Abstract

In 11 controls and 10 patients suffering from untreated uraemic acidosis intracellular bicarbonate and skeletal muscle pH (needle biopsy) were determined. In all patients a significant intracellular acidosis, not related to any extracellular indices was found. It is concluded that the chronic proton load is able to effect intracellular buffer composition; moreover the action of other factors such as derangements of cell metabolism and nutritional imbalance could be operating.

慢性肾衰竭时骨骼肌细胞内碳酸氢盐和pH的变化。
在11名对照组和10名未经治疗的尿毒性酸中毒患者中,测定了细胞内碳酸氢盐和骨骼肌pH值(针活检)。所有患者均有明显的细胞内酸中毒,与任何细胞外指标无关。结果表明,慢性质子负荷能够影响细胞内缓冲液的组成;此外,细胞代谢紊乱、营养失衡等其他因素也可能起作用。
