By means of histochemistry and light and electron microscopy one of the links of the postero-ventro-lateral thalamus (PVLT) exposed to the vibration of low frequency (VLF) (95 dB, 8 Hz) was studied. Diffuse mild alterations of PVLT of dystrophic or compensatory nature resembling that in hypoxia were discovered. Disturbances of oxidative metabolism (activation of succinic acid oxidase link of Krebs cycle, use of NADPH potentials and pentose cycle energy in neurons energetics) were alike with that in hypoxia. Shortening of active zone, astrocyte muff presence, overloading with vesicles were found in synapses. Interneuronal contacts disturbance combined with hypoxic alterations appears to be an important mechanism, resulting in negative consequences of the vibration effect.
通过组织化学以及光镜和电镜手段，对暴露于低频振动（VLF）（95分贝，8赫兹）下的丘脑后腹外侧核（PVLT）的一个连接部位进行了研究。发现PVLT存在弥漫性轻度改变，具有营养不良或代偿性质，类似于缺氧时的改变。氧化代谢紊乱（克雷布斯循环中琥珀酸氧化酶环节的激活、神经元能量代谢中NADPH电位和戊糖循环能量的利用）与缺氧时相似。在突触中发现活性区缩短、星形胶质细胞包裹物存在、囊泡过载。神经元间接触紊乱与缺氧改变相结合似乎是一个重要机制，导致振动效应产生负面后果。
