Studies on the Segmental Running of Splenic Tabecular Veins of Korean Cattle by the Vinylite Corrosion Technique

Vinyl 부식법(腐蝕法)에 의(依)한 한우비주정맥(韓牛脾柱靜脈)의 구역적(區域的) 주행(走行)에 관(關)한 연구(硏究)

The studies were conducted to ramify the splenic trabecular veins by injection of vinylite into the splenic veins in twenty five adult Korean cattle. The following results were obtained. 1. Splenic trabecular veins of bovine were collected from 3 chief Rami lienales: Rr. superior, inferior and V. polaris superior of the splenic veins, and the splenic parenchyma was ramified to 5-11 intralienal venous segments by the course of the trabecular veins. 2. Each one of the intralienal venous segments was dealt with 2-4 minute segments therefore, the splenic parenchyma was ramified from 13 minute segments in minimum to 35 minute segments in maximum. 3. The distribution of the veins in the spleen was divided into 7 types by the number of intralienal venous segment, and also was 15 kinds by collecting veins, Rr. superior et inferior and V. polaris superior. 4. The anastomosis was observed in the intralienal venous segments or minute segments. 5. Generally the splenic veins and arteries were like each other, but when observed minutely, they were unlike.
