[摘要] 目的：测定变应性鼻炎(allergic rhinitis，AR)患者血中白细胞介素-5(IL-5)、内皮素(ET)及降钙素基因相关肽(CGRP)水平的变化，观察它们在变应性鼻炎中的作用及相互关系，为变应性鼻炎的发病机制、发展及治疗提供依据。方法：选择变应性鼻炎患者36例，慢性鼻-鼻窦炎(chronicrhinosinusitis，CRS)32例，健康对照组30例。分别测定血清IL-5、血浆ET及CGRP水平。结果：IL-5、ET及CGRP含量在变应性鼻炎患者血中较慢性鼻-鼻窦炎患者有明显增高，IL-5、ET及CGRP含量分别为(88.25±33.47)、(77.81±8.26)、(45.32±7.35) ng/L，显著高于慢性鼻-鼻窦炎组[(44.34±16.32)、(72.53±8.34)、(40.07±7.13) ng/L]及健康对照组[(31.24±8.43)、(66.12±7.73)、(35.53±8.02) ng/L]。慢性鼻-鼻窦炎与健康对照组比较亦有明显差异。结论：IL-5、ET及CGRP在变应性鼻炎患者血液中含量较高，它们可能参与了变应性鼻炎的病理生理过程，其变化可能与变应性鼻炎的发生、发展有关。

[Abstract] Objective:To detect expression of interleukin-5, endothelin and calcitonin gene-related peptide in the blood of allergic rhinitis(AR) patients,and observe the relationship between them. Methods: 36 cases with AR,32 cases with CRS and 30 healthy individual served as control group. The levels of interleukin-5 and ET and CGRP were measured and analyzed. Results:IL-5 and ET and CGRP levels[(88.25±33.47)、(77.81±8.26)、(45.32±7.35) ng/L]were significantly higher in AR than in CRS[(44.34±16.32)、(72.53±8.34)、(40.07±7.13) ng/L]. IL-5 and ET and CGRP levels were significantly higher in CRS than control. Conclusion: It is found that concentrations of IL-5，ET and CGRP rised significantly in AR. IL-5, ET and CGRP may be involved in pathogenesis of AR and be related with the development of AR.

变应性鼻炎(allergic rhinitis, AR)在全球发病率呈逐年上升趋势，近年对其病因、发病机制、诊断以及治疗各个环节的研究都得到空前重视。目前已知有多种细胞因子及血管活性物质参与了AR的发生和发展，其中以白细胞介素-5(IL-5)最为重要[1]。内皮素(endothelin ......
