Some disorders of the brain stem and spinal cord microcirculation were observed in male adult guinea pigs exposed to vertical vibration of frequency 40 Hz and amplitude 1 mm for 3 hours daily during 7, 14, 30 days. These changes after 7 days of vibration were seen as congestion with single small haemorrhages and after 14 days as diffuse spongiosis of the brain stem and spinal cord. After 30 days both congestion with haemorrhages and spongiosis were noted but the first predominated.
在成年雄性豚鼠中,每天暴露于频率为40Hz、振幅为1mm的垂直振动环境下,持续7天、14天、30天,每天3小时。7天后,观察到脑干和脊髓微循环出现一些紊乱,表现为充血伴单个小出血点;14天后,出现脑干和脊髓弥漫性海绵样变。30天后,既有充血伴出血,也有海绵样变,但前者更为明显。
