Presents article is deal with optimization of the fixture for end milling process, the most important objective being the minimization of work piece deformation by changing the layout of fixture elements and the clamping forces. The main objective of this work has been the optimization of the fixtures Work piece deformation subjected to clamping forces for End milling operation. The present ana...

conclusions continuous portal triade clamping (the pringle maneuver) during liver ischemia (30 and 45 minutes) in rabbits resulted in no ischemic change. increasing time of clamping to 30 minutes was safe in intermittent pringle maneuver. materials and methods in an experimental study, 20 new-zealand white rabbits were selected. in laparotomy, a blunt dissector was passed through the foramen of...

BACKGROUND The aim of this study was to collect important data on the time of oxygen saturation change in relation to skin flap color alteration using non-invasive pulse oximetry to evaluate its ability to provide continuous monitoring of skin flap perfusion. METHODS An experimental study on the monitoring of blood perfusion of 20 tube-island groin flaps of 10 male New Zealand rabbits was per...

Cyclosporin A pharmacokinetics were studied after oral (4-14 mg/kg body weight) and intravenous dosing (1.5-3.5 mg/kg) in 13 orthotopic liver transplant recipients before and after permanent clamping of the biliary T-tube. After T-tube clamping, cyclosporin A absorption was faster and more complete with the mean time of peak concentration, tmax, reduced to around three hours from around six hou...

Objective- This study investigated the effect of amlodipine on intestinal ischemia-reperfusion injury in ratsDesign-Experimental studyAnimals-Fifteen male Sprague-Dawly rats weighing 200-220gProcedure- Rats were randomly divided into 3 groups: IR group (operation with clamping), sham group (operation without clamping), and IRA group (operation with clamping and 5mg/kg amlodipi...

In order to find the ideal distal circulatory support during cross-clamping of the descending thoracic aorta, the author compared the effects of simple shunting (SS) and centrifugal pump (CP) on hemodynamics and metabolisms in mongrel dogs. In group I (control), the aorta was cross-clamped for two hours without SS or CP; in group II (SS), a temporary shunt was placed between the left common car...

BACKGROUND AND OBJECTIVES Infra-renal aortic cross-clamping is associated to renal effects. This study aimed at analyzing halothane, isoflurane and sevoflurane effects on renal function of dogs submitted to infra-renal aortic cross-clamping. METHODS This study involved 30 mixed-breed dogs randomly distributed in three groups, according to equipotent anesthetic doses (0.75 MAC) of inhaled anes...
