本实验采用同位素８６Ｒｂ代替Ｋ＋，测定３７例原发性高血压（ＥＨ）病人红细胞的８６Ｒｂ主动摄取率。发现青年ＥＨ组病人８６Ｒｂ摄取率（７．３３ｎｍｏｌ／ｍｌ细胞·分－１）较对照组（４．２８ｎｍｏｌＲｂ／ｍｌ细胞·分－１）增高（Ｐ＜０．０５），而高年龄ＥＨ组病人（４．１６ｎｍｏｌＲｂ／ｍｌ细胞·分－１）较对照组（５．９０ｎｍｏｌＲｂ／ｍｌ细胞·分－１）降低（Ｐ＜０．０５）；另将病人平均动脉压与摄取率进行相关统计分析，结果呈负相关，（ｒ＝－０．３６，Ｐ＜０．０５）。表明不同年龄、不同血压的ＥＨ患者，对红细胞８６Ｒｂ主动摄取率是不一致的。
In this study, isotope 86Rb was used instead of K + to determine the active uptake rate of 86Rb in erythrocytes in 37 patients with essential hypertension (EH). It was found that the uptake rate of 86Rb (7.33nmol / ml cells · minute -1) in young EH patients was significantly higher than that in control group (4.28nmolRb / ml cells · minute -1) (P <0.05) (4.16nmolRb / ml cells · minute -1) than the control group (5.90nmolRb / ml cells · minute -1) (P <0.05); the other patients mean arterial pressure and uptake rate were statistically analyzed, The results were negatively correlated (r = -0.36, P <0.05). EH patients of different ages and different blood pressure showed that the rate of active uptake of erythrocyte 86Rb was inconsistent.
