与棉酚有关低血钾症不同发病地区自然人群钾摄入量和血清钾水平

A SURVEY ON POTASSIUM INTAKES AND SERUM POTASSIUM CONTENTS OF POPULATION IN THE AREAS WITH DIFFERENT OCCURRENCE RATES OF GOSSYPOL RELATED HYPOKALEMIA

在与棉酚有关低血钾症的高发区上海,中发区四川和不发区山东进行了自然人群钾摄入量和血清钾水平的调查,结果表明,自然人群钾摄入量以上海为最高,山东次之,四川最低,分別为60.1±16.6,58.7±11.1和54.6±13.4mmol/人/日,三地血清钾水平上海为4.2±0.3mmol/L,山东为4.2±0.4mmol/L,四川为4.0±0.3mmol/L。这些结果说明高发病区的上海和不发病区的山东两地钾摄入量和血清钾没有显著差别,与棉酚有关低血钾症的发病可能与当地钾摄入量和血清钾的本底水平无关。

The result of a nutritional survey on potassium intakes of population and serum potassium contents of healthy adults in Shanghai (high occurrence of hypokalemia), Sichun (moderate occurrence of hypokalemia) and Shandong (null occurrence of hypokalemia) revealed that the average daily potassium intakes for the three areas were 60.1±16.6, 54.6± 13.4 and 58.7± 11.1 mmol per capita per day respectively; The serum potassium contents of the three areas were 4.2±0.3,4.0 ±0.3 and 4.2±0.4 mmol/L respectively. These results indicated that the daily potassium intakes and serum potassium contents between Shanghai and Shandong were not significantly different and might suggest that the occurrence of gossypol related hypokalemia in Shanghai and Sichun could not be attributed to the low potassium intakes and low serum potassium contents of the population.
