title: [Growth rate of experimental tumors in x-irradiation].
abstract: Using solid tumors RS-1, Pliss' lymphosarcoma and Guerin's carcinoma it has been noted that growth rates of tumors of different size are reverse proportional to their size: the less a tumor is, the faster its growth rate and a more pronounced therapeutic effect of x-ray irradiation are. A radiation dose fractionation regimen produces a considerable effect on the therapeutic efficacy under the conditions of experimental radiation therapy: with adhering to the general therapeutic scheme the initial irradiation of tumor at a dose of 6 Gy two times every other day proved to be more effective than daily irradiation at a dose of 4 Gy for 3 days.
