Figure 2: (A) The effects of co-administration of NIC and OVA on the percentage of eosinophils in the bronchoalveolar lavage fluid. Ten and 1 mg/kg of NIC plus OVA significantly reduced the immigration of eosinophils to the lung tissue compared to the (***P ≤ 0.001). Although both doses of NIC were effective in inflammation suppression, it seems that 10 mg/kg NIC had more suppressive effects on the recruitment of eosinophils. #P ≤ 0.05 and ##P ≤ 0.01 indicate significant differences between groups; (B) indicates digital image of eosinophil. Peripheral smear of the bronchoalveolar lavage fluid stained by the Wright-Giemsa staining method; eosinophils marked by the black arrows. NIC, Nicotine; OVA, ovalbumin.
