Abstract
In First Chapter: Thd Materials used for this study consisted of 71 cases, ranging between 14 daysbaby and 79 years of age. The cases in which the diseases of the salivary glands, mouth and pharynx were the direct cause of death were excluded.
I studied these materials annualy and histologically, about glandular cells, intercalated duct, streated duct, excretory duct, interstitial connective tissue, fat cells and Iymph tissue. In Second Chapter:
Clinically and Pathologically, I studied 14 extracted maxillary glands ofsaliolithiasis.
The stastical observation of 98 saliolithiasis, which was reported in Japan from 1941 to 1957, was made.
