髓鞘(Myelin Sheath)是包裹在神经细胞轴突外面的一层膜,即髓鞘由髓鞘细胞和细胞膜组成,是神经膜细胞的质膜沿着轴索的轴心旋缠绕形成的多层脂双层结构,髓鞘上有郎飞氏结,可使神经冲动跳跃传递。髓鞘染色在病理诊断中有一定意义,髓鞘的病理变化分为早期、中期和晚期。在早期着色较深;病变中期阶段的髓鞘变性形成脂滴,可用脂质染色加以显示,后期彻底溃变并被吞噬细胞清除,故不再有髓鞘的阳性结果。 很多疾病都可以引起髓鞘的变化,Weil 髓鞘染色可以显示病理情况下髓鞘是否完整、变性、坏死程度及修复情况,对神经组织的病理诊断和研究均有意义,例如神经纤维受损时,髓鞘可出现膨胀、曲折成球形、断裂或脱鞘完全消失等改变。 W774549
