The immunoglobin pattern was studied in maxillary sinus secretion of 17 patients with maxillary sinusitis. By single radial immunodiffusion, measurable amounts of IgM were found in the secretions of 15 patients, and of IgA and IgG in the secretion of all patients. In purulent sinus secretion, IgA levels were significantly lower than in serous secretion. Of the total content of IgA in sinus secretion, 30% (purulent secretion) and 43% (serous secretion) were calculated to be locally produced, on average. For IgG these figures were 15% (purulent secretion) and 18% (serous secretion), whereas IgM could not be estimated by the method used. It was also concluded that the maxillary sinus is a suitable organ for investigation of local immunity in regard to bacterial infections.
对17例上颌窦炎患者的上颌窦分泌物免疫球蛋白模式进行了研究。通过单向辐射免疫扩散法，在15例患者的分泌物中检测到可测量量的IgM，所有患者的分泌物中均检测到IgA和IgG。在脓性鼻窦分泌物中，IgA水平显著低于浆液性分泌物。鼻窦分泌物中IgA总量的平均值计算得出，脓性分泌物中为30%，浆液性分泌物中为43%为局部产生。IgG的这些数字分别为15%（脓性分泌物）和18%（浆液性分泌物），而IgM无法用所用方法估计。还得出结论，上颌窦是研究细菌感染局部免疫的合适器官。
