title: Combination of DFP and Taurine Counteracts the Aluminum-Induced Alterations in Oxidative Stress and ATPase in Cortex and Blood of Rats.
abstract: The study investigated the combined effect of 1,2-dimethyl-3-hydroxypyrid-4-one (DFP) and taurine on aluminum (Al) toxicity in cortex and blood of rats. The control group received 1 ml/kg/day saline solution for 8 weeks. Other animals were exposed to Al at a dose of 281.40 mg/kg/day orally for 4 weeks. Then, they were administered with 1 ml/kg/day saline solution, 400 mg/(kg·day) taurine, 13.82 mg/(kg·day) DFP, 27.44 mg/(kg·day) DFP, 400 mg/(kg·day) taurine +13.82 mg/(kg·day) DFP, and 400 mg/(kg·day) taurine +27.44 mg/(kg·day) DFP for 4 weeks. The changes in markers of oxidative stress, activities of antioxidant enzymes, and triphosphatase (ATPase) in the cortex and blood were determined. Administration of Al led to significant increase in the malondialdehyde (MDA) level and decrease in the activities of antioxidant enzymes, Na+K+-ATPase, Mg2+-ATPase, and Ca2+-ATPase in the cortex and blood, compared with the control group. DFP was observed to reverse alteration of these parameters except for Ca2+-ATPase activity. Treatment with taurine caused significant increase of GSH-Px activity and decrease of the MDA level in the cortex and serum and rise of Na+K+-ATPase in the blood. Effects of DFP combined with taurine were investigated and found to provide a more significant benefit than either drug alone. Combined intake of taurine and DFP could achieve an optimum effect of therapy for Al exposure.
