Have any mammals ever been reanimated after being cryogenically frozen?

I don't trust the guys at LE they take all your money and screw with your mind.

Kind of on the same topic, the common wood frog can have up to 65% of its total body water frozen and survive multiple freeze and thaws in the winter months.

As for other northern frogs hibernating close to the surface in soil and/or leaf litter, wood frogs tolerate the freezing of their blood and other tissues. Urea is accumulated in tissues in preparation for overwintering, and liver glycogen is converted in large quantities to glucose in response to internal ice formation. Both urea and glucose act as "cryoprotectants" to limit the amount of ice that forms and to reduce osmotic shrinkage of cells. Frogs can survive multiple freeze/thaw events during winter if not more than about 65% of the total body water freezes.

Just thought it would be an interesting addition to the thread about an animal that can naturally enter a form of frozen stasis.

This is seriously scary as hell but their making a serum or sumtin to bring back a human like u inject it in them once they die and they will start breathing again

They replace the blood with a bio-compatible anti-freeze liquid which seeps into the cells and prevents crystals from forming. To revive the creature, all they did was put the blood back in and raise the temperature.

I'm trying to find the link to the story on ATS and other places as it was posted about before, you may have better luck then I

hard to buy it, how do you get the heart going again, once it stops?

That is currently one of the main problems. However, they are considering using artificial hearts or pacemakers, and if the person frozen was a person who died of a heart attack, their heart could potentially be restarted.
