为了避免用词上的困难本文将通篇以氨代表(NH_3)及铵离子(NH_4~+的总和.虽然,大家都知道在生理pH范围99%是以铵离子形式存在,但在测定时都转换成氨.高血氨的原因高血氨见于遗传性尿素循环缺陷,亦继发于某些氨基酸与有机酸的代谢障碍.肝功能损伤可产生明显的高血氨,也偶见于某些其它疾病.其原因见表1. In order to avoid the difficulty of terminology, throughout this article, ammonia is used as the representative of (NH 3) and the sum of ammonium ions (NH 4 +.) Although it is known that 99% of the physiological pH is in the form of ammonium ions at physiological pH Into ammonia. The cause of hypernatremia Hypernatremia is found in hereditary urea cycle defects, but also secondary to metabolic disorders of certain amino acids and organic acids .Human dysfunction can produce significant hypernatremia, and occasionally in some other The reason for this is shown in Table 1.
