Terminalia arjuna's antioxidant effect in isolated perfused kidney

Area of Science:

• Pharmacology and Toxicology
• Nephrology
• Natural Product Chemistry

Background:

• Oxidative stress is a significant factor in kidney damage.
• Standardized methods for inducing and evaluating oxidative stress in isolated organs are crucial for research.
• Terminalia arjuna is a medicinal plant with known antioxidant potential.

Purpose of the Study:

• To standardize the induction of oxidative stress using Fenton's mixture (FM) in isolated perfused rat kidneys.
• To evaluate the antioxidant effects of hydroalcoholic extract of Terminalia arjuna bark on these oxidatively stressed kidneys.
• To determine the optimal dosage of Terminalia arjuna extract for antioxidant activity.

Main Methods:

• Isolated perfused rat kidney model was utilized.
• Oxidative stress was induced using Fenton's mixture (FM).
• The effects of Terminalia arjuna bark extract at 250 and 500 mg/kg were assessed on biochemical markers.

Main Results:

• Induction of oxidative stress significantly increased lipid peroxidation and liver enzymes (GPT, GOT).
• Treatment with Terminalia arjuna extract dose-dependently reduced oxidative stress markers.
• Enzyme levels were maintained near normal levels following extract perfusion, indicating a protective effect.

Conclusions:

• The study successfully standardized oxidative stress induction in isolated perfused rat kidneys.
• Hydroalcoholic extract of Terminalia arjuna bark exhibits significant antioxidant potential.
• Terminalia arjuna extract demonstrates protective effects against oxidative damage in the kidney at tested dosages.
