摘要
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。
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.
