Objective:To study the effect of Ailuo Kechuanning on expression of aquaporin5(AQP5) and mucin 5AC(MUC5AC) genes in rats with chronic obstructive pulmonary disease(COPD). Method: Lipopolysaccharide (LPS)smoke was used to COPD rat model;the experimental animals were randomly divided into normal control group
model group.Normal group
model group was given physiological saline(15.52 mL · kg-1 · d-1) by intragastric
Jizhitangjiang group(10 mL · kg-1 · d-1)
Ailuo Kechuanning group (7.75
15.52
31.04 g · kg-1 · d-1)
ig for 14 days. The expression of AQP5 and MUC5AC genes in the trachea
bronchus and lung tissue were detected by in situ hybridization and immunohistochemical techniques. Result: Compared with the normal group
the expression of mRNA and protein of AQP5 were weakened
but the expression of MUC5AC mRNA and protein were enhanced in model group
the expression of AQP5 protein was negatively correlated with MUC5AC protein(P<0.01)in the trachea and lung tissue of model group.Compared Ailuo Kechuanning mediate-dose group with the model group
the expression of AQP5 gene was enhanced. However
the expression of MUC5AC gene was decreased
the expression of AQP5 protein was negatively correlated with MUC5AC protein(P<0.01)in the trachea and lung tissue. Conclusion: The mechanism of Ailuo Kechuanning regulating COPD airway mucus hypersecretion may increase AQP5 gene and inhibit MUC5AC gene expression.
