In vivo and in vitro anti‑allergic and anti‑inflammatory effects of Dryopteris crassirhizoma through the modulation of the NF‑ĸB signaling pathway in an ovalbumin‑induced allergic asthma mouse model. Mol Med Rep. 2020 Nov;22(5):3597-3606 Authors: Piao CH, Bui TT, Fan YJ, Nguyen TV, Shin DU, Song CH, Lee SY, Shin HS, Kim HT, Chai OH Abstract Dryopteris crassirhizoma (DC) has a wide range of pharmacological effects, including antibacterial, anti‑influenza virus, anti‑tumor, anti‑reverse transcriptase and antioxidant effects. However, the inhibitory effect of DC on allergic inflammatory response remains unclear; therefore, the current study used an experimental ovalbumin (OVA)‑induced allergic asthma mouse model and phorbol myristate acetate (PMA)‑ and A23187‑stimulated HMC‑1 cells to reveal the effects of DC in regulating airway inflammation and its possible mechanism. Allergic asthma was initiated in BALB/c mice via exposure to OVA emulsified in aluminum, on days 1 and 14. Thereafter, the mice were treated with DC or dexamethasone (Dex) orally, before being challenged, from days 15 to 26. Subsequently, the mice were challenged with OVA on days 27, 28 and 29. The results of histological analysis indicated that the administration of DC decreased the number of inflammatory cells in the bronchoalveolar lavage fluid (BALF) and suppressed eosinophilic infiltration, mucus production and collagen depositio...
