Naringin in cholestatic liver ischemia-reperfusion injury

To evaluate the potential protective effects of naringin on liver by oxidative parameters and signal peptide-CUB-EGF-like domain-containing protein (SCUBE)-1 and 2 in an experimental cholestatic liver ischemia reperfusion (IR) model.

Twenty-four female rats were divided into three groups; sham, control, and treatment. Groups 2 and 3 underwent bile duct ligation, and one week later, 45 min of ischemia and 1 hour of relaparotomy and reperfusion were performed. To the treatment group, naringin was administered through relaparotomy. Liver tissue and blood samples were taken. Alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), total bilirubin (TBIL), direct bilirubin (DBIL), ischemia-modified albumin (IMA), SCUBE-1, SCUBE-2, total antioxidant status (TAS), and total oxidant status (TOS) levels were also examined.

Serum ALT, AST, ALP, TBIL, DBIL, and IMA levels were higher in groups 2 and 3. There was no significant difference in terms of SCUBE-1 and 2 levels (p > 0.05). TAS was the highest in group 3, and TOS was the highest in group 2 and lower in group 3. In histopathological analysis, all parameters were statistically significant between group 3 and the other groups (p < 0.05).

Naringin has promising results in the treatment of experimental IR injury in cholestatic liver due to its antioxidant effects. We think that it can be used in clinical studies after more comprehensive studies investigating its effects on IR damage in cholestatic liver.
