Animal research

10 important questions on Animal research

What kind of research questions are mainly answered with animal research? (3)

  1. Basal questions; before going into translational and clinical research.
  2. Testing a new drug => effectiveness
  3. Testing a new drug => safety testing

When are you allowed to use animals for your research?

1) convincing scientific justification => it will give a lot of new important insights
2) expected benefits outweigh potential risks
3) scientific objectives cannot be achieved using non-animal methods

What is the history of animal law?

1938 → Federal Food, Drug, and Cosmetic Act (FDA) → requiring safety testing of drugs on animals before marketing
1977: Dutch law on animal welfare
1986: European law on animal welfare
2010-current: revised and strict Eu

What are animal experiments; by law?

  • Vertebrates and chephalopods =>inktvissen
  • Risk of discomfort
  • Which may cause the animal a level of pain, suffering, distress or lasting harm equivalent to, or higher than, that caused by the introduction of a needle in accordance with good veterinary practice.
  • A known or unkown outcome
  • Scientific purpose as described in EU Directive 2010/63

Is testing cosmetics and sunscreen an animal experiment?

No, this is not allowed.
Testing the effect of a new sunscreen on the skin of pigs

Where can you find what procedures you have to follow? And what do you need for your research?

EU Directive 2010/63
=> clear research question

If you develop a new drug, do you need animals?

Yes, by law this is necessary. FDA 1938. You usually use two species, one rodent and one non-rodent.

What are the levels of discomfort? And why is this important?

  1. Non recovery = performed entirely under general anaesthesia. and is humanely killed without regaining consciousness
  2. Mild = short-term mild pain, suffering or distress + no significant impairment of the well-being
  3. Moderate = short-term or long term moderate pain, suffering or distress + Moderate impairment of the well-being
  4. Severe = severe pain, suffering or distress, or long- lasting moderate pain, suffering or distress • Severe impairment of the well-being

What is the level of severity when: you don’t know the cause of death?

Always severe.

In practice; how to come to the 3R's?

  • Fasten/accelerate the development of new models and tools based on the latest science and technologies => support new ideas in all ways
  • Carefully look at study designs so that you don't have to do it again and that it really adds something to the field => so you reduce the number of animals
  • Improve animal welfare by the latest technologies.
  • Improve understanding of welfare

The question on the page originate from the summary of the following study material:

  • A unique study and practice tool
  • Never study anything twice again
  • Get the grades you hope for
  • 100% sure, 100% understanding
