RE: [PSUBS-MAILIST] What ever became of the haemosponge?



Oh boy, I actually remember hearing about that on a VOA short wave radio program in the early eighties when I was a teenager in Argentina. The material was a sponge impregnated with hemoglobulin, the same stuff that is in red blood cells. The diver was not going to breathe water, but wear a canister of hemosponge on his back instead of a HP tank. The O2 would be extracted from the water to breathe in gaseous form. 
 
BTW on the same program, they spoke of a table that had been finished in a coating of living cells. If you scratched the table finish, it grew back and healed itself.
 
How I can remember an individual radio broadcast from over 25 years ago, I have no idea. Normally I can't remember what happened yesterday.

As far as I know the substance was a type of syntetic blood based on a Fluor compound.  It worked well with guinea pigs and mice but the problem is the flour compound is also toxic so it can only be used for a short time.
To breathe under water is not possible, the experiments with mice were very promising but the animals died of exhaustion after a while.  Water is much dense than air and our diphragma is not strong enough to move the amount of water needed to do the oxigen exchange. Water contains also much less oxigen than air.
That is what I read about this topic some years ago. I hope is usefull.
