Objective: Ginger is a strong antioxidant and long-term treatment of streptozotocin (STZ)-diabetic animals, and it has been shown to reduce oxidative stress. Prevalence oxidative stress among urban life and changes in antioxidant capacity are considered asplay an important role in the pathogenesis of chronic diabetes mellitus.
Materials and Methods: Wistar male rat (n = 40) were divided into three groups, control group (n = 10) and Ginger Quercetin group that received 100 mg/kg (gavage), (n = 10), and diabetic group, which received 55 mg/kg intra peritoneal (IP) STZ (n = 20), which was subdivided to two groups of 10; STZ group and treatment group. Treatment group received 55 mg/kg (IP) STZ plus100 mg/kg ginger, daily for, 8 weeks, respectively; however, the control group just received an equal volume of distilled water daily (IP). Diabetes was induced by a single (IP) injection of STZ (55 mg/kg). Animals were kept in standard condition. In 28 day after inducing diabetic 5 cc blood were collected for total antioxidant capacity, malondialdehyde and oxidized low density lipoprotein levels and kidney tissues of rat in whole groups were removed then prepared for apoptosis analysis by terminal deoxynucleotidyl transferase mediated dUTP nick end labeling assay (TUNEL) method.
Results: Apoptotic cells significantly decreased in group that has received 100 mg/kg ginger (P < 0.05) in comparison to experimental groups (P < 0.05).
Conclusion: Since in our study 100 mg/kg ginger have significantly preventive effect on kidney cells damages by reducing number of apoptotic cells in kidney and hence it seems that using it can be effective for treatment in diabetic rat.
