title: Localization of the activity of arylsulphatases A and B in the rat salivary glands.
abstract: A histochemical study has been carried out by light and electron microscopy on the localization of the activity of arylsulphatases A and B in the salivary glands of rat. Results obtained indicate that in the submandibular gland a greater activity is present in the cells of the convoluted granular tubules than in the acina cells, whereas in the sublingual gland the cells of the preterminal tracts appear to be more reactive than those of the terminal tracts. The probable role played by these sulphatases is discussed.
