Fig. 4From: Nickel oxide nanoparticles can recruit eosinophils in the lungs of rats by the direct release of intracellular eotaxinMeasurement of total IgE and C5a in serum or BALF after intratracheal instillation of NiO NPs at 200 cm2/rat. Total IgE levels were measured in (a) serum and (b) BALF. Levels of C5a were measured in (c) serum and (d) BALF. Abbreviations: VEHNP, vehicle control for NiO NPs; OVA, ovalbumin-induced allergic airway inflammation; VEHOVA, vehicle control for OVA group. Mean ± SEM (n = 4). Student’s t-test was applied for comparison between OVA group and vehicle control (VEHOVA) with statistical significance indicated by ### p < 0.001Back to article page
