In vivo 31P-MRS assessment of muscle-pH, cytolsolic-[Mg 2+] and phosphorylation potential after supplementing hypokaliuric renal stone patients with potassium and magnesium salts
Renal stone patients in rural northeast Thailand have a low potassium and magnesium status and low urinary excretion of citrate. We measured the changes of urinary citrate excretion and assessed in vivo skeletal muscle metabolism for intracellular-pH, cytosolic-[Mg 2+] and phosphorylation potential...

| description | Renal stone patients in rural northeast Thailand have a low potassium and magnesium status and low urinary excretion of citrate. We measured the changes of urinary citrate excretion and assessed in vivo skeletal muscle metabolism for intracellular-pH, cytosolic-[Mg
2+] and phosphorylation potential (using the phosphorus magnetic resonance spectroscopy
31P-MRS) after oral supplementation to hypokaliuric renal stone patients with oral potassium and magnesium salts. The patients comprised four groups: Group 1 (n = 10) control, Group 2 (n = 3), Group 3 (n = 5) and Group 4 (n = 6) supplemented for a month with potassium citrate, potassium citrate plus amino acid chelated magnesium, and potassium-magnesium citrate, respectively. Though urinary citrate excretion was increased in all three supplemented groups, the increases in intracellular-pH, cytosolic-[Mg
2+] and phosphocreatine (PCr)/β-ATP were prominent only in Group 3. The increase in PCr/β-ATP was also observed in Group 4. |
