Effect of edaravone on cerebral edema and lipid peroxidation in rats of cerebral hemorrhage / 中国生化药物杂志

ABSTRACT

Objective To discusse the effect of edaravone for brain tissue oxidative damage after cerebral hemorrhage through observing the hemorrhage rats back edema and the change of lipid peroxidation.Methods 150 healthy and clean male SD rats, were randomly divided to sham operation group,control group,treatment group,50 cases in each group,each group choose five time points,post operative 0.5 day,1 day,2 days,3 days, 4 days,observed different 10 rats at each time point.The intracerebral hemorrhage model was made by using the method of stereotactic autologous blood injection.The changes of water content, the content of MDA and the activity of superoxide dismutase were monitored in three groups at different time points.Results Surrounding the hematoma in the brain tissue around the hematoma after intracerebral hemorrhage in sham operation group,treatment group of postoperative day 1-4 days each time hematoma surrounding brain tissue water content was significantly lower than that in control group(P<0.05);Control group after 2 days of cerebral edema and reached the highest value;Sham operation group and treatment group of postoperative half of the day to 4 days each time the content of MDA were significantly lower than in control group ( P <0.05 );Sham operation group and treatment group postoperative half of the day to 4 days each time the brain tissue SOD activity was significantly higher than control group(P<0.05).Conclusion The effect is obvious that edaravone for cerebral hemorrhage rats brain tissue around hematoma edema, reduce cerebral hemorrhage rat tissue oxidative damage.
