治疗肾小球肾炎(肾变病型及高血压型)时一般主张应限制饮食中的钠含量。但也有人认为应在饮食中供给足够数量的钠。摄入适当数量的钠可使肾小球滤过率、肾血流量以及细胞外液保持在患病前水平;而限制饮食中的钠时,这些指标显见下降,以至引起或加重肾功能不全。作者认为,钠在肾变病型及高血压型慢性肾小球肾炎时所产生不良影响,与其说是由钠所引起,不如说是由钠和氯离子结合所引起。因而 Treatment of glomerulonephritis (nephropathy and hypertension type) is generally advocated should limit the sodium content in the diet. But some people think that a sufficient amount of sodium should be supplied in the diet. Intake of an appropriate amount of sodium keeps the glomerular filtration rate, renal blood flow, and extracellular fluid at the pre-sick level; while limiting sodium in the diet, these indicators are significantly reduced, causing or worsening renal insufficiency. The authors believe that the adverse effects of sodium on nephrosis and hypertensive chronic glomerulonephritis are not so much caused by sodium, but rather by the combination of sodium and chloride. thus
