兔肝内管道研究

On the Vessels and Bile Ducts within Liver of Rabbit Chen Jiaji(Jiangsu Agricultural College,

兔肝内门管鞘系统所包含的门静脉分为左、右２支：左支供应左内叶、左外叶、右内叶及尾状叶，左外叶静脉可分出背、腹侧静脉，左内叶静脉及右内叶静脉各分出内、外侧静脉，尾状叶的静脉也分出左、右侧静脉；右支供应右外叶，分出右外叶静脉和右叶间静脉，右外叶静脉分出背、腹侧静脉。与人肝相似，兔肝内部也分为左、右２叶及左外段（叶）、左内段（叶）、右外段（叶）、右内段（叶）４段，尾状叶的左、右侧部分别隶属于左、右叶。兔肝的外形可分为左外叶、左内叶、右外叶、右内叶、尾状叶及位于胆囊左侧、门静脉左支横部腹侧及方叶支分布区的方叶。肝动脉和胆管的分支与门静脉的相应支伴行，但其分支形式较复杂。兔的肝静脉系统，除肝中静脉外，汇集各叶血液的肝大静脉还有左外叶肝静脉、左内叶肝静脉、右内叶肝静脉、右外叶肝静脉及尾状叶肝静脉，肝小静脉很少。

There are two lobes and four segments in liver of rabbit,i.e.lobus sin-ister, lobus dexter and segmentum sin, lat., segmentum sin,med.,segmentum dext.med.,segmentum dext.lat. ,the two parts of the lobus caudatus belong to the lobussinister and lobus dexter respectively.That is much similar to human’ liver. The portalvein divides into ramus sinister and ramus dexter,The ramus sinister subdivides into v.lobi sin. lat.,v. lobi sin.med.,v,lobi dext.med.and Vv. lobi caudati;the ramusdexter does into v. lobi dext.lat.and v.interlobaris dext.The v. lobi sin, lat. gives offv. dorsalis and v.ventralis;the v.lobi sin。 med.,v. medialis and v. lateralis;the v.lobi dext.med.,the v. medialis and v. lateralis; the v. lobi dext.lat.,v. dorsalis and v. ventralis.The Vv. lobi caudati can be grouped into Vv. sin.and dext.The branchesof hepatic artery and the common hepatic duct accompany the branches of the portalvein.The branching form of the hepatic artery and the common hepatic duct is muchcomplex.The great hepatic veins include v. hepatica lobi sin,lat.,v. hepatica lobi sin. med.,v. hepatica lobi dext. med.,v. hepatica lobi dext. 1at.,v. hepatica lobi caudati and v. hepatica media. Most of the blood of the liver is returned by these veins. The blood of the medial parts of the left medial lobe and right medial lobe is drained by the vena hepatica media. The small hepatic veins are in a very small amount.
