The quantitative regional distribution of neuromedin B-like immunoreactivity in normal postmortem human spinal cord was studied by a specific radioimmunoassay. Neuromedin B-like immunoreactivity was found in highest concentration in the dorsal part of the sacral cord. Chromatographic analyses by gel permeation and reverse-phase high-pressure liquid chromatography revealed two major peaks of neuromedin B-like immunoreactivity and the prevalent molecular form, approx. 90% of the total immunoreactivity, was chromatographically identical to synthetic porcine neuromedin B.
采用特异性放射免疫分析法，研究了正常人体死后脊髓中神经降压素B样免疫反应性物质的定量区域分布。发现神经降压素B样免疫反应性物质在骶髓背侧浓度最高。通过凝胶渗透色谱和反相高效液相色谱分析，发现神经降压素B样免疫反应性物质有两个主要峰，且主要分子形式（约占总免疫反应性的90%）在色谱上与合成猪神经降压素B相同。
