    Abstract:
    The mission of medicine is maintenance of health, elimination of suffering and prolongation of life. These aims can be achieved by medicine based on experimental determination, because only then it becomes a real science. The nature of human mind has led the man since the beginning of humanity on the earth to the cognition of his environment and himself. Being intellectually superior than other living creatures, the man got power over them. In his endless efforts to expand knowledge about living organisms, including his own, he started to use animals. The man has used animals for cognitive purposes for ages and is still doing it, however his motivation has changed and is still changing. Cognition of functions of living organisms on the basis of observation solely, without any interference into the living body gave a lot of important information, yet, generally, this method was of little use for the development of science. Only the use of animals could give information about this what was earlier unknown and impossible. The long-lasting evolution of experimental studies of living functions of higher organisms resulted in achieving a perfect level in biomedical studies. Vivisection, as it was understood years ago, has become history. For a chronic experiment, an animal is surgically prepared according to the researcher's intention. The surgery and the postoperative period follow the principles used in human surgery. After the convalesce period, the animal is used for further experiments. On such prepared animals, the investigations in experimental cardiology, neurophysiology, gastroenterology and other medical disciplines are performed. The animal prepared for longlasting experiments do not suffer from pain during both the experiments and intervals between them. Another important achievement in chronic experiments is considerable reduction of the number of animals used in experimental medicine. Undoubtedly, the greatest achievements in medicine in the 19th and 20th centuries were possible due to the use of animals. There is a strong relationship between a rapid progress in experiments on animals and evident progress in clinical medicine. In the second half of the 20th century the man left the globe for the first time and reached another planet. Tis unusual event in the history of humanity was possible due to space medicine based on biomedical experiments with the use of animals. Also, the man's ability to reach the depths of oceans cost the lives of many experimental animals. Despite advances that have already been made, we are still in the early stages of understanding the complex workings of the body. This makes the replacement of animal experiments a slow process. At the same time, our increasing knowledge is opening up whole new areas of medical research which in turn give rise to a need for further animal use. While it may be difficult to envisage total replacement, the proposition of work that can be done without animals is increasing all the time. Many efforts are being made to find alternatives to animal experiments, to increase the usefulness of those that already exist, and to refine animal research methods. But at present days biomedicine, with its experiments on animals, reveals the laws of nature which the clinical and his patient can use to improve the life quality, prolong the life span and eliminate suffering. We all want to lead a healthy and enjoyable life. Most of us want the benefits of modern medical research-benefits that we would not have without the contribution of animal research. Yet, the health and well being of animals is important too. Clearly, those involved in this research have a moral and legal obligation to ensure that laboratory animals are well housed and cared for, any distress is kept to a minimum and that as few animals as possible are used. In the end, the question of whether animals should be used in medicines research is one everyone must answer for themselves, but the decision is more c
