Hypertonic sodium pyruvate (HSP), as well as ethyl pyruvate solutions, has been proposed as resuscitative fluids in the treatment of hemorrhagic shock (HS) because of their anti-inflammatory and antioxidant properties. The effectiveness of one pyruvate preparation over the other in the treatment of
Classical experimental models of hemorrhage are characterized by the use of anesthetics that may interfere with the typical immune responses and pathology of hemorrhage/resuscitation. Thus, therapeutic strategies successful in anesthetized animals might not be beneficial in clinical trials. In this
Reactive species of oxygen have been implicated as being important mediators in a variety of pathologic conditions, including burns, various forms of ischemia/reperfusion injury, and hemorrhagic shock. Pyruvate, an intermediate in the metabolism of glucose, is a potent reactive species of oxygen
Previous studies have demonstrated the neuroprotective effects of ethyl pyruvate in central nervous system (CNS) diseases. However, whether ethyl pyruvate attenuates early brain injury after subarachnoid hemorrhage (SAH) remains unknown. This study was conducted to investigate the potential effects
Administration of pyruvate, an effective scavenger of reactive oxygen species, has been shown to be salutary in numerous models of redox-mediated tissue or organ injury. Pyruvate, however, is unstable in solution and, hence, is not attractive for development as a therapeutic agent. Herein, ethyl
After blunt thoracic trauma (TxT) and hemorrhagic shock with resuscitation (H/R) intense local inflammatory response and cell loss frequently impair the pulmonary function. Ethyl pyruvate (EP) has been reported to improve the pathophysiologic derangements in models of acute inflammation. Here, we
Hemorrhage remains a common cause of death despite the recent advances in critical care, in part because conventional resuscitation fluids fail to prevent lethal inflammatory responses. Here, we analyzed whether ethyl pyruvate can provide a therapeutic anti-inflammatory potential to resuscitation
Reactive oxygen species (ROS) have been implicated in the pathogenesis of hemorrhagic shock. Ethyl pyruvate, a derivative of pyruvate and a proposed oxygen radical scavenger, is attractive as a possible resuscitation fluid. We investigated whether resuscitation with lactated Ringer's (LR) containing
We previously showed that pretreatment with a solution of ethyl pyruvate in a calcium-containing balanced salt solution, Ringer's ethyl pyruvate solution (REPS), ameliorates gut mucosal damage in rats subjected to mesenteric ischemia/reperfusion. Herein, we sought to test the hypothesis that REPS
Early brain injury (EBI) following subarachnoid hemorrhage (SAH) is the main cause to poor outcomes of SAH patients, and early inflammation plays an important role in the acute pathophysiological events. It has been demonstrated that ethyl pyruvate (EP) has anti-inflammatory and neuroprotective
The treatment of patients with multiple trauma including blunt chest/thoracic trauma (TxT) and hemorrhagic shock (H) is still challenging. Numerous studies show detrimental consequences of TxT and HS resulting in strong inflammatory changes, organ injury and mortality. Additionally, the reperfusion
Ethyl pyruvate (EP) is a pyruvate derivative and known to be cytoprotective in various pathological conditions through anti-cell death and anti-inflammatory mechanisms. The present study investigated the neuroprotective effect of ethyl pyruvate using a mouse model of collagenase-induced
Reactive oxygen species are reactive, partly reduced derivatives of molecular oxygen. Important reactive oxygen species in biological systems include superoxide radical anion, hydrogen peroxide, and hydroxyl radical. Peroxynitrite, is another important species in biological systems. A variety of
OBJECTIVE
Severe hemorrhage is a common cause of death despite the recent advances in critical care. Conventional resuscitation fluids are designed to reestablish tissue perfusion, but they fail to prevent lethal inflammatory responses. Our previous studies indicate that ethyl pyruvate (EP) inhibits
Pyruvate plays a central role in intermediary metabolism. Pyruvate, however, is also a potent antioxidant and free radical scavenger, and numerous studies have shown that treatment with this compound can be salutary in numerous pathologic conditions that are thought to be mediated, at least in part,
