Effect of denatonium benzoate on airway inflammation and remodeling in asthmatic mice / 重庆医学

ABSTRACT

Objective To evaluate the effect of denatonium benzoaten on α-smooth muscle actin (α-SMA),subepithelial collagen and airway inflammation in asthmu mice.Methods Forty-five BALB/c mice were divided into 3 groups,normal control group (A group),asthma model group (B group),asthma model+ denatonium benzoaten group(C group);α-SMA detected by using immunohistochemistry,lung sections were stained with Masson to detect subepithelial collagen,HE stain method was used to observe the airway inflammation the images were analyzed with semi-quantitative computer.Results The deposition of α-SMA、subepithelial collagen and inflammation degree in C group was significantly reduced compared with B group,the difference were statistically significant(P＜0.05).Conclusion Denatonium benzoaten can improve airway remodeling in asthmatic mice.
