OBJECTIVE Preeclampsia is reportedly accompanied by increased plasma lipid peroxidation. However, to date the assays that have been applied to measure lipid peroxides have been relatively nonspecific. A highly specific high-performance lipid chromatographic-chemiluminescence technique was used here to measure lipid hydroperoxides in plasma and red blood(More)
UNLABELLED Extent and rate of absorption of acetylsalicylic acid (ASA) from rapidly dispersing (Acesal Extra) and plain tablets (Acesal) relative to reference 1 (plain tablets, Aspirin) and from microcapsuled tablets (Micristin) relative to comparable listed tablets (reference 2, Colfarit) were assessed in 2 single-dose (0.5 g ASA), open, randomized,(More)
It is postulated that lipid peroxidation plays a role in the pathogenesis of a variety of diseases. Efforts have therefore been made to develop reliable and practicable procedures for quantifying lipid peroxidation products such as lipid hydroperoxides in biological specimens. An iodometric cholesterol colour reagent (Merck, Darmstadt, Germany) can be used(More)
Preeclampsia is accompanied by high fetal and maternal morbidity and mortality and to a high degree responsible for preterm delivery. The pathophysiologic mechanisms underlying this disease remain poorly understood. Accordingly, only few causative or preventive therapeutical strategies are known. One such example for a preventive strategy is the use of(More)
Plasma concentrations of the circulating adhesion molecules ICAM-1 (CD54), VCAM-1 (CD106) were determined in 31 women with pre-eclampsia, 9 women with HELLP syndrome, and 13 women with transient pregnancy induced hypertension (PIH). Data were compared with a control group of 157 healthy pregnant women of the same gestational age. Furthermore, concentrations(More)
OBJECTIVE Fifteen percent of patients who later have hemolysis, elevated liver enzymes, and low platelets syndrome develop initially have nonspecific symptoms. Early diagnosis could ensure adequate obstetric management; however, prognostic biochemical tests are lacking. We hypothesized that elevated hyaluronic acid serum levels might be an early indicator(More)
Using bioluminescence assays for glycerol, free fatty acids, beta-hydroxybutyrate and lactate, we were able to perform complex studies of human energy and lipid metabolism both in serum samples in vivo and in isolated fat cells in vitro. These studies would have been impossible without reliable, specific and highly sensitive luminescence methods.(More)
