Due to the need of medical scientific research, it is necessary to study the mechanism of the occurrence and development of human diseases by making animal models, drug screening and treatment evaluation. Because of the differences between animals and people, there are differences in physiological characteristics, So that there will be a different form of expression between the pathological characteristics and the mental emotion, therefore, any animal models can not completely copy all the manifestations of human disease, it is only in one part, one side is similar to human disease. Therefore, the correctness of the animal experiment conclusion is relative. And some drugs in humans and animals on the role or degree of action are more or less the same, let us carefully think about the animal experiments. But we can't deny its application, the purpose is that we should correctly treat and apply animal experiments, we should find differences, avoid misunderstanding, uses the difference, then carry out experimental animal research to contribute to scientific research. The Application of Experimental Animals The experimental animal model is mainly used in the experiment physiology, pathology and experimental research for the treatment of learning (including new drug screening).With the help of the animal model of indirect research, we can consciously change those under natural conditions impossible or difficult to rule out the factors, in order to observe the results of the model more accurately and with a comparative study of human diseases, it is more convenient and effective to recognize the occurrence and development of human diseases, and to study the prevention and cure measures. The main advantages lies in these aspects: It can copy some unusual disease in clinical practice, it is comparable and helps us to fully understand the nature of the disease; Such as some radiation sickness, gas poisoning, traumatism, tumor and some hereditary disease, immunological disease, Metabolic diseases and endocrine diseases, etc., its progress is slow and the incubation period is long, It is very difficult to for more than three generations of continuous observation in the human body. Now people can choose the high incidence rate of the animal in the animal populations, then we can through appropriate means to replicate the disease model for the repeated observation of experimental conditions in human design, research and discussion, to avoid damage to human and animal experiments. We can accord the needs of researchers at any time to understand the whole process of disease samples this is difficult to do clinical and animal experiments. At the same time, Animal laboratory personnel can obtain the same conditions in a certain period of time, a large number of model material, so as to improve the comparability of results and repeatability, make the results more accurate and more in-depth. So in clinical studies in animal experiment, it is an indispensable part. Discuss the Disadvantages of Experimental Animals The development of human diseases is very complex, we explore the mechanism of disease with the person ourselves as the experimental object, promote the development of medicine is slow, also there are some limitations in the clinical experience in both time and space, and many experiments on the moral and method is restricted. And animal experiments tell us the feel are animals rather than human, so that many scientists thinkt animal experiment is not reliable, it is easy to lead to 421 7th International Conference on Education, Management, Computer and Society (EMCS 2017) Advances in Computer Science Research (ACSR), volume 61
