鼻息肉患者鼻息肉组织及鼻分泌物中白细胞介素-5的测定

目的 :探讨鼻息肉患者鼻息肉组织及鼻分泌物中白细胞介素 - 5 (IL- 5 )的含量。方法 :采用双抗体夹心酶联免疫吸附法 (EL ISA)测定鼻分泌物及组织匀浆中 IL- 5含量 ,用 Bradford法测定组织匀浆总蛋白 ,研究对象为 :31例鼻息肉患者 ,8例常年性变应性鼻炎 ,11例慢性鼻窦炎及 6例健康人对照。结果 :1鼻息肉患者鼻息肉组织 IL- 5水平高于慢性鼻窦炎及健康人 (P <0 .0 0 1) ;2鼻息肉患者与常年性变应性鼻炎患者鼻分泌物中 IL- 5水平均明显增高 ,其与慢性鼻窦炎及健康人比较 ,差异有显著意义 (P <0 .0 5 ) ;3在整体水平上 (5 6例 )和鼻息肉组内 (31例 )组织匀浆与鼻分泌物中 IL- 5含量的 Pearson相关系数分别为 0 .70和 0 .6 6。结论 :鼻息肉匀浆组织及鼻分泌物中 IL- 5含量明显升高 ,提示 IL-5与鼻息肉有密切的关系 ,在鼻息肉的发病中起着较为关键的作用。

Study of the concentrations of interleukin\|5 in tissue and secretion of nasal polyps

Objective: To explore the IL\|5 values in the tissue and secretion of nasal polyp. Methods: The concentrations of IL\|5, either in tissue homogenate or in nasal secretion, were measured by ELISA. The values of total protein in tissue homogenate were measured by Bradford colorimetry. In this study, 31 cases with nasal polyp, 8 patients with perennial allergic rhinitis (PAR), 11 cases with chronic sinusitis (CS) and 6 control cases were chosen. Results: ① In tissue homogenate, the IL\|5 concentrations of nasal polyp were higher than that in CS or control group (P＜0.001). ② In nasal secretion, IL\|5 values of both nasal polyp and PAR group were significantly higher than that in CS or control group (P＜0.05). ③ When all cases or only patients with nasal polyp were taken as the subjects, the Pearson correlation coefficient were 0.70, 0.66 respectively. Conclusions: IL\|5 values, both in tissue homogenate and nasal secretion, are significantly higher, which suggested that there were a close relationship between IL\|5 and nasal polyp, and IL\|5 play a key role in the formation of nasal polyp.
