Background Fluoride is a well-determined nonbiodegradable and moderate pollutant, which at high levels causes serious health problems. Aim The present study was designed to investigate the histopathological changes in liver as a result of exposure to sodium fluoride in albino rats and the possible therapeutic effect of both vitamins E and C. Materials and methods Eighteen adult albino mice were divided into three groups (six rats per each group). The first group served as control. The second group was treated with 3.6 mg/kg body weight sodium fluoride for 30 days, and the third group received 3.6 mg/kg body weight of sodium fluoride for 30 days followed by vitamins E and C for the next 13 days. At the end of the treatment period, the animals were sacrificed by means of cervical dislocation and the liver was dissected out. Blood samples were taken for the assessment of serum glutamic-pyruvic transaminase and serum glutamic oxaloacetic transaminase. Results Liver tissue was cleared and used for assessing the histopathological changes. Liver tissue homogenate was used for the assessment of malondialdehyde and glutathione peroxidase levels. The histopathological results in the present study indicated that exposure to sodium fluoride for 30 days caused degenerative changes in the liver. Light microscopic examination revealed the degenerative changes in the liver, such as disorganization of the cell plates, dilation of the central vein, pyknotic nucleus, ballooned hepatocytes and hepatocytes with empty nuclei, and disturbed mucopolysaccharide metabolism in liver cells. Biochemical examination revealed elevated serum glutamic-pyruvic transaminase, serum glutamic oxaloacetic transaminase, and malondialdehyde and decreased glutathione peroxidase level. Conclusion Administration of vitamins E and C during the first 13 days of the recovery period of sodium fluoride intoxication revealed minimal improvement, which was detected at the biochemical and metabolic level.
