A B S T R A C TIntroduction: Because of more exposure to mercury compounds, the prenatal and postnatal neurotoxic effects of mercury compounds have gained more attention in last decade. The aim of this study was to investigate the effects of mercuric chloride intoxication on spinal cord development during prenatal period. Methods: 36 adult Sprague-dawley rats after observing vaginal mating plaq...

mercury is one of the three major environmental metal poisons, and mercuric chloride is a highly reactive compound which can harm cells by a variety of mechanisms including direct interaction with sulphydryl groups of proteins and enzymes, therefore affecting the enzymatic activity. this study focused on the effect of hg++ on horseradish peroxidase (donor: hydrogen peroxide oxidoreductase, ec 1...

This study was undertaken with the objective of standardizing the protocol for the micropropagation of Albizia lebbeck (L.). Seeds were collected from three different colored pods (yellow, dark yellow and brownish yellow) harvested from field grown Albizia tree from November to January and were surface sterilized using different concentration of mercuric chloride (0.050.15 % w/v) for different ...

The renal excretion of renin infused intravenously was studied in anesthetized rats. The renin in the urine was adsorbed onto DEAE cellulose and selectively eluted for separate assay on the rat blood pressure preparation. The influence of saline loading, furosemide, mercuric chloride, and maleic acid was determined by following the changes in renin excretion. Both mercuric chloride and maleic a...

The organomercurial, thimerosal, is at the center of medical controversy as a suspected factor contributing to neurodevelopmental disorders in children. Many neurotoxic effects of thimerosal have been described, but its interaction with principal excitatory and inhibitory neurotransmiter systems is not known. We examined, using electrophysiological recordings, thimerosal effects on GABA and NMD...

INTRODUCTION We have previously observed that Brown Norway (BN) rats display a relative resistance to experimental Chlamydia-induced arthritis. In the present study, we examine an environmental toxin, mercuric chloride (HgCl2), as a modulator of this innate resistance to arthritis. METHODS To assess the effect of the heavy metal exposure, one group of rats received two subcutaneous injections...

Heavy metals have been shown to be strong inhibitors of nitrification in wastewater treatment plants. In this research, the effects of cadmium, copper, and mercury on Nitrosomonas europaea were studied in quasi-steady-state batch reactors. When cells were exposed to 1 microM CdCl2, 6 microM HgCl2, or 8 microM CuCl2, ammonia oxidation rates were decreased by about 90%. Whole-genome transcription...
