Preeclampsia is a disease characterized by hypertension and significant proteinuria that occurs after the twentieth week of pregnancy. The presence of mechanisms that detoxify free oxygen radicals associated with increased oxygen consumption in preeclampsia is very important. In mitochondrial and microsomal systems, molecular oxygen is reduced by taking an electron and superoxide radical is formed which is an unstable structure. Superoxide Dismutase is a metalloenzyme which converts superoxide radical to Hydrogen Peroxide. Glutathione Peroxidase degrades hydrogen peroxide by converting it into water and molecular oxygen using glutathione. Twenty-seven preeclampsia patients and 32 healthy pregnant control groups were selected at 20-28 weeks of gestation. There was a significant difference (p

Diabetes Mellitus is the most common of the serious metabolic diseases. It is characterized by metabolic abnormalities; by long-term complication. Correlation between erythrocyte membrane Na+K+ATPase and plasma homocysteine levels in patient. This study was conducted in 29 patients with Type II Diabetes Mellitus and 15 healthy controls. Erythrocyte membrane Na+K+ATPase activity and malondialdehyde were measured spectrophotometrically. Plasma homocysteine levels were measured with High Performance Liquid Chromatography method. When compared to the control group, mean plasma homocysteine levels were found to be increased (p
