[Parathyroid transplants in dogs]

Autotransplantation of the parathyroid glands by mincing method has been performed to maintain parathyroidal function in patients with thyroid cancer, following total thyroidectomy and parathyroidectomy. The functional recovery of grafted parathyroid glands was studied in matured mongrel dogs histologically and by determining the PTH level and serum P, Ca, and compared three different forms of implant; whole gland, minced parathyroid tissue, and thick slices. The minced parathyroid tissue and thick slices were found to be far superior histologically, and endocrinologically, to the whole gland type of implant, with successful takes. And between two types of implants minced tissue and thick slices, no difference was observed histologically and endocrinologically. On the other hand, it is necessary for shortening the time to prepare implant tissue to get successful reimplantation. The time to prepare minced tissue is very short in comparison with thick slices. Thus our method (minced tissue) is very useful for successful reimplantation of the parathyroids.
