BACKGROUND Given the increasing number of lead poisoning in opioids users and since no study has been conducted so far to review lead poisoning in methamphetamine (crystal) users, this study aimed to investigate blood lead level in methamphetamine addicts. METHODS This study was conducted on 20 patients with methamphetamine poisoning and their blood lead level was measured. The subjects were ...

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...

In Palestine, chronic exposure to lead has not been adequately addressed as a problem for children. To assess the exposure of Palestinian schoolchildren, we surveyed blood lead levels in 3 schools in Nablus city and collected demographic and clinical data. Blood samples were collected from 178 children (140 boys, 38 girls), age range 6-8 years. The overall mean blood lead level was 3.2 (SD 2.4)...

The association between blood lead level and dental caries was evaluated in cross-sectional analyses of baseline data for 543 children 6-10 years old screened for enrollment in the Children's Amalgam Trial, a study designed to assess potential health effects of mercury in silver fillings. Approximately half of the children were recruited from an urban setting (Boston/Cambridge, MA, USA) and app...

BACKGROUND Lead is a pollutant with numerous adverse effects on health. Since it can affect blood pressure, peripheral blood vessels, and the heart, the present study aimed to evaluate the relation between occupational exposure to lead and blood pressure. MATERIALS AND METHODS This cross-sectional study included male individuals working in battery firms in Isfahan. A questionnaire covering de...

Background: Breast milk can be a source of toxic material, along with the transfer of nutrients needed for infant growth. This study was conducted to measure the level of lead in maternal and neonatal blood and breast milk in Tehran, Iran.Methods: In this cross-sectional study, 150 mothers and their infants were studied. Samples of maternal blood, fetal umbilical cord blood, breast milk, ...

Lead levels were measured by atomic absorption spectrophotometry in umbilical cord blood samples of 205 consecutively born neonates and venous blood in 62 of the mothers. The mean (+/- SD) cord blood lead level was 4.7 +/- 12.1 microg/dL. In the sub sample of 62 mother-baby pairs, the mean (+/- SD) cord blood lead levels were 1.6 +/- 2.5 microg/dL and 2.0 +/- 2.1 microg/dL, respectively. Accord...

Some dietary factors could inhibit lead toxicity. The aim of this study was to evaluate the effect of dietary compounds rich in unsaturated fatty acids (FA) on blood lead level, lipid metabolism, and vascular reactivity in rats. Serum metallothionein and organs' lead level were evaluated with the aim of assessing the possible mechanism of unsaturated FA impact on blood lead level. For three mon...

INTRODUCTION Lead is a heavy metal to which people are commonly exposed. One of the possible mechanisms of tissue damages caused by this toxic metal is oxidative stress, which in turn may cause numerous pregnancy complications such as preeclampsia. The present study was conducted to determine the relationship between maternal Blood Lead Level (BLL) and preeclampsia. METHODS The present case-c...

Background: Metals such as iron, zinc, and copper are critical and necessary for the survival of all living organisms, whereas xenobiotic metals such as lead, cadmium, mercury, and arsenic have no known biologic role. Any metals in high doses can have toxic effects. The aim of this work was to evaluate the hematological changes induced by lead as a toxic metal and characterize the potential eff...
