The concentration of potassium in plasma and in red blood cells was determined in 948 horses. The coefficient of correlation between the two parameters was low. In 436 of these horses, which were clinically healthy, the red blood cell potassium (RBCK+) levels did not fit within a normal distribution curve, but a bimodal distribution was observed with a section point at 90 mmol/litre. In 90 per cent of these normal horses, mean RBCK+ content was 97.5 mmol/litre. In the remaining 10 per cent, mean RBCK+ concentration was 93.8 mmol/litre. A subdivision into a 'low potassium group' and a 'high potassium group' was made. In 10 out of 15 horses in the 'low potassium group', bimonthly sampling over a period of one year showed that RBCK+ content remained low. In the remaining five horses an increase was observed.
对948匹马的血浆和红细胞中的钾浓度进行了测定。这两个参数之间的相关系数较低。在这948匹马中，有436匹临床健康，其红细胞钾（RBCK+）水平不符合正态分布曲线，而是观察到双峰分布，分界点为90毫摩尔/升。在这些正常马匹中，90%的马匹红细胞钾平均含量为97.5毫摩尔/升。其余10%的马匹红细胞钾平均浓度为93.8毫摩尔/升。将其分为“低钾组”和“高钾组”。“低钾组”的15匹马中有10匹，在一年的时间里每两个月采样一次，结果显示红细胞钾含量一直较低。其余5匹马则观察到有所增加。
