Delve into the ethical debate on animal experimentation, exploring both sides of the argument, key benefits to humans and animals, and the importance of regulations and ethical considerations. Understand the impact of animal research on medical breakthroughs, training future healthcare professionals, and enhancing animal welfare. Discover how the 3Rs principles—Replacement, Reduction, Refinement—are implemented to minimize animal suffering while maximizing scientific outcomes. Explore historical perspectives, Nobel Prize achievements, and the future of animal experimentation with a balanced view.

Animal rights activists NO! • it causes suffering to animals; • the benefits to human beings are not proven; • experiments violate the rights of animals; • any benefits to human beings that animal testing does provide could be produced in other ways; • animals surely deserve to live their lives.
YES! ANIMAL RESEARCH SAVES LIVES SUFFERING DURING EXPERIMENTS IS MINIMIZED!!!

Animals are used to: • understand how diseases affect living tissue • develop and test treatmentsfor human andanimals • train future health-care professionals

Good science and good animal care go hand-in-hand • Good science requires a good animal care. • Animals that are in poor condition, discomfort or pain are poor research subjects. • Animal well-being supports the integrityof the research.
We seek a cure for diseases Only clear regulations and policiescan reconcile both sides and help to ensure the human treatment of animals They see a rat in a cage Kehinde EO, Med Princ Pract. 2013;22 Suppl 1:52-61
REGULATIONS OF ANIMAL EXPERIMENTATION Animal Experiments Directive 2010/63/EU on the protection of animals used for scientific purposes
Animal Experiments Directive 2010/63/EU on the protection of animals used for scientific purposes „It is essential, both on moral and scientific grounds, to ensure that each use of an animal is carefully evalueated as to the scientific or educational validity, usefulness and relevance of the expected results of that use” „The likely harm to the animal should be balanced against the expected benefits of the project”

The 3 R’sprinciples Rex LeonardBurch. William Moy StrattonRussell and 1959 Replacement Reduction Refinement
Replacement • computer-based systems & mathematical modelling; • cell, tissue and organ cultures; • use of lower organisms (bacteria and fungi) • physico-chemical techniques; e.g., the commercial test system EYTEX can predict whether a chemical will irritate the eyes,
Minimizing the number of animals used in experimentsby: improving experimental and data analysis techniques; information (to reduce unnecessary duplication of animal work); performing pilot studies to determine some of the potential problems in an experiment before numerous animals are used; gathering a maximum amount of information from each animal, using the appropriate species of animal so that useful data are collected Reduction
improving animal welfare in laboratories; refining experimental protocols to minimize pain or distress whenever possible. Refinement
Local Ethics Committees for Experiments on Animals • determination of the level of severity; • consideration of humane endpoints; • determination of the indispensability • of the experimental proposal; • classification into applied or basic research; • determination of the probability of success • cost-benefit analysis
1. Determination of the level of severity • non-recovery (anaesthesia); • mild (short-term mild pain) • moderate; • severe
A human endpoint It can be defined as the point at which an experimental animal's pain and/or distress isterminated, minimized or reduced, by taking action such as euthanasia the animal humanely, terminating a painful procedure, or giving treatmentto relieve pain and/or distress.
Determination of the indispensability of the experimental proposal There are no alternative ways!
5. Determination of the probability of success. 6. Cost-benefit analysis - pain, - suffering - distress Potential benefits of experiments on animals to humans, other animals and enviroment Rollin B.: Animal research: a moral science. EMBO reports, 2007;8:521

Using animals for research activities is a privilege, not (and) a right! It is important to keep focusing on the continuous improvement of the wellbeing of laboratory animals, as well as further development ofreplacement alternatives and regulations for animal experiments.
