The study of IgG, IgM and IgA immunoglobulins in the pleural exsudate and in the serum of 34 patients with pleurisy of various etiologies shows an increase in the level of serum immunoglobulins as compared with the level in the exsudate. The only immunoglobulin fraction showing variations in relation with the etiology of the disease in the IgG fraction, which is increased in inflammatory exsudates, in contrast with those found in pulmonary cancers. Recovery without sequellae of pleurisy supposes the presence (in situ) of an increased amount of IgG. These observations are supported by a good statistical-mathematical correlation (p less than 0,01 and 0,001).
对34例不同病因胸膜炎患者的胸腔积液和血清中的IgG、IgM和IgA免疫球蛋白进行研究，结果显示血清免疫球蛋白水平相较于胸腔积液中的水平有所升高。唯一与疾病病因相关呈现变化的免疫球蛋白组分是IgG组分，在炎症性渗出液中其水平升高，这与在肺癌中发现的情况相反。胸膜炎无后遗症恢复的情况意味着存在（原位）数量增加的IgG。这些观察结果得到了良好的统计数学相关性（p小于0.01和0.001）的支持。
