The mechanisms of action of lead on the developing central nervous system is still uncertain. They may be related to a composition between lead and calcium on the synaptosomal level. Among the typical stochastic risks, tumors have been found in lead-intoxicated rodents, but do not seem to ...
Lead Toxicity: Does the Critical Level of Lead Resulting in Adverse Effects Differ between Adults and Children? we provided an overview of studies addressing the critical level of lead in workers, together with a perspective on lead toxicity in children.In 25 report... K Murata,T Iwata,M Dake...
Although the mean lead levels found were lower than the current laboratory references, low levels have been associated with both rising morbidity and mortality. The WHO stated: "There is no known level of lead exposure that is considered safe". In conclusion, this work showed that bullets ...
At the ultrastructural level, sublethal concentrations of the heavy metals tested caused induced cell plasmolysis and alterations of the chloroplast arrangement. Heavy metal removal experiments revealed that the three macrophytes showed excellent performance in removing the selected metals from the solutions ...
per kg. body weight may be tolerated for many months, and that a level of 6 mg. per kg. of body weight per day may be tolerated for even three years. On the basis of a single experiment it is suggested, that much smaller amounts of lead, 1 mg. per kg. per day, are sufficient...
families with children at risk for lead toxicity.Two geographic wards in Jos, Nigeria were selected for study, one previously reported to have a high mean blood lead level (37 (SD 13) microg/dl) and one with a lower mean blood lead level (17 (SD 10) microg/dl) in young children. ...
Arsenic significantly enhanced lipid peroxidation, electrolyte leakage, and level of proline showing oxidative stress. Arsenic toxicity was associated with an increase in the activities of antioxidative enzymes like superoxide dismutase, peroxidase, and ascorbate peroxidase whereas catalase activity decreased ...
3). Furthermore, the results also showed that NF-кB level in the Cd group was markedly elevated (p < 0.05) when compared with that of normal and ASP control rats, while treatment with ASP significantly modulated NF-кB level in comparison to the Cd group (Fig. 3). Figure 3 ...
