Abstract:

PURPOSE: Hepatic ischemia-reperfusion (IR) injury is a serious complication of many clinical conditions, which may lead to liver or multiple organ failure. Hyperoside, a flavonoid compound, has been reported to protect against myocardial and cerebral injury induced by IR. This study aimed to investigate the protective effects of hyperoside on hepatic IR injury in rats.

METHODS: Using the 70% hepatic IR injury model, we divided 32 male Wistar rats into 4 groups (n = 8): sham-operated, IR+saline (saline/p.o.), IR+vehicle (carboxy methyl cellulose/p.o.), and IR+hyperoside (50 mg/kg/d/p.o.). At 24 hours after reperfusion, blood and liver tissue were collected. The effects of hyperoside on hepatic IR injury were assessed through tests of serum transaminase, hepatic histopathology, and measurement of markers of oxidative stress and apoptosis.

RESULTS: Pretreatment with hyperoside protected the liver from IR injury by a reduction in serum aspartate aminotransferase/alanine aminotransferase levels and a decrease in the severity of histologic changes. Hyperoside treatment also decreased the activity of malondialdehyde, increased the activities of superoxide dismutase and glutathione peroxidase, up-regulated the expression of heme oxygenase 1 and NAD(P)H:quinone oxidoreductase 1, and reduced the apoptotic index after IR injury. A decrease in the expression of caspase-3 and an increase in the ratio of B cell lymphoma 2 to B cell lymphoma 2-associated X also were observed.

CONCLUSION: Hyperoside has a protective effect on hepatic IR injury in rats, which may be due to its antioxidant and antiapoptotic properties.
