[Effects of phosphatidylcholine therapy after hindlimb ischemia and reperfusion].

Background: Microcirculatory dysfunctions and mast cell reactions play important roles in hypoxic tissue injuries. The aims of this study were to characterize the effects of hindlimb ischemia-reperfusion on the periosteal microcirculation and to define the consequences of systemic phosphatidylcholine therapy during this condition.

Materials And Methods: Microcirculatory changes were visualized by means of fluorescence intravital videomicroscopy in anesthetized Wistar rats.

Beneficial effects of phosphatidylcholine during hindlimb reperfusion.

Background: Microcirculatory dysfunctions and mast cell (MC) reactions play important roles in hypoxic tissue injuries. The aims of this study were to characterize the effects of hindlimb ischemia-reperfusion (I-R) on the periosteal microcirculation and to define the consequences of systemic phosphatidylcholine (PC) therapy during this condition.

Materials And Methods: Microcirculatory changes were visualized by means of fluorescence intravital videomicroscopy in anesthetized Wistar rats.

[Early clinical experience with postoperative monitoring of a patient after laparoscopic splenectomy combined with spleen autotransplantation. A case report].

We performed splenectomy combined with spleen autotransplantation after blunt abdominal trauma by minimally invasive technique at the County Teaching Hospital in Kecskemét. In case of advanced post traumatic spleen injury, spleen autotransplantation (Furka's spleen chips) is a well-known method to try to avoid postsplenectomy syndrome. During the operation, when in situ preservation of the spleen is not possible, chips of spleen tissue are transplanted into the omentum.

Endothelin-a receptor antagonist treatment improves the periosteal microcirculation after hindlimb ischemia and reperfusion in the rat.

Objectives: To examine the microcirculatory changes in the rat tibial periosteum after hindlimb ischemia and reperfusion and to evaluate the effects of endothelin-A (ET-A) receptor antagonist therapy in this condition. The healing and functioning of vascularized bone autografts depend mainly on the patency of the microcirculation, and the activation of ET-A receptors may be an important component of the tissue response that occurs during ischemia-reoxygenation injuries.

Methods: Wistar rats were subjected to 1 hour of hindlimb ischemia and 3 hours of reperfusion.
