XCH ameliorated viral pneumonia induced by poly (I:C). (a) XCH treatment decreased the W/D ratio in lung tissue. (b) XCH treatment decreased the total protein concentration in BALF. (c) XCH treatment decreased the total cell count in BALF. (d) H&E staining indicated that XCH treatment alleviated the pathological changes in lung (40 and 400×). Black arrows indicated the damage in bronchial epithelial structure and yellow arrows indicated the infiltration of inflammatory cells. Control, model, positive control, XCH low-dose, and XCH high-dose groups (n = 10 per group). ^##: p < 0.01 compared with the control group; ^∗: p < 0.05 compared with the model group; ^∗∗: p < 0.01 compared with the model group.
