Abstract

Hemorrhagic shock is a life threatening condition characterized by diminishing organ function. The aim of this study was to determine whether an effective pyrrolidine dithiocarbamate (PDTC) treatment protocol could be established to decrease organ dysfunction and mortality in a lethal hemorrhagic shock-resuscitation (HSR) model. Sprague-Dawley rats were randomized into three experimental groups; HSR alone (HSR), PDTC (100 mg/kg) administered 12 h pre-HSR (PDTC-12), and PDTC administered 1 h post-shock prior to resuscitation (PDTC+1). Hemorrhage was induced by arterial blood withdrawal to a mean arterial pressure (MAP) of 25 ± 5 mmHg for 1 h. Resuscitation was performed until pre-HSR MAP was attained. Blood was collected immediately prior to HSR, 1 h post-shock, and at protocol end. Measurements of base excess, lactate, arterial partial pressure of carbon dioxide (PaCO(2)) and oxygen (PaO(2)), alanine aminotransferase (ALT), aspartate aminotransferase (AST), creatinine, blood urea nitrogen (BUN), and lipase were performed. In PDTC+1 animals, PDTC was ineffective in improving survival. In contrast, survival was significantly increased in the PDTC-12 animals versus PDTC+1 and HSR groups. Analysis of physiologic parameters demonstr...Continue Reading

Apoptosis

Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis
