| Abstract: | Objective To discover protective mechanism of Ling xie capsule in improving secondary neural injury using cerebral hemorrhages model in rat.Methods:Collagen and heparin combinations compound were injected into rat's nuclei caudate to establish a model of acute cerebral hemorrhage in rat.Intracellular free calciumion (Ca 2 ) i were measured using Fura 2/AM fluoremetry technique,and the contents of SOD,MDA in brain tissue using chemical method,and the content of EAA in hippocampus tissue using HPLC,respectively.Result:We found out Ling xie capsule could decrease the concenrearion of (Ca 2 ) i in injured neural cells,and increase the activity of SOD and reduce the production of MDA in brain tissue,and inhibit the increasing of the content of EAA in hippocampus tissue.These effects were significant analysis statistically ( P<0 05 ).Conclusion:Ling xie capsule was possessed of some productive effect for the rat's cerebral hemorrhage. |
