Effect of breviscapine against hepatic ischemia reperfusion injury
2016
Abstract Background Breviscapine is an active ingredient extracted from traditional Chinese medicine Erigeron breviscapus . The purpose of this study was to investigate the effect of breviscapine injection on hepatic ischemia and/or reperfusion injury. Methods Forty rats were randomly divided into five groups ( n = 8): Sham group, Ischemia reperfusion 1 (I/R1) + normal saline (NS) group, I/R1 + breviscapine (Bre), I/R2 + NS group, and I/R2 + Bre group. Group1 and group2 represent ischemia time for 10 min and 30 min, respectively. Breviscapine or normal saline was administered to rats (single dose of 10 mg/Kg, intravenously) 30 min before hepatic ischemia. Serum transaminases, histopathologic changes, malondialdehyde (MDA), and superoxide dismutase (SOD) in liver tissues were evaluated. The expression level of mitochondrial fusion 2 (Mfn2) was also investigated. Results After 24-h reperfusion, based on the histopathologic analysis, compared with NS control group, the liver function was improved in breviscapine group. Liver enzymes aspartate and alanine aminotransferase levels were significantly lower in the I/R + Bre group, when compared with the I/R + NS group. Pretreatment with breviscapine reduced MDA level ( P Conclusions Breviscapine preconditioning attenuates liver ischemia reperfusion injury via inhibiting liver oxidative stress reaction. The protective mechanism probably inhibits Mfn2 protein and mRNA expression.
