四氯乙烯是一种用于清洁剂的有机溶剂，因其环境污染作用受到人们注意。以往的动物实验观察到吸入四氯乙烯对嗅区鼻粘膜的损害比呼吸区严重。该文通过组织病理学技术进一步研究吸入该物质后受损嗅区粘膜上皮的修复过程。选用５周龄雄性小鼠，饲养１周后分为实验组（２０只）和
Tetrachlorethylene is an organic solvent used in detergents, attracting attention due to its environmental impact. Previous animal experiments have observed that inhalation of tetrachlorethylene on the nasal mucosa of the olfactory region is more severe than the respiratory zone. This paper further studies the repair process of mucosal epithelium damaged by inhalation of this substance through histopathology. Five-week-old male mice were selected and divided into experimental group (n = 20) and control group
