From the University of Chicago, came tidings of additional experiments in transplantation by Doctor Theodore Koppanyi, already mentioned in these columns for his work on transplanting the eye and the spleen...
...Koppanyi has tunneled a passage in the skull of a fish, and removed one eye with its nerve into this passage, so that the eye, instead of projecting to the side, looks directly upward, the remaining eye being blinded. When the eye is thus transplanted, the fish turns and swims on his side instead of in the usual upright posture. These experiments indicate that the eye has a definite function in maintaining the equilibrium of the body. It has heretofore been generally believed that the function of balance was maintained primarily by the semicircular canals which form a part...
Theodor K o p p a n y i, experimental physiologist in the University of Chicago, has just made public the results of attempts to transplant the mysterious organ known as the spleen from one animal to another. The name of Koppanyi is familiar because of his attempts at transplanting a human eye (TIME, June 18, 1923, Oct. 20), which have apparently been successful thus far to a very limited extent, only in the case of rats. His new experiments indicate that the spleen can be transplanted in the case of certain lower forms of animal life, and perhaps...
Prof. A. J. Carlson, of the Department of Physiology in the University of Chicago, replied (Oct. 11) to Prof. Imre's attack on Dr. Koppanyi, testified as to the scientific status of Dr. Koppanyi's work. Prof. Carlson pointed out that Dr. Koppanyi has been on the research staff of his laboratory in the University of Chicago since January, and that such newspaper stories as have appeared have not been authorized either by Dr. Koppanyi or by the laboratory. Experiments have been made on spotted rats; and the transplanted eyes have undergone varying degrees of change from complete...
Supplementing the letter of Prof. Carlson, Dr. Koppanyi declared (Oct. 11) that the charges of Prof. Imre are not true. He denied that he gave unwarranted publicity to his work. He said that the return of vision is possible, but admitted that the optic nerve was not cut in his eye transplantation experiments...
