[Frequency of chromosome aberrations induced by a single exposure to stress in rats selected for excitability of the nervous system].
The effect of short-term emotional and algesic stress on chromosomal aberration rate in bone marrow cells was studied in four lines of rats selected for excitability of the nervous system. The exposure induced an increase in chromosomal aberration rate only in highly excitable animals; the effect was classified as a low mutagenic. Possible mechanisms of the effect of stress factors on the chromosomal apparatus of cells are discussed.
