钾是生命必需的矿物质之一。晚近,由于火焰光度计和同位素等在临床上的应用。对钾的代谢,特别对钾缺乏症等问题有了新的认识。正常情况下,绝大部份体内钾(约占钾总量的98%)存在于细胞内。在某些条件下,细胞内钾外移或细胞外钾移向细胞内,使细胞内外钾浓度改变,造成高血钾或低血钾以及由此而产生的一系列症状。本文介绍10例体内钾分布异常的周期性麻痹,并进行分析和讨论。临床资料分析:男性7例,女性3例。年龄:21～50岁,以男性青年为主。以往有发作史6例,有家属史1例。均无甲亢或心、肾病史。
Potassium is one of the minerals essential to life. Recently, due to the flame photometer and isotopes and other clinical applications. The metabolism of potassium, especially for potassium deficiency and other issues have a new understanding. Under normal circumstances, most of the body potassium (about 98% of the total potassium) exist in the cell. Under certain conditions, intracellular potassium extracellular or extracellular potassium to the cells, so that changes in intracellular and extracellular potassium concentration, resulting in hyperkalemia or hypokalemia and the resulting series of symptoms. This article describes the 10 cases of abnormal potassium distribution in the body of periodic paralysis, and analysis and discussion. Clinical data analysis: 7 males and 3 females. Age: 21 ~ 50 years old, mainly male youth. Past episodes in 6 cases, a family history of 1 case. No hyperthyroidism or heart, kidney disease history.
