During this same span of time, humans came to be the subjects of research in many countries throughout the world in areas of basic and applied research, including both biomedical and social/behavioral studies. The research related to development of new medical products, improved surgical and medical procedures, and enhancements to our knowledge of physiology, biochemistry, pharmacology, behavior, and many other areas of science and medicine. There are numerous examples that involve abuse of humans through failure to disclose the purpose of the studies, failure to inform subjects of risks, coercion, undisclosed personal gain by researchers, unethical intentions of nations, and many other situations that are frequently cited as atrocities committed against humans.
Research conducted on humans by Nazi physicians during World War II led to the formulation of a code for human subjects research known as the Nuremberg Code (1947). While not enforceable as law, the Code and later the Declaration of Helsinki (1964, latest revision in 2004) provided the first international guidelines for the ethical treatment of human subjects in research.
Unethical research continued, however, as U.S. researchers tested the effects of radiation on hospital patients, children, and soldiers without obtaining consent or permission. In a study widely known as the Tuskegee syphilis study, conducted by the U.S. Public Health Service on African American males, the course of the untreated disease was tracked over several decades, well after antibiotics were discovered that were effective in treating the disease. Several unethical studies involved children, such as one conducted at New York's Willowbrook State School (1956 to 1972) where researchers infected children with a mild form of hepatitis to study the natural history and prevention of viral hepatitis.
These and many other studies raised questions about the ethics of involving humans as subjects of research. As a result, Congress created a National Commission for the Protection of Human Subjects of Biomedical and Behavioral Research in 1974. Over the next four years, the National Commission issued several reports, including the report widely know as the Belmont Report: Ethical Principles and Guidelines for the Protection of Human Subjects. These reports eventually became the basis of U.S. regulations for the protection of humans involved in research, including vulnerable groups of subjects such as pregnant women, fetuses, neonates, children, and prisoners. In 1991, many federal agencies that conduct or support research involving human subjects adopted the Federal Policy for the Protection of Human Subjects, known as the "Common Rule" (45 CFR 46, Subpart A). Additional regulations and numerous guidances have been issued since then, providing a foundation for protections of human subjects of domestic and international research. The authority for enforcing the regulations of the Department of Health and Human Services (DHHS) for protection of human subjects involved in research conducted or supported by HHS has been delegated to the Office for Human Research Protections (OHRP) within the Office of Public Health and Science, Office of the Secretary, DHHS.
Research that is conducted or supported by agencies outside of HHS may also come under the purview of the HHS regulations if the institution conducting the research has agreed to comply with the HHS regulations, regardless of the source of funding, through the required Federal Wide Assurance, Multiple Project Assurance, or other assurance agreement. Having an assurance agreement with OHRP is a condition of receiving HHS funds for research involving humans. Thus, research involving humans may be unregulated, one extreme, may be regulated by the funding agency, such as HHS, or may be regulated by multiple agencies in the other extreme.

SOT INVOLVEMENT IN HUMAN RESEARCH |

The SOT has also posted several position statements on its Web site, www.toxicology.org. "Use of Animals in Toxicology" was added to the Web site in January, 1986. Two additional statements were posted in March, 1999: "Animals in Research Public Policy Statement" and "Guiding Principles in the Use of Animals in Toxicology."

HUMAN RESEARCH POLICIES |

The vulnerability of medical journals from publication of study or trial results that could subsequently be found to involve some unethical practice has driven those journals to require authors to certify that they have complied with all applicable regulations. Because any journal of the SOT is similarly vulnerable, it is appropriate that the Society has now expanded the instructions for authors to cover studies that involve research in humans.
What are the regulatory authorities of federal agencies to oversee protection of human subjects of research, and how do they relate to the new policies of the SOT? As mentioned earlier, many federal agencies have adopted the "Common Rule." The codification for each agency is shown in Table 1. While all of these agencies/departments have adopted Subpart A, the part of the regulation known as the "Common Rule," not all agencies/departments have adopted the other subparts: Subpart BAdditional Protections for Pregnant Women, Human Fetuses and Neonates Involved in Research, Subpart CAdditional Protections Pertaining to Biomedical and Behavioral Research Involving Prisoners as Subjects, and Subpart DAdditional Protections for Children Involved as Subjects in Research.

If the activity under consideration is research, is research involving humans, and is not exempt, the regulations apply. The protocol must be reviewed and approved by an IRB; the IRB composition and procedures are defined by the regulations, as are the requirements for informed consent and annual continuing review.

CONCLUSIONS ON A SOT POLICY FOR HUMAN RESEARCH |

The toxicology community has long recognized that observations in humans are a critical part of the knowledge base of the field of toxicology. As with research involving various species of laboratory animals, research studies and clinical trials involving humans as subjects are critical to new product development, development of new medical and clinical procedures, as well as new occupational and environmental standards of exposure. Public trust is a requisite for continuation of the right to conduct research in the future that involves laboratory animals or humans. Unethical behavior of any member of the SOT or by authors of papers published in a journal of the Society could seriously jeopardize the credibility of toxicologists and the SOT and thereby undermine the trust of the public in this field of science. A human research policy will go a long way in helping to prevent unethical behavior in research by members of the SOT.
