Rhy mitigates airway remodeling and oxidative stress in asthmatic mice. a After treatment with Rhy, the lung tissues were subjected to Masson’s trichrome staining and PAS staining. Bar = 200 μm. b Number of PAS-positive cells. c-d Activities of SOD and CAT. N = 6 for each group. The results were presented as mean ± SD. * p < 0.05, ** p < 0.01, *** p < 0.001. Rhy, rhynchophylline; SOD, superoxide dismutase; CAT, catalase; SD, standard deviation
