Abstract

Objectives: In the present study, we evaluate the anti-inflammatory effect of Lonicerae Flos on cigarette-induced lung inflammatory responses in animal model of chronic obstructive pulmonary diseases (COPD). Methods: To inspect the effects of Lonicerae Flos, we evaluated Lonicerae Flos functions in vivo including immune cell profiles in bronchoalveolar lavage (BAL) fluid, cytokine production and tissue morphological changes. Results: Lonicerae Flos significantly inhibited immune cell infiltrations into the BAL fluid (neutrophils, macrophages, lymphocytes). TNF-α, and interleukin-6 (IL-6) were substantially decreased in the BAL fluid of Lonicerae Flos-treated mice compared with cigarette-exposed control mice. In addition, the hypertrophy of goblet cells in the epithelial cells was reduced in both Lonicerae Flos- and roflumilast-treated mice. Conclusions: The results of this study provide evidence that treatment with Lonicerae Flos exerts strong therapeutic effects against cigarette-induced lung inflammation in vivo. Therefore, this herbal medicine may represent a novel therapeutic agent for lung inflammation in general, as well as a specific agent for the treatment of COPD.
