实验性变态反应性神经炎系给实验动物注射周围神经髓磷脂混以Freund完全佐剂所引起的。其临床特点为伴有共济失调的急性运动性麻痹。组织学显示周围神经系统有脱髓鞘现象和单核细胞浸润的局部病灶。非瘤型(结核样型或界线类)麻风病人由于浅感觉方面的选择性受累,可以发生急性感觉丧失,这类病人身上麻风杆菌的数量极少。瘤型麻风尽管有大量的细菌,可是感觉丧失出现得晚,发生于细菌已经变少的时候。这就提出了一个可能 Experimental allergic neuritis was induced in experimental animals by injection of peripheral nerve myelin mixed with Freund’s complete adjuvant. Its clinical features are acute motor paralysis associated with ataxia. Histology showed localized demyelination and mononuclear cell infiltration in the peripheral nervous system. Leprosy (tuberculous or dendritic) leprosy patients suffer from a loss of acute sensation due to their selective sensibility in lightness, and the number of leprosy in such patients is extremely small. Although there is a large amount of bacteria in the leprous leprous form, the loss of sensation occurs later and occurs when the bacteria have become less abundant. This raises a possibility
