Effects of electroacupuncture on the contents of NO, ET and T-AOC in the brain tissues of the cerebral hemorrhage model rats.

In the cerebral hemorrhage model rats established by injection of collagenase and heparin into caudate nucleus, the effects of electroacupuncture (EA) on the contents of nitric oxide (NO) and endothelin (ET), and total anti-oxidation capability (T-AOC) in the brain tissues were investigated. It is found that the content of NO in the Shuigou EA group lowered, ET decreased and the T-AOC raised significantly in both the Fengfu EA group and the Shuigou EA group (all P<0.05) as compared with the model group, indicating that acupuncture can reduce the contents of ET and NO, and increase the T-AOC in the brain tissues of the rats with cerebral hemorrhage.
