Abstract

Objective:

To investigate the aging changes, the distribution and the content of alpha-amylase, lysozyme in the normal parotid glands.

Methods:

Fifty-one specimens of parotid glands with 4 different age groups were studied by immunohistochemical method. The intensity of staining of alpha-amylase, lysozyme was recorded in different age groups.

Results:

The staining positivity rate of alpha-amylase, lysozyme had striking differences in 4 different age groups and it gradually decreased along with the age increasing.

Conclusions:

There are differences among seous acinus which had similar shape and staining in HE slice. The characters of aging changes of alpha-amylase, lysozyme secreted by acinar and intercalated duct cells are conformity with the results of quantitative studies in histology.
