Human respiratory tract secretions contain enzyme inhibitors derived from plasma and a low molecular weight, acid-stable protease inhibitor, antileukoprotease. The distribution of antileukoprotease in normal upper respiratory tract mucosa has been studied using an immunohistologic technique. The inhibitor was localized to the serous parts of the submucosal glands of the maxillary sinus and the trachea but was not demonstrable in mucous glands and goblet cells. It is concluded that the antileukoprotease found in respiratory tract secretions is produced locally in the submucosal serous glands.
人类呼吸道分泌物含有源自血浆的酶抑制剂以及一种低分子量、酸稳定的蛋白酶抑制剂——抗白细胞蛋白酶。已使用免疫组织学技术研究了抗白细胞蛋白酶在正常上呼吸道黏膜中的分布。该抑制剂定位于上颌窦和气管黏膜下腺的浆液部分，但在黏液腺和杯状细胞中未检测到。结论是呼吸道分泌物中发现的抗白细胞蛋白酶是在黏膜下浆液腺局部产生的。
