Exploring the correlation between environmental pesticide exposure and antioxidant level in recently diagnosed cancer patients

Abstract

Aim: Within biological systems thiol and ascorbic acid are important antioxidant that play roles in the antioxidant defense systems. In this study, we investigated the correlation between environmental pesticide exposure and antioxidant level in recently diagnosed cancer patients. Methodology: Blood samples were collected from 87 participants (48 male and 39 female) including control, gallbladder, blood, and oral cancer patients. Serum total thiol content and antioxidant ascorbic acid levels were measured by biochemical method. We also examined whether there is any correlation between the plasma thiol content and ascorbic acid content in cancer prevention. Results: Analysis indicated that most of the cancer patients belonged to middle age and were mostly non-vegetarian. In the present study, it was found that the total thiol content of cancer pateints was high, while the ascorbic acid content was low in cancer patients as compared to control indicating the role of oxidative stress in cancer development. Interpretation: The present study suggests that pesticide exposure may increase the total thiol content and negatively impact ascorbic acid content in cancer patients.
