Abstract
Cardio-facio-cutaneous syndrome (CFC) (OMIM 115150) is a congenital disease caused by constitutive activation of the Raf/MEK/ERK signaling cascade. Unlike aspects of morphological anomalies, metabolic functions related to the disease have garnered little attention. We present severe neuroglycopenic symptoms due to nonketotic hypoglycemia in two children with CFC (Case 1, a 4-year-old male with c.389A > G heterozygous variant in MAP2K1; Case 2, a 3-year-old male with c.770A > G heterozygous variant in BRAF). Case 1 exhibited a nonketotic hypoglycemic coma and clustered left-hemispheric convulsions despite receiving infusion therapy, leading to severe sequelae with choreoathetosis. Brain magnetic resonance imaging of Case 1 showed T2-elongation with restricted diffusion on the bilateral basal ganglia and thalamus, with the dominance of the right putamen. Case 2 presented a prolonged generalized seizure as an initial clinical symptom but fully recovered. The presence of growth hormone and cortisol deficiency was ruled out in both cases. Blood spots acylcarnitine profiles excluded the co-occurrence of mitochondrial HMG-CoA synthase deficiency and HMG-CoA lyase deficiency. These cases demonstrate the potential vulnerability to nonketotic hypoglycemia, especially during lipid shortages. As children with CFC frequently have difficulties feeding, we suggest great attention should be paid to the potential risk of severe nonketotic hypoglycemia.

Abstract
Panton Valentine Leukocidin (PVL) is one of the many toxins produced by Staphylococcus aureus. In Japan, PVL-positive S. aureus strains are mainly methicillin-resistant S. aureus (MRSA). Data regarding PVL-positive methicillin-sensitive S. aureus (MSSA) are scarce. In this report, we describe a case of severe infection by PVL-positive MSSA. A 12-year-old healthy girl was admitted with high fever and pain in the lower back. Computed tomography revealed a diagnosis of psoitis and multiple venous thromboses. Blood cultures obtained after admission revealed infection with MSSA. Her fever continued despite adequate antibiotic therapy. On the fifth hospitalization day, she developed bladder dysfunction, and an abscess was noted near the third lumbar vertebra. She underwent an emergency operation and recovered. Bacterial analyses revealed that the causative MSSA was a PVL-producing single variant of ST8 (related to USA300clone), of sequence type 2149. PVL is known to cause platelet activation. This case demonstrates the need for detailed analyses of the causative strain of bacteria in cases of S. aureus infection with deep vein thrombosis, even in cases of known MSSA infection.

Abstract
Renal osteodystrophy in hemodialyzed patients with DM-HD shows different features from that in non-DM,HD. Two studies were done. One was a comparison of BMD in 30 non-DM,HD patients and 30 DM-HD patients. The second was a comparison of possible factors affecting calcium metabolism in the higher and lower BMD groups (n = 20/21) in the DM-HD patients. BMD was measured by dual-energy X-ray absorptiometry (DEXA; Hologic QDR 1,000/W) in the third lumbar vertebra (L3), head, pelvis, and whole body. The BMDs of the DM-HD group were lower in these areas and whole body than that in the non-DM,HD group. A significant difference was found in the head BMD (p less than 0.05). In the second study, factors which may contribute to the differences in BMD were compared in the DM-HD patients divided into higher and lower BMD of the head. The group with higher head BMD had a value 110% of the mean value or more. Clinical and biochemical test results (age, the time since the first dialysis, body weight, the degree of obesity, height, serum calcium, serum phosphate, serum aluminum, serum c-PTH level and the dose of 1 alpha-OH-D3) were compared. The degree of obesity of the patients with higher BMD was significantly larger than that with lower BMD (p less than 0.005).

Abstract
OBJECTIVE The objective of this paper is to identify predictors for the response to treatment of acute lupus hemophagocytic syndrome (ALHS). METHODS We reviewed seven cases with ALHS admitted to our hospital and published ALHS cases identified in the 2001-2014 Medline database, and then conducted univariate and multivariate analyses to identify predictors for the response to treatment. RESULTS Review of our cases showed a significant and negative correlation between serum ferritin and anti-DNA antibody (p = 0.0025). All three patients treated with cyclosporine A (CsA) were considered responders despite high serum ferritin and corticosteroid resistance. We also reviewed 93 patients with ALHS identified in 46 articles. Multiple logistic regression analysis identified C-reactive protein (CRP) (OR 0.83, p = 0.042) and hemoglobin (OR 1.53, p = 0.026) measured at diagnosis of ALHS as significant predictors of the response to corticosteroid monotherapy. Moreover, among 32 patients treated with CsA, serum ferritin was significantly higher in CsA responders (12163 ± 16864 µg/l, n = 22) than in non-responders (3456 ± 6267/µg/l, p = 0.020, n = 10). Leukocyte count was significantly lower in the CsA responders (1940.0 ± 972.3/µl) than in the non-responders (3253 ± 2198/µl, p = 0.034). CONCLUSION Low CRP and high hemoglobin can predict a positive response to corticosteroid monotherapy while high serum ferritin and low leukocyte count can predict a positive response to CsA in patients with ALHS and therefore, when corticosteroid monotherapy is not effective in such cases, CsA could be the first choice of an additional immunosuppressive agent.

Abstract
BACKGROUND Severe liver dysfunction caused by acetylsalicylic acid (ASA) is quite rare. The purpose is to describe a patient with severe liver dysfunction due to excessive intake of ASA in a suicide attempt, who was successfully treated with living donor liver transplantation (LDLT). DESCRIPTION OF CASE We report a 20-year-old woman who took 66 g of ASA in a suicide attempt. She was admitted to our hospital and received forced alkaline diuresis. However, her liver and renal functions worsened after admission. On the 6th day after intake of ASA, she was transferred to the intensive care unit, and plasma exchange (PE) and continuous hemodiafiltration were performed. Since her liver function did not recover despite repeated PE, she was transferred to another hospital for LDLT on the 8th day. She underwent LDLT with a portion of the liver donated from her mother on the 11(th) day. After the operation, her renal dysfunction continued. Her renal parameters gradually improved, and she was discharged on the 44th post-operative day without renal dysfunction. CONCLUSION PE is effective in removing ASA from blood. Liver transplantation is the only effective treatment if liver function does not recover in spite of repeated PE.

Abstract
We report two cases of Klebsiella oxytoca bacteremia. Case 1 was a 56-year-old man who was transferred to our hospital by ambulance due to diarrhea and general fatigue. On arrival, he was clearly conscious. However he was in septic shock. We injected broad spectrum antibacterial agents and started intensive care. Though intensive care included continuous hemodiafiltration (CHDF), he died 22 hours after admission. Case 2 was a 69-year-old man with a history of gastrectomy for gastric cancer. He had been admitted to a previous hospital due to ileus. His ileus tube was removed on the eighth day, and he then developed a fever of 38 ºC on the following day. He went into shock and became unconscious; he was therefore transferred to our hospital. We diagnosed septic shock and disseminated intravascular coagulation (DIC). We injected broad spectrum antibacterial agents, and recombinant thrombomodulin alpha (rTM). Although he was started in intensive care, his hemodynamics were unstable on the day following admission. Extracorporeal membrane oxygenation (ECMO) and intra-aortic balloon pumping (IABP) were started to maintain his hemodynamics. His condition gradually improved, and he was transferred to the previous hospital for rehabilitation on the 28(th) day. ECMO for septic shock in adults is unusual; however ECMO can be introduced even in patients with severe sepsis under careful monitoring. The new anti-DIC agent rTM is useful for safe driving of ECMO in patients with DIC.

Abstract
BACKGROUND Hepatocellular carcinoma (HCC) ranks as the third leading cause of cancer deaths worldwide. While sorafenib, a multikinase inhibitor targeting the Raf/extracellular signal-regulated protein kinase (ERK) pathway, has been shown recently to provide a survival advantage to patients with advanced HCC, a predictive biomarker has not been developed. We studied whether c-Jun N-terminal kinase (JNK), which promotes liver carcinogenesis in mice, affects therapeutic response to sorafenib in HCC patients. METHODS We collected pathological specimens from 39 patients with advanced HCC before starting sorafenib treatment, and measured JNK activity in HCCs. RESULTS In patients treated with sorafenib, the expression of phospho-c-Jun in HCC, as a read out of JNK activity, was significantly higher (P<0.001) in the non-responder group than in the responder group. c-Jun N-terminal kinase activation in HCC was associated with a decreased time to progression and a poor overall survival (P=0.0028 and P=0.0008, respectively). CONCLUSION In addition, JNK activity was significantly correlated with CD133 expression level. Correspondingly, high expression level of CD133 was linked to a poor response to sorafenib. Furthermore, D-JNKi, a specific JNK inhibitor, reduced the growth of xenografted CD133(+) cells in athymic mice. In conclusion, JNK activation was positively correlated with CD133 expression level and inversely correlated with the therapeutic response to sorafenib, suggesting that JNK activity may be considered as a new predictive biomarker for response to sorafenib treatment.

Abstract
BACKGROUND Cardiac remodeling after acute myocardial infarction is regulated by components of the extracellular matrix. The 47 kD heat shock protein 47 (HSP47) is a collagen-specific molecular chaperone that plays a major role during procollagen processing and/or secretion. OBJECTIVE The purpose of the study was to determine whether HSP47 inhibition can mitigate ligated left anterior descending (LAD) coronary artery-induced myocardial infarction in rats. METHODS Rats were randomly divided into four experimental groups and subjected to the following treatments: 1) intravenous (IV) administration of saline; 2) ligation of the LAD coronary artery; 3) ligation of the LAD coronary artery + IV administration of HSP47 antisense oligonucleotides; or 4) IV administration of HSP47 antisense oligonucleotides. We investigated cardiac histopathology, performed immunoblot and immunohistochemical analyses, and examined cardiac function. RESULTS Rats with ligated LAD coronary artery experienced upregulation of HSP47 expression, remodeling of the left ventricle, and cardiac dysfunction. In contrast, rats with ligated LAD coronary artery treated with HSP47 antisense oligonucleotides had significantly reduced HSP47 expression, cardiac remodeling, and improved cardiac function. Intravenous (IV) administration of HSP47 antisense oligonucleotides alone had no effect on cardiac morphology. CONCLUSION The data strongly support the idea that changes in the extracellular matrix and its components are important determinants of cardiac remodeling after myocardial infarction.

Abstract
CD109 is a glycosylphosphatidylinositol (GPI)-anchored glycoprotein, whose expression is upregulated in squamous cell carcinomas of the lung, esophagus, uterus and oral cavity. CD109 negatively regulates transforming growth factor (TGF)-beta signaling in keratinocytes by directly modulating receptor activity. In this study, we further characterized CD109 regulation of TGF-beta signaling and cell proliferation. We found that CD109 is produced as a 205 kDa glycoprotein, which is then processed in the Golgi apparatus into 180 kDa and 25 kDa proteins by furin (furinase). 180 kDa CD109 associated with GPI-anchored 25 kDa CD109 on the cell surface and was also secreted into the culture medium. To investigate whether furinase cleavage of CD109 is necessary for its biological activity, we mutated arginine 1273 in the CD109 furinase cleavage motif (amino acid 1270-RRRR-1273) to serine (R1273S). Interestingly, CD109 R1273S neither significantly impaired TGF-beta signaling nor affected TGF-beta-mediated suppression of cell growth, although it was expressed on the cell surface as a 205 kDa protein. Consistent with this finding, the 180 kDa and 25 kDa CD109 complex, but not CD109 R1273S, associated with the type I TGF-beta receptor. These findings indicate that processing of CD109 into 180 kDa and 25 kDa proteins by furin, followed by complex formation with the type I TGF-beta receptor is required for the regulation of TGF-beta signaling in cancer cells and keratinocytes.

Abstract
OBJECTIVE Sivelestat sodium hydrate (sivelestat) is a specific synthetic inhibitor of neutrophil elastase (NE). Various studies suggest that sivelestat treatment reduces inflammation. In this study, we tested the hypothesis that sivelestat acts as an inhibitor of inflammatory mediators and prevents nuclear factor-kB (NF-kB) activation. METHODS In the presence and absence of sivelestat, the mouse macrophage cell line RAW 264.7 was stimulated with lipopolysaccharide (LPS) and the levels of inflammatory mediators (TNF-alpha, IL-6 and high mobility group box 1 (HMGB1)) and nitrite in the cell supernatant were measured, along with inducible nitric oxide synthase (iNOS) expression. RESULTS While LPS administration increased the secretion of inflammatory mediators and nitric oxide (NO), sivelestat decreased the secretion of these mediators. Cell signaling studies demonstrated that sivelestat decreased NF-kB activation by inhibiting IkB phosphorylation. CONCLUSION Sivelestat may inhibit the various inflammatory mediators through NF-kB inhibition.

Abstract
SUMMARY This study evaluated the clinical and angiographic outcome of large aneurysms treated with coil embolization at an acute stage in patients with poor-grade subarachnoid hemorrhage (SAH). Between July 1, 2001 and June 30, 2004, eight consecutive WFNS grade 5 patients with large aneurysms (15~23 mm) were treated with endovascular coil embolization within two days and followed for at least 30 months. There were three middle cerebral and five internal carotid artery aneurysms. No patients were treated by craniotomy and none survived without treatment. Two patients died of primary brain damage or cerebral vasospasm within one month. One patient died of pneumonia at 24 months. Four patients were alive with good recovery or moderate disability at the time of final follow-up (30~66 months). Angiography immediately after the procedure showed complete occlusion in three, neck remnant in four, and body filling in one patient. No complication was seen related to the procedure. Three aneurysms that were initially neck remnant developed body filling due to coil compaction. Two were re-treated with coils at six and 12 months and resulted in neck remnant. One patient refused re-treatment and died of re-bleeding. Endovascular coil embolization can be selected at an acute stage for the treatment of aneurysms in patients with poor-grade SAH without intraparenchymal hematoma even if the aneur-ysm is large. Serial follow up by MRA/angiography is necessary for at least 12 months.

Abstract
BACKGROUND No data for patients with failed back surgery syndrome (FBSS) based on the location of adhesions separated by epiduroscopic adhesiolysis have been reported. METHODS We performed epiduroscopic adhesiolysis on 28 FBSS patients to examine the impact of differences in the locations of the separated regions on the treatment results. We performed fluoroscopic imaging through the sacral hiatus to assess the condition of adhesions in the epidural space during the post-adhesiolysis observation period. RESULTS In patients in whom only the epidural space was separated by adhesiolysis, there was a significant improvement in the Roland-Morris disability questionnaire (RDQ) score until 12 weeks after adhesiolysis, but the score gradually returned to the preoperative value thereafter. Among patients in whom the nerve root responsible for radicular pain was separated, there was a long-term improvement in the RDQ, Oswestry disability index 2.0 (ODI), and Japanese Orthopedic Association Assessment of Treatment (JOA) scores. Among patients in whom both the epidural space and the nerve root responsible for pain were separated, there was a 12 week improvement in the RDQ score and 24 week improvements in the ODI and JOA scores. CONCLUSIONS Progressive epidural imaging after adhesiolysis suggested that pain was caused by re-adhesion around the nerve root. Since re-adhesion of the nerve root required some time, the effect of adhesiolysis was maintained for extended periods in these cases. We suggest that epiduroscopic adhesiolysis is an effective therapy for FBSS patients, and that adhesiolysis of the nerve root may exhibit the long-term (24 weeks) efficacy in patients with pain.

Abstract
BACKGROUND The long-term effect of nutrition on cardiac function remains to be elucidated. One possible link is the newly discovered gastric hormone ghrelin, which has been reported to be cardioprotective. AIM The present study examined whether total enteral nutrition (TEN) and total parenteral nutrition (TPN) differ in their modulation of ghrelin production and their effects on cardiac function after ischemia/reperfusion injury. METHODS Rats received isocaloric parenteral or enteral nutrition through implanted vascular catheters or gastrostomy tubes. TEN was administered in a conventional (TEN-C) or immunonutrition (TEN-I) form. After 7 days, serum ghrelin levels were determined by enzyme-linked immunosorbent assays and myocardial function was assessed using the Langendorff isolated heart technique. RESULTS TEN-I animals had significantly higher plasma ghrelin levels than the other groups. After ischemia/reperfusion injury, left ventricular developed pressure decreased in animals receiving TPN when compared to animals receiving TEN-I. Animals receiving TPN also had significant reductions in their maximal rates of increase and decrease in left ventricular pressure when compared to animals receiving TEN-I (unpaired t test, p < 0.05). CONCLUSION TEN-I increases serum levels of ghrelin, which protects cardiac function after ischemic/reperfusion injury. Because TEN-I more effectively protects cardiac function, we recommend it for long-term nutritional support.

Abstract
OBJECTIVES To examine whether moderate changes in cell culture temperature influence the production of various cytokines and associated mediators of inflammation. METHODS We performed lipopolysaccharide (LPS) stimulation of the murine macrophagic RAW264.7 cell line under hyperthermic (40 degrees C), normothermic (37 degrees C) and hypothermic (34 degrees C) conditions. We then measured the levels of heat shock protein 70 (HSP70), heat shock factor protein (HSF) and nuclear factor-kB (NF-kB) dimers (p50 and p65) in the cells, and the levels of high mobility group box 1 (HMGB1) and the cytokines tumor necrosis factor-alpha (TNF-alpha), interleukin 1beta (IL-1beta) and interleukin 6 (IL-6) in the culture supernatants. RESULTS Levels of HMGB1, IL-1beta, IL-6, and TNF-alpha, as well as NF-kB dimers (p50 and p65), were all reduced following LPS stimulation at 40 degrees C and 34 degrees C compared with those at 37 degrees C. Levels of HSP70 and HSF increased at 40 degrees C and 34 degrees C. CONCLUSIONS The application of moderate hyperthermia and hypothermia after LPS-induced cell activation attenuated the inflammatory response and reduced the likelihood of cell damage. These findings suggest that moderate temperature changes modulate the inflammatory response and could be a useful therapy against sepsis.

Abstract
The type, incidence, and severity of complications of balloon-occluded retrograde transvenous obliteration (B-RTO) for gastric varices should be precisely estimated. Complications were evaluated in 38 patients who had fundic gastric varices and 43 B-RTO procedures during injection of ethanolamine oleate (phase 1), within 4 h after injection (phase 2), 24 h after injection (phase 3), and from 24 h to 10 days after injection (phase 4). Endoscopic evaluation at 8 weeks showed resolution of gastric varices in 35 of 38 patients (92%) and smaller varices in the remaining three (8%). B-RTO caused transient hypertension in 35% of patients, hemoglobinuria in 49%, and fever in 33% during phases 1, 2, and 3, respectively. Pleural effusion, pulmonary infarction, ascites, gastric ulcers with unique appearance, localized mosaic-like change of gastric mucosa, and hemorrhagic portal hypertensive gastropathy were noted in phase 4. There were no fatalities. Lactate dehydrogenase, aspartate aminotransferase, and bilirubin increased on day 1. Each datum was retrieved within 7 days. The severity of lactate dehydrogenase elevation correlated significantly with the volume of infused ethanolamine oleate. Thus, B-RTO is a safe and effective management of fundic varices. However, short-term hemodynamic change after B-RTO may cause gastric mucosal damage. Pulmonary infarction and pleural effusion are potential complications.

Abstract
BACKGROUND Respiratory failure with diaphragmatic fatigability is common in patients suffering sepsis or septic shock. However, the development and progress of diaphragmatic fatigability remains poorly understood, and no method has been established to treat fatigability. In this study, we hypothesize that neutrophil activation contributes to the development of diaphragmatic fatigability. We also sought to investigate whether a phosphodiesterase inhibitor, olprinone, improves diaphragmatic fatigability associated with abdominal sepsis and inhibits an increase in myeloperoxidase activity in diaphragmatic muscle. METHODS Male Wistar rats were randomly assigned to a sham group, coecal legation perforation group (CLP), and a phosphodiesterase inhibitor (PDE) pretreated group. At 16 h after surgical procedure, the left hemidiaphragm was removed for the measurement of diaphragmatic contractility and fatigability. In addition, for the measurement of serial changes in myeloperoxidase activity, the right hemidiaphragm was also removed at 4, 8 or 16 h after the surgical procedure in each group. RESULTS In a septic model involving rats, we observed that diaphragmatic muscles were fatigable and myeloperoxidase activity increased. We also demonstrated that intraperitoneal administration of olprinone improves diaphragmatic fatigability and inhibits an increase in myeloperoxidase activity induced by abdominal sepsis. CONCLUSION Olprinone represents a potential therapy for cases of respiratory failure with diaphragmatic fatigability resulting from inhibition of neutrophil activation.

Abstract
Peripheral T-cell lymphomas (PTCL) account for about 10% of all lymphomas in Western countries, respond poorly to therapy, and have short survival with no sustained remission. Furthermore, the complication of hemophagocytic syndrome (HPS) sometimes makes the prognosis of this disease extremely worse. We report here a case of PTCL with an angiocentric growth pattern complicated with HPS successfully treated by high-dose chemotherapy and autologous peripheral blood stem cell transplantation. Our case suggests this approach is an excellent candidate for the treatment of this disease.

Abstract
We report here an autopsy case of true malignant histiocytosis. The patient was a 67-year-old woman who exhibited fever, wasting, hepatosplenomegaly, and progressive pancytopenia. The bone marrow aspiration disclosed hemophagocytosing cells, which resembled histiocytes. The molecular analysis did not show the clonal gene rearrangement of T-cell receptor or immunoglobulin heavy chain. Although the patient had been started on methylprednisolone pulse therapy and chemotherapy with etoposide, she died from cerebral hemorrhage. The autopsy specimens of spleen and liver showed extensive infiltration of atypical cells, for which histiocytic origin was identified with an immunohistochemical method using monoclonal antibodies against CD11c, CD68, macrophage colony-stimulating factor (M-CSF), M-CSF receptor, lysozyme, antitrypsin and alpha1-antichymotrypsin. Recent investigations have disclosed that in most cases diagnosed as malignant histiocytosis, hemophagocytosis was reactive and not evoked by histiocytic malignancy. True malignant histiocytosis, for which histiocytic origin is confirmed, is extremely rare.

Abstract
BACKGROUND Sequestration of concentrated platelets (P-con) during cardiopulmonary bypass (CPB) has been performed to preserve platelet function after cardiac surgery. Since P-con also harvests leukocytes simultaneously, there might be a possibility that the inflammatory effects or ischemia-reperfusion injuries associated with CPB, such as a cardiac or pulmonary dysfunction after cardiac surgery, are reduced with its use. METHODS We retrospectively evaluated 53 patients who underwent cardiac surgery after the introduction of the P-con technique at our institute. There were 20 patients in the P-con group and 33 patients in the control group in whom concentrated platelet were not harvested. RESULTS The patients characteristics and preoperative cardiac and pulmonary function did not differ between the two groups. The percentages of platelets and leukocytes sequestrated were 20.2+/-5.4% and 8.5+/-3.9% of the total estimated circulating cell counts, respectively. There were no significant differences in the postoperative dose of dopamine used, cardiac index, pulmonary capillary wedge pressure or intubation period between the two groups. However, the stroke volume index (p=0.005), left ventricular stroke work index (p=0.002), and ratio of the arterial oxygen tension to the inspired fraction of oxygen on extubation (p=0.02) were significantly greater in the P-con group as compared with those in the control. CONCLUSIONS P-con improved cardiac and pulmonary function after CPB. Simultaneous sequestration of platelets and leukocytes by P-con during CPB may contribute to the improvement of cardiac and pulmonary function after cardiac surgery.

Abstract
The present study was planned to evaluate a role of nitric oxide (NO) in the regulation of regular ruminal contractions in conscious sheep. Intravenous infusion of S-nitroso-acetyl-DL-penicillamine (SNAP) at doses of 3-30 nmol kg(-1) min(-1)for 30 minutes inhibited both the amplitude and frequency of ruminal contractions in a dose-dependent manner. However, intravenous infusion of Nomega-nitro-L-arginine-methyl ester (L-NAME) at doses of 0.3-3.0 micromol kg(-1) min(-1)did not alter the basal tone of intraruminal pressure and the amplitude of ruminal contractions. The frequency of contractions was slightly inhibited by L-NAME infusion at 1.0 micromol kg(-1)min(-1). The effects of L-NAME were abolished by simultaneous infusion of L -arginine at 30 micromol kg(-1) min(-1). These results suggest that exogenous NO can diminish the ruminal contractions, while endogenous NO is not involved in the regulatory mechanism of basal tone and regular phasic contractions of the rumen in healthy sheep.

Abstract
Effects of light and darkness on cell-cycle progression were studied in the log-linear photoautotrophic growth mode of Euglena gracilis. We found that there are light-dependent restriction points in the post-G1 phases, quite in contrast to Chlamydomonas, where a light-dependent restriction is known to exist only in the G1 phase. Thus, in E. gracilis, there are photoinduced commitments of G1-, S- and G2-phase cells that allow them to progress to the G1, S and G2 phases in darkness, and there are dark-induced G1-, S- and G2-phase arrests. In darkness, only committed cells were able to progress to the committed phases (G1, S or G2), whereas uncommitted cells were unable to undergo a cell-cycle transition. Whether or not cells were induced to commit by irradiation, they were eventually arrested somewhere in the G1, S or G2 (but not M) phase within 14 h of being transferred to darkness. We also describe the dependence of photoinduced commitment on light intensity and discuss the results as they relate to cell-cycle progression in continuous light.

Abstract
A comparison of the persistence of mycoplasmas in animals was carried out. When inoculated into liquid media, strains of Mycoplasma bovis, M. arginini, Acholeplasma laidlawii, and A. axanthum persisted for 59-185 days post-inoculation. The survival periods were not significantly influenced by temperature (4, 30, 37 degrees C, and room temperature). The survival periods for M. bovigenitalium, M. gallisepticum, M. bovirhinis, and M. gateae ranged from <7 to 185 days depending on medium components and temperature. Further, it was determined that strains of M. bovigenitalium, M. bovis, M. bovirhinis, M. arginini, and A. laidlawii persisted in a dry paper disc for at most 28, 126, 154, 56 and over >168 days at 4 degrees C, respectively. At 4 degrees C, strains of M. gallisepticum, M. columborale, M. edwardii, M. felis, and M. gateae survived for at most 28, 21, 42, 28, 28 and 70 days, respectively. At 30 degrees C, strains of M. bovis, M. bovirhinis, M. arginini, A. laidlawii, and M. gallisepticum persisted for at most 28, 84, 56, >168 and 14 days, respectively, but strains of M. gallisepticum, M. columborale, M. edwardii, M. felis, M. gateae, and U. diversum did not survive for more than 14 days. In an outdoor environment, strains of M. bovirhinis and A. laidlawii survived for at most 28 and 14 days, respectively. Finally, it was found that 14 isolates of M. gallisepticum persisted for periods similar to those of the reference strains. The results under dry conditions at a variety of temperatures presented contribute to understanding the epizootiology of mycoplasmal infections in the field.

Abstract
We investigated tyrosine phosphorylation of proteins in primary human leukemic cells stimulated by macrophage colony-stimulating factor (M-CSF) in 60 patients with acute myeloid leukemia (AML) and 5 patients with chronic myelomonocytic leukemia and compared the findings for leukemic cells with those of normal human monocytes and bone marrow immature hematopoietic cells. M-CSF induced tyrosine phosphorylation of p140-200, p110, p60, p44, and p42 frequently, and that of p95 and p55 less frequently, in primary myeloid leukemic cells, whereas M-CSF-induced phosphorylation of proteins was not detected in the normal human hematopoietic cells tested. Of these phosphoproteins, p140-200 was phosphorylated in all patients who responded to M-CSF and was considered to be almost identical to Fms, a product of the c-fms proto-oncogene. M-CSF-induced tyrosine phosphorylation was observed frequently (89%) in AML of French-American-British class M4 and infrequently in all other subtypes of AML, including M5. In chronic myelomonocytic leukemia, M-CSF-induced protein phosphorylation was prominent in blast crisis but was not detected in the chronic phase. Both bone marrow immature cells and mature monocytes showed low responsiveness to M-CSF. These findings for responsiveness to M-CSF were correlated with the amount of Fms in each type of cell. We also identified tyrosine phosphorylation of Vav, Shc, and extracellular signal-regulated kinase by M-CSF in some cases. These findings clarified an M-CSF-specific pattern of protein tyrosine phosphorylation and the responsiveness to M-CSF of primary human myeloid cells. Particularly, enhanced phosphorylation responses to M-CSF and increased amounts of Fms protein were observed in restricted human hematopoietic cells with a premature myelomonocytic character.

Abstract
We examined functional, metabolic, and histological changes in the aortic tissue of rats after the period of warm ischemia ranging from 0 to 24 hours to determine the window of time in which grafts can be optimally viable for harvest. Sixty aortas from Brown Norway rats obtained after warm ischemia were used and changes in contraction, endothelial-dependent or -independent vasodilatation, cell viability, and histology were examined. Maximal contraction induced by norepinephrine and potassium chloride decreased time-dependently after exposure to warm ischemia. The warm ischemic period when 50% of the maximal contractile response of freshly isolated arteries was preserved, ranged from 6 to 8 hours. Maximal endothelium-dependent relaxation induced by acetylcholine decreased along with the time of warm ischemia. Endothelium-independent relaxation induced by sodium nitroprusside and forskolin was unaltered for up to 9 hours. Cell viability gradually decreased, and a significant negative correlation was found between warm ischemic period (T: hours) and cell viability (V: %) (V=101.9-2.35T; r(2)=0.96; p<0.0001). Cell viability was greater than 70% within 12 hours postmortem. Histologically, after 9-hour-warm ischemia irreversible changes were detected. Results suggest that the period of warm ischemia for up to 6 hours would be acceptable for preservation of tissue viability.

Abstract
We reported a case of successful simultaneous mitral and aortic valvuloplasty using rasping procedure. A 55-year-old woman with combined valvular disease received this operation. Postoperatively, the mitral valve area increased from 1.15 cm2 to 2.03 cm2. Mitral regurgitation improved. Aortic valve pressure gradient decreased from 21 mmHg to 0 mmHg. Aortic regurgitation also improved. Cardiac Index (CI) increased from 1.94 l/min./m2 to 2.59 l/min./m2. Ejection fraction (EF) also increased from 60% to 82%. The postoperative course was uneventful. Excellent postoperative results of this procedure may be expected, not only in single valvular disease but also in combined valvular disease.

Abstract
The authors report a case of a 70-year-old man, with repeating episodes of systemic subdermal hematoma due to consumption coagulopathy associated with abdominal aortic aneurysm and the bilateral femoral arterial aneurysms. Prior to the first operation for abdominal aortic repair, anticoagulation therapy was applied to treat thrombocytopenia and hypofibrinogenemia. Five years following the first surgery, the same treatment was required before resection of the femoral lesions. Consumption coagulopathy is seen in approximately 1-4% population of aortic aneurysms, however, repeated appearance of symptomatic coagulopathy is rarely reported. Anticoagulation therapy was effective to normalize the coagulation and fibrinolytic system and followed by uneventful surgical resection of the aneurysms.

Abstract
Neutropenic enteritis is a septic or inflammatory disease of the colon. It is usually encountered in patients with hematological malignancy who have undergone chemotherapy, and it presents as fever, diarrhea, and abdominal pain, although the symptoms are not always specific. The diagnostic features of neutropenic enteritis revealed by barium enema, CT and ultrasonography have been reported previously. Here we report 4 cases of neutropenic enteritis in which ultrasound was used for diagnosis, and also for monitoring the clinical course of the disease. Because neutropenic enteritis is rapidly progressive, early diagnosis and therapeutic intervention are required. We believe that ultrasonography is a useful method for examining patients with neutropenic enteritis, being noninvasive, mobile, and providing rapid results in real time, thus aiding early diagnosis and clinical follow-up.
