| Abstract |
|
The morphological changes of Sertoli cells of the Korean native pheasant were studied in the active and inactive spermatogenic phases. Twenty-four male of the pheasants were studied in the active (April~June) and inactive(August~March) phase. These data are useful in studying the male genital organs of the Korean native pheasant. Light microscopic morphological changes of the Sertoli cells were studied on paraffin-embedded sections stained with hematoxylin-eosin stain. Ultrastructural changes of Sertoli cells were investigated of ultrathin section using electron microscope. Results are summarized as follows: During the active phase, the average diameter of seminiferous tubule was $245.33{pm}29.93{mu}m$ and was largely decreased by $94.50{pm}14.10{mu}m$, and the thickness of interstitial tissue was comparatively increased during the inactive phase. During the active phase, in the cytoplasmic process of Sertoli cell and lipid droplets appeared disperse. Well-developed smooth Endoplasmic Reticulum and microtuble were observed in the cytoplasmic process. The nuclei of Sertoli cells were adjacent to the basement membrane. The size of nuclei was reduced and nuclei of Sertoli cells were densely packed within the tubule. Few collagen fibers, fibroblast and various sizes of lipid droplets were observed in the interstitial cell of the seminiferous tubule. |
