This concern has led to laws and regulations administration the use of animals in interrogation and to various guides and statements of principle intentional to ensure clement treatment and use of laboratory animals.

In 1628, William Harvey published his pop off on the heart and the movement of blood in animals (French, 1975).

In the 18OOs, when France became unitary of the leading centers of observational biology and medicine-marked by the get of such( prenominal) scientists as Francis Magendie i! n experimental physiology, Claude Bernard in experimental medicine, and Louis Pasteur in microbiology and immunology-investigators regularly used animals in biomedical research (McGrew, 1985). Research in biology progressed at an increasing pace first around 1850, with many of the advances resulting from experiments involving animals. Helmholtz studied the physical and chemical activities associated with the reflexion impulse; Virchow developed the science...
