence of central nervous system diseases among workshop supervisors and operators of punching machines definitely augments with the length of service. The morbidity rate of gastrointestinal and peripheral nervous system diseases is also rather high.
