[Steroid hormone and trace element content of the blood in patients with disseminated processes of the lungs].

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.

[Biologically active substances of lung tissue in rabbits in an inflammatory bronchopulmonary process].

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.
