The procedure for "updating" the blood does not work, scientists of the United States. In the experiment, they gave old mice the blood of young animals. Any positive results in the end could not be obtained.
Note, not so long ago many scientists were convinced that aging can be stopped if an elderly person constantly enter portions of young blood and drain the blood old. As it turned out, it's impossible.
No change in the body when the blood transfusion occurs. Moreover, frequent blood transfusions can trigger an immune rejection reaction and a significant deterioration of health.
For starters, scientists plan to find out what changes generally can occur in the body of an elderly person after the introduction of young blood cells. Unfortunately, the elixir of youth remains elusive within contemporary science project.
