[Effect of ultrasound on porphyrin biosynthesis. I. Changes in the levels of proto-, copro- and uroporphyrins after a single exposure to ultrasound].

Abdominal region of white rat males was exposed to ultrasound with the intensity of 0.2, 0.6 and 1.

[Ultrasonic effect on synthesis and excretion of porphyrines].

A ten-fold sequential action of supersound on rats results in disturbances in synthesis of protoporphyrine IX and its excretion respectively; the level of protoporphyrine in erythrocytes and feces is reduced. Redistribution of porphyrines in erythrocytes is detected; the control level of coproporphyrines being retained; a higher initial content of protoporphyrine IX drops due to an increase in a relatively low level of porphyrines.
