Abstract
BACKGROUND Magnetic compression anastomosis (MCA) is a revolutionary, minimally invasive method of performing choledochoenterostomy or choledochocholedochostomy without using surgical techniques in patients with biliary stricture or obstruction. Herein, we describe a case series of MCA for severe biliary stricture or obstruction, which could not be treated with conventional therapies. PATIENTS AND METHODS Two patients with biliary obstruction were treated using MCA for choledochocholedochostomy and choledochoenterostomy at Tokyo Medical University Hospital and Tokyo Medical University Hachioji Medical Center. Endoscopically, a samarium-cobalt (Sm-Co) rare-earth magnet was placed at the superior site of obstruction through the percutaneous transhepatic biliary drainage route and another Sm-Co magnet was placed at the inferior site of obstruction. A comprehensive computer-aided literature search for MCA was performed up to September 2009 by using MEDLINE and EMBASE. RESULTS MCA techniques enabled complete anastomosis in both cases without procedure-related complications. CONCLUSIONS The MCA technique is a revolutionary method of performing choledochocholedochostomy and choledochoenterostomy interventionally in patients with biliary obstruction, for whom the conventional endoscopic procedure is not available, or in candidates who are deemed unsuitable for surgery.

Abstract
Magnetic compression anastomosis (MCA) is a minimally invasive method of performing choledochocholedochostomy without surgery in patients with biliary stricture or obstruction. We describe a successful case involving magnetic compression duct-to-duct biliary reconstruction in right-lobe living donor liver transplantation (RL-LDLT). Endoscopically, a samarium-cobalt (Sm-Co) rare-earth magnet was placed at the superior site of obstruction via the percutaneous transhepatic biliary drainage route, and another Sm-Co magnet was also placed at the inferior site of obstruction with the aid of an endoscope. MCA techniques enabled complete anastomosis without procedure-related complications. In conclusion, the MCA technique is a revolutionary method of performing choledochocholedochostomy in patients with biliary obstruction after LDLT.

Abstract
BACKGROUND Portal vein tumour thrombosis is a negative prognostic factor for hepatocellular carcinoma (HCC). AIM To assess the efficacy of cisplatin in lipiodol emulsion combined with 5-fluorouracil (5-FU) for patients with HCC and portal vein tumour thrombosis. METHODS The study subjects were 51 patients with the above-specified criteria who received injection of cisplatin suspension in lipiodol emulsion followed by intra-arterial infusion of 5-FU. The primary objective was to determine tumour response to the treatment, while the secondary objectives were safety and tolerability. Independent factors for survival were also assessed. RESULTS Ten patients had complete response and 34 patients had partial response (response rate, 86.3%). The median survival for all 51 patients was 33 months, while that for 10 complete response patients and 21 patients who showed disappearance of HCC following additional therapies was 39 months. The single factor that significantly influenced survival was therapeutic effect. Treatment was well tolerated and severe toxicity was infrequent, with only grade 3 toxicity (thrombocytopenia) in one patient. CONCLUSIONS The present study demonstrated the efficacy of hepatic arterial infusion chemotherapy using cisplatin-lipiodol emulsion and 5-FU without serious adverse effects in patients with unresectable HCC and portal vein tumour thrombosis.

Abstract
BACKGROUND This study evaluated the usefulness of machine perfusion preservation parameters as selection criteria for donation after cardiac arrest (DCD) with high creatinine level. The aim of this study is to evaluate to whether DCD donor >50 years old and with high creatinine are acceptable. METHODS We examined 17 kidneys from uncontrolled DCD who showed creatinine levels >3.0 mg/dL before procurement. The study included the following two groups: group 1 (n = 9), donor age <50 years old versus group 2 (n = 8), donor age >50 years old. RESULTS There were no significant differences in donors or preservation conditions among the 2 groups, including age, terminal creatinine, warm ischemic time, cold perfusion time, and total ischemic time. A greater resistance of 47.9 mmHg/mL per min/g was observed among group 2, compared with 42.5 mmHg/mL per min/g in group 1. A shorter ATN period (8.2 days) was noted in group 1, compared with 21.2 days for group 2. The flow rate (mL/g/min) was not significantly different between the two groups. The best-Cr level was 1.22 mg/dL in group 1 and 1.94 mg/dL in group 2. CONCLUSION Machine perfusion flow was a reliable indicator of graft viability in uncontrolled DCD, particularly kidneys with high creatinine level. Even older donors were acceptable if the machine perfusion preservation parameters such as flow rate and pressure were acceptable; however, they may show severe delayed graft function.

Abstract
We investigated changes in drug disposition and toxicities with CPT-11 in 15 dialysis patients with gastrointestinal cancers to clarify whether CPT-11 could be administered safely in such patients. For comparison, the same parameters were also investigated in 10 cancer patients not undergoing dialysis. Items investigated included (1) plasma concentrations of SN-38, SN-38G and CPT-11 at 0, 1, 12, 24, 36, 48 and 72 h after administration, together with a comparison of mean AUC values for 3 dose levels of CPT-11 (50, 60 and 70 mg/m2) in dialysis patients and controls; and (2) occurrence of adverse events. Several findings emerged from this study: (1) No significant difference was observed in the AUC for SN-38 or CPT-11 between the dialysis and control groups; (2) The AUC for SN-38G at each dose was significantly higher in dialysis patients; and (3) Grade 1-4 leucopenia was observed in 11 of the dialysis patients. One patient developed grade 4 leucopenia and died due to sepsis. Anorexia, diarrhea, nausea, alopecia and interstitial pneumonia occurred in 6 dialysis patients. We found changes in drug dispositions of CPT-11, SN-38 and SN-38G in dialysis patients, suggesting that hepatic excretion, especially that of SN-38G, was increased. No significant difference in occurrence of adverse events was observed between the 2 groups. This indicates that CPT-11 can be administered safely in patients on dialysis.

Abstract
1. Various growth rates of chickens were induced with different nutritional regimes, and the collagen content and architecture of the medial part of the puboischiofemoralis muscle were compared among 21-d-old chicks and 80- or 95-d-old broilers. 2. The percentage muscle weight relative to live weight increased from chicks to 80-d-old broilers and the 95-d-old broilers attained the largest percentage. An inter-relationship of the percentage muscle weight and the growth rates of birds could not be determined. 3. Collagen concentration was related to the growth rates for the first 21 d post hatching and maintained the same level during the later stages up to 80 d. The 95-d-old broilers, that were subjected to early rapid growth followed by restricted later growth, had the highest collagen content. 4. On SEM (Scanning Electron Microscopy) photographs, endomysial honeycombs were small and encircled by perimysia of a collagen network with small mesh size. Thin and thick perimysia were distinguished and the expanded portion of thick perimysia was also observed. Generally, the perimysia were made up of rough collagen tissue where fatty tissue developed, especially in the broilers. 5. Perimysial collagen fibres with mainly transverse striation were divided into two fundamental types, wide collagen platelets and narrow cords. With growth from the chick to broiler stage, features of the collagen fibres did not change regardless of expansion of the thick perimysia. Endomysia increased slightly from thin to thick meshwork as growth progressed. However, the collagen architecture of the muscle in broilers did not change under different nutritional regimes. 6. In conclusion, the puboischiofemoralis muscle of chickens develops relative to live weight when later growth is limited in broilers, but the collagen architecture is not affected by the different growth rates.

Abstract
1. Varying growth rates in chickens were induced by different nutritional regimes. The collagen content and architecture of iliotibialis lateralis (ITL) muscle were compared among 21-d-old chick types and broiler types at 80 or 95 d of age. 2. Relative size of ITL muscle was greater in the rapid growing (1.16% of live weight) than the slow growing chicks (1.02% of live weight). The 80-d-old broilers with a compensatory growth phase after an earlier slow growth period produced ITL muscle at 1.65-1.69% of live weight. The ITL muscle in 80- and 95-d-old broilers with restricted later growth after an earlier rapid growth period was 1.29 and 1.49% of live weight, respectively. 3. Collagen content of ITL muscle did not differ between chick types and also among the broiler types. However, collagen concentration decreased from 6.00-6.51 mg/g in the chicks to 3.33-4.00 mg/g in the broilers. 4. Thick and thin perimysia and honeycomb endomysia were viewed by scanning electron microscope (SEM) photography. In the perimysia, a central wide layer of longitudinal collagen fibres and peripheral narrow band of transverse fibres were distinguished. Collagen baskets of adipocytes were observed in the perimysia. 5. Perimysial collagen fibres markedly increased in number and formed a larger fibre cluster during growth from chicks to broilers. Endomysia changed from thin to thicker meshwork with growth. However, the collagen architecture of the muscle in broilers did not change under different nutritional regimes. 6. In conclusion, ITL muscle of chicken develops optimally when body growth is enhanced, but the collagen content and architecture in broilers are not affected by different growth processes.

Abstract
Magnetic compression anastomosis involves the use of two magnets that are attracted transmurally between two internal organs resulting in compression and subsequent fistula formation (1). We report on the clinical use of magnetic compression anastomosis using extracorporeal magnetic guidance for the treatment of complete obstruction of the common bile duct (CBD) following living donor liver transplantation. This novel treatment has the advantages of low invasiveness and simplicity, and it should be considered as a feasible alternative therapy for biliary obstruction.

Abstract
Living donor liver transplantation (LDLT) offers timely transplantation for patients with hepatocellular carcinoma (HCC). If ABO-incompatible LDLT is feasible, the need for pretransplantation treatment may be eliminated, which may reduce overall morbidity. In this article, we have described 8 adult HCC patients who successfully underwent LDLT from ABO-incompatible donors. Antirejection therapy included multiple preoperative plasmaphereses, splenectomy, and an immunosuppressive regimen with tacrolimus, methylprednisolone, and mycophenolate mofetil. The maintenance dose of immunosuppression did not differ from that of the ABO-identical cases. In addition, we also performed intrahepatic arterial infusion of prostaglandin E1. In 5 patients, we administered a single dose of rituximab, a chimeric CD20 monoclonal antibody. As a result of this treatment, 6/8 patients are still alive. Our experience has shown that it is possible to control antibody-mediated humoral rejection and other complications in adult ABO-incompatible LDLT.

Abstract
BACKGROUND We previously reported a mouse model of bronchial asthma showing eosinophilic inflammation, but not airway hyperresponsiveness (AHR), after prolonged antigen exposure. This model showed an increase of IL-12 in the lung. OBJECTIVE The aim of this study was to investigate the role of IL-12p40 in a murine asthma model with prolonged antigen exposures. METHODS An ovalbumin (OVA)-induced asthma model was first established in wild-type (WT) and IL-12p40-deficient (IL-12p40(-/-)) mice. Both strains of mice were further exposed to either OVA (prolonged exposure group) or phosphate-buffered saline (positive control group) 3 days per week for 3 weeks. During week 4, both groups of mice were given a final challenge with OVA. RESULTS Prolonged antigen exposures resulted in marked suppression of airway eosinophilia in both WT and IL-12p40(-/-) mice. However, AHR persisted in IL-12p40(-/-) but not in WT mice. There were no significant differences of IL-5, IL-13 or IFN-gamma levels in bronchoalveolar lavage fluid between WT and IL-12p40(-/-) mice. The hydroxyproline content of the lung and peribronchial fibrosis were, however, significantly increased in IL-12p40(-/-) mice. CONCLUSION The results suggest that endogenous IL-12p40 is essential for inhibition of AHR and peribronchial fibrosis, but not eosinophilic inflammation, in a murine asthma model with prolonged antigen exposures.

Abstract
BACKGROUND/AIMS Left ventricular hypertrophy (LVH) is prevalent in dialysis patients and is recognized as a potent risk factor for cardiovascular diseases. We examined the evolution of LVH after starting dialysis and the determinants of changes in LV mass. METHODS A cohort of 107 patients who had two or more echocardiograms at yearly intervals after starting hemodialysis was studied. RESULTS At baseline, the mean LV mass index (LVMI) was 145.8 g/m(2) and 73 (68%) patients had LVH. During the mean follow-up period of 34.5 months, LVMI decreased by 3.9 g/m(2). At last follow-up, the mean LVMI was 141.5 g/m(2) and 68 (64%) patients had LVH. For changes in LVMI, a significant correlation was found in changes in systolic blood pressure, LVMI at baseline, changes in serum albumin concentration, and age. The relationship between changes in LVMI and systolic blood pressure was close during the 1st and 2nd intervals, but became weak gradually during the 3rd and 4th intervals. CONCLUSION Many patients had LVH at starting hemodialysis and continued to have LVH thereafter. The most important determinants of LV mass changes were baseline LV mass and systolic blood pressure control, but the grade of reduction decreased gradually with time. These results suggest that active antihypertensive treatment should be started early to regress LVH and prevent cardiovascular diseases.

Abstract
ABO-incompatible liver transplantation is usually contraindicated. The presence in the recipient of preformed anti-A/B antibodies located on endothelial cells raises the risk of antibody-mediated humoral rejection of the graft. We describe four successful cases of steroid withdrawal in adult patients who had living-donor liver transplantation from ABO-incompatible donors. Antirejection therapy included multiple perioperative plasmapheresis, splenectomy, and a triple immunosuppressive regimen with tacrolimus, methylprednisolone (MPSL), and cyclophosphamide or mycophenolate mofetil (MMF). The maintenance dose of immunosuppression did not differ from that of ABO-identical cases. After transplantation, intrahepatic arterial infusion therapy with prostaglandin E1 (PG E1) was used. As a result, all four patients were able to achieve long-term graft survival without steroid use. They all have good liver function and are leading normal lifestyles. Our experience with these four patients suggests the feasibility of controlling humoral rejection and other complications in adult ABO-incompatible living donor liver transplantations with intrahepatic arterial infusion of PGE1, splenectomy, and plasmapheresis with a regular base of immunosuppression protocol to prevent antibody-mediated humoral rejection.

Abstract
1. The histochemical properties and the collagen content and architecture of the iliotibialis lateralis (ITL) and puboischiofemoralis (PIF) muscles were assessed in Red Cornish x New Hampshire cockerels reared on a high nutrient plane for 80 d (H80d), or a low nutrient plane for 80 d (L80d) or 95 d (L95d). 2. Final live weights were 3410 g in H80d, 2810 g in L80d and 3467 g in L95d. Both ITL and PIF muscle weights were lowest in L80d and did not differ between H80d and L95d. 3. ITL muscle was composed of fast-twitch myofibres such as IIA (high reduced nicotinamide adenine dinucleotide dehydrogenase, NADH-DH activity), IIB (low NADH-DH activity) and IIC (intermediate NADH-DH activity). The high percentage of type IIB myofibres in H80d (76.6%) and L95d (76.2%) birds were reflected in low percentages of type IIC myofibres (12.2%) in H80d birds and type IIA myofibres (8.2%) in L95d birds. Percentages of IIA, IIB and IIC myofibres in L80d cockerels were 12.4, 69.8 and 17.6%, respectively. 4. The myofibres in PIF muscle were divided into two basic types, I and IIA, and a transitional form (I-tr) from IIA to I. In the caudal region, all myofibres in H80d and L95d cockerels were type I but in L80d cockerels 15% of myofibres were categorised as type I-tr. In the cranial region, the great majority (52 to 63%) of myofibres were type IIA. Type I myofibres occurred at a higher percentage in H80d (30.5%) than L95d (21.8%) and type I-tr in L95d (15.7%) than H80d (7.3%) and L80d (11.5%). 5. The total amount of collagen was higher in ITL than PIF muscle in every bird group. In both muscles the highest collagen content was in L95d cockerels but the content did not differ between H80d and L80d birds. The thickness of thick and thin perimysia increased with muscle size. The circular collagen fibre in the thick perimysium was larger in ITL (6.1 to 7.0 microm) than PIF (3.7 to 3.8 microm) muscle but did not differ among the bird groups. 6. From these results, it was concluded that feeding on a high nutritional plane promotes growth of the thigh muscles, with accompanying enlargement of the perimysial thickness, no increase in collagen content and various changes of histochemical properties.
