中国黄羽鹌鹑哈德氏腺发育的增龄变化及形态组织学观察

为研究不同周龄中国黄羽鹌鹑哈德氏腺的组织学结构,采集0、1、2、3、4、5、6、10、14、18、22、26、30、34、38周龄健康中国黄羽鹌鹑的哈德氏腺,光学显微镜下观察哈德氏腺的显微组织结构,电镜下观察哈德氏腺的超微结构变化。结果显示,黄羽鹌鹑哈德氏腺位于眼眶内、眼球腹侧和后内侧,出生时就具备完整的形态,在视神经区呈喙状延伸,一端游离,另一端由腺体导管开口于第三眼睑弯窿的内角,腺体呈不规则带状,一端小,一端大,浅粉色,腺体绝对质量、长和宽随周龄逐渐增大。哈德氏腺为复管泡状腺,腺体外有结缔组织被膜,被膜延伸至腺体实质中,将腺体分为多个大小不同的小叶,小叶由腺泡和腺管组成。中国黄羽鹌鹑哈德氏腺在出生后逐渐发育,4周龄时达到成熟,5至38周龄为成熟持续期。

Age-related histomorphological studies on Harderian gland of Chinese yellow quail

To investigate the morphology, growth, histological structure and development of the Harderian gland of the Chinese yellow quail at different ages, the size, absolute weight, and growth index of the Harderian gland, the morphology, growth, histological structure and development of the Harderian gland of the Chinese yellow quail from 0 to 38 weeks were studied. The results showed that the Hadman glands of the Chinese yellow quail had a complete shape at the time of birth and were located in the eyelids, ventral and posteromedial of the eyeballs, and had a rostrum extension in the optic nerve, one end was free and the other end was opened by a gland duct. The inner corners of the third eyelid curve, the glands were irregularly banded, one end was small, one end was large, light pink; absolute mass, length and width gradually increased with age, and Hadrian gland were complex tubular vesicles. The gland had a connective tissue capsule in vitro, and the capsule extended into the gland parenchyma. The gland was divided into multiple leaflets of different sizes, and the lobules were composed of acinar and glandular ducts. The development of the Hadrian gland of the Chinese yellow quail reached maturity at one week after birth, and mature maturity was between 0 and 38 weeks of age.
