Figure 7.

Effect of curcumin, curcumin-SLNs, and SLNs on airway hyperresponsiveness to inhaled methacholine in OVA-sensitized and OVA-challenged rats.

Notes: Airway hyperresponsiveness was obtained from rats 24 hours after the last challenge in response to methacholine at increasing doses (10–330 μg/kg). The data are expressed as mean ± SEM (n = 8). ^#Indicates P < 0.05 compared to the OVA + curcumin group; **Indicates P < 0.01 compared with the OVA group.

Abbreviations: OVA, ovalbumin; SLNs, solid lipid nanoparticles.
