title: [Histochemical studies of the epithelium of the human ampulla ductus deferentis].
abstract: Human ampullary epithelium contains numerous apical granules, which show a strong P.A.S. reaction, but do not stain with methods for acid mucins. No glycogen is detected. Acid phosphatase and non-specific esterase are localized in granules, scattered within the cytoplasm, while peroxidase activity is not demonstrable. The significance of these results is discussed.
