甲状旁腺高血压因子与原发性高血压的关系

THE RELATIONSHIP BETWEEN PARATHYROID HYPERTENSIVE FACTOR AND ES-SENTIAL HYPERTENSION

探讨153例原发性高血压患者血浆中甲状旁腺高血压因子(PHF)对正常大鼠的升压作用,并测定了血浆中的甲状旁腺素(PTH)水平.结果表明61例血浆PHF可使正常大鼠的血压产生延迟性升高,在注射后10分钟开始有反应,50分钟达高峰,70分钟恢复到注射前血压水平;另92例血浆未能产生升压效应.153例血浆PTH水平远高于正常对照组,有PHF组和无PHF组间无明显差异,但与正常组比较差异均有显著性,提示升高血压不依赖于PTH,而是通过PHF起作用.

The effect of plasma parathyroid hypertensive factor (PHF)from 153 essential hypertensive subjects on pressor response in normotensive rats was evaluated and plasma levels of parathyroid hormone (PTH) in these patients were measured. The results showed that PHF from 61 patients could induce a delayed increase in blood pressure in the normotensive rats. Mean arterial pressure (MAP) began to increase at 10 minutes after injection and a peak response was reached at 50 minutes while pre-injection MAP level was recovered at 70 minutes. On the other hand, plasma PHF in remaining 92 patients failed to induce a pressor effect. Plasma PTH in the 153 patients were considerably higher than those of the control, and the plasma PTH from the two groups, either with or without PHF, showed significant difference in comparison with the control, but plasma PTH between these two groups did not show significant difference. The results have suggested that pressor effect was independent of PTH but depends on PHF.
