摘要
本文对产蛋期金丝雀(Serinuscanaria)输卵管内的贮精腺体进行了组织学和组织化学观察。结果表明,贮精腺体分布于子宫-阴道交接处阴道一侧长度为0.21±0.07cm区域(以下简称UV区域)内的固有膜中。该腺体为管状腺,少数具有分枝,由单层柱状上皮细胞构成。腺细胞顶部无纤毛,细胞核排列整齐,位于细胞的基部。贮精腺体呈PAS阳性,糖原及酸性粘多糖的含量极微或未能检出。脂类含量较为丰富。酸性磷酸酶活性很高,不含碱性磷酸酶。在组织学及组织化学特征上,UV区域与毗邻的子宫及阴道区域存在明显差异,贮精腺体细胞与UV区域粘膜上皮细胞之间的差异也较为显著。
The distribution, histology and histochemistry of sperm-storage glands of canary bird (Serinus canaria) were examined. The results showed that the sperm storage glands were restricted to a small area about 0.2 cm wide at the region of uterovaginal junction of the oviduct. The tubular glands were composed of a single layer of nonciliated columnar cells with basal nuclei arranging rather regularly. Histochemical studies showed that the gland cells exhibited positive PAS reactions and contained very small amount of glycogen and acid mucopolysaccharides. The lipid material was rather abundant in the gland cells. The gland cells showed strong AcP activity but no AlP activity. Differences in histology and histochmistry were found between the area of utero-vaginal junction and its adjacent regions, and there also existed the differences between the gland cells and the mucosal epithelium.
