Figure 1. Huai Qi Huang inhibited infiltration of inflammatory cells into the lung.
The lungs were removed 24 h after the OVA challenge. Sections were stained by Hematoxylin and Eosin (magnification 200×). The experiment was repeated at least six times with similar results and the representative result was shown. n=10 in each group. Arrows indicate the infiltration of inflammatory cells. HE, hematoxylin and eosin.
