["Population and xenograft" investigation. Preliminary results].

The chronic shortage of human organs is the argument for xenotransplantation. In emergencies, acceptability is closely linked to the benefit. Little information is available on attitudes towards xenotransplantation. A poll of the attitudes was carried out, based on a questionnaire with targeted questions and background information. The goal of the study was to have a better understanding of people's attitudes towards xenotransplantation and to know the eventual changes in the answers after having been given information. For 75% of the sample, xenotransplantation would be a future biotechnology. The animal sources that would be considered for xenotransplantation were the pig and monkey. A period of ten years or more is necessary for 69% of the respondents before xenografts are performed routinely; for 19%, five years or less are needed. Human organ donation should be continued, according to 90% of the sample. Roughly, 46.4% support xenotransplantation, though in the case of a life-or-death situation acceptance reaches 65.7%. This level is higher (77%) for relatives or unknown people (71%); 74% of respondents were in favour of using normal animals and a large majority (88%) support research on xenotransplantation. A good level of confidence in medical biotechnology research and practice is suggested by this study, contrary to the results of a European survey on biotechnology.
