Total hepatic ischemia and reperfusion after state controlled hemorrhagic shock, with used of different solutions: effects of neutrophils sequestration in kidney of rats.

Purpose: To evaluate and compare neutrophils sequestration in the renal cortex of rats, result of total hepatic ischemia and reperfusion after controlled hemorrhagic shock, with use of different electrolytic solutions.

Methods: Used 18 rats Wistar, males, adult, divided into three groups as the solution used to reanimation: Group PSS: physiologic saline solution; Group HSS: hypertonic saline hypertonic (7.5%) followed by lactated ringer's solution; Group LRS: lactated ringer's solution.

Hemodynamic parameters and neurogenic pulmonary edema following spinal cord injury: an experimental model.

Neurogenic pulmonary edema is a serious and always life-threatening complication following several lesions of the central nervous system. We report an experiment with 58 Wistar-Hanover adult male rats. Two groups were formed: control (n=4) and experimental (n=54).

[Total hepatic ischemia and reperfusion under normal conditions and submitted to controlled hemorrhagic shock state: effects of neutrophil sequestration in kidney of rats].

Purpose: The evaluate the effects of total hepatic ischemia and reperfusion under normal conditions and submitted to controlled hemorrhagic shock state on the accumulation of neutrophils in the cortex renal of rats.

Methods: In this experiment 32 male adult Wistar mice, were divided into four groups: Control Group (CG), submitted to the catheterizations and laparotomy, followed by a period 60 minutes of observation; Shock Group (SG): controlled of hemorrhagic shock (CHS) for 20 minutes (20'), mean arterial pressure (MAP) 40 mmHg, followed by reanimation and reperfusion for 60 minutes (RP60); Pringle Group (PG): Pringle's Maneuver (PM) for 15 minutes (15'), followed for RP60'; Shock-Pringle Group (SPG): CHS (MAP = 40 mmHg) for 20' followed by laparotomy and PM for 15', followed for RP60'. To characterize the poor tissular perfusion blood lactate and the base reserve were measured.

[Treatment of complex duodenal lesions: comparison between simple suture and suture with pyloric exclusion and gastrojejunostomy in dogs].

Purpose: The goal of this study is to compare the results of two different procedures to complex duodenal lesion (grade III), in an animal model.

Methods: Twenty-four mongrel dogs, weighting 10 to 15 kg, were distributed in 4 groups of 6 animals each. All animals were submitted to a complex duodenal lesion (grade III), with a 50% loss of its circumference.

Investigating the relationship between hemodynamic and metabolic parameters in portal triade occlusion following hemorrhagic shock.

Purpose: To determine whether metabolic and hemodynamic parameters are "mathematically" coupled in rats submitted to portal triad occlusion following controlled hemorrhagic shock state.

Methods: Pearson's coefficient (r-value) analysis was performed. Differences considered significant at p < 0.

Importance of anesthesia for the genesis of neurogenic pulmonary edema in spinal cord injury.

There are reports describing both provocation and inhibition of neurogenic pulmonary edema by anesthetic drugs. Therefore, we compared the effect of two types of anesthesia on the formation of neurogenic pulmonary edema in rats with balloon-induced acute spinal cord injury. Animals with sham procedure (group 1) were anesthesized by intraperitoneal sodium pentobarbital.
