The ultrastructure of the parathyroid glands of hypophysectomized golden hamsters was studied. In the parathyroid glands of hypophysectomized animals the Golgi complexes and secretory granules were significantly decreased and large vacuolar bodies were significantly increased compared with those of the control animals. In addition, the chief cells contained a few prosecretory granules in the Golgi areas and a few secretory granules were present in the peripheral cytoplasm. These results suggest that the synthesis and release of parathyroid hormone may be suppressed in the parathyroid glands of the hypophysectomized animals.
对垂体切除的金黄仓鼠甲状旁腺的超微结构进行了研究。与对照动物相比，垂体切除动物的甲状旁腺中，高尔基体复合物和分泌颗粒显著减少，大的空泡体显著增加。此外，主细胞在高尔基体区域含有少量前分泌颗粒，外周细胞质中存在少量分泌颗粒。这些结果表明，垂体切除动物的甲状旁腺中甲状旁腺激素的合成和释放可能受到抑制。
