Furan-induced cardiotoxicity in diabetic rats and protective role of lycopene

J Food Biochem. 2019 Mar;43(3):e12738. doi: 10.1111/jfbc.12738. Epub 2018 Dec 2.


The objective of this current study is to search the impacts of furan and lycopene on a diabetic rat's heart. Diabetes increases prevalence with a sedentary lifestyle and obesity. Furan, a carcinogen, was detected in foods that had undergone thermal treatment. Two groups were formed, such as: the control and diabetic groups. Diabetic groups fall into four allocated groups: control, lycopene, furan, and furan + lycopene. The changes in malondialdehide levels, antioxidant enzymes' activities, and histopathology of the heart were pointed out. We observed that the changes in both the MDA level and the antioxidant enzymes' activities were due to diabetes. Furan-induced increment in MDA levels, but GST, CAT, SOD, and GPx activities showed a decrease. Lycopene influenced these changes positively. In terms of the pathological studies, changes were also observed in diabetic rats. The histological damage in the diabetic furan groups was found to be very serious. Lycopene was protective against furan that caused histopathological changes. Diabetes and furan resulted into heart damages in rats and lycopene showed preventive effects. But this was not a complete protection. PRACTICAL APPLICATIONS: Furan by product of chlorinated chemical compounds production and chemical processes including combustion, are virtually ubiquitous in the environment. Because of this, furan occur potential risk for human health. Furan is known to exist at higher levels in fatty foods, such as full-fat milk and dairy products, meat and eggs. They can accumulate in the fatty tissues of animals and humans. Diabetes increase in the prevalence of a sedentary lifestyle and obesity. Diabetes with furan-induced cardiotoxicity. Foods should not be heated over and over again, especially diabetic heart patients should stay away from this situation.

Keywords: furan; heart; histopathology; lipid peroxidation; lycopene.
