The effects of hypocalcemic and hypercalcemic substance on activity of the parathyroid and plasma calcium and phosphorus levels in the lizard, Uromastix hardwickii are described. The cellular hypertrophy and degranulation of cytoplasm in the parathyroid cells along with decrease in plasma calcium level appeared after sodium citrate and ethylenediaminetetraacetate (EDTA) treatment. On the other hand, degenerative changes are observed after calcium chloride treatment. It is suggested that the secretion of parathyroid is regulated by the circulating blood calcium level.
描述了低钙血症和高钙血症物质对蜥蜴硬尾蜥甲状旁腺活性以及血浆钙和磷水平的影响。柠檬酸钠和乙二胺四乙酸(EDTA)处理后,甲状旁腺细胞出现细胞肥大和细胞质脱颗粒,同时血浆钙水平降低。另一方面,氯化钙处理后观察到退行性变化。提示甲状旁腺的分泌受循环血钙水平的调节。
