[Steroid hormone and trace element content of the blood in patients with disseminated processes of the lungs]. / Soderzhanie steroidnykh gormonov i mikroélementov v krovi bol'nykh s disseminirovannymi protsessami v legkikh.

Blood testosterone, estradiol, hydrocortisone, iron, zinc, and copper levels in males and female patients with lung sarcoidosis, idiopathic fibrosing alveolitis and histiocytosis X were studied. The female patients were in the menopause. A significant decrease in the levels of testosterone and zinc and an increase in the levels of estradiol and copper were revealed in the patients with alveolitis and histiocytosis X. In the patients with lung sarcoidosis a significant decrease in the content of zinc and an increase in the contents of estradiol and copper were stated. There was a relationship between the magnitude of the changes in hormone and trace element levels and the respiratory failure severity.

[Biologically active substances of lung tissue in rabbits in an inflammatory bronchopulmonary process]. / Biologicheski aktivnye veshchestva legochnoi tkani pri vospalitel'nom bronkholegochnom protsesse u krolikov.

The paper is concerned with metabolic reconstitution in a pathologically changed lung tissue in rabbits with acute and chronic bronchopulmonary inflammation. Acute bronchopulmonary inflammation is associated with a drastic increase of the adrenaline, noradrenaline, acetylcholine, histamine and serotonin content in the abnormal lung tissue. The concentration of these substances in the blood outflowing from the lungs is also increased. The intensity of changes in the content of the biologically active substances correlated with the pattern of the developing pathological process. In lingering and chronic bronchopulmonary inflammation, the changes in the content of the biologically active substances were of undulatory character which was consequent on repeated exacerbations.
