日本鹌鹑睾丸组织学年龄性变化

本文是研究日本鹌鹁(Coturnix coturnix Japonica)睾丸组织不同日龄的生长发育。精细胞的生长发育可分为六期。初级精母细胞于11天龄出现;36天龄出现精于细胞;46天龄可见已成形的精子。鹌鹑的精子细胞与家畜及鸡的精子细胞在结构与染色特点上有所不同。睾丸间质细胞5天龄前已出现,始终明显地存在于睾丸间质组织中,这与鸡的间质细胞在年龄性变化上存有差异。在21天龄后的曲精细管管腔中,可见数量不等的退化细胞及由数个胞质强嗜酸性的细胞组成的嗜酸小体。小体可见有双核,三核或多核的。

AGE-RELATED HISTOLOGICAL CHANGES IN TESTES OF JAPANESE QUAIL (COTURNIX COTURNIX JAPONICA)

Testicular histological development in Japanese quail of different ages was stud -ied. Six stages in spermatogenesis were distinguished on the basis of microscopic examination. Primary spermatocytes were found in quails ages 11 days. Spermatids occured on day 36. The first mature spermatozoa were present in the seminiferous tubule on day 46. Some difference in structure and stainiing characteristic existed between the spermatids of the quail and those of other farm animal or chicken. The Leydig cells occured in quails before dayopersisted throughout spermatogenesis. This result was at variance with the changes seen in the Leydig cells of the domestic fowl. After 21 days of life, we could find a number of degenerative cells and some eosinophil bodies which consisted of several eosinocytes. Two, Three or even more nuclei were observed in the eosinophil bodies.
