...nucleus of one amoeba with a microprobe and sucked out most of the cell's cytoplasm with a tiny pipette. Then they inserted into the remaining cell membrane a nucleus and cytoplasm that had been similarly removed from other cells. In more than 70% of their attempts, the transplant produced a completely viable new cellas long as the components used were taken from amoebae of the same strain. But when they tried the same reshuffling with parts from amoebae of different strains, the experiment failed in all but two of 434 tries...
Although harvesting and storing eardrum tissue is no longer difficult, the transplant procedure remains delicate. Surgeons make an incision behind the recipient's ear and cut away any diseased or damaged portions of the hearing organs before replacing them with the donor tissue.,If only the donor's eardrum is used, it is fastened to the patient's ossicles with a nylon sling. If the donor's ossicles are used as well, they are connected to the patient's remaining ear bones so that sound vibrations can be conducted unimpeded to the inner...
Tissue rejection, which has led to the failure of other transplant operations, has yet to prove a problem in eardrum homografts. Nor have other complications arisen. Doctors across the country have performed about 70 such operations since 1968. Perkins, who has done 30 of them, reports that 90% of the new eardrums are still in place and intact...
...massive overstatement. They offer nothing more than a two-hour supply of mouth froth, a dentifrice rather than a drama. Vonnegut's cute conceit has been to debunk the Ulysses myth in terms of the Hemingway legend. As Vonnegut sees it, war is a kind of priapic transplant for men whose sexual insecurity demands the bolstering arsenal of the sword, the gun, the hunt and the kill. As amateur psychologizing, that may be perfectly acceptable; as drama, it turns out to be perfectly dreadful...
Russian doctors are generally wary of heart transplants. Only one such operation has been attempted in the Soviet Union. The operation was unsuccessful and Petrovsky frankly questions its value. "We are doing experimental work on heart transplantation," he says. "But we do not believe that this problem is as important as kidney transplantation. In the latter case we operate when the kidneys cease to function, and the patient cannot live any longer with these kidneys." Soviet medical men have no such reservations about bone transplants, which are now being done regularly at Moscow's Institute of Traumatology. In Soviet...
