[The prevalence of respiratory organ diseases among those who cleaned up the accident at the Chernobyl Atomic Electric Power Station].

Epidemiological investigation of 206 males aged 30-45 exposed to radiation while working from May 1986 to March 1987 (the period of most likely radioactive dust inhalation damage) in radionuclide-contaminated zone after the Chernobyl accident has been performed. Chronic bronchitis and bronchial asthma occurred in the examinees 4.1 and 7.

[Respiratory tract damage in those who cleaned up the aftermath of the accident at the Chernobyl Atomic Electric Power Station].

The authors have established the fact of acute inhalation damage of the "Chernobyl aerosol" to respiratory organs of the exposed subjects. The complaints correlation to the site of work, time and kind of job shows that respiratory symptoms arose more frequently in those members of emergency teams who arrived at the station in May, August-October 1986, March 1987, stayed for 30-40 days, worked at the site of the damaged reactor, were engaged in decontamination, degasification, drilling, construction and other "dusty" jobs. As a result of inhalation of the Chernobyl dust previously healthy patients developed various respiratory diseases.

[Humoral regulators of erythropoiesis during the body's adaptation to chronic respiratory insufficiency].

It was revealed during examination of 91 patients with chronic nonspecific lung diseases for the blood titers of erythropoietin, erythrocytic chalones, erythrocyte hemolysis products and medium molecules that in the stage I respiratory failure, there were no material changes in the titres of erythrocyte hemolysis products, erythropoietin and medium molecules, whereas the titer of erythrocytic chalones appeared to be high. Stage III of the disease was also marked by no changes in the titer of erythrocyte hemolysis products. However, the titers of erythropoietin and medium molecules rose whereas the titer of erythrocytic chalones was reduced.
