Pros And Cons Of Xenotransplantation

1557 Words7 Pages

Xenotransplantation is a medical procedure that involves the transplanting of living cells, tissues or organs from one species to another. Xenotransplantation includes many different forms of animal to human transplants such as the transplanting of organs and cell which may include the transplanting of pigs neural and pancreatic islet cells, tissue transplants and bridging transplants. While the technology providing xenotransplantation gives hope to curing many fatal diseases it also carries potential health risks. The procedure also raises ethical issues about the treatment of animals. In New Zealand research into xenotransplantation has been underway and there are organisations that are for it and some that are against it. In my report I …show more content…

Due to the lack of human organs available for transplants patients have had to wait longer for an organ and can therefore risk dying in the time that they have to wait. However due to xenotransplantation if animal organs and their cells are able to be used instead of humans the time that the patients would have to wait for a suitable organ could be shortened therefore potentially saving their lives. Xenotransplantation can also hold some potential risks such as physical and immunological risks while also involving a risk of disease. Physical issues involve anatomical and chemical differences between the human body and the body of the animal from which the part was donated while immunological issues are the things that could arise due to how the body’s immune system reacts to the presence of an unfamiliar piece of matter being in the body. With the physical issues in terms of cell transplants these physical problems are often fewer however there can be issues in terms of organ transplants. Issues can arise from the donor species differences in things such as organ size, body temperature, body pH and hormones. The range of these differences result in how successful the transplant is going to be. For example pigs blood is a different temperature than humans and due to them walking on all fours their organs are adapted to different positions to those of a human, these differences could cause issues with the transplanting of these parts of a pig into a human. In terms of immunological issues involved the human body in order to project the body from diseases is programmed to destroy foreign organisms such as viruses. Transplants can also be recognised by the body’s immune system as being foreign and therefore could try to destroy

Stem Cell Research: Pros And Cons

Therefore, it is a problem that will arise since there will be conflicts between people as a result of differing opinions. Certain religions consider it to be immoral. From the point of view of a Christian they have concluded that the status of an embryo is similar to that of a human because it will become one and thus they should be treated with respect thinking of the human it will become. The main concern for religious groups as such from all religions is that through this they are “playing god”. They believe that messing with Gods will is erroneous and this will cause problems to arise between different groups who oppose the opinion therefore stem cell transplants are better off avoided and only tested in the laboratories but not performed on humans.

Pros And Cons Of Therapeutic Cloning

511 Words | 3 Pages

Therapeutic Cloning is the replication of human embryos to harvest stem cells for medical uses. Therapeutic Cloning allows an individual’s own cells to be used to treat or cure that person’s disease. It is the removal of a nucleus which contains the somatic cell. A somatic cell is any cell of a living organism except the reproductive cells. One of the many goals of cloning is to bring extinct animals back but there’s been so much controversy over the reason for and how it will put humanity in danger.

Both ethically and morally, some people are not ready to welcome this procedure. Many social movements are protesting for the animals? rights. People are against exploiting animals for the use of humans. Some even claim that thousands of monkeys, chimpanzees and baboons have been experimented on and killed in the course of this cross-species transplant research (Animal welfare and animal rights, n.d.).

This risk not only affects the organ receiver but also everyone that comes in contact with the recipient “creating new and dangerous diseases” (par.17). The main problem with Xenotransplantation is that they use pigs which “harbor a variety of other known and unknown bacteria and viruses” (par.18) transferring into human DNA. No good is going to come from using a foreign organ in a human’s body since most likely the “recipient's immune system is suppressed” causing the organ to “be

The disease raises many scientific and ethical questions. When scientists are studying ethics of Xenotransplantation and consider new technology they overlook many basic questions. They also look over the broad question that raises risks and is difficult to evaluate and is very important to consider. The organ transmission also has many risks. Since transplant patients now have to use immunosuppressants, that raises a risk to the environment.

With technology improving, the death rate will drop significantly for those who are not able to acquire an organ from a human donor. Surgeries using body parts from animals can be risky to those who will be willing to be a test subject, patients in the past who received organs from animals were known to only live a couple of days after the transplant. Luckily scientists are able to see what went wrong by using past failures to help them with future organ transplants using

Similarities And Differences To The Nacirema Culture

When professor Linton brought forth the attention of anthropologists to the Nacirema culture there was a lot of things about their traditions that were different than that of our own, but that doesn’t mean that there aren’t also some similarities as well. As crude and vastly spiritual these people are it is rather impressive that they managed to survive for as long as they did living their rather extreme lifestyle. The people back then also had different social classes like we do now, they also had what we call surgeons to fix their imperfections, and they also have the same kind of cleanliness as we do when it comes down to our bodies. Some differences would be in their rituals we don’t go to those extremes to make sure we are okay spiritually. We also don’t believe that if we don’t take care of our teeth no one will love us.

Organ Donation Ethics

When dealing with this issue, it should not be forgotten that this is a discussion of life and death, where a decision is made on who lives, who dies and why. This issue is also regarding real people who are suffering, and decisions made based on good ethics and proper understanding of social and religious aspects will facilitate and make the process less painful. Both the community and physicians should therefore approach organ transplant positively and objectively and treat ethical, social and religious issues as negotiable perspectives and not barriers to organ

Synthesis Paper In 1954, the first live donor transplant surgery in the United States occurred ("Our Flesh and Blood"). Since then, hundreds of thousands of lifesaving transplants have been successfully performed. Transplants have become a main factor in the controversy that scientists are pushing the bounds of nature too far. Fear of failed surgeries leads critics to oppose medical advancements, but it is not society’s place to interfere with saving lives.

The Pros And Cons Of Organ Transplantation

ORGAN DEMAND AND SUPPLY Few would argue against the proposition that kidney transplantation is the most successful and least expensive mode of treating end-stage renal failure. Moreover, in some parts of the world today, transplantation is the sole treatment option. The need for organs is incontestable, but a serious shortage is being faced everywhere and it seems likely to persist until xenotransplantation becomes a realistic option. Thus, it seems rational that any practice which enhances the number of kidneys available for transplantation must be examined and regarded as beneficial unless it carries with it overriding bad consequences.

Ethical Issues Of Xenotransplantation

In the short term, demand of transplants can be met (Groth et al., 2000; Fix, n.d.; Cooper, 2015), which would reduce the number of patients on waiting lists for transplants. Using cross species transplantation can improve the quality of life that some people have. While transplants may not be flawless, as mentioned later in this article, they can ‘buy time’ for patients on waiting lists (The National Health and Medical Research Council, 2003). This can give people who may otherwise lose their life some time to enjoy things and fulfil their dreams or enjoy their final moments. Although this does not appear to be impressive to those of us with greater health, for the less fortunate it means everything (Groth et al.,

Cloning at the gene level is acceptable and is done extensively in research areas. However, therapeutic cloning and reproductive cloning raises skepticism and debate both in the general society and the scientific community. Among the argument raised is the possibility of cloning human beings; whether the individuals derived are seen as a complete human with the whole set of human rights attached to them. Body >>> Scientific Advantage <<< 2 PAR Fiester (2005) states that most of the animal cloning projects are driven by the goal of meeting human needs such as treatment of diseases, food production, and entertainment.
