title: [Comparative od adaptive response to gamma-radiation and nickel sulfate treatment in human cells].
abstract: Increased viability of human cells (line rhabdomyosarcoma) to challenge doses of NiSO4 (10(-5)-10(-3) M) was formed when cells were preirradiated with low doses of gamma-radiation (10-14 cGy). Observed adaptive response was similar to radioadaptive response in human fibroblasts, pretreated with low doses of gamma-radiation and challenge dose of the same mutagen. Pretreatment with low concentration of NiSO4 induced in human fibroblasts increased resistance of DNA to the treatment with challenge doses of gamma-radiation and stimulated DNA repair synthesis after treatment with NiSO4 and 4-nitroquinoline-1-oxide. These data confirm the existence of cross-adaptation in the experiments with NiSO4.
