The correlation between the blood lead (B-Pb ) levels and the values of blood pressure in hypertensive patients was investigated. Moreover, plasma levels of nitric oxide (NO), total antioxidants (TAOX) and malondialdehyde (MDA) were detected to investigate the correlations between the measured parameters and B-Pb levels in hypertensive patients. Fifty-five hypertensive patients were compared wi...

Chronic lead exposure has been associated with elevated blood pressure in epidemiological studies. It is not known whether the previously observed relation between blood lead and hypertension persists after significant reductions have been made in environmental lead contamination. We examined the relation between blood lead levels and blood pressure in a representative sample of 14 952 whites a...

background patients, who survived from shotgun injuries, often have some retained lead pellets in their bodies. several cases of lead toxicity have been reported regarding these patients. objectives this study seeks to compare the serum lead level in patients who have retained lead pellets in their bodies with the control group. patients and methods in this case-control study, we gathered the s...

Although recent data continue to demonstrate a decline in the prevalence of elevated blood lead levels (BLLs) in children, lead remains a common, preventable, environmental health threat. Because recent epidemiologic data have shown that lead exposure is still common in certain communities in the United States, the Centers for Disease Control and Prevention recently issued new guidelines endors...

In Brazil there is no systematic evaluation to access blood lead levels (BLL) in the general population and few studies with adults have been published. The aim of this study was to examine the socioeconomic, environmental, and lifestyle determinants of BLL in the adult Brazilian population. In total, 959 adults, aged 40 years or more, were randomly selected in a city in southern Brazil. Inform...

background and objectives: tetanus and diphtheria are vaccine-preventable, infectious diseases with significant morbidity and mortality. immunization by the diphtheria and tetanus toxoid (dt) has been applied in iran for almost 50 years. however, there are very few data about the rate of immunity to these diseases in the adult population. the humoral immunity to tetanus and diphtheria among blo...

  Background :Lead elements have an adverse effect on human health. The most important complications of lead poisoning are disorders of nervous system particularly seizure .This study aimed to evaluate the blood lead levels and its association with convulsion in a group of hospitalized febrile children.   Methods : In this analytic cross-sectional study, 60 hospitalized febrile children with 1-...

abstract   background: lead toxicity is caused by ingestion, inhalation, or contact with particles or vapors containing lead. it can present with nonspecific signs and symptoms such as abdominal pain, constipation, irritability, difficulty concentrating, and anemia. in this study, we have tried to find a relationship between lead poisoning and drug abuse.   methods: in a cross sectional study, ...

INTRODUCTION Elevated blood lead levels (BLL) and malaria carry an important burden of disease in West Africa. Both diseases might cause anemia and they might entail long-term consequences for the development and the health status of the child. Albeit the significant impact of malaria on lead levels described in Nigeria, no evaluation of the effect of elevated BLL on malaria risk has been inves...
