BACKGROUND Ischemia reperfusion injury (I/R) in hind limb is a frequent and important clinical phenomenon. Many structural and functional damages are observed in cells and tissues in these kinds of injuries. In this study, we aimed to evaluate the effect of picroside II on lipid peroxidation and erythrocyte deformability during I/R in rats. METHODS Rats were randomly divided into four groups ...

Cadmium (Cd) is a highly toxic heavy metal, wide occupational and an environmental pollutant, affecting human health. Probiotics especially lactic acid bacteria (LAB) have the capacity to bind, remove and to decrease tissue cadmium levels. The objective was to evaluate the potency of Cd binding capacity, antioxidative properties of probiotic bacteria against cadmium in vitro and its probable de...

AIM Hypothetically, supplementation with the antioxidant vitamins C could alleviate exercise-induced lipid peroxidation. The purpose of this study was to evaluate the effect of vitamin C supplementation on exercise-induced lipid peroxidation, muscle damage and inflammation. METHODS Sixteen healthy untrained male volunteers participated in a 30-min exercise at 75% Vo2max. Subjects were randoml...

BACKGROUND Oxidative stress in reproductive system leads to sperm DNA damage and sperm membrane lipid peroxidation and may play an important role in the pathogenesis of male infertility, especially in idiopathic cases. Antioxidants such as carotenoids function against free radical damages. OBJECTIVE The aim of this study was to determine the levels of lycopene, beta-carotene and retinol in se...

This study looks at the changes in MDA and LDH levels after a 30 km cycling event Makassar community. research is pre-experimental with one-group pretest-posttest design on male cyclists aged 30-60 years. The pre-test was carried out day before event, then post-test 2 hours event. Blood samples were tested using ELISA Kit. Data analyzed Wilcoxon test to see effect of levels. Spearman correlatio...

OBJECTIVES The increasing number of devices emitting electromagnetic radiation (EMR) in people's everyday life attracted the attention of researchers because of possible adverse effects of this factor on living organisms. One of the EMR effect may be peroxidation of lipid membranes formed as a result of free radical process. The article presents the results of in vitro studies aimed at identify...

During a haemodialysis (HD), because of the contact of blood with the surface of the dialyser, the immune system becomes activated and reactive oxygen species (ROS) are released into plasma. Particularly exposed to the ROS are lipids and proteins contained in plasma, which undergo peroxidation. The main breakdown product of oxidized lipids is the malondialdehyde (MDA). A common method for measu...

The effects of the exudate of Aloe barbadensis leaves on oxidative stress and some antioxidant status of streptozotocin induced diabetic rats were studied. There was significant reduction in scavenging enzymes like superoxide dismutase (SOD) activity and significant increase in signs of oxidative tissue damage, such as lipid peroxidation products (plasma MDA) in streptozotocin induced diabetic ...

Free radicals play an important role in pathological processes such as aging and developing cancer; hence, natural products inhibit free radical production, and can play an important role in preventing diseases. We aimed to evaluate the scavenging activity of free radicals, reducing power, inhibition of lipid peroxidation and malondialdehyde (MDA) formation, and the antioxidant composition of r...
