Zusammenfassung

An Ratten wurde die Wirkung von intraperitoneal eingebrachter wässeriger Salzlösung und Luft auf den Grad der Gewebszerstörung (gemessen am Zerfall der Mastzellen) nach Ultraschall untersucht. Es ergab sich, daß die Gewebszerstörung am größten bei denjenigen Tieren war, denen Luft injiziert worden war; sie entsprach auch der Größe der Zunahme der Körpertemperatur infolge Ultraschallwirkung. Obwohl wässerige Salzlösung ein gutes Zwischenmedium darstellt, war nach ihrer Injektion die Gewebszerstörung und die Zunahme der Körpertemperatur geringer infolge ihrer kühlenden Wirkung.

Summary

The effects of intraperitoneal salt solution (water) and air on the degree of tissue destruction produced by ultrasonic radiation in the rat mesentery were studied. The degree of tissue destruction was greatest in the group of animals having injected air in the peritoneal cavity, and also corresponded to the increase of body temperature caused by the ultrasound. Salt solution (water), although a good transmitting medium, had a cooling effect; therefore with it the destruction of the tissue and the increase of the body temperature were less.
