This study aimed to evaluate the effect of supplementation of sucralose and fructose on the metabolism of adolescent rats. Eighteen male Wistar rats were divided into 3 groups: control group (GC), fructose group (GF) treated with 50 mg/kg of fructose, and sucralose group (GS) receiving 50 mg/kg of sucralose for 24 days. The weight and feed intake were measured weekly. At the end of the experiment, some biochemical parameters, histopathology of the liver and biodistribution of the radiotracer 99mTc-sodium phytate in liver and blood were analyzed. The GF showed higher body weight only in the first week compared with GS and GC (p<0.05). Histopathology and % ATI/g radiotracer 99mTc-sodium phytate in liver and blood were not different between the groups. The GF showed higher values of aspartate aminotransferase activity, bilirubin, alkaline phosphatase activity and gamma glutamyl transferase activity, compared with the other groups (GC and GS) (p<0.05). Activity of alanine aminotransferase and albumin level of GF were higher than GS (p<0.05). For other parameters, no statistical difference was observed. It was concluded that the use of fructose during the experiment was able to alter hepatic enzymes, but on the other hands, the use of sucralose caused no change.
Key words: Sucralose, fructose, adolescent rats, radiopharmaceutical.
