homalium letestui pellegr (flacourtiaceae) is used traditionally by the ibibios of southern nigeria to treat stomach ulcer, malaria and other inflammatory diseases and yorubas of western nigeria as an antidote. the hepatoprotective effect of the stem extract (200-600 mg/kg) was evaluated by the assay of liver function parameters, namely total and direct bilirubin, serum protein and albumin, tot...

conclusions gallic acid and csa combination improved antioxidant capacity and cell membrane integrity more than each one alone. therefore, it can be a therapeutic approach to reduce the i/r injury. background myocardial infarction is one of the important causes of death during old ages. gallic acid as an antioxidant or cyclosporine a (csa) as inhibitor of mitochondrial permeability transition p...

Objectives: To study the antioxidant capacity of Murraya koeingii essential oil (MKEO) phytoconstituents Methods: It was determined by using GCMS. The were then exposed to molecular docking studies that targeted dopamine D2 look for neuroprotective effects. highest percentage content constituents selected as ligands and dopamine(6VMS) retrieved from protein data bank, performed Schrodinger soft...

Oxidant carcinogens interact with multiple cellular targets including membranes, proteins, and nucleic acids. They cause structural damage to DNA and have the potential to mutate cancer-related genes. At the same time, oxidants activate signal transduction pathways and alter the expression of growth- and differentiation-related genes. Indeed, the carcinogenic action of oxidants results from the...

Background: The mechanism of para-nonylphenol (PNP) reducing the proliferation and differentiation of bone marrow mesenchymal stem cells (MSCs) is not known. The present study was designed to investigate the mechanism. Methods: MSCs were extracted under sterile condition from Wistar rat and cultured in DMEM, containing 15 % FBS and penicillin/streptomycin until the 3rd passage, then cells we...

Salinity is a major limiting factor for plant growth and development. To evaluate the impact of P5CS gene expression under in vitro salt stress condition, transgenic tobacco (Nicotiana plumbaginifolia) carrying P5CS gene and non-transgenic plants were treated with 0, 100, 150, 200 or 250 mM NaCl for 28 days. Proline content, lipid peroxidation and the activity of some antioxidant enzymes after ...

objective: crocin, the carotenoid isolated from saffron, has numerous medicinal properties which include anticancer and antioxidant activities. some antioxidants, such as carotenoids, can act as pro-oxidants at higher dosages and therefore induce tissue damage. in this situation antioxidant defense systems in the liver activate to prevent tissue damage. this study investigates the possible toxi...

Increase in carbon dioxide level is considered as a threat to all living organisms and particular aquatic are vulnerable. Although number of studies were carried out predict the effect increased CO2 with marine organisms, fresh water fish least concerned ones. Therefore, aim this study was antioxidant enzymes zebrafish exposed acute concentration (based on prediction for 2300). Three ranges pH ...

mammea africana sabine (guttiferae) stembark, a common plant, traditionally used to treat various diseases and ailments was evaluated for hepatoprotective potentials against paracetamol- induced liver injury in rats. the hepatoprotective effect of the stembark extract (30-90 mg/kg) was evaluated by the assay of liver function parameters: total and direct bilirubin, serum protein and albumin, to...

BACKGROUND The aim of this study was to evaluate the plasma concentrations of malondialdehyde (MDA) and nitric oxide (NO) and the plasma activities of oxidant and antioxidant enzymes in patients with IBS. MATERIAL/METHODS A total of 36 patients with IBS were included in the study. Thirty-five healthy subjects were selected to form the control group. Superoxide dismutase (SOD), catalase (CAT),...
