[Bioethical reflections: necessity to promote altruistic attitudes toward medical research in human beings].

In this paper some bioethical reflections about medical research in human beings are made. The social moral obligation to increase this kind of investigation, with the purpose of enlarging resources to take care of the health of society, as well as to comply with the moral duty of keeping the integrity of the participating subjects, have placed to medical investigators face to face with ethical problems that may affect the development of this essential activity for human healthcare. On one hand, in the present context, the resistance of both healthy and sick individuals to collaborate in the studies, as possible, according to a wrong autonomous decision (irreflexive individualism). On the other hand, the shortage of anticipating strategies that promotes altruistic attitudes to take into account, the suffering experiences proper of human nature. In this regard, the author focuses his reflections, from the principle of social welfare that underlies medical research and of the necessity of providing instrumentation for some educational policy that without lacking respect for the autonomy of subjects, would propitiate the participation of society so that humanity would continue to benefit from the achievements of this type of research.
