Abstract

IgG, IgA, IgM, C3 and albumin were measured in 572 samples of gastric juice and the bile fractions A, B and C obtained by a duodenal tube from 143 dermatological patients. The results were correlated to gastric acidity. The findings are consistent with the barrier function of gastric acid secretion, it having been found that, unless hypacidity or anacidity is present, the proteins in the gastric and duodenal fluid show neither high concentrations nor a wide variety. The finding that the fairly high IgA was nearly equal to the amount of IgG in the samples and that the concentration of albumin was much lower (IgG: albumin approximately equal to 2 : 1), seems to indicate that the immunoglobulins were produced by the local immune system.

胃十二指肠液蛋白质含量:浓度及意义。
对143例皮肤病患者经十二指肠管取的572份胃液和胆汁A、B、C部分进行IgG、IgA、IgM、C3和白蛋白的测定。结果与胃酸有关。研究结果与胃酸分泌的屏障功能是一致的,除非存在低酸性或无酸性,否则胃液和十二指肠液中的蛋白质既不高浓度也不多样性。样品中较高的IgA与IgG的含量几乎相等,而白蛋白的浓度则低得多(IgG:白蛋白约为2:1),这似乎表明免疫球蛋白是由局部免疫系统产生的。
