摘　　要：This study compares the changes of DNA repair in brain tissue dominated by the middle cerebral artery after electroacupuncture at the acupoints of Renzhong （DU 26）, Neiguan （PC 6）, Quchi （LI 11） and Zusanli （ST 36） in rats. In the apurinic/apyrimidinic endonuclease DNA basic group reparative excision experiments, the apurinic/apyrimidinic endonuclease activity of brain tissue increased slightly after electroacupuncture in rats. In the DNA polymerase β （Pol β）experiments, the Pol β ac-tivity of brain tissue increased after electroacupuncture, especially at DU 26 and PC 6. In the DNA ligase experiments, the expression of DNA ligase 1 in brain tissue increased significantly after electroacupuncture. These findings demonstrate increased activity of apurinic/apyrimidinic en-donuclease, Pol β and DNA ligase 1 after electroacupuncture at DU 26 and PC 6. Also, DNA repair in brain tissue supplied by the middle cerebral artery is promoted after electroacupuncture at DU 26 and PC 6, which are more effective than the LI 11 and ST 36 acupoints .This study compares the changes of DNA repair in brain tissue dominated by the middle cerebral artery after electroacupuncture at the acupoints of Renzhong （DU 26）, Neiguan （PC 6）, Quchi （LI 11） and Zusanli （ST 36） in rats.
