Some doctors and scientists believe animal testing is not the best method for medical advances for many reasons and examples. In multiple cases, certain drugs have proven effective on animals but are not effective on humans. This occurs most often when testing drugs for stroke. Others include the following examples: a therapeutic dose of aspirin in a human is poisonous, but it has no negative effects to different animals; benzene causes leukemia in humans but not in mice; insulin produces birth defects in humans but not in animals; morphine calms people but excites some animals; chloramphenicol produces aplastic anemia in some humans but saves animals; fenclozic acid causes liver toxicity in people but not in some animals; penicillin is highly poisonous to a few animals but helps humans (Gorman 49).
Other than examples of failures resulting from animal testing, there are other reasons doctors and scientists believe it is not effective. One of which being animals and humans have different genetic makeup. This means, because of the different DNA structures, some diseases are difficult to induce in animals since it does not naturally …show more content…
Studies aided by animals are helping scientist develop new therapies for premature babies to help their lungs and air-flow. Animal testing has aided in helping increases the amount of surviving children suffering from leukemia from four to eighty percent in the last fifty-three years. Another major discovery currently giving people real, growing, and fast hope is new treatments being discovered, by scientists and physicians at Duke University, to treat glioblastoma multiforme (GBM). Just months ago patients with GBM, who had little hope of surviving, now have a realistic chance of living a long, pain-free life. Just like those affected by GBM, millions of others affected with cancer, a disease, and/or broken bones all have the chance of researchers and scientists developing new procedures or medicine to give them a fighting chance. But, most of these developing procedures and medicines could be developed through an
