First human, who has died and was subsequently frozen, has been delivered from the United States to Moscow, to be revived in the near future.

The American "patient" of Russian cryonics company is 71-year-old D. Heiko from California. After her death, her body, as requested by children, has been cooled to the temperature of dry ice (-80 ° C). In Moscow, "ice grandmother" has been frozen again, this time to -195 ° C - the temperature of liquid nitrogen. Now her body, along with 35 other "frozen" is awaiting its time inside a sarcophagus at the cryostorage facility in Moscow region.

Ice mummies

"Many famous people believed in successful revivification after flash freezing - told to "AIF" Yuri Pichugin, Ph.D., scientist - cryo-biologist and the head of Russian cryobiology lab. - Robert Ettinger, the founder of cryonics, who has died in the United States, has been frozen in liquid nitrogen. The artist Salvador Dali is known to have been interested in cryopreservation. Walt Disney, science fiction writer Arthur C. Clarke and other famous people have also wished to be frozen. Today, in the United States, there are over 240 cryopatients - dead people who have either their body, or their head, or brain frozen at -196 ° C. It is possible that a similar procedure has been applied to the brain of M. Jackson, which, according to his relatives' wishes, had not been buried along with the body."

Unusual stories: air of the Altai Mountains can be bought in a can, and your own brain - frozen and stored. There is no shortage of those wishing to give themselves or their close ones "second life on earth" overseas in such an unusual way today, despite steep prices: cryopreservation of the human body costs about 40-250 thousand dollars, and of the head or brain alone - 80-120 thousand dollars. In Russia it is possible to preserve oneself much cheaper: whole body for 30 thousand dollars, and if it is just a part of you - only 10 thousand dollars. Although, according to the skeptics, revivification of cryopreserved people, even in the foreseeable future will be, to put it mildly, problematic.

"Ice crystals tear at the nervous and circulatory systems, the structure of all tissues gets irreversibly changed, - explained to the "AIF" Alexander Lavrin, writer, one of the founders of the "Party of the immortals." - In addition to that, most profound physical and chemical changes take place, all the components of the human body get destroyed. Nazis have conducted similar experiments during the war. The experiments were carried out on prisoners at concentration camps, who were put in deep freeze with the help of special injections. But they did not succeed. However, there are known cases when people, after staying in a very severe cold conditions were hardly showing any signs of life, but were still alive - there was blood moving under the skin, although in a very condensed state. It proved possible to return them to normal life."

In the "gray area"

Despite everything cryobiologists still promise success to their customers. "The results of studies of nerve tissue using electron microscopy show that the primary cell matrix is preserved after cryoconservation. Thus, there are chances to revive the whole body, even if with side effects, - says Danila Medvedev, futurologist, one of the cryonics companys' top management. - In the 80-ies cryobiologists in USA and Russia have carried out hypothermia experiments on dogs and rats, who were kept for 2.5-4 hours at a subzero temperature, and were put in the actual state of death with no blood supply to the brain nor brain activity.

After "defreezing" animals behaved quite normally. The point has been reached when this technology is tested on patients in American hospitals: a person is made "temporarily dead" for an hour - hour and a half, while cooling their body, in order to buy time to get them to the hospital in case of, for example, severe blood loss. "

Something similar, is, by the way, happening in IVF clinics: a significant proportion of embryos, which are later implanted in women, are stored in liquid nitrogen. Tens and hundreds of thousands of people were born from defrozen oocytes. Apart from that, some body tissues are put through cryonic treatment as well, to be later used for transplantation.

So who gets "frozen" - living people, or those who are already dead? "Cryopreservation of humans aims to be conducted in the so-called "gray area" between life and final, biological death. From a legal point of view - it is conducted on the dead. However, even though doctors may state brain death, "in some places" the person is still alive, the cells have not yet begun to decompose and there occurred no completely irreversible changes to the body", - cryobiologists explain.

According to cryobiologists predictions, revification of the first "frozen" will occur "as early as 2050, and even more probably - in 2100-th." And it shall be witnessed by those who will be able to live long enough to reach this historic moment.
