摘要

目的 :探讨塞来昔布抑制慢性支气管炎大鼠气道粘蛋白高分泌的作用。方法 :Wistar大鼠气管内注入 0 .1%脂多糖2 0 0 μl复制模型

采用图象分析、ELISA等方法检测病理学改变、支气管肺泡灌洗液（BALF）中粘蛋白量的变化。结果 :注入脂多糖 3周后出现慢性支气管炎的病理学表现

包括杯状细胞增生、粘膜下腺体增生肥大

分泌细胞内及BALF中粘蛋白量增加 ;塞来昔布可以显著减少每 1mm气管上皮中杯状细胞数目、上皮及腺体细胞粘蛋白面积 %与未分泌指数、BALF中粘蛋白含量。结论 :塞来昔布通过特异性地抑制环氧化酶 2的活性

可以减少慢性支气管炎大鼠气管上皮杯状细胞增生

也可抑制杯状细胞和粘液腺体粘蛋白的合成分泌亢进。

Abstract

Objective: To investigate the inhibition of celecoxib on the hypersecretion of airway mucins in the chronic bronchitis rats. Methods: Rat chronic bronchitis model was established by intratracheal instillation of 0.1% lipopolysaccharide 200μl.With image analysis and ELISA

the changes of pathology and mucins in bronchoalveolar lavage fluid(BALF)were observed. Results: The rats shared many features of chronic bronchitis after instillation

including goblet cells hyperplasia

submucosal glands hyperplasia and hypertrophy

mucins overabundance of secretory cells and BALF.Celecoxib could remarkably decrease the number of goblet cells per 1mm epithelium

mucins area% and pre-secretion index of glands and epithelia

mucins in BALF. Conclusion: Through inhibiting specifically cyclooxygenase 2

celecoxib could decrease goblet cells hyperplasia

inhibit excessive mucin synthesis and secretion in goblet cells and mucus glands of chronic bronchitis rats.
