Study of Serum Malondialdehyde Level in Opioid and Methamphetamine Dependent Patients.
Acta Medica Iranica 2017 October
Opioid compound and methamphetamine are commonly used in drug abuse; these can disrupt the normal function of cellular and molecular systems, leading to several events such as oxidative stress, aging, apoptosis, and necrosis. Malondialdehyde (MDA) is the most important biomarker for evaluation of oxidative stress and determination of lipid peroxidation. In this study, 42 drug abusers and 22 healthy persons participated as case and control groups, respectively. MDA in volunteer sera was determined by high-performance liquid chromatography (HPLC) with fluorescence detection after pre-column derivatization using thiobarbituric acid. The analysis was performed on a ODS column by spectrofluorometer detection, operated at excitation of 515 nm and emission of 535 nm. A mixture of phosphate buffer (0.05 M, pH 6.8), containing potassium monobasic phosphate and methanol (60:40, v/v) at a flow rate of 1 ml/min, was used as the mobile phase. The retention time of MDA-TBA was 3.2 min. Our findings showed that the MDA level increased in the opioid and methamphetamine abusers when compared to the control group (P<0.05); however, no significant difference was observed between the opioid and methamphetamine groups. A state of oxidative stress during biological processes leads to lipid peroxidation, DNA damage, biomolecule dysfunctions, and many other diseases. Since it is impossible to eradicate the drug addiction, we should reduce the side effects of drug abuse, such as oxidative stress, by intake of proper nutrition and antioxidants.
