我们利用地甲病重患区的粮、菜、水就地饲养大鼠7个月,结果成功地复制了较为理想的人类地甲肿动物模型。在同样条件下,如预先给动物肌肉注射碘油,可达到预防动物发生甲状腺肿的目的。用这种方法所致的甲状腺肿动物垂体前叶细胞的超微结构也发生了明显的变化。但是在患区饲养的实验动物在发生甲状腺肿后,其 We use the acupoints and severely affected areas of food, vegetables, water in situ feeding rats for 7 months, the results successfully replicated a more ideal animal model of human gland. In the same conditions, such as pre-injection of animal muscle lipiodol, can achieve the purpose of prevention of goiter in animals. The ultrastructure of anterior pituitary cells in goiter caused by this method also changed obviously. However, the experimental animals fed in the affected area after the occurrence of goiter
