Anaemia is considered a serious public health problem in Egypt, although updated population-based data are lacking. Similarly, data on prevalence and intensity of infection with intestinal parasites, which are considered one possible cause of anaemia, are available only from small, unrepresentative sample surveys. The present research was implemented on an(More)
The present study was aimed for the effects of exposure to multiple organic solvent vapors in comparison with single exposure to phenol. It included 20 workers exposed to phenol alone and 32 workers of combined exposure to phenol, benzene, toluene and methyl ethyl ketone. A control group of 30 subjects was also included. The levels of transaminases, total(More)
The aim of this study was to investigate the cytogenetic changes induced in humans exposed to styrene in a reinforced plastics plant. Blood and urine samples were collected from 18 styrene exposed workers and 18 age and sex matched control subjects from the administrative department of the same factory. Chromosome aberrations (CAs) and micronuclei (MN)(More)
The process of urbanisation taking place in most developing countries is creating favourable conditions for an increase in prevalence of infections, especially with intestinal parasites, in the marginal areas of the towns. The present study was implemented in 1996 to assess the varying prevalence and intensity of infection among young workers in urban and(More)
Styrene is a known mutagen and suspected carcinogen, used in the reinforced plastic industry. This study aims to identify the occurrence of DNA single strand breaks (SSBs) in workers exposed to styrene levels far below the recommended standards. We compared 26 exposed workers with 26 control subjects and found a significant increase in the incidence of(More)
Occupational exposure to lead fumes constitutes a serious problem in Egypt, since a considerable number of workers might be involved in its deleterious effect. The present study aimed to elucidate the effect of lead exposure on the lipoprotein pattern of exposed workers. The study has been carried out in a plant manufacturing lead batteries. It consists of(More)
The interactions between the nervous and immune systems have been recognized in the development of neurodegenerative disease. This can be exploited through detection of the immune response to autoantigens in assessing the neurotoxicity of environmental chemicals. To test this hypothesis, the following questions were addressed. a) Are autoantibodies to(More)
In a cross-sectional survey, we investigated exposure to and the presence of factors associated with anaemia, such as socioeconomic conditions, dietary habits, intestinal parasitic infections and lead among 355 young male workers (7-19 years of age) employed in private workshops. Of the total study sample, 44.5% (158 participants) were found to be anaemic.(More)
An expanded follow-up assessment of the autoantibody response to neuronal and astroglial autoantigens (NF68; NF160; NF200; MBP; GFAP) as early markers of neurotoxicity was performed in male workers exposed to lead (Pb) of a battery factory (n=50) and a matched reference group (R) of workers at a food packing plant (n=39). Mean age, years of exposure and(More)
Somatic cell mutation in human peripheral lymphocytes is one of the tools used recently in the biological monitoring of the work environment. The scope of this review was to test whether biomonitoring methods are sensitive to the presence of mercury (Hg) in the body. We used the following techniques: micronucleus frequency (MN), sister chromatid exchanges(More)
