Abstract
PURPOSE/OBJECTIVE(S) Whilst standard treatment for intermediate-stage hepatocellular carcinoma (HCC) is transcatheter arterial chemoembolization (TACE), those exceeding "up-to-seven" criteria don't respond as such as those within, and systemic therapy is suggested to be more beneficial. This is sought to be both because of the limited efficacy of TACE and its hepatic toxicity. Proton beam therapy (PBT) offers high local control and low toxicity rates, and we hypothesize that the same can be said in this patient group also. We here present the outcome of PBT for primary HCC exceeding "up-to-seven" criteria. MATERIALS/METHODS Primary HCC treated with PBT between 2010 and 2018 were extracted from an all-in treatment database and retrospectively reviewed. (Maximum diameter of the largest tumor in centimeters) + (tumor count) > 7 was considered as exceeding "up-to-seven" criteria. Local recurrence was defined as tumor re-enlargement or the appearance of arterial phase hyperenhancement. Adverse events were evaluated by CTCAE v5.0. Overall survival and recurrence-free survival were determined by the Kaplan-Meier method, and local recurrence was analyzed as cumulative incidence with death as a competing risk. All statistical analyses were done using R. RESULTS Out of 202 primary cases, 79 exceeded the "up-to-seven" criteria. The median tumor diameter was 8.0 cm (range 3.1 - 20 cm) and macroscopic vascular invasion (MVI) was observed in 26 cases. For tumor count, 36 were solitary, 28 were between 2 - 3, and 15 had 4 or more. According to the modified ALBI grade, 38 were grade 1, 18 were grade 2a and 23 were 2b. The prescribed dose was 66 Gy / 10 Fr for 6, 72.6 Gy / 22 Fr for 60, 74 Gy / 37 Fr for 12 and 60 Gy / 15 Fr for one case after relative biological effect weighting of 1.1. With a median follow-up period of 33 months (IQR 15 - 57 months), 2-year overall survival was 62% (95% C.I. 50 - 72%) and median survival time was 37 months (95% C.I. 30 - 52 months). 2-year recurrence-free survival and local recurrence rate were 42% (95% C.I. 30 - 53%) and 8% (95% C.I. 3 - 15%) respectively. Cox regression analysis revealed modified ALBI grade as the only significant risk factor for survival (hazard ratio 1.80, 95% C.I. 1.27 - 2.55, p = 0.0010) among age, sex, alpha-fetoprotein level, MVI, tumor count, and size. Other than one case of early death (2 weeks after treatment) with an unknown causal relationship, there were no adverse events of grade 4 or higher observed. CONCLUSION PBT for primary HCC exceeding "up-to-seven" criteria appears to be safe and effective. Local control of intrahepatic lesions may be beneficial even in intermediate-stage cases, while results of this study suggests that suppression of out-of-field recurrence is required for further survival prolongment.

Abstract
PURPOSE/OBJECTIVE(S) Transcatheter arterial chemoembolization (TACE) is the standard treatment for early to intermediate-stage hepatocellular carcinoma (HCC) unfit for hepatectomy or radiofrequency/microwave ablation (RFA/MWA). Putting aside its hepatic toxicity, local control of TACE is far from satisfactory, especially with non- "simple nodular type" appearances, to an extent where systemic therapy is suggested to be more beneficial. We here analyzed the outcome of proton beam therapy (PBT) for primary HCC by macroscopic classification. MATERIALS/METHODS Primary HCC treated with PBT between 2010 and 2018 were extracted from an all-in treatment database. The macroscopic classification was defined by CT or MRI prior to PBT. Local recurrence was defined as tumor re-enlargement or the appearance of arterial phase hyperenhancement. Adverse events were evaluated by CTCAE v5.0. Overall survival, local control, intrahepatic recurrence-free survival, and extrahepatic recurrence-free survival were determined by the Kaplan-Meier method, and the association with treatment factors was analyzed by log-rank and cox regression model. RESULTS A total of 202 primary HCC cases were extracted, all not a candidate for hepatectomy nor RFA/MWA. Out of them, 75 cases were simple nodular type, 79 were simple nodular type with extranodular growth, 38 were confluent multinodular type, and 10 were infiltrative type. 26 cases were HBV positive, and 84 cases were HCV positive. 35 cases had macroscopic vascular invasion (MVI). With a median follow-up period of 3.72 years (IQR: 1.79-5.85years), the 3-year overall survival rate was 68.1% (95% CI 61.0 - 74.3%), the 3-year local control rate was 89.6% (95% CI 83.4-93.5), the 3-year intrahepatic recurrence-free survival rate was 53.7% (95% CI 45.9-60.8%), and the 3-year extrahepatic recurrence-free survival rate was 87.4% (95% CI: 81.5-91.6%). Simple nodular type had better overall survival (73.2% vs 65.2% p = 0.012) and extrahepatic recurrence free survival (96.9% vs 81.9% p<0.01), but there was no statistically significant difference in local control (92.7% vs 87.6% p = 0.06) and intrahepatic recurrence-free survival (62.0% vs 48.5% p = 0.114). Multivariate analysis of risk factors against OS, including age, sex, AFP, MVI, and macroscopic classification, revealed age and macroscopic classification as independent risk factors. Adverse events of grade 3 included 2 cases of gastrointestinal bleeding, 7 cases of liver function disorder, 1 cases of biliary hemorrhage, and 1 case of pleural effusion. Other than one case of early death (2 weeks after treatment) with an unknown causal relationship, there were no adverse events of grade 4 or severe. CONCLUSION PBT for non- "simple nodular type" primary HCC appears to be safe and effective, whilst suppression of out-of-field recurrence is needed for further survival prolongment.

Abstract
INTRODUCTION Adeno-carcinomas of pancreatic body are usually asymptomatic and progress to advanced stage with involvement of major arteries. Resection of advanced cancer along with en bloc resection of a common hepatic artery and celiac trunk enables a "curative" resections and only possible treatment. However, the celiac axis resection always has a risk of compromising blood supply to liver, resulting in the hepatic insufficiency. We evaluated practicability of a two-stage procedure for the advanced pancreases body cancer, laparoscopic clamping of a common hepatic artery followed by open distal pancreatectomy with en bloc celiac arterial resection to prevent the hepatic insufficiency. MATERIALS AND SURGICAL TECHNIQUE Seventy-five-year-old woman diagnosed with a 50-mm pancreatic body mass, invading splenic artery, common hepatic artery, splenic vein, and portal vein at the confluence. STAGE-1: At laparoscopy, after confirming absence of the peritoneal, superficial liver metastases and negative peritoneal cytology; we approached the common hepatic artery through the lesser sac and ligated. STAGE-2: Her liver function tests were normal after 2 weeks, and CT angiography showed complete blockage of the common hepatic artery with sufficient collateral circulation to the liver through inferior pancreatico-duodenal artery and gastro-duodenal artery. We performed an open distal pancreatectomy with en bloc resection of celiac artery. Histopathology examination confirmed R0 resection. DISCUSSION The celiac axis resection with distal pancreatectomy improves the chance of R0 resection and potentially, survival of the patient. Preoperative laparoscopic ligation of the common hepatic artery is a safe, effective, and in-expensive technique to prevent postoperative hepatic insufficiency and improves the safety of en bloc celiac artery resection with a distal pancreatectomy. Also these patients have high risk of peritoneal dissemination. Diagnostic laparoscopy is useful to detect occult metastasis, which are missed by per-operative CT scan.

Abstract
Pseudocysts and post-necrotic collections of the pancreas are sometimes treated by percutaneous drainage. In cases of post-necrotic collection, intractable pancreatic juice fistula is often formed by disruption of the main pancreatic duct in the necrotized region. We radically treated intractable pancreatic juice fistulae by selective cannulation into the distal pancreatic duct via the route for percutaneous drainage of post-necrotic collections to extinguish the exocrine function of the caudal pancreas. We performed this procedure in two patients in whom the major pancreatic duct was damaged at the body of the pancreas, which was extensively necrotic. Although mild symptoms of acute pancreatitis appeared in both patients after the first procedure, they recovered without severe side effects. Neither recurrence of pancreatic juice fistulae nor reduction of the glucose tolerance was caused by removing the exocrine function of the caudal pancreas in either patient 32 and 24 months after treatment, respectively. This method is an effective treatment modality with which to treat intractable pancreatic juice fistulae with damage of the main pancreatic duct.

Abstract
OBJECTIVE alpha-fodrin is a recently identified autoantigen associated with adult primary Sjögren's syndrome (SS). We tested whether anti-alpha-fodrin antibody could also be used as a diagnostic marker for childhood SS. METHODS We performed immunoblot analysis of sera from 7 patients with childhood primary SS using glutathione-S-transferase alpha-fodrin fusion protein as an antigen. RESULTS Anti-alpha-fodrin antibody was detected in sera from all 7 patients with childhood primary SS, 2 of 4 with secondary SS, and one of 7 with systemic lupus erythematosus, but in no other healthy controls. CONCLUSION The anti-alpha-fodrin autoantibody was detected before anti-SSA or SSB antibody became positive; thus anti-alpha-fodrin antibody could be a useful marker for the early diagnosis of SS.

Abstract
The validity and reliability of research on the nature and extent of sexual assault tends to be affected by different definitions, methodologies, and measurements. As a result, two important aspects of sexual assault associated with patterns of symptom expression and therapeutic interventions are not often reflected in the research; the severity of the assault, including the duration of the abuse, and the age at the time of the assault and the gender of the victim. This research is based on intake forms from Hawai;i's only statewide provider of services to the victims of sexual assault. The analyses reveal that significant differences exist between male and female victims, by age and by assault characteristics, including the type of sexual assault, use of force and injury, length of assault, and the relationship between victim and offender.

Abstract
The major goal in cancer immunotherapy is the induction of tumor-specific T lymphocytes capable of killing tumor cells. As both dendritic cells (DCs) and interleukin-12 (IL-12) can play immunostimulatory roles in vivo, the use of a combination of these has become a promising approach. In the present study, we used a murine tumor model to examine whether spleen-derived DCs transduced with the IL-12 gene could elicit tumor-specific immune responses. BALB/c mice injected peritumorally with adenovirus-mediated IL-12 gene-transduced antigen-unpulsed DCs inhibited the growth of day 5-established subcutaneous CT26 tumors. Splenocytes from treated mice responded specifically to parental tumor cells and showed increased production of interferon gamma (IFN-gamma) and antitumor cytotoxic T-lymphocyte (CTL) activity. Increased numbers of both CD4(+) and CD8(+) T cells were detected in the treated tumors. The inhibition of tumor growth was significantly greater in mice injected with IL-12 gene-transduced DCs than in those injected with IL-12 gene-transduced fibroblasts or the IL-12 gene-encoding adenovirus itself. Taken together, these results indicate that DCs transduced with the IL-12 gene by a recombinant adenovirus are effective in inducing tumor-specific Th1 and CTL responses that inhibit the growth of established subcutaneous tumors.

Abstract
Many studies have reported a close association between VEGF and tumor angiogenesis. The aim of the present study was to evaluate the effectiveness of gene therapy against cancer, including peritoneal metastasis, using a cDNA encoding a soluble type of Flt-1, one of the VEGF receptors. In a peritoneal metastasis model of MKN45 human gastric cancer cells, mice repetitively treated with intraperitoneal injections of HVJ-Fex, a type of HVJ-cationic liposome encapsulating a plasmid expressing soluble mFlt-1, exhibited smaller disseminated foci with fewer microvessels, thus resulting in a significantly longer survival period than the control mice. In another peritoneal metastasis model using HT1080S cells, a clone of HT1080 human fibrosarcoma cells stably transfected with hVEGF, treatments with HVJ-Fex also reduced the growth of disseminated foci without ascites formation. In conclusion, this study demonstrated that the peritoneal metastases of some cancers were largely dependent on VEGF, and that the repeated intraperitoneal transduction of a soluble flt-1 gene using HVJ-cationic liposomes suppressed peritoneal metastases, thereby contributing to a longer survival period.

Abstract
Mouse macrophage metalloelastase (MME) has been associated with the generation of angiostatin, an internal fragment of plasminogen, which inhibits angiogenesis. To clarify whether tumor cells that consistently generate MME can suppress angiogenesis and, therefore, inhibit the growth of primary tumors in vivo, we transfected a cDNA coding for MME into murine B16-BL6 melanoma cells that grow rapidly and are MME deficient. The generation of active MME in MME-transfected clones was confirmed by immunoprecipitation followed by in vitro cleavage of plasminogen. Subcutaneous implantation of these stable clones in C57BL/6 mice inhibited primary tumor growth by an average of 73% (P = 0.00002), which directly correlated with a significant reduction of blood vessel formation (approximately 76%) in such tumors. Microangiography revealed massive angiogenesis in control tumors (mock and vector); however, in MME-transfected primary tumors it demonstrated a decreased and disrupted vascular network. Western blot analysis using a specific anti-mouse angiostatin antibody demonstrated a strong 38-kDa immunoreactive band in MME-transfected tumors and in the serum of mice bearing those tumor cells. These results show that placing MME gene directly into B16-BL6 melanoma cells is an effective approach to suppress primary tumor growth in vivo because it halts angiogenesis. Our data provide a feasible and promising strategy for gene therapy of cancer by targeting tumor vasculature.

Abstract
BACKGROUND It is well known that sinusoidal endothelial cell (SEC) damage during cold preservation of liver tissue is closely involved in early graft failure. The objective of this study was to investigate the involvement of apoptosis in the SEC damage induced by cold preservation and to demonstrate the protective effect of vascular endothelial growth factor (VEGF) on SEC injury, including apoptotic changes. METHODS Isolated SECs and liver tissue of Wistar rats were cold-preserved in University of Wisconsin (UW) solution, and the protective effect of VEGF was then investigated. Isolated SECs were cultured for 24 hr, and divided into the following 3 groups: Group A, in which the cells were cultured for an additional 27 hr, Group B, in which the cells were cold-preserved in UW solution for 3 hr, and then recultured for 24 hr, and Group C, in which 20 ng/ml of VEGF was added to both the culture medium and the UW solution of cells cultured according to the Group B protocol. Each group of SECs was morphologically examined using the phase contrast microscopic method and the transmission electron microscopic method (TEM), and quantitatively analyzed using the WST-1 assay. Rat livers were cold-preserved in UW solution and divided into the VEGF(+) group and the VEGF(-) group, depending on whether VEGF was added or not. Each group of livers were analyzed by scanning electron microscopic method (SEM) after 24 hr of preservation. The hyaluronic acid uptake rate (HUR) was also determined after 6 hr of preservation. After 24 hr of preservation and 6 hr of reperfusion, tissues were examined by TEM and by the terminal deoxynucleotidyl transferase d-uridine triphosphate nick end labeling (TUNEL) assay. RESULTS The phase contrast microscopic method and the WST-1 assay showed a protective effect of VEGF against the injury to isolated SECs during cold preservation and subsequent reculturing. Apoptosis was detected immediately by TEM after isolation of SECs, and the number of apoptotic cells increased with the incubation time. This increase was accelerated after cold preservation. The scanning electron microscopic method and the hyaluronic acid uptake rate showed a protective effect of VEGF against SEC damage in the cold-preserved livers. In the liver tissue, the TEM and the TUNEL assay detected apoptosis of SECs only after cold preservation and subsequent reperfusion. VEGF suppressed the apoptosis of SECs induced by cold preservation in both isolated cells and liver tissue. CONCLUSIONS We demonstrated that SEC damage in the cold preservation of liver tissue was caused mainly by apoptosis, which required subsequent reperfusion. Moreover, isolated SECs showed spontaneous occurrence of apoptotic changes during culture, and these changes were accelerated by the preceding cold preservation. This is the first report to demonstrate the apoptotic changes of SECs seen here were inhibited by VEGF.

Abstract
OBJECTIVE To determine molecular mechanisms involved in angiogenesis of hepatocellular carcinoma (HCC). SUMMARY BACKGROUND DATA Tumor angiogenesis is believed to derive from the balance between angiogenic stimulators and inhibitors. It has been suggested that the switch to the angiogenic phenotype requires both upregulation of the first and downregulation of the second. However, its molecular basis in vivo remains obscure. In this study the authors analyze the participation of two factors in angiogenesis of HCC- human macrophage metalloelastase (HME), a matrix metalloproteinase responsible for the generation of angiostatin, a potent angiogenesis inhibitor, and vascular endothelial growth factor (VEGF), the most potent endogenous angiogenic factor. METHODS Tumorous and contiguous nontumorous tissues from 25 patients with HCC who underwent curative partial hepatectomy were subjected to Northern blot analysis to detect HME and VEGF messenger RNA (mRNA) expression. Western blot analysis was used to detected angiostatin. Tumor vascularity was evaluated using hepatic angiography. RESULTS Eleven of the 15 cases expressing the HME gene showed hypovascular tumors, whereas hypervascular tumors were seen in 9 of the 10 HME-negative cases. The median of HME mRNA expression (tumorous/nontumorous ratio) was 6.5 (range 0-264.5) in the hypovascular group and 0 (range 0-3.2) in the hypervascular group. A stepwise logistic analysis revealed that HME and VEGF mRNA expression were two independent variables significantly affecting the vascularity of HCC tumors. CONCLUSION HME gene expression is significantly associated with hypovascular tumors; moreover, angiogenesis in HCC is not determined by a single factor, but depends on the net balance between HME and VEGF gene expressions.

Abstract
Vascular endothelial growth factor (VEGF) may affect the phenotype of cancer cells, such as growth velocity and metastatic potential, due to its probable multifunctional property including a mitogenic activity for vascular endothelial cells. The present study was designed to investigate the association of VEGF mRNA expression with progression and metastasis of human colorectal cancer. The level of VEGF mRNA expression was quantified by Northern blot hybridization in tumorous and non-tumorous tissues obtained from 60 primary colorectal cancer patients. The ratio of the former to the latter was defined as the VEGF T/N ratio, and the prognostic significance of this ratio, following surgery, in addition to the relationship to progression and metastatic potential, was evaluated. The value of the VEGF T/N ratio was significantly correlated with the depth of tumour infiltration (P=0.046), the incidence of liver metastasis (P < 0.0001) and lymph node metastasis (P=0.036). Patient prognosis was estimated by the Kaplan-Meier method and the log-rank test. When the VEGF T/N ratio was higher than 4.8 for which the chi2 value of the log-rank test was maximal, the tumour was defined as showing overexpression of VEGF mRNA. Patients with overexpression of VEGF mRNA demonstrated poorer survival than patients without overexpression of VEGF mRNA (P < 0.001). The overall estimated hazard ratio for death in patients with overexpression of VEGF mRNA was 1.94 according to a multivariate analysis (P=0.005). Thus, VEGF is associated with the progression, invasion and metastasis of colorectal cancer, and overexpression of VEGF mRNA in the primary tumour is assumed to be closely correlated with poor prognosis in colorectal cancer patients. Moreover, the VEGF T/N ratio may be used as an independent prognostic marker in colorectal cancer patients.

Macrophage metalloelastase, a member of the human matrix metalloproteinase family, is believed to play an important role in angiostatin generation, which, in experimental studies, has an antiangiogenic function and is a key molecule in tumor dormancy. However, no clinical studies have been reported regarding the correlation between human macrophage metalloelastase (HME) gene expression and angiostatin production. Therefore, the present study was designed to evaluate the HME messenger RNA (mRNA) expression and angiostatin generation in hepatocellular carcinoma (HCC). Tumorous and contiguous nontumorous tissues were obtained from 40 HCC patients who underwent curative partial hepatectomy. By using Northern blot hybridization, HME mRNA was detected in 25 of the 40 HCC samples and, in all of these cases, the expression in tumorous tissues was stronger than in the nontumorous tissues. In situ hybridization identified the HCC cells as mainly responsible for the signals shown in Northern blot. Angiostatin was detected by Western blot mainly in tumors and showed significant association with HME mRNA expression in tumorous tissues (P = .0008). The patients whose tumors did not express HME mRNA and, thus, did not produce angiostatin, demonstrated poorer survival than those whose tumors showed high expression of HME mRNA and angiostatin generation (P = . 002). The univariate and multivariate analyses revealed that HME mRNA expression is a new and independent variable affecting overall survival (P = .001 and P = .03, respectively). These findings show that the HME gene is expressed in HCC being significantly associated with angiostatin generation by such tumors and that HME mRNA expression may serve as a new molecular prognostic marker in HCC patients after partial hepatectomy.

Abstract
An expression vector for the luxAB genes, derived from Vibrio harveyi, was introduced into Nitrosomonas europaea. Although the recombinant strain produced bioluminescence due to the expression of the luxAB genes under normal growing conditions, the intensity of the light emission decreased immediately, in a time-and dose-dependent manner, with the addition of ammonia monooxygenase inhibitors, such as allylthiourea, phenol, and nitrapyrin. When whole cells were challenged with several nitrification inhibitors and toxic compounds, a close relationship was found between the change in the intensity of the light emission and the level of ammonia-oxidizing activity. The response of bioluminescence to the addition of allylthiourea was considerably faster than the change in the ammonia-oxidizing rate, measured as both the O2 uptake and NO2- production rates. The bioluminescence of cells inactivated by ammonia monooxygenase inhibitor was recovered rapidly by the addition of certain substrates for hydroxylamine oxidoreductase. These results suggested that the inhibition of bioluminescence was caused by the immediate decrease of reducing power in the cell due to the inactivation of ammonia monooxygenase, as well as by the destruction of other cellular metabolic pathways. We conclude that the assay system using luminous Nitrosomonas can be applied as a rapid and sensitive detection test for nitrification inhibitors, and it will be used to monitor the nitrification process in wastewater treatment plants.

Abstract
No consensus has been reached on the indications for and effectiveness of surgery for secondary intrahepatic hepatocellular carcinoma (HCC) and extrahepatic metastasis after macroscopically complete removal of primary HCC. Secondary intrahepatic HCCs, usually regarded as recurrence are classified into those arising as a result of multicentric carcinogenesis or intrahepatic metastases derived from the primary HCC. The present study was designed to evaluate the utility of surgical treatment in relation to the pathogenesis of the secondary HCC: classified as multicentric carcinogenesis (MC), intrahepatic metastasis (IM), and extrahepatic metastasis. Thirty patients underwent extirpation of secondary HCC: 22 patients had secondary HCCs in the remnant liver (MC group; n = 8; IM group, n = 14), 6 patients had extrahepatic metastases, and 2 patients had both intrahepatic and extrahepatic metastases. Survival rates after the re-resection in the 22 patients with the secondary intrahepatic HCCs were 94.7% at 1 year, and 50.2% at 3 years postoperatively, and the 8 patients with extrahepatic metastasis had survival rates of 62.5% at 1 year, 37.5% at 3 years, and at 5 years. The survival rates after re-resection in the MC group were 100% at 1 year and 80.0% at 3 years, whereas those in the IM group were 91.7% at 1 year, and 38.1% at 3 years. Surgery can be indicated not only in patients with localized intrahepatic secondary HCCs but also in those with extrahepatic metastasis. In particular, patients with secondary HCCs arising as a result of multicentric carcinogenesis are expected to have a good prognosis.

Abstract
To identify the intercellular signal-transducing proteins and receptors produced by cancer cells, we attempted to clone cDNAs encoding secreted and type I membrane proteins using a signal sequence trap (SST) method with some modifications. By screening an SST library derived from pancreatic cancer cells, we identified two secretory proteins (neutrophil gelatinase-associated lipocalin (NGAL) and lung surfactant protein D) and three membrane proteins (carcinoembryonic antigen, BiP/GRP78 and Hsa4 mitochondrion cytochrome oxidase subunit II). NGAL mRNA was expressed in eight of the pancreatic cancer cell lines and eight pancreatic cancer tissues. The expression of NGAL mRNA was also observed in colorectal and hepatic tumors.

Abstract
Recent studies have shown that Kupffer cell function is enhanced in the cold-preserved liver, and blockade of Kupffer cells attenuates the injury induced by cold preservation with subsequent reperfusion. This study was designed to investigate the contribution of Kupffer cell blockade with gadolinium chloride (GdCl3) to the rescue of sinusoidal endothelial cell (SEC) damage by comparing the time-related morphological and ultrastructural changes. GdCl3 injection reduced the number of Kupffer cells reactive with monoclonal antibodies ED2 and Ki-M2R directed against macrophage. Scanning electron microscopy revealed the prominent string-like appearance of the SEC processes at 24 hr of preservation in the control; the SECs were better preserved in the GdCl3-pretreated group. Transmission electron microscopy showed detachment of the sinusoidal epithelia at 12 hr of preservation in the control; it was not seen in the GdCl3-pretreated group. At 24 hr of preservation, the SECs were better preserved in the GdCl3-pretreated group. Microvascular casts from the control group showed a disturbance in the radial arrangement of the sinusoids, significant dilation of the sinusoidal caliber at 24 hr, and discontinuity of the sinusoids with extravasation of the casting material at 36 hr of preservation. These changes were also minimized in the GdCl3-pretreated group. In conclusion, the present study demonstrates that Kupffer cells are strongly involved in the morphological integrity of SECs and that blockade of the activation of Kupffer cells would be effective for the prevention of damage to SECs and maintenance of the sinusoidal architecture during cold preservation of the liver tissure.
