title: [Adaptation of the body to the effects of stress increases the resistance of cardiac nuclei to damaging effects of single-chain exogenous DNA].
abstract: The effect of adaptation to stress exposure on the resistance of nuclear DNA to damaging effect of one-chain exogenous DNA was investigated by flow cytometric fluorescence method. It was shown that after the administration of one-chain DNA in concentration of 50 micrograms/ml into the nuclei suspension almost half of nuclear DNA was damaged in control. In adaptation this phenomenon was 5.5 times less pronounced. When the one-chain DNA concentration was increased, this protective effect of adaptation remained. The possible mechanism of the DNA-protective effect of adaptation is under consideration.
