Effect of Vitamin B5 on Liver Enzyme Levels in Bile Duct Ligation Cholestatic Rat Model

Background and Objectives: Accumulation of toxic bile salts in a bile duct ligation (BDL) animal model plays a pivotal role in the induction of liver fibrosis. Vitamin B5 is an essential nutrient, which acts as a cofactor in many detoxification system enzymes. In the present research, the antifibrotic effect of vitamin B5 was investigated on liver cholestasis induced by BDL in rats. Methods: In this experimental study, 72 male Wistar rats were divided into 9 groups: Control, sham-operated, vitamin B5 (5, 50, and 100mg/kg bw), BDL, and BDL+vitamin B5 (5, 50, and 100mg/kg bw). After BDL, rats were given vitamin B5 via intragastric gavage for 28 consecutive days. At the end of the experiment, blood was collected from heart and activity of aspartate aminotransferase (AST), alanine aminotransferase (ALT), and alkaline phosphatase (ALP) enzymes, were measured. The data were analyzed using one-way ANOVA test. Results: In the BDL animals, the serum activities of AST, ALT, and ALP significantly increased (p
