AB  - The CaNa(2)EDTA chelation therapy is often practiced with antioxidant supplementation. Dry olive leaf extract (DOLE) is natural product with antioxidant and DNA protective properties. The effects of DOLE on the levels of DNA damage were investigated ex vivo in peripheral blood lymphocytes (PBLs) of 19 workers occupationally exposed to lead (Pb), before and after CaNa(2)EDTA chelation therapy. POLE demonstrated pronounced radical scavenging activity in concentrations >= 1 mg/mL, and showed no genotoxicity per se, in concentrations 0.125-1 mg/mL. The level of DNA damage in PBLs of workers before chelation therapy was elevated (24.21 +/- 14.26) compared to controls (6.0 +/- 3.37). The incubation of PBLs before chelation therapy with selected concentration of DOLE lead to a severe increase of DNA damage (64.03 +/- 20.96), exhibiting prooxidant rather than antioxidant effect. After the five-day CaNa2EDTA chelation regimen, DNA damage in PBLs of workers decreased (8.26 +/- 4.62) significantly compared to baseline. Treatment of PBLs with DOLE after chelation, again produced high level of damage (41.82 +/- 23.17) and the acute prooxidant effects of DOLE remained, but, DNA damage was less severe than before chelation. The DOLE exhibits prooxidant effect in presence of Pb in lymphocytes of exposed workers, and its effect is less pronounced following the removal of Pb after standard chelation therapy.

AB  - The aim of this study was to determine oxidative alterations leading to cellular dysfunctions in Pb-exposed subjects by evaluating damage to all major classes of biomolecules in the cell, lipid peroxidation, protein and DNA damage and determine relationships between parameters of Pb toxicity and specific biomarkers of oxidative damage.Analysis was conducted of smelter workers with high blood Pb and urine aminolevulinic acid levels and slightly elevated values of coproporphyrin and erythrocyte protoporphyrin IX. Significant decreases of thiol groups and increases in carbonyl groups as protein degradation end products, and of nitrite were detected. Elevated rates of lipid peroxidation and rises in the activities of the antioxidant enzymes Cu-Zn superoxide dismutase and catalase were also observed. Both enzymes showed positive correlations with the blood lead levels and urine coproporphyrin, while thiol groups correlated negatively with the same indices. The genotoxic potential of lead was manifested through an increased number of DNA-damaged cells. Increased activities of serum lactate dehydrogenase isoenzymes indicated cellular damage in the lungs, kidneys, and liver. These lead-induced impairments should be taken into consideration in the assessment of Pb-related health hazards.

AB  - Lead induced oxidative cellular damage and long-term persistence of associated adverse effects increases risk of late-onset diseases. CaNa(2)EDTA chelation is known to remove contaminating metals and to reduce free radical production. The objective was to investigate the impact of chelation therapy on modulation of lead induced cellular damage, restoration of altered enzyme activities and lipid homeostasis in peripheral blood of workers exposed to lead, by comparing the selected biomarkers obtained prior and after five-day CaNa(2)EDTA chelation intervention. The group of smelting factory workers diagnosed with lead intoxication and current lead exposure 5.8 +/- 1.2 years were administered five-day CaNa(2)EDTA chelation. Elevated baseline activity of antioxidant enzymes Cu, Zn-SOD and CAT as well as depleted thiols and increased protein degradation products-carbonyl groups and nitrites, pointing to Pb induced oxidative damage, were restored toward normal values following the treatment. Lead showed inhibitor potency on both RBC AChE and BChE in exposed workers, and chelation re-established the activity of BChE, while RBC AChE remained unaffected. Also, genotoxic effect of lead detected in peripheral blood lymphocytes was significantly decreased after therapy, exhibiting 18.9% DNA damage reduction. Administration of chelation reversed the depressed activity of serum PON 1 and significantly decreased lipid peroxidation detected by the post-chelation reduction of MDA levels. Lactate dehydrogenase LDF1-5 isoenzymes levels showed evident but no significant trend of restoring toward normal control values following chelation. CaNa(2)EDTA chelation ameliorates the alterations linked with Pb mediated oxidative stress, indicating possible benefits in reducing health risks associated with increased oxidative damage in lead exposed populations.

AB  - One of the numerous adverse manifestations following lead (Pb) exposure is production of free radicals and increased oxidative stress, which can lead to altered enyzme functioning and  degradation of structural components in organism. The objective was to investigate the effects of Pb exposure on biomarkers of oxidative stress and antioxidant defence system in 15 adult male workers after occupational exposure to lead versus unexposed healthy controls. The impact of Pb on oxidative stress parameters was evaluated by measuring blood and urinary Pb concentrations, plasma levels of antioxidant enzymes catalase (CAT), superoxide dismutase (SOD), level of malondialdehyde (MDA) as the lipid peroxidation indicator, concentrations of carbonyl groups, plasma protein thiols and nitrites as biomarkers of protein oxidative modification. The results of MDA concentration revealed increased lipid peroxidation (P < 0.001), while the rise of protein carbonyl and nitrite levels (P < 0.001, P < 0.006, respectively) and decrease of plasma thiols (P < 0.001) indicated significant protein damage in Pb exposed workers, compared to unexposed controls. Increased activity of antioxidant enzymes SOD and CAT (P < 0.001) was also determined in exposed group. Elevated blood lead levels showed strong  positive correlation (r=0.809, P < 0.001) with increased CAT concentration. Our findings indicate that Pb promotes oxidative damage in exposed subjects, and that increased lead content can affect the activity of antioxidant enzymes. Considering that oxidative stress has been recognized in etiology of many diseases, future explorations on impact of these changes in populations occupationally exposed to lead are suggested.
