Having under our care a large number of cretins in whom cessation of the thyroid feeding leads rapidly to a recurrence of myxedema with its train of symptoms, we were led to undertake the following experimental work on autotransplantation and homotransplantation of the thyroid gland in the hope of obtaining sufficient positive results to warrant clinical operative interference. The following experimental operations are presented as a preliminary report.
AUTOTRANSPLANTATION
We have found that the autotransplants of the thyroid gland into the thyroid capsule was successful in all our cases, corroborating the work of other investigators in autotransplantation.We have studied three such cases of multiple autotransplantation.
HOMOTRANSPLANTATION
The homotransplantation of the thyroid gland in animals is of great importance, and yet it has been unsuccessful up to the present time. Success in this form of transplant work would be a great step in solving the question of
