OBJECTIVE:To summarize the clinical effect of compound glycyrrhizin(CG)on SARS.METHODS:The clin?ical data of73patients with clinically diagnosed SARS(37cases were treated by CG)were prospectively analysed.RESULTS:After CG treatment,the symptoms of dry cough,chest distress and dyspnea improved quickly and the elevated serum level of aminotransferase decreased.The maximal dosages of corticosteroids used in CG group and control group were(354.3?219.8)mg/d and(430?262.6)mg/d,respectively.The average time to occurrence of antibody,duration for reduction of corticosteroid dosage and duration of hospital stay were shorter in CG group than those in control group.There was no significant difference in titer value of antibody between two groups.CG had little effects on WBC,blood sugar and electrolytes.CONCLUSION:CG may be a promising drug against SARS with less side effect.

The occurrence,development and reperfusion treatment of ischemic stroke may damage the structure and function of the blood-brain barrier,leading to increased permeability of the blood-brain barrier,and then having cerebral edema or hemorrhagic transformation,and finally resulting in poor outcome.Quantitative assessment of blood-brain barrier permeability is now available.This article reviews the assessment methods of blood-brain barrier permeability and their application in patients with ischemic stroke.
