Matrix metalloproteinases (MMPs), the key enzymes responsible for matrix degradation, are derived from polymorphonuclear leukocytes during the early stages of periodontitis. The present study determined the levels of GCF matrix metalloproteinase-2 (MMP-2) and metalloproteinase-9 (MMP-9) and salivary MMP-8 in patients with gingivitis and periodontitis and in(More)
Twenty preeclamptic, 25 normotensive pregnant and 25 healthy nonpregnant women were analyzed with regard to serum malonaldehyde (MDA), vitamin E and lipid profile. In preeclampsia, MDA was significantly higher than control. MDA also showed high correlation to the level of blood pressure. Serum cholesterol and triglycerides were increased in normotensive(More)
The present study evaluates the presence of oxidative stress in the uncontrolled diabetic state. Glycemic control reduced the oxidative stress, but total normalization of the parameters of oxidative stress was not achieved, indicating continued oxidant injury despite optimal control of the diabetes. Vitamin E supplementation for 4 weeks in these patients(More)
We studied changes in lipid peroxidation, vitamin E status and lipid profile due to smoking in healthy subjects, patients with acute myocardial infarction (MI), and in stabilized patients surviving MI. A significant increase in malondialdehyde (MDA) concentrations was observed in MI patients, more than in smokers (P<0.05), as compared to control. The plasma(More)
Lipid peroxidation may be involved in cancer and essential nutrients that can scavenge free radicals, such as vitamins E and C, operate in concert. Levels of antioxidant vitamins E and C were estimated in 50 patients with oral cancer and 24 healthy persons served as control. Significantly lower levels of vitamins E and C were observed in oral cancer(More)
BACKGROUND Although experimental studies have demonstrated that reduced glutathione (GSH) is involved in cellular protection from deleterious effects of oxygen free radicals in ischaemia and reperfusion, there are controversial data on the correlation between levels of GSH and the ischaemic process. AIM The present study was planned to evaluate(More)
The present study was planned to assess IGF-1, leptin and cholinesterase levels in maternal blood of both normoglycaemics and hyperglycaemics preeclampsia. Twenty five normotensive pregnant women at the time of delivery were selected in as group I and sub grouped according to blood glucose less than or more than 85 mg/dL as I A (<85mg/dL) and I B(More)
BACKGROUND Umbilical cord blood (UCB) is in contact with all the fetal tissues and can reflect the state of fetus and UCB can be compared with maternal blood. Inflammatory, metabolic and immunological disorders during pregnancy can affect the environment in which the fetus is developing and may produce various alterations. OBJECTIVE To analyze different(More)

Vascular endothelial damage has been implicated in the pathophysiology of preeclampsia. Lipid peroxidation may be involved in the process and essential nutrients that can scavenge free radicals, such as vitamin E and C, operate in concert. Antioxidant vitamins E and C were estimated in 30 preeclamptic and 30 normotensive pregnant women. Significantly(More)
AIMS OF THE STUDY To study lipid peroxidation, magnesium levels (Mg) in plasma and red cells (RBC), superoxide dismutase (SOD) and catalase (CAT) activities in the plasma and RBC of shock patients. METHODOLOGY Twenty five patients with clinically defined septic shock and 30 healthy volunteers were selected for the study to study the parameters of(More)
