目前已知三种外界因素,(镍、木材粉尘及甲醛)对鼻粘膜有致癌作用。本研究目的在于通过实验确定木材粉尘的致癌作用。过去研究证明木材粉尘经过较长潜伏期以后可以发生鼻粘膜腺癌,特别多发生在筛区,家具制作工高于一般居民500倍。既往研究认为山毛榉子及栎木粉尘具有更大危险性;最近研究发现暴露于软木粉尘中常易发生上皮样或退行性发育的鼻癌。暴露于木 There are three known external factors (nickel, wood dust and formaldehyde) have carcinogenic effects on the nasal mucosa. The purpose of this study is to determine the carcinogenicity of wood dust experimentally. Past studies have shown that nasal mucosal adenocarcinoma can occur after a long incubation period of wood dust, especially in the sieve area, with furniture makers 500 times more likely than average residents. Previous studies suggest that beech and oak dust are more dangerous; recent studies have found that nasopharyngeal carcinoma, which is prone to epithelial or degenerative development when exposed to cork dust. Exposed to wood
