Introduction

B3 Transplants Question 1 Since 1950, there had been many attempts to successfully transplant organs and tissues, only a few of these transplants are successful, here is the list of the successful transplants since 1950: 1954: First successful kidney transplant 1966: First successful pancreas transplant 1967: First successful liver transplant 1967: First successful heart transplant 1981: First successful heart/lung transplant 1983: First successful lung lobe transplant 1984: First successful double organ transplant 1986: First successful double-lung transplant 1995: First successful laparoscopic live-donor nephrectomy 1997: First successful allogeneic vascularized transplantation of a fresh and perfused human knee joint 1998: First successful live-donor partial pancreas transplant 1998: First successful hand transplant 1999: First successful Tissue Engineered Bladder 2005: First successful partial face transplant 2006: First jaw transplant to combine donor jaw with bone marrow from the patient. 2008: First successful complete full double arm transplant 2008: First baby born from transplanted ovary. 2008: First transplant of a human windpipe using a patient's own stem cells. 2008: First successful transplantation of near total area (80%) of face, (including palate, nose, cheeks, and eyelid) 2010: First full facial transplant, 2011: First double leg transplant. ...read more.

Science and technology may help overcome problems such as these because of the research being done into the possibility of Xenotransplant, this is when an organ is transplanted from one particular species to another. Many scientists believe that pigs would be the best use for this purpose, as some of their organs are similar in size and we already use heart valves successfully for replacing those damaged in humans. Advantages of using animals as organ donors for humans Once medical xenotransplantation will become available, the demand and the supply for organs will be equivalent and therefore it will be possible to offer transplantation to all the patients on the waiting list. Many of the patients in different countries wait years for an organ, by using animals as organ donors for humans, all of the transplantation can be performed without any delay and therefore death on the waiting list will be avoided. Another advantage of using animals as organ for donors is that many diseases and viruses that affect humans but not animals can be stopped. Animal donors can be genetically engineered to fight selected diseases and therefore make the human body immune to those diseases. ...read more.

Conclusion

However the human immune system will attack any pig tissue. http://www.uktransplant.org.uk The disadvantages of using animal's organ donor for humans is that there's a small possibility of primates diseases with the transplant to the human which could seriously harm the patient and could even cause a large epidemic. Some religions such as Islam do not accept humans to have a pig's organ because it's seen as dirty and unclean. Many people believe that animals too have rights, just like humans, and therefore have the right to live without fear of murder and not be killed off for the purpose of helping humans by providing organs for transplants and therefore we should not exploit the animals for our benefit. http://www.pbs.org In my opinion I think xenotransplantation is an excellent idea. We have yet to know what affect this will have on the environment and future generations. On the other hand if you use a animals organ it easily makes up for the shortage of organ donors, it will cut people off the waiting list. We also understand about animal biology so we can use them, it is also easier to get a match. We eat animals such as sheep cow etc so there should be no objection to why we should not use animal's organ for transplant. ...read more.

  2. Does cloning benefit or endanger society?

    There isn't a general consensus about when a human's life starts and therefore pro-cloners cannot disregard the idea that an embryo is life. In therapeutic cloning, all of the embryos used are destroyed, whether the process works or not; if it works, it will become a tissue, if it doesn't work, it will be disposed of.
