The concentrations of sodium, potassium, and chloride in various control sera were determined by reference methods. The reference method values were compared with the corresponding method-dependent assigned values. Sodium: Measurements by flame photometry and ion selective electrodes differed on the whole by less than 1% from the reference method value; determinations by photometry differed, ho...

To clarify the relationship between the catalase activity in mouse organs and the amounts of metallic mercury exhaled, normal, homozygous hypocatalasemic and acatalasemic mice were injected with mercuric chloride. The cumulative amount of metallic mercury exhaled by mice was evidently expressed in the descending order of acatalasemic, hypocatalasemic, and normal mice. Statistically significant ...

FT-IR spectra of liver tissue isolated from mice, Mus musculus, have been recorded in the region of 4000 – 400 cm-1 for normal, mercury treated and recovery phase. In this study, the total protein content was found to be decreased in the liver tissues after treatment with median-lethal dose of mercuric chloride. The marked fall in the level of bio-chemical constituent in the tissue due to metal...

In the performance of routine determinations of serum chloride by the automated method, which depends on halide displacement of mercury from the thiocyanate to allow formation of ferric thiocyanate complex, 4 cases of bromide poisoning were detected. Experimental evidence shows the halide substitution to be an equilibrium, with higher formation constants for the heavier halide ions. As a result...

Renal disposition of administered inorganic mercury was studied in rats that had undergone an acute bilateral ureteral ligation shortly before being injected with a nontoxic 0.5-micromol/kg iv dose of inorganic mercury with or without 2.0 micromol/kg glutathione (GSH) or cysteine. Ureteral ligation and induction of "stop-flow" conditions were carried out to decrease glomerular filtration rate t...

introduction: wastewaters of chemical, petrochemical, electrical, pharmaceutical and paper industries are the main sources of mercury and its compounds. mercury is one of the toxic elements, so its removal from water and industrial wastewaters seems to be important and essential. the objective of this study was to investigate effective factors such as ph, contact time, absorbent dose, mixing ra...

As very little information was available on mercury sensitivity testing, the first aim was to determine the most suitable agar and concentration of mercuric chloride to use in this project. The primary objective o f the study was to determine whether mercury released from amalgam fillings could increase the prevalence o f mercury-resistant bacteria in the oral flora of children. This was achiev...

BACKGROUND Environmental toxins are suspected to play a role in the pathogenesis of amyotrophic lateral sclerosis (ALS). In an attempt to determine which pathways these toxins can use to enter motor neurons we compared the distribution of mercury in the CNS of a human and of mice that had been exposed to inorganic mercury. RESULTS In the human who had been exposed to metallic mercury, mercury...

Curcumin, a safe nutritional component and a highly promising natural antioxidant with a wide spectrum of biological functions, has been examined in several metal toxicity studies, but its role in protection against mercury toxicity has not been investigated. Therefore, the detoxification and antioxidant effects of curcumin were examined to determine its prophylactic/therapeutic role in rats ex...

Concentrations and loads of total mercury and methylmercury were measured in streams draining abandoned mercury mines and in the proximity of geothermal discharge in the Cache Creek watershed of California during a 17-month period from January 2000 through May 2001. Rainfall and runoff were lower than long-term averages during the study period. The greatest loading of mercury and methylmercury ...
