[Determining acid phosphatase (AcP[E.C. 3.1.3.2.]) and adenosine triphosphatase (ATPase [E.C. 3.6.1.3.]) activity in the lungs of rats following a single administration of ashes from industrial high-heat facilities].

There was examined pulmonary tissue of white rats, which had been administered intratrachealy a single dose of the respirable fraction of ashes sample from 6 different power stations elektrohasting plants and hasting plants in Poland (0.2 ml suspension; 50 mg of the examined sample in 0.6 cm3 of NaCl solution). 9 months after the application of the ashes, biopsies of the left lung were taken and there was determined the activity of acid phosphatase (AcP) and adenosinetriphosphatase (ATP-ase) histoenzymatically. There was found sensitivity of these hydrolases and changes of their activity connected with chemical composition of the examined ashes.
