American this year will swallow 15, 000 tons drugs of
aspirin, one of safest and most effective invented by man. 【M1】______
The most popular medicines in the world today, it is an el- 【M2】______
fective pain reliever. Its bad effects are relatively mild, and it
is cheap.
For millions of people suffered from arthritis, it is the 【M3】______
only thing that works. Aspirin, in short, is truly the 20th –
century wonder drug. It is also the second largest
suicide drug and is the leading cause of poisoning between chil-【M4】______
dren. It has side effects that, if relatively mild, are largely 【M5】______
unrecognized among users.
Although aspirin was first sold by a German company
in 1899,it has been around more longer than that. Hippocra-
tes, in ancient Greece, understood the medical value of the
leaves and tree bark which today are known to contain salic- 【M6】______
ylates( 水杨酸盐), the chemical in aspirin. During the 19th
century, there was a great number of experimentation in Eu- 【M7】______
rope with this chemical and it led in the introduction of aspi-
rin. By 1915, aspirin tablets were available in the United 【M8】______
States.
A small quantity of aspirin ( two five - grain tablets)
relieves pain and inflammation. It also reduces down fever 【M9】______
by interfering with some of the body’s reactions. Specifical-
ly, aspirin seems to slow down the formation of the acids in-
volved in pain and the complex chemical reactions that
cause fever. The chemistry of these acids is not fully under-
stood, and the slowing effect of aspirin is well known. 【M10】______
