人红细胞(RBC)是甲状旁腺激素(PTH)的靶器官,该激素增加红细胞渗透脆弱性并诱导其溶血。本研究旨在探讨血中PTH水平升高是否会影响红细胞存活,以及PTH作为一种红细胞外因子是否与慢性肾衰竭患者红细胞存活缩短有关。在6只正常犬、6只慢性肾衰竭和继发性甲状旁腺功能亢进(NPX)犬以及6只慢性肾衰竭程度和持续时间相当的甲状旁腺切除犬(NPX- tptx)中,51cr标记的红细胞存活率升高。正常犬51cr标记红细胞存活时间为22 ~ 35 (25.6 +/- 1.9)d, NPX犬51cr标记红细胞存活时间缩短,为16 ~ 20 (18.4 +/- 0.6)d,显著低于正常犬(P < 0.01)。在NPX- tptx犬中,51cr标记的红细胞存活时间在20 - 33 (25.2 +/- 1.8)d之间,与正常犬无显著差异,但显著高于NPX犬(P < 0.01)。我们的数据表明,血液中PTH水平过高,而不是尿毒症状态的其他后果,是慢性肾衰竭患者红细胞存活时间缩短的原因。
The human erythrocyte (RBC) is a target organ for parathyroid hormone (PTH) and the hormone increases RBC osmotic fragility and induces their hemolysis. The present study was undertaken to examine whether elevated blood levels of PTH affect RBC survival, and therefore whether PTH, being an extracorpuscular factor, is responsible for the shortened RBC survival in chronic renal failure. 51Cr-labeled RBC survival was elevated in six normal dogs, in six animals with chronic renal failure and secondary hyperparathyroidism (NPX), and in six thyroparathyroidectomized dogs (NPX-TPTX) with comparable degree and duration of chronic renal failure. In the normal dogs, 51Cr-labeled RBC survival ranged between 22 and 35 (25.6 +/- 1.9) d. In the NPX dogs, 51Cr-labeled RBC survival was shortened and the values ranged between 16 and 20 (18.4 +/- 0.6) d, a value significantly (P less than 0.01) lower than normal dogs. In NPX-TPTX dogs, 51Cr-labeled RBC survival ranged between 20 and 33 (25.2 +/- 1.8) d, a value not different from that in normal dogs but significantly higher (P less than 0.01) than that in NPX animals. Our data demonstrate that excess blood levels of PTH and not other consequences of the uremic state are responsible for the shortened RBC survival in chronic renal failure.
