曾经有一病人,不明原因地出现全身蚁行感,瘙痒难耐,四处就医未果,后又渐渐出现视力障碍,肢体麻木,无力等症状,最后被神经科医师检查确诊为“脱髓鞘脑病”。 那么,“脱髓鞘脑病”究竟是怎样的一种病呢? 大家都知道,一般家用的电线,都被外面一层绝缘物质包裹着,以防漏电,让电得以更好地传输。无独与偶,在人的神经纤维外,有一层脂质细胞膜,称为髓鞘,对神经纤维也起着“绝缘”、“保护”作用,以利于神经冲动的快速定向传导。 电线外面的绝缘物质一旦被破坏、电线就要漏电或短
Once there was a patient, unexplained body ants feeling, itching embarrassed, four medical unsuccessful, and then gradually visual impairment, limb numbness, weakness and other symptoms, and finally diagnosed by neurologists diagnosed as “demyelinating encephalopathy.” So, what is a kind of “demyelinating encephalopathy”? As we all know, ordinary household wires are surrounded by a layer of insulating material to prevent leakage and allow electricity to be transmitted better. Coincidentally, in the human nerve fibers, there is a layer of lipid cell membrane, called the myelin, nerve fibers also play an “insulating” and “protective” role in order to facilitate rapid nerve conduction impulse conduction. Once the insulation on the outside of the wire is damaged, the wire will leak or short
