Currently, the therapeutic strategy against memory deficit induced by alcoholism is not satisfactory and is expensive. Therefore, an effective, low-cost strategy is required. On the basis of the memory-enhancing effect of stimulation of the HT7 acupoint, we aimed to determine whether acupuncture at the HT7 acupoint can reduce alcoholism-induced memory impairment. The possible underlying mechanism was also explored. Alcoholism was induced in male Wistar rats weighing 180?220 g. The alcoholic rats received either acupuncture at HT7 or sham acupuncture for 1 minute bilaterally once daily for 14 days. Their spatial memory was assessed after 1 day, 7 days, and 14 days of treatment. At the end of the study, the malondialdehyde level and the activities of catalase, superoxide dismutase, glutathione peroxidase, and acetylcholinesterase enzymes in the hippocampus were determined using colorimetric assays. The results showed that acupuncture at HT7 significantly decreased the acetylcholinesterase activity and the malondialdehyde level, but increased the activities of catalase, superoxide dismutase, and glutathione peroxidase in the hippocampus. These results suggest that acupuncture at HT7 can effectively reduce the alcoholism-induced memory deficit. However, further studies concerning the detailed relationships between the location of the HT7 acupoint and the changes in the observed parameters are required.
