棉尘症组的ＩｇＧ、ＩｇＡ、ＩｇＭ、ＩｇＥ、总补体、Ｃ３值各指标在高粉尘浓度时较低尘浓度时有增加趋势，而Ｔｃ则相反．经统计学处理有明显差异（Ｐ＜０．０５）．高工龄组的ＩｇＧ、ＩｇＡ、ＩｇＭ、ＩｇＥ值较低工龄组高，Ｔｃ呈明显规律性降低．作者认为．棉生症的发病不仅有体液免疫因素参与，且细胞免疫功能低下也与发病有一定关系。
Cotton dust disease group IgG, IgA, IgM, IgE, total complement, C3 value of the indicators of high dust concentration at lower dust concentrations have an increasing trend, while Tc is the opposite. Significantly different by statistical analysis (P <0.05). High-age group of IgG, IgA, IgM, IgE lower working age group, Tc was significantly decreased regularly. the author thinks. The incidence of cotton disease not only humoral immune factors involved, and cellular immune function is also related to the incidence of disease.
