    摘要:

    试验共选用(110±5)日龄健康湛江鸡10只,采用微循环观察仪对胸腺进行活体观察,通过做血管透明标本和组织切片的方法观察微血管总体走向、血管细微结构等.结果表明:胸腺的主要血液供应来自于迷走动脉,该动脉起自颈总动脉干的细小分支,其主干延伸至颈部内脏和颈中段的被皮,沿途再分支进入胸腺.该分支进入胸腺后,在接近腺体的中央部位发散形成血管树,经过实质形成毛细血管网.这些毛细血管垂直朝向胸腺表面,或加入浅表的毛细血管丛,或伴随这些毛细血管丛一段距离后返回髓质,形成毛细血管袢.微动脉分支组成不规则的毛细血管网,汇聚成毛细血管后微静脉加入到皮髓交界处的静脉中,汇入腺体表面的血管,进而在胸腺附近构成静脉树,汇集入胸腺静脉最后注入到颈浅静脉.

    Abstract:

    Ten healthy chickens were selected for the observation of chicken thymus by microcirculation microscope in vivo. Transparent vascular specimens and tissue sections were prepared to observe the overall trend of micro vascular and the fine structure of vascular. The results showed that the blood serving thymus was mainly from vagus artery starting from the small dried branch of common carotid artery and extending to the visceral of the neck and the being skin in middle of neck, then branching into the thymus along the way. The branch divergenced into the vascular tree in the central portion close to the glands, forming capillary network after essence. These capillaries went vertically toward the thymus surface, or they would join the superficial capillaries plexus, or with the capillary bundle a distance to return medulla, they formed the capillary loops. Metarterole was connecting extensive venous plexus composed of irregular meshes, whereas the post capillary venule joined the venues at the cortico-medullary boundary and finally into blood vessels at the surface of the glands, thus forming the thymus vein, which emptied into the external jugular vein.
