雏鸵鸟卵巢的形态学研究
Morphological study of the ovary in ostrich chicks
摘要
Abstract
The aim of this study was to reveal the tissue structure characters of the ovary in ostrich chicks. Healthy 90-day-old ostrich chicks were used in this study. This study was based on the anatomy traits, microstructure and ultrastructure of the ovary in ostrich chicks under both histochemical and transmission electron microscopical methods. The results showed that the ovary of ostrich chicks contained primordial follicles, primary follicles and secondary follicles,but no mature follicles. The oocytes in every grade of follicle were large, with an obvious nuclear pore and a heterochromatin mitochondria,centriole,etc. Some unique ultrastructural characteristics were observed in the secondary follicle,such as the cortical granule, which was located in cytoplasm beside the nucleus appeared first in the oocyte. Zona radiata appeared, and formed an obvious vitelline membrane. Additionally, our results showed that there were intraovarian rete, connecting rete, and extraovarian rete in the ovaries of ostrich chicks. Basophilic staining was observed with increasing amount from intraovarian rete to connecting rete,to extraobarian rete. These results indicated that the cellular organs in the cytoplasm of the secondary follicle are much more plentiful than the primary ovarian follicle,especially for the amount of tubiform cristal mitochondrion. Besides, there were rete ovarii in the ovary of the ostrich chicks.关键词
