Abstract
BACKGROUND A pig model has been commonly used for technical training for clinical liver transplantation (LT). However, as the healthy pigs have no shunt bypassing the portal vein (PV), it is necessary to complete LT within 30 minutes after shutting off the PV flow. While a model that uses an ex vivo shunt system has been used to alleviate the constraints of the anhepatic phase, it has been often difficult to keep sufficient blood flow rate and prevent the intestinal congestion because the blood vessels were occluded easily with the suction pressure by using the conventional shunt system. METHODS We designed a portable shunt system and a novel connector that can prevent the blood vessel from occluding. The system can separately control the flow rate of PV and inferior vena cava (IVC) and detect whether the blood vessels were occluded. By reducing the solution volume in the circuit, the effected blood loss ex vivo could be minimized. The stability of this system was verified with 15 medical doctors in an advanced medical professional education course. RESULTS The system enabled the blood flow to maintain ≥ 20 mL/minute and prevented the intestinal congestion. The perioperative hemodynamics of the recipient were stable without a blood transfusion using 25 to 40 kg pigs. We confirmed that all LT training were completed, even 60 minutes after shutting off the PV flow. CONCLUSIONS Our system greatly contributed to training on LT for conducting the survival experiments.

Adding the oxygen carrier M101 to a cold-storage solution could be an alternative to HOPE for liver graft preservation. JHEP Rep 2020; 2:100119. [PMID: 32695967 PMCID: PMC7364164 DOI: 10.1016/j.jhepr.2020.100119] [Citation(s) in RCA: 19] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/03/2020] [Revised: 04/20/2020] [Accepted: 04/21/2020] [Indexed: 12/16/2022] Open
Abstract
Background & Aims Hypothermic oxygenated machine perfusion (HOPE) is a promising technique for providing oxygen to the liver during graft preservation; however, because of associated logistical constraints, addition of an oxygen transporter to static cold-storage solutions (SCS) might be easier. M101 is marine worm haemoglobin that has been shown to improve kidney preservation in the clinic when added to SCS. This study evaluated the effects of the addition of M101 to SCS on the quality of pig liver graft preservation. Methods Pig liver grafts were preserved using SCS, HOPE, or SCS+M101, and the liver functions were compared during cold preservation and after orthotopic allotransplantation (OLT) in pigs. Results During preservation of the liver grafts, mitochondrial function, ATP synthesis, antioxidant capacities, and hepatocyte architecture were better preserved, and free radical production, antioxidant activities, and inflammatory mediators were lower, with HOPE or SCS+M101 than with SCS alone. However, after 1 h of preservation, liver functions with HOPE were superior to those with SCS+M101. After 6 h of preservation and OLT, blood levels of aspartate and alanine aminotransferases and lactate dehydrogenase increased with a peak effect at Day 1 post-transplant; values were similar with HOPE and SCS+M101, and were significantly lower than those in the SCS group. At Days 1 and 3, tumor necrosis factor α levels remained lower with HOPE and SCS+M101 vs. SCS. At Day 7, liver cell necrosis and inflammation were less marked in both oxygenated groups. Conclusions When added to SCS, M101 effectively oxygenates liver grafts during preservation, preventing post-transplant injury; although graft performances are below those achieved with HOPE. Lay summary When transported between donors and recipients, even cold-stored liver grafts need oxygen to maintain their viability. To provide them with oxygen, we added a marine worm super haemoglobin (M101) to the cold-storage solution UWCS. Using a pig liver transplant model, we revealed that livers cold stored with UWCS+M101 showed improved oxygenation compared with simple cold-storage solutions, but did not reach the oxygenation level achieved with machine perfusion.

Abstract
BACKGROUND The development of treatment strategies to protect against ischemia-reperfusion injury (IRI) to livers is important not only for liver surgeries but also in regard to increasing the utilization of livers from marginal donors. In this study, we examined whether inhalational carbon monoxide (CO) therapy reduced IRI after a 45-min (min) warm ischemia (WI) in a miniature swine model. MATERIALS AND METHODS Six CLAWN miniature swine underwent a 45-min hepatic WI induced by clamping the portal vein and proper hepatic artery. Three animals were subjected to control conditions while the remaining three were treated with CO inhalation for a total of 345-min, including 120-min after reperfusion to maintain a concentration of CO-Hb under 15% (CO-treated group). IRI of the livers was evaluated by liver function tests, serum pro-inflammatory cytokines, and liver biopsies. RESULTS All controls had statistically significant increased levels of liver enzymes compared to the CO-treated group (p < 0.05). In controls, liver biopsies at 2 h after reperfusion showed marked histological changes including diffuse hemorrhage, congestion, necrosis, vacuolization, and neutrophil infiltration with apoptosis. In contrast, the CO-treated group showed less obvious or only minimal histological changes. Furthermore, increases in high-mobility group box 1, TNF-α, and IL-6 in sera that were induced by IRI in controls were markedly inhibited by the CO treatment. CONCLUSION We demonstrated that low-dose CO inhalation reduces hepatic warm IRI, potentially through downregulation of pro-inflammatory mediators and activation of anti-apoptotic pathways. To our knowledge, this is the first report demonstrating CO inhalation attenuated hepatic IRI following WI in a large animal model.

Abstract
BACKGROUND Control of warm ischemia (WI) lesions that occur with donation after circulatory death (DCD) would significantly increase the donor pool for liver transplantation. We aimed to determine whether a novel, oxygenated and hypothermic machine perfusion device (HMP Airdrive system) improves the quality of livers derived from DCDs using a large animal model. METHODS Cardiac arrest was induced in female large white pigs by intravenous injection of potassium chloride. After 60 minutes of WI, livers were flushed in situ with histidine-tryptophan-ketoglutarate and subsequently preserved either by simple cold storage (WI-SCS group) or HMP (WI-HMP group) using Belzer-MPS solution. Liver grafts procured from heart-beating donors and preserved by SCS served as controls. After 4 hours of preservation, all livers were transplanted. RESULTS All recipients in WI-SCS group died within 6 hours after transplantation. In contrast, the HMP device fully protected the liver against lethal ischemia/reperfusion injury, allowing 100% survival rate. A postreperfusion syndrome was observed in all animals of the WI-SCS group but none of the control or WI-HMP groups. After reperfusion, HMP-preserved livers functioned better and showed less hepatocellular and endothelial cell injury, in agreement with better-preserved liver histology relative to WI-SCS group. In addition to improved energy metabolism, this protective effect was associated with an attenuation of inflammatory response, oxidative load, endoplasmic reticulum stress, mitochondrial damage, and apoptosis. CONCLUSIONS This study demonstrates for the first time the efficacy of the HMP Airdrive system to protect liver grafts from lethal ischemic damage before transplantation in a clinically relevant DCD model.

Abstract
Aspartate transaminase (AST) and alanine transaminase (ALT) are measured following liver transplantation as indicators of hepatocellular injury. During a series of orthotopic liver allo-and xenotransplants, we observed that there was an increase in AST in all cases. The anticipated concomitant rise in ALT did not occur when a wild-type (WT) pig was the source of the liver graft, but did occur when a baboon or a genetically engineered (α1,3-galactosyltransferase gene-knockout [GTKO]) pig was the source of the graft. We hypothesized that the cience of Galα1,3Gal in GTKO pig livers may render pig hepatocytes similar to human and baboon hepatocytes in their response to hepatocellular injury. Reviewing the literature, after WT pig liver allotransplantation or xenotransplantation, in the majority of reports, although changes in AST were reported, no mention was made of changes in ALT, suggesting that there was no change in ALT. However, Ramirez et al. reported two cases of liver xenotransplants from hCD55 pigs, following which there were increases in both AST and ALT, suggesting that it is not simply the cience of expression of Galα1,3Gal that is the cause. We acknowledge that our observation is based on a small number of experiments, but we believe it is worth recording.

Abstract
The purpose of this prospective, nine-center, non-randomized study was to assess the efficacy and safety of Celsior preservation fluid in liver transplantation using unselected donors. As data comparing allograft outcomes following liver transplantation using Celsior and University of Wisconsin (UW) preservation fluids are limited, we also compared our cohort with matched controls selected from the European Liver Transplant Registry (ELTR) who received total liver grafts preserved with UW solution during the same period. One hundred and forty patients who received livers preserved with Celsior were included. The primary endpoint, graft loss at one-yr post-transplantation, was observed in 24 patients (17.1%) which was not significantly different from the 20.0% pre-defined threshold rate (95% confidence interval [CI] 10.9, 23.4; p=0.398). Predictive factors for graft loss on univariate analysis were moderate-to-severe steatosis on the donor graft (5/22 patients with graft loss vs. 8/107 patients without, p=0.046) and duration of warm ischemia (1.4±1.1 h in patients with graft loss vs. 0.9±0.5 h in patients without, p=0.034). Hepatic artery thrombosis and stenosis occurred in seven (5.0%) and six (4.3%) patients, respectively. The comparison of our patients to 420 ELTR controls showed that one-yr graft survival rates (Celsior: 82.9%, 95% CI 75.8, 88.2; UW: 78.6%, 95% CI 74.4, 82.2) and Kaplan-Meier one-yr graft survival distributions (p=0.285) were similar. Within the cold ischemia time achieved in our study, liver preservation with Celsior appeared efficient and safe. Comparison with ELTR patients suggested that liver allograft survival was similar using Celsior or UW solution for preservation of unselected donor grafts.

Abstract
INTRODUCTION Orthotopic liver transplantation (OLT) is today the gold standard treatment of the end-stage liver disease. Different solutions are used for graft preservation. Our objective was to compare the results of cadaveric donor OLT, preserved with the University of Wisconsin (UW) or Celsior solutions in the portal vein and Euro-Collins in the aorta. METHODS We evaluated retrospectively 72 OLT recipients, including 36 with UW solution (group UW) and 36 with Celsior (group CS). Donors were perfused in situ with 1000 mL UW or Celsior in the portal vein of and 3000 mL of Euro-Collins in the aortia and on the back table managed with 500 mL UW or Celsior in the portal vein, 250 mL in the hepatic artery, and 250 mL in the biliary duct. We evaluated the following variables: donor characteristics, recipient features, intraoperative details, reperfusion injury, and steatosis via a biopsy after reperfusion. We noted grafts with primary nonfunction (PNF), initial poor function (IPF), rejection episodes, biliary duct complications, hepatic artery complications, re-OLT, and recipient death in the first year after OLT. RESULTS The average age was 33.6 years in the UW group versus 41 years in the CS group (P = .048). There was a longer duration of surgery in the UW group (P = .001). The other recipient characteristics, ischemia-reperfusion injury, steatosis, PNF, IPF, rejection, re-OLT, and recipient survival were not different. Stenosis of the biliary duct occured in 3 (8.3%) cases in the UW group and 8 (22.2%) in the CS (P = .19) with hepatic artery thrombosis in 4 (11.1%) CS versus none in the UW group (P = .11). CONCLUSION Cadaveric donor OLT showed similar results with organs preserved with UW or Celsior in the portal vein and Euro-Collins in the aorta.

Abstract
University of Wisconsin solution (UWS) is the gold standard for graft preservation. Celsior solution (CS) is a new solution not as yet widely used in liver grafts. The aim of this study was to compare the liver function of transplanted grafts stored in these 2 preservation solutions. The primary endpoints were the rates of primary nonfunction (PNF) and primary dysfunction (PDF). We performed a prospective and pseudorandomized study that included 196 patients (representing 104 and 92 livers preserved in UWS and CS, respectively) at La Fe University Hospital (Valencia, Spain) between March 2003 and May 2005. PNF and PDF rates, liver function laboratory parameters, postoperative bleeding, vascular and biliary complications, and patient and graft survival at 3 years were compared for the 2 groups. The 2 groups were similar in terms of donor variables, recipient variables, and surgical techniques. The PNF rates were 2.2% and 1.9% in the CS and UWS groups, respectively (P = not significant), and the PDF rates were 15.2% and 15.5% in the CS and UWS groups, respectively (P = not significant). There were no significant differences in the laboratory parameters for the 2 groups, except for alanine aminotransferase levels in month 3, which were lower in the CS group (P = 0.01). No significant differences were observed in terms of complications. Three-year patient and graft survival rates were as follows for years 1, 2, and 3: 83%, 80%, and 76% (patient) and 80%, 77%, and 73% (graft) for the UWS group and 83%, 77%, and 70% (patient) and 81%, 73%, and 67% (graft) for the CS group (P = not significant). In conclusion, this study shows that CS is as effective as UWS in liver preservation.

Abstract
Hypothermic machine perfusion (HMP) provides better protection against ischemic damage of the kidney compared to cold-storage. The required perfusion pressures needed for optimal HMP of the liver are, however, unknown. Rat livers were preserved in University of Wisconsin organ preservation solution enriched with acridine orange (AO) to stain viable cells and propidium iodide (PI) to detect dead cells. Perfusion pressures of 12.5%, 25% or 50% of physiologic perfusion pressures were compared. Intravital fluorescence microscopy was used to assess liver perfusion by measuring the percentage of AO staining. After 1-h, the perfusion pressure of 12.5% revealed 72% +/- 3% perfusion of mainly the acinary zones one and two. The perfusion pressure of 25% and 50% showed complete perfusion. Furthermore, 12.5% showed 14.7 +/- 3.6, 25% showed 3.7 +/- 0.9, and 50% showed 11.2 +/- 1.4 PI positive cells. One hour was followed by another series of experiments comprising 24-h preservation. In comparison with 24-h cold-storage, HMP at 25% showed less PI positive cells and HMP at 50% showed more PI positive cells. In summary, perfusion at 25% showed complete perfusion, demonstrated by AO staining, with minimal cellular injury, shown with PI. This study indicates that fine-tuning of the perfusion pressure is crucial to balance (in)complete perfusion and endothelial injury.

Abstract
AIM: To compare, in a pig liver transplantation model, the protective effect of UW with that of IGL-1, a high-sodium preservation solution containing polyethylene glycol (PEG) as an oncotic supply.
METHODS: All livers were harvested and grafted orthotopically according to standard techniques. The livers were washed out and preserved for 7 h in IGL-1 (n = 6) or in UW solution (n = 7) at 4°C. In a sham group (n = 4), the livers underwent a 60-min warm ischemia at 37°C. The hepatocellular injury was assessed in organ preservation solution washed out from the graft at the end of ischemic storage (before revascularization), and in serum 2 h after reperfusion and daily for up to 6 d.
RESULTS: Livers preserved in IGL-1 solution released markedly less AST than that preserved in the UW solution before and after revascularization (P < 0.05). Besides, the activity of creatine kinase-BB, a marker of sinusoidal lining cells injury, was higher in the UW group than in the IGL-1 group (P < 0.05). Histological results showed less necrotic regions in livers preserved in IGL-1 solution; however, no difference was observed for inflammation.
CONCLUSION: IGL-1 liquid effectively protects parenchymal and non-parenchymal cells against prese-rvation-reperfusion injuries.

Abstract
Two or three different solutions may be used to preserve thoracic and abdominal organs during a single procurement. The aim of this prospective, multi-center, noncomparative study was to evaluate the safety and efficacy of Celsior (study solution, solution S) as a flushing and cold storage solution for both thoracic and abdominal organs. Between August 1999 and July 2000, 72 consecutive multiple-organ procurements were performed using solution S as the sole solution for flushing out and cold-storing thoracic and abdominal grafts. Two hundred and sixty-four grafts were implanted into 245 recipients (131 kidneys, 9 kidney-pancreases, 69 livers, 34 hearts and 6 heart-lungs). The mean cold ischemia time was 21 h for kidneys (26%>24 h); 11 h 26 min for pancreases, 9 h 16 min for livers (23%>12 h), and 2 h 58 min for hearts and lungs. No cardiac failure or arrhythmia occurred on graft reperfusion. Fourteen percent of kidney recipients had delayed graft function. The mean serum creatinine level at 3 months was 123 +/- 41 micromol/l. All pancreas recipients were insulin-free at 3 months. Primary graft nonfunction occurred in one liver recipient. Complete hepatic artery thrombosis occurred in six liver recipients during the first month; four of these patients had a risk factor for thrombosis. All but three of the heart recipients were in sinus rhythm on day 1, and 65% were extubated on day 1. Inotropic drugs were necessary during the first 72 h in 25% of heart recipients. Twelve-month patient and graft survival rates were, respectively, 100% and 96% (kidney), 100% and 89% (pancreas), 88% and 83% (liver), 77.5% (heart) and 67% (heart-lung). These results suggest that Celsior, a ready-to-use solution, is safe and effective for multiple organ procurement and preservation.

Abstract
BACKGROUND Our aim was to investigate the potential of the preservation solution Celsior to protect rat cremaster muscle microcirculation during ischemia and reperfusion, and to compare its effects with those of HTK (histidine-tryptophan-ketoglutarate-Bretschneider solution). Because of its anti-oxidant contents, we expected Celsior to be more protective than HTK. MATERIALS AND METHODS Capillary perfusion and leukocyte-endothelium interactions were examined in rat cremaster muscle using intravital microscopy. After perfusion with Celsior or HTK (4 degrees C), the cremaster was subjected to 4 or 6 h of warm (33-34 degrees C) ischemia and 2 h of reperfusion. Measurements were performed prior to perfusion and/or ischemia, and 0, 1, and 2 h after restoration of flow. RESULTS Without Celsior or HTK, capillary perfusion transiently decreased to 50% of baseline after 4 h of ischemia; it remained low (45%) after 6 h of ischemia. Whereas HTK had no significant influence, Celsior deteriorated capillary perfusion: it remained low after 4 h of ischemia (39-48%) and decreased even further after 6 h of ischemia (18-8%). Both preservation solutions similarly reduced the increase in leukocyte-endothelium interactions after ischemia. CONCLUSIONS Preischemic tissue perfusion with Celsior had an adverse effect on capillary perfusion in rat cremaster muscle after 4 and 6 h of ischemia, whereas HTK did not significantly influence this parameter. Both preservation solutions similarly prevented the increase in leukocyte-endothelium interactions after ischemia. These data suggest that HTK is more suited as a preservation solution for muscular tissue than Celsior, especially when the known protective effects of HTK on muscle function are taken into account.

Abstract
BACKGROUND Viaspan (University of Wisconsin [UW]) solution is the gold standard for abdominal organ preservation. Celsior (CEL) is an extracellular-type, low-potassium, low-viscosity solution, initially used for heart and lung preservation. We have performed a prospective multicenter study to compare the role of these cold-storage solutions on kidney and liver recovery after transplantation. PATIENTS AND METHODS From March 15, 2000 to December 31, 2001, 441 (172 CEL and 269 UW) renal transplants (RT) and 175 (79 CEL and 96 UW) liver transplants (LT) were included in the study. RESULTS Perfusate volume used was significantly lower in the UW group, being 4,732 +/- 796 mL versus 5,826 + 834 mL in the CEL group (P < 0.001). In LT, median total bilirubin serum levels were significantly higher at 5 and 7 posttransplant days in the UW group (90.6 and 92.3 micromol/L, respectively) as compared with CEL (51.3 and 63.4 micromol/L, respectively). After LT, primary nonfunction (PNF) rates in the CEL and UW groups were 3.8% and 4.2% (P = NS) respectively, with 1-year graft and patient survival being 83.3% versus 85.4% (P = NS) and 89.9% versus 90.6% (P = NS). After RT, delayed graft function (DGF) rates were 23.2% and 22.7% (P = NS), respectively; PNF rates were 1.9% and 1.7% (P = NS) respectively, with 1-year graft and patient survival being 92.3% versus 94.2% (P = NS) and 99.4% versus 97.7% (P = NS). CONCLUSIONS CEL solution was shown to be as effective as UW in both liver and kidney preservation. In LT patients, biliary function recovery is significantly better in the CEL group. CEL solution represents an efficacious option in multiorgan harvesting.

Abstract
Availability of donor livers and the relatively short preservation time limit the success of liver transplantation. The use of hypothermic machine perfusion could pave the way for expansion of the donor pool. To better define optimal settings of such a device, the feasibility of using a numerical simulation model of the hepatic circulation is determined. Hemodynamics in the hepatic arterial, portal venous and hepatic venous compartments of the hepatic vascular tree was modelled using an electrical analogue. Calculated pressure and flow profiles throughout the liver were in accordance with physiologic profiles in the total circulatory system. Comparison of calculated flow values with normal control values showed a discrepancy that was explained by inaccurate diameter input data. Until more precise methods for determining vascular dimensions become available, redefining vessel diameter makes the simulation model perfectly suitable for predicting influences of temperature and/or viscosity on hepatic hemodynamics and is thereby an excellent tool in defining optimal settings for our hypothermic liver perfusion system.

Abstract
Serum-free preservation media such as University of Wisconsin (UW) may cause tissue damage through trophic factor (TF) deprivation. This study evaluated whether the addition of TFs to UW solution improves liver graft quality after extended cold preservation time in pigs. UW solution was supplemented with epidermal growth factor, insulin-like growth factor-1, nerve growth factor-beta, bactenecin, and substance P to create TF-supplemented (TFS) UW. Orthotopic liver transplantation was performed after 18 hr of static cold storage at 4 degrees C in UW (n=7) or TFS-UW (n=7) solution. Recipients of grafts preserved with TFS-UW demonstrated significantly better 5-day survival (57%) than those preserved with UW alone (14%) (P<0.05). Adenosine triphosphate content in grafts preserved in TFS-UW was significantly higher than in grafts preserved in UW (17.4+/-5.0 vs. 4.8+/-1.2 nmol/mg protein, respectively) (P<0.05). This study showed that the addition of TFs to UW solution allowed a significant extension of cold ischemic time in pigs.

Abstract
Primary dysfunction (PDF) still occurs after orthotopic liver transplantation (OLT). Celsior solution (CS) might offer some advantages over the conventional University of Wisconsin (UW) solution for organ preservation, but to date, this has not been prospectively evaluated in the context of OLT. In this prospective, randomized, multicenter, pilot study, 215 potential liver donors were enrolled and randomized. In 42 cases, the livers were unsuitable for transplantation; therefore, 173 randomized livers ultimately were implanted after perfusion and cold preservation with CS (n = 83) or UW solution (n = 90). In accord with the indications of the CS manufacturing company, total CS infusion volume was 90 mL/kg, greater than that of UW solution (60 mL/kg). The main aim of the study is to compare the prevalence of PDF between the two groups. Donor and recipient variables were similar in the two groups. Episodes of PDF were numerically lower in the CS (2.4%) than UW group (7.8%), but the difference was not statistically significant. There was a trend toward a lesser need for early re-OLT (<30 days) in the CS group (P =.0507), but again, no statistically significant difference emerged. Overall and time-differentiated postoperative deaths also were similar. One-year actuarial patient (UW, 89% v CS, 87%) and graft (UW, 83% v CS, 85%) survival rates were similar. In conclusion, CS was similar to UW solution as a preservation solution in the clinical setting of OLT at the infusion volumes described, although some theoretical advantages of CS composition suggest that CS might prove a valid alternative to UW preservation solution in multiorgan harvesting, including the liver. A study on a larger patient basis is needed.

Abstract
BACKGROUND The benefit of Celsior in liver graft preservation is controversial. In the isolated perfused rat liver model, we compared the effects of Celsior, University of Wisconsin (UW), and histidine-tryptophan-ketoglutarate (HTK) preservation solutions on liver cell death. METHODS Rat livers were stored at 4 degrees C for 0, 8, 16, or 24 hr in either Celsior, UW, or HTK and reperfused for 90 min (37 degrees C). Bile secretion and perfusate levels of liver enzymes and histone-associated DNA fragments were measured. Apoptosis and oncotic necrosis were analyzed in biopsies by DNA gel electrophoresis, hematoxylin and eosin histology, and enzyme histochemistry for lactate dehydrogenase (LDH) and 5'-nucleotidase (5'-NT). RESULTS Perfusate flow rate through the liver during perfusion did not significantly differ among preservation solutions. Bile secretion was best preserved in UW livers after 16-hr (versus HTK livers) and 24-hr storage (versus HTK and Celsior livers). Enzyme leakage from UW livers was lower compared with HTK livers after 8-hr storage (serum glutamic oxaloacetic transaminase [SGOT], LDH) and with Celsior and HTK livers after 16-hr (SGOT, LDH) and 24-hr storage (SGOT, serum glutamic pyruvic transaminase, LDH, purine nucleoside phosphorylase). In situ LDH and 5'-NT activities were best preserved in UW livers (up to 24 hr), whereas enzyme activities declined remarkably in HTK livers (after 8 hr) and Celsior livers (after 16 hr of cold storage). Although perfusate DNA fragment levels were repeatedly lowest from Celsior livers, apoptotic DNA laddering and the number of fragmented nuclei in hematoxylin and eosin sections was not different among livers after 8, 16, or 24 hr of storage. CONCLUSIONS Celsior and UW are equally effective in preventing rat liver cell death after 0-16 hr of cold preservation as compared with the less effective HTK solution. After 24-hr cold storage, rat livers were best preserved in UW. Furthermore, there was no significant difference in mode of cell death (apoptosis or oncotic necrosis) after storage in any of the three solutions.

Abstract
BACKGROUND The University of Wisconsin solution (UW) is the gold standard for pancreas preservation. Celsior (CEL) was formulated specifically for heart preservation. Recently, experimental and clinical experience has been reported on the application of CEL to abdominal organs. In this animal study, pancreas preservation with CEL was compared with that in UW solution. PATIENTS AND MATERIALS Heterotopic, allogeneic pancreaticoduodenal transplantation was performed in female Göttingen Minipigs (n = 12 donors, n = 12 recipients). The grafts were flushed and stored for 6 h at 4 degrees C in UW or CEL. The recipients were randomized into two groups receiving either UW (n = 6)- or CEL (n = 6)-preserved grafts with a follow-up of 5 days. Blood flow (laser Doppler), partial oxygen tension, histological changes, endothelin-1 (plasma, immunohistochemistry), lipase, amylase, trypsinogen activation peptide, and C-reactive protein (CRP) were measured. RESULTS Partial oxygen tension was lower in the CEL group (P < 0.05). However, blood flow did not differ between UW- and CEL-preserved organs. The histomorphologic analysis of the pancreatic grafts revealed significantly less edema in the UW-preserved organs. Serum levels of amylase, lipase, CRP, and TAP taken from the central venous blood were comparable in the two groups, except for higher amylase values 36 h after reperfusion in the CEL group compared to the UW group (P < 0.05). Likewise, TAP taken from the portal venous effluent of the graft was found to be higher in the CEL group than in UW (P < 0.05). Endothelin-1 serum levels rose significantly during reperfusion without differences between the two groups. ET-1 immunohistochemistry revealed increased local ET-1 during reperfusion in all grafts. However, the ET-1 immunostaining in the CEL group was more pronounced than that in the UW group (P < 0.05). CONCLUSIONS Our results suggest that CEL solution is not as effective in preventing pancreatic ischemia/reperfusion damage as the standard UW solution in experimental pancreas transplantation. Increased ET-1 immunostaining and reduced p(ti)O(2) in the CEL group indicate increased microcirculatory damage in the CEL group.

Abstract
BACKGROUND We evaluated the effects of standard preservation solutions on cultured human greater saphenous vein endothelial cells. METHODS Endothelial cells (eight strains) were preincubated for 6 or 24 hours at 4 degrees C in Celsior, Euro-Collins, St. Thomas Hospital II, and University of Wisconsin solutions, reincubated in warm oxygenated culture medium 199, and observed up to 48 hours. Culture viability was assessed through cell counting and confocal microscopy of calcein loaded cells. RESULTS Incubation in both Euro-Collins and St. Thomas, but not in Celsior or University of Wisconsin solutions, caused significant cells losses and diffuse morphological damages characterized by solution-specific distinctive alterations. Injury caused by 6-hour, but not by 24-hour treatment, was reversible. CONCLUSIONS The incubation with Celsior and University of Wisconsin solutions substantially preserved endothelial viability and proliferative capability. Conversely, a prolonged incubation in either Euro-Collins or St. Thomas solutions caused severe and potentially irreversible damage referable to the induction of, respectively, apoptotic or necrotic changes.

Abstract
BACKGROUND The optimal method for preserving livers from non-heart-beating donors (NHBD) is still unknown. We compared the Celsior solution, a new extracellular-type, low-potassium, low-viscosity preservation solution, with the University of Wisconsin (UW) solution in a canine orthotopic liver transplantation from NHBD. MATERIALS AND METHODS Fourteen adult mongrel dogs, weighing 9 to 17 kg, were divided into two groups: the Celsior or the UW group (n = 7 each). The thoracic descending aorta and supradiaphragmatic inferior vena cava were cross-clamped for 20 min to induce warm ischemia as a NHBD model. The liver was flushed with the respective cold preservation solution and then stored at 4 degrees C for 4 h. The grafts were transplanted using the piggy-back technique under portal decompression by leaving the native right lobe as a temporary shunt. RESULTS The duration of liver flushing out (min) was shorter (P < 0.05), and the serum glutamic oxaloacetic transaminase, glutamic pyruvic transaminase, lactate dehydrogenase, lactate, and alpha-glutathione S-transferase concentrations 2 and 6 h after reperfusion of the graft (RPF) were lower (P < 0.05) in the Celsior group than in the UW group. Hepatic tissue blood flow (HTBF) did not deteriorate as much (P < 0.05) in the Celsior group. The serum endothelin-1 level was lower (P < 0.05) in the Celsior group 2 h after RPF. Histopathology of liver specimens revealed portal congestion and hepatocyte necrosis with neutrophil infiltration in the UW group, while these findings were mild in the Celsior group. CONCLUSIONS The Celsior solution improves vascular endothelial injury in livers from NHBDs and may have advantages in graft flush and preservation of grafts from NHBDs.
