Periodic Observation for NO Level and NOS Activity in Serum and Brain Tissue of Rats Damaged by Cerberal lschemic Reperfusion with Naoluotong

Abstract:

It was studied that the mechanisms of Naoluotong on preventing and treating cerebral ischemicreperfusion damage rats.The cerebral ischemic model with Qi-dificiency and blood stasis syndrome was established to observe the level of nitric oxide (NO) in serum and brain tissue,and the activity of nitric oxide synthase (NOS) of brain tissue through chemical colorimetric method.The results show that Naoluotong can remarkably raised the level of NO in serum,and decreased the level of NO and the activity of NOS in brain tissue.
