IMMUNOHISTOCHEMICAL LOCALIZATION OF THE CALCITONIN IN THE SUBMANDIBULAR GLAND OF RAT / 解剖学报

ABSTRACT

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 streptavidin-peroxidase(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.
