Resumen
This work aimed to evaluate the effects of the consumption of two commercial conjugated linoleic acid (CLA) mixtures on lipid content and liver histology of healthy rats. The investigation was carried out using thirty rats divided into three groups: C (control), AE (AdvantEdge®CLA), and CO (CLA One®). The concentration of CLA was 2% of feed consumption, and the animals were supplemented daily for 42 days. The total lipid content of the liver was determined, and the histology of the organ was examined by Transmission Electronic Microscopy. The results of total liver lipid contents did not exhibit significant differences between the groups. With regard to hepatic histology, it was observed that although fat globules were visibly present in higher numbers and bigger size in the CLA groups, the organ histology was considered normal since both cytoplasm and organelles showed integrity. It was concluded that even though liver microscopic images indicated the presence of fat globules in the liver, from a statistical point of view, the supplementation for 42 days did not bring about lipid accumulation, nor did it alter hepatic histology. 31 1 141 146 Adams, L.A., Angulo, P., Lindor, K.D., Nonalcoholic fatty liver disease (2005) Canadian Medical Association Journal, 172 (7), pp. 899-905 Akbiyik, F., Ligand-induced expression of peroxissome proliferators activated receptor α and activation of fatty oxidation enzymes in fatty liver (2004) European Journal of Clinical Investigation, 34 (6), pp. 429-435 Akyüz, F., What is the best indicator for evaluating treatment response in nonalcoholic fatty liver disease: Histology or aminotransferase levels?
