有关稀土元素对实验动物的影响,国内外已有较多研究。这些研究结果证明稀土元素对机体的毒害属低毒物质,但稀土元素对大鼠急性经口给毒所致内脏损伤报导不多。本文通过对混合氯化稀土急性经口给毒所引起的内脏病理组织学观察,阐明氯化稀土对大鼠造成损伤的主要脏器及其病变性质,为稀土毒理研究提供实验依据。 The impact of rare earth elements on experimental animals, there have been more studies at home and abroad. These findings prove that the poison of rare earth elements on the body is a low toxic substance, but the rare earth elements reported on acute visceral injury caused by oral administration in rats. In this paper, by the acute oral administration of mixed rare earth chloride chloride induced visceral histopathological observation to clarify the rare earth chloride damage in rats and its main lesion nature of the experimental evidence for the study of rare earth toxicity.
