Abstract:
Free radicals are downstream mediators of several cytotoxic cascades contributing to ischemic brain injury. Molecular hydrogen (H2) is an antioxidant potentially useful in the treatment of stroke. Hydrogen is easy to deliver, biologically non-toxic and diffuses freely through all biological structures including the blood-brain barrier and cellular membranes. This study evaluated the efficacy of hydrogen treatments in a rat stroke model compared to vehicle-treated controls using multiparametric MRI and neurological tests. Additionally, comparison of H2 treatment alone was made with H2 combined with minocycline (H2M) treatment (12 rats per group). The primary findings were: i) H2 therapy reduced infarct volume in both H2 and H2M groups compared to controls at 1 and 7 days after stroke, and ii) both H2 and H2M improved neurologic functional recovery on day 7. The secondary outcomes were: iii) H2M treatment attenuated post-stroke hyperperfusion in the hyperacute phase, and iv) H2M markedly minimized white matter injury. In conclusion, this is the first study to use MRI to longitudinally study H2 and H2M treatment on ischemic stroke and the first study to compare H2 treatment combined with another potential stroke therapeutic (H2M).| Publish Year | 2020 |
