Of life is an eternal dream of mankind, then in the end there is no life-prolonging drugs can really do? British "Daily Mail" reported on the 8th, the United States a few days ago scientists found a drug called rapamycin have may have to extend the human life span 10 years of magical effect.

can extend the life span of experimental rats

authoritative academic journal "Nature" said, several American scientists nearly 2000 20-month (equivalent to Human 60-year-old) were divided into two groups of experimental rats, in which a group of food mixed with rapamycin, does not increase the other group. The results showed that rapamycin intake increased by an average life span of rats by 14%.

Rapamycin is an immunosuppressive drug, in 1975 scientists from Chile, Easter Island's soil will be extracted from it. Easter Island is considered the world's most mysterious places on the island more than 600 stands a huge statue, it was suspected that an alien left behind on Earth to visit.

rapamycin commonly used in the prevention of organ transplant rejection occurs when, some studies have shown these drugs can extend yeast, nematodes, fruit flies and other invertebrate life. But this time found that it can effectively extend the life span of mammals, also is the first time.

before scientists have found there are two ways to extend the life of mammals: "repair" genes and by controlling the diet to reduce fat intake. And they suspect that rapamycin is able to extend the life span of rats because of its "deceit" in the body believe that a reduction of fat intake.

success in 10 years is expected to improve the

although rapamycin may be human have been looking for "longevity medicine", but are unable to conduct clinical experiment. Because the drugs interfere with the immune system, increasing the probability of infection and the body of cancer-induced side effects, which have a higher risk, must be through some kind of "improvement" only allow human use.

It is expected in 10 years scientists have developed improved rapamycin. Once the medical field will be a historic revolution, the existence of the entire human society and the development of great significance.

responsible for the study at the University of Texas, Dr. Alan Richardson said: "I never thought life could be found in the life-prolonging drugs, and rapamycin may have the effectiveness of this. "
