Transplant fails

PITTSBURGH (AP) - A man who received a baboon's liver in the first such animal-to-human transplant died late on Sunday. Doctors at the University of Pittsburgh Medical Center were trying to wean the 35-year-old man from a respirator on Sunday afternoon when they discovered his brain was bleeding. He suffered a stroke and was pronounced dead nearly seven hours later.

Doctors did not yet know what had caused the bleeding, said a member of the transplant team. The man, whose name has been withheld at his request, received the baboon's liver during an 11- hour operation on 28 June.
