  Objective: We investigated diaphragm contractile and inflammatory properties of mice with OVA sensitization and challenge. Methods: BALB/c mice were sensitized to OVA by intraperitoneal (i.p.) injection at 0 and 7 days, and challenged with aerosolized OVA on 21, 22, and 23 days (O/O group). Budesonide/Formoterol combination was inhaled on days 21, 22, and 23 before OVA challenge on those same days (O/OC group). Control mice were sensitized and challenged with an aerosolized saline (O-group). The diaphragm contractile and inflammatory properties were measured on day 24. NOS activity in the diaphragm muscle was evaluated by NADPH diaphorase staining. IL-4 and IL-13 levels of BALF, as well as lung tissue and diaphragm muscle homogenates were measured by ELISA. Results: Force-frequency (F/f) curves of O/O and O/OC shif.. View More»
