【Abstract】ObjectiveTo investigate the technique of establishing a model of aparathyroid rat which could be used in the study of parathyroid cells transplantation. Methods Parathyroid glands were surgically excised and identified pathologyically. Serum calcium and parathyroid hormone in rats before operation and on day 2，5，10，15 and 30 after operation were measured. Results Parathyroid glands were resected successfully in 8 rats, and the resection rate was 80% (8/10). No obvious changes of serum calcium and parathyroid hormone levels were found before and after operatiion in sham parathyroid gland excision group (Pgt;0.05). However, statistically significant changes of those data were found perioperatively in parathyroid gland excision group (P＜0.01). Conclusion The model of aparathyroid rat can be established successfully after parathyroid glands in rats are excised exactly. Parathyroid allotransplantation could be performed ten days after parathyriodectomy.
