A 28-year-old female presented for evaluation of left flank pain and polyuria after having been exposed to cadmium in the jewelry manufacturing industry for approximately 3 years. This patient possessed both elevated 24-hr urinary ss2-microglobulin and elevated blood cadmium levels. Approximately 6 months after initial presentation, the patient resigned from her job due to shortness of breath, ...

BACKGROUND In Mae Sot District, Tak Province, Thailand, the paddy fields receiving irrigation from the two creeks and crops grown in the areas were found to contain markedly elevated cadmium levels during the surveys in 2001-2004. OBJECTIVE The present report carried out a survey in 2004 to determine urinary cadmium, a good index of excessive cadmium exposure and body burden, among the expose...

The mechanism of cellular uptake of cadmium, a highly toxic metal ion, is not known. We have studied cadmium uptake and toxicity in an established secretory cell line, GH4C1, which has well characterized calcium channels. Nimodipine, an antagonist of voltage-sensitive calcium channels, protected cells against cadmium toxicity by increasing the LD50 for CdCl2 from 15 to 45 microM, whereas the ca...

Vitamin D deficiency in cadmium-exposed rats was observed along with enhanced tissue cadmium accumulation. In relation to the barrier function, the changes in the lipid composition have been studied in the intestinal brush border membranes prepared from rats raised on diets differing in vitamin D status in the absence or presence of cadmium. In an analysis of lipid composition, vitamin D3 treat...

This study concerns the metabolism of polyphosphate in Trichoderma harzianum, a biocontrol agent with innate resistance against most chemicals used in agriculture, including metals, when grown in the presence of different concentrations of cadmium. The biomass production was affected by the concentration of metal used. Control cultures were able to accumulate polyphosphate under the conditions ...

Wheat genotypes with different endogenous SA contents were investigated, in order to reveal how cadmium influences salicylic acid (SA) synthesis, and to find possible relationships between SA and certain protective compounds (members of the antioxidants and the heavy metal detoxification system) and between the SA content and the level of cadmium tolerance. Cadmium exposure induced SA synthesis...

In many neurodegenerative disorders, aggregates of ubiquitinated proteins are detected in neuronal inclusions, but their role in neurodegeneration remains to be defined. To identify intracellular mechanisms associated with the appearance of ubiquitin-protein aggregates, mouse neuronal HT4 cells were treated with cadmium. This heavy metal is a potent cell poison that mediates oxidative stress an...

Heavy metal intoxication is a consequence of the accumulation metals in body. The toxicity heavy metals, particularly lead, arsenic, cadmium and mercury, remains significant problem challenge for future investigations.

The heavy metal cadmium (Cd(2+)) applied on tobacco roots in the form of cadmium chloride, induced significantly higher levels of DNA damage as measured by the cellular Comet assay than did treatment of isolated root nuclei, analyzed by use of the acellular Comet assay. DNA damage induced by Cd(2+) in roots of a transgenic catalase-deficient tobacco line (CAT1AS) was higher than in wild-type to...
