Results showed that after 2 months’combined treatment, of the 30 cases, 12 had marked improvement, 15 had improvement and 3 had not any improvement, with an effective rate of 90%; the activity of SOD and GSH-Px increased considerably while the content of LPO lowered strikingly. There were significant differences between pre-and post-treatment in the activity of SOD and GSH-Px and the content of LPO (P<0. 01). It reveals that this method is capable of improving VD patients’ clinical symptoms and signs such as headache, dizziness, hemi-paralysis or hemianesthesia, forced crying and laughing, etc.and also raising the ability of the body in removing oxygen free radical, and suppressing peroxidization of free radical to reduce its products, thereby alleviating the toxic effect of oxygen free radical on the brain tissues.展开更多
