| 摘 要： | 用乳胶加颜料血管注射的方法,对32例初生仔猪的腹腔消化器官的静脉属枝进行观察。在32例样本中,有1例(3.13%)肠系膜前静脉出现变异,即该静脉由两枝汇合而成。第一枝只收集近侧的多条空肠静脉和胰十二指肠后静脉。第二枝则汇集其余的静脉枝。结肠中静脉的汇入部位有两种情况:(1)有20例(64.52%)汇入肠系膜前静脉;(2)有11例(35.48%)汇入肠系膜后静脉。胃网膜左静脉,有2例(9.09%)不汇入胃脾静脉,而是向右延续为胃网膜右静脉。

| Abstract: | The veinal tributary of the abdominal digestive organs in 32 newborn piglets were ob- served by means of injecting the latex with the colours.The cranial mesenteric vein,in 1 in- stance(3.31%)out of 32 samples,was formed by the confluence of two tributaries.The first tributary only received proximal jeiunal veins and the caudal pancreticodudenal vein,while the second one received the other tributaries from the distal jejunum,ileum,cecum and asending colon.The convergence of the middle colic vein presents two situations. One situation is that this vein opens into the cranial mesenteric vein,20 instances(64.52%). The other situation is that it empties into the caudal mesenteric vein,11 instances (35.48%).The left gastroepiploic vein,in 2 instances(9.09%)out of 22 samples,doesn't open into the gastrolienal vein,but extends toward the right side of the stomach into the right gastroepiploic vein. |
