Xenotransplantation
The topic I would like to talk about today is called xenotransplantation. If you haven’t ever heard about xenotransplantation that’s okay, a lot of people haven’t. As you know many of the people who need organ donations need them because of new and old health issues. The worldwide demand for organs far surpasses the supply. A study done by the United Network for Organ Sharing in 2004 found that over one hundred thousand patients could have benefited from an organ transplant but only twenty-nine thousand were available. In the United States alone seventeen patients die each and every day while on the waiting list to receive a donor organ. Scientists have been trying to find a solution for the lack of donated organs. One solution they came up with is xenotransplantation. Xenotransplantation is where they put an organ from one species into the body of a second species. In this case it would be animal to human. The most common animal they would use would be a Pig. This sounds simple right? Well its not as easy as it seems. You have to make it so that the body of the recipient does not reject the new and foreign organ. Besides that you have to worry about diseases, it not working properly and over all, the recipient dying. It is a really great idea and scientists are doing research to make it possible, but as of right now it’s just not safe enough.
Xenotransplantation if ever pronounced safe as a working practice would be an unbelievably huge step in our medical science. It would swing doors open that we have previously been afraid of opening. In the future if xenotransplantation is successful it is expected to be enormously profitable. So successful it could receive a Nobel prize for its inventor. So you may...

...be a great accomplishment it we tied up all of the loose ends and figured out how to make it work I just don’t think its the best choice. Maybe in the future we will know more about stem cells and be able to create an organ out of stem cells! That would probably also be really expensive but at least it would not have any where near the amount of risks that xenotransplantation has. I hope that you learned something you didn’t know in this essay and you can form your own opinion on what you think is right.

When viewing organ donation from a moral standpoint we come across many different views depending on the ethical theory. The controversy lies between what is the underlying value and what act is right or wrong. Deciding what is best for both parties and acting out of virtue and not selfishness is another debatable belief. Viewing Kant and Utilitarianism theories we can determine what they would have thought on organ donation. Although it seems judicious, there are professionals who seek the attention to be famous and the first to accomplish something. Although we are responsible for ourselves and our children, the motives of a professional can seem genuine when we are in desperate times which in fact are the opposite. When faced with a decision about our or our children’s life and well being we may be a little naïve. The decisions the patients who were essentially guinea pigs for the first transplants and organ donation saw no other options since they were dying anyways. Although these doctors saw this as an opportunity to be the first one to do this and be famous they also helped further our medical technology. The debate is if they did it with all good ethical reasoning. Of course they had to do it on someone and preying upon the sick and dying was their only choice. Therefore we are responsible for our own health but when it is compromised the decisions we make can also be compromised.
Thesis: I will explain the history of organ transplants, starting with ancient ideas before modern science until the 21st century.
The medical procedure of Xenotransplantation, (transplanting animal organs into humans) has been happening for many years, this medical practice was proceeding mixed results and mixed views regarding the procedure. In the year 1984, a baby girl whom was named Baby Fae by medical staff, became known world wide for the medical procedure she endured. Baby Fae had a potentially fatal heart problem, she was suffering from Hypoplastic left heart syndrome which is a fatal disease if not treated by surgery, (Time Magazine, 1984). The only way to save her was to replace her failing heart with a healthy seven month old baboon heart. The medical professionals that were working on Baby Fae were excited to be able to perform this Xenotransplantation on the infant. After the procedure Baby Fae was acting like any normal healthy infant would. But unfortunately, the replacement heart surgery wasn’t a true success story as the medical staff had hoped. Baby Fae died 20 days after her surgery because her tiny body rejected the baboons heart, which then went on to cause other fatal damage such as kidney...
This essay is about animal to human organ transplants otherwise known as Xenotransplants. Even though this procedure is meant to save lives, it is giving rise to metaphoric Frankenstein’s monsters and putting some aspects of the Human Race at risk. This essay will discuss diseases that can jump species and cause catastrophic dangers for humans such as Ebola and AIDS which the human population has no resistance towards. I will also explore the different religious view points on Xenotransplantation.
In the world we’re living in today, many kinds of diseases, infections, and viruses are continuously arising. At the same time, scientists are untiringly researching about how we can prevent or cure them. Unfortunately, millions of people have been affected and sick that some of their organs fail that results to the need of organ replacement. Many people have died because no organs have been available to provide the need of organ replacements. The shortage of organ replacement has been a bioethical issue since then and it seems like no solution has been available. However, due to the studies scientists have been conducting, they found the most possible answer to this issue – Xenotransplantation. It hasn’t become very popular all over the
Currently 70,000 Americans are on the organ waiting list and fewer than 20,000 of these people can hope to have their lives saved by human organ transplantation.1 As a result of this shortage, there has been a tremendous demand for research in alternative methods of organ transplantation. Private companies are racing to develop these technologies with an estimated market of six billion dollars.2 Xenotransplantation, or cross-species organ transplantation, appears to be the most likely solution in the near future, and cloned pigs are the main candidates. Pigs and humans have remarkable similarities in physiology, which along with cloning makes pigs strong possibilities for organ donors. A controversial alternative method involves the use of genetically altered headless human beings as organ donors. Although this method may not be developed for some years, scientists are already discussing the necessary technologies. Whether the solution is the cloning of a pig or a human, organ farms may provide us with a solution to our ever-increasing need for donors.
Ethical issues also play a role in the selection of the solutions. Most patients perceive xenotransplantation as an acceptable alternative to transplantation of human organs in life-threatening situations provided the potential benefits outweigh any likely adverse effects on the animals. Xenotransplantation of organs from chimpanzees and baboons has been avoided, because of ethical concerns as chimpanzees are listed as endangered species and the fear of transmission of deadly viruses. Pigs are plentiful, quick to mature, breed well in captivity, have large litters, and have vital organs roughly comparable in size to those of humans. Further there are physiologic similarities between their antibodies to human antibodies, and also since they are already being used in the consumer market, organs have been mainly harvested from pigs. Humans have had prolonged and close contact with pigs, their use for the purpose of xenotransplantation is believed to be less likely to introduce any new infectious agents. Porcine islet cells of Langerhans have been injected into patients with type 1 diabetes mellitus. Porcine skin has been grafted onto burn patients, and pig neuronal cells have been transplanted into patients with Parkinson’s disease and Huntington’s disease.
This article is quite old, I noticed it was from 1995, almost 9 years ago, and I can't believe how much further technology has taken us. There have been many advancements in the stem cell study. It is an even bigger controversy now, however. Scientists have found that the highest concentration of stem cells in a persons body comes from their umbilical cord after they are born. They want to create embryo's and use the stem cells from them to help someone else. To me, this is like the cloning issue. I don't think that we should be cloning people pretty much for spare parts like livers, kidneys, etc. It would be like a factory of torso's. It would be gruesome to go into a place that is full of partial bodies, with no heads or souls, and go harvest organs when the time or need arises. That is just too much. The article was pretty informative, and I did learn many things that I did not know previously.

Organ transplantation is apperceived as one of the most prehending achievements for preserving life in medical history. This procedure provides a means of giving life to patience’s who suffer from terminal organ failure, which requires the participation of individuals; living or deceased, to donate their organs for the more preponderant good of society.

In this paper I will be using the normative theory of utilitarianism as the best defensible approach to increase organ donations. Utilitarianism is a theory that seeks to increase the greatest good for the greatest amount of people (Pense2007, 61). The utilitarian theory is the best approach because it maximizes adult organ donations (which are the greater good) so that the number of lives saved would increase along with the quality of life, and also saves money and time.
Many patients in hospitals are waiting for transplants and many of them are dying because they are not receiving the needed organs. To solve this problem, scientists have been using embryonic stem cells to produce organs or tissues to repair or replace damaged ones (Human Cloning). Skin for burn victims, brain cells for the brain damaged, hearts, lungs, livers, and kidneys can all be produced. By combining the technology of stem cell research and human cloning, it will be possible to produce the needed tissues and organs for patients in desperate need of a transplant (Human Cloning). The waiting list for transplants will become a lot shorter and a lot less people will have to suffer and die just because they are in great need of a transplant....
The procedures that will be the future of modern medicine currently fall into the realms of taboo and fictional. These procedures encompass every aspect of medical science, from exploration of the human body, curing diseases, to improving a person’s quality of life. Many of these procedures are not very well known, while a few have been in the spotlight. These procedures include cloning, nano-robotics, retro-viruses, and genetic manipulation via gene-specific medications. For any serious breakthroughs in modern medical science, we must embrace these new forms of treatment instead of shying away from them. Second, I’ll attempt to explain how these methods and procedures could benefit mankind.
