    The present study was carried out to investigate (1) the alterations in biochemical parameters, free radicals and enzyme activities induced by aluminum chloride (AlCl3) in kidney of male Swiss albino mice, and (2) the role of taurine in alleviating the nephrotoxic effects of AlCl3. Taurine plays an important role as an antioxidant and is consequently expected to protect tissues from damage caused by reactive oxygen metabolites. The animals were randomized into four groups (n=6/group). Group I was the control group. Group II received a single dose of AlCl3 (25 mg Al3+/kg b.w., ip). Group III received taurine (100 mg/kg b.w., ip) for 5 consecutive days before administration of AlCl3 (25 mg Al3+/kg b.w., ip). Group IV received taurine (100 mg/kg b.w., ip) for 5 consecutive days. 24 h following the administration of compounds, all the mice were assessed using serum and tissue homogenate biomarkers as well as the pathological evaluation. Exposure to AlCl3 led to an increased level of renal lipid peroxidation as measured by malondialdehyde (MDA), while reduced glutathione (GSH), glutathione peroxidase (GPx) and catalase (CAT) decreased. Marked elevation of blood urea and serum creatinine concentrations were also observed in AlCl3 treated mice, thereby indicating renal damage. All these factors were significantly improved by taurine pretreatment. The histological and ultrastructural observations on the kidney tissues also confirmed the renoprotective nature of taurine. Thus these results may indicate that taurine treatment protects against functional, biochemical and morphological damage in AlCl3-induced acute renal failure in mice.
