Description/Abstract In the axolotl (Siredon mexicanum, a Urcdela amphlbian) roentgen regression or roentgen reduction is a more or less rapid decrease in size of the treated pontion of the body. The reduction process is distinctly related to the presence in these tissues of a great number of giant cells (macrophages), and their destructive activity. Roentgen regression may be closely related to roentgen stimulation. A paradoxical phenomenon exists in which roentgen rays produce two opposed effects, inhibition and stimulation. Similarly, in mammals roentgen rays produce both an inhibitory and a cancerogenic effect. The cancerogenic effect may appear at the same time as either the inhibitory effect or the secondary stimulating effect. It is possible that difference between the stimulating and cancerogenic effects does not exist and that distinction between them is artificial. (auth)
