[The influence of coal ashes and soil dust on the activity of two selected hydrolytic enzymes in the liver of laboratory animals]. / Der Einfluss von Kohlenaschen und Bodenstäuben auf die Aktivität zweier ausgewählter hydrolytischer Enzyme in der Leber von Versuchstieren.

The effect of a single intratracheal application of the electroenergetic ashes and the soil dust on the liver cell was studied by means of the histoenzymatic methods for the determination of the activities of chosen hydrolases (AcP, E.C. 3.1.3.2. and ATP, E.C. 3.6.1.). The degree of the histochemical changes in hepatocytes depended on the kind of the applied dust and the trace elements' content in it. The activity's increase of the acid phosphatase and ATP-ase in each experimental group was observed, especially in the preparations collected from the animals were given the electroenergetic ashes.
