Outline of Final Research Achievements

Recent experimental studies showed that Hydrogen can alleviate Early Brain Injury by reducing oxidative stress. On the other hand, intra-cisternal infusion of magnesium sulfate solution shows reversible effect on the delayed angiographic vasospasm. The purpose of this study is to investigate the therapeutic effects of the combination therapy of intra-cisternal infusion of magnesium sulfate solution and intra-venous hydrogen rich fluid, and evaluate whether the therapy can ameliorate the prognosis of patients suffering from severe state of SAH.
On the basic research using animal models, each therapy and combination therapy improved the survival rate and neurological function, and reduced neuronal apoptosis and brain edema by reducing oxidative stress at 24hours after SAH.
In our institute, a clinical study of a randomized and placebo-controlled design is in progress now. As it is a development process, each therapy shows favorable therapeutic effects, especially in reducing vasospasm.
