Subjects occupationally exposed to potential mutagens/carcinogens represent the most suitable groups for epidemiological studies aimed at assessing the risk for the individual or the offspring. Several cancer risks to humans have been detected by epidemiological studies performed in occupational settings. The epidemiology studies have been able (a) to identify specific occupations or agents associated with the risk; (b) to verify the results of experimental studies; and (c) to test the effectiveness of changes in production or preventive measures in decreasing risks. Reproductive epidemiology has suggested a risk of spontaneous abortions or of malformation in the offspring of workers exposed to some chemicals or occupations, but data are often conflicting due to methodological problems. With the aim of early assessment of risk in mind, the epidemiological use of indicators of exposure or of the early effect of exposure to genotoxic agents is increasingly applied to occupational groups. Data on the fertility and other reproductive end points in 128 women beedi rollers exposed to tobacco dust were recorded by using standard questionnaire. The exposed group were further categorized based on duration of exposure, life style, smoking and non-smoking and socio-economic status. The statistical analysis shows that the differences in the reproductive end points between the control and exposed groups were significant (P<0.05).Keywords

Shoe manufacturing is an age-old profession in India. The genotoxic potential of organic solvents in cultured peripheral lymphocytes has been investigated on 62 male workers in a leather shoe factory located at IDA, Nacharam in Ranga Reddy district of Andhra Pradesh by using one of the recommended cytogenetic biomarkers. The blood samples were collected from male workers and 42 age matched controls. Analysis of sister chromatid exchanges in human peripheral lymphocytes was carried out in control and exposed groups. A significant increase in the percentage of SCEs was observed as compared to control. Thus, the study clearly reveals the mutagenic effect of organic solvents on human beings.Keywords

The protective effects of curcumin in chromium induced cytotoxicity was evaluated in in vivo animal model using analysis of chromosomal aberrations in somatic cells of mice. Three doses of curcumin were selected for modulation and given to animals after priming with chromium. The animals ware sacrificed 48hr after the treatment and slides were prepared. A significant decrease was observed in the percentage of chromosomal aberrations when animals were primed with curcumin. The present results clearly indicate the protective nature of curcumin against heavy metal genotoxicity.Keywords
