Influence of the delta-aminolevulinic acid dehydratase (ALAD) polymorphism on biomarkers of lead exposure in Turkish storage battery manufacturing workers.

Background: The relationship between delta-aminolevulinic acid dehydratase polymorphism (ALAD) and biomarkers of exposure was investigated in Turkish lead workers in this study.

Methods: Seventy two male lead battery manufacturing workers were selected for the study. Blood lead (BPb) and urinary lead (UPb) concentrations were determined by atomic absorption spectrometry.

Neurotoxic effects of acute and subacute formaldehyde exposures in mice.

In this study, the effects of acute and subacute formaldehyde (FA) exposures on spontaneous locomotor activity (SLMA), wet dog shake (WDS) behavior and pentylenetetrazole (PTZ) induced seizures were evaluated in Balb/C mice. SLMA was concentration dependently reduced after acute FA exposures at 1.8, 3.
