| Abstract
|
| [Objective] To research the effect of the collateral circulation re-establish in semi-dark area and electro-acupuncture in the early stage of acute cerebral infarction ischemia in rats with MCAO induced by thread occlusion. The acute cerebral infarction in rat was induced by middle cerebral artery occlusion. [Methods] Using Lectin Histochemistry stain technique the changing of the blood vessel in the penumbra was observed and the effect of electro-acupuncture stimulus on blood vessel count at 1, 3, 6 hours after MCAO was evaluated. [Results] Lectin Histochemistry stain technique was used to reveal the morphological changing of the blood vessel After MCAO. Compared with normal brain, the blood vessel count were reduced in the penumbra (P <0.001). After electro- acupuncture stimulus, blood vessel count was raised in the peri-ischemic zone (P<0.05) at 1,3,6 hours after MCAO. [Conclusion] Electro-acupuncture stimulus can significant increase the blood vessel count in the peri-ischemic zone and promote the establishment of collateral circulation after MCAO. |
