Fifty one soil samples werecallected from some wadis i.e.,(El Sheikh Soliman,Sidri,El-Arishia and Bodra) of AduRudeis district, which is lies between mountain chains. These were collected to determined their physical chemical properties assess total available contents Fe, Mn, Zn Cu in a fairly intanse sampling scheme.The results indicate that the texture class varies sandy clay loam, The conten...

Deltamethrin is a broad-spectrum insecticide mainly used to protect crops, fruit and vegetables from mites, ants, weevils, beetle etc. Thus deltamethrin contaminated food of commercial poultry diet may cause toxic effects in broilers and indirect adverse effects on human through food chain. Therefore, hematological and biochemical alterations in White Leghorn birds due to deltamethrin induced t...

Saemund and Dalcnius reported five cases of nodal rhythm directly related to the injection of pancuronium 0.1 mgkg" •. We, too, have witnessed several examples of transient nodal rhythm after the administration of pancuronium and not infrequently this rhythm disturbance has been accompanied by a decrease in arterial pressure. Recent reviews (PrysRoberts, 1981) emphasize the potential deleteriou...

This study aims at determining the level of pollution heavy metals (Cr, Cu and Hg) in soils illegal mining sites Atiwa East District Ghana. The concentrations Copper (Cu), Chromium (Cr), Mercury (Hg) were determined using Atomic Absorption Spectrometry (AAS). extent metal risk assessment was analyzed site. Thirty (30) soil samples collected from three (3) within district. average levels Cu, Cr,...

abstract nickel is a heavy metal distributed ubiquitously in nature. it accumulates in soil as a result of human activities, including mining and industries development. it may be poisonous to plants, humans, animals and microorganisms. the present study was implemented as a factorial experiment with a randomized complete block design (rcbd), of three replications in calcareous soils of karaj a...

The dietary iron requirement for normal growth and optimum hematological values and bioavailability was determined for channel catfish Ictalurus punctatus fingerlings using eggwhite based diets supplemented with 0,5,10,20,60, and 180-mg ironkg from iron methionine or 20, 60, and 180-mg ironkg from iron sulfate. The basal diet which contained 9.2-mg ironkg, 34% crude protein and 3.1 kcal of dige...

Chronic nicotine (NIC) pretreatment has been shown to enhance NICinduced locomotor stimulation, an effect that seems critically dependent on activation of brain dopamine (DA) systems. In the present study the effects of chronic, intermittent NIC treatment were examined in the rat to establish whether such behavioral sensitization is associated with specific, regional changes in brain dopaminerg...

The study was conducted to evaluate hydraulic conductivity functions in relation to some soil chemical properties in an oxisols of the tropics. Field and laboratory studies were carried out and data collected, subjected to statistical analytical procedure for computing coefficient of variability and correlation among soil properties. Results of the study showed that hydraulic conductivity funct...

Daily intraperitoneal injection of cyclophosphamide (CPA) (50 mgkg(-1) of body weight) for 5 days resulted in reduced levels of marrow and blood cellularity, which was most pronounced in 18 days post-treatment (pt). On day 18 after CPA treatment the enhancedlevels of nitric oxide (NO) precursors and metabolites (L-arginine, L-citrulline, reactive nitrogen species (RNS)) of marrow and blood cell...
