Thiamine pyrophosphatase was demonstrated in the Golgi complex and acid phosphatase in the GERL of acinar cells of submandibular and parotid glands and were previously demonstrated in cells of intercalary ducts. Thiamine pyrophosphatase was also demonstrated in the Golgi complex of cells of striated and excretory ducts and myoepithelial cells. Acid phosphatase was also demonstrated in lysosomes. Alkaline phosphatase was rarely demonstrated light microscopically at luminal surfaces of striated and excretory ducts and electron microscopically in luminal vesicles in cells of striated ducts. The demonstration of the phosphatases in Golgi complexes and GERLs indicates that investigations on these structures in experimental animals are relevant to human salivary glands and supports the opinion that ductal cells as well as acinar cells secrete organic material. The presence of alkaline phosphatase at luminal surfaces of striated and excretory ducts suggests that resorption as well as secretion may occur in them.
硫胺素焦磷酸酶在颌下腺和腮腺腺泡细胞的高尔基体复合物中被证实，酸性磷酸酶在这些腺泡细胞的GERL中被证实，并且之前在闰管细胞中也被证实。硫胺素焦磷酸酶在纹状管、排泄管细胞以及肌上皮细胞的高尔基体复合物中也被证实。酸性磷酸酶在溶酶体中也被证实。碱性磷酸酶在光镜下很少在纹状管和排泄管的管腔表面被证实，在电镜下在纹状管细胞的管腔小泡中被证实。磷酸酶在高尔基体复合物和GERL中的证实表明，在实验动物中对这些结构的研究与人类唾液腺相关，并支持导管细胞以及腺泡细胞分泌有机物质的观点。碱性磷酸酶在纹状管和排泄管管腔表面的存在表明它们可能发生重吸收以及分泌。
