title: [Changes in the cytogenetic indices in the bone marrow cells of white rats undergoing mechanical trauma of various degrees of severity].
abstract: The influence of traumatic shock on some cytogenetic indices in bone marrow cells was investigated in white mongrel rats. The traumatic shock was caused by the Noble-Collip method. Comparative analyses of cytogenetic indices during trauma of different intensity show that the most acute changes involve the percentage of aberrant metaphases, and of average number of chromosome breaks per cell. Dynamics of changes of cytogenetic indices after a heavy trauma show that the traumatic shock may exert a cytogenetic effect maintaining for 18 hours. The results obtained and the analysis of literary data enables us to suggest that the speed of development of changes, and restoration of cytogenetic indices under various forms of trauma is quite different and may serve another confirmation of the hypothesis above the possibility of increasing the process of mutagenesis at the expense of the violation of homeostasis.
