Abstract:
This paper reports the histological observation on PAS-positive granular cells in epididymal epithelium from rat, bull, swine and ram. Caput, corpus and cauda of epididymis from these animals (10～14 for each species) were taken, routine fixed and embeded, 6 ?m section, PAS stained and observed under light microscope. There is a kind of PAS positive granular cell existed in epithelium of all segments of epididymis from all these animals. These PAS positive granules are proved to be neutral polysaccharide and an apocrine secretion pattern is suggested. The so-called clear cell in HE stained slides might be PAS-positive granular cell which has already discharged its contents. Besides, this kind of cells are occasionally located in the vas deferens as well.
