[Social and ethical issues of xenotransplantation].
The worldwide shortage in the supply of donor organs and tissues is becoming more pronounced. Xenotransplantation may probably give the hope to overcome the problem ultimately. However, it gives rise to a number of social and ethical issues, among them, the pig appears to be a likely source for human transplantation because it entails least social and ethical issues than no-human primates or other animals and the pig is similar to human in many aspects. The ethical and economic aspects must also be taken into consideration. Patient and his family's privacy may be stripped because the patient has received a new or unusual treatment. Xenograftings will squint towards a kind of commodities which are different from human graftings and it is a challenge to human transplantation. Xenotransplantation brings a risk of creating new human disease and pandemic, so, it is necessary to formulate a policy and provide input to draft guidelines on the regulation of xenotransplantation.
