title: [Morphological picture of the spinal ganglia in guinea pigs exposed to general vibration].
abstract: In the spinal ganglia of guinea pigs exposed to general vibration of 40 Hz frequency and 1 mm amplitude for 3 hrs daily, gradually increasing morphological lesions were found after 7, 14, 30 and 90 days of the experiment. The animals exposed to vibration for up to 30 days exhibited a decrease in the cell nuclei volume, increase in the occurrence of eccentric and marginal cell nuclei and nucleoli, as well as an increase in the number of multiple nucleoli. After 90 days' exposure, such severe lesions as tigrolise, vacuolar degeneration of the cytoplasm, granular disintegration of the myelin sheaths or proliferation of glial cells were found.
