稀土元素对心血管功能的影响,国内尚未见报道。国外虽有报道,但定量的整体研究不多。我国某些轻稀土矿区,居民头发中稀土含量较高,并伴有心脏不适、肢体无力的反映。一些稀土生产厂,接触轻稀土粉尘的工人,有心率过缓现象。故有必要探讨摄入过多稀土时,对心血管系统的影响。为此,我们进行了氯化亚铈急性静脉注射和亚急性喂 The impact of rare earth elements on cardiovascular function, has not been reported in China. Although foreign reports, but the overall quantitative research is limited. Some of China’s light rare earth mining area, residents of the high content of rare earth hair, and accompanied by heart discomfort, limb weakness reflected. Some rare earth production plants, workers exposed to light rare earth dust, have heart rate too slow phenomenon. Therefore, it is necessary to explore the impact of excessive intake of rare earth on the cardiovascular system. To this end, we conducted a acute intravenous injection of cerium chloride and subacute feeding
