The effect of thermotolerance and of polyhydroxy compounds on the cytotoxicity of bleomycin and cis-platinum was studied in cultured RIF tumor cells. Cell survival in response to drug-heat treatments was compared in cells not previously exposed to hyperthermia and in preheated cells that had
When HeLa S3 cells were subjected to 45 degrees C hyperthermia, DNA lesions were detected by the use of the alkaline unwinding/hydroxylapatite method. The number of lesions formed was not affected when the cells were made thermotolerant by either an acute (15 min 44 degrees C + 5 h 37 degrees C) or
When the potassium content of LM mouse fibroblasts was determined 16 hr after a heat treatment, a correlation was found between the concentration of potassium in the cell population and the level of cellular survival. When the cells were made thermotolerant, the degree of acquired heat resistance
