摘要
本研究的目的是通过动物实验帮助理解在流行病学调查中见到的某些疾患多发与全身振动的关系。实验用二月龄《哈尔滨》白兔20只,将其随机分为五组(四个实验组和一个对照组)。实验结束后在实验组发现以下不良影响:胃内容物滤液pH值2.77高于对照组,QRS综合波电压0.10~0.24mV也高于对照组,9/16只家兔腰椎X光片上可见椎间隙变窄,腰椎体上缘界限不清,椎体骨质密度改变,3/16只家兔睾丸明显小于对照组,实验组家兔腰椎光镜下病理检查可见骨膜增生。
In order to help understand the adverse effects of WBV found in epidemiolo-gical investigation, animal experiment was carried out 20 male 'Harbin' white rabbits about 2 months of age were experimented, which were allocated into five gronps (tests and control) at random.At the end of experiment adverse effects were found in the test groups. pH value 2.77 in gastric fluid was higher than that of the controls, and QRS waves 0.10-0.24 mV were significantly higher than those in the con trols(P<0.05).Iutervertebral spaces narrowed as showed in the x-ray films of 9/16 rabbits,with blurred upper edges of the lumbar vertebral bodies and osteal changes. 3/16 rabbits' testicles were smaller than the controls. All the test rabbits showed periosteum proliferations of lumbar vertebrae.
