Abstract
Numerous papers related, to the amylase in saliva have hitherto published. However, all of them were investigations on the mixed saliva. The author collected samples of saliva separately from parotid gland, sublingual and submaxillary glands according to the procedures described in his previous paper, and estimated the amylase content according to Wohigemut's method.
The results indicated that the mean value in 20 Japanese cases was 1, 068 D 38° 30'. The amylase content demonstrated no marked change even in the case of a very active secretion of saliva.
Even violent mastication did not affect the amylase level in saliva.
Only in hunger, the amylase level was found raised.
Also in the samples from sublingual and submaxillary glands, starch splitting enzymes, though small in amount, were deteded.
