The effects of Hypericum perforatum on hepatic ischemia- -reperfusion injury in rats
Background:
Ischemia-reperfusion injury (IR) is associated with a high morbidity and mortality. Several agents have been used to protect the liver after IR. We aimed to investigated the effects of the Hypericum perforatum on IR of the liver.
Methods:
A total of 62 wistar-albino male rats in 4 groups were used. Sham group (n: 8). Control group (IR, n: 18) was underwent partially liver ischemia and reperfusion (IR). Carboxymethyl cellulose group (CMC n: 18) was given 0.5 % carboxymethyl cellulose before IR for a week. Hypericum perforatum group (HP, n:18) was given 0.5 % carboxymethyl cellulose supplemental the extract of Hypericum perforatum before IR for a week. Blood and liver samples were obtained before ischemia, and 1, 2, 4 hours after the reperfusion. AST, ALT, LDH, TNF-α, IL-6, MDA and advanced oxidation protein products(AOPP) levels were determined in blood samples. Histological evaluation and tissue MDA, AOPP levels were determined.
Results:
Blood levels of ALT, TNF-α, IL-6 and MDA were significantly low in HP group compared with IR and CMC groups (p < 0.05). There was no difference between the liver injury scrores of IR and CMC groups (p > 0.05).
Conclusion:
[corrected] These results indicate that H. perforatum can protect the liver against IR. As antioxidative agent, Hypericum perforatum has both local and systemic protective effects in ischemia reperfusion injury (Tab. 1, Fig. 4, Ref. 31).
