慢性酒精性多发性神经病的临床、病理及电生理特征

报告３５例慢性酒精性多发性神经病患者，全部为男性，年龄３３～７０岁，平均５３．７岁。主要临床症状是四肢疼痛、麻木，袜套－手套式痛温觉减退，震动党消失和肌肉萎缩。运动神经和感觉神经传导速度均有不同程度的减慢。腓浅神经活检见有髓神经纤维髓鞘变性，轴索变性或消失。Ｓｃｈｗａｎｎ细胞变性，也累及神经束膜。此种改变来源于长期饮酒所引起的维生素缺乏所致。

Feature or clinic, pathology and electrophysiology with chronic alcoholic polyneuropathy

patients with chronic alcoholic polyneuropathy (CAPN ) were described. They were all male with age rainging from 33 to 70 years (mean age 53. 7). The cardinal symptoms are. pain and numbness in the extremities, stocking and glove decreased of pain and temperature sense in the legs and arms, the loss of vibration sense and muscule atrophy. The motion nerve conducting velocity (MCV) and sensory nerve conduction velocity (SCV) all are slowed in varying degrees. Superficial peroneal nerve biopsy identified myelin degeneration of myelinated nerve fibers, axonal degeneration or disappearance, degeneration of Schwann cell and also involved perineurium. The change was due to avitaminosis for long-term drinking.
