The Tuskegee Syphilis Study was originally conceived in 1929 by the United States Public Health Service (USPHS) as a method of determining the prevalence of syphilis within communities black women across America and to identify mass treatment. The reason for this segregation was that doctors believed that both whites and blacks were opposites and reacted differently to diseases. Furthermore, syphilis and other widespread venereal diseases were widely believed to be responsible for the high crime and abortion rates in African American townships, and until now no effective cure had been discovered. As a result, approximately 600 male subjects were recruited from the town of Tuskegee in Macon County, Alabama. Although the ethicality of the experiment could be argued at first, by the time it formally began in 1932, the scope had changed significantly. Dr. Taliaferro, then chief of the USPHS's venereal disease division, stated that the procedure now involved observing subjects while at the same time telling them that they had "bad blood" and would receive free treatment. About two decades after the study began, penicillin became widely available and proved to be an effective treatment for many diseases, including syphilis. However, the USPHS made many efforts to prevent study subjects from being treated by other organizations. In 1972, Peter Buxton, a USPHS employee who had challenged the moral basis of the case six years earlier, denounced and ended the study when he leaked the story to a local reporter. Although records maintained by the USPHS regarding the Tuskegee syphilis study were substandard, it is believed that between twenty-eight and… half of the paper… humane society benefits and burdens of research involving human subjects. In particular, participants chosen for such research should not be selected unfairly from groups unlikely to benefit from the work. This point alludes to discrimination and states that medical research should include an equal number of subjects of different genders, races, ages and backgrounds. in order to improve the human race as a whole. By implementing these parameters in biomedical research, organizations can improve civilization, doing so in an ethical manner. The Tuskegee syphilis study raised numerous questions and concerns regarding regulation within professional activities. Doctors and physicians take the Hippocratic Oath and vow to help those around them. This experiment demonstrated why rigorous ethical and control measures are necessary when people's lives are at stake.
