The serum concentrations of the myotrophic hormone insulin-like growth factor-I (IGF-I) in 23 patients with amyotrophic lateral sclerosis were not significantly different from those found in the sera of 13 control patients. There was no difference in binding of 125I-IGF-I by serum from patients with amyotrophic lateral sclerosis in comparison with that found in the controls. These results indicate that immunoreactive IGF-I concentrations are normal in patients with amyotrophic lateral sclerosis and that such patients do not have significant antibodies binding their endogenous IGF-I.
23例肌萎缩侧索硬化患者血清中的肌营养激素胰岛素样生长因子-I(IGF-I)浓度与13例对照患者血清中的浓度无显著差异。与对照组相比,肌萎缩侧索硬化患者血清对125I-IGF-I的结合无差异。这些结果表明,肌萎缩侧索硬化患者免疫反应性IGF-I浓度正常,且此类患者不存在结合其内源性IGF-I的显著抗体。
