有人提出门静脉的动脉化可预防或治疗门-腔静脉分流术(PCA)后性脑病。本文研究了胃-冠状静脉的动脉化对大鼠 PCA 后脑病的作用。作者应用30只雄性 Sprague-Dawley 大鼠,先予以装置兴奋中枢及描记皮层活动的电极。于 PCA 手术前、术后第7天及第14天,分别研究网状结构、皮层系统的反应阈。10只大鼠单作 PCA;10只于作 PCA 的同时作胃-冠状静脉的动脉化;10只先作 PCA,于7天后再作胃-冠状静脉的动脉化。手术后第15天,将所有动物杀死,测定肝重/体重比例(R),结果如下。1.门脉系统的动脉化可防止或消除 PCA 引起的网状结构-皮层系统反应阈的降低。所有作 PCA 的大
It has been suggested that arterialization of the portal vein can prevent or treat post-portal-venaventricular shunt (PCA) posterior encephalopathy. This article studies the role of arterialization of the stomach-coronary vein on post-encephalopathy in rats. The authors applied 30 male Sprague-Dawley rats, the first device to be excited central and tracings of cortical electrodes. Before PCA surgery, on the 7th day and the 14th day after surgery, the reaction thresholds of the reticular formation and cortical system were studied respectively. Ten rats were given PCA alone; 10 were given arteriolae of the stomach-coronary vein at the same time as the PCA; 10 were given PCA first, followed by arteriolation of the stomach-coronary vein 7 days later. On the 15th day after the operation, all animals were killed, and the ratio of liver weight / body weight (R) was determined. The results were as follows. 1. Arterialization of the portal system prevents or eliminates PCA-induced reticular formation - a decrease in the response threshold of the cortical system. All for PCA’s big
