Magical anti-aging drugs
Anti-aging drugs are extracted from a chemical found on Easter Island
Xinhuanet London, July 8th The United Kingdom "Nature" magazine released a new study on the 8th, said that US researchers found that a commonly used immunosuppressive drugs can effectively extend the life of mice, which is the first time that such drugs can be extended The life of a mammal.
According to a communique published on the website of Nature, researchers from three U.S. agencies conducted experiments. They used a total of approximately 2,000 rats. The results show that if you start with a rat that is 20 months old (approximately 60 years old in humans), adding rapamycin to your diet will increase its lifespan by approximately 14%.
Rapamycin is an immunosuppressive drug that is commonly used to prevent rejection during organ transplantation. There have been studies showing that such drugs can prolong the life span of invertebrates such as yeasts, nematodes, and fruit flies.
The researchers pointed out that although studies have shown that rapamycin prolongs the lifespan of mice, it is too early to talk about "longevity drugs" against humans, because the immunosuppressive effects of rapamycin will make users more vulnerable to infection. The invasion of the disease. In addition, the amount of medication is also a problem. The dose of rapamycin is usually 2 to 5 mg per day for humans, and 2.24 mg/kg of body weight per day for experimental rats.
Nature will officially publish this research report in its print edition. (Reporter Huang Hao)
