Background: Antioxidants have essential effect on tissue regeneration after cells injury. Enhanced oxidative stress and changes in antioxidant capacity are considered to play an important role in the pathogenesis of chronic diabetes mellitus. Ginger rhizome and carrot seed are strong antioxidants and long-term treatment of Streptozotocin induced–diabetic animals with these herbs, has been shown to reduce oxidative stress.

Objective: Evaluation to treatment effect of Ginger rhizome and extract of carrot seed on nephropathy after diabetes inducement.

Methods: Wistar male rat (n=70) were allocated into seven groups, control group, carrot seed extract group, ginger group, control- Diabetic group received 55mg/kg (IP) streptozotocin (STZ), treatment diabetic group that received carrot seed extract, treatment diabetic group that received ginger and treatment diabetic group that received carrot seed extract plus ginger. Animals were kept in standard condition. In 30 day after inducing diabetes, 5ml blood were collected for analyzing of TAC and MDA levels, and kidney tissues of Rats were removed in all groups then prepared for analysis.

Results: Pathological changes in diabetic group which received carrot seed and ginger together was decreased compared to control group. The rate of serum TAC significantly increased in diabetic groups which received carrot seed and ginger together significantly in comparison to control-diabetic group (p<0.05).
