A 5-yr study was conducted to measure the rates of recovery of fish and invertebrate communities following reclamation of a watershed impacted by an abandoned coal surface mine in Southwest Missouri. Quarterly monitoring of water quality information (pH, conductivity, and alkalinity) was conducted at 10 sites. Annual monitoring of biological (benthic invertebrate and fish community structure), ...

In a recent article in Immunology Today, Wellinghausen et al.1 reviewed the various interactions between zinc and the immune system. The authors clearly pointed out that zinc (zinc ions and/or chelated zinc) plays an important role in the maintenance of immune function. Zinc deficiency results in hypoplasia of the immune system, impaired immune response, poor wound healing, diminished T-cell de...

In this study, a hydrometallurgical treatment involving the solvent extraction and recovery of some heavy metals from a sulphuric acid leach solution of galvanic sludge, using di-(2-ethylhexyl)-phosphoric acid (D2EHPA) and bis-(2,4,4-trimethylpentyl)-phosphinic acid (Cyanex 272), both diluted in kerosene, has been investigated. The preliminary tests revealed the necessity to remove other metal ...

The effect of zinc supplementation on intestinal permeability changes and protein loss was studied in 32 children aged between 1 and 12 years during bouts of acute shigellosis and after recovery. An intestinal permeability test and then a 48 hour balance study were performed on all patients. They were then blindly assigned to receive vitamin B syrup either with or without zinc acetate (15 mg/kg...

AIM To determine the drug action mechanism of pollen extract EA-10, P5 on the treatment of chronic prostatitis (CP) or infertility with CP. METHODS Malondiadehyde (MDA), superoxide dismutase (SOD), and nitrogen monoxide (NO) were measured by biochemical assay, and zinc content was assayed by atomical spectrophotography in the pre-treatment and post-treatment of CP or infertility with CP. RE...

Different dilutions, that is, 25, 50, 75, and 100%, of tannery effluent (TE) were chosen for the present study to assess the phytotoxic effects on Vigna mungo L. For amelioration purposes, different levels and combinations of iron and zinc were supplied to the plants along with 50% TE that is chosen on the basis of prior test under Petri dish culture. Cytotoxic and biochemical analysis and plan...

INTRODUCTION The diagnosis of intestinal parasitic infections depends on the parasite load, the specific gravity density of the parasite eggs, oocysts or cysts, and the density and viscosity of flotation or sedimentation medium where faeces are processed. OBJECTIVE To evaluate the concordance between zinc sulphate flotation and centrifugal sedimentation in the recovery of parasites in faecal ...
