title: [Recovery of yeast cells following the combined action of hyperthermia and ionizing radiation].
abstract: Consecutive action of elevated temperature (50 degrees C) and gamma-irradiation on yeast cells Saccharomyces cerevisiae was studied. It was shown that yeast cells can recover from lethal thermal and radiation lesions after the combined action of the two factors. The efficiency of recovery does not depend upon the sequence of treatments. Heating (50 degrees C) before or after gamma-irradiation increases the radiation response of yeast when plating the cells on a nutrient agar containing 1.5 M KCl. The synergistic effect decreases with yeast cells kept in water at 28 degrees C before plating. The influence of one factor on the effectiveness of recovery from damages induced by the other was estimated.
