Results The clinical and muscle pathological features of this patient were consistent with DM type 1.Sural nerve biopsy showed axonal degeneration with mild demyelination. 结果该例患者的临床表型和肌肉病理改变符合DM1型,腓肠神经主要病理改变为轴索变性,伴有轻度脱髓鞘。
Demyelination and axonal degeneration were confirmed electromicroscopicaly through sural nerve biopsy. 神经活检证实同时有脱髓鞘和轴索变性。
The mechanisms of the secondary damage remote from infarction may be associated with the factors of axonal retrograde degeneration, neurotrophic disturbance, existence of neural growth inhibitory factors, decrease of focal cerebral blood flow, disequilibrium of neurotransmitter adjustment, and inhibition of protein synthesis. 脑梗死后远隔部位继发性损害的机制可能与轴突的退行性改变、神经营养障碍、存在神经生长抑制因子、局部脑血流减少、神经递质调节失衡和蛋白合成抑制等因素有关。
Loss of myelinated fibers due to axonal degeneration was found in sural nerve biopsy. 腓肠神经活检可见有髓神经纤维丢失,轴索变性。
Superficial peroneal nerve biopsy identified myelin degeneration of myelinated nerve fibers, axonal degeneration or disappearance, degeneration of Schwann cell and also involved perineurium. 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。
The EDL contractile force was generally stronger in group ⅲ than in group ⅱ, with a significant difference at 70 and 100 Hz stimulus frequencies from day 4 to 14. Histological sections of nerve revealed less axonal degeneration and earlier regeneration of nerve in group ⅲ. 第3组肌肉收缩力强于第2组,从4~14d在70Hz,100Hz刺激下有显著性差异。组织学切片显示3组呈现较轻的轴突溃变和较早的神经再生。
Objective To investigate the relationship between Ubiquitin and axonal degeneration in the central nervous system ( CNS) of the gracile axonal dystrophy ( GAD) mutant mouse. 目的探索GAD小鼠中枢神经系统的轴索变性和Ubiquitin的相互关系。
The electron microscopy observed marked axonal degeneration of unmyelinated nerve fibers with many leprosy bacillus in Schwann 'cells. 电镜观察发现无髓纤维轴突变性及雪旺细胞里大量麻风杆菌聚集。
The optic nerve in compressed region presented axonal degeneration, glial cell death and blood vessel reduction. In the proximal portion of the compressed nerve were found the astrocyte proliferation and the microglia activation. 视神经慢性受压后损伤区出现轴索变性、胶质细胞死亡和血管减少,损伤区周围出现星形胶质细胞增生和小胶质细胞激活。
After peripheral nerve injury, axonal degeneration and inflammatory reactions gradually lead to neuronal degeneration and necrosis; Schwann cells and fibroblasts act with each other and form connective tissue scar, obstructing axonal regeneration and arrival at remote target organs. 周围神经损伤后,轴突变性、炎症反应等逐渐引起神经元变性、坏死;损伤处的雪旺细胞和成纤维细胞等互相作用,形成结缔组织瘢痕,对轴突再生并到达远端靶器官造成阻碍。
The main parts of the lesions involving the motor neurons of cornu anterius medullae spinalis, and axonal degeneration was the main types of neuropathy. 其病变累及的部位主要在脊髓的前角运动神经元,其神经病变类型主要表现为轴索变性。
Acute SCI generally leads to axonal degeneration, neuronal necrosis, glial scar, etc., and causes limb paralysis and paraplegina. 急性脊髓损伤主要导致轴突变性、神经元坏死、胶质瘢痕生成等,从而造成肢体麻痹、截瘫。
