Abstract
Following a lymphocyte separation technique, the lymphocyte content of magnesium and potassium was determined by atomic absorption spectroscopy in 28 subjects. Simultaneously, skeletal muscle biopsies were obtained by a percutaneous technique and analyzed for magnesium and potassium. In this study there was not significant correlation between the lymphocyte and the skeletal muscle content of magnesium or potassium, except in the group of three normal volunteers and nine patients with mild arterial hypertension.
