Abstract: Objective: To investigate the expression and function of S100A8 and S100A9 proteins in chronic submandibular gland sialadenitis. Methods: A rat model of chronic submandibular gland sialadenitis was constructed and human submandibular gland tissues were collected. The histomorphology of chronic sialadenitis and control submandibular glands were observed by HE staining, and the expressions of S100A8 and S100A9 in rat and human chronic submandibular gland tissue were observed by immunohistochemical staining, with aim to explore the mechanism of S100A8 and S100A9 proteins in the progression of chronic sialadenitis. Results: As the ligation time increased, the number of inflammatory cells increased in intralobular interstitium, and the ductal and acinar cells atrophied, accompanied with interstitial fibrosis hyperplasia. The expressions of S100A8 and S100A9 in sialadenitis groups of rats and human were more than those in normal groups. Conclusion: The expression of S100A8 and S100A9 increased with the development of chronic sialadenitis, which could be used as marker proteins for the progression of sialadenitis.
