- چکیده:
- چکیده انگلیسی: Background: Although studies are available on lipid peroxidation products and the antioxidant status in experimental animals, a detailed report on human exposed to diesel combustion nanoparticles is meagre. We aimed to study the variation in oxidative stress markers among exposures.
Method:A cross-sectional study during the period between 2015-2017 was conducted among 500 male garage workers of age group 25-40 years with history of exposure for 6-8 hrs a day without using any protective aids during work, for 6-12 years and 300 controls, who live in hilly areas where they were sparsely exposed. Serum oxidative stress markers were estimated and compared.
Results:A significant variation was observed among the oxidative stress markers in exposures with surge in melanaldehyde (MDA) and reduction in superoxide dismutase (SOD) and catalase (CAT).
Conclusion:Unprotected exposure to diesel combustion products induces oxidative stress which can alter recordable change among the markers. Oxidative stress, being the route cause for cell damage, can be marked in the initial stages and is a good biomonitoring factor in primary care.- انتشار مقاله: 30-10-1396

- چکیده:
- چکیده انگلیسی: Background:Several studies have reported the toxicological implications of inhalation of petroleum hydrocarbon fumes in animal models. But, there is certainly little or no documentation of the exposure to petroleum hydrocarbon fuel on oxidative stress levels in humans, unlike the pulmonary physiology. The present study was carried out to evaluate the effects of constituents of the hydrocarbon fuels on oxidative stress levels of the petrol fillers and tanker drivers.
Methods: The study involved 165 males divided into three groups were the petrol fillers, tanker drivers and the controls. Case control data set was established wherein the control subjects are not exposed to hydrocarbon fuels with similar age. Serum samples of the subjects were collected and subjected for various biochemical assays. The enzymatic antioxidants such as superoxide dismutase, malondialdehyde a byproduct of lipid peroxidation and total antioxidant capacity of the individuals along with non-enzymatic antioxidant Vitamin A was estimated.
Results: The results showed a no significant differences for age, body mass index, superoxide dismutase and levels of Malondialdehyde and total antioxidant capacity. But on the other hand, there is significant changes observed for total antioxidant capacity and vitamin A when exposed group is compared with control subject.
Conclusion: It is evidential from the present study that prolonged exposure to petroleum hydrocarbon fumes leads to an increase in their oxidative stress in turn resulting broad spectrum of diseases. Hence, there is a raised need for public awareness about the health hazards in order to enable petrol attendants.- انتشار مقاله: 29-09-1395
