Abstract:
OBJECTIVE:To study the effects of taurine on oxidative stress and calcium overload induced by cerebral cortex contusion.METHODS:SD rats were randomly divided into normal control group,brain contusion model group,taurine groups(high dose,middle dose and low dose respectively),and nimodipine group.After being fed with corresponding drugs for7days,all rats were subjected to modeling by brain contusion.For intracellular calcium detection,rats were sacrificed2h after modeling,and the brain slices were prepared to fluorescence labeling and confocal microscopy detection.For the detection of oxidative stress,rats were sacrificed24h after modeling,the cortex of contusion side was homogenated and then the activity of superoxide dis?mutase(SOD)and content of malondialdehyde(MDA)were detected through biochemical method.RESULTS:Compared with model group,all taurine groups were shown to have markedly less MDA and intracellular calcium content,and the high dose group had markedly stronger SOD activity.CONCLUSION:Taurine is effective in counteracting the oxidative stress and calcium overload caused by brain contusion.
