[Influence of berotec inhalations on pulmonary gas exchange in patients with bronchial asthma].

Aim: To determine mechanisms inducing changes in lung gas exchange after berotec inhalation in patients with bronchial asthma (BA).

Materials And Methods: A study was made of external respiration function including estimation of lung transfer factor (TLCO sbh.) and its components--transfer coefficient (KCO), membrane diffusion capacity (DM), pulmonary capillary blood volume (Vc)--by the single breath holding method on CO in 14 healthy persons and 39 patients with BA before and after berotec inhalation.

[Pulmonary diffusing capacity in patients with chronic renal failure treated by hemodialysis].

Forty-eight patients with chronic renal insufficiency (CRI) receiving hemodialysis (24 males and 24 females) aged 17-62 underwent bicycle exercise to measure diffuse capacity of the lungs (DCL) before and after the test. DCL components (membraneous and blood volume in pulmonary capillaries, Vc) were defined in 33 out of 48 patients. DCL appeared to reduce significantly (up to 65 +/- 2%) at the expense of Vc fall to 51 +/- 4.
