Abstract
Ischemia-reperfusion injury (IRI) is a process in which damage is induced in hypoxic tissue when oxygen supply is resumed after ischemia. During IRI, restoration of reduced nitric oxide (NO) levels may alleviate reperfusion injury in ischemic organs. The protective mechanism of NO is due to anti-inflammatory effects, antioxidant effects, and the regulation of cell signaling pathways. On the other hand, it is generally known that S-nitrosylation (SNO) mediates the detrimental or protective effect of NO depending on the action of the nitrosylated target protein, and this is also applied in the IRI process. In this review, the effect of each change of NO and SNO during the IRI process was investigated.

Resuscitation after hemorrhagic shock: the effect on the liver--a review of experimental data. J Anesth 2012; 27:447-60.

Abstract
The liver is currently considered to be one of the first organs to be subjected to the hypoxic insult inflicted by hemorrhagic shock. The oxidative injury caused by resuscitation also targets the liver and can lead to malfunction and the eventual failure of this organ. Each of the various fluids, vasoactive drugs, and pharmacologic substances used for resuscitation has its own distinct effect(s) on the liver, and the anesthetic agents used during surgical resuscitation also have an impact on hepatocytes. The aim of our study was to identify the specific effect of these substances on the liver. To this end, we conducted a literature search of MEDLINE for all types of articles published in English, with a focus on articles published in the last 12 years. Our search terms were "hemorrhagic shock," "liver," "resuscitation," "vasopressors," and "anesthesia." Experimental studies form the majority of articles found in bibliographic databases. The effect of a specific resuscitation agent on the liver is assessed mainly by measuring apoptotic pathway regulators and inflammation-induced indicators. Apart from a wide range of pharmacological substances, modifications of Ringer's Lactate, colloids, and pyruvate provide protection to the liver after hemorrhage and resuscitation. In this setting, it is of paramount importance that the treating physician recognize those agents that may attenuate liver injury and avoid using those which inflict additional damage.

Role of exogenous nitric oxide donor in treatment of decompensated hemorrhagic shock in normotensive and hypertensive rats. J Biomed Biotechnol 2012; 2012:365195. [PMID: 22778548 PMCID: PMC3385006 DOI: 10.1155/2012/365195] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2012] [Revised: 04/07/2012] [Accepted: 04/21/2012] [Indexed: 02/04/2023] Open
Abstract
INTRODUCTION In this study, we investigated the role of exogenous NO donor, sodium nitroprusside (SNP), on hemodynamic responses and survival rate during decompensated hemorrhagic shock in normotensive and hypertensive rat. METHODS Male wistar rats were divided into normotensive and hypertensive groups (n = 12 each). Then, the animals were subjected to decompensated hemorrhagic shock by withdrawing blood until the mean arterial pressure (MAP) reached to 40 mmHg. After the shock period, the animals were randomly assigned to SNP-treated (0.5 mg/kg) and control groups (n = 6 each). MAP and heart rate (HR) were monitored throughout the experiment and 60 min after the administration of drug. Serum NO concentrations were measured. The survival rate was counted during next 72 h. RESULTS Infusion of SNP caused no significant changes in MAP and HR in normotensive and hypertensive animals. Hemorrhagic shock increased serum NO concentration and SNP administration reduced serum NO concentration in either normotensive or hypertensive groups. Survival counts during 72 h after experiment did not improve by SNP administration, and there were no significant differences between normotensive and hypertensive groups. CONCLUSION SNP administration cannot improve hemodynamic responses and survival count during decompensated hemorrhagic shock in normotensive and hypertensive animals.

Abstract
BACKGROUND We evaluated the effect of hypertension on hemodynamic responses and serum nitrite concentrations in normotensive (NT) and deoxycorticosteron acetate (DOCA)-Salt hypertensive (HT) rats. METHODS Uncontrolled hemorrhagic shock was induced in NT and HT rats (n=7 each) by preliminary bleed of 25 ml/kg followed by a 75% tail amputation. The mean arterial pressure (MAP), heart rate and serum nitrite were measured pre-hemorrhage and during hemorrhage. RESULTS Changes in time-averaged MAP after hemorrhage were significantly greater in HT group than NT. After resuscitation, the HT rats failed to restore MAP to baseline level. Serum nitrite level in both groups was significantly increased during shock period. Survival rate of HT animals was lower than NT group, although it was not statistically significant. CONCLUSIONS Marked reduction of MAP and less improvement after resuscitation suggested the less adaptation of cardiovascular system in HT animals which may interfere with management of these subjects during uncontrolled hemorrhagic shock.

Abstract
The selective regulation of total peripheral circulation in hypovolemic crisis offers a unique approach for treating and preventing hemorrhagic shock. Ideally, such a therapeutic intervention would require targeting of the striated muscle vascular beds without altering the vascular resistance in vital organ vascular beds. We discovered that a combination of cannabinoid receptor agonist, THC (Δ-tetrahydrocannabinol), and cyclooxygenase 2 inhibitor, NS-398, caused selective microvascular constriction in the mouse cremaster muscle manifested by a pronounced and significant 27.4% ± 7.9% decrease in vessel diameter relative to control (P < 0.01). This observation, and the reported lack of microvascular response in the mesentery and brain, led us to hypothesize that the drug combination could favorably redistribute blood volume in hypovolemia and prolong survival. To test the hypothesis, male Sprague-Dawley rats were subjected to a pressure-controlled hemorrhage (mean arterial pressure reduced to 30 ± 13.73 mmHg) then randomly assigned to one of six treatment groups (n = 6 per group). The untreated, NS-398-treated, and THC-treated groups manifested an insignificant difference in survival between groups after shock. The group treated with a combination of THC and NS-398 manifested a significant increase in mean survival from 53 ± 12 to 227 ± 23 min after shock (P < 0.001). The drug combination significantly reduced IL-1α, IL-1β, IFN-γ, and IL-10 production compared with the group resuscitated with normal saline. In addition, histological evaluation indicated that the therapy protects the lungs and liver against hemorrhagic shock-induced damage. The combination of cannabinoid receptor agonist and cyclooxygenase 2 inhibitor represents a potentially new approach to low-volume therapeutic intervention for hypovolemia.

Abstract
Recent studies have shown that erythropoietin, critical for the differentiation and survival of erythrocytes, has cytoprotective effects in a wide variety of tissues, including the kidney and lung. However, erythropoietin has been shown to have a serious side effect-an increase in thrombovascular effects. We investigated whether pyroglutamate helix B-surface peptide (pHBSP), a nonerythropoietic tissue-protective peptide mimicking the 3D structure of erythropoietin, protects against the organ injury/ dysfunction and inflammation in rats subjected to severe hemorrhagic shock (HS). Mean arterial blood pressure was reduced to 35 ± 5 mmHg for 90 min followed by resuscitation with 20 mL/kg Ringer Lactate for 10 min and 50% of the shed blood for 50 min. Rats were euthanized 4 h after the onset of resuscitation. pHBSP was administered 30 min or 60 min into resuscitation. HS resulted in significant organ injury/dysfunction (renal, hepatic, pancreas, neuromuscular, lung) and inflammation (lung). In rats subjected to HS, pHBSP significantly attenuated (i) organ injury/dysfunction (renal, hepatic, pancreas, neuromuscular, lung) and inflammation (lung), (ii) increased the phosphorylation of Akt, glycogen synthase kinase-3β and endothelial nitric oxide synthase, (iii) attenuated the activation of nuclear factor (NF)-κB and (iv) attenuated the increase in p38 and extracellular signal-regulated kinase (ERK)1/2 phosphorylation. pHBSP protects against multiple organ injury/dysfunction and inflammation caused by severe hemorrhagic shock by a mechanism that may involve activation of Akt and endothelial nitric oxide synthase, and inhibition of glycogen synthase kinase-3β and NF-κB.

Abstract
Statins are established in the prevention and therapy of chronic cardiovascular diseases because of inhibition of HMG-CoA (3-hydroxy-3-methylglutaryl-coenzyme A), thus lowering blood cholesterol levels. However, their cholesterol-independent effects include regulation of Rho/Rho-kinases (ROCK) and eNOS, proteins centrally involved in various models of acute inflammation. Therefore, we tested the hypothesis that simvastatin confers protection after rat hemorrhage/resuscitation (H/R) and wanted to elucidate the mechanisms involved. Fifty-two female Lewis rats (180-250 g) were pretreated with simvastatin 5 mg/kg per day or vehicle for 6 days (i.p.). Then, rats were hemorrhaged to a mean arterial pressure of 30 +/- 2 mmHg for 60 min and resuscitated. Control group underwent surgical procedures without H/R. Two hours after resuscitation, tissues were harvested. Mortality was assessed 72 h after H/R. Simvastatin pretreatment increased survival after H/R from 20% to 80%. Serum alanine aminotransferase after H/R increased 2.2-fold in vehicle as compared with simvastatin-treated rats. Histopathological analysis revealed decreased hepatic necrosis in simvastatin-treated rats after H/R. Hepatic oxidative (4-hydroxynonenal) and nitrosative (3-nitrotyrosine) stress, inflammatory markers (serum IL-6 and hepatic infiltration with polymorphonuclear leukocytes), and actin cytoskeleton rearrangements were decreased after simvastatin pretreatment compared with vehicle-treated rats after H/R. Simvastatin increased eNOS and heme oxygenase 1 expression and eNOS activation. Expression of Rho/Rho-kinase and myosin phosphatase targeting subunit, Thr-MYPT1, a marker for Rho-kinase activity, decreased after simvastatin treatment compared with vehicle-treated rats after H/R. Simvastatin pretreatment exerts beneficial effects in this model of acute inflammation by supporting protective mechanisms that are important for hepatic microcirculation after H/R.

Abstract
In 1992 nitric oxide (NO) was declared molecule of the year by Science magazine, and ever since research on this molecule continues to increase. Following this award, NO was shown to be a mediator/protector of ischemia and reperfusion injury in many organs, such as the heart, liver, lungs, and kidneys. Controversy has existed concerning the actual protective effects of NO. However, literature from the past 15 years seems to reinforce the consensus that NO is indeed protective. Some of the protective actions of NO in ischemia and reperfusion are due to its potential as an antioxidant and anti-inflammatory agent, along with its beneficial effects on cell signaling and inhibition of nuclear proteins, such as NF-kappa B and AP-1. New therapeutic potentials for this drug are also continuously emerging. Exogenous NO and endogenous NO may both play protective roles during ischemia and reperfusion injury. Sodium nitroprusside and nitroglycerin have been used clinically with much success; though only recently have they been tested and proven effective in attenuating some of the injuries associated with ischemia and reperfusion. NO inhalation has, in the past, mostly been used for its pulmonary effects, but has also recently been shown to be protective in other organs. The potential of NO in the treatment of ischemic disease is only just being realized. Elucidation of the mechanism by which NO exerts its protective effects needs further investigation. Therefore, this paper will focus on the mechanistic actions of NO in ischemia and reperfusion injury, along with the compound's potential therapeutic benefits.

Abstract
In hemorrhagic shock (HS) an increased thymic apoptosis (TA) was described. The aim of this study was to evaluate the effect of administration of the caspase inhibitor N-benzyloxy-carbonil-Val-Ala-Asp-fluoromethylketone (Z-VAD-FMK) during the resuscitation phase on TA, organ dysfunctions, and tumor necrosis factor (TNF)-alpha release in HS. Forty rats were randomly assigned to four groups: no HS/resuscitation (sham); HS/resuscitation with shed blood and normal saline (control); HS/resuscitation with shed blood and phosphate-buffered solution (PBS) (vehicle); and HS/resuscitation with shed blood and Z-VAD-FMK (inhibitor). Rats were subjected to HS by blood removal to a MAP of 35-40 mmHg. After a 1-h shock period, the animals were resuscitated according to the protocol. At 1 and 3 h after resuscitation, transaminases, creatinine, urea, lipase, TNF-alpha, and TA were evaluated. Our study showed that a nonlethal HS is early able to induce organ dysfunctions and increased TA. Administration of Z-VAD-FMK did not significantly decrease organ dysfunctions, while it induced a significant TNF-alpha release. TA was significantly reduced by Z-VAD-FMK after 1 h, but not after 3 h. Our results suggest that postinjury caspase inhibition does not attenuate organ dysfunctions, and also does not permanently reduce TA induced by HS and resuscitation in rats.

Abstract
BACKGROUND The up-regulation of nitric oxide (NO) and cyclooxgenase-2 (COX-2) has been implicated in the pathophysiology of hemorrhagic shock. We examined the effects of aminoguanidine (AG), which is a known inducible nitric oxide synthase (iNOS) inhibitor, and NS-398, a known COX-2 inhibitor, in our rat model of refractory hemorrhagic shock (RHS). MATERIAL AND METHODS We measured tissue iNOS and COX-2 protein expression, brain and plasma nitrate/nitrite and prostaglandin E2 (PGE2) levels, plasma creatinine and glutamic oxalacetic transaminase (GOT) levels, quantified the histological damages in kidney, liver, lung, and brain, survival rate, and mean arterial blood pressure (MABP) in RHS rats. RESULTS Semiquantitative analysis of tissues showed iNOS protein was not detected in AG + RHS rats but was detected in normal saline and NS-398 RHS rats. Tissue COX-2 protein was not detected in AG and NS-398 RHS rats but was detected in normal saline + RHS rats. The levels of brain and plasma nitrate/nitrite and PGE2 and plasma creatinine and GOT were significantly lower in the AG + RHS rat group when compared with the normal saline RHS rat group. Histological examinations also showed a reduction in organ damage for AG + RHS rats when compared with treated RHS rats. AG + RHS rats showed significantly increased survival and MABP level when compared with treated RHS rats. CONCLUSION Our present findings suggest that NO produced by iNOS might result in organ damages. This in turn might lead to COX-2 up-regulation, and it increases the production of reactive oxygen species and toxic prostanoids. NO-mediated organ damage might be one way in which toxic products of COX-2 might further contribute to NO's deleterious effect in the later stages of RHS. It is therefore suggested that treatment of AG via inhibition of NO might contribute to improved physiological parameters and survival rates following RHS.
