Perflubron emulsion delays blood transfusions in orthopedic surgery. European Perflubron Emulsion Study Group.

Background: Fluorocarbon emulsions have been proposed as temporary artificial oxygen carriers. The aim of the present study is to compare the effectiveness of perflubron emulsion with the effectiveness of autologous blood or colloid infusion for reversal of physiologic transfusion triggers.

Methods: A multinational, multicenter, randomized, controlled, single-blind, parallel group study was performed in 147 orthopedic patients.

In vivo metformin treatment ameliorates insulin resistance: evidence for potentiation of insulin-induced translocation and increased functional activity of glucose transporters in obese (fa/fa) Zucker rat adipocytes.

To examine the cellular mechanism of the antihyperglycemic action of in vivo metformin (M) we used an animal model of severe insulin resistance, the genetically obese (fa/fa) Zucker rat. The animals were treated with or without M (250 mg/kg.day) which was supplied with the drinking water.
