The composition of membrane lipids was studied in 1 7 splenectomized and eight unsplenectomized patients with 8-thalassemia major and compared to normal controls. The results showed a nearly twofold increase in total cell lipids; a reduction in the percentage, but not the absolute amount of phosphatidylethanolammne, and a corresponding increase in phosphatidylcholmne in the lipids; a considerab...

Despite numerous theories, the etiology and pathogenesis of primary varicose veins remain unclear. The etiology of chronic venous diseases (CVDs) known as chronic venous insufficiency (CVI) is related to leukocyte trapping. Leukocyte trapping involves trapping of white cells in vessel walls followed by their activation and translocation outside the vessel. Release of reactive oxygen species (RO...

Several lines of evidence demonstrate that isoflurane anesthesia would be a great risk factor for the patients undergoing surgeries to suffer from postoperative cognitive dysfunction (POCD). Additionally, diabetes is also an important pathogenic factor for the emergence of cognitive dysfunction. If patient is suffering from diabetes, the incidence of cognitive dysfunction greatly increased. We ...

Aluminum toxicity is one of the most deleterious factors for plant growth in acidic soils because over 50% of the world’s potentially arable lands are acidic. In recent years, considerable research has been conducted to understand the mechanisms of Al toxicity and tolerance in plants. This paper reviews the effects of different concentration of Al on plant shoot, root physiological parameters s...

The aim was to study the role of nitric oxide (NO), lipid peroxides (LPX), and uric acid in pre-eclampsia and eclampsia. Plasma levels of NO metabolites (nitrite+nitrate), malonyldialdehyde (MDA), and uric acid and erythrocyte MDA levels were compared between normal pregnant, pre-eclamptic, and eclamptic pregnant women in third trimester. Student's t-test was used for statistical evaluation. Pl...

Background: Multifarious biological activities of Schiff base (SB) derivatives are well-known. Aim: In this study aimed that investigation of pro-oxidant effect of ([(2-hydroxybenzylidene)-3methylurea]) derivative SB and its metal complexes. Material and Methods: Pro-oxidant effect was determined by antioxidant vitamins levels effect against malonyldialdehyde (MDA), which is an indicator of lip...

AIM Lipid peroxidation (LP) is an important factor in tissue damage following head injury. Reactive oxygen radicals which damage cellular components play an important role in ischemic or hypoxic tissue. They initiate the lipid peroxidation process after head trauma. However, antioxidant agents may protect brain tissue against oxidative damage MATERIAL AND METHODS 39 male Swiss Albino rats (20...

BACKGROUND The beneficial effect of Δ-17 FAD is poorly understood. The aim of this study was to investigate the protective mechanism of fatty acids against atherosclerotic (AS) damage induced by oxidized low-density lipoprotein (ox-LDL) in human umbilical vein endothelial cells (HUVECs), and to identify the molecular mechanisms involved. MATERIAL AND METHODS The ox-LDL was used to induce lipoto...

BACKGROUND/AIM This study was designed to identify the effect of pentoxifylline on trinitrobenzene sulfonic acid (TNBS)-induced colitis in rats. MATERIALS AND METHODS Forty-two female Wistar rats were randomly divided into 7 groups: group A, TNBS + intraperitoneal (IP) pentoxifylline; group B, TNBS + IP saline; group C, TNBS + intrarectal (IR) pentoxifylline; group D, TNBS + IR saline; group ...
