Abstract
The lateral parathyroid gland of the rabbit was resected and autotransplanted under an ear skin flap. A skin flap at the opposite side was used as control. The success of autotransplantation was established by microangiography of the transplant and by measuring plasma concentrations of parathyroid hormone (PTH), calcium and phosphorus. After 4 months the animals were killed and the transplant was studied histologically and by electron microscopy. Fourteen animals were included in the study. There was an increase in PTH derived from the transplanted gland after 4–6 postoperative days. All animals developed hypocalcaemia during the 3 days after transplantation. There were no significant changes in serum phosphorus. Transplantation did not alter the morphology of the distribution of the cells in the transplanted gland, which functioned normally after the fourth postoperative day.
