Effect of ultrasonic treatment on the organs of experimental animals. III. Enzyme-histochemical examination of the prolonged effect.

The protracted effect of ultrasound treatment on the parenchymatous organs of rats has been studied histochemically at 1 to 10-day intervals. As a result of the altered redox conditions it is the oxidative enzymes in the first place that react to ultrasound treatment and their normalization takes a long time. Exposure decreased the activity of lysosomal enzymes and in the cell membrane the alkaline phosphatase and ATP-ase too. The activity of hydrolases returned to normal parallel with the normalization of the microscopic structure.
