Transcript of XENOTRANSPLANTATION
In Xenotransplantation there are many pros and cons being looked about, many advances being established, many different animals and body parts being tested, and many hopes, risks, and precautions taking place.
Applicable Body Parts
One of the challenges that the scientists face is choosing the right organ or body part. Some of the most common implanted tissues or organs are the heart, the liver, lungs, pancreas, and the intestines, . There are some tissues that can be donated as well, such as the cornea, skin, heart valves, and tendons.
Advances are being made in order to resolve the main problems in xenotransplantation. Scientists are trying to genetically modify the animals that are being used in xeno so that the organs transplanted into the patients’ bodies to preserve the organs or tissues from dieing in the patient’s body. Another change in xenotransplantation is that natural chemicals are being used on the animal organs in attempt to stop them from being rejected. The effects of the chemicals will wear off eventually, but, thanks to these changes, nonhuman body parts are lasting much longer in the human body than before.
What is Xenotransplantation?
Xenotransplantation is " the process of grafting or transplanting organs or tissues between members of different species."
Pros and Cons
Xenotransplantation has both pros and cons.
There are also several downsides to xenotransplantation. The main one is the problem of rejection. Although scientists have figured out a way to keep organs alive within another kind of organism’s body, the transplanted organ or tissue is still foreign to the patient’s body. Our body has a natural defense system to reject anything that is not familiar, and often xenotransplantation triggers this reaction, leaving the organ useless in the patient’s body. Another flaw in xenotransplantation is the fact that animals have short life spans compared to humans, so of course the animals’ organs or tissues, even if not rejected, would not remain alive as long as needed.
The word Xenotransplantation originates from the Greek word"xeno-" meaning
, so the word "xenotransplantation" means the transplantation of foreign body parts.
Risks, Hopes, and Precautions
People who are getting a xenotransplantation face many
Some risks include the transmission of known or yet as unrecognized xenogeneic infectious agents from animals to human beings and from recipients of xenogeneic transplants to their contacts and the public at large. Another really big risk is immune rejection. Also, since pigs and most other animals die at a young human age, the transplanted organs can stop functioning.
In some cases, xenotransplantation is the only hope for patients, depending on which kind of illness or disease they have. Xenotransplantation patients will have he hope of a longer, healthier life; hopefully, they will also treasure their life more too, and not make bad decisions.
There is one simple precaution to avoid being forced to get xenotransplantation - take care of yourself. Eat the right foods, stay away from drugs, and get plenty of exercise. Easy things. However, these precautions can go a long way- they can go far enough to the point where they prevent you from needing xenotransplantation; just because you didn't follow these simple steps throughout your life and your unhealthy organ to be replaced with a pig's in order for you to live.
Organ transplants - replacng diseased organs, such as heart, lungs, liver, pancreas, or kidneys
Cell transplants - replacing damaged or dead cells in diseases such as diabetes, Alzheimer's, or Parkingson's disease
Tissue transplants - replacing skin, corneas, blood, blood vessels or bone
There is an immense number of animals in the world, therefore being a large supply of organs and tissues available for people who cannot wait on the waiting list for a human donor, and must get a transplant immediately. Xenotransplantation may be a good option for these people and doctors around the world, as the population of animal donors greatly outnumbers the population of humans.
When scientists first tried xenotransplantation, they tried using monkey and chimp organs, thinking that since monkeys and apes are the most human-like creatures, apart from humans, on Earth. Using chimps wasn’t very successful, because of their lack of ability to reproduce in labs and zoos, so scientists tried using pigs, because pigs can be very well “bred in captivity”.
Xenotransplantation has helped hundreds of people around the world. There are still problems, but advances are also still improving xenotransplantation everywhere. However, it is still best to take make wise, healthy choices so you can keep your own organs and tissues safe and clean. However, until this message is passed around the world, xenotransplantation continues to support many people and save lives everyday.
