A drug discovered nearly four years ago that builds muscles in lazy mice may also prevent heatstroke, according to lab research reported. If further tests work out, the compound could help athletes or soldiers who are so sensitive to heat that they could die from exertion on a hot day, its authors say.
美國實驗室研究指出，研究人員近4年前發現有助懶散老鼠肌肉生長的藥物，可能也能預防中暑。研究報告作者表示，如經進一步測試，這種化合物或有助避免對高溫敏感的運動員或士兵在酷熱天力竭身亡。
In 2008, a drug known as AICAR became dubbed the "couch potato pill" after it was found to develop muscles and boost endurance among completely inactive laboratory rodents.
2008年，一種名為AICAR的藥物被發現能促進實驗室中完全不活躍的老鼠肌肉生長且提升耐力之後，獲封「沙發馬鈴薯藥丸」稱號。
In a paper published by the journal Nature Medicine, researchers in the United States said they discovered by chance that AICAR also protects mice against a disorder called malignant hyperthermia. This deadly condition is linked to a basket of flaws in a gene called RYR1.
美國研究人員發表於「自然醫學雜誌」的研究報告指出，他們偶然發現，AICAR也能預防老鼠出現惡性高溫症。此致命症狀與第一型理阿諾鹼受體（RYR1）的諸多基因缺陷有關。
Tests on mice genetically engineered to have the RYR1 mutation found that AICAR worked perfectly in preventing malignant hypothermia, says the study.
這份研究說，針對改造成擁有RYR1變種基因的老鼠進行測試後發現，AICAR對於避免惡性高溫症效果非常好。

這份研究的發現，有朝一日或能引領出一種藥物的研發，可供對熱敏感的年輕運動員或在沙漠中穿戴笨重裝備的士兵當作預防使用。（法新社）
