Abstract

The PAS and protein reaction positive secretion can be found in the parotid and inframandibular gland of rabbit on the 22nd pregnancy day only in the perinuclear zone. On the contrary during the last developmental phase it is localized in the apical zone of the cells and after the birth in all the cytoplasm with the exception of the terminal tracts of the inframandibular gland, which are always PAS negative but positive to the reaction to MPS sulfurated acids. Assumptions are made about the presence of the secretion in the gland cells during the fetal period.
