Abstract
AIM: To study the protective effect of strep-tokinase on rat liver ischemia reperfusion injury.
METHODS: Thirty-six Wistar rats were divided randomly into control group and 2 experiment groups (12 in each group). Livers from the control group were perfused with 10 mL Ringer's solution through the portal vein and stored at 4 ℃ for 24 h. Livers from the experiment group were perfused with Ringer's solution containing 7500 IU streptokinase with or without hypothermal oxygen stored at 4 ℃ for 24 h. All cold storage livers were followed by in vitro perfusion at 37 ℃ for 45 min, and stored at 4 ℃. Changes in ALT, GLDH, and activity of PNP, 5'nucleotidase and bile secretion were detected.
RESULTS: The activity of ALT, GLDH and PNP was significantly lower in the experiment groups than in the control group(P < 0.05). Bile secretion(3.7 ± 0.7 µL/g at 45 min, 9.1 ± 0.7 µL/g at 45 min vs 1.1 ± 0.9 µL/g at 45 min, P < 0.05) and 5'nucleotidase activity were significantly increased in the experiment groups compared with the control group.
CONCLUSION: Streptokinase can improve rat liver microcirculation and ischemia reperfusion injury.
