The aim of present study is to investigate the role of 6-gingerol in ameliorating the renal injury in streptozotocin (STZ)-induced diabetic rats. The diabetes was induced by using a single dose of freshly prepared STZ (55 mg/kg body weight) intraperitoneally which causes the degeneration of pancreatic Langerhans isletβ-cells. The diabetic rats were treated with oral gavage of 6-gingerol (10 mg/kg b.w.). The treatment plan was continued for 8 weeks successively and the body weight and fasting blood glucose levels were weekly checked. The biochemical parameters like lipid profile, kidney profile, antioxidant enzyme levels, lipid peroxidation and anti-inflammatory marker levels were investigated after the treatment plant. The pathological condition of kidneys was examined by haematoxylin-eosin (H&E) staining besides this analysis of NF-B protein expression by immuno-histochemistry was performed. Some of the major parameters in diabetes control vs. normal control were reported as fasting blood glucose (234± 10 vs. 102 ± 8 mg/dL), serum creatinine (109.7 ± 7.2 vs. 78.9 ± 4.5 μmol/L) and urea (39.9 ± 1.8 vs. 18.6 mg/dL), lipid profile levels were significantly enhanced in diabetic rats. Moreover, diabetic rats were marked with decreased antioxidant enzyme levels and increased inflammatory markers. Treatment with 6-gingerol significantly restored the fasting blood glucose level, hyperlipidaemia,() and inflammatory marker levels, NF-B protein expression and augmented the antioxidant enzyme levels in the kidneys of diabetic rats. The kidney damage was significantly normalized by the treatment of 6-gingerol and it provides an evidence that this novel compound plays a significant role in the protection of kidney damage. These findings demonstrate that 6-gingerol reduces lipid parameters, inflammation and oxidative stress in diabetic rats, thereby inhibiting the renal damage. Our results demonstrate that use of 6-gingerol could be a novel therapeutic approach to prevent the kidney damage associated with the diabetes mellitus.
