[Animal experiment studies on the use of ozone in irradiated and non-irradiated tumors. I. Intravenous ozone therapy of Crocker's sarcoma 180 and Ehrlich carcinoma in the white mouse]. / Tierexperimentelle Untersuchungen über die Anwendung von Ozon auf unbestrahlte und bestrahlte Tumoren.

The fractionated tangential local X-ray therapy, in cases of sarcoma 180 in white mice with a total dose of 1500 R, effects a shrinking of the tumours as well as a certain number of cures. Intravenous administration of ozone in a total dose of 0.15 times 10(-7)g, 1.5 times 10(-7)g, and 15 times 10(-7)g - by itself or together with irradiation - has as consequence neither an inhibitory effect on the tumour growth, nor an increase in radiation effect that are surpassing the diffusion width of the model and are reproducible in an exact manner. It has been possible to prove an inhibition of the tumour growth in the solid Ehrlich's carcinoma of white mice after a fractionated 2000 R irradiation, but also in these cases, no effect of the ozone application was stated.
