Abstract

BackgroundSmoking is the act of introducing toxic substances into the body. Cigarette smoke contains chemicals that may cause several disorders, including cardiovascular disease, cancer, and chronic obstructive pulmonary disease. Toxic substances in cigarette smoke have the potential to increase free radicals, malondialdehyde (MDA) levels and to decrease endogenous antioxidant (glutathione/GSH) levels. This study aims to determine the relationship of smoking with plasma GSH and MDA levels in medical students.MethodsThis study was analytical observational with cross-sectional approach. The study was conducted from April to December 2015. The subjects in this study were medical students, consisting of 20 smokers and 20 nonsmokers. Plasma GSH and MDA levels were determined biochemically using Sigma GSH Assay Kit and Sigma MDA Assay Kit. Data was analyzed using the independent t test. ResultsThe results showed that there was no significant difference between mean GSH in smokers (1.74 ± 0.91 mmol/L) and nonsmokers (2.42 ± 1.19 µmol/L) (p=0.441). Mean smokers MDA level of 2.06 ± 1.39 nmol/mL was not significantly different compared with mean nonsmokers MDA level (1.32 ± 0.90 nmol/mL) (p=0.092).ConclusionsSmoking tends to decrease plasma GSH levels and increase plasma MDA levels in medical students. Smoking history could be evidence of oxidative stress and an impaired oxidant defense system. In particular, young smokers should quit promptly before health problems arise, so as to have the optimal benefits of cessation.

Abstract

BackgroundMaternal mortality rate is still a health problem in Indonesia. One major contributor to maternal mortality rate in Indonesia is preeclampsia. One widely accepted theory is that preeclampsia is caused by oxidative stress. Placental hypoxia or ischemia among preeclampsia patients is thought to be the cause of the formation of free radicals such as malondialdehyde (MDA), which decreases endogenous antioxidants such as glutathione (GSH). This study aims to ascertain the difference in plasma malondialdehyde and glutathione levels between healthy and preeclamptic pregnant women.MethodsThis was an observational analytic study of cross sectional design. Research subjects were 30  normal (healthy) pregnant women (NP), and 30 pre-eclamptic pregnant (PE) women. The measurement of plasma MDA and GSH levels was done at the Biochemistry and Molecular Biology laboratories, Faculty of Medicine, Sriwijaya University using Sigma-Aldrich MDA and GSH assay kits. Mann Whitney test was used to analyze the data. ResultsSubjects aged >35 years, with age of gestation >35 weeks and multipara was significantly higher in the PE group compared to the NP group (p=0.016; p=0.01 and p=0.36; respectively). MDA level was significantly higher in the PE group than in the NP group (p=0.002). In contrast, GSH level was significantly lower in the PE group than in the NP group (p=0.003).ConclusionMDA and GSH may reflect vascular complications of PE, and the ensuing increases in lipid peroxidation may play important pathogenic roles.
