The influence of beta-carotene on homocysteine level and oxidative stress in lead-exposed workers.
BACKGROUND Oxidative stress is involved in lead toxicity. This suggests that some antioxidants may play a role in the treatment of lead poisoning. In the light of this, the aim of the study was to determine whether beta-carotene administration reduces oxidative stress and homocysteine level in workers chronically exposed to lead. MATERIAL AND METHODS The exposed population included healthy ma...
متن کاملThe Relationship between Blood Lead Level and Neuro-psychological and Hematological Findings in Lead-Exposed Workers of Battery Industry
Background: Hematological effects and digestive and neuro-psychological signs and symptoms are some manifestations of lead toxicity. However, there are conflicting reports of their prevalence among lead exposed workers and their relationship with blood lead levels (BLL). This case- control study assessed the relationship between BLL and hematological indexes and digestive (abdominal colic, ir...
متن کاملModifications of the sympathetic skin response in workers chronically exposed to lead.
The long-term effects of low-level lead intoxication are not known. The sympathetic skin response (SSR) was evaluated in a group of 60 former workers of a primary lead smelter, located in Santo Amaro, BA, Brazil. The individuals participating in the study were submitted to a clinical-epidemiological evaluation including questions related to potential risk factors for intoxication, complaints re...
متن کاملCorrelation between plasma 5-aminolevulinic acid concentrations and indicators of oxidative stress in lead-exposed workers.
5-Aminolevulinic acid (ALA), a heme precursor accumulated in acute intermittent porphyria and lead poisoning, undergoes metal-catalyzed aerobic oxidation at physiological pH to yield reactive free radical species (O2., HO., and ALA.). We analyzed the relationships between plasma ALA concentrations, blood concentrations of lead, protoporphyrin IX (PP-IX), superoxide dismutase (SOD), and methemog...
