An experimental chronic obstructive sialadenitis model by partial ligation of the submandibular duct characterised by sialography, histology, and transmission electron microscopy.

Abstract:

:Extensive investigation into the mechanism of chronic obstructive sialadenitis (COS) calls for a reliable model that mimics the onset and progression of the disease. Duct obstruction is closely correlated with COS, and partial duct obstruction is usually observed in COS. Partial ligation of ducts or vessels is a valid treatment to mimic pathological processes in certain animal studies. In this study, we developed a novel animal model of COS by incomplete ligation of Wharton's duct and clarified the corresponding morphological alterations in the submandibular gland. Partial ligation of Wharton's duct in Japanese white rabbits resulted in a gradually progressive COS model as demonstrated by sialographic, gross, microscopic, and ultrastructural changes in acinar and ductal degenerations over 8 weeks. The model is a feasible option for investigating the pathogenesis of COS and evaluating the efficacy and safety of novel treatments of COS.
