Introduction

Scientists use laboratory animals to investigate biological processes in humans. Animals are used to study the causes of disease, to test drugs, vaccines and surgical techniques. They have also been used to evaluate the safety of some chemicals used in pesticides, cosmetics and other products.

Scientific and biomedical research can be done with laboratory cultures of specific cells or tissues. They are used with simple life forms like bacteria. However, some studies reach more satisfactory results through the study of more complex responses of an animal. Many animals function as human beings that is why they provide good models for experiments in fundamental processes such as respiration, ingestion, digestion of food, and reproduction. Some animals suffer the same diseases as humans and their immune systems respond similarly to disease causing agents such as viruses or bacteria. Animals have many genes identical to those of humans. In light of this, by studying animals, scientists have been able to learn much about the human body.

Discussion

Aristondo argued that in any human-animal relationship, the well-being of humans as the animals are relevant. However animals can be sacrificed for important human needs, including the progress of clinical medicine. Humans can be considered as managing the use of animals with the responsibility to use animals for purposes that serve the best interests of humans while ensuring that animals are treated well everywhere ( home, farm, laboratory).

The contemporary Jewish teaching suggests that the relief of human suffering takes precedence over considerations of animal welfare. Judaism teaches that animals were created to serve mankind. Hence their use as food, pack animal and pet is allowed. The only restriction being to treat animals in a way that takes into account their pain and suffering possible. If we accept this position, you might consider immoral does not conduct clinical research requiring the use of animals, because "saving" these animals, the clinical benefit potentially significant to humans is lost. There is no morality in the act of "saving" animals use in clinical research unless the research methods can not reduce the pain and discomfort of the animal and the potential benefits for society as a whole are not predictable (Meredith, 2010).

About 30% of all animals go to basic research. Many processes, the function of different structures and the extreme complexity of the whole are still beyond our comprehension. Some specific processes involved in a living organism can indeed be studied in isolation. But only in a living animal that can study the specific interactions between particular organs, cells and cell components. The comparison test between several animal species often leads to entirely new knowledge. Basic research also depends on animal experiments. We often forget that basic research is the basis of applied medical research tomorrow. On the other hand, applied research is also born of new issues within basic research. In other words: basic research and applied research are interdependent and lead to advances in medical practice.

All medical research do not produce products or technologies beneficial. Some experiments produce data that are inconclusive ...
