The duct was reacted histochemically to identify glycoproteins and several enzymic activities. Neutral mucosubstances were detected in the entire cytoplasm of the principal cells, and acid glycoproteins were identified only in a thin apical zone corresponding to the glycocalyx. Lysosomal enzymes were demonstrated as cytoplasmic granules, whereas endogenous peroxidase was diffusely distributed throughout the entire cytoplasm of the epithelial cells. 17 beta- and 3 beta-hydroxysteroid dehydrogenases and prostaglandin-synthetase reactivity were intense in all epithelial cells.
对导管进行组织化学反应以鉴定糖蛋白和几种酶活性。在主细胞的整个细胞质中检测到中性黏液物质，仅在对应于糖萼的薄顶端区域鉴定出酸性糖蛋白。溶酶体酶表现为细胞质颗粒，而内源性过氧化物酶则弥漫分布于上皮细胞的整个细胞质中。所有上皮细胞中17β-和3β-羟基类固醇脱氢酶以及前列腺素合成酶的反应性都很强。
