The impact of 3 different reperfusion sequences following orthotopic liver transplantation (OLT) in pigs were evaluated. The reperfusion technique commonly performed is primary portal in order to shorten warm ischemic times (WITs). Experimental and clinical data, usually comparing 2 out of 3 possible reperfusion sequences, provide controversial results. OLT was performed in 24 pigs randomized into 3 groups: primary arterial (A), simultaneous (SIM), and primary portal (P) reperfusion. Hemodynamics were continuously monitored and reperfusion injury and primary graft function were assessed by standard serum parameters, histopathological findings, immunohistochemistry for heme oxygenase 1 (HO-1), and heat shock protein 70 (HSP 70). Aspartate aminotransferase (AST), alanine aminotransferase (ALT), lactate dehydrogenase (LDH), and gamma-glutamyl transpeptidase (gammaGT) following reperfusion were significantly increased for group A when compared to groups SIM and P. Hemodynamics showed significant differences after reperfusion compared to physiological data; differences in group comparisons were not significant. The bile production/100 g liver/hr was significantly higher for group SIM (1.15 mL) compared to group P (0.66 mL) and group A (0.62 mL). Histology and immunohistochemistry significantly correlated with functional results and outcome. Histological score was best for group SIM and worst for group A. HSP 70, being visualized mainly in the hepatocytes, showed higher expression for groups SIM and P. Inversely, HO-1, found in perisinusoidal cells, showed highest expression after primary arterial reperfusion. In conclusion, although associated with a 10-minute longer warm ischemic time, simultaneous reperfusion causes the least reperfusion injury with superior primary transplant function. Primary arterial reperfusion showed the worst overall outcome and highest degree of HO-1 expression. 相似文献

Ischemic preconditioning improves rat kidney graft function after severe ischemia/reperfusion injury 总被引:10,自引:0,他引:10
Ischemic preconditioning (IP) has been shown to ameliorate renal ischemia reperfusion injury. Using a rat kidney transplantation model we determined if IP improves graft function after prolonged cold storage. MATERIALS AND METHODS: Syngeneic rat kidneys were divided into two groups. Prior to 42 hours of cold storage in UW and transplantation, one group (n = 10) received IP (15 minutes of warm ischemia/10 minutes of reperfusion), whereas another group (n = 10) received no treatment. Early graft function and 1-week recipient survival were assessed. RESULTS: Recipient survival was not significantly different between groups [70% (IP) vs 40% (non-IP); P = .28]. IP treatment led to a quicker recovery of renal function. On PODs 3 and 6, serum creatinine levels in the IP group were significantly lower compared with the untreated group. In conclusion, one cycle of IP (15/10) accelerates recovery of renal graft function after severe ischemia reperfusion injury. This simple treatment modality may improve outcomes of renal transplants with prolonged cold storage. 相似文献

海马CA1区对脑缺血最为敏感,即使短暂的脑缺血也可造成锥体细胞凋亡。我们的前期研究发现,多巴胺D:受体激动剂培高利特(pergolide)可显著减轻沙土鼠脑缺血/再灌注损伤后行为学异常,减少海马CA1区锥体细胞凋亡,其脑保护作用与诱导bcl-2并抑制bax基因的表达有关。既往研究表明,脑缺血后c-jun表达的增高与细胞凋亡密切相关。本实验应用HE染色法、DNA原位末端标记(TUNEL)法及免疫组织化学染色方法,观察对沙土鼠前脑缺血再灌注后海马CA1区神经元凋亡和c-jun表达的影响,探讨培高利特发挥脑保护作用的基因调控机制。 相似文献

Endothelin is a potent hepatic vasoconstrictor. We evaluated the role of an endothelin antagonist in hepatic ischemia/reperfusion
injury. Bosentan, a novel endothelin receptor antagonist, was infused directly into the portal vein prior to cold ischemia
and immediately on reperfusion, in five porcine livers. Five other pigs underwent routine liver harvest and reperfusion without
bosentan treatment. Hepatic vascular resistance and liver tissue blood flow, as measured by thermistor flow probes, were determined
following reperfusion. Hepatocellular damage was assessed through hepatic venous levels of sorbitol dehydrogenase and lactate
dehydrogenase. Endothelial cell damage was determined in sections immunostained for factor VIII. Graft function was determined
through oxygen consumption, bile production, and response to bile acid challenge. Organs treated with bosentan demonstrated
lower vascular resistance and enhanced tissue blood flow (P <0.05) as compared to untreated organs. Portal vein inflow to hepatic tissue was significantly enhanced (4.4-fold) in the
bosentan-treated organs (P <0.05). No difference was observed in hepatocellular damage. Pathology scores for factor VIII immunohistochemical staining
were 2.3-fold higher in the bosentan-treated livers as compared to untreated livers (P <0.05). The bosentantreated livers also demonstrated enhanced oxygen consumption, increased bile production, and augmented
biliary response to a bile acid challenge (P <0.05). These results indicate that administration of bosentan before and after ischemia/reperfusion reduces hepatic circulatory
disturbances, diminishes endothelial cell damage, and augments hepatic graft function.

Renal ischemia/reperfusion injury could arise as a consequence of clinical conditions such as renal transplantation, shock, cardiac arrest, hemorrhage and renal artery surgery. In this experimental study, we aimed to determine the preventive effects of amrinone on bilateral renal ischemia/reperfusion injury in rats. A total of 60 Wistar-albino rats were divided into six groups ( n=10). Midline laparotomies were made under ketamine anesthesia. In the sham, amrinone1 and amrinone2 without ischemia (AWI1 and AWI2) groups saline, 5 and 10 mg/kg of amrinone was infused, respectively. In the ischemia, ischemia plus amrinone1 (IPA1) and ischemia plus amrinone2 (IPA2) groups, saline and 5 and 10 mg/kg of amrinone was infused, respectively, at the beginning of reperfusion, subsequent to 45 min of bilateral renal artery occlusion. Following 6 h of reperfusion, blood was drawn to study serum BUN and creatinine and a bilateral nephrectomy was done to determine tissue malonyldialdehyde ( MDA) and myeloperoxidase (MPO) levels. The results were analysed by Mann-Whitney U-test. The parameters studied were statistically higher in the ischemia group compared with the other groups ( P<0.05 for each comparison), indicating renal I/R injury. These parameters were lower in the amrinone without ischemia groups (AWI1 and AWI2) than in the sham group, however there were no significant differences between the groups ( P>0.05, for each comparison). The treatment groups IPA1 and IPA2 had statistically similar results compared with the sham group, showing the preventive effect of amrinone on renal I/R injury at the given doses. We conclude that amrinone prevented experimental renal ischemia/reperfusion injury in rats, independently of the administered doses. This preventive effect of the agent could depend on its effect of regulating the microcirculation, in decreasing intracellular calcium and in preventing neutrophil activation. We propose that this preventive effect of amrinone - which has gained clinical application especially in cases of cardiac insufficiency - could also be exploited in clinical conditions related with renal ischemia/reperfusion. 相似文献

Ischemia and reperfusion contribute to substantial organ damage in transplantation. Clinically feasible measures for the prevention thereof are scarce. We tested whether rinsing rodent hearts with the antioxidant bilirubin ameliorates ischemia reperfusion injury (IRI). Left ventricular end‐diastolic pressure (LVEDP), left ventricular developed pressure (LVDevP), rate per pressure product (RPP), coronary flow, maximum (+dP/dt) and minimum (?dP/dt) rate of contraction were analyzed in Lewis rat hearts rinsed with bilirubin prior to reperfusion on a Langendorff apparatus after 12 h of cold ischemia. In vivo, isogenic C57Bl/6 mouse hearts rinsed with bilirubin were transplanted after 12 h of cold ischemia. Cardiac function and apoptosis were assessed 24 h after reperfusion. Heart lysates recovered 15 min after reperfusion were probed for the total and the phosphorylated forms of extracellular signal‐related protein kinases (ERK), JNK, p38‐MAPK, and Akt. In isolated perfused hearts, bilirubin rinse resulted in significantly lower LVEDP and improved LVDevP, RPP, coronary flow, +dP/dt and ?dP/dt. In vivo, after reperfusion, all mitogen‐activated protein kinases (MAPKs) were suppressed significantly by bilirubin pretreatment. Bilirubin rinse improved cardiac scores (3.4 ± 0.5 vs. 2.0 ± 1.0 in controls, P < 0.05) and significantly suppressed apoptosis. Ex vivo administration of bilirubin to heart grafts prior reperfusion ameliorates IRI and provides a simple and effective tool to ameliorate outcome in heart transplantation. 相似文献

Mesenteric ischemia occurs in a number of clinically relevant pathophysiologic processes, including sepsis, hemorrhage, intestinal transplantation, severe burns, and mesenteric thrombosis. The readmission of molecular oxygen into an ischemic tissue promotes the oxidation of resuscitated tissue with certain pathophysiologic mechanisms. Depending on the duration and the intensity of ischemia, reoxygenation of the intestine that has been reperfused may further induce tissue injury. Intestinal ischemia and reperfusion injury can accelerate complex processes between the endothelium and different cell types leading to microvascular injury, cellular necrosis, and apoptosis. The injury due to reperfusion is found predominantly in the intestinal mucosa and submucosa, causing endothelial detachment. The 21-aminosteroids (lazaroids) are a family of compounds that inhibit lipid membrane peroxidation. Many of the performed studies show conflicting results, which reflect differences in experimental design, evolving time that (I/R) is induced, total or partial vascular occlusion, dosage of the lazaroid, and the exact period of time that the lazaroid is administered. 相似文献

Objective
Hepatic ischemia/reperfusion injury (IRI) may cause acute inflammatory damage, producing significant organ dysfunction, an important problem for liver transplantation. Previous studies have demonstrated that Tetrandrine (Tet), a component of traditional Chinese herbal medicine, shows protective effects to scavenge active oxygen radicals and inhibit lipid peroxidation. In this study, we examined whether Tet has a protective effect on mouse hepatic IRI.Materials and Methods
Male C57BL/6 mice were divided into sham, ischemic, and Tet-treated groups; 90 minutes of warm ischemia was performed on the left liver lobe. Tet (20 mg/kg) was injected intraperitoneally at 1 hour before ischemia with a second intravenous dose was injected just before reperfusion. Blood and liver samples were collected at 6 hours after reperfusion. We analyzed the hepatocellular injury, oxidative stress, neutrophil recruitment, and tumor necrosis factor-alpha (TNF-α) generation associated with hepatic IRI.Results
Undergoing 90 minutes of ischemia and 6 hours reperfusion caused dramatic injuries in mouse livers. Administration of Tet (20 mg/kg) reduced serum levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), and lactate dehydrogenase (LDH); decreased liver edema, TNF-α, myeloperoxidase (MPO) and malondialdehyde (MDA) contents; and ameliorated the down-regulation of superoxide dismutase (SOD) activity.Conclusion
Tet showed protective effects on mouse hepatic IRI. 相似文献18.
BACKGROUND: The mechanism responsible for gastric colonization in critically injured ICU patients remains to be fully elucidated. Moreover, the effects of gut ischemia/reperfusion (I/R) injury on gastric function are unclear. It was our hypothesis that gut I/R injury would cause gastric dysfunction. MATERIALS AND METHODS: Rats were anesthetized and, via laparotomy, the superior mesenteric artery (SMA) was clamped at its aortic origin for 45 min followed by clamp removal. Rats were allowed to awaken and then killed after 6 h of reperfusion. Control rats underwent laparotomy with SMA isolation. Stomachs were removed, gastric fluid was aspirated, and the volume, pH, and protein, bicarbonate, and glucose contents were determined. Serum and antral mucosa were prepared for gastrin radioimmunoassay and the glandular mucosa was assessed for morphologic injury. RESULTS: SMA I/R injury caused significant accumulation of gastric luminal fluid that was alkaline and rich in protein, glucose, and bicarbonate content when compared with sham controls. SMA I/R injury also caused gastric surface epithelial cell injury and significantly increased serum and antral gastrin levels. In additional rats, gut I/R injury inhibited basal acid secretion and blunted the acid secretory response to pentagastrin. CONCLUSIONS: This study demonstrated for the first time that small intestinal I/R injury causes significant gastric dysfunction. The findings suggest that this type of injury, a frequent occurrence in critically injured ICU patients, may predispose patients to gastric colonization due to stasis and loss of the natural bactericidal effects of gastric acid. 相似文献

BACKGROUND: The effects of increased expression of intercellular adhesion molecule (ICAM-1), an important mediator of neutrophil-mediated reperfusion injury (RI), were assessed in donor cardiac allografts in a heterotopic rat transplantation model. METHODS: At -24 h, PVG donors were untreated (n = 35) or treated (n = 37) with lipopolysaccharide (LPS, 5 mg/kg ip). Hearts were procured at 0 h, stored at 4 degrees C for 45 min, and grafted heterotopically into ACI recipients pretreated with vehicle or anti-ICAM-1 (1A29) mAb. Intracardiac balloons (n = 8 per group) were used to measure allograft left ventricular function (dP/dt) prior to harvest and following reperfusion. RI was assessed at 6, 12, and 24 h by myeloperoxidase (MPO) levels, percentage wet weight (%w/w), and percentage contraction band necrosis (%CBN). RESULTS: At 12 h, LPS-pretreated grafts showed increased ICAM-1 expression by Northern blot (n = 3) and immunohistochemistry (n = 3) and significantly increased MPO (0.33 +/- 0.2 U/mg vs 0.05 +/- 0.04 U/mg at 12 h), %w/w (81.7 +/- 1.8% vs 79.2 +/- 0.7% at 12 h), and %CBN (15.2 +/- 1. 9% vs 11.4 +/- 2.0% at 24 h). LPS pretreatment had no effect on graft function at early time points (baseline to 2 h) but led to depressed dP/dt at later time points with trends toward significance at 12 h (2101 +/- 1653 mmHg/s vs 173 +/- 201 mmHg/s, P = 0.06, ANOVA). Recipient 1A29 treatment (n = 6 per group) reversed the effects of LPS pretreatment in all three RI parameters and significantly improved functional recovery. CONCLUSIONS: Alteration of cardiac graft phenotype to that likely seen in clinical organ donors leads to increased delayed-onset myocardial RI following transplantation in this model. The blockade of this increased RI following 1A29 mAb treatment supports a central role for ICAM-1 in this process. 相似文献
