Contribution of angiotensin II in hepatic ischemia /reperfusion induced lung injury: Acute versus chronic usage of captopril.

Background: Acute lung injury is one of the most popular consequences of hepatic ischemia/reperfusion (I/R) injury. Recently it was documented that renin-angiotensin system plays a key role in tissue inflammation, generation of reactive oxygen species (ROS) and tumor necrosis factor-alpha (TNF-α) (the principal liver injury mediators) during I/R.

Material And Methods: We investigated the effect of acute versus chronic usage of angiotensin converting enzyme inhibitor (captopril) on liver inflammation and lung injury caused by hepatic ischemia for 1h followed by 24h reperfusion.

Erythropoietin protects against doxorubicin-induced heart failure.

The hormone erythropoietin (EPO) has been demonstrated to have cardioprotective properties. The present study investigates the role of EPO to prevent heart failure following cancer treatment with doxorubicin [adriamycin (AD)]. Male Wistar rats (150 ± 10 g) were treated with saline (vehicle control group); with EPO, subcutaneously at 1,000 IU/kg body wt, three times per week for 4 wk (EPO group); with adriamycin, intraperitoneally at 2.
