羊北萱草根中毒尚未见到国外有人报告。作者研究了14例羊(绵羊11例,山羊3例)的试验性北萱草根中毒。用北萱草根干粉喂给试验动物。于一定时间后这些动物均发生中毒。上述病例均见到临床症状、眼观与镜下变化。临床症状主要包括双目失明、沉郁、饮食废绝和高度衰竭。心、肝、肾、第四胃、小肠和神经系统均有病理变化。视径的变化最重要。退行性病变主要局限在视神经和视网膜。本文讨论了这一中毒病的临床病理变化。

Studies on Toxicosis of Root of Hemerocallis Esculenta Koidy in Sheep: Patholoigcomorphology

There have been no reports on toxicosis of the root of Heerocallis esculenta koidy in sheep abroad up to the present. Experimental toxicosis of the root was carried out on 14 animals (11 sheep and 3 goats) by the authors. The experimental animals were fed with toxic amount of the dried root. All of the experimental animals were killed till the end of 1-2 weeks. The clinical symptoms, gross lesions and microsopic changes were observed in these cases. Clinical symptoms included mainly blindness in two eyes, depression, inappetence and profound weakness. Pathological changes were observed in the heart, liver, kidney, abomasum, small intestine and nervous system, etc. Among them the pathological lesions of optic tract were very prominent. The degenerative changes of the optic tract were mainly located in the optic nerves and retinas. Clinicopathological changes of the toxicosis were discussed in the paper.
