Abstract
We report a case of hemoperitoneum after percutaneous radiofrequency ablation in a patient with hepatocellular carcinoma. A 60-year-old female was hospitalized for the treatment of thrombasthenia and cirrhosis caused by chronic Hepatitis C, and computed tomography revealed hepatocellular carcinoma, which was treated by percutaneous radiofrequency ablation. After the ablation, hemoperitoneum was suspected because of the low hemoglobin level with abdominal pain. Approximately 6 h after the ablation treatment, the patient suddenly fell into a shock state and died. In this case, medical treatment-related death including malpractice was suspected, and forensic autopsy was performed. The abdominal cavity contained 910 mL of dark red fluid blood and 210 g of soft hemocoagula. Moreover, several puncture marks were observed on the liver surface and diaphragm, and there was no clear damage to the main arteries and veins. Considering the macroscopic and microscopic findings, the cause of death was assumed as hemorrhagic shock due to the hemoperitoneum caused by the damage to the liver by radiofrequency ablation. It is important to consider all the indications and adverse effects of radiofrequency ablation.

Abstract
When exposed to oxidative and electrophilic stress, a protective antioxidant response is initiated by nuclear factor erythroid 2-related factor 2 (Nrf2). However, the extent of its importance in the forensic diagnosis of acute ischemic heart diseases (AIHD), such as myocardial infarction (MI), remains uncertain. On the other hand, immunohistochemical analyses of fibronectin (FN) and the terminal complement complex (C5b-9) prove valuable in identifying myocardial ischemia that precedes necrosis during the postmortem diagnosis of sudden cardiac death (SCD). In this study, we investigated the immunohistochemical levels of Nrf2, FN, and C5b-9 in human cardiac samples to explore their forensic relevance for the identification of acute cardiac ischemia. Heart samples were obtained from 25 AIHD cases and 39 non-AIHD cases as controls. Nrf2 was localized in the nuclei of cardiomyocytes, while FN and C5b-9 were detected in the myocardial cytoplasm. The number of intranuclear Nrf2 positive signals in cardiomyocytes increased in AIHD cases compared to control cases. Additionally, the grading of positive portions of cardiac FN and C5b-9 in the myocardium was also significantly enhanced in AIHD, compared to controls. Collectively, these results indicate that the immunohistochemical investigation of Nrf2 combined with FN, and/or C5b-9 holds the potential for identifying early-stage myocardial ischemic lesions in cases of SCD.

Abstract
Heat shock proteins (HSPs) are molecular chaperones whose primary function is cytoprotection, supporting cell survival under (sub) lethal conditions. They have been implicated in various diseases such as inflammatory diseases and cancer due to their cytoprotective and immunomodulatory effects, and their biological mechanisms have been studied. Central family members include, HSP27, which is induced by various stimuli such as heat shock, hypoxia, hyperoxia, ultraviolet exposure, and nutritional deficiency, and HSP70, which is homeostatically expressed in many organs such as the gastrointestinal tract and has anti-cell death and anti-inflammatory effects. In this study, HSP27 and HSP70 were investigated during thrombus formation and dissolution in a deep vein thrombosis model by immunohistochemistry to determine their involvement in this process and whether their expression could be used as a forensic marker. In the process of thrombus formation and lysis, HSP27 and HSP70 were found to be expressed by immunohistochemical analysis. The role of inhibitors of HSP27 and HSP70 in the pathogenesis of thrombosis in mice was also investigated. When HSP27 or HSP70 inhibitors were administered, thrombi were significantly smaller than in the control group on day 5 after inferior vena cava ligation, indicating pro-thrombotic effects HSP27 and HSP70. If HSP27- or HSP70-positive cells were clearly visible and easily identifiable in the thrombus sections, the thrombus was presumed to be more than 10 days old. Thus, the detection of intrathrombotic HSP27 and HSP70 could forensically provide useful information for the estimation of thrombus ages. Collectively, our study implied that both HSP27 and HSP70 might be molecular targets for thrombus therapy and that the detection of HSP-related molecules such as HSP27 and HSP70 could be useful for the determination of thrombus ages.

Abstract
Here, we report a case of necrotizing fasciitis following intra-articular injection of hyaluronic acid. A 73-year-old female received intra-articular injections of hyaluronic acid due to arthralgia at the left shoulder and knee, and was found dead in her living room at one day. At the forensic autopsy, injection marks with bullae and erythema were found at the left shoulder and knee and liquefactive necrosis of muscle tissues was observed in the left but not right extremities. Histopathological examinations of the left upper arm and thigh revealed severe rhabdomyolysis with lots of bacterial clusters. Bacteriological examinations detected group A Streptococcus from intracardiac blood and affected muscle tissues. Postmortem biochemical analysis of blood showed escalated blood urea nitrogen (133.8 mg/dL), creatinine (4.57 mg/dL) and C-reactive protein (45.0 mg/dL). The cause of her death was diagnosed as streptococcal toxic shock syndrome (STSS). Moreover, it was suggested that the injection was inappropriately conducted and served as a portal of bacterial entry.

Abstract
Heme oxygenase-1 (HO-1), an inducible stress-response protein, exerts anti-oxidant and anti-apoptotic effects. However, its significance in forensic diagnosis of acute ischemic heart diseases (AIHD) such as myocardial infarction (MI) is still unknown. We examined the immunohistochemical expression of HO-1 in the heart samples to discuss their forensic significance to determine acute cardiac ischemia. The heart samples were obtained from 23 AIHD cases and 33 non-AIHD cases as controls. HO-1 positive signals in cardiomyocyte nuclear were detected in 78.2% of AIHD cases, however, that were detected in only 24.2% control cases with statistical difference between AIHD and non-AIHD groups. In contrast to HO-1 protein expression, there was no significant difference in the appearance of myoglobin pallor regions and leukocyte infiltration in the hearts between AIHD and non-AIHD groups. From the viewpoints of forensic pathology, intracardiac HO-1 expression would be considered a valuable marker to diagnose AIHD as the cause of death.

Abstract
Aquaporins (AQPs) are membrane-bound proteins for water transportation and are useful for diagnosing drowning and wound vitality in forensic pathology. Here, we examined intrathrombotic expression of AQP-1 and AQP-3 using deep vein thrombosis models in mice. To perform immunohistochemical analyses, we used anti-AQP-1 and anti-AQP-3 antibodies. In thrombus samples with the post-ligation intervals of 1 to 5 days, AQP-1+ areas were over 70%. At 7 days after the IVC ligation, AQP-1+ areas became less than 50%, eventually decreasing to 11% at 21 days. At 3 days after the IVC ligation, AQP-3+ cells started to appear from the peripheral area. Thereafter, the positive cell number progressively increased and reached to a peak at 10 days after the IVC ligation. When the intrathrombotic AQP-1+ area was as large as the intrathrombotic collagen area or smaller, it would indicate a thrombus age of ≥ 10 days. AQP-3+ cell number of > 30 would indicate a thrombus age of 10–14 days. Collectively, our study implied that the detection of AQP-1 and AQP-3 would be useful for the determination of thrombus age.

Abstract
Abstract
Introduction
Patients with heart failure are reported to have activated platelets leading to thrombotic events. Consequently, immature giant platelets are produced, and platelet distribution width (PDW) and mean platelet volume (MPV) increase. These platelet indices are easily, reasonably, and safely available by routine blood test and recently have been proposed as potential markers of cardiac events. However, little is known about the usefulness of platelet indices in patients with congenital heart disease (CHD).
Purpose
To test whether the hypothesis that PDW and MPV correlate to the severity of heart failure and have prognostic value in both future heart failure-related admission and thrombosis formation in patients with CHD.
Methods
We performed a retrospective, single-centre study that included 400 patients with CHD (median age, 34 years [range: 12–76]; 49% males; 35% single ventricular morphology), who were admitted in our institute between April 2014 and June 2017. We reviewed patients' medical records to assess their clinical information including medical history, blood sample data, and echocardiologic parameters. At first, we assessed the correlation between platelet indices and patients' clinical parameters. Next, we compared platelet indices before and after treatment for heart failure. Finally, using logistic regression and Kaplan-Meier analyses, we assessed prognostic factors of future heart failure-related admission and thrombosis formation.
Results
In multivariate analysis, a significant correlation was found between PDW and logBNP (brain natriuretic peptide) (p<0.001), haemoglobin (p=0.01), D-dimer (p=0.019), Fontan operation (p<0.001) and male sex (p<0.001); as well as between MPV and logBNP (p<0.001), D-dimer (p<0.001) and Fontan operation (p=0.002). Throughout treatment of heart failure, significant reduction was found both in PDW (average value before treatment = 14.2, after treatment = 13.2, p=0.002) and MPV (before = 11.2, after = 10.8, p=0.004). In multivariate logistic regression analysis, predictors of future heart failure-related admissions were PDW (hazard ratio [HR]: 1.365; 95% confidence interval [CI]: 1.005–1.768), MPV (HR: 1.472; 95% CI: 1.055–2.052), age (HR: 1.063; 95% CI: 1.010–1.119), and SpO2 under 85% (HR: 5.089; 95% CI: 1.350–19.18). Using the same analysis, predictors of thrombotic formation were PDW (HR: 1.998; 95% CI: 1.461–2.630), MPV (HR: 1.792; 95% CI: 1.155–2.781), logBNP (HR: 1.196, 95% CI: 1.085–1.320), D-dimer (HR: 1.024; 95% CI: 1.007–1.042) and male sex (HR: 3.071; 95% CI: 1.079–8.737). In addition, during median follow-up of 28 months, the Kaplan-Meier analysis showed an improvement in both heart failure and thrombosis-free survival in the low PDW, as well as the low MPV group.
Conclusion
Platelet volume indices correlate to severity of heart failure and have prognostic value for both cardiac and thrombotic events in patients with congenital heart disease.

Abstract
We report a suicide case of complete decapitation using a self-constructed guillotine. A 45-year-old man, whose body was severely burned, was found dead. The head was completely separated from the middle level of the neck, and a sharp blade with a steel frame was placed between the head and neck. The severance plane passed between the C4 and C5 vertebrae. Vital reactions such as hemorrhage could not be confirmed at the decapitated skin edge because the body was severely burned. Both common carotid arteries were sharply transected. Subendocardial hemorrhage was detected in the left ventricle. Only a little blood, but no soot, was detected in the respiratory tract, including the trachea and bilateral bronchi. Subarachnoid hemorrhage was noted at the edge of the cervical spinal cord. The saturation level of CO-Hb was 5.7% in the left cardiac blood, 5.9% in the right cardiac blood, and 5.8% in the peripheral blood from the femoral vein. Cervical transection was diagnosed as the cause of death. We believe that he was unintentionally burned by spread fire from an automobile after decapitation by a self-constructed guillotine.

Abstract
Dendritic cells (DCs) can essentially contribute to innate and adaptive immune system in various organs. A double-color immunofluorescence analysis was carried out with anti-CD11c and -HLA-DRα antibodies to detect DCs in 53 skin wounds (their postinfliction intervals: group I, 0-3 days; group II, 4-7 days; group III, 9-14 days; and group IV, 17-21 days). CD11c+HLA-DRα+ DCs were first observed in skin wounds with postinfliction intervals of 3 days, and the DC numbers were found to be elevated in skin wounds with the subsequent increase in postinfliction intervals. Semi-quantitative morphometric analyses showed that the DC number was the highest in the 12-day-old wound. More than 50 DCs were present in 8 of 10 samples (80%) in group II and 14 of 16 samples (87.5%) in group III, and there was no difference between the two groups. Thus, the presence of DCs in a skin wound was possibly estimated as postinfliction intervals of at least 3 days. Furthermore, when a skin wound contained > 50 DCs, its age would be judged as 4-14 days. Collectively, the appearance of DCs in human skin wounds may provide useful information in determining the age of a wound.

Abstract
OBJECTIVE Cholesterol crystals (CCs) are frequently found at the site of acute myocardial infarctions (AMIs), but the role of CCs in the onset of AMI remains unclear due to the lack of validated in vivo imaging tools. The aim of this study was to validate the ability of optical coherence tomography (OCT) to detect CCs and to compare the prevalence and distribution of CCs in patients with AMIs and stable angina pectoris. Approach and Results: CC assessment using OCT were compared with histopathology results in 45 coronary samples. We investigated 152 consecutive patients with AMIs and 41 patients with single vessel-diseased stable angina pectoris. Based on the presence of plaque ruptures (PR), AMI patients were divided into 2 groups: those with PR (n=112) and those without PR (n=40). CCs invading fibrous caps were defined as superficial-type CCs. A multivariable logistic regression analysis was performed to determine PR predictors. The sensitivity and specificity of OCT for detecting CCs were 68% and 92%, respectively. The prevalence of plaques with CCs was higher in the AMI with PR group (AMI with PR 81%, AMI without PR 48%, stable angina pectoris 39%, P<0.01). A multivariable logistic model showed that superficial-type CCs and thin-cap fibroatheromas were positive predictors for PR. CONCLUSIONS OCT has a high specificity and modest sensitivity for the detection of CCs. The combination of CCs invading fibrous cap and thin-cap fibroatheromas detected by OCT may better identify rupture-prone plaques.

Abstract
Abstract
Background
There are limited data regarding cardiac resynchronization therapy (CRT) in adult congenital heart disease (ACHD).
Purpose
We aimed to assess early and late outcomes of CRT amongst patients with ACHD.
Methods
We retrospectively studied ACHD patients receiving CRT (2004–2017). Clinical and echocardiographic data were analyzed at baseline, early (1.8±0.8 years) and late (4.7±0.8 years) follow-up after CRT.
Results
Fifty-four ACHD patients (median age 46 years, range 18–73 years, 74% male) had CRT (biventricular paced >90%) and were followed for 5.7±3.0 years. Thirty-nine (72%) patients had a systemic left ventricle (LV). Underlying cardiac anatomy included left ventricular outflow tract lesions (n=17; 32%), tetralogy of Fallot (n=11; 20%), right ventricular outflow tract lesions (n=5; 9%), atrioventricular septal defects (n=5; 9%) and atrial septal defect with right aortic arch (n=1; 2%). Fifteen (28%) patients had a systemic right ventricle (RV): 13 (24%) with congenitally corrected transposition of great arteries, and 2 (4%) with transposition of the great arteries after Mustard repair.
Compared to baseline, CRT was associated with significant improvement at early follow-up in NYHA functional class, QRS duration, cardiothoracic ratio, left and right atrial volume index (P<0.05 for all) in the overall population; improvement in NYHA class was sustained at late follow-up. Amongst patients with a systemic LV, there was significant increase in LV ejection fraction and reduction in LV end-systolic volume at early and late follow up (P<0.05 for both). There is trend in improvement of RV fractional area change in the patients with a systemic RV but not met statistical significance (P=0.070). Findings were summarized in Figure 1.
Eleven patients died and 2 had heart transplantation unrelated to systemic ventricular morphology. Thirty-five (65%) patients responded positively to CRT but only baseline QRS duration was a predictor of the positive response.
Conclusion
CRT results in sustained improvement in functional class, systemic LV size and function. QRS duration but not QRS morphology was a predictor of the positive response seen at early follow-up in 2/3 of ACHD patients.

Abstract
Patients with diabetes frequently present with complications such as impaired skin wound healing. Skin wound sites display a markedly enhanced expression of CCL2, a potent macrophage chemoattractant, together with macrophage infiltration during the early inflammatory phase in skin wound healing of healthy individuals, but the association of CCL2 with delayed skin wound healing in patients with diabetes remains elusive. In this study, we showed that, compared with control mice, mice with streptozotocin-induced diabetes displayed impaired healing after excisional skin injury, with decreased neovascularization, CCL2 expression, and macrophage infiltration. Compromised skin wound healing in mice with diabetes was reversed by the administration of topical CCL2 immediately after the injury, as evidenced by normalization of wound closure rates, neovascularization, collagen accumulation, and infiltration of macrophages expressing vascular endothelial growth factor, a potent angiogenic factor, and transforming growth factor-β. CCL2 treatment further increased the accumulation of endothelial progenitor cells at the wound sites of mice with diabetes and eventually accelerated neovascularization. Thus, the topical application of CCL2 can be an effective therapeutic option for the treatment of patients with diabetes with defective wound repair, promoting neovascularization and collagen accumulation at skin wound sites.

Abstract
We herein report an intoxication case caused by the ingestion of the pesticide Ortoran®, which consists of 50% acephate aqueous solution. A man in his 60 s was found dead in his car with a 100-mL bottle containing approximately 50 mL of Ortoran®. In a gas chromatography - mass spectrometry (GC-MS) screening test, acephate and its metabolite methamidophos were qualitatively detected in his stomach contents. The amounts of acephate and methamidophos (μg/g) in the extract of each body fluid or organ tissue were measured using GC-MS and were as follows: 35.8, 2.84 (heart blood); 44.0, 2.26 (peripheral blood); 2,240, 2.79 (urine); 53.1, 8.91 (brain occipital lobe); 43.7, 2.95 (liver); 102.3, 8.02 (right kidney); and 5450, 22.9 (stomach contents). Based on these results and autopsy findings, the cause of death was concluded to be acute fatal intoxication caused by the pesticide containing acephate and its active metabolite, methamidophos. Concentration ratios between acephate and methamidophos in each body fluid and organ tissue showed higher relative concentrations of brain methamidophos to acephate than those of other organ tissues. A high relative concentration of brain methamidophos may contribute to the intoxication of acephate in humans.

Abstract
In forensic practices, it is often difficult to determine wound vitality in compression marks of the neck with naked eyes. AQP1 and AQP3 are the major water channels associated with skin. Thus, we immunohistochemically examined the expression of AQP1 and AQP3 in neck skin samples to discuss their forensic applicability to determination of the wound vitality. Skin samples were obtained from 56 neck compression cases (hanging, 35 cases; strangulation, 21 cases). The intact skin from the same individual was taken as a control. Although AQP1 was immnunostained in dermal capillaries in both the neck compression marks and intact skin samples, there was no significant difference in the magnitude of AQP1 expression between both groups. On the contrary, AQP3-positive signals could be faintly detected in uninjured skin samples, and the positive signals seemed more intense in the keratinocytes in compression regions. Morphometrical analyses revealed that the ratio of AQP3-expressed keratinocytes was significantly enhanced in neck compression regions, compared with control groups. From the viewpoints of forensic pathology, immunohistochemical detection of AQP3 in the neck skin can be considered a valuable marker to diagnose the trace of antemortem compression.

Abstract
Immunohistochemical investigation of aquaporin (AQP)1 and AQP3 was performed in human skin wounds obtained from forensic autopsy cases. A total of 55 human skin wounds of different postinfliction intervals were collected as follows: group I, 0-3 days (n = 16); II, 4-7 days (n = 11); III, 9-14 days (n = 16); and IV, 17-21 days (n = 12). In uninjured skin samples, AQP1 and AQP3 could be slightly detected in dermal vessels and keratinocytes, respectively. The percentage of AQP1+ vessels and the number of AQP3+ keratinocytes were apparently elevated in accordance with wound ages. The number of AQP3+ keratinocytes was distinctly evident in groups II and III. Morphometrically, both AQP1+ vessel area and AQP3+ cell number were markedly increased in group II, compared with other three groups. With regard to forensic safety, AQP1+ vessel area of over 5% would imply wound ages of 4-12 days. Moreover, the positive area of > 15% would suggest wound age of 7-10 days. Especially, most samples of skin wounds aged 5-10 days except for only one sample (a 10-day-old wound) showed AQP3+ cell number of > 300, and the remaining other samples had that of < 300. Thus, the AQP3+ cell number of > 300 would indicate wound ages of 5-10 days. Collectively, immunohistochemical analyses of AQP1 and AQP3 in human skin wounds would support the objective accuracy of wound age determination.

Abstract
Endothelial progenitor cells (EPCs), a newly identified cell type, are bone marrow-derived progenitor cells that co-express stem cell markers and vascular endothelial growth factor (VEGF) receptor (Flk-1). In this study, a double-color immunofluorescence analysis was carried out using anti-CD34 and anti-Flk-1 antibodies to examine the time-dependent appearance of EPCs, using 52 human skin wounds with different wound ages (Group I, 0-1 days; Group II, 2-6 days; Group III, 7-14 days; and Group IV, 17-21 days). In wound specimens with an age of less than one day, CD34(+)/Flk-1(+) EPCs were not detected. EPCs were initially observed in wounds aged two days, and their number was increased in lesions with advances in wound age. In morphometrical analysis, the average number of EPCs was the highest in the wounds of Group III. Especially, 20 out of 21 wounds aged 7-12 days had >20 EPCs, and all wound samples with postinfliction intervals of 14-21 days had <15 EPCs. These observations at least showed that >20 EPCs would indicate a wound age of 7-12 days. Taken together, our observations indicate the detection of EPCs would be useful for wound age determination.

Abstract
BACKGROUND AND METHODS We have noticed the possibility that preoperative spirometry may discover latent COPD patients. When COPD is discovered before operation, we can start to treat COPD promptly. Consequently, the better perioperative care is given to COPD patients. On discharge, patients are referred to their family doctors, so that they can receive COPD treatment. RESULTS There activities were started in July 2012. During the initial twelve months, 90 patients of COPD II x III were discovered and treated before admission. FEV1.0 was significantly improved (1.54 l vs. 1.71 l in average) on repeated spirometry on admission. There was no adverse event in COPD treatment All patients have shown good clinical courses. CONCLUSIONS Latent COPD patients can be discovered by preoperative spirometry.

Abstract
To study the relationship between antibodies detected in patients’ and/or donors’ sera and the clinical features of acute non-haemolytic transfusion reactions (ANHTRs), and to determine any gender-related difference. ANHTRs range from urticaria to transfusion-related acute lung injury (TRALI). Antibodies to human leukocyte antigen (HLA), granulocytes, platelets, and/or plasma proteins are implicated in some of the ANHTRs. A higher antibody positivity is expected for females than for males. A comparative study of ANHTRs for antibody positivity and their clinical features between females and males for both patients and donors is helpful for characterizing ANHTRs including TRALI more clearly, but such studies are few and outdated. Two hundred and twenty-three ANHTR cases reported by 45 hospitals between October 2000 and July 2005 were analysed. The patients and 196 donors of suspect blood products were screened for antibodies to HLA Class I, HLA Class II, granulocytes, and platelets. The patients were also screened for anti-plasma protein antibodies. The types and severity of ANHTR did not differ significantly between female and male patients. The frequency of the anti-HLA antibodies, but not that of the non-HLA antibodies, was significantly higher in females. Non-HLA antibodies were significantly associated with severe reactions in females. All the TRALI cases had predisposing risk factors for acute lung injury, and 60% of the cases showed anti-leucocyte antibodies. Although the anti-HLA antibodies were detected more frequently in females than males, no significant association of ANHTRs including TRALI with gender, not only for patients, but also for donors, could be shown in this study.

Abstract
The purpose of this study was to develop poly(D,L-lactic/glycolic acid) (PLGA) or poly(D,L-lactic acid) (PLA) nanoparticles of less than 200 nm in diameter that encapsulated water-soluble corticosteroid derivatives for sustained release and targeting to inflammatory sites. Nanoparticles were prepared with PLGA (or PLA), zinc, betamethasone phosphate and surfactant by an oil-in-water solvent diffusion method. With this method, the efficiency of encapsulating betamethasone phosphate in the nanoparticles and the particle size were significantly affected by various factors, such as the concentration of PLGA (or PLA) and the amount of zinc added. Nanoparticles ranging from 80 to 250 nm in diameter could be prepared, with a maximum betamethasone phosphate content of 8% (w/w). Betamethasone phosphate was gradually released from the nanoparticles in diluted serum, and the release rate depended on the glycolic/lactic acid ratio and on the molecular weight of PLGA or PLA. Betamethasone was gradually released over at least 8 days from murine macrophages that had internalized betamethasone phosphate-encapsulated nanoparticles in vitro, and the rate of release was slower than from nanoparticles prepared without zinc. These results suggest that zinc increases the efficiency of encapsulating betamethasone phosphate in nanoparticles and also promotes sustained release of betamethasone phosphate from the nanoparticles.

Abstract
The role of APX (ascorbate peroxidase) in protection against oxidative stress was examined using transgenic tobacco plants. The full length cDNA, coding Arabidopsis thaliana L. APX fused downstream to the chloroplast transit sequence from A. thaliana glutathione reductase, was cloned into appropriate binary vector and mobilized into Agrobacterium tumefaciens C58C2. Leaf discs were infected with the Agrobacterium and cultured on medium supplied with kanamycin. The incorporation of the gene in tobacco genome was confirmed by Southern dot blot hybridization. Transgenic lines were generated, and the line Chl-APX5 shown to have 3.8-fold the level of APX activity in the wild-type plants. The isolated chloroplasts from this line showed higher APX activity. During early investigation, this line showed enhanced tolerance to the active oxygen-generating paraquat and sodium sulphite. The first generation of this line, also, showed enhanced tolerance to salt, PEG and water stresses, as determined by net photosynthesis. The present data indicate that overproducing the cytosolic APX in tobacco chloroplasts reduces the toxicity of H(2)O(2).

Abstract
A 71-year-old Japanese male with myelodysplastic syndrome progressing to overt leukaemia and hepatocellular carcinoma developed dyspnea and urticaria immediately after infusion of platelet concentrate (PC). He exhibited an identical reaction following blood transfusion. Serum haptoglobin was undetectable. The patient was determined to be homozygous for Hp(del) by polymerase chain reaction (PCR). Antibody to haptoglobin was detected by enzyme-linked immunosorbent assay (ELISA) and Western blot analysis. No antibodies against human leucocyte antigen (HLA) or platelet-specific antigens were detected. Washed PC and washed red blood cells were effective in preventing the transfusion-related anaphylactoid reactions.

Abstract
A new allele of the human neutrophil antigen (HNA) system (tentatively called NA2M) was discovered and its nucleotide sequence was determined. NA2M differs in a single nucleotide (193G-->A) from FCGR3B*2(NA2), resulting in an amino acid change (54Glu-->Lys). The frequency of the NA2M gene in the Japanese population was estimated to be 0.008. Granulocytes of individuals possessing NA2M reacted with HNA-1b(NA2)-specific monoclonal antibody (TAG2) in the GIFT assay.

Abstract
We present herein a case report of vanishing colon cancer with intussusception. A 70-year-old man with hematochezia was admitted to our hospital. Preoperative images showed ileus due to a colonic tumor. At operation, normograde intussusception without any tumor was recognized at the sigmoid colon. Interestingly, the regional lymph nodes were found to be invaded by tubular adenocarcinoma cells, thus suggesting that the colon cancer existed before the necrosis of the wall took place.

Abstract
Two anhaptoglobinemic patients showing anaphylactic transfusion reactions by antihaptoglobin antibody were found. Southern blot analysis indicated that 2 patients were homozygous for the deleted allele of the haptoglobin gene (Hp(del)) as reported previously. We have identified the junction region of the deletion from genomic DNA of 1 patient using cassette-mediated polymerase chain reaction (PCR). Then, the deleted region from the 5' breakpoint to the promoter region of the Hp was amplified from genomic DNA of a control individual using PCR. DNA sequence analysis of these regions indicated that the 5' breakpoint of the Hp(del) allele was located 5. 2 kilobase (kb) upstream of exon 1 of the Hp and the 3' breakpoint was positioned between 52 and 53 base pair (bp) upstream of exon 5 of the haptoglobin-related gene. There was no significant homology between the DNA sequences flanking the 5' and 3' breakpoints, except for a 2-bp (TG) identity. To examine the gene frequency, we have developed a simple PCR method to detect the gene deletion. We found 8, 16, and 17 Hp(del) alleles in 157 Koreans, 523 Japanese, and in 284 Chinese, respectively, but did not find the Hp(del) in 101 Africans or in 100 European-Africans. The incidence of individuals homozygous for the Hp(del) allele was therefore expected to be 1/4000 in Japanese, 1/1500 in Koreans, and 1/1000 in Chinese. This incidence is higher than that of IgA deficiency in Japanese. More attention should be paid on haptoglobin deficiency and antihaptoglobin antibody as the cause of transfusion-related anaphylactic reactions in Asian populations. (Blood. 2000;95:1138-1143)

Abstract
A 59-year-old man with myelodysplastic syndrome exhibited unticaria, dyspnea, fever, and hypotension immediately after the start of platelet concentrate (PC) transfusion on the 15th day of hospitalization. On the 17th and 21st day of hospitalization, the patient exhibited severe unticaria resembling that of erythroderma after the start of PC transfusion. Anti-IgA IgG antibody was detected by enzyme-linked immunosorbent assay (ELISA) on the 28th day of hospitalization. Anti-IgA (purified from pooled human plasma) was detected by Western blotting. The patient's IgA level was normal. No antibodies against HLA or platelet-specific antigens were detected in serum. The patient had no reaction to administration of washed PC. These findings suggest that anti-IgA antibody might have been responsible for the nonhemolytic transfusion reaction in this patient.

Abstract
We described a case of rheumatoid arthritis (RA) with selective IgA deficiency. A 69 year-old female with RA was admitted because of gall bladder cancer, and also had selective IgA deficiency which serum IgA level was less than 5.0 mg/dl, and IgA 1 and IgA 2 subclasses were not detected. Prior to the operation, she was given red cell compatible blood transfusion because of severe anemia. After 30 min of transfusion, she developed chill, nausea, vomiting and hypotension. These anaphylactic reactions might be induced by the presence of anti-IgA antibody, since the level of this antibody titers in her serum was elevated, assessed by the methods of ELISA and Western blotting. Although a case of RA associated with selective IgA deficiency, and also with elevated serum anti-IgA antibody level is extremely uncommon, attention should be paid to the presence of anti-IgA antibody in patients with selective IgA deficiency to avoid any unexpected anaphylactic reactions.

Abstract
We have previously cloned chondroitin 6-sulfotransferase (C6ST) cDNA from chick embryo chondrocytes. C6ST catalyzes sulfation of chondroitin, keratan sulfate, and sialyl N-acetyllactosamine oligosaccharides. In this study, we report the cloning and characterization of a novel sulfotransferase that catalyzes sulfation of keratan sulfate. This new sulfotransferase cDNA clone was obtained from a human fetal brain library by cross-hybridization with chick C6ST cDNA. The cDNA clone obtained contains a single open reading frame that predicts a type II transmembrane protein composed of 411 amino acid residues. When the cDNA was introduced into a eukaryotic expression vector and transfected in COS-7 cells, keratan sulfate sulfotransferase activity was overexpressed, but C6ST activity was not increased over that of the control. Structural analysis of 35S-labeled glycosaminoglycan, which was formed from keratan sulfate by the reaction with 35S-labeled 3'-phosphoadenosine 5'-phosphosulfate and the recombinant sulfotransferase, showed that keratan sulfate was sulfated at position 6 of Gal residues. On the basis of the acceptor substrate specificity, we propose keratan sulfate Gal-6-sulfotransferase (KSGal6ST) for the name of the newly cloned sulfotransferase. KSGal6ST was assigned to chromosome 11p11. 1-11.2 by fluorescence in situ hybridization. Among various human adult tissues, a 2.8-kilobase message of KSGal6ST was expressed mainly in the brain. When poly(A)+ RNAs from the chick embryo cornea and brain were probed with the human KSGal6ST cDNA in Northern hybridization, a clear band with about 2.8 kilobases was detected. These observations suggest that KSGal6ST may participate in the biosynthesis of keratan sulfate in the brain and cornea.

Abstract
Serum levels of interleukin-1 (IL-1 beta), interleukin-6 (IL-6), interleukin-8 (IL-8), tumor necrosis factor (TNF-alpha), and granulocyte-macrophage colony-stimulating factor (GM-CSF) were measured preoperatively in 24 patients with colorectal cancer. IL-1 beta was not elevated, IL-6 and IL-8 were markedly elevated, and GM-CSF was slightly elevated. TNF-alpha was not detected in most patients. Serum IL-6 levels correlated closely with serum IL-8 levels and with serum carbohydrate antigen (CA) 19-9 levels. Serum IL-6 levels were significantly higher in patients whose tumors exceeding 5.0 cm in diameter or spreading circumferentially. Serum IL-8 levels showed significant differences according to histological type, being lower in well differentiated adenocarcinoma compared to other types. Serum levels of IL-6 and IL-8 were significantly higher in patients with liver metastasis than in those without liver metastasis and serum levels of both these cytokines were also significantly higher in patients with lung metastasis than in those without lung metastasis. These results suggest that IL-6 and IL-8 may play an important role in the hematogenous metastasis of colorectal cancer.

Abstract
The preoperative serum levels of carbohydrate antigen 19-9 (CA 19-9) were determined in 206 patients with colorectal cancer, 52 (25.2%) of whom were found to be positive. All of these patients had advanced cancers and significantly higher incidences of tumor invasion through the muscularis propria (91.3%) and lymph node involvement (54.5%). The incidences of liver metastasis and Dukes' stage D in the CA 19-9-positive group were 38.5% and 42.9%, respectively, significantly higher than those in the CA 19-9-negative group of 6.5% and 14.8%, respectively. Moreover, the incidence of liver metastasis in the CA 19-9-positive group patients with Dukes' stage D cancer was 95.2% (20/21); CA 19-9 showing higher specificity (81.7%) and a more positive predictive value (38.5%) for liver metastasis than the carcinoembryonic antigen (CEA). When a cutoff value of 160 U/ml was used, the specificity and positive predictive value reached 97.7% and 81.0%, respectively. An analysis of response operating characteristic (ROC) curves for liver metastasis revealed that CA 19-9 was more useful than CEA. The long-term survival of the CA 19-9-positive group patients was significantly worse than that of the CA 19-9-negative group patients (P < 0.0001), with no 1.25-year survivors in the former group when the cutoff value of 160 U/ml was used. These results suggest that serum CA 19-9 as a useful preoperative indicator of liver metastasis and prognosis in colorectal cancer.

Abstract
Correlation of c-erbB-2 protein (n = 44), epidermal growth factor receptor (EGFR) (n = 41) expression, and DNA ploidy pattern (n = 42) with clinical outcomes of human colorectal cancers was studied. Using monoclonal antibodies against c-erbB-2 protein and EGFR, an immunohistochemical study of the expression of c-erbB-2 protein and EGFR in frozen tissue sections from the lesion was performed. There was no significant correlation between the expression of c-erbB-2 protein and clinicopathological findings such as, tumor size, histological type, depth of invasion, lymph node metastasis, lymphatic vessel invasion, or venous invasion. However, the incidence of c-erbB-2 protein expression in Dukes D was significantly higher (9/10, 90%) than that in Dukes A to C (16/34, 47.1%). Similar tendency was also observed in the expression of EGFR. Aneuploid case was observed in 12 of observed 25 (48%) cases without lymph node metastasis, while it was observed in 16 of 17 cases (94.1%) with lymph node metastasis and there was significant association between DNA ploidy pattern and lymph node metastasis (P < 0.01) and most of the cases (17/20, 85%) were aneuploidy in Dukes C and D. The results above suggest that the expression of c-erbB-2 protein or EGFR was associated with distant metastasis, while on the other hand DNA ploidy pattern was correlated with lymph node metastasis.

Abstract
The coexpression of EGFR and c-erbB-2 protein was examined immunohistochemically in a total of 62 freshly frozen specimens of colorectal cancer, and correlations between the coexpression of both receptors and their clinicopathological variables were analyzed. Positive staining of both receptors was found in 21 cases, and it was related to the degree of lymphatic or vascular invasion of cancer cell, the synchronous metastasis to liver or lung, and the most advanced stage (Dukes' D). Moreover, the incidence of the distant metastasis including metachronous metastasis to other organs such as liver, lung or peritoneum were significantly higher in the positive cases of both receptors. These results suggest that the coexpression of EGFR and c-erbB-2 protein may be related to the distant metastasis of colorectal cancer.

Abstract
One hundred and thirty cases of gastric carcinoma were immunohistochemically examined in regard to the expression of c-erbB-2 protein. C-erbB-2 protein was expressed in 36 cases. Number of cases in the differentiated type was 31 out of 78 cases, whereas that of the undifferentiated type was 5 out of 52 cases. And there were 2 positive cases among 26 cases of early type, whereas there were 34 positive cases of advanced type. In 60 cases of differentiated and advanced type carcinomas, the positive staining related significantly with tumor size, infiltrative growth pattern and peritoneal dissemination. The 5 year survival rate after curative resection was analyzed among the patients with differentiated type carcinoma. The rate of 39 negative cases was 78.0%, whereas it was 46.4% in 20 positive cases. These results indicate that the expression of c-erbB-2 protein in gastric carcinoma may be related to the degree of differentiation and the stage of progression, and further, it seems well correlated with the biological behavior of the differentiated but advanced carcinoma as shown by the positive tendency in larger size, deeper infiltration and shorter 5 year survival.

Abstract
The present study was undertaken to investigate the role of cholinergic mechanisms in the behavioral effects of RU-24969, a compound with serotonin1B (5-HT1B) receptor agonist properties. RU-24969 caused an increase in locomotion (2-5 mg/kg IP) and an impairment of spontaneous alternation (SA) behavior in a T-maze (0.5-2.0 mg/kg IP) in mice, effects that were also induced by the cholinergic hypofunction with scopolamine treatment (0.5-5.0 mg/kg IP), an acetylcholine (ACh) receptor antagonist. The impairment of the SA behavior by RU-24969 was enhanced by scopolamine. Both the hyperlocomotion and the SA impairment by RU-24969 were markedly reduced by propranolol (20 mg/kg IP) which has 5-HT1A/5-HT1B receptor antagonist properties, as well as by physostigmine (0.05-0.2 mg/kg IP), an ACh esterase inhibitor, and oxotremorine (0.005-0.01 mg/kg IP), an ACh receptor agonist. Moreover, these behavioral deficits of RU-24969 were diminished in mice pretreated intracerebroventricularly with AF64A (30 nmol/body), a presynaptic cholinergic neurotoxin, whereas scopolamine induced the deficits even in animals with the same treatment. These results suggest that the serotonergic behavioral deficits observed after RU-24969 treatment may be caused by an inhibition of ACh release through its action on the presynaptic receptor (particularly RU-24969-sensitive sites) localized on the cholinergic terminals.

Abstract
A 56-year-old male attempted suicide by ingestion of about 60 ml of 50% fenitrothion (Sumithion) emulsion. Five hours later, combined hemoperfusion and hemodialysis (HP-HD) treatment was performed for 60 min and consequently the toxic symptoms improved gradually. However, cholinergic symptoms recurred 4 days after ingestion. Although HP-HD was immediately performed for 180 min, it had no effect on the clinical symptoms. He died of respiratory insufficiency 6 days after the ingestion of fenitrothion. Fenitrothion concentration in the organs and tissues showed the highest values in the fat tissue, followed in decreasing order by the pancreas, muscle, lung and brain. The results indicate that fenitrothion has high lipid solubility and deposits in the fat tissue. Furthermore, we believe that when HP-HD therapy is used in the treatment of acute insecticide poisoning it is important that it be performed continuously and in as early a stage as possible.

Abstract
This report describes a 54-year-old man with hypertrophic cardiomyopathy whose electrocardiogram had developed abnormal changes characterized by progressive ST-segment elevation with Q waves during eighteen years period. The ECG taken on the initial examination at his age of 36 showed a high voltage QRS complex with deep inverted T waves in V3-6. Twelve years later, these inverted T waves became shallow and ST-segment elevation was recognized. Since the age of 49, the ECG showed persistent ST-segment elevation and Q waves in V3-6 mimicking anterolateral myocardial infarction. At the age of 54, he suddenly died of ventricular tachycardia. At necropsy the heart showed the thickened ventricular septum and transmurally infarcted scar in the anteroseptal area near the apex with patent epicardial coronary arteries. Microscopic examination revealed myofibrillar disarray in the ventricular septum and significant intramural coronary artery narrowing in the left ventricular free wall and ventricular septum. The association of myocardial infarction in hypertrophic cardiomyopathy with the patent epicardial coronary artery has been reported by Maron et al, who stressed the role of the narrowing of intramural coronary arteries in such cases. In the present report, we discussed the pathogenesis of myocardial infarction in hypertrophic cardiomyopathy with a review of literature.
