[Dependence of the degree of synergism in the simultaneous action of UV light and hyperthermia on yeast cells on the intensity of the UV light].

In experiments with wild-type diploid yeast cells of Saccharomyces cerevisiae it was shown that the definite temperature interval revealed the synergistic effect under simultaneous action of UV radiation and hyperthermia. The correlation between the degree of synergistic interaction and UV light intensity and irradiation temperature was estimated: the temperature interval synergistically enhancing the UV light effect was shifted towards higher temperatures as the UV light intensity was increasing, the optimal temperature to achieve the most synergistic effect existing for every intensity examined.
