An analysis of medical experiments in animals

Additionally, well designed studies and appropriate statistical analysis of data can minimize the number of animals required for statistically significant results.

Animals in Experiments

Chemicals tested on the U. Sweet, who died inmaintained that consent had been obtained from the patients and next of kin. Some knowledge of statistics is assumed because most scientists will have had some training in this discipline. John P Gluck has suggested that this is often lacking: Years after these experiments, more than 1, of these soldiers suffered from several illnesses, including depression and epilepsy.

Slightly larger ones can provide estimates of the means and standard deviations and possibly also some indication of likely response, which can be used in a power analysis to determine sample sizes of future experiments see below.

It causes death by a concussion to the brain. All of the subjects became sick and 13 died. Another principle is to reduce animal use as far as possible in any given study.

For example, many microarray experiments in which up or down regulation of many thousands of genes is assayed in each animal could be classified as exploratory experiments because the main purpose is usually to look for patterns of response rather than to test some prespecified hypotheses. Pilot Studies Pilot studies, sometimes involving only a single animal, can be used to test the logistics of a proposed experiment.

The human moral community, for instance, is often characterized by a capacity to manipulate abstract concepts and by personal autonomy. Human radiation experiments Researchers in the United States have performed thousands of human radiation experiments to determine the effects of atomic radiation and radioactive contamination on the human body, generally on people who were poor, sick, or powerless.

Some of the chemicals tested on human subjects included mescaline and the anticholinergic drug scopolamine. Animal experiments only benefit human beings if their results are valid and can be applied to human beings.

At the onset of sleep, the rat would either fall into the water only to clamber back to the pot to avoid drowning, or its nose would become submerged into the water shocking it back to an awakened state. Ethical Considerations The use of animals in scientific experiments likely to cause pain, distress, or lasting harm generates important ethical issues.

Similarly, the experimental material may have some natural structure e. It is helpful to readers to number the experiments. Investigators are urged to consult a statistician at the design stage and are reminded that no experiment should ever be started without a clear idea of how the resulting data are to be analyzed.

It may save you much trouble if you publish your paper Drug B killed all the dogs and rats. Below, I will outline one of the more common arguments used to reach this conclusion. Formal Experimental Designs Several formal experimental designs are described in the literature, and most experiments should use one of these designs.

Failure of these controls to respond might imply, for example, that some of the apparatus was not working correctly. Recommended methods include decapitation beheading for small rodents or rabbits.

When there are several correlated outcomes e.

Experimenting on animals

In the United States and China, most primates are domestically purpose-bred, whereas in Europe the majority are imported purpose-bred. He did this without the consent of the patients, and without informing them of what he was doing. The strongest pro animal rights answer to this question would be that non-human animals have exactly the same moral status as humans and are entitled to equal treatment.

Thus, if there are six different treatments, a block will consist of a multiple of six animals that have been assigned at random to each of the treatments. The thinking, feeling animals who are used in experiments are treated like nothing more than disposable laboratory equipment.

Staff should be well trained, and housing should be of a high standard with appropriate environmental enrichment. Rowe had authorized him to administer.

Most statistical packages for computers will produce random numbers within a specified range, which can be used in assigning experimental units to treatments.

When appropriate, anesthesia should be used; additionally, studies should have the earliest possible endpoints after which animals who will subsequently experience disease or suffering can be euthanized.

In summary, defenders of animal experimentation argue that humans have higher moral status than animals and fundamental rights that animals lack. In another study, they gave 25 newborn babies who were under 36 hours old and weighed from 5.

Black inoculated a twelve-month-old baby with herpes who was "offered as a volunteer". What You Can Do Tell research-funding agencies to kick their animal experimentation habit. Within each type of design there is considerable flexibility in terms of choice of treatments and experimental conditions; however, standardized methods of statistical analysis are usually available.The Validity of Animal Experiments in Medical Research Gill Langley Dr Hadwen Trust for Humane Research, Langley, G.

(). The validity of animal experiments in medical research. RSDA, 1, 1 Langley, Gill (). that some experiments on animals may suggest some useful hypotheses about human medical conditions.

Essay about Medical Experiments on Animals Create Abuse and Suffering Words | 7 Pages. Creams: An Analysis of Vivisection in the Medical Industry million animals are killed every year due to different experiments being tested on the animals.

Many medical research institutions make use of non-human animals as test subjects.

Animal testing

Animals may be subject to experimentation or modified into conditions useful for gaining knowledge about human disease or for testing potential human treatments. Design and Analysis of Experiments in the Animal and Medical Sciences. Volume 1, Volume 2, and Volume 3 (Appendices).
