Studies on Histological, Cytological and Cyto- chemical Changes in the Submaxillary Glands of the Mouse by Injection

Secretion of saliva has been studies on man and animals from the histological, cytological, and other viewpoints since H e i d en h a i n (1868) and Zimmer m a n n (1898). On the histological and cytological changes of the salivary glands produced by some reagents, Altmann (1894), A r i m a (1918); Takagi (1925) and many others have reported. It is not enough for understanding the function of salivation to observe only the cytological changes. In recent times histochemical and cytochemical investigation have been applied for apprehending the conditions and changes of the organic and inorganic substances and various enzymes in tissues and cells. The author observed the secretion of saliva by the mouse from the histochemical and cytochemical viewpoints . The results obtained will be reported as follows.
