日本学者07Nature MedOhsawa et al. 2007)文章发表后,立刻引起我们的极大兴趣。我们采用不同的脑缺血模型,验证呼吸2%氢气是否可治疗脑缺血损伤,研究结果与日本学者的结果类似,证明呼吸2%氢气确实能够治疗新生儿缺血缺氧后损伤。该内容已发表文章,见Cai JM, Kang ZM, Liu W, et al. Hydrogen therapy reduces apoptosis in neonatal hypoxia-ischemia rat model. Neurosci lett 2008,441(2):167-172. 文章发表后,立刻引起关注,目前已经被引用6次。

这个文章是我们的第一篇关于氢的文章, 比日本学者第一篇晚了1年. 但是我们的速度也是比较快的.

Abstract: Hypoxia-ischemia (HI) brain injury is a major cause of neuronal cell death especially apoptosis in the perinatal period. This study was designated to examine the effect of hydrogen therapy on apoptosis in an established neonatal HI rat pup model. Seven-day-old rat pups were subjected to left common carotid artery ligation and then 90 min hypoxia (8% oxygen at 37 °C). Immediately after HI insult, pups were placed into a chamber filled with 2% H2 for 30 min, 60 min, or 120 min, respectively. 24 hr after 2% H2 therapy, the pups were decapitated and brain injury was assessed by 2,3,5-triphenyltetrazoliumchloride (TTC), Nissl, and TUNEL staining, as well as caspase-3, caspase-12 activities in the cortex and hippocampus. H2 treatment in a duration dependent manner significantly reduced the number of positive TUNEL cells and suppressed caspase-3 and -12 activities. These results indicated H2 administration after HI appeared to provide brain protection via inhibition of neuronal apoptosis.
