Fig. 4From: Effects of the combined extracts of Herba Epimedii and Fructus Ligustrilucidi on airway remodeling in the asthmatic rats with the treatment of budesonideEffects of budesonide and the herbal extracts on expression of collagen I and collagen I. Expression of the two types of collagen in lung tissue was determined by immunohistochemical staining. (a) IOD of collagen I. (b) Positive area of collagen I. (c) IOD of collagen III. (d) Positive area of collagen III. (e) Representative photomicrographs of collagen I from immunohistochemical-stained lung sections (×400). (f) Representative photomicrographs of collagen III from immunohistochemical-stained lung sections (×400). Mean ± SD, n = 8. ** P < 0.01 compared to normal control group; # P < 0.05 and ## P < 0.01 compared to asthma model group; ▲▲ P < 0.01 compared to budesonide groupBack to article page
