Zusammenfassung: | To observe the expression of the Receptor of Advanced glycation end products (RAGE) in asthmatic rats, and explore the intervention of Roxithromycin.
A total of 18 Specific Pathogen Free-class Brown Norway male rats were randomly divided into control group, asthma model group and Roxithromycin group, with 6 rats in each group. The asthmatic model was sensitized by intraperitoneal injection of Ovalbumin (OVA)+Al(OH)(3), and challenged with OVA. Rats in Roxithromycin group were given Roxithromycin 30 mg/kg 30 minutes before each challenge. Rats in control group and asthma model group were treated with equal volume of saline. The concentrations of RAGE and interleukin (IL)-4 in serum and bronchoalveolar lavage fluid (BALF) were measured by enzyme-linked immunosorbent (ELISA); the pathological changes of lung tissues were observed by HE-staining; the thickness of airway wall and airway smooth muscle were measured by Image-Pro Plus; the relative expression of RAGE in lung tissues were detected by Western blot.
