The aim of our study was to investigate the acute effect of quercetin on experimental allergic asthma after single-dose oral administration.
Airway hyperresponsiveness is one of the main features of allergic help with asthma quercetin. None of quercetin experimental studies help with asthma quercetin the acute effect of this flavonol help with asthma quercetin the reactivity of airways both, in vivo and in vitro conditions. Our experiment was realized 21 days after the sensitization of guinea pigs with ovalbumin suspension. Changes in the reactivity of airways were studied using quercetin whole help with asthma quercetin plethysmography in order to compare changes of the specific airway conductance between groups with and without quercetin treatment.
Also changes in the reactivity of the tracheal smooth muscle dipped into the organ bath with Krebs-Henseleit solution were measured as the reaction on cumulative doses of the bronchoconstrictor mediators histamine and acetylcholine. Quercetin was added help with asthma quercetin the solution 30 minutes before the chemical mediators.
The amplitude of tracheal smooth muscle precontracted with histamine or acetylcholine was used as a tracheal smooth muscle reactivity parameter in vitro. Quercetin proved in laboratory help with asthma quercetin help with asthma ability to reduce hyperreactivity of airways link one of the main attribute of allergic asthma Fig.
