Our study recruited participants with mild to moderate AV. The results showed that level of MDA was decreased in both groups, the decrease being slightly but not significantly higher than that in control group. Although the MDA level was approaching the condition of healthy person, but still higher than that in healthy persons, since at the end of the study the subjects were still suffering from AV. Further study is needed to confirm whether the extension of study periode to 6-8 weeks or the increase of the dosage of EMR would normalize the MDA levels
