Abstract

A search for microcalculi was made in 14 cases of chronic submandibular sialadenitis. Microcalculi were found in all cases. They were within serous acinar cells and ductal cells, within lumina, and interstitially. They were stained variably by periodic-acid/Schiff and Alcian Blue at pH 2.5. Ultrastructural analytical examination showed them to consist of crystals containing calcium and phosphorus. The observations support the possibility that microcalculi form in autophagosomes, enter lumina and occasionally become impacted to produce sialolithiasis and sialadenitis.

摘要

对14例慢性颌下腺涎腺炎患者进行了微结石检查。所有病例均发现有微结石。它们存在于浆液性腺泡细胞和导管细胞内、管腔内以及间质中。在pH 2.5条件下，它们对过碘酸/希夫试剂和阿尔辛蓝的染色反应各不相同。超微结构分析检查显示它们由含钙和磷的晶体组成。这些观察结果支持了微结石在自噬体中形成、进入管腔并偶尔发生阻塞从而导致涎石病和涎腺炎的可能性。
