SUMMARY The purpose of this study is to compare the level of zinc, copper and the ratio of zinc to copper in serum of patients who are suffering from acute myocardial infarction with healthy men. In 10 ml blood samples from 45 men on the second day of myocardial infarction and 51 healthy men volunteers matched for age, serum zinc, copper, cholesterol and triglycerides were measured. Zinc and c...

There are many remediating methods for the polluted soils but only phytoremediation is a cost effective, environmental friendly, aesthetically pleasing approach that is most suitable for many countries. The purpose of this study was to investigate the potential of native plants for phytoremediation of contaminated soils with lead, zinc, cadmium and nickel in the rangelands around National Lead ...

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...

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...

This study was carried out to investigate the preventive effects of galactoglucomannan (GGM), a homogeneous polysaccharide from Dendrobium huoshanense, on liver injury and fibrosis induced by sodium selenite. Sprague-Dawley rats injected subcutaneously with sodium selenite at the dosage of 3.28 mgkg(-1) b.wt. were set as the model groups. Rats treated with sodium selenite at the dosage of 3.28 ...

We investigated the influence of soil properties on availability or otherwise micronutrients in agricultural soils impacted by inorganic and organic manures South-South Area Nigeria. The levels pH, matter (OM), cation exchange capacity (CEC), copper (Cu), iron (Fe), manganese (Mn), zinc (Zn) understudy were examined. measured OM, CEC, Cu, Fe, Mn Zn revealed: 6.04±0.49, 17.68±4.78 %, 7.97±0.81 C...

Sleep spindles and spike-wave discharges are thought to originate from the same thalamic pacemaker. In the present work it is investigated whether sleep spindles and spike-wave discharges are also sensitive for the same drugs. Adult male WAGIRij rats were chronically implanted with frontal and occipital EEG electrode pairs. Rats were intraperitoneally injected with clonidine (0.00625 mgkg), phe...
