Effect of Pseudoephedrine + emodin on pathological changes of lung tissues (×200), expression of AQP‐1, AQP‐5 in LPS‐induced ALI rats. A The chemical structure of Pseudoephedrine and Emodin. B Stained with hematoxylin and eosin. C The lung injury score was determined following a five-point scale from 0 to 4 as follows: 0, l, 2, 3, and 4 represent no damage, mild damage, moderate damage, severe damage, and very severe damage, respectively. Representative histological sections of the lungs were stained with hematoxylin and eosin (H & E staining, magnification ×200). D–F Western blot analysis was performed to detect AQP‐1 and AQP‐5 protein expression. K The dry/wet weight ratio and lung weight/body weight ratio were used to reflect the pulmonary edema. All data are expressed as mean ± S.D. (n = 5). ^##p < 0.01, ^###p < 0.001 vs. control group. *p < 0.05, **p < 0.01, ***p < 0.001 vs. LPS alone group. ⁺p < 0.05, ⁺⁺⁺p < 0.001 vs. combined treatment group (5 + 20 mg/kg)
