17.NATURE has many ways of reminding us who is in charge.Her most deadly weapons - bacteria,viruses,and parasites(寄生蟲) - claim millions of lives every year.
But thanks to the hard work of great scientists,mankind could turn nature against itself.And it is for exactly this sort of work that the Royal Swedish Academy of Sciences awarded the 2015 Nobel Prize in Physiology or Medicine on Oct 5.
Half of the prize was awarded to the Irish William Campbell and the Japanese Satoshi Omura for discovering avermectin(阿維菌素),a drug that kills the parasitic worms that cause river blindness and lymphatic filariasis(象皮?。?Chinese scientist Tu Youyou shared the other half of the prize for developing Artemisinin,a drug that helps kill the parasite that causes malaria.
Omura is a microbiologist by training.He studied Streptomyces bacteria to find compounds(化合物) that work against harmful microbes(微生物).Campbell,working in the US,took bacteria found by Omura and took out avermectin,which is effective against parasites in farm jye.aiimals.An improved type of avermectin was later produced for humans,which greatly reduced the cases of river blindness and lymphatic filariasis.
Avermectin comes from bacteria,but artemisinin comes from plants.Its discovery was the result of Project 523,a Chinese government project to find a new malaria drug in the late 1960s.
Malaria is a mosquito-borne disease caused by parasites,which attack red blood cells,causing fever,and sometimes,brain damage and death.Tu and her team made 380 herbal extracts from 2,000 recipes from traditional Chinese medical books.In 1971,after more than 190 failures,Tu's team finally found an extract that was 100 percent effective against malaria parasjye.aies.It was called qinghaosu,later renamed artemisjye.aijye.ai.In 2001,the World Health Organization named artemisinin the first choice in the treatment of malaria.
Millions of people are still troubled by infections caused by parasites.But the WHO said that by 2013,malaria deaths had fallen by 47 percent compared with 2000.Similarly,river blindness used to be one of the leading causes of preventable blindness.These days,doctors are talking about chances of wiping the disease off Earth.All of these achievements would not be possible at all without the drugs that Campbell,Omura and Tu helped to discover.
