OBJECTIVE: We aimed to investigate the protective potential of pomegranate extract on the liver and remote organs in rats with obstructive jaundice.
MATERIALS AND METHODS: The rats were split into 4 groups. In Group 1 (G1) (sham group) rats, the common bile duct was mobilized without any ligation. Group 2 (G2) received a combination of the sham operation and synchronous treatment with pomegranate. Group 3 (G3) received common bile duct ligation (CBDL). Group 4 (G4) were subjected to CBDL and treatment with pomegranate. After 8 days, we measured total oxidative status (TOS) and antioxidant capacity in the rats' liver tissue and remote organs, and evaluated blood levels of malondialdehyde and total antioxidant capacity (TAC).
RESULTS: G3 rats showed significantly raised malondialdehyde level as compared to G1 rats (p<0.001). Following the pomegranate therapy, a decrease in malondialdehyde was observed (p = 0.015). TAC levels were significantly raised in the G3 rats compared to the G1 rats (p = 0.004). TAC levels dropped after pomegranate therapy (p = 0.011). CBDL caused elevated TOS levels in the liver and remote organs, with a statistically significant increase in the lung tissue (p = 0.002). TOS levels in the CBDL groups decreased after pomegranate treatment (p<0.001).
CONCLUSIONS: This study reveals the marked protective effect of pomegranate on the liver and remote organs in obstructive jaundice.
