Knockdown of miR-155 attenuates the pathological damage of skin tissues in CSU rats. (A–B) H&E staining was used to observe the pathological changes of skin tissues in each group of rats and count the number of eosinophils.**P < 0.01, *P < 0.05 vs. normal group; #< 0.05 vs. NC group, ^&&P < 0.05 vs. CSU group, ^∆P < 0.05 vs. in-miR-155 group
