| 摘 要： | 应用放射免疫分析方法,测定健康豚鼠下呼吸道及循环血液中神经激肽A(NKA)和神经激肽B(NKB)的含量。结果表明,两种肽的免疫反应存在于气管、支气管、肺组织和血液中,其中NKA的含量明显高于NKB。它们在肺内的含量最高,支气管次之,气管最低。实验结果为探讨NKA和NKB在呼吸道的功能和呼吸系疾病中的作用提供了理论依据。

| Abstract: | The concentrations of neurokinin A (NKA) and neurokinin B (NKB) in ithe lower respiratory tract and circulating blood were measured using radioimmunoassay in 16 guinea-pigs. The results show that NKA and NKB immunoreactivity is distributed in the trachea, bronchus, lung and circulating blood. The concentration of NKA is higher than that of NKB in above places. The concentrations of both peptides are the highest in the lung, higher in bronc(?)a, lovest in trachea in the lower respiratory tract.The results will provide a basis for further exploring the functions of NKA and NKB in respiratory tract and their relationship with some respiratory diseases. |
