Attenuation of uremia by orally feeding alpha-lipoic acid on acetaminophen induced uremic rats.

Abstract

Uremia means excess nitrogenous waste products in the blood & their toxic effects. An acute acetaminophen (paracetamol, N-acetyl p-aminophenol; APAP) overdose may result into potentially fatal hepatic and renal necrosis in humans and experimental animals. The aims of this present study were to investigate the protective effect of alpha-lipoic acid (ALA) on oxidative stress & uremia on male albino rats induced by acetaminophen. The study was performed by 24 albino male Wister strain rats which were randomly divided into four groups: Group I, control - receives normal food and water, Groups II, III & IV receive acetaminophen interperitoneally at the dose of 500 mg/kg/day for 10 days, from 11th day Groups III & IV were treated with ALA at the dose of 5 mg & 10 mg/100 g/day for 15 days, respectively. After 25 days of treatment, it was observed that there was a significant increase in plasma urea, creatinine, sodium and malondialdehyde (MDA) levels (p < 0.05) but a significant decrease in super oxide dismutase (SOD) & catalase activity & potassium level in uremic group is compared with control group & there was a significant increase in SOD & catalase (p < 0.05) & a significant decrease in serum urea, creatinine & Na and MDA (p < 0.05) in Group III & Group IV is compared with Group II & significant changes were observed in high ALA dose group. In conclusion it was observed that the ALA has nephroprotective activities by biochemical observations against acetaminophen induced uremic rats.
