Abstract
Objectives: To study the effect of menopause associated with estrogen deficiency on lipid peroxidation products, such as malondialdehyde (MDA) with evaluation of some antioxidants like, glutathione (GSH) and its relation to lipoprotein levels in women living in Mosul City.
Design: Case-control study.
Setting: The study was carried out in Al-Salam Teaching Hospital in Mosul City, during the period from January 2008 to April 2008.
Patients and Methods: A total of 27 women aged 20–45 years were reported to be premenopausal and 42 women aged 45–60 years were recorded to be postmenopausal. Blood samples were collected for both groups. The assessments of serum malondialdehyde (MDA), glutathione (GSH), estrogen, arylesterase, calcium, total cholesterol, triglycerides (TG), low-density lipoprotein cholesterol (LDL-c), and high-density lipoprotein cholesterol (HDL-c) were done.
Results: There were significant increase in MDA level in women after menopause in comparison with premenopausal age. On the other hand, GSH, estrogen, arylesterase, and calcium levels were significantly decreased. In respect to lipids, total cholesterol, TG, and LDL-c, were significantly increased in opposite to HDL-c, in which was decreased significantly in postmenopausal women in relation to premenopausal subjects.
Conclusion: The increase of MDA and the decrease of antioxidants concentrations like gluthathione, estrogen and HDL-c in postmenopausal women could contribute to acceleration of the cellular oxidative damage.
