摘要
本文用血管铸型扫描电镜法观察了成人睾丸的血管构筑。迂曲的睾丸动脉主支,在血管膜内,从睾丸门向睾丸游离缘放射状地分布。睾丸表面的粗大静脉与睾丸动脉主支伴行,并由睾丸外周迂曲地朝向睾丸门汇集。在睾丸小隔内有向心动脉、离心动脉以及向心静脉和离心静脉行走。在睾丸小叶内存在管间血管和管周毛细血管丛,后者由两层毛细血管构成。外层为纤细的毛细血管网,内层为较粗的环状毛细血管。在生精小管间的间质内,某些管周毛细血管的起始部相连结形成间质毛细血管丛。
The vascular architecture of the adult man testis was examined by using the
vascular casting method combined with scanning electron microscopy.The circuitous
main branches of testicular artery ran radially from testicular porta towards testicu-
lar free border in tunica vasculosa.The test(?)cular surface veins were accompanied
by the main branches of testicular artery and they converged from testicular circum-
ference circuitously towards testicular porta.There were centripetal artery and
vein as well as centrifugal artery and vein in the septula testis.The intertubular
blood vessels and the peritubular capillary plexus were contained in the testicular
lobules.The latter was made up of two capillary layers.The outer layer was capil-
lary network interwined in fine capillaries.The inner layer was coarse capillary
circles.The interstitial capillary plexus was situated in interstitial tissue between the
seminiferous tubules and compose of capillaries arising from the origin of some
peritubular capillaries.
