  • Brovincamine is a selective cerebral vasodilator that was apparently produced via a slow calcium blockade. Brovincamine has been shown to increase ATP production and glucose and oxygen consumption in brain, improving energy metabolism. Also brovincamine inhibited platelet aggregation induced by ADP and collagen in vivo and in vitro via an increase of cAMP concentration, promoting therapeutic effects on cerebral circulatory disorders. So we investigated and represented the clinical effects and safety of brovincamine in patients with cerebral stroke. Thirty patients of cerebral stroke that was older than 2 months, who were 22 cases of cerebral infarction, 6 of cerebral embolism that originated from carebral infarction, 6 of cerebral embolism that originated from cardiac diseases, and 2 of cerebral embolism that originated from cardiac diseases, and 2 of cerebral hemorrhage, were administered of 20 mg of oral brovincamine three times daily for 8 weeks. Improvement rates of each symptom after 8 week administration were 30.8% for subjective symptoms, 76% for psychiatric symptoms and 65.6% for neurologic symptoms. In final global improvement rates, much improvement was 10%, improvement was 23.3% slight improvement is 36.7%, and no change was 30%. So global improvement rate including slight improvement was 70%. As for side effects, there were 3 cases of mild gastrointestinal symptoms, but there were no other subjective side effects and significant fluctuation in laboratory examination. Conclusively throughout the present study, brovincamine is judged to be well tolerated and effective in patients with cerebral stroke.

  • The purposes of this study were to examine whether balance training through stabilization exercise had influence on the improvement of stroke patients' ability in balancing, and to understand whether the effects had the differences to traditional balance training, if it had effects. Subjects were divided into two groups, a stabilization exercise group(n=28) and a conventional balance exercise group (n=28), and a balance exercise program was conducted twice a day, 30 min for 1 time, 10 times a week for 4 weeks. After the program, the stabilization exercise showed significant improvement of balance ability in Bug Balance Scales (BBS), Functional Reach Test (FRT), Timed Up and Go Test (TUG), comparing with the status of pre -training, as well as the conventional balance training (p<.05). Independent samples t-test was executed in order to verify the significancy in the effects between the two groups and the result showed significant improvement in their average value after training for BBS. However, there was no significant difference in TUG and FRT. As a result, it was examined that partially, there was significant difference only in BBS. According to the results as presented above, if stabilization exercise, which can apply diverse movements and postures, properly keeps pace with conventional balance exercise, stroke patients would obtain significant effects on the improvement of balance ability.
