  #1 Old 07-10-2007 Default Organ Donation

Recently the papers have been publishing reports of the successful heart transplant conducted in IJN.

Organ donation is a very noble action IMO, but the numbers of organ donors and blood donors in our country is still low.

I believe more education and awareness may increase these numbers. Blood donation drives should be made more frequent as well.

What do you guys think?

could mechanical hearts and artificially manufactured blood substitute the real things? and what about grown and harvested organs?

anyway, good luck to hui yi and the guy who got the lungs! and many thanks, and condolences to the donors and their families.

One thing i do know is that mechanical hearts can't get close to the level of control a real heart does. Your heart beats faster and slower according to environmental stimula, but mechanicals have a fixed rate i think.

Grown and harvested organs won't be here as long as there is that ridiculous ban on stem cell research in the US is going on. The only thing that is successful now is skin. Don't know if there are any others.

I am not aware of artificially manufactured blood. Some of the blood antibodies and certain proteins could be taken from animal sources or be produced by genetically engineered bacteria; but blood cells per se and many other things have not really been artificially produced at all.

Anyway, about artificial heart, I don't know much about the subtleties as it's not widely used and not really taught in my medical school, and I don't really know whether it's already possible for artificial hearts to respond to nervous signals from the autonomous nervous system. This is a wiki article which gives you some brief (not well-written) overview about artificial heart:

I guess in the near future it will be possible, I've heard lectures from some scientists on these technologies but they are still rather far ahead from becoming commercially viable. Not to mention there are many areas that needs to be refined.

That's true, while real hearts are linked to the CNS via the sympathetic and parasympathetic systems, mechanical hearts are not. But i'm not sure of the details.

Anyone here would donate their organs after death?

Any organ which could be donated. But I guess this brings us to the issues of donation of organs "which would deface the body" such as cornea etc.
