title: [Angioroentgenologic response of rat M-1 sarcoma to low-energy infrared laser irradiation at varying frequency].
abstract: After rats with sarcoma M-1 inoculated in the femur area were exposed to low-energy (0.54 mT1) infra-red laser irradiation, 100Hz, for 10 min, the number of contrast-enhanced vessels of tumor fell sharply as compared with controls. That effect lasted for almost 24 hrs. At 1kHz, the total-sum of diameters of such vessels still increased 24 hrs after the exposure. When at 10kHz, that index decreased, and by day 3 vascular pattern and diameter came back to normal in all experiments.
