Submicron-sized airborne particulate matter (PM) is not collected well on regular quartz or glass fiber filter papers. We used a micro-orifice uniform deposit impactor (MOUDI) to fractionate PM into 6 size fractions and deposit it on specially designed high-purity thin aluminum disks. The MOUDI separated PM into fractions 56–100, 100–180, 180–320, 320–560, 560–1000, and 1000–1800 nm. Since the ...

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...
Chronic pain is a common complication of diabetes. The aim of the present study was to characterise pain behaviour in a high fat diet/streptozotocin (HFD/STZ) model of diabetes in the rat, investigate spinal mechanisms, and determine the effects of antidiabetic interventions. Three-week consumption of a high fat diet followed by single injection of STZ (45 mgkg(-1)) produced sustained changes i...

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...
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...

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 ...
BACKGROUND Conflicting reports about the toxicity of Synedrella nodiflora (L) Gaertn (family Asteraceae), a plant traditionally used in Ghana for the management of epilepsy, abound in literature. The present study evaluates the effect of a 90-day continuous oral administration of a hydro-ethanolic whole plant extract of Synedrella nodiflora (SNE) in male Sprague-Dawley rats. METHODS The toxic...
