The Manganese concentration in red blood cells and serum of Filipinos

The mean concentration of manganese in the red blood cells and serum of normal healthy subjects and patients with old myocardial infarct and diabetes mellitus was determined by neutron activation analysis. The mean concentration of manganese in the red blood cells and serum of patients with old myocardial infarct (0.57+-0.45 ug/g and 0.23+-0.18 ug/g) and patients with diabetes mellitus (0.55+-0.4 ug/g and 0.24+-0.19 ug/g) were higher than normal levels of 0.11+-0.08 ug/g and 0.19 +-0.16 ug/g respectively. The importance of the investigation was discussed. (Summary)
