摘要
The effect of high dose dexamethasone(5 mg/kg wt,intravenous injection)to preventand treat secondary pathological damage due to craniocerebral injury was studied in an animal modelof craniocerebral injury caused by high-velocity missiles in dogs.We observed the physiologicalchanges,analyzed the level of serum and cerebrospinal fluid lactate dehydrogenase,cstimated thepermeability of blood brain barrier(BBB)and studied brain pathology by light and electronmicroscopy.The rusults suggest that high dose dexarnethasone can help to restore the structure andfunction of BBB,protect the brain cells,lessen the secondary pathological damage in the respiratoryand circulatory systams,and reduce the production of lipoperoxides(LPO).
