慢性鼻窦炎手术前后血清和鼻腔分泌物中表皮生长因子水平变化

目的了解慢性鼻窦炎手术前后血清和鼻腔分泌物中表皮生长因子(epidermalgrowth factor,EGF)水平的变化,探讨EGF在鼻内镜术后术腔上皮过程中可能的作用。方法采用放射免疫方法检测慢性鼻窦炎手术患者术前及术后1、2、3、4、6、8周血清和鼻腔分泌物中EGF含量,并分析其变化规律。结果与正常对照比较,慢性鼻窦炎患者血清及鼻腔分泌物中EGF含量均升高,后者更为明显(P<0.0 5);术后第1周鼻腔分泌物中的EGF水平明显降低(P<0.05),第4周后开始升高;血清中EGF水平手术后呈缓慢下降,第6周后者开始上升。结论慢性鼻窦炎手术后血清和鼻腔分泌物中EGF水平存在一定归律的变化,这种变化模式与术后黏膜的转归以及创面修复有关,表明EGF术后鼻腔黏膜修复与上皮化过程中具有重要作用。

Changes of EGF in serum and nasal fluid after endoscopic surgery in patients with chronic sinusitis

Objective To evaluate the changes of epidermal growth factor(EGF) in the serum and nasal fluid after endoscopic surgery in patients with chronic sinusitis,and to explore the possible role of EGF in the postoperative epithelization of sinusal mucosa.Methods Serum and nasal fluid were collected at 1,2,3,4,6,and 8 weeks after functional endoscopic sinus surgery(FESS) and the EGF concentration was measured with radioimmunoassay.Results The EGF levels in the serum and nasal fluid in patients with chronic sinusit...
