The effects of SD treatment on the levels NF-κB p65 and p-STAT3 in the nose of AR mice ((n) = 6, ×400). Immunohistochemistry was used to detect (a) NF-κB p65 and (b) p-STAT3 protein levels. The AOD was used as an index to evaluate protein levels. All error bars represent the mean ± standard deviation. ^##P < 0.01, compared to the control group; ^∗∗P < 0.01, compared to the AR group. SD: Saposhnikovia divaricata, AR: allergic rhinitis, AOD: average optical density, NF-κB: nuclear factor kappa-B, and p-STAT3: phospho-signal transducer and activator of transcription 3.
