One cause of autism is lead contamination in pregnant women or children. We describe effect of lead ions with or without omega 3 fatty acid supplement on anodic peak currents (oxidation) measured by cyclic voltammetry in blood of groups of 5 NZ white female rabbits each, 9 times for 9 weeks. The omega compound reduced (P < 0.05) current oxidation peak of lead ions from 16.8 uA to 2.49 uA and concentration of lead ions in blood 12.138 to 0.353 mg/l. The findings suggest that omega may reduce lead ion oxidation in blood of rabbits. Keywords: Lead ions, Blood Medium, Cyclic Voltammetry, GCE, Omega3, Rabbit INTRODUCTION Lead ions can induce oxidation and creation of free radicals in human blood [1-5]. Omega-3 fatty acid inhibits lipid peroxidation in brain tissue in rats [7]. Differential pulse stripping anodic voltammetry can measure concentration of lead and cadmium ions in samples of fish [8]. Omega 3 fatty acid exhibits anti-oxidant effects in patients with kidney failure and is given to hemodialysis patients [9]. Fish meal omega fatty acids reduce oxidant stress in cardiovascular disease. [10, 11]. Recently, omega-3 polyunsaturated fatty acids was given to rats with lead acetate-induced toxicity in liver and kidney of female rats causing elevation in MDA and depletion of antioxidant enzymes in tissues confirmed by histopathological changes and DNA damage [12]. We report effect of omega 3 fatty acid on lead ion anode current peaks measured by cyclic voltammetry in blood of rabbits.
