title: Status of trace elements and antioxidants in premenopausal and postmenopausal phase of life: a comparative study.
abstract: The aim of the study was to determine the extent of free radical damage in the form of oxidative stress, the antioxidant status and correlate with trace element levels in postmenopausal females as compared to premenopausal females. Participants between the ages of 30-60 years were recruited for the study and status of antioxidant enzymes and trace metals level was determined. The serum Calcium (Ca) levels after menopause was higher than that of the premenopausal group (P<0.001). The changes in copper (Cu) and Zinc (Zn) between the groups were not significant (p>0.05). In postmenopausal women, antioxidant enzymes like superoxide dismutase (SOD) and glutathione peroxidase (GPX), catalase (CAT) significantly decreased (P<0.001) in postmenopausal women showing oxidative stress in the cells. Concentrations of vitamin-C pointed out a significant decrease (P<0.05) in postmenopausal women when compared with premenopausal women.
