摘　　要：目的观察大鼠下颌下腺降钙素(CT)的分布。方法取16只健康的SD大鼠下颌下腺,采用免疫组织化学SP法进行染色。结果在大鼠下颌下腺,可见CT反应阳性物,它们主要分布于浆液性腺泡、混合性腺泡的浆液细胞内,各级导管的上皮细胞也呈CT反应阳性。结论下颌下腺可能具有分泌降钙素的功能,提示下颌下腺可能参与钙磷代谢的生理调节。Objective To observe the distribution of the calcitonin （CT） in the submandibular glands of rat. Methods The submandibular gland tissues of the 16 SD health rats were taken to examine by the immunohistochemical streptavidinperoxidase （SP） technique. Results The results showed that the immunoreactive CT can be observed, they mainly distributed in serous alveoli, serous cells of mixed alveoli, and every duct were also positively immunoreactive to CT. Conclusion The submandibular glands of rat might secrete CT. This suggests that submandibular glands might be related with the regulation of calcium and phosphorus.
