I am curious, as to what everyone thoughts are about the future of medicine. I was just thinking today, can I sort of "do what ever I want", now, and not have to worry about the long term effects of it, twenty, thirty, forty, even fifty years from now, because medical technology will be so great, and will be able to heal me? I mean, I read an article, about artificial blood, thats in testing right now, which is given to trauma victims. For instance, if a patient is suffering from head trauma, you give them this and it delivers %34 more oxygen to the brain, then regular blood. This has already saved many lives, and greatly reduced inevitable brain damage to victims, who would otherwise had died, or been extremely mentally damaged. Such things like this, and with amazing medical discoveries being made every day, when do you think mankind will get to the point of having super-human life spans. Or even, just not having to worry about getting in a bad car accident, because technology is so advanced, we can just, "fix" you. Another thing... In biology this last week, we talked about an article entitled "Miracle Grow". Its about a new powder that supposedly helps "regrow" amputated limbs. A man got the tip of his finger cut off, working, and he got to the hospital, and he couldnt find it, so they couldnt reattach it. The mans brother in law was a lead scientist in this powder, and sent him some. Sure enough, 4-5 days later, the finger tip had regrown, just as it was, fingernail and all. The article brought up some very intriguing points.
Supposedly, the powder uses something similiar to stem cells, which are basically blank cells, which are not coded to become any specific tissue, and can therefore, adapt to the area where its applied, and grow accordingly, recieving instructions from the exsisting cells DNA. Another interesting topic was, when humans are in the womb, there is not an inflammatory response to trauma, but instead, a regenerative response. So, its essentially like the tails of some lizards, if they get chopped off, then they simply grow back. However, the body mysteriously seems to 'switch' to the inflammatory response after the 6th month or so in the womb. So now doctors are trying to use gene therapy to discover the mechanism that controls the switch, and if its possible for there not to be a switch.
This sort of technology is already being applied to soldiers in Iraq, who have suffered from massive skin burns, and this 'powder' is sprayed on, and the skin starts regenerating, and they heal, strikingly well. Our class had a two and half hour debate on this topic in class, and I am curious as to what everyone's thoughts are, as well as what your thoughts are for the previous topics....So, have at it!
