有人做过一个试验:一组大白鼠给予足够的含钾食物,另一组给予缺钾的食物,同时置于相同的酷热环境中。结果,缺钾组半数以上死亡,而补钾组则全部安然无恙。临床医学研究也发现,凡出现头晕、恶心、乏力、心律紊乱、甚至昏迷的中暑病人,其血钾浓度多有下降。钾离子为人体最重要的阳离子之一。正常人体内钾总量约为 Someone has done a test: a group of rats given enough potassium-containing food, the other group given potassium-deficient food, while placed in the same hot environment. As a result, more than half of the potassium-deficient group died, while the potassium-supplement group was all safe and sound. Clinical studies also found that any dizziness, nausea, fatigue, arrhythmia, and even coma in patients with heat stroke, the serum potassium levels have dropped. Potassium is one of the most important cations in the body. Normal human total potassium is about
