title: [Effect of ascorbic acid on the frequency of the occurrence of colchicine- and methotrexate-resistant colonies].
abstract: The influence of ascorbic acid (vitamin C) on the frequency of occurrence of colchicine- and methotrexate-resistant colonies of Djungarian hamster DM-15 cells was studied the number of resistant cells was found to increase 2.9-19.8-fold. The genetic effect of using high vitamin C doses is discussed.
