本文报道144例接触煤、金属、木尘工人鼻粘膜纤毛传送速度。与非接尘工人比较,其结果接尘工人明显低于非接尘工人(P<0.01)。按医学统计方法将鼻粘膜传送速度进行分级,求得不同种类粉尘作用下纤毛传送速度分布,并用多因素线性回归分析得出其速度y(因变量)与接尘工龄(x_1)、粉尘种类(x_2)和粉尘浓度(x_3)密切相关,其回归方程式为y=8.784090-0.0355(x_1)-0.3856(x_2)+0.0353(x_3),RR=0.2394,P<0.05。本法对判断鼻粘膜损害提供科学依据,亦可作为防治措施效果的评价。
This article reports 144 cases of exposure to coal, metal, wood dust workers nasal mucociliary delivery speed. Compared with non-exposed workers, the results of workers exposed to dust was significantly lower than non-exposed workers (P <0.01). The nasal mucosal delivery rate was graded according to medical statistics, and the distribution of ciliary transmission velocity under different types of dust was obtained. The relationship between the speed of y (dependent variable) and the service life of dust (x_1), the type of dust x_2) +0.0353 (x_3), RR = 0.2394, P <0.05. The regression equation is y = 8.784090-0.0355 (x_1) -0.3856 (x_2) +0.0353 (x_3). This law provides a scientific basis for judging the damage of nasal mucosa, and can also be used as an evaluation of the effect of prevention and treatment measures.
