茶尘对制茶工人职业性损害的流行病学调查证明,茶工肺部X线改变及肺功能损害与接尘量、接尘工龄有密切联系,肯定了茶尘的危害。为了解茶尘对工人血液免疫生化方面的影响,我们对我区两个茶厂138名制茶工人血清中IgG、IgA、IgM以及铜蓝蛋白含量进行了测定。同时,为阐明免疫生化改变与临床表现关 Epidemiological investigation on the occupational damage caused by tea dust to tea workers has proved that tea workers’ lung X-ray changes and pulmonary dysfunction are closely linked with the amount of dust taken and the service life of dust, thus affirming the harm of tea dust. To understand the effects of tea dust on the immunobiochemistry of workers’ blood, we measured the contents of IgG, IgA, IgM and ceruloplasmin in serum of 138 tea workers in two tea factories in our district. At the same time, to clarify the immune biochemical changes and clinical manifestations
