Immunoglobulin levels were compared in smoking and non-smoking grain handlers and teachers. Mean IgC and IgM levels were significantly lower, and IgE levels were significantly higher, in the smokers than in the non-smokers. IgA levels were also lower but with the numbers studied not significantly so. IgD levels were unchanged.
对吸烟和不吸烟的谷物处理工人及教师的免疫球蛋白水平进行了比较。吸烟者的平均IgC和IgM水平显著低于不吸烟者，而IgE水平显著高于不吸烟者。IgA水平也较低，但由于研究对象数量的原因，差异不显著。IgD水平没有变化。
