| ABSTRACT |
|
The therapeutic effect of mammary breast cancer of rat (Sprague Dawley) was estimated by single and 5 fractionated irradiation of Co60 X-ay. Response rates over 50% were 20, 43, 67, 80% respectively by single dose irradiation of 800, 1,200, 1,600, 2,000rad, and 20, 38, 57, 88% by 5 fractionated irradiation of 1,400, 2,100, 2,800, 3,500rad.
50% tumor control dose (TCD50) were 1,282rad, 2 312rad respectively with single and fractionated irradiation |
