Figure 5
Histograms of optical density of immunohistochemistry staining. (a) Optical density of images stained against MDA shows a significant increase in the group treated with 100 mg/kg of ovalbumin and a significant decrease in the posttreated group with 75 mg/kg of butterbur extract. (b) Optical density of images stained against TNF-α shows a significant increase in the group treated with 100 mg/kg of ovalbumin and a significant decrease in the posttreated group with 75 mg/kg of butterbur extract. . aSignificant compared to the control group. bSignificant compared to the ovalbumin group. .
