BACKGROUND Vascular occlusion to prevent haemorrhage during liver resection causes ischaemia-reperfusion (IR) injury. Insights into the mechanisms of IR injury gathered from experimental models have contributed to the development of therapeutic approaches, some of which have already been tested in randomized clinical trials. METHODS The review was based(More)
The extent of callus formation about a bone fracture depends on the rigidity of fracture fixation. The mechanism that converts the mechanical stimulus into the biologic response is unknown. On the basis of existing literature, an attempt has been made to define a model that explains this mechanobiologic transduction. Once integrity of the bone has been(More)
Mechanical conditions at the fracture line determine the mode of fracture healing (osteonal versus non-osteonal bone union). The aim of this study was to investigate the influence of differing degrees of fracture stability on the time course of chondrogenesis, enchondral ossification and immigration of macrophages into the fracture callus. Using a fracture(More)
The aim of the study was to investigate the long-term effects of postoperative immobilization as opposed to mobilization on the biomechanical attributes of healing Achilles tendons in a new experimental mouse model. In 114 Balb-C-mice the left Achilles tendon was transected and sutured by the Kirchmayr-Kessler technique. The tendons healed either under(More)
Hepatic ischemia/reperfusion injury has so far been investigated in various experimental models. A clinical transfer of experimental results is, however, problematic because of anatomical and physiological differences and also the inevitable simplification of experimental work. The choice of model must therefore be adapted to the clinical question to be(More)
In vivo microscopy is an excellent technique for investigating the microcirculation and until recently the only one that allowed direct visualization. Rat liver has been widely studied, because microcirculatory disorders play a pivotal role in the pathogenesis of organ failure during hepatic ischemia, transplantation, hemorrhagic shock, endotoxemia, and(More)
Liver transplantation in rats is frequently used as a transplantation model. Although liver transplantation in larger laboratory animals such as dogs and pigs is technically easier, the rat has become the most important subject for experimental liver transplantation because of the availability of genetically defined animals. Numerous surgical techniques(More)
The implantation of antibiotic-containing cement beads became standard adjuvant local antibiotic therapy of chronic osteomyelitis. The new developed bioabsorbable drug carrier system of polyglycolic acid with the antibiotic Ciprofloxacin was tested in vitro and in vivo. The goal of this study was to determinate the penetration depth of Ciprofloxacin into(More)
