[ti:Homemade Soup May Fight Malaria][by:shang05.com][00:00.00]更多听力请访问shang05.com[00:00.04]A new study suggests that some homemade soups[00:05.48]– made of chicken, beef or vegetables — might help fight malaria.[00:13.68]Jake Baum of the Imperial College London led the research.[00:18.92]He asked children at a London school to bring in homemade clear soups[00:25.80]that their families would make to treat a fever.[00:30.72]The children were from many different cultural backgrounds.[00:36.84]The soups were then exposed to the parasite that creates 99.7 percent of malaria cases in Africa,[00:47.28]the World Health Organization, WHO, explained.[00:53.56]Of the 56 soups tested, five were more than 50 percent effective in containing the growth of the parasite.[01:04.40]Two were as effective as one drug now used to treat malaria.[01:10.64]And four soups were more than 50 percent effective at preventing parasites[01:17.52]from aging to the point that they could infect mosquitoes that spread the disease.[01:26.04]Baum and his team reported their results recently in the publication Archives of Disease in Childhood.[01:37.32]"When we started getting soups that worked — in the lab under very restricted conditions[01:44.84]— we were really happy and excited," Baum said in an email to Agence France Presse.[01:54.64]Baum also noted that it was unclear which foods made the soups effective against malaria.[02:03.72]"If we were serious about going back and finding the...ingredient, like good scientists,[02:11.00]we'd have to do it in a very standardized way," he said.[02:17.04]The soups came from families from different ethnic histories, including Europe, North Africa and the Middle East.[02:26.00]They had several main ingredients, including chicken, beef and green vegetables.[02:35.92]Baum said the vegetarian soups showed similar results to the soups with meat.[02:43.72]Baum said his aim was in part to show children that scientific research[02:49.96]can turn an herbal cure into a man-made medicine.[02:56.76]He noted the research of Dr. Tu Youyou of China.[03:02.04]In the 1970s, she found that the herb quinhao was an effective antimalarial treatment.[03:11.16]The herb has been used in Eastern medicine for two thousand years.[03:18.40]Tu's research led to the manmade drug artemisinin, a drug now widely used to treat malaria.[03:27.60]She won the Nobel Prize in 2015.[03:32.88]More and more people are becoming resistant to the drugs that treat the disease,[03:38.72]which kills about 400,000 people a year.[03:43.44]That means scientists will have to "look beyond chemistry" and find new drugs, Baum adds.[03:52.68]I'm Susan Shand.[03:55.00]更多听力请访问shang05.com
