Abstract

The aim of this study was to determine whether the paraoxonase (PON1) status, i.e. PON1 activities and phenotypes (AA, AB and BB), and its relationship with lipid status are different in patients with type II diabetes as compared to healthy population. Diabetic group comprised 175 patients with type II diabetes mellitus (94 men and 81 women) who came to their regular control examination and took the oral glucose tolerance test. Patients with type II diabetes mellitus diagnosis for 12 years on average were on peroral antidiabetics, or insulin or diet, and 3 patients had no therapy prescribed yet. Control group comprised 114 apparently healthy individuals (28 men and 86 women) who were not on any medication. The paraoxonase activity was measured with 2.0 mmol L(-1) paraoxon in the absence and in the presence of 1.0 mol L(-1) NaCl, and with 2.0 mmol L(-1) phenylacetate. Both activities were measured spectrophotometrically at 37 degrees C in 0.1 mol L(-1) Tris-HCl buffer, pH = 8.0, containing 2.0 mmol L(-1) CaCl(2). Sera of diabetic and control subjects were assigned to the paraoxonase phenotypes on the basis of the basal paraoxonase activity distribution. We assigned 45% sera of male and 49% sera of female diabetic patients, and 6...Continue Reading
