The venom from an Australian funnel web spider can kill a person in about 15 minutes. It might also prevent brain damage after a stroke.
澳大利亚漏斗网蜘蛛的毒液可以在15分钟杀死一个人。但它也可能预防中风脑损伤。
Scientists noticed a molecule in the spider's venom looks a lot like another chemical known to protect brain cells.
科学家发现蜘蛛的毒液分子看起来很像另一种能保护脑细胞的化学物质。
So they did what scientists do,they tested the molecule on rats. The results were pretty impressive. The scientists found the chemical could help prevent some brain damage if administered as many as eight hours after a stroke.
所以他们做了科学家该干的事，他们在老鼠身上测试了该分子。结果是相当令人鼓舞的。科学家们发现，中风后处理八小时该化学物质能够预防部分脑损伤。
Most strokes occur from a blockage or narrowing of arteries in the brain, and that's the kind scientists looked at in this study.
大多数中风发生在大脑动脉堵塞或狭窄，科学家在对此进行研究。
They still need to test the chemical's effectiveness at treating strokes that result from ruptured blood vessels. And human trials probably won't start for another two years.
他们还需要测试该化学物质对处理血管破裂导致中风的有效性。未来两年可能不会进行人体试验。
