HE staining of lung pathological changes in septic rats. Stained sections were observed under optical microscope (×100). The lung injury scores were as follows: 0 points: normal kidney; 1 point: minimal damage (<10% lesion area); 2 points: mild damage (10%-30% lesion area); 3 points: moderate damage (30%-75% lesion area); 4 points: severe damage (>75% lesion area). Note. ^#Compared with normal group, p < 0.01. ^∗∗Compared with the model group, p < 0.01. ^∗Compared with the model group, p < 0.05.
