Guest guest Posted December 30, 2004 Report Share Posted December 30, 2004 hi, I am seeking advice, same old question, someone at work, after finding out that I was vegan, ask me that if It weren't for animal testing, many of us wouldn't be here. Animal testing has extended many of our lives, and If my son was dying, and I knew that a drug that had been tested on animals would save his life, for sure that I would give it to him. I really didn't know what to answer. without sounding stupid. what would've you guys have said? Thanks anouk Quote Link to comment Share on other sites More sharing options...
Guest guest Posted December 30, 2004 Report Share Posted December 30, 2004 Hi, I don't have much time at the moment, so my answer will be brief. I think there is plenty of information regarding medical fraud of vivisection. For example, search Animal rights FAQs on the Internet, like www.animal-rights.com . Also, there are many books. One of the best is: Sacred Cows and Golden Geese: The Human Cost of Experiments on Animals by C. Ray Greek, Jean Swingle Greek, Jane Goodall Also from the same authors: What Will We Do If We Don't Experiment on Animals: Medical Research for the Twenty-First Century and Specious Science: How Genetics and Evolution Reveal Why Medical Research on Animals Harms Humans. Or, just search for " vivisection fraud " on Internet and you will get lost of useful information. Regards, H.

Guest guest Posted December 30, 2004 Report Share Posted December 30, 2004 What follows is a review of the book " What Will We Do If We Don't Experiment on Animals: Medical Research for the Twenty-First Century " The Greeks' newest contribution to the growing debate regarding the most ethical use of limited resources for medical research will be unpopular with the animal-model community. `Unpopular' may be an understatement; they are going to hate it. Whenever the question of using animals in research comes up you can be certain that the animal researchers and their supporters will accuse you of hating children if you criticize their cruelties or even their science. " What else do you suggest? " is their common challenge, " should we experiment or little children, or just let them die? " Indeed, it is in their financial interests to cast any critic as a callous lout. But now, the answers are much clearer. In What Will We Do If We Don't Experiment On Animals? the Greeks explain the failures and risks of basing medicines for humans on the results of experiments on other species. Apparently, the animal researchers are content to let children die from a new drug just as long as it was first developed for and tested on animals. But this is well known already. The new ground in the Greeks newest book is the compilation of modern research techniques that really are providing new insights into human disease and offering potential new cures. Readers are given a tour of truly modern medical research that is grounded in a thorough appreciation of the underlying genetics behind disease and our individual responses to drug therapies. Unlike much of the traditional antivivisectionist literature, the Greeks write from the perspective that we have learned something about human biology from studying animals even if we could have learned the same things in other ways. More importantly, they point out that we no longer wonder what a heart does, and that today we are seeking to understand the roles of the proteins coded for by each organism's unique genetic code. The subtleties that account for differences between species are the same subtleties that explain why a rat, a dog, and a human will each respond differently at the molecular level to any particular drug. But, the real value in the book is not its power to point out the failures and ugly profiteering of the animal modelers, but to give the reader hope by pointing out the growing number of research efforts underway based on modern science. The reliance on the most modern of methods accounts for the fact that an ever-growing number of researchers interested in curing and preventing human disease have turned to non-animal methods based on human biology. For anyone with an interest in leading edge biomedical science, this book will probably become a well-worn reference. - " Anouk Sickler " <zurumato Thursday, December 30, 2004 3:49 AM advice on what to say. > > > hi, > > I am seeking advice, same old question, > someone at work, after finding out that I was vegan, ask me that if > It weren't for animal testing, many of us wouldn't be here. > Animal testing has extended many of our lives, and If my son was > dying, and I knew that a drug that had been tested on animals would > save his life, for sure that I would give it to him. > > I really didn't know what to answer. without sounding stupid. > > what would've you guys have said? > > Thanks > anouk To send an email to - > Quote Link to comment Share on other sites More sharing options...

Guest guest Posted December 30, 2004 Report Share Posted December 30, 2004 change *animal* to Jew, mentally challanged, etc our history is filled with some folks benefitting off of the suffering of others, be it other people er other beings.. if the Nazi's came up with some remarkable cure for some malady, because they did some experiments on say, twins, would the holocaust have been ok? besides..animal testing is flawed...we are all different species, all have different needs and requirements...morphine makes cats hyper fer bacchus' sake ever hear of thalidomide? A critical look at animal experimentationby Murry J. Cohen, M.D., Stephen R. Kaufman, M.D., Rhoda Ruttenberg, M.D. and Alix Fano, M.A. Increasing numbers of scientists and clinicians are challenging animal experimentation on scientific grounds. (1-3) Considerable evidence demonstrates that animal experimentation is inefficient and unreliable, while newly developed methodologies are more valid and less expensive than animal studies.Historical Impact of Animal Experimentation Proponents of vivisection (tests, experiments, and "educational" exercises involving harm to animals) claim that it has played a crucial role in virtually all medical advances.(4,5) However, several medical historians argue that key discoveries in such areas as heart disease, cancer, immunology, anesthesia, and psychiatry were in fact achieved through clinical research, observation of patients, and human autopsy.(6-12) Human data have historically been interpreted in light of laboratory data derived from nonhuman animals. This has resulted in unfortunate medical consequences. For instance, by 1963 prospective and retrospective studies of human patients had already shown a strong correlation between cigarette smoking and lung cancer.(13,14) In contrast, almost all experimental efforts to produce lung cancer in animals had failed. As a result, Clarence Little, a leading cancer animal researcher, wrote, "The failure of many investigators to induce experimental cancers, except in a handful of cases, during fifty years of trying, casts serious doubt on the validity of the cigarette-lung cancer theory."(15) Because the human and animal data failed to agree, this researcher and others distrusted the more reliable human data. As a result, health warnings were delayed for years, while thousands of people died of lung cancer. By the early 1940s, human clinical investigation strongly indicated that asbestos caused cancer. However, animal studies repeatedly failed to demonstrate this, and proper workplace precautions were not instituted in the U.S. until decades later.(16) Similarly, human population studies have shown a clear risk from exposure to low-level ionizing radiation from diagnostic X-rays and nuclear wastes,(17-20) but contradictory animal studies have stalled proper warnings and regulations.(21) Likewise, while the connection between alcohol consumption and cirrhosis is indisputable in humans, repeated efforts to produce cirrhosis by excessive alcohol ingestion have failed in all nonhuman animals except baboons, and even baboon data are inconsistent.(22) Many other important medical advances have been delayed because of misleading information derived from animal "models." The animal model of polio, for example, resulted in a misunderstanding of the mechanism of infection. Studies on monkeys falsely indicated that poliovirus infects only the nervous system. This erroneous assumption resulted in misdirected preventive measures and delayed the development of tissue culture methodologies critical to the discovery of a vaccine.(23,24) While monkey cell cultures were later used for vaccine production, it was research with human cell culture that first showed that poliovirus could be cultivated on non-neural tissue.(25) Similarly, development of surgery to replace clogged arteries with the patient's own veins was impeded by dog experiments which falsely indicated that veins could not be used.(26) Likewise, kidney transplants, quickly rejected in healthy dogs, were accepted for a much longer time in human patients.(27) We now know that kidney failure suppresses the immune system, which increases tolerance of foreign tissues. Nevertheless, the public continues to endorse vivisection, primarily because many people believe that animal experimentation has been vital for most medical advances.(28) However, few question whether such research has been necessary or even, on balance, helpful in medical progress.Contemporary Animal ExperimentationA. Selective Diseases1. Cancer In 1971 the National Cancer Act initiated a "War on Cancer" that many sponsors predicted would cure cancer by 1976. Instead, this multibillion dollar research program has proven to be a failure, and the age-adjusted total cancer mortality rate has been steadily climbing for decades.(29,30) In order to encourage continued support for cancer research - now exceeding two billion dollars annually - researchers and administrators have misled the public. In 1987, the U.S. General Accounting Office (GAO) found that the statistics of the National Cancer Institute (NCI) "artificially inflate the amount of 'true' progress," concluding that even simple five-year survival statistics were misused.(31) For one thing, the NCI termed five-year survival a "cure" even if the patient died of the cancer after the five-year period. Also, by ignoring well-known statistical biases, the NCI falsely suggested advances had been made in the therapy of certain cancers.(31) Commenting on the research program's discouraging results, epidemiologist John Bailar III has stated, "The more promising areas are in cancer prevention."(29) Why hasn't progress against cancer been commensurate with the effort (and money) invested? One explanation is the unwarranted preoccupation with animal research. Crucial genetic,(32) molecular,(33) and immunologic(34) differences between humans and other animals have prevented animal models from serving as effective means by which to seek a cancer cure. Cancer researcher Jerome Leavitt has explained that human cancer "may have critical mechanical differences which may in turn require different, uniquely human approaches to cancer eradication."(33)2. AIDS Despite extensive use, animal models have not contributed significantly to AIDS research. While monkeys, rabbits, and mice born with severe combined immunodeficiency can be infected with HIV, none develops the human AIDS syndrome.(35) Of over 100 chimpanzees infected with HIV over a ten year period, only two have become sick. Even AIDS researchers acknowledge that chimpanzees, as members of an endangered species who rarely develop an AIDS-like syndrome, are unlikely to prove useful as animal models for understanding the mechanism of infection or means of treatment.(36) Other virus-induced immunodeficiency syndromes in non-human animals have been touted as valuable models of AIDS, but they differ markedly from AIDS in viral structure, disease symptoms, and disease progression.(37) Animal researcher Michael Wyand, discussing anti-AIDS therapy, has acknowledged: Candidate antivirals have been screened using in vitro systems and those with acceptable safety profiles have gone directly into humans with little supportive efficacy data in any in vivo [animal] system. The reasons for this are complex but certainly include...the persistent view held by many that there is no predictive animal model for HIV infection in humans.(38) AIDS researcher Dani Bolognesi has concurred, "No animal models faithfully reproduce...HIV-1) infection and disease in humans, and the studies of experimental vaccines in animal models...have yielded disparate results."(39) Human clinical investigation has isolated the AIDS virus (HIV), defined the disease's natural course, and identified risk factors.(40) In vitro (cell and tissue culture) research using human white blood cells has identified both the efficacy and toxicity of anti-AIDS medicines, including AZT,(41) 3TC,(42) and protease inhibitors.(43) Federal law, however, still mandates unnecessary animal toxicity testing.3. Degenerative Neurological Diseases A recent review of four prevalent degenerative neurological diseases - Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis (Lou Gehrig's disease), and Huntington's chorea - revealed that animal models have contributed little, if anything, to our understanding or treatment of these conditions.(44) Vivisection is unlikely to illuminate the causes of these diseases, since induced pathologic findings in animal "models" differ fundamentally from those in analogous human diseases. For example, a leading rat "model" of Alzheimer's disease is produced by creating a surgical lesion in the rat's brain. Unlike Alzheimer's patients, these rats exhibit loss of appetite and motor incoordination. Also, the rats do not develop amyloid neural tangles, which are characteristic of Alzheimer's disease.(45) Similarly, an animal "model" of Huntington's chorea that uses a neurotoxin to kill certain brain cells fails to reproduce any of the three classical symptoms of this disease: involuntary movements, psychological disturbances, and dementia.(44)4. Psychiatry and Psychology Animal "models" of psychology, traditionally employing painful stimuli to study behavior, have been strongly criticized in part because human psychological problems reflect familial, social, and cultural factors that cannot be modelled in nonhumans.(46-52) Indeed, most psychologists disapprove of psychological vivisection that causes animal suffering.(53) Harry Harlow's "maternal deprivation" experiments involved separating infant monkeys from their mothers at birth and rearing them in total isolation or with "surrogate" mothers made of wire and cloth. Their terror and subsequent psychopathology, Harlow claimed, demonstrated the importance of maternal contact. However, this had been shown conclusively in human studies.(54-57) Despite its conceptual shallowness, numerous maternal deprivation studies continue, claiming relevance to human developmental psychology, psychopathology, and even immune and hormone function.(56) Animal models of alcohol and other drug addiction are similarly ill-conceived, failing to reflect crucial social, hereditary and spiritual factors. Pharmacologist Vincent Dole has acknowledged, "Some 60 years of offering alcohol to animals has produced no fundamental insights into the causes of this self-destructive behavior or even a convincing analogue of pathological drinking."(58) "Experimental psychology" continues to rely on painful research on animals, despite clinical psychologists' disregard for the animal research literature. A review of two clinical psychology journals revealed that only (33) of 4,425 citations (0.(75%) referred to animal-research studies.(59)5. Genetic Diseases Scientists have located the genetic defects of many inherited diseases, including cystic fibrosis and familial breast cancer. Trying to "model" these diseases in animals, researchers widely use animals - mostly mice - with spontaneous or laboratory-induced genetic defects. However, genetic diseases reflect interactions between the defective gene and other genes and the environment. Consequently, nearly all such models have failed to reproduce the essential features of the analogous human conditions.(67) For example, transgenic mice carrying the same defective gene as people with cystic fibrosis do not show the pancreatic blockages or lung infections that plague humans with the disease,(60) because mice and humans have different metabolic pathways.(61)B. Toxicity Testing Numerous standard animal toxicity tests have been widely criticized by clinicians and toxicologists. The lethal dose 50 (LD50), which determines how much of a drug, chemical, or household product is needed to kill 50 percent of a group of test animals, requires 60 to 100 animals (usually rats and mice), most of whom endure great suffering. Because of difficulties extrapolating the results to humans, the test is highly unreliable.(62) Also, since such variables as an animal's age, sex, weight, and strain can have a substantial effect on the results, laboratories often obtain widely disparate data with the same test substances.(63,64) In vitro tests could potentially completely replace the LD50.(64-66) The Draize eye irritancy test, in which unanesthetized rabbits have irritant substances applied to their eyes, yield results that are inherently unreliable in predicting human toxicity.(67) Humans and rabbits differ in the structure of their eyelids and corneas as well as their abilities to produce tears. Indeed, when comparing rabbit to human data on duration of eye inflammation after exposure to 14 household products, they differed by a factor of 18 to 250.(68) A battery of in vitro tests would be less expensive and likely more accurate than the Draize test.(63,69) Animal tests for cancer-causing substances, generally involving rodents, are also notoriously unreliable. Science editor Philip Abelson has asked, "Are humans to be regarded as behaving biochemically like huge, obese, inbred, cancer-prone rodents?"(70) Of course, humans are not. Of 19 known human oral carcinogens, only 7 caused cancer in nonhuman animals using the standard NCI protocol.(71) Even different rodent species produce conflicting results. When Lester Lave et al. compared rat and mouse carcinogenicity for 214 chemicals, they found a correlation of only 70 percent.(72) (Chance alone would yield a 50 percent correlation.) An international study demonstrated that in vitro tests are more sensitive and more accurate than animal tests.(73)C. Educational Exercise Animal laboratories are not necessary for teaching biologic and medical material, and studies have demonstrated repeatedly their lack of pedagogic superiority.(74,75) Diagrams, pictures, computer simulations, and interactive videos can replace animal exercises to supplement lectures and reading material. During surgical training, medical students and residents properly begin to learn procedures by observing human operations because of the human's unique anatomical features. To perfect manual skills - such as cutting and suturing - surgical training has traditionally relied on carefully monitored work with human patients. When this is not practical, creative use of human tissues can be an alternative. For example, students can practice microsurgery with human placental tissue.(76) Similarly surgeons can learn new procedures with virtual reality computer systems.(77)Scientific Limitations of Animal Models Animal studies can neither confirm nor refute hypotheses about human physiology or pathology; human clinical investigation is the only way such hypotheses can be tested. At best, animal experiments can suggest new hypotheses that might be relevant to humans.(78,79) But, there are countless other, often superior, ways to derive new hypotheses.(2,78) How valuable is vivisection? The Medical Research Modernization Committee's review of ten randomly chosen animal models of human diseases did not reveal any important contributions to human health.(80) Although the artificially induced conditions in animals were given names analogous to the human diseases they were intended to simulate, they differed substantially from their human "counterparts" in both cause and clinical course. Also, the study found that treatments effective in animals tended to have poor efficacy or excessive side-effects in human patients.(80) Indeed, when MRMC physicians evaluate specific animal-research projects, they consistently find them of little, if any, relevance to the understanding or treatment of human diseases.(44,81-86)MRMC's reviews have revealed that, because animal models differ from human diseases, researchers tend to investigate those aspects of the animal's condition that resemble features of the human disease, generally ignoring or discounting fundamental anatomical, physiological, and pathological differences. Because most disease processes have system-wide effects and involve many interacting factors, focusing on only one aspect of a disease belies the actual complexity of biological organisms. In contrast to human clinical investigation, vivisection involves manipulations of artificially induced conditions. Furthermore, the highly unnatural laboratory environment invariably stresses the animals, and stress affects the entire organism by altering pulse, blood pressure, hormone levels, immunological activities, and myriad other functions.(87,88) Indeed, many laboratory "discoveries" reflect mere laboratory artifact.(9,89-95) For example, artifact from unnatural induced strokes in animals has repeatedly misled researchers.(96) In the 1980s researchers reported 25) compounds that reduce ischemic-stroke damage in nonhuman animals, but none proved effective in humans.(93) Animal tests frequently mislead.(97) Milrinone increased survival of rats with artificially induced heart failure, but humans taking this drug experienced a 30% increase in mortality.(98) Fialuridine appeared safe in animal tests, but it caused liver failure in 7 of 15 humans taking the drug, five of whom died and two required liver transplantation.(99) Animal studies failed to predict dangerous heart valve abnormalities in humans induced by the diet drugs fenfluramine and dexfenfluramine.(100) The General Accounting Office reviewed 198) of 209) drugs marketed from 1976) to 1985) and found that 52% had "serious postapproval risks" not predicted by animal tests.(101) In animal tests of saccharin's carcinogenicity, the weight-adjusted daily saccharin dose given to rats was equivalent to a human's consuming about 1,100 cans of saccharin-containing soda. Such massive dosing itself can result in cancers, irrespective of a compound's actual carcinogenicity at typical human exposure levels.(92) Extrapolating such data to humans is further complicated by the observation that saccharin-induced bladder cancers occurred only in male rats. It was later found that male rats possess a protein in greater quantity than female rats (and lacking in humans) that interacted with saccharin to form irritating crystals in the male rats' bladders that caused cancer. The fact that some rats developed cancers did not (and cannot) clarify whether or not saccharin causes cancer in humans.(102) Scientists recognize that, just within humans, gender, ethnicity, age, and health status can profoundly influence drug effects.(103,104) Obviously, extrapolating data between species is much more hazardous than within species. Consequently, animal studies are reliable at only the crudest levels - such as the ability of strong acids to damage eyes. However, such effects can be assessed easily with in vitro systems. For more subtle effects, animal models are unreliable.(105)Animal Research Risks In addition to squandering scarce resources and providing misleading results, vivisection poses real risks to humans. The mindset that scientific knowledge justifies (and may require) harming innocent individuals endangers all who are vulnerable. Even after Nazi and Japanese experiments on prisoners horrified the world, American researchers denied African-American men syphilis treatment in order to assess the disease's natural progression,(106) injected cancer cells into nursing home patients,(106) subjected unwitting patients to dangerous radiation experiments,(107) and, despite no chance of success, transplanted nonhuman primate and porcine hearts into children, chronically ill, and impoverished people.(108) Psychiatrist Robert Jay Lifton argues that this "science at any cost" mentality may have provided medical justification for the Holocaust.(109) Furthermore, through animal research, humans have been exposed to a wide variety of deadly nonhuman primate viruses. About 16) laboratory workers have been killed by the Marburg virus and other monkey viruses, and there have been two outbreaks of Ebola in American monkey colonies.(110,111,111a) Polio vaccines grown on monkey kidney cells exposed millions of Americans to simian virus,(40) which causes human cells in vitro to undergo malignant transformation and has been found in several human cancers.(112,112a) Ignoring the obvious public health hazards, researchers recently transplanted baboon bone marrow cells into an AIDS patient. The experiment was unsuccessful;(113) moreover, a large number of baboon viruses, which the patient could spread to other people, may have accompanied the bone marrow. Indeed, vivisection may have started the AIDS epidemic. HIV-1, the principal AIDS virus, is unlike any virus found in nature, and there is considerable evidence that its most likely source is either through polio vaccine production using monkey tissues(112,114) or manufacture in American laboratories, where HIV-like viruses were being produced by cancer and biological weapons researchers in the early 1970s.(115) Failing to learn from the AIDS epidemic, many policy makers and industrial interests support animal-to-human organ transplants (from pigs and primates) known as xenotransplants. These have failed in the past, and are likely to continue to fail, because of tissue rejection, the impossibility of testing animal tissues for unknown pathogens, and the prohibitive expense.(116-118) Relatedly, the growing field of genetic engineering includes adding genetic material to animals' cells to change the animals' growth patterns or induce the animals to produce human proteins in their milk, blood or urine. This poses serious human risks, such as exposure to pathogens (viruses, prions [such as those responsible for mad cow disease], and other microorganisms)(119,120) or development of malignancies,(121-123) allergic reactions,(124) or antibiotic-resistance.(125) These concerns may explain the European Union's ban on recombinant bovine growth hormone.(126)Importance of Clinical Research Typically, medical discovery begins with a clinical observation,(8,9) which animal researchers then try to mimic with artificially induced animal conditions.(6) These researchers tend to highlight animal data that accord with the previous clinical finding, while discounting or ignoring conflicting animal data (which are usually voluminous). Although animal research advocates routinely take credit for discoveries that actually occurred in a clinical context,(6) many clinicians have recognized the primary role of human-based clinical research. Reviewing the history of hepatitis, physician Paul Beeson concluded: Progress in the understanding and management of human disease must begin, and end, with studies of man...Hepatitis, although an almost 'pure' example of progress by the study of man, is by no means unusual; in fact, it is more nearly the rule. To cite other examples: appendicitis, rheumatic fever, typhoid fever, ulcerative colitis and hyperparathyroidism.(10) Similarly, key discoveries in immunology ,(11) anesthesiology,(12) first aid,(127) alcoholism(58,128) and psychopharmacology (129,130) were based primarily on human clinical research and investigation. Furthermore, clinical research is the only means by which effective public health education and prevention programs can be developed and evaluated.Non-animal Methodologies In science, there are always many ways to address a given question. Vivisection is generally less efficient and reliable than many non-animal methods, which include:1. Epidemiology (Population Studies) Medical research has always sought to identify the underlying causes of human disease in order to develop effective preventive and therapeutic measures. In contrast to artificial animal model conditions that generally differ in causes and mechanisms from human conditions, human population studies have been very fruitful. For example, the identification of risk factors for heart disease, so important for prevention techniques, derive from epidemiologic study.(131) Epidemiology's potential is illustrated by the growing field of molecular epidemiology. Researchers can analyze cellular and molecular characteristics of those suffering from cancer or birth defects, thereby elucidating the mechanisms and causes of DNA damage and yielding effective prevention and treatment approaches.(132)2. Patient Studies The main source of medical knowledge has always been the direct study of human disease by closely monitoring human patients. For example, cardiologist Dean Ornish has demonstrated that a low-fat vegetarian diet, regular exercise, smoking cessation, and stress management can reverse heart disease.(133) Henry Heimlich has relied exclusively on human clinical investigation to develop techniques and operations that have saved thousands of lives, including the Heimlich Maneuver for choking and drowning victims, the Heimlich operation to replace the esophagus (throat tube), and the Heimlich Chest Drainage Valve.(127,134) Currently, his clinical research includes malariotherapy as a promising treatment for AIDS.(135) Modern noninvasive imaging devices such as CAT, MRI, PET, and SPECT scans have revolutionized clinical investigation.(136) These devices permit the ongoing evaluation of human disease in living human patients, and have contributed greatly to medical knowledge.3. Autopsies and Biopsies The autopsy rate in the United States has been falling steadily, much to the dismay of clinical investigators who recognize the value of this traditional research tool.(137,138) Autopsies have been crucial to our current understanding of many diseases, such as heart disease,(137) appendicitis,(137) diabetes(139,140) and Alzheimer's disease.(44) Although the usefulness of autopsies is generally limited to the disease's lethal stage, biopsies can provide information into other disease stages. Diagnostic needle and endoscopic biopsies often permit safe procurement of human tissues from living patients. For example, endoscopic biopsies have demonstrated that colon cancers derive from benign tumors called adenomas. This is in contrast to the leading animal model of colon cancer, in which there is no adenoma-to-carcinoma sequence.(141)4. Post-Marketing Surveillance Because of computer technology, it is now possible to keep detailed and comprehensive records of drug side-effects.(142) A central data base with such information, derived from post-marketing surveillance, would enable rapid identification of dangerous drugs. Such a data system would also increase the likelihood that unexpected beneficial side-effects of drugs would be recognized. Indeed, the anti-cancer properties of such medications as prednisone,(143) nitrogen mustard,(144) and actinomycin D;(145) chlorpromazine's tranquilizing effect;(146) and the mood-elevating effect of MAO-inhibitor(147) and tricyclic antidepressants(148) were all discovered through clinical observation of side-effects.5. Other Non-Animal Methods In vitro cell and tissue cultures are powerful investigative tools. Between the mid-1950s and mid-1980s, the NCI screened 400,000 chemicals as possible anti-cancer agents, mostly on mice who had been given mouse leukemia.(149) The few compounds that were effective against mouse leukemia had little effect on the major human cancer killers.(150) Today, this wasteful program has largely been replaced with a screen of about 100 in vitro human cancer cell lines, a much less costly and more reliable alternative.(151) Similarly, in vitro tests using cells with human DNA can detect DNA damage much more readily than animal tests.(152) Regarding vaccines, in 1949 researchers discovered that vaccines made from human tissue cultures were more effective, safer, and less expensive than monkey tissue vaccines,(153,154) completely avoiding the serious danger of animal virus contamination.(155) Likewise, many animal tests for viral vaccine safety have been replaced by far more sensitive and reliable cell culture techniques.(156,157) Antibodies have broad research and clinical applications. Researchers use millions of animals to produce antibodies by techniques that cause great suffering. Despite the ready availability of inexpensive in vitro methods, many researchers (who claim to use animals "only when necessary") don't bother to use the humane alternative.(158) Mathematical models using human clinical data are another source of information that is more reliable than data derived from animal studies.(159) Mathematical models use human clinical and epidemiological data to generate hypotheses about complex disease processes. For example, a mathematical model has indicated that there are two distinct types of breast cancer - one very malignant, the other much less so - that look alike under the microscope. This model suggests that the more malignant form requires early diagnosis and aggressive treatment, while excision is likely curative in the less malignant form.(160)Why Vivisection Persists If animal experimentation is of such questionable value, why does it persist? There are several likely explanations. Vivisection is easily published. In the "publish or perish" world of academic science, it requires little originality or insight to take an already well-defined animal model, change a variable (or the species being used), and obtain "new" and "interesting" findings within a short period of time. In contrast, clinical research (while much more useful) is often more difficult and time-consuming. Also, the many species available and the nearly infinite possible manipulations offer researchers the opportunity to "prove" almost any theory that serves their economic, professional, or political needs. For example, researchers have "proven" in animals that cigarettes both do and do not cause cancer - depending on the funding source.(161,162) Vivisection is self-perpetuating. Scientists' salaries and professional status are often tied to grants, and a critical element of success in grant applications is proof of prior experience and expertise. Researchers trained in animal research techniques find it difficult or inconvenient to adopt new methods, such as tissue cultures. Vivisection appears more "scientific" than clinical research. Researchers often assert that laboratory experiments are "controlled," because they can change one variable at a time. The control, however, is illusory. Any animal model differs in myriad ways from human physiology and pathology. In addition, the laboratory setting itself creates confounding variables - for example, stress and undesired or unrecognized pathology in the animals. Such variables can have system-wide effects, skew experimental results, and undermine extrapolation of findings to humans. Vivisection is lucrative. Its traditionally respected place in modern medicine results in secure financial support, which is often an integral component of a university's budget. Many medical centers receive tens of millions of dollars annually in direct grants for animal research, and tens of millions more for overhead costs that are supposedly related to that research. Since these medical centers depend on this overhead for much of their administrative costs, construction, and building maintenance, they perpetuate vivisection by praising it in the media and to legislators. Vivisection's morality is rarely questioned by researchers, who generally choose to dogmatically defend the practice rather than confront the obvious moral issues it raises.(163-166) Animal researchers' language betrays their efforts to avoid morality. For example, they "sacrifice" animals rather than kill them, and they may note animal "distress," but they rarely acknowledge pain or other suffering.(167) Young scientists quickly learn to adopt such a mindset from their superiors, as sociologist Arnold Arluke explains: One message - almost a warning - that newcomers got was that it was controversial or risky to admit to having ethical concerns, because to do so was tantamount to admitting that there really was something morally wrong with animal experimentation, thereby giving "ammunition to the enemy."(167) Animal researchers' ethical defense of the practice has been superficial and self-serving. Usually, they simply point to supposed human benefits and argue that the ends justify the means.(168,169) Often, they add that nonhuman animals are "inferior," lacking certain attributes compared to humans, such as intelligence, family structure, social bonding, communication skills, and altruism. However, numerous nonhuman animals - among them rats, pigs, dogs, monkeys, and great apes - reason and/or display altruism. There is accumulating evidence that many animals experience the same range of emotions as humans.(170,171) Chimpanzees and gorillas can be taught human sign language, and sign with one another even without humans present.(172,173) The general public, which cares about animal welfare, has been led to believe that animals rarely suffer in laboratories. Animal researchers often cite U.S. Department of Agriculture (USDA) statistics (derived from researchers themselves) that only 6 to 8 percent of animals used in vivisection experience pain unrelieved by anesthesia or analgesia.(174) Evidence indicates, however, that many animal researchers fail to acknowledge - or even perceive - animal pain and suffering. For example, sociologist Mary Phillips observed animal researchers kill rats in acute toxicity tests, induce cancer in rodents, subject animals to major surgery with no post-operative analgesia, and perform numerous other painful procedures without administering anesthesia or analgesia to the animals. Nevertheless, in their annual reports to the USDA, none of the researchers acknowledged that any animals had experienced unrelieved pain or distress. Phillips reported, "Over and over, researchers assured me that in their laboratories, animals were never hurt...'Pain' meant the acute pain of surgery on conscious animals, and almost nothing else...[When I asked] about psychological or emotional suffering, many researchers were at a loss to answer."(175) The tens of millions of animals used and killed each year in American laboratories generally suffer enormously, often from fear and physical pain, nearly always from the deprivation inflicted by their confinement, which denies their most basic psychological and physical needs.Conclusion The value of animal experimentation has been grossly exaggerated by those with a vested economic interest in its preservation. Because animal experimentation focuses on artificially created pathology, involves confounding variables, and is undermined by differences in human and nonhuman anatomy, physiology, and pathology, it is an inherently unsound method to investigate human disease processes. Billions of dollars invested annually in animal research would be put to much more efficient, effective, and humane use if redirected to clinical and epidemiological research and public health programs.

Anouk Sickler Dec 29, 2004 6:49 PM advice on what to say. hi, I am seeking advice, same old question, someone at work, after finding out that I was vegan, ask me that if It weren't for animal testing, many of us wouldn't be here. Animal testing has extended many of our lives, and If my son was dying, and I knew that a drug that had been tested on animals would save his life, for sure that I would give it to him. I really didn't know what to answer. without sounding stupid.what would've you guys have said?ThanksanoukTo send an email to - Quote Link to comment Share on other sites More sharing options...

There are so many good answers: 1. Over 75% of drugs considered safe after testing on animals are withdrawn from sale within five years due to harmful side-effects on humans. 2. Over 45% of people in hospital are there because of side-effects from drugs considered safe after animal testing. 3. Animal testing is not reliable, and is flawed in its basic premise since results from one species can never be successfully extrapolated to another. This method of testing drugs is promoted because it is a big money- maker for suppliers of the animals, and has held back medical science considerably. If we dispense with animal testing, and move over to computer simulation, cell culture tests and human volunteers, we will make many more medical advances much more rapidly. 4. Ask when he will be taking his next dose of DDT. 5. (My personal favourite) Ask him if he ever uses a computer... then ask him if he thinks it's OK to exterminate Jews. Assuming he answers the same way as 99% of the population, point out to him that the entire basis of modern computing comes from the IBM systems created for administering the death chambers at Auschwitz, and ask him if he will now throw away his computer. Then ask him if he will use any of the medicines which were tested in nazi concentration camps. Point out that results from one human subject can be extrapolated to another, and therefore at least the methods used in Nazi Germany were scientifically supportable, unlike animal testing. 6. The past can't be changed... animals that have been killed can't be brought back to life. No further harm is done by taking the medicines concerned, and while you are alive you can continue to fight to get rid of animal testing which would benefit both humans and animals... if you choose not to take the drug and die, then you can't do any good for anyone. 7. If all else fails, just point out that he's an idiot, and ask him what he does to attempt to prevent animal or human suffering, or whether he just tries to pick fault with those who do try to make a difference to make himself feel better about his own lack of action.

I am so glad I joined this club. Never know when I will have to talk against animal testing. Vijay Quote Link to comment Share on other sites More sharing options...
