INTRODUCTION The depletion of defensive body chemicals called antioxidants may increase the risk of complications from the most common form of diabetes mellitus. This study aims to evaluate blood serum lipid peroxidation product (malondialdehyde), an antioxidant, in non-insulin dependent male and female type 2 diabetic patients. METHODS Blood serum samples were collected from the diabetic pat...

Ferritin and haemosiderin were shown, by the measurement of malondialdehyde production and loss of polyunsaturated fatty acids, to stimulate lipid peroxidation in liposomes. At pH 7.4 ascorbate was additionally required to achieve peroxidation; however, peroxidation occurred at pH 4.5 in the presence of iron-proteins alone. The damage was completely inhibited by the incorporation of chain-break...

       This study was designed to explore the protective effects of ascorbic acid and water extract of Spirulina platensis (blue green algae) on methotrexate-induced lipid peroxidation using goat liver as the lipid source. This in vitro evaluation was done by measuring the malondialdehyde, 4-hydroxy-2-nonenal, reduced glutathione and nitric oxide content of tissue homogenates....

background: obesity is associated with increased lipid peroxidation. it has also been suggested that risk of lipid peroxida­tion increases with increasing body iron stores. the aim of this study was to examine the association of body iron status with the concentration of plasma malondialdehyde (p-mda) as a marker of lipid peroxidation in obese and non-obese women. methods: in a case control stu...

Different techniques for the measurement of lipid peroxidation in isolated hepatocytes have been compared. Measurements of ethane production, chemiluminescence and fluorescent products correlated extremely well with those of malondialdehyde formation. Of the five different techniques studied, measurements of ethane production and chemiluminescence were found to the the most sensitive indices of...

A method was developed for measuring the concentration of lipid peroxidation products in rabbit brain, heart, lung, liver, and kidney tissue. Specimens were homogenized in cold buffer, acidified, and heated to near boiling in the presence of thiobarbituric acid in order to form the malondialdehyde-thiobarbiturate adduct. After centrifugation, the supernatant was injected onto a reversed-phase h...

BACKGROUND The association between lipid peroxidation biomarkers and adipocytokines is hypothesized in preeclampsia but little is known about it. OBJECTIVE he present study was undertaken to determine the association of lipid peroxidation biomarkers measured by the levels of 8-isoprostane and malondialdehyde with adipocytokines leptin and adiponectin in maternal serum of preeclamptic women. ...

Considering drug-induced lipid peroxidation as a possible mediator of drug-induced toxicity and exploiting the free radical scavenging action of antioxidants, the present study was designed to evaluate the antiperoxidative potential of morin on cyclophosphamide/flutamide-induced lipid peroxidation and also to evaluate the effect of morin on cyclophosphamide/flutamide-induced changes in choleste...

This study was performed to determine whether TCDD (50 micrograms/kg; single oral dose) could induce adrenal microsomal lipid peroxidation, which might be correlated to decreased levels of cytochrome P-450 and 21-hydroxylase activity. The amount of malondialdehyde (MDA) formed was significantly higher than controls at days 1 through 5 following TCDD treatment. Microsomal cytochrome P-450 levels...
