Beryllium Induced Biochemical Alterations in Rodent Model and its Treatment with Calcium Salt of Diethylene Triamine Penta Acetic Acid with α -tocopherol

Abstract

To evaluate therapeutic efficacy of chelating agents tiron (Sodium-4,5- dihydroxy-1,3-benzene di-sulphonate) and CaNa3DTPA (Calcium tri-sodium di-ethylene tri-amine penta acetic acid) in presence of α-tocopherol against beryllium induced toxicity, adult female albino rats were exposed to beryllium nitrate for 28 days followed by therapy with tiron (471 mg/kg, ip) and CaNa3DTPA (35 mg/kg, ip) alone and in combination with α-tocopherol (25 mg/kg, po). Results revealed non-significant fall in hemoglobin and total serum protein content while significant fall in blood sugar level and activity of serum alkaline phosphatase. On the other hand, significant rise in the activity of serum transaminases and LDH was noticed after beryllium administration. Significant increase in total and esterified cholesterol was found in liver and kidney after toxicity. Significant increase in lipid peroxidation and decreased level of reduced glutathione in both the organs showed oxidative stress due to beryllium exposure. CaNa3DTPA showed moderate therapeutic efficacy; however, its effectiveness was enhanced with α-tocopherol to some extent. Tiron in combination with α-tocopherol exerted statistically more beneficial effects in reversal of beryllium induced biochemical alterations.
