Abstract: | Calcium disodium ethylenediaminetetraacetate (Ca-Na2EDTA; Versenate) was more effective than thiamine (vitamin B1) in enhancing the urinary excretion of lead, reducing tissue lead and restoring lead induced biochemical alterations in rats. However, the combination of CaNa2EDTA and vitamin B1 enhanced the beneficial effect of CaNa2EDTA in lead intoxication and was particularly effective in reducing the brain concentration of lead. |
