Russian recovery frozen frog heart technology leader

Russian scientists pioneered the recovery of the frozen frog's heart during the development of an indefinite preservation technique for human tissues and organs.

Professor Anatoly Keftong, head of the Russian Prospects Research Foundation Project Group, said: "We are developing technologies that will separate isolated tissues and organs indefinitely and maintain their activity. We are proud that we have taken the lead A successful resuscitation of the frozen frog's heart that survived for 45 days at minus 196°C was performed."

In addition, they also restored cardiac activity in rats after 24 hours of cryopreservation at 4°C, which was previously recorded for 6 hours. The researchers emphasized: "We successfully transplanted the cryopreserved heart into rats."

Cofton said that this achievement may set off a revolution in the field of resuscitation medicine because long-term cryopreservation of tissues and organs for subsequent transplantation is a major problem that needs to be tackled urgently.
