Animal experiments have always been a sensitive topic. Some people can tolerate experimentation with animals to conduct medical research. However, if animals are used to test the safety of cosmetics or soaps, they will never be tolerated.This helps people identify whether medicines and other products are safe for humans. This kind of experiment has been ancient and is not uncommon, as early as 500 BC. The people used animals to conduct experiments. There is currently no alternative method to detect how a substance will react in a complex organism.So can you use animals to do the test? Personally, I think animal experiments are necessary for these days. I divided the article into four parts. The first part briefly describes what animal experiments are, the second part is the pros and cons of animal experiments, the third part is how to reduce the harm caused by animal experiments to animals, and the fourth part is personal opinions and to sum up.
1.1.1 Definition of animal experiments
Animal experiments refer to the use of animals for scientific research in laboratories to obtain new knowledge about biology or medicine or to solve specific problems. Animal tests must be conducted by or under the guidance of trained personnel with a research degree or technical expertise.
1.1.2 The significance of animal experiments
First, animal experiments are unavoidable in some cases, and each animal needs to be tested before using it. It can neither be directly tested on humans nor can other alternatives be found. Therefore, it is necessary to protect human rights. When the role of the drug is unknown, the drug cannot be used by humans. They must use animals. They must also test the toxicity of some viruses or bacteria. Pathogens also need to be tested in mice and other animals, because these animals reproduce fast and at low cost. Therefore, animal experiments have important value in disease diagnosis and biotechnology research in recent years.
Secondly?internationally, it has become the cornerstone of modern life science research. For many areas of development, animal experiments are indispensable. At present, the exact conditions of experimental animals have been used as a symbol of national science and technology modernization level. Therefore, in the absence of alternative methods, experimentation with animals is for social progress and scientific development. So animal experiments are of great significance.
1.2 Advantages of animal experiments
1.2.1The benefits of animal experiments
220.127.116.11Save human life
Without animal experiments, it would be impossible for people with diabetes to use insulin to save lives. Polio is a disease that afflicts parents around the world. It can cause children to paralyze or even die. It is heartbreaking. Knight(2011) states that “Since the introduction of the appropriate vaccine in the world in 1988, the number of cases of polio has decreased by 99%. This malignant disease makes patients miserable. At present, only three countries in the world are suffering from it.” Parents in other countries can rest easy because their children need just be vaccinated to stay away from the disease. If we did not research on monkeys suffering from this disease, it would be impossible to achieve such extraordinary achievements today.
Treatments for leukemia, antibiotics, anesthetics, and other research advances have been made on animals. Experimenting with animals is not limited to the treatment of diseases. Nowadays, organ transplant surgery has been recognized and become quite common (perhaps surprising). After the first kidney transplant operation was successful, the technique was used in dogs to do experiments.
According to an earlier study (Cohn 2010) it is argued that”It is not only humans who benefit from the experiment. If not initially tested on animals, there will be more than 80 disease-prevention treatments that will never be discovered. These treatments were intended for use in humans but are now being used on other animals, such as vaccination against rabies, parvovirus, and leukemia”. Animal experiments can even save the endangered species. The most remarkable result is the rescue of California vultures and black planthoppers. And these benefits cannot be replaced by other methods.
18.104.22.168 The life cycle of experimental animals is often very short
Most of the animals used in experimental studies (such as mice, frogs, etc.) have a short life cycle and strong reproductive capacity. This means that researchers can not only detect the effect of a particular drug on the animal’s entire lifespan, but even whether it will affect its offspring. (As mentioned above, to prevent the recurrence of such events as thalidomide, it is now required that such drugs be tested in pregnant animals before being marketed.)
22.214.171.124Animals are more suitable for replacing complex human bodies than computer models
The complexity of the human body is so incredible that it is difficult to simulate accurately with a computer model. We can do some critical experiments on cell lines, but this cannot reproduce the complicated process of internal human, but cannot be used to predict the side effects of a substance on the internal organs of the human body.
Taking hypertension as an example, some diseases are complex and changeable. To study it, we must place it in a properly functioning, interconnected biological system. With the development of experimental animal alternatives, the early stages of the experiment rely on computer simulation models to complete, perhaps will become possible. However, it is only possible because how to design and build these models must also be based on the results of animal experiments. The speed of reflection (especially the brain) of some organs goes far beyond what our fastest and most advanced computers can simulate. People tried to build a mouse brain model to run in 10 seconds, but found that the response rate of the rat brain was ten times slower than that of the real mouse. This model is designed with the world’s most powerful computer. It has more processing power than the machines used in ordinary laboratories. At present, computer simulation experiments can replace some of the animal experiments that must be completed before human trials, but by no means all.
Without animal experiments, we may not find these drugs that treat diabetes or asthma today; we may not be able to prevent diseases such as polio; we may not know how to perform organ transplants, nor do we know how to install pacemakers from an ethical perspective In terms of applying experimental results to various clinical stages, it is necessary to verify the feasibility of animals with animals or other alternatives. When they are actually used in humans, they need to be more cautious.
Experimenting with animals may not be the ideal way. We are also trying our best to find alternatives. We also hope that animals do not need to be used for experiments any day. However, in the current situation, animal experiments are still essential.
