a scientific suggestion to save life of alive people- plz comment

I have seen many needy people standing in the line in medical institutes for kidney but with diappointed hearts. I have also read cases of people killing for taking out their body parts like kidney, eyes etc. But for kidney isn't their anything like pace maker which can be used as an artificial replacement for saving life. Please comment

Pallavi, as far as I'm aware the only machine available for kidney treatment is dialysis.
A dialysis machine acts as 'artificial kidney' by removing excess waste products from the blood and getting the osmotic balance as close to healthy as possible.
The problem is our kidneys work constantly to filter the blood but we cannot strap someone to a dialysis machine constantly (they're pretty bulky and would limit what you could do to such a large extent)
Basically the kidneys are incredibly complicated organs, we can't reach that level of complication in such a small space at the moment. There are lots of other reasons why we can't make artificial kidneys for implant yet but I'll just become even more boring if I keep going.
Someone please tell me if I've made a stupid mistake in that. I've got an exam which has a load on kidneys next week so I don't want to mess anything up in it.

Dear Colom,
I can understand that u have a kidney exam and with your research you will definitely pass the exam cause if you have been able to find my article and comment then you are really on this subject yourself too and i am sure a person with so much of concentration always passes the exam. I only wish to bring the attention of a lot of people in general that kidney is a very important part of the body and without its proper functioning any one can die of toxic waste and in this age of computers where chips of micro mini sizes are being made why and how come they have not been able to find any solution to make an artificial kidney till date. Because of this problem people kill each other and kill some one to continue life of another. So this problem should be dealt with as soon as possible. I have a suggestion. Dialysis is very expensive and only way to keep the process continous is to give artificial one may be in the beginning a bigger one outside the body. Even the computer was very big in the start of computer age now hand tops are avalaible. So.................

I'm not saying an artificial kidney is impossible, just that it is at the moment...
An organ is a group of tissues in an organism that have been adapted to perform a specific function. These tissues all depend on each other, whilst there is some technology at the moment to synthesise tissues from stem cells there isn't any way to connect them together in a way to form anything as complicated as the kidney yet.
Think of how many individual parts make up the nephrons, how many layers are part of the kidney and how hormones effect it.
(If you don't know much about the workings of the kidney, a good place to start is always something like wikipedia)
Kidneys are far more complicated than a computer chip, for us to create a kidney we are going to really increase our understanding of genetics and growth. So maybe one day.. but not quite yet

I believe there is ongoing research that focusses on nanofilters. Organic cloning is another option.

I understand that you are talking about a save environment for the people suffering from sugar or people who might have been attacked by 2% to 10% of kidney failure but what about those whose kidneys have failed by more than 75% to 90% or even 100% for that matter. Organic clothings do help a great deal i agree but people do not have knowledge of how to maintain economic balance and work upon producing wheat that is essentials of living , how do you think they will think on sowing seeds for production of cotton. I think there has to be some definite artificial way to conclude on this problem Plz comment?

Artificial replacement? No, but they are working on something better:
Bio-ink printer makes stem cells differentiate
* 13:00 11 December 2006
* NewScientist.com news service
* Richard Fisher
An inkjet device that prints tiny “bio-ink” patterns has been used to simultaneously grow two different tissues from the stem cells of adult mice. Surgeons could one day use the technology to repair various damaged tissues at the same time, the researchers say.
Inkjet technology uses a fine stream of droplets to build structures and is employed across many industries – from computer chip design to large scale manufacturing.
It also has biomedical applications: researchers use it to place very precise amounts of biological material, on the microscale. For example, some groups have used the technology to print cells, and “build” organs (see Print me a heart and a set of arteries, and Replacement organs hot off the press).
Now, Julie Phillippi at Carnegie Mellon University in Pennsylvania, US, and colleagues have demonstrated a novel bio-ink printer that directs a population of muscle-derived stem cells from adult mice to differentiate into both muscle and bone tissue. It is the first such system to grow multiple tissues from a single population of adult stem cells, the researchers say.
The technique works by firing various patterns of different growth factor proteins onto the stem cells. By tweaking the spatial patterning of the doses, using different print-heads to deliver various concentrations of the protein “bio-ink”, the cells can be directed to differentiate into different tissue types, says Phillippi.
