Abstract
Background: Allergic asthma is a inflammatory disease defined as a condition of chronic airway inflammation. Asthma can be provoked by various stimuli like allergens inhalation like dust particles, pollen, and pollutants in the air.Objective: This exploration was dedicated to investigate the anti-asthmatic properties of tilianin against the ovalbumin (OVA)-initiated asthma in mice.Methodology The asthma was provoked to the mice via administering 100 ll of aluminum hydroxide containing 20 lg of OVA and treated with the 10 and 20 mg/kg of tilianin, respectively. The levels of Th2 cytokines, OVA-specific IgE, eotaxin, pro-inflammatory mediators, antioxidants, and other markers were inspected by marker specific assay kits. The mRNA expressions of TGF-b1, Smad, iNOS, and COX-2 was assessed using RT-PCR analysis. The lung histology was analyzed microscopically to detect the histological changes.
