Study on Lung Injury Caused by Fine Particulate Matter and Intervention Effect of Rhodiola wallichiana

Figure 5

(a–d) 4-HNE expression levels in each group of rats with immunohistochemical staining (200x): NC group (a), NS group (b), PM group (c), and RW group (d). 4-HNE in the PM group was obviously higher than that in the NC and NS groups. 4-HNE expression of the RW group was lower than that of the PM group, which suggested that 4-HNE expression decreased after administration of Rhodiola wallichiana.
