Ischemia-reperfusion-caused hemorheological alterations have been widely studied but the effect of testicular ischemia-reperfusion has not so far. In this study 14 Sprague-Dawley rats were involved. In the ischemia-reperfusion group under general anaesthesia the left testis was explored by opening the scrotum then the deferent duct and vasculature were(More)
Investigation of regional hemorheological properties are important in ischemia-reperfusion experimental surgical and microsurgical research models, however, the physiological arterio-venous as well as porto-caval differences in erythrocyte deformability and aggregation are still controversial. In this study, besides measuring blood pH, blood gases, lactate(More)
PURPOSE To investigate the intraoperative microcirculatory changes of the affected organs (small bowel, liver and kidney) during the making of a modified selective portacaval (PC) shunt. METHODS On ten anaesthetized Sprague-Dawley rats the selective end-to-side mesocaval anastomosis was performed, where only the rostral mesenteric vein is utilized and the(More)
PURPOSE The failure of small-caliber vascular grafts still means a serious problem. Concerning the early postoperative complications we aimed to investigate the hemostaseological and hemorheological aspects of this issue in a canine model. METHODS In the Control group only anesthesia was induced. In the Grafted group under general anesthesia a 3.5-cm(More)
Testicular torsion may lead to serious ischemia, and the viability depends on the duration of torsion and the effect of ischemia-reperfusion. Testicular decompression and tunica vaginalis flap application technique were introduced in 2008 by Kutikov et al. We aimed to examine the impact of this method on the testicular microcirculation and hemorheological(More)
It is known that red blood cell deformability may show colorful inter-species differences, influenced by inner viscosity, cell membrane viscosity, morphology and surface-volume ratio of the erythrocytes. It is also well-known that the cell volume is changing depending on the micro-environmental osmolarity. These changes can be well observable using osmotic(More)
PURPOSE To examine how the ischemia-reperfusion injury of latissimus dorsi-cutaneous maximus (LDCM) musculocutaneous flap affects the microcirculatory (flap's skin surface) and hemorheological parameters, and whether an intraoperative deterioration would predictively suggest flap failure in the postoperative period. METHODS Ten healthy male rats were(More)
Previously we have investigated the cerulein-induced acute pancreatitis and provided data on its micro-rheological impact in the rat. We hypothesized that non-steroid anti-inflammatory agent flunixin, the xanthine-derivate pentoxifylline and the low molecular weight heparin enoxaparin may have various beneficial effects improving microcirculatory and(More)
We aimed to investigate hemodynamic, microcirculatory and hemorheological consequence of infrarenal or suprarenal aortic cross-clamping (IRAXC, SRAXC) in the rat. We hypothesized that the magnitude of the changes are different. Twenty-one male rats were randomized into Control, IRAXC or SRAXC groups. Under anesthesia the right carotid artery was cannulated(More)
