Figure 5: The effect of sesame oil on inflammatory cell infiltration in lungs in OVA-treated mice. Sesame oil (0, 0.25, 0.5, or 1 mL/kg, orally) was given to OVA-treated mice, and BALF cell count (a), inflammatory score (b), and tissue histological examination (c) were assessed. Data were mean ± SD ( ). Significant differences of measurement traits were analyzed using one-way ANOVA followed by Students’ t-test. * compared with control group; # compared with OVA-alone group. ND: nondetected. Sham group: mice treated with saline. OVA group: mice treated with OVA only. OVA-SO group: mice treated with sesame oil plus OVA. The arrows indicate neutrophil infiltration (hematoxylin and eosin stain; magnification: ×400).
