| Abstract: | There was analysed, by means of biochemical examinations, the behaviour of hydroxyproline level in the lungs of experimental animals exposed to the action of soil dusts and electroenergetic ashes. 44 female white rats of Wistar strain were used in the experiment. The animals were administered intratracheally 0.2 ml dusts and electroenergetic ashes suspension. After decapitation, prepared material was taken from the left lung. Hydroxyproline determinations were performed according to Prokop's und Undenfried's method modified by Tomaszewski and Hanzlik. 9 months after the administration of the dusts, the contents of hydroxyproline slightly differed from the levels observed in control group. |
