Animal testing, also known as animal experimentation, animal research and in vivo testing, is the use of non-human animals in experiments that seek to control the variables that affect the behavior or biological system under study.This approach can be contrasted with field studies in which animals are observed in their natural environments or habitats. All rights reserved. Animal testing isn't only benificial for the human himself also for other animals beacause it also helps cure diseases that animals have which are sometimes similair to the diseases of humand for example: asthma that is why animal testing is a good thing and what would you choose your child being tested on or your pet, i think its pretty obvious. If conducted under strict methods with appropriate protocols, animal experimentation can provide reliable evidence on how that animal's physiology or behaviour responds under the experiment's conditions; genetic studies are particularly effective, while behavioural studies can yield less firm conclusions. I understand why animal testing could be a good idea. Animal studies in science are experiments that control an animal's behaviour or physiology for study, often to serve as a model for human biology where testing on humans is impractical or unethical. Animals themselves benefit from the results of animal testing. The former CEO of the Medical Research Council, Prof Colin Blakemore, stated that "[primates] are used only when no other species and no alternative approach can provide the answers to questions about such conditions as Alzheimer’s, stroke, Parkinson's, spinal injury, hormone disorders, and vaccines for HIV" Without animal testing, victims of many diseases will become hopeless. The main pro for animal testing is that it helps researchers find treatments to improve medicine and health. Repeated trials are taken and also subjected to high doses to see the lethal effect. There are several reasons why the use of animals is critical for biomedical research: • Animals are biologically very similar to humans. These all owed a huge debt to animal research. Privacy Policy. Google “cosmetics tested on animals in 2017,” and amazingly, you won’t get zero results. Animal testing has made many medical treatments possible, including cancer and HIV medications, insulin, antibiotics, vaccines and many more. Why We Should Accept Animal Testing Nowadays we all take for granted the medical breakthroughs of the 20th Century: diphtheria and polio vaccines, antibiotics, modern anaesthetics, … This is obviously because animals don’t have the gift (or curse) of knowledge that we humans hav… Concerns surrounding experiments using animal models are often based on the morality of depriving animals of their liberty or subjecting them to pain or discomfort, to meet a human need or value. So the chances of the animal suffering is high and also most of them are killed. Unlike testing in humans, animal research is so thorough and harsh. For one they do know what limitations there are while experimenting on animals and can tell how that will effect the results. Two, they only get to the stage of testing on animals after they collect data through in vetro processes and computer programs that stimulate how the drug might effect the body. At an extreme end of the ethics spectrum is the claim that all animals have rights equal to humans, and therefore any experiment that wouldn't ethically be conducted on humans shouldn't be conducted on any animal. Animals are not good models for human medicine. Despite many decades of studying conditions such as cancer, Alzheimer’s disease, Parkinson’s disease, diabetes, stroke and AIDS in animals, we do not yet have reliable and fully effective cures. But with robust debate and reliable review procedures, they will steadily make animal testing - and the ethical and practical problems they bring - a thing of the past. Animal experimentation A difficult issue In 1997 Dr Jay Vacanti and his team grew an ear on the back of a mouse Animal experiments are widely used to … This doesn't make animal models useless. Ethics boards today tend to weigh up the potential benefits of an experiment with the risks of harm and suffering to the animal. Research on living animals has been practiced since at least 500 BC. Get top stories and blog posts emailed to me each day. However, studies on monkeys aren't yet phased out: In 2017, the US had a record-high number of studies involving monkeys. Human tissue models, such as those making up 3D tissue conglomerates called organoids, are increasingly serving as appropriate models for studying growth and development. There are unregulated parts of the testing industry still around. Humans and animals don't always react in the same way to a drug. When it comes to humans, the first step taken before they participate in any form of research is informed consent. The crux is that in order to make advances in the field of medicine, animal testing is inevitable. Well Treated Animals Give Better Test Results. For example, zebrafish are quick to breed, easy to house, and transparent as embryos - but they also carry 70 percent of the genes found in humans. The species or classification of animals used in testing largely depends on the goal of the experiment. All this makes them suitable for studies on human disease and embryological development. Animal treatments that were developed using animal testing also include remedies for glaucoma and hip dysplasia, as well as pacemakers for heart disease. There is some truth to this. But the fact remains that currently animal research can still be necessary for progress in medical research. This novel finding takes us another step closer to developing potential treatments by shedding light on Alzheimer disease in people with Down syndrome, and in the rest of us. List of Cons of Animal Experimentation. However, the close likeness of non-human primates to ourselves also means their use in experiments is the most controversial of all types of animal testing. Generally, this means that human subjects have to sign a form stating that they agree to the terms and conditions of the experiment, and are willing to participate in the research. Experiments that apply the findings to human biology require significant assumptions on whether any differences between them are significant. Easy to raise and breed, their mammalian physiology and genomes overlap even more considerably with those of humans, making them suitable models for studying behaviours, toxicology, and the effects of medical treatments. Rodents have a long history of being used for science experiments, and today make up around three quarters of all animal subjects in testing. Medical scientists use many methods, including computer models, cell cultures, DNA chips and human studies to better understand human and animal bodies, and the diseases which affect them. The human body is incredibly complex -- an intricate maze that is not replicated by any other species. In some cases the animal experiments are performed specifically due to legal requirements. So why the increase in numbers? The reason why animals are used in testing products that will be used by humans is the physical make-up of animals that has a great degree of resemblance to that of the human body. All potential medicines must be safety-tested on animals before they are tested in humans. Failure rates from animal research activities in all … But when it comes to conducting potentially life-threatening experiments on animals, there is no system of informed consent here. The last decade has seen a large rise in both private and public investment in the life sciences. Tests on animals play a vital role”. More than half a century ago, zoologists William Russell and Rex Burch suggested experimentation should become more humane by following the three Rs; restrict when to use animals; refine the kinds of experiments conducted on them; and replace as the technology becomes available. New research opportunities have also supported this rise, with genetically modified animals, which are able to more accurately model aspects of diseases, now accounting for almost half of all research animals. for purposes of research into basic biology and diseases, assessing the effectiveness of new medicinal products, and testing the human health and/or environmental safety of consumer and industry Animals are good research subjects for a variety of reasons. The support for animal testing is based largely on anecdote and is not backed up, we believe, by the scientific evidence that is out there. All the human patients suffered life-threatening side-effects which didn't appear in animals. To deal with this, the UK has implemented strict regulations to provide some of the highest animal welfare standards in the world. Animals are used to develop medical treatments, determine the toxicity of medications, check the safety of products destined for human use, and other biomedical, commercial, and health care uses. In the past year animal research has been key to many medical breakthroughs including: the Gila monster's (South American lizard) venom is a key ingredient in Lixisenatide, a new treatment for diabetes; genetically modified mice were key to the development of Lonafarnib, the first ever treatment for Progeria (a condition causing extreme premature aging in children); and pioneering research in macaque monkeys has contributed to the possibility of "three-parent IVF treatment", which has recently come closer to being approved to avoid inherited mitochondrial disease. The last decade has seen an 8% rise in the number of animal procedures carried out in Britain. Many people consider animal testing to be Public awareness about animal testing is growing. Nowadays we all take for granted the medical breakthroughs of the 20th Century: diphtheria and polio vaccines, antibiotics, modern anaesthetics, the treatments for childhood leukaemia that have allowed so many children to live full and healthy lives. such tests can identify unexpected side effects and check that the medicine is likely to be safe. I think most people would say an animal test that identified a problem or disease an animal had, so it could be given appropriate treatment, was a good idea. Contributes to Treatments and Cures. Non-human primates, especially chimpanzees and rhesus monkeys, have also been used extensively in scientific testing. The species or classification of animals used in testing largely depends on the goal of the experiment. Other tests estimate effective doses and … © ScienceAlert US LLC. It does mean we ought to be cautious about how results from an experiment based on an animal model might apply to our own bodies. We cannot conclude, beyond a reasonable doubt, that any data derived from animal testing is accurate enough to … Reasons For Animal Testing Medical Advancement: The most obvious advantage of animal testing is for medical experimentation. All research must pass ethical review with lay people to justify the use of animals, and scientists must show how they have considered alternative, non-animal methods before they can receive a licence to use animals for their research projects. Did you know that even items like contact lenses, … Because animal tests are so unreliable, they make those human trials all the more risky. Advances in computer modelling and in-vitro tissue culture design are continuing to provide alternatives to animal models that don't suffer from the same ethical and practical limitations. One of the most significant concerns … One drug, TGN1412, was tested on animals and in humans. An estimated 26 million animals are used every year in the United States for scientific and commercial testing. Animal testing is necessary because alternative methods are currently not as reliable. Generally, testing protocols are often painful to the animal test subjects, where they are deprived of food and water, force-fed, physically restrained in long periods, inflicted with pain and wounds to test for healing process effects and remedies, and even purposely killed as part of the process. All this makes them suitable for studies on human disease and embryological development. Given these strict conditions, we have to be realistic and accept the rise in animal research this year as a necessary step towards the medical treatments of tomorrow while continuing to develop new methods to reduce numbers in the future. While harder to reproduce in large numbers and challenging to house comfortably, experiments on our closest evolutionary relatives can yield valuable information on a wide range of issues, from drug toxicity to neurology. It uses cruel and inhumane treatment. However, animal testing increases demand for more effective products. Animal research does bring up a critical ethical dilemma: does the likely benefit of the research outweigh the likely harm to the animal? Text and images may be altered, removed, or added to as an editorial decision to keep information current. 1.Pain & Suffering: Animals have to undergo severe suffering during testing. Pros of Animal Testing 1. There can also be a sex imbalance, with much of rodent research done only on male mice, for example. This investment has resulted in rises in both animal and non-animal methods being used in medical and veterinary development. For this animal testing is very crucial, because it helps in understanding this virus. Moreover, animal testing has also been instrumental in saving endangered species from extinction. In fact, mice share more than 98% DNA with us! Animals are used for transportation, for sport, for recreation, and for companionship. For example, zebrafish are quick to breed, easy to house, and transparent as embryos - but they also carry 70 percent of the genes found in humans.
