title: Intraerythrocyte and serum electrolytes in diabetic patients with hypertension.
abstract: OBJECTIVE
  To determine the serum and intraerythrocyte concentrations of vasoactive ions in patients of diabetes mellitus of either gender with hypertension.
  
  
  METHODS
  Cross-sectional study.
  
  
  METHODS
  The Department of Biochemistry, University of Karachi, from May-June 2002.
  
  
  METHODS
  The study was conducted on 48 volunteers. Out of 48, 24(12 men and 12 women) were hypertensive patients with diabetes mellitus. Remaining (12 men and 12 women) were normal healthy subjects. Biochemical estimations were done by flame photometry and spectrophotometry. Data were analyzed by Two-way ANOVA followed by Newman-Keuls test.
  
  
  RESULTS
  A decrease in serum concentrations of sodium, calcium, magnesium, phosphorus, chloride and intraerythrocyte potassium and an increase in the levels of glucose, haematocrit and intraerythrocyte sodium was observed in both male and female patients with diabetes mellitus and hypertension. No significant changes were observed in serum potassium levels.
  
  
  CONCLUSIONS
  The results suggest that dysregulations of electrolyte balance caused by hyperinsulinemia or altered glucose metabolism may lead to hypertension.
