Abstract

By neurohistological, morphometric and electron-microscopic methods the effect of vibration of 80 Hz applied at an acceleration of 8 m/sec2 on the nerve cell and conduction components of the kinesthetic analyzer was investigated. After a single exposure to vibration nerve cells of the sensorimotor cortex showed some changes. Exposure to vibration for as long as a week caused reactive changes in every structure of the kinesthetic analyzer investigated. After 1-month exposure the changes were more disseminated and became destructive, after 2-month exposure the process developed at a slower rate, and after 3-month exposure it remained at the same level. However, after 3-month exposure the morphological equivalent of compensatory-adaptive reactions was seen.

摘要

通过神经组织学、形态计量学和电子显微镜方法,研究了在8米/秒²的加速度下施加80赫兹振动对动觉分析仪神经细胞和传导成分的影响。单次暴露于振动后,感觉运动皮层的神经细胞出现了一些变化。暴露于振动长达一周会导致所研究的动觉分析仪的每个结构发生反应性变化。暴露1个月后,变化更为广泛并变得具有破坏性,暴露2个月后,该过程发展速度较慢,暴露3个月后,其保持在同一水平。然而,暴露3个月后出现了代偿性适应反应的形态学对应表现。
