Effects of alcohol and hyperthermia on normal and leukemic lymphocytes.

By the method of viable lymphocyte counts, ethanol was found (1) to have a cytocidal effect on normal and leukemic lymphocytes; (2) to be more toxic to leukemic than to normal lymphocytes; (3) to be synergistic with hyperthermia, and (4) to decrease the critical temperature of normal lymphocytes from 43 to 41.5 degree C.
