把血钙正常的原发性甲状旁腺机能亢进定为一种综合征,其特征是经反复证实血清钙、磷含量正常的受检者伴有复发的肾结石,手术时大体和微观可见到异常的甲状旁腺Johannson 等研究了84名受检者,发现19例患甲状旁腺腺瘤,39例增生和26例甲状旁腺正常。但就其中29例(35%)观察,血清钙浓度有时为5.3～5.5mEq/L(正常范围应是4.4～5.2mEq/L)。因他们存在功能亢进的甲状旁腺,故比血钙正常的甲状旁腺机能亢进者更可能有轻度间歇性的高钙血症。行甲状旁腺切除术后的19例腺瘤患者未再出 The normal primary hyperparathyroidism as a syndrome of hyperparathyroidism, characterized by repeated tests confirmed that serum calcium and phosphorus were normal subjects with recurrent renal stones, the general and microscopic surgery can be seen Abnormal parathyroid Johannson et al. Studied 84 subjects and found that 19 had parathyroid adenoma, 39 had hyperplasia, and 26 had normal parathyroid. However, in 29 cases (35%), the serum calcium concentration was sometimes 5.3-5.5 mEq / L (the normal range should be 4.4-5.2 mEq / L). Because they have hyperparathyroidism, they are more likely to have mild intermittent hypercalcaemia than hyperparathyroidism. 19 cases of adenoma after parathyroidectomy patients did not go out
