[The influence of biophysical factors on biological oxidation and redox processes. 17. Changes in electron transfer and of oxidative phosphorylation steps in liver mitochondria after ultrasonic treatment (author's transl)].

Ultrasonic treatment in vivo brought about distinct changes in liver mitochondria which developed in two directions as to oxygen consumption and oxidative phosphorylation. An increase of oxygen incorporation occurs with short term as well as with long-term experiences. The ratio P/O which expresses the step of oxidative phosphorylation decreases to 1 in the course of one hour after ultrasonic treatment.

[The influence of biophysical factors on biological oxidation and redox processes. 16. The possibility of influencing flavine coenzymes in liver mitochondria by means of ultrasonic treatment (author's transl)].

The quantity of FAD and FMN in mitochondria isolated from the liver of albino rats was determined before and after application of ultrasonic energy with the intensities 0,2,0,6 and 1,0 w/cm2 in a short-term test, and the intensity 0,2 w/cm2 applied at ten successive days in a long-term test. The total amount of the two coenzymes as well as their percentages were ascertained. The following results derive from our experiments: 1.
