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...

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...

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...

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...

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...

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...

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,...

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...
