title: Deviations in hepatic amino acid profiles of mouse following repeated hexachlorophene administration.
abstract: Effects of repeated administration of hexachlorophene (HCP) on the food consumption, body and liver weights, liver somatic indices and hepatic levels of the free amino acids and amino acid-enzyme activities have been studied. A dose-dependent reduction in body weights and food consumption and increased liver somatic indices suggested a progressive and on toward response to HCP. The concentrations of hepatic free amino acids: phenylalanine, tyrosine, leucine, isoleucine, valine, threonine, asparagine, glutamic acid and glutamine were significantly (p less than 0.001) increased while serine, glycine, taurine and alanine levels were unaffected. The aspartic acid levels showed a conspicuous decrement. The specific activity patterns of the amino acid-enzymes denoted reduced oxidation of amino acids in liver. The abnormal rise in branched chain and aromatic amino acids could be due to the reduced utilization because of the depletion of skeletal muscle mass and hepatic dysfunction in HCP intoxication. A pronounced reduction in aspartic acid levels may deserve consideration in the manifestation of hyperammonemia and neurologic symptoms in HCP intoxication.
