Abstract

The objective of the present study was to investigate the effect a prolonged and high of sodium fluoride intake on liver metabolism in ovine. The trial involved 12 Texel x Ile de France animals, which were divided into two equal groups. The control group was treated daily with iodized salt (5 g NaCl/animal + 0.2 ppm I/kg dry matter) and the experimental group, with received the same iodized salt added of sodium fluoride (4.7 mg F/kg body weight) for 150 days. Blood samples were collected on days 60, 90, 120 and 150 of the treatment. Besides, on same days and with samples collected also at time zero, animals were placed in metabolic cages for a 24-h collection of urine samples. After animals were euthanized, a liver sample was collected for histological analysis. Fluoride concentrations in the serum and urine were increased in the experimental group. No statistical differences were observed in total protein, albumin and total cholesterol serum concentrations, and in the activities of the enzymes gamma glutamyl transferase and aspartate aminotransferase. No changes were observed in the histological analysis of the liver. The administration of sodium fluoride in the dose used and during the period analyzed in the present study does not lead to hepatotoxicity.
