We have evaluated current knowledge on relations between environmental and occupational exposure to lead with a strong emphasis on cardiovascular disease risk factors, such as the influence of lead compounds on lipid disturbances and arterial blood pressure. In addition, "novel" biochemical and vascular risk factors for cardiovascular diseases were(More)
BACKGROUND The significance of heavy metals in pathogenesis of the circulatory system diseases remains unresolved. The aim of the study was to evaluate electrocardiographic changes in workers occupationally exposed to lead without clinical presentation of cardiac involvement. METHODS A group of 60 smelters and refiners and 45 healthy men, as a control(More)
This study aimed at determining the relationship between environmental exposure to lead (Pb) and cadmium (Cd) and blood selenium (Se) concentration in randomly selected population of children inhabiting the industrial regions of Silesian Voivodship, Poland. The study was conducted on a group of consecutive randomly selected 349 children aged below 15 years(More)
UNLABELLED This report was intended to evaluate the effect of cigarette smoke on heart rate variability (HRV) in patients with arterial hypertension (AH). 223 individuals were qalified to the studies. The following groups of patients not suffering from other disease which may affect HRV were delineated: 1 - patients with AH (n=145); 2 - patients without AH(More)
PURPOSE The aim of the study was to evaluate echocardiographic changes in workers occupationally exposed to low doses of lead. METHODS We enrolled 63 men occupationally exposed to lead into the study (group I). Unexposed group consisted of 49 healthy men (group II). Blood lead concentration (Pb-B) and blood zinc protoporphyrin concentration (ZnPP) were(More)
UNLABELLED The aim of this study was to find a relationship between polymorphisms of ALAD rs1805313, rs222808, rs1139488, VDR FokI and HFE C282Y and H63D and basic toxicological parameters (lead and ZnPP blood concentration) in people occupationally exposed to lead. We collected data of 101 workers (age 25-63 years) directly exposed to lead. The(More)
The aim of the study was to examine endothelial function in workers occupationally exposed to lead by means of FMD (flow-mediated dilatation). 44 men professionally exposed to lead, smelters and refiners, employees working at copper smelter and control group of 41 healthy men were enrolled into the study. Within the group of men occupationally exposed to(More)
UNLABELLED Lead, cadmium and arsenic represent well recognized toxic agents which in a specific manner disturb function of cardiovascular system. Cystatin C has been accepted to be a significant prognostic factor for cardiovascular diseases. The study aimed at defining relationship between occupational exposure to lead, cadmium and arsenic on one hand and(More)
Occupational exposure to lead may cause an increase in blood pressure. The aim of the study was to estimate the effect of occupational exposure to lead on selected parameters of ambulatory blood pressure monitoring (ABPM) and structural changes in carotid arteries. The study included 33 normotensive men occupationally exposed to lead and 39 unexposed men(More)
The study aimed at defining the relationship between blood selenium concentration (Se-B) and levels of oxidative stress and antioxidative capacity in healthy children. The studies were conducted on 337 children (mean age: 8.53±1.92 years). The groups of individuals with Se-B <1st quartile (group I, Se-B<70μg/L), with Se-B fitting the range of 1st quartile(More)
