ABSTRACT : This paper presents a comparative research on regulation, which moves from international research ethics framework, by analysing CIOMS International Ethical Guidesfor Health-Related Research with Human Beings and goes to national and institutional regulation of human research in Costa Rica, searching for bioethical foundations, such as human respect, justice, and beneficence. Characterizing each one, and analysing each regulation, to see whether national and institutional articles, still have bioethical contents, and if so, how is it presented. Ultimately, the paper argues for the promotion of justice on regulations, to give protection of the rights and well being of vulnerable people, give an appropriate response, secure a reasonable availability and compensation for damages.
