Dynamics of duration of tracheal forced expiratory noises in a group of volunteers was studied before, during and after 520-days confinement. The duration did not change in most volunteers. Two volunteers demonstrated significant changes of tracheal sounds duration and some spirometric parameters.

In previous study it was shown that duration of tracheal forced expiratory noises is promising to reveal negative changes of lung function after dive. The objective is a study of parameters of tracheal forced expiratory noises in changed gas media. The first experiment involved 25 volunteers (22-60 years), performed forced exhalation under normal pressure with air, oxygen-helium and oxygen-krypton mixtures.

Dynamic studies of forced expiration (FE) indices involved 7 normal males aged 21 to 25 participating in a 5-d experiment with dry immersion (DI). FE spirometry was conducted simultaneously with registration of tracheal noise with the help of a microphone. Indices included acoustic duration of tracheal noise (Ta), forced lung capacity (FLC), FE volume per a second (FEV1), peak expiratory rate (PER) and time to reach (T(PER)) before DI, on DI days 1 and 4, and next day after completion.

The effect of cholisorb and its salt (Na and K) forms on the external secretion of the liver was studied. The cholagogic effect of the H-form of cholisorb and its salt forms was demonstrated in dog experiments. The effect of the H-form proved to be stronger.
