Diesel Oil Vapor Inhalation: Risk Factor for Heart Attack

Abstract

The studies show that breathing diesel oil vapor impose serious health damage on body systems.. The main aim of this study was to determine the effects of diesel oil vapor inhalation on serum levels of cardiac troponin in male rats. In our study male Wistar rats were randomly divided into control and groups exposed to diesel oil vapor for 1, 4 or 8h/day of 5 rats in each group. After 8 weeks, blood samples were obtained using cardiac puncture method. Following serum preparation, level of cardiac troponin was measured using immunoassay method. Data were statistically analyzed and compared between groups using ANOVA. The results indicated that serum level of cardiac troponin increased in rats exposed to diesel oil vapor for 4 and 8h/day compared to control rats (P<0.001 and P<0.05, respectively). Our findings show that exposure to diesel vapor for long period of time enhances serum cardiac troponin level which may indicate damage to heart.
