For centuries, many cultures have described mythical creatures with bo
dies that combined human and animal features, often the result of viol
ating taboos. This study attempted to investigate the beliefs of trans
plant patients about xenografting. A survey was given to 100 patients
ranging in age from 17 to 74 years old with 65 men and 35 women, inclu
ding 72 whites, 18 Hispanics, 5 African Americans, and 4 Asian America
ns. The subjects included liver; heart, kidney, lung, and multi-organ
transplant patients. The patients were not aware of plans for xenograf
ting at the center under study. Eighty patients agreed with xenografti
ng in an emergency situation. Ten subjects replied, ''under no circums
tances.'' Ninety pet-cent believed animal research has advanced medica
l science. In descending order the patients preferred human (96%), mon
key (44%), mechanical (43%), pig (42%), or dog (34%) organs. Twenty-fo
ur patients thought a xenograft would change their appearance, persona
lity or eating or sexual habits. Twenty patients believed animals have
souls. The patients also documented any ethical concerns about xenogr
afting.
