Selenium (Se) is an essential element for many organisms but also toxic at higher levels. The objective of this study was to identify accessions from the model species Arabidopsis thaliana that differ in Se tolerance and accumulation. Nineteen Arabidopsis accessions were grown from seed on agar medium with or without selenate (50 microM) or selenite (20 microM), followed by analysis of Se toler...
Ibuprofen is an effective, cheap, and frequently used non-steroidal anti-inflammatory drug. The present study investigated the doseand time-dependent effects of ibuprofen on hepatic, renal, and hematological functions in rats. Groups of rats (n=6) were given ibuprofen (20, 40 mgkg -1 day -1 ) for 7, 14 or 28 days; or vehicle (control), orally. Blood samples were obtained, and hematological indi...
The effectiveness of 1,2-dimethyl-3-hydroxypyrid-4-one (Ll) in increasing iron excretion in iron-loaded patients improved the propsects for replacing desferrioxamine (DF) with an oral chelating drug.’,’ L1 belongs to a new group of iron chelators, the a-ketohydroxypyridines (KHP); which are cheap to p ~ e p a r e ~ . ~ and orally active. Recently, a detailed article by Porter et al.’ on in vivo...
Lead (Pb) is the most ancient poison known to man. In the present study, amount of accumulation of Pb in liver, kidney, ovary and testes of rain quail was studied using different doses of lead. Spectrophotometric analysis of heavy metal treated organs was carried out to determine the amount of metal accumulation in these organs. LD50 value was 4 ppm. Dose of lead was given in three ranges of lo...
in this study, a simple, rapid and selective method was developed for the determination of dexamethasone. the proposed method is based on inhibitory effect of dexamethasone on the oxidation of orange-g by bromate in sulfuric acid media. the reaction was followed spectrophotometrically at 478.5 nm (?max). under optimum experimental conditions, (72.6 ?mol l-1 of orange-g, 0.76 mol l-1 of h2so4, 0...
environmental pollution with heavy metals is a global disaster that is related tohuman activities. this study was conducted to determine the extent of heavy metalsaccumulation by plant species in lia industrial city (qazvin, iran) and to investigate theremediative capacity of native plant species grown in the contaminated soils. soil andindustrial wastewater sampling was done radially along tra...
Estrogen deficiency was produced in female Sprague-Dawley rats by surgical removal of both the ovaries and these animals were used 4 weeks later. Endothelium-dependent and endothelium-independent relaxations due to acetylcholine and sodium nitroprusside were observed respectively, in isolated rat thoracic aortic ring preparation. Extent of lipid peroxidation was measured by estimating serum TBA...
Owing to the importance of clean and fertile agricultural soil for the continued existence of man, this study investigated the concentrations of total petroleum hydrocarbons (TPHs), polycyclic aromatic hydrocarbons (PAHs) and some heavy metals in soils and selected commonly consumed vegetables and tubers from oil-polluted active agricultural farmland in Gokana of Ogoniland, Rivers State, Nigeri...

The aim of the present study was to investigate the effect of Lactococcus lactis and Weissella cibaria probiotics on growth performance, intestinal bacterial flora, digestive enzymes and intestinal histology in common carp (Cyprinus carpio). Fish with an average initial weight of 17 g were divided into 10 treatments with 3 replications. Fish food in treatments 1, 2 and 3 were supplemented with ...
