Effects of SHO and GIN on inflammatory cell recruitment in BALF. BALF was obtained from the control, OVA, OVA + SHO and OVA + GIN groups. (A) BALF was stained with H&E (magnification, x400; scale bars, 20 µm), and cells were (B) counted with a hematocytometer. Differential cells were classified as lymphocytes (yellow), neutrophils (gray), macrophages (blue) and eosinophils (red). The distribution of inflammatory cells (white blood cells) is expressed as a percentage (mean ± SD, n=6). ^#P<0.05, ^##P<0.01 vs. control group; ^*P<0.05 vs. OVA group. OVA, ovalbumin; SHO, 6-shogaol; GIN, 6-gingerol.
