Retained maxillary sinus secretions from 10 consecutive patients suffering from maxillary sinusitis were studied with regard to proteolytic activity and its possible sources. All secretions were proteolytically active. In 3 purulent secretions the proteolytic activity was of the same magnitude as that of a standard with an excess of pancreatic trypsin. The enzymes responsible for the proteolytical activity were found to be mainly of granulocyte origin, neutrophil elastase, unspecific collagenase and chymotrypsin-like cationic protein (CCP).
对连续10例上颌窦炎患者的上颌窦潴留分泌物进行了蛋白水解活性及其可能来源的研究。所有分泌物均具有蛋白水解活性。在3份脓性分泌物中，蛋白水解活性与过量胰蛋白酶标准品的活性相当。发现负责蛋白水解活性的酶主要来源于粒细胞，包括中性粒细胞弹性蛋白酶、非特异性胶原酶和类胰凝乳蛋白酶阳离子蛋白（CCP）。
