作者报告了缺钾使普通饮食正常男性的收缩压和舒张压升高。如果是摄取正常钾量的男性,即使给予生理盐水也不影响血压,但缺钾的男性则血压便会升高。该研究是在摄取含普通量食盐(120～200mmol/日)及一定热卡饮食的20～40岁健康男性10人中进行的。这些男性都间隔4～8周分别摄取减量(10mmol/日)或普通量的钾饮食各9天。在摄取普通量钾的男性,9天后的收缩压、舒张压及平均动脉压均比正常值略低,但是,钾摄取不足时,9天后的血压都比正常
The authors report that potassium deficiency increases systolic and diastolic blood pressure in normal male subjects. Men with normal potassium intake did not affect blood pressure even with normal saline, but men with potassium deficiency had elevated blood pressure. The study was conducted in 10 healthy 20 to 40-year-old men with normal salt intake (120-200 mmol / day) and a certain calorie diet. Each of these men received a reduced (10 mmol / day) or normal dose of potassium diet for 9 days at intervals of 4 to 8 weeks. In men taking normal potassium, systolic blood pressure, diastolic blood pressure and mean arterial blood pressure were slightly lower than normal after 9 days, but blood pressure was lower after 9 days than normal
