The effect of green tea on the oxidative stress and blood glucose level of diabetic rats

Abstract EN

Green tea was reported to have an antioxidant effect.

However, few studies were found on the effect of green tea on the oxidative stress caused by diabetes mellitus.

The aim of this study was to investigate the effect of green tea on the blood levels of lipid peroxidation product-malondialdehyde, superoxide dismutase enzyme and glutathione peroxidase enzyme.

The effect of green tea on the blood glucose level of diabetic rats was also investigated.

Three groups were examined in this study; they were a control group, a diabetic group and a diabetic group who used green tea.

The blood level of malondialdehyde, superoxide dismutase enzyme and glutathione peroxidase enzyme were measured at 6 and 12 weeks after the induction of diabetes and the use of green tea.

The blood glucose levels of the three groups were also measured at 6 and 12 weeks.

The results obtained from this study showed that the use of green tea reduced the level of malondialdehyde significantly, and it caused a noticeable increase in the activity of superoxide dismutase and glutathione peroxidase enzymes.

It also clearly reduced the level of blood glucose of diabetic rats.
