Effect of NEES on the Occurrence of c-Fos in the Cerebrum of a Rat With Transient Global Ischemia

Ischemia that causes strike induces inflammation of brain cells and apoptosis and as a result. it influences much in the functional part of a man. The needle electrode electrical stimulation (NEES) that combines acupuncture of oriental medicine with electric therapy of western medicine relieves inflammation of cells and has effect on regrowth of nerve tissues. This study was conducted to verify the influence of MEES on the occurrence of c-Fos of cerebrum after applying NEES to the meridian point, Zusanli (ST36) of rats with induced ischemia. Global ischemia was induced by using ligation method on common carotid artery of male Sprague Dawley (SD) rats. The ligation was maintained for 5 minutes and then suture was removed for blood reperfusion. After inducing global ischemia, NEES was done to the left and right meridian points of Joksamri of a rat for 30 minutes after 12 hours, 24 hours, and 48 hours. The findings were as follows. 1. In the result of immunohistochemical method, the number of c-Fos immune response cells significantly decreased(p<.05) in NEES group than the control group (G1) that did not get NEES. 2. In the result of western blotting, the occurrence of c-Fos after 24 hours from the inducement of ischemia significantly decreased (p<.05) in NEES group than the control group (G1) that did not get NEES. Therefore, as the effect of NEES was shown highest after 24 hours from the ischemia, it is suspected that NEES would take important role in early treatment after cerebral stroke.
