In order to establish a standard for sodium influx in erythrocytes for the black population, 22Na+ uptake was measured in 29 normotensive black volunteers. Nineteen males and 10 females during the follicular phase of the menstrual cycle were studied utilizing the procedure of Gambhir et al. (1). In the males, cell concentrations ranging from 0.64 to 2.0 X 10(9)/ml showed an influx of 0.42 to 1.34% of the total 22Na+ added, and in the females, using the same erythrocyte concentrations, the 22Na+ influx ranged from 0.37 to 1.1%; these differences were not significant. Intraassay variation of the 22Na+ data was 4.8%. Interassay variations have been explained elsewhere (1). These data provided a range of observed values for 22Na+ uptake in erythrocytes from a subpopulation of normotensive black males and females for comparison with hypertensive patients.
为了建立黑人红细胞钠内流的标准，对29名血压正常的黑人志愿者进行了22Na+摄取量的测定。利用Gambhir等人（1）的方法，对19名男性和10名处于月经周期卵泡期的女性进行了研究。在男性中，细胞浓度范围为0.64至2.0×10⁹/ml，22Na+内流占添加的22Na+总量的0.42%至1.34%；在女性中，使用相同的红细胞浓度，22Na+内流范围为0.37%至1.1%；这些差异不显著。22Na+数据的批内变异为4.8%。批间变异已在其他地方进行了解释（1）。这些数据提供了血压正常的黑人男性和女性亚群体红细胞22Na+摄取量的一系列观测值，以便与高血压患者进行比较。
