| Research Abstract |
Once a stroke happens, there is virtually no effective treatment except for thrombolysis within 5 hrs after the crisis, but its application ratio is less than 5%. We noticed that most of serious after effects of stroke are caused by the ischemic delayed neuron death starting from 2 days after the crisis, and aimed to develop therapeutic drugs that can protect neurons from ischemic damages. By using animal models with transient brain ischemia, we found that certain neurosteroids, when administered within 48-72 hrs after the crisis, could largely inhibit the ischemic delayed neuron death and learinig/motility impairment. Furthermore we revealed the underlying molecular mechanisms of the neuroprotective effects of the neurosteroids.
