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.
澳大利亞漏斗網蜘蛛的毒液可以在15分鐘殺死一個人。但它也可能預防中風腦損傷。
Scientists noticed a molecule in the spider's venom looks a lot like another chemical known to protect brain cells.
科學家發現蜘蛛的毒液分子看起來很像另一種能保護腦細胞的化學物質。
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.
所以他們做了科學家該干的事，他們在老鼠身上測試了該分子。結果是相當令人鼓舞的。科學家們發現，中風后處理八小時該化學物質能夠預防部分腦損傷。
Most strokes occur from a blockage or narrowing of arteries in the brain, and that's the kind scientists looked at in this study.
大多數中風發生在大腦動脈堵塞或狹窄，科學家在對此進行研究。
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.
他們還需要測試該化學物質對處理血管破裂導致中風的有效性。未來兩年可能不會進行人體試驗。
