Alkaline and acid phosphatase activities were studied in the ovary and oviducts of pullets from the age of 2-32 weeks. Adult fowls were similarly studied. Alkaline phosphatase activity was present only in the glandular grooves and crypts of the immature oviducts. Alkaline phosphatase activity appeared at the pits of epithelial evaginations as glandular formation commenced. The young, non-secreting glands also showed the enzyme activity. But in the mature oviduct, alkaline phosphatase activity was confined to only the uterovaginal glands or sperm host glands and the epithelium of the vagina. In the ovary, alkaline phosphatase activity in the theca interna increased as the diameter of the follicles increased. Acid phosphatase activity was not present in the ovary, but in the oviduct, the enzyme activity was present in the uterine (shell gland) glands and in the uterovaginal epithelium and glands (sperm host glands). Alkaline phosphatase activity in the ovarian follicles and in the immature oviduct is thought to be related to histodifferentiation of these structures.
对2至32周龄小母鸡的卵巢和输卵管中的碱性磷酸酶及酸性磷酸酶活性进行了研究。对成年家禽也进行了类似研究。碱性磷酸酶活性仅存在于未成熟输卵管的腺沟和隐窝中。随着腺泡形成开始，碱性磷酸酶活性出现在上皮突起的凹陷处。年轻的、不分泌的腺泡也显示出酶活性。但在成熟输卵管中，碱性磷酸酶活性仅局限于子宫阴道腺或精子储存腺以及阴道上皮。在卵巢中，随着卵泡直径的增加，卵泡内膜中的碱性磷酸酶活性增强。卵巢中不存在酸性磷酸酶活性，但在输卵管中，该酶活性存在于子宫（壳腺）腺以及子宫阴道上皮和腺（精子储存腺）中。卵巢卵泡和未成熟输卵管中的碱性磷酸酶活性被认为与这些结构的组织分化有关。
