Liver function after hepatic ischemia-reperfusion (I/R) injury and partial liver resection (PHx) is influenced by the extent of PHx, hepatocellular damage, and liver regeneration. This study investigates the effect of minor PHx with increasing degrees of I/R-induced damage on postoperative liver function parameters and compares the indocyanine green (ICG) clearance test with (99m)Tc-mebrofenin hepatobiliary scintigraphy (HBS) for quantitative measurement of hepatic function in a standardized rat model. ⋯ The specific impact of 30% PHx combined with progressive ischemia times is different for each liver function test. Albeit (99m)Tc-mebrofenin HBS and the ICG clearance test provide complementary quantitative information to biochemical parameters, they only quantify one or two components of liver function. ICG and (99m)Tc-mebrofenin uptake profiles differed significantly, suggesting that the specific hepatic transporters may be distinct.

Histologic type predicts survival in patients with retroperitoneal soft tissue sarcoma.
Histologic grade, completeness of resection, and presence of metastases are traditionally regarded as the primary factors in predicting survival for retroperitoneal soft tissue sarcoma (RPSTS). We sought to examine the importance of histologic type as a prognostic factor among patients with RPSTS. ⋯ Histologic type is an important predictor of survival in RPSTS.

The antioxidant properties of propofol have been shown to improve ischemia/reperfusion injury. We investigated whether anesthesia with propofol can ameliorate remote lung injury induced by intestinal ischemia-reperfusion (IIR). ⋯ Using propofol to induce and maintain anesthesia efficiently prevented IIR-induced lung injury. Systemic antioxidant protection, improvement of intestinal injury, inhibition of the inflammatory response, and preservation of the alveolar-capillary permeability seem to be crucial mediating mechanisms for this simple and clinically relevant intervention.
