medicine counter in the world, it is likely that you will find aspirin and penicillin. both of these medicines have saved millions of peoples lives and have proved beneficial to mankind since they were invented.aspirinaspirin was invented in 1897. however, the basic chemical used to make aspirin can be found in nature. nearly 3，500 years ago, people chewed on leaves or drank a kind of tea made from leaves possessing a special chemical to reduce body pains and fever. about 2，500 years ago, the greek physician hippocrates, father of all doctors, made a juice from a tree bark containing salicylic acid for the same effect. it was in 1897 that a european chemist called dr felix hoffmann produced aspirin from this chemical. the first trials of this medicine took place in 1899, when the company hoffmann worked for began distributing the medicine in powder form to physicians to use with patients. a year later, in 1900, aspirin was sold in shops in the form of tablets. within a short time, aspirin became the bestselling medicine in the world for pain relief.not only has aspirin proved vital for reducing fever and helping stop pain, but there are also other things that aspirin can help with. lawrence craven, a doctor from the usa, introduced the idea in 1953 that aspirin had the potential to reduce the risk of heart attacks, because it helped the blood circulate better. the report was ignored. however, in 1971, smith and willis from the uk proved that aspirin could have that effect, and in 1977 a study carried out in the usa showed that aspirin could prevent strokes, as well. eleven years later, dr thun from the usa showed that aspirin could reduce the risk of some cancers by 40 per cent. in 1999, aspirin was over 100 years old, and yet there have been more discoveries about how it can help increase the length of peoples lives. in 2003, a chinese doctor, dr yuan minsheng, found that aspirin could reduce blood sugar levels and, therefore, help people with diabetes.penicillinanother drug that has helped increase the standard of peoples health is penicillin, which is considered by many to be one of the most important medicines in contemporary society. it was discovered by a scottish scientist named alexander fleming in 1928. he noted that a dish in which he was trying to grow bacteria for an experiment looked abnormal there was blue mould in it. it astonished him to see the bacteria surrounding the mould dead, which meant that the mould had killed them. fleming tried this mould out on another bacterium and found that it killed the bacterium too. he immediately realized that the mould might have an application in treating illnesses caused by bacteria. he named the liquid made from the mould penicillin. however, the development of penicillin as a drug faced two problems. first, he was unable to find a procedure to make penicillin pure enough to work as a medicine. second, it was difficult to produce penicillin in the ample quantities needed to be effective. in 1940, two other scientists, howard florey (australian) and ernst chain (germanborn english), helped solve these problems, and managed to make and test the new drug in large quantities. since the new drug was needed for world war ， the government approval process for penicillin was accelerated, and mass production began in 1944. due to the widespread use of penicillin, many lives were saved during the war. if penicillin had not been available, many people would have died from sickness or even small wounds. penicillin became the greatest drug of the 20th century, saving millions of lives.in 1945, the three scientists, fleming, florey and chain, shared the nobel prize in medicine for their work.两种挽救生命的药物这篇文章将着重讲述两种开始给医学界带来巨大变革的药物。只要打开世界上任何一个药柜或者到任何一个卖药的柜台，你可能就会发现阿司匹林和青霉素。自这两种药物被发明以来，它们已经挽救了数百万人的生命，而且造福于全人类。阿司匹林阿司匹林发明于1897年。但是，用于制造阿司匹林的基本化学物质可以在自然界中找到。将近3
