Figure 4: The effect of sesame oil on nitric oxide production and iNOS expression 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 lung nitrite level (a) and iNOS expression (b) were determined. 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.
