Vivisection : failing human and non-human animals alike. Beauty Without Cruelty Defending Animal Rights www.bwcsa.co.za
Beauty Without Cruelty www.bwcsa.co.za The two most common illnesses in the Western world are lung cancer from smoking and heart disease. Neither can be reproduced in lab animals.
Beauty Without Cruelty www.bwcsa.co.za The results from animal tests are routinely altered radically by diet, light, noise, temperature, lab staff and bedding. Bedding differences caused cancer rates of over 90% and almost zero in the same strain of mice at different labs.
Beauty Without Cruelty www.bwcsa.co.za Thousands of safe products cause birth defects in lab animals – including water, several vitamins, vegetable oils, oxygen and drinking waters. Of more than 1000 substances dangerous for lab animals, over 97% are safe in humans.
Beauty Without Cruelty www.bwcsa.co.za One of the most common lifesaving operations (for ectopic pregnancies) was delayed 40 years by vivisection.
Beauty Without Cruelty www.bwcsa.co.za The practice of true vivisection dates back to ancient times. Around 500 B.C., one of the earliest known vivisectionists, Akmaeon of Croton, discovered that the optic nerve is necessary for vision by cutting it in living animals.
Beauty Without Cruelty www.bwcsa.co.za Galen, of the 2 nd century ACE, remembered today for his pioneering use of vivisection of animals to understand health and disease in the human body, was also a poor scientist, failing to identify such major bodily functions as the circulation of the blood. An unquestioning adherence to Galen's false beliefs in succeeding generations of physicians was undoubtedly a major hindrance to medical progress in Europe
Beauty Without Cruelty www.bwcsa.co.za The Empiric school (3rd century BCE–4th century) would reject the study of anatomy and physiology by vivisection, not only on the grounds of cruelty, but also for it’s uselessness. Empiricists believed pain and death would distort the normal appearance of internal organs and criticized the speculative nature of the conclusions drawn from experiments.
Beauty Without Cruelty www.bwcsa.co.za With the beginning of modern science in the 17 th century, animals were used as an easy way of understanding human bodies.
Beauty Without Cruelty www.bwcsa.co.za A strong antivivisection movement in England resulted in the Cruelty to Animals Act of 1876. Emile-Edouard Mouchy, oil painting, 1832.
Beauty Without Cruelty www.bwcsa.co.za The Brown Dog affair was a political controversy about vivisection that raged in Edwardian England from 1903 until 1910. The statue was removed in 1910, resulting in a demonstration. William Bayliss dissected a conscious brown terrier in front of about 60 medical students, according to the antivivisectionists present, but he said there was sufficient anaesthetic. There were series of battles known as the Brown Dog riots.
Beauty Without Cruelty www.bwcsa.co.za Anti-vivisection demonstration in Trafalgar Square, London, to protest the removal from Battersea Park of the Brown Dog statue. March 1910
Beauty Without Cruelty www.bwcsa.co.za Smoking was thought non-carcinogenic because smoking-related cancer is difficult to reproduce in lab animals.
Beauty Without Cruelty www.bwcsa.co.za Animal experiments on rats, hamsters, guinea pigs, mice, monkeys, and baboons revealed no link between glass fibres and cancer. Not until 1991, due to human studies, did OSHA label it carcinogenic.
Beauty Without Cruelty www.bwcsa.co.za Though arsenic was a known human carcinogen for decades, scientists still found little evidence in animals to support the conclusion, as late as 1977.
Beauty Without Cruelty www.bwcsa.co.za Pacemakers and heart valves were delayed in development because of physiological differences between animals they were designed on and humans.
Beauty Without Cruelty www.bwcsa.co.za Animal models of heart disease failed to show that a high cholesterol/high fat diet increases the risk of coronary artery disease. Instead of changing their eating habits to prevent the disease, people continued their lifestyles with a false sense of security.
Beauty Without Cruelty www.bwcsa.co.za Animal studies predicted that beta-blockers would not lower blood pressure, which withheld their development. Even animal experimenters admitted the failure of animal models of hypertension in this regard, but in the meantime, there were thousands more stroke victims.
Beauty Without Cruelty www.bwcsa.co.za Animal-based research delayed the development of the polio vaccine, according to Dr. Albert Sabin, its inventor. The first rabies and polio vaccines worked well on animals but crippled or killed the people who tried them.
Beauty Without Cruelty www.bwcsa.co.za Despite the ineffectiveness of penicillin in his rabbits, Alexander Fleming used the antibiotic on a very sick patient since he had nothing else to try.
Beauty Without Cruelty www.bwcsa.co.za Luckily, Fleming's initial tests were not on guinea pigs or hamsters, as it kills them. Howard Florey, the Nobel Prize winner credited with co-discovering and manufacturing penicillin, stated: "How fortunate we didn't have these animal tests in the 1940s, for penicillin would probably never been granted a license, and possibly the whole field of antibiotics might never have been realized."
Beauty Without Cruelty www.bwcsa.co.za The dose of isoproterenol, a medication used to treat asthma, was worked out using animals. It was much too toxic for humans, 3500 asthmatics died in Great Britain alone due to overdose. It is still difficult to reproduce these results in animals.
Beauty Without Cruelty www.bwcsa.co.za While many, if not most, researchers do not foresee an end to animal experiments in biomedicine, the European Commission has nevertheless set full replacement of animal experiments as an ultimate goal, and the Humane Society of the United States has the optimistic goal of full replacement by the year 2050.
Harvard University have developed a human lung on a chip. The tiny device contains human cells, mimicking the way the human lung works. Because it’s translucent, the chip constitutes a sort of window into the body. This is for drug screening, safety, toxicology and drug discovery in terms of aerosol- based drugs is probably the biggest target.
Beauty Without Cruelty www.bwcsa.co.za “In Silico,” meaning "performed on computer or via computer simulation," is now in common usage in the scientific world. The Virtual Liver and Virtual Embryo can save years, hundreds of animals and millions of dollars to find out if a chemical is toxic.
Beauty Without Cruelty www.bwcsa.co.za Scientists are creating artificial micro-humans that would replace these animals. Up to 90 million animal lives are lost each year due to experiments conducted on them. Some of the cosmetic industry and several chemicals and drugs already conduct their tests on artificial lungs, livers, kidneys, hearts and guts.
