Abstract
Psychosomatic disorders are influenced by psychosocial factors such as interpersonal relationships. Coping behaviors, especially in frustrating situations, reflect a patient's ability to cope with stress, and it is important to assess these behaviors for the treatment of psychosomatic diseases. This study aimed to clarify the interpersonal relationships and coping behaviors of pediatric patients with psychosomatic diseases during frustrating situations simulated using the Rosenzweig Picture-Frustration study. This retrospective study included 126 patients (41 male, 85 female) with an average age of 12.9 (6-16) years who were consulted at the Department of Pediatric Psychosomatic Medicine at Okayama University Hospital from 2013 to 2018 and underwent the P-F study. Each score was compared with a standardization sample. The mean group conformity rating did not differ significantly between the participants and healthy children. Compared with healthy children, those with psychosomatic diseases were less likely to explain their perspective. The children with psychosomatic disorders responded to frustrating situations in a sensible and age-appropriate manner. However, they were less likely to respond by explaining their perspective to protect themselves.

Abstract
BackgroundPatients with SLE are recommended to continue the maintenance therapy with as less glucocorticoid as possible.1) However, tapering glucocorticoid often results in the recurrence of SLE. Current reports suggested that adding BEL to the standard therapy could lead to the reduction of glucocorticoid and the recurrence of SLE.2)ObjectivesThe aim of this study is to evaluate the efficacy and the safety of BEL as co-treatment in the standard therapy of SLE.MethodsFourteen patients receiving the maintenance therapy of SLE were enrolled in this study. Dose of prednisolone (PSL), titer of anti-DNA antibody, WBC count, serum complement and SLE disease activity index (SLEDAI) were examined retrospectively at baseline and 24 months after administration of BEL.ResultsAt the baseline, the mean age of patients was 48 years old, 11 patients were female, and the mean disease duration was 8.6 years. The mean dose of PSL was significantly reduced (meansease apre-administration of BEL:6.1±1.1 mg/day, 24 months after administration of BEL: 1.2 the baseline,p=0.001). Furthermore, six patients (43 %) could withdraw PSL without the flare of the disease. There were also statistical significance about SLEDAI between baseline and after treatment by BEL(2.1patients (43 %) cp=0.03) and the titer of anti-DNA antibody (6.8 withdraw PSL without tp=0.03). There were no statistical significant in WBC count (6177out the fla7e of the dp=0.24) and serum complement (C3 87significant in WBC count (61p=0.78, C4 20erum complement (C3 87signifp=0.54).As for adverse event, bacterial pneumonia (n=1) and pulmonary cryptococcosis (n=1) was revealed.ConclusionOur study is suggested that co-treatment with BEL on standard SLE therapy was enable to prevent the flare of SLE and reduce the dose of PSL with statistical significance among the patients under the maintenance treatment of SLE. In almost half of the cases, patients could withdraw PSL without the flare.References[1]Ann Rheum Dis 2019; 78: 736-745.[2]Ann Rheum Dis 2018; 77: 355-745.Disclosure of InterestsNone declared

Abstract
AIM Social cognition encompasses facial expression recognition (FER), theory of mind, and empathy. Although studies examining FER in large numbers of patients with mild cognitive impairment (MCI) or dementia are rare, relative preservation of happiness recognition in dementia was reported in some studies. In this study, we examined performance on FER tests and its relationship to clinical demographics and other cognitive function test scores in patients with cognitive decline. METHODS The present study administered an FER test and several cognitive tests to outpatients at a memory clinic. The FER test presents four facial expressions (happiness, surprise, anger, and sadness). A total of 187 patients were placed in one of the three groups based on their cognitive status: dementia group (n = 63), MCI group (n = 92), and normal cognition group (n = 32). RESULTS The total scores on the FER test significantly differed among the three groups (normal > MCI > dementia). In the recognition of happiness and surprise, the dementia group had significantly lower scores than the normal cognition group. There were no significant differences in the recognition of anger and sadness scores among the three groups. The FER scores for happiness and surprise were primarily related to executive function scores, but the FER scores for anger and sadness were primarily related to age. CONCLUSIONS We note the difference in recognition of causative factors among the four emotions (happiness, surprise, anger, sadness). Our study raises serious doubts about the preservation of happiness recognition hypothesis in dementia based on FER tests.

Abstract
BACKGROUND Early detection of mild cognitive impairment (MCI) and dementia is important to promptly start appropriate intervention. However, it is difficult to examine a patient using long and thorough cognitive tests in a general clinical setting. In this study, we aimed to investigate the diagnostic validity of the Addenbrooke's Cognitive Examination - III (ACE-III), Mini-ACE (M-ACE), Montreal Cognitive Assessment (MoCA), Hasegawa Dementia Scale-Revised (HDS-R), and Mini-Mental State Examination (MMSE) to identify MCI and dementia. METHODS A total of 249 subjects (controls = 50, MCI = 94, dementia = 105) at a memory clinic participated in this study, and took the ACE-III, M-ACE, MoCA, HDS-R, and MMSE. After all examinations had been carried out, a conference was held, and the clinical diagnoses were established. RESULTS The areas under the curve (AUC) of the ACE-III, M-ACE, MoCA, HDS-R, and MMSE for diagnosing MCI were 0.891, 0.856, 0.831, 0.808, and 0.782. The AUC of the ACE-III was significantly larger than those of the MoCA, HDS-R, and MMSE. The AUCs of the ACE-III, M-ACE, MoCA, HDS-R, and MMSE for diagnosing dementia were 0.930, 0.917, 0.854, 0.871, and 0.856. Thus, the AUCs of the ACE-III and M-ACE were significantly larger than those of the MoCA, HDS-R, and MMSE. CONCLUSION The ACE-III is a useful cognitive instrument to detect MCI. For distinguishing dementia patients from non-dementia patients, the ACE-III and M-ACE are superior to the MoCA, HDS-R, and MMSE.

Abstract
Background Early detection of mild cognitive impairment (MCI) and dementia is very important to begin appropriate treatment promptly and to prevent disease exacerbation. We investigated the screening accuracy of the Japanese version of Addenbrooke’s Cognitive Examination III (ACE-III) to diagnose MCI and dementia. Methods The original ACE-III was translated and adapted to Japanese. It was then administered to a Japanese population. The Hasegawa Dementia Scale-revised (HDS-R) and Mini-mental State Examination (MMSE) were also applied to evaluate cognitive dysfunction. In total, 389 subjects (dementia = 178, MCI = 137, controls = 73) took part in our study. Results The optimal ACE-III cut-off scores to detect MCI and dementia were 88/89 (sensitivity 0.77, specificity 0.92) and 75/76 (sensitivity 0.82, specificity 0.90), respectively. ACE-III was superior to HDS-R and MMSE in the detection of MCI or dementia. The internal consistency, test-retest reliability, and inter-rater reliability of ACE-III were excellent. Conclusions ACE-III is a useful cognitive test to detect MCI and dementia. ACE-III may be widely useful in clinical practice.

Abstract
Overweight/obesity among adult survivors of childhood SCT has been considered to be predictive of eventual development of metabolic abnormalities. Fatty liver is increasingly recognized as a major cause of liver-related morbidity and mortality in the general population. However, the real incidence of fatty liver in adult survivors of SCT has not been fully elucidated. We determined whether adult survivors are at risk for overweight/obesity, metabolic abnormalities and fatty liver and whether these risks are associated with cranial radiotherapy (CRT) before SCT. Among the 51 patients (30 males), only two male patients were overweight/obese at the last evaluation. On the other hand, 9 male (30%) and 15 female (71%) patients were underweight. Fatty liver was diagnosed in 11 male (37%) and 10 female (48%) patients during the follow-up period, although patients who had fatty liver did not tend to be overweight/obese. Significantly more patients who received CRT before SCT developed fatty liver with insulin resistance than those who did not (P<0.05). Even patients who are not overweight/obese may develop fatty liver and metabolic abnormalities. We recommend that healthcare professionals recognize these risks and give life-long attention to detecting, preventing and treating late complications after SCT.

Abstract
An increasing number of long-term surviving bone marrow transplantation (BMT) recipients have recovered from their primary disease but are at risk of developing failure of endocrine organs. We investigated 30 recipients who underwent allogeneic BMT during childhood or adolescence. Testicular growth and function were evaluated by serial measurement of testicular volume, basal luteinizing hormone (LH), basal follicle-stimulating hormone (FSH) and testosterone levels and by gonadotropin-releasing hormone (GnRH) provocative test. Puberty started spontaneously in all patients. However, all except four patients had normal testosterone levels with elevated LH, indicating partial Leydig cell dysfunction. Standard deviation scores of testicular volume at last evaluation were statistically lower in those who had received irradiation without gonadal shield compared to those with (-2.04+/-0.45 vs -0.30+/-1.17, respectively, P<0.005), suggesting damage of testicular germinal epithelium owing to gonadal irradiation. Serial measurement of testicular volume showed a tendency of growth to stop at 10 ml in those without gonadal shield. Among the 30 patients, only one patient has fathered a child after reaching spontaneous puberty. These results suggest that gonadal shield is effective to protect testicular growth and function, although the attainment of fertility is difficult to achieve.

Abstract
The authors report a 14-year-old boy with Wiskott-Aldrich syndrome complicated by progressive multifocal leukoencephalopathy after allogeneic bone marrow transplantation. Several therapeutic approaches were attempted, but there was no response. The patient died 2 months after the onset of neurologic symptoms. We detected three distinct, rearranged regions of JC virus in the cerebellum, occipital lobe, and brainstem. These findings suggest that the brain lesions had three independent origins.

Abstract
To establish the most appropriate prophylactic therapy and risk factors for predicting hemorrhagic cystitis (HC) after stem cell transplantation (SCT), we retrospectively analyzed the clinical records of 450 transplant patients treated from 1982 to 2002. In all, 81 patients developed early- and/or late-onset HC (early=29, late=48, both=4). For the incidence of early-onset HC, administration of cyclophosphamide (CY) (p=0.0079, odds ratio (OD)=5.109, 95% confidence interval (CI)=1.533-17.030), busulfan (BU) (p=0.0015, OD=3.336, 95% CI=1.584-7.027), BU+CY (p=0.0001, OD=4.369, 95% CI=2.055-9.292), antithymocyte globulin (p=0.0009, OD=3.368, 95% CI=1.642-6.911), nonradiation (p=0.0163, OD=2.564, 95% CI=0.181-0.841), 2-mercaptoethane sodium sulfonate (Mesna) (p=0.0001, OD=7.519, 95% CI=2.847-19.858), and bladder irrigation (p=0.0001, OD=4.950, 95% CI=2.328-10.523) were risk factors. By Fisher's exact test, the combination of BU and Mesna was a more significant risk factor (P<0.001) than Mesna alone (p=0.008) compared to the administration of neither agent. By multivariate analysis, prophylactic administration of Mesna (p=0.0105, OD=5.301, 95% CI=1.477-19.026) and bladder irrigation (p=0.0001, OD=9.469, 95% CI=3.872-23.156) were significant risk factors of early-onset HC. We conclude that (i). high-dose BU as well as CY is a cause of HC, (ii). protective bladder irrigation has an opposite effect, and (iii). Mesna possibly has a toxic effect on bladder mucosa.

Abstract
We report herein the case of a 33-year-old woman who presented with palpable abdominal swelling found to be caused by a huge lymphangioma of the pancreas. An abdominal computed tomographic (CT) scan showed a large multilocular cystic mass with water-dense contents, which was derived from the pancreatic head. A pancreaticoduodenectomy (PD) was performed because the tumor had invaded the duodenum. The resected tumor, which was 23 x 12 x 23 cm in size with 21 of serous fluid, was pathologically diagnosed as a cystic lymphangioma. The endothelial cells lining the internal surface of the cystic spaces were immunohistochemically positive for factor VIII-R antigen and CD31. Our review of the literature revealed 45 reports of lymphangioma of the pancreas, including this one, but to the best of our knowledge this is only the fifth case that required a PD. Nevertheless, we recommend that a complete resection be performed to reduce the risk of recurrence.

Abstract
The purified CD34(+) cell fraction has been used for hematopoietic stem cell transplantation since they were demonstrated to have long-term reconstituting ability. Therefore, the potential effects of CD34(-) stem cells on the clinical course have been a major concern in recipients of CD34(+)-selected transplantation. To address this concern, we used an in vitro assay to determine whether transplant recipients have CD34(-)precursor population. Lin(-)CD34(-) cells were isolated from bone marrow cells in 11 transplant recipients including four CD34-selected transplantations, six standard bone marrow transplantations, and one T cell-depleted marrow transplantation. The frequency of the Lin(-)CD34(-) population in four CD34-enriched transplantation recipients was not different from those of normal donors or recipients of other modes of transplantation: 0.96 +/- 1.01% (mean +/- s.d., n = 4), 0.45 +/- 0.16% (n = 6), and 0.66 +/- 0.59% (n = 7), respectively. However, the Lin(-)CD34(-)population obtained from the recipients of CD34-enriched transplantation acquired neither CD34 expression nor colony-forming activity after 7 days of culture, whereas the cells from all the normal individuals and standard BMT recipients were able to differentiate into CD34(+) cells accompanied by the emergence of colony-forming activity.We conclude that recipients of CD34-enriched transplantation appear to have defects in their CD34(-) precursor population. The clinical significance of these defects will be determined in a life-long follow-up of these patients.

Abstract
The nucleotide sequences of the coding region of the nucleocapsid (N) gene of 12 mouse hepatitis virus (MHV) strains recently found in animal facilities in Japan were analyzed. Nucleotide sequencing was performed directly on polymerase chain reaction (PCR) products amplified by reverse transcription (RT) and polymerase chain reaction (RT-PCR) analysis from fecal samples or isolated viruses. Phylogenetic analysis of these MHV strains along with those reported previously indicated that sequence analysis of the N gene was a useful tool for differentiation of MHV strains,although most MHV strains in Japanese facilities were phylogenetically close. Results suggested that interchange of mice infected with MHV among facilities provided opportunities of introduction of MHV into otherwise MHV-free facilities and that the source of MHV infection could be traced by use of nucleotide analysis of the N gene.

Abstract
Hemorrhagic cystitis (HC) is a major cause of morbidity after allogeneic bone marrow transplantation (BMT). Many therapies have been investigated to prevent or treat HC, but effective treatment for HC is still limited. While the efficacy of hyperbaric oxygen therapy has been established for HC due to chemotherapy and/or radiation therapy, its role in HC occurring after allogeneic BMT has yet to be defined. We report two cases of life-threatening late-onset HC after allogeneic BMT in children, which resolved after treatment with hyperbaric oxygen.

Abstract
OBJECTIVE We examined cell subsets with respect to cutaneous graft-vs-host disease by cell sorting selection of subsets of human mononuclear cells and injecting the subsets subcutaneously in a mouse model. MATERIALS AND METHODS Cell suspensions containing cultured human epidermal cells and dermal fibroblasts from a single donor mixed with lymphoid cell subsets positively selected using the FACSVantage cell sorting instrument and/or MACS cell isolation kits from unrelated individuals were injected into immunodeficient mice. This model is known to generate human skin with histologic findings similar to human graft-vs-host disease. RESULTS Donor T-cell subsets CD4(+) and CD8(+) plus either host or donor CD14(+) cells were necessary to cause acute cutaneous graft-vs-host disease. Although graft-vs-host disease can result from recognition of class I antigens expressed on human cutaneous cells by donor peripheral blood mononuclear cells, additional recognition of class II antigens expressed on host mononuclear cells resulted in more severe histologic manifestations. Dendritic cells that differentiated from donor and host monocytes also showed competent accessory cell function in this system. CONCLUSIONS Based on this model, human cutaneous graft-vs-host disease was caused by donor CD4(+) cells and CD8(+) cells activated through recognition of host antigens, including class I and class II antigens presented by either donor or host CD14(+) cells or dendritic cells.

Abstract
Growth hormone (GH) deficiency has been regarded as a principal determinant for growth failure following bone marrow transplantation (BMT). We herein analyzed final height and GH secretion in the patients who received BMT during childhood. The study on final height in 30 patients (23 males; 19 with malignant disease) who underwent BMT before or at the onset of puberty showed the following findings: (1) Final height SD score (SDS) significantly decreased compared to pretreatment height SDS. (2) Patients who underwent BMT before the age of 10 years showed significantly greater reduction in height SDS compared to those who received after the age of 10 years. (3) The type of disease or a difference in preconditioning regimen did not influence the outcome of growth. (4) No patient showed GH deficiency. The study on GH secretion included 71 patients who had been followed for more than 5 years and who underwent insulin tolerance test more than twice following BMT. Thirteen patients experienced poor GH response at least once. Two of these patients had poor GH response repeatedly. In conclusion, children who undergo BMT at younger age have a higher risk of growth failure, and GH deficiency is not a major contributing factor for growth impairment following BMT.

Abstract
We report a case of intra-articular fracture of the knee joint showing three layers within lipohemarthrosis. Sagittal ultrasonography showed three layers (double fluid-fluid level): a superior hyperechoic layer of fat, an intermediate anechoic layer of serum, and an inferior hypoechoic layer of red blood cells. Horizontal computed tomography imaging demonstrated the same three layers. This is the first case of lipohemarthrosis in which three layers of joint effusion were confirmed by both ultrasonography and computed tomography.

Abstract
Fanconi anemia (FA) is an autosomal recessive disease characterized by congenital anomalies, aplastic anemia, and a susceptibility to leukemia. There are at least 8 complementation groups (A through H). Extensive analyses of the FA group C gene FANCC in Western countries revealed that 10% to 15% of FA patients have mutations of this gene. The most common mutation is IVS4 + 4 A to T (IVS4), a splice mutation in intron 4, which has been found only in patients of Ashkenazi Jewish ancestry. When we screened 29 Japanese patients (20 unrelated patients and 4 families) using polymerase chain reaction-single strand conformation polymorphism, we found 8 unrelated patients homozygous for IVS4. This is apparently the first non-Ashkenazi-Jewish population for whom this mutation has been detected. The Ashkenazi Jewish patients homozygous for IVS4 have a severe phenotype, in comparison with other FA patients. Our analyses of Japanese patients indicate no significant difference between IVS4 homozygotes and other patients with regard to severity of a clinical phenotype. Thus, ethnic background may have a significant effect on a clinical phenotype in FA patients carrying the same mutation. (Blood. 2000;95:1493-1498)

Abstract
The membrane (M) proteins of murine coronavirus (MHV) strains have been reported to contain only O-linked oligosaccharides. The predicted O-glycosylation site consisting of four amino acid residues of Ser-Ser-Thr-Thr is located immediately adjacent to the initiator Met and is well conserved among MHV strains investigated so far. We analyzed the nucleotide sequence of a highly virulent strain MHV-2 M-coding region and demonstrated that MHV-2 had a unique amino acid, Asn, at position 2 at the conserved O-glycosylation site. We also demonstrated that this substitution added N-linked glycans to MHV-2 M protein resulting in increment of molecular mass of MHV-2 M protein compared with JHM strain having only O-linked glycans.

Abstract
We have isolated the virus from a fecal pellet in the colon of a BALB/c mouse with X-linked immunodeficiency (xid) housed in a room in which there has recently been an epidemic due to mouse hepatitis virus (MHV) and designated it as the MHV-TY strain. Sequence analysis of the MHV-TY strain was performed on major structural, spike (S), membrane (M) and nucleocapsid (N), proteins directly from PCR products. The comparison of nucleotide sequences of MHV-TY with other strains investigated so far revealed that all three structural proteins of the TY strain had some unique amino acid sequences among MHV strains which can be used as markers of this strain.

Abstract
The ability of mixed epidermal cell-lymphocyte reactions to detect allogeneic reactivities in an in vivo model was investigated by developing an in vivo model of acute graft-versus-host disease (GVHD), using SCID mice with a C.B-17 background in which human skin structures were generated by transplantation of cultured human epidermal cells (HEC) with dermal fibroblasts (HDFC). Suspensions containing cultured HEC and HDFC from a single donor were mixed with autologous peripheral blood mononuclear cells (PBMNC) or with PBMNC from unrelated individuals, and were injected into the flanks of C.B-17-SCID mice. Ten and 21 days after injection, subcutaneous nodules generated in the mice were examined histologically and immunohistochemically. Cystic structures developing after injection of HEC and HDFC without human PBMNC showed normal epidermislike tissue. Human skin generated in SCID mice injected with HEC and HDFC with auto-PBMNC showed no graft-versus-host reaction (GVHR) histologically, whereas those mice injected with PBMNC from siblings that shared an HLA haplotype showed mild GVHR. Human skin in SCID mice injected with HEC and HDFC with histoincompatible unrelated PBMNC showed moderate to severe GVHR. The severity of GVHR paralleled the dose of unrelated PBMNC, and GVHR was prevented by peroral treatment with cyclosporine A. Immunohistochemically, inflammatory cells infiltrating human cutaneous tissue formed in the SCID mice were stained by an anti-human CD45RO antibody that reacts with human T cells but not with murine lymphocytes, and most T cells were stained by an anti-human CD8 antibody recognizing HLA class I antigens. These findings are similar to those in clinical skin graft-versus host disease (GVHD) observed in patients undergoing allogeneic bone marrow transplantation. This experimental system should be useful as an in vivo model of human skin GVHD.

Abstract
In a survey of childhood therapy-related acute myeloid leukemia/myelodysplastic syndrome (t-AML/MDS) in Japan, we found 11p15 translocations in 5 (6%) of 81 children with t-AML/MDS. t(11;17)(p15;q21), t(11;12)(p15;q13), t(7;11)(p15;p15), inv(11)(p15q22), and add(11)(p15) were each found in one patient. Southern blotting and/or RT-PCR analyses revealed rearrangements of the NUP98 gene in tumor samples of all five patients. Rearrangements of DDX10 were detected in t-AML/MDS cells with inv(11), and rearrangements of HOXA9 were detected in t-AML cells with t(7;11). The 17q21 breakpoint of t(11;17) and the 12q13 breakpoint of t(11;12)(p15;q13) coincided with the loci of the HOXB and HOXC gene families, respectively. Therefore, it is reasonable to speculate that one of the HOXB genes and one of the HOXC genes were fused to NUP98 by t(11;17) and t(11;12), respectively, in t-AML/MDS cells. We propose that NUP98 may be a target gene for t-AML/MDS, and that t-AML/MDS with a fusion of NUP98 and HOX or DDX10 genes may be more frequent in children than in patients of other age groups.

Abstract
Interleukin-12 (IL-12) is a crucial cytokine regulating cell-mediated immunity, and may contribute to the development of graft-versus-host disease (GVHD). We investigated serum IL-12 concentrations, interferon gamma (IFN-gamma) production by peripheral blood lymphocytes (PBL) from allogeneic stem cell recipients after IL-12 plus anti-CD3 monoclonal antibody (mAb) stimulation. We also investigated IL-12 production by peripheral macrophages (Mphi) after lipopolysaccharide (LPS) stimulation from allogeneic stem cell recipients and patients receiving donor leukocyte transfusions (DLT) for treatment or prophylaxis of leukemia relapse and Epstein-Barr virus (EBV) lymphoproliferative disease (LPD). PBL from acute GVHD patients produced high IFN-gamma levels after IL-12 plus anti-CD3 mAb stimulation, whereas PBL from patients without acute GVHD produced low levels of IFN-gamma. However, serum IL-12 concentrations were low in both groups. Peripheral Mphi IL-12 production increased in patients who developed acute GVHD compared to patients without acute GVHD. Five patients receiving DLT for treatment or prophylaxis of leukemia relapse developed acute GVHD. IFN-gamma production by PBL stimulated by IL-12 plus anti-CD3 mAb increased, while IL-12 production by peripheral Mphi stimulated by LPS was very high after the development of acute GVHD. However, serum IL-12 concentration remained low. Three patients receiving DLT for EBV-LPD did not develop acute GVHD with no increase of IFN-gamma and IL-12 production. These results indicate that IL-12 may play an important role in the development of acute GVHD after allogeneic stem cell grafting or DLT, and increased IL-12 production by Mphi occurs with various stimuli, including LPS.

Abstract
AIM To examine the long term effect of bone marrow transplantation (BMT) on ovarian function in girls. METHODS Eighteen girls who underwent BMT before menarche, had been disease free for more than six years, and were over 14 years of age at the time of study were investigated. The preparative regimen consisted of irradiation and chemotherapy. The occurrence of menarche and changes in basal serum follicle stimulating hormone (FSH) concentrations were studied. RESULTS Twelve patients achieved menarche at a median age of 12.8 years. Age at transplant was significantly younger in patients who achieved menarche than in those who did not (mean (SD), 7.2 (0.5) v 11.1 (1.7) years). Basal FSH began to rise to menopausal concentrations after 10 years of age, and the girls who did not experience menarche had a sustained rise in FSH concentrations. Among those with raised FSH concentrations, five girls experienced menarche while serum FSH values were decreasing and four achieved menarche while FSH remained raised. CONCLUSIONS The high incidence of menarche suggests a favourable outcome of ovarian function in girls who undergo BMT at a young age.

Abstract
AIMS To establish whether MIB-1 and p53 staining are useful for differentiating pilocytic astrocytomas and astrocytomas from anaplastic astrocytomas and glioblastomas. This study was restricted to children and young adults under 30 years of age because of the differences in p53 mutations between paediatric and adult astrocytomas. METHODS AND RESULTS Forty-five astrocytic tumours, including 18 pilocytic astrocytomas, 14 astrocytomas, four anaplastic astrocytomas and nine glioblastomas, from 45 children and young adults, between 1 and 29 years (mean 11 years) of age, were examined pathologically, and sections from paraffin-embedded blocks were used for MIB-1 and p53 immunostaining. The MIB-1 labelling index and the frequency and intensity of p53 staining in both the pilocytic astrocytoma and the astrocytoma group were significantly lower than in the anaplastic astrocytoma plus glioblastoma group (P < 0.001). In 11.1% (two of 18) of pilocytic astrocytomas and 42.9% (six of 14) of astrocytomas, immunoreactivity of either MIB-1 or p53 staining was of almost the same intensity as that of anaplastic astrocytomas and glioblastomas. However, in these cases, results using both MIB-1 and p53 stain differed from those for anaplastic astrocytomas and glioblastomas. CONCLUSIONS MIB-1 and p53 co-staining is very useful for differentiating pilocytic astrocytomas and astrocytomas from anaplastic astrocytomas and glioblastomas. However, MIB-1 or p53 staining alone cannot differentiate pilocytic astrocytomas and astrocytomas from anaplastic astrocytomas and glioblastomas.

Abstract
The spike (S) protein of a non-fusogenic murine coronavirus, MHV-2, was compared to that of a variant, MHV-2f, with fusion activity. Two amino acids differed between The S proteins of these viruses; one was located in the signal sequence (amino acid 12) and the other in the putative cleavage site (amino acid 757). To determine which one of these amino acid changes is important for the alteration of fusogenicity, chimeric S proteins between MHV-2 and -2f were constructed and expressed in DBT cells by a vaccinia virus expression system. The results revealed that one amino acid change (Ser to Arg) at position 757 is responsible for the acquisition of fusogenicity of the MHV-2f S protein. This change also altered the susceptibility to proteolytic cleavage of the MHV-2 S protein which was originally uncleavable. We concluded that the non-fusogenic activity of MHV-2 results from the lack of cleavage of its S protein.

Abstract
The usefulness of RT-PCR for the detection of MHV in tissues and feces of experimentally infected animals has been reported, but it was unclear whether the method was also applicable for the detection of MHV during a natural outbreak. Enterotropic infection is considered to be the most common form of natural infection among various forms of MHV infection. In this paper, RT-nested PCR was performed to detect MHV excreted in the feces during an outbreak in an immunocompromised A/WySnJ mouse colony. The expected bands were amplified after nested PCR from 20 fecal samples out of 37. These results showed that RT-nested PCR could be applicable for the diagnosis for MHV natural infection.

Abstract
Thirty-five children with poor-prognosis disease underwent allogeneic bone marrow transplantation (BMT) from related donors other than HLA identical siblings (parents in 18 cases, non-identical siblings in 14, and other relatives in 3). Phenotypically identical donors were involved in 12 cases, donors with one mismatched locus in 17, and donors with two or more mismatched loci in 6. Thirty-two of the children received total-body irradiation as part of their conditioning regimen, followed by unpurged marrow-cell infusions (averaging 4.09 x 10(8) cells/kg). Methotrexate and cyclosporin were administered for graft-versus-host disease (GVHD) prophylaxis; 15 of the children also received antithymocyte globulin (ATG) infusions. The effective graft rate for the group was 84. 8%; of 5 patients who experienced rejections, 4 had non-malignant diseases. The incidence of grade II-IV acute GVHD was 48.4%, significantly higher than that for groups that received allogeneic BMT from matched sibling donors. Three children (8.8%) died of severe GVHD. The incidence of acute GVHD in phenotypically matched patients was the same as that in the one-locus mismatched cases. MLC reactivity affected the incidence of acute GVHD (60.0% MLC-positive, 28.6% negative). ATG reduced the severity of acute GVHD. The event-free survival rate was 40.8 +/- 8.5% for the entire group (N = 35; 32.9 +/- 10.5% for the 22 children with malignancies, and 53.8 +/- 13.8% for the 13 with non-malignant diseases). Despite the risk of severe GVHD, allogeneic BMT from related donors other than HLA-identical siblings seems to be an effective treatment for patients with poor-prognosis diseases.

Abstract
A myeloproliferative disease was found in a 128-day-old Holstein female calf. The tumour consisted chiefly of primitive cells, and more mature cells, many of which were positive for haemoglobin, were admixed with them. Binucleated cells at various stages of maturation were occasionally seen, and siderosomes were confirmed in both primitive cells and more mature cells by electron microscopy. The primitive cells resembled proerythroblasts, and this tumour, thought to be an acute type neoplasm of the erythroid system, was distinguishable from chronic erythremic myelosis and polycythemia vera.

Abstract
UNLABELLED In this study, we aimed to elucidate the effects of intrinsic nitric oxide (NO) on cardiac neural regulation. Twenty-two cats were anesthetized with 1.5% isoflurane and allocated to Group I (intact; n = 7), Group D (denervated baroreceptors and vagi; n = 8), or Group B (autonomic blockade with i.v. hexamethonium, propranolol, and atropine; n = 7). Cardiac sympathetic nerve activity (CSNA), mean arterial pressure (MAP), sinus heart rate (HR), and A-H and H-V intervals during pacing (150 bpm) were measured before and after i.v. administration of a NO synthase inhibitor, NG-nitro-L-arginine (L-NNA, 30 mg/kg) and after reversal with an excessive dose of L-arginine (300 mg/kg), before and during intermittent electrical stimulation of the posterior hypothalamus. L-NNA significantly increased MAP in Groups I and B, but not in Group D. L-NNA significantly decreased HR and lengthened A-H in Group I, but not in other groups. L-arginine further decreased HR and lengthened A-H unexpectedly. The reasons for these findings could not be determined in this study. L-NNA did not change CSNA. Hypothalamic stimulation did not potentiate L-NNA-induced changes in CSNA, hemodynamic variables, and atrioventricular conduction. In conclusion, intrinsic NO may modulate atrioventricular conduction and sinus rate through a vagal cholinergic, rather than a nonautonomic mechanism. IMPLICATIONS Elucidating the roles of intrinsic nitric oxide (NO) on cardiac neural regulation is important. In intact, vagotomized, and baroreceptor-denervated or pharmacologically autonomic blockaded cats, an NO synthesis inhibitor was administered, and atrioventricular conduction and cardiac sympathetic neural discharge were measured. The results suggest a vagal cholinergic mechanism of intrinsic NO.

Abstract
In our laboratory animal facility, Sendai virus (HVJ) contamination occurred in a negative flow rack used for experimental infection with 4 strains of mouse-adapted influenza virus (Inf.V). Anti-HVJ antibody (Ab) was detected in 35/42 mice in the rack. To specify the strain of Inf.V contaminated with HVJ, experimental infection was performed by using A, B and D strains of Inf.V in each vinyl isolator. Anti-HVJ Ab was detected in all mice infected with A strain at day 28 post-infection. As a result of experimental infection with A strain of Inf.V which was treated with anti-HVJ mouse serum, the virus suspension was determined not to contain HVJ and allowed for experimental use in our facility, Since then, HVJ contamination has not occurred in our facility.

Abstract
A 28-year-old primipara with pulmonary embolism due to deep venous thrombosis was scheduled for cesarean section under general anesthesia. Her Swan-Ganz catheter and blood gas data revealed pulmonary hypertension and hypoxemia, respectively. Heparin was discontinued 6 hours before operation. A transesophageal echocardiogram (TEE) probe and an inferior vena cava filter were inserted before surgery. Anesthesia was maintained with nitrous oxide and isoflurane in oxygen before delivery, and after delivery with nitrous oxide in oxygen, fentanyl and midazolam. Nitroglycerin and prostaglandin E1 were administered before and after delivery, respectively, to control pulmonary artery pressure, although they were not effective. The anesthetic course was uneventful and her baby's Apgar scores were satisfactory. Mean pulmonary artery pressure (MPAP) gradually decreased after surgery. The inferior vena cava filter may be effective in preventing new pulmonary embolism, and MPAP and TEE monitoring are useful for early detection of pulmonary emboli.

Abstract
The cDNA encoding interleukin-2 (IL-2) of cynomolgus monkey was molecularly cloned from concanavalin-A-stimulated peripheral lymphocyte cDNA by the reverse transcription-polymerase chain reaction method. Cynomolgus monkey IL-2 cDNA displays a high degree of homology with the human equivalent both at nucleic acid (98%) and amino acid (96%) sequence levels, although having only one additional amino acid residue. Recombinant monkey IL-2 secreted by insect cells infected with the recombinant baculovirus migrated as two distinct bands with 15 and 18 kD corresponding to mature and precursor IL-2 molecules, respectively, which were revealed to cross-react with anti-human IL-2 polyclonal antibody in Western blot analysis. This monkey IL-2 exhibited high biological activity up to an order of 10(6) U/ml as assessed by an IL-2-dependent cell proliferation assay and was shown to be neutralized by anti-human IL-2 antibody.

Abstract
A five-year-old girl with Diamond-Blackfan syndrome received cord blood transplantation from an HLA-identical sibling. The patient showed pale face at birth, and was diagnosed to have Diamond-Blackfan syndrome. She had been treated with prednisolone (PSL), high dose of methylprednisolone, erythropoietin, and anti-lymphocyte globulin. Despite of these intensive therapies, erythropoiesis did not entirely improve, and transfusion of red blood cells had been required every third or fourth week until cord blood transplantation. Conditioning regimen consisted of thoraco-abdominal irradiation (TAI; 8 Gy), cyclophosphamide (CY; 50 mg/kg x 4), and anti-thymocyte globulin (ATG; 2.5 mg/kg x 4), Cyclosporin (CyA 3 mg/kg) was administered for the prophylaxis of graft-versus-host disease (GVHD). 4.14 x 10 (7)/kg of cord blood mononuclear cells were infused to the patient. White blood cell (WBC) and reticulocyte counts increased promptly, but recovery of platelet count was delayed. Skin GVHD (grade I) appeared on day +9, which responded to the administration of PSL (2 mg/kg). Chromosomal analyses of bone marrow cells for sex mismatch revealed complete chimerism on day +14, on day +28 and thereafter. Umbilical cord blood cells can be an alternative source of hematopoietic stem cells for allogeneic transplantation.

Abstract
Chronic restrictive lung disease in a 9-year-old boy with dyskeratosis congenita (DC) 7 years after allogeneic bone marrow transplantation (BMT) is described. When he was 1 year and 10 months old, severe aplastic anemia developed. He received a marrow transplant from his HLA serologically identical, but HLA-DP mismatched brother. He developed grade II acute graft-versus-host disease (GVHD) and thereafter chronic GVHD of progressive type, and was treated with both prednisolone and azathioprine resulting in clinical improvement. Thereafter he complained of dyspnea, and bilateral noncircumscribed interstitial shadows on chest CT scan were present. His pulmonary function showed restrictive changes. Prednisolone was not effective and he died of respiratory failure. Post-mortem examination confirmed interstitial fibrosis, lymphocytic infiltration of the bronchioles and alveoli with luminal fibrosis. There was no evidence of chronic GVHD in the skin and the liver. These findings raise the possibility that this pulmonary complication was associated with DC itself.

Abstract
The spike (S) protein of a nonfusogenic murine coronavirus, MHV-2, was compared to the S protein of a variant with fusion activity, MHV-2f. Two amino acids differed between the S proteins of these viruses; one was located in the signal sequence and the other was in the putative cleavage site. The amino acid at position 12 in the signal sequence was S in MHV-2 and C in MHV-2f. The amino acid sequence of the cleavage site of MHV-2 was HRARS, while that of MHV-2f was HRARR, showing one amino acid replacement at position 757. In DBT cells infected with MHV-2, the S protein was not cleaved, while the S protein of MHV-2f was cleaved. The S protein of MHV-2f expressed in a transient vaccinia virus expression system was cleaved and was fusogenic in contrast to the nonfusogenic activity of uncleaved MHV-2 S protein. Because the signal sequence is assumed to be removed from the mature S protein soon after synthesis, and because the S protein of MHV-2 was expressed on the cell surface in the same way as the S protein of MHV-2f, the difference in the signal sequence seemed to have had little effect on the transportation and the fusion activity of the S protein. These results showed that MHV-2 does not fuse cells due to the lack of cleavage of its S protein. This conclusion differs from studies on the activity of syncytium formation by the S proteins of fusogenic MHV-JHM and -A59 strains. Possible reasons for these differences in fusion activity are discussed.

Abstract
In a randomized double-blind study, the use of continuous epidural lidocaine during surgery combined with preoperative epidural morphine was compared with that of preoperative epidural morphine alone for postoperative analgesia in 20 patients undergoing hepatectomy. Morphine 2 mg was administered through a catheter inserted epidurally at T10-11 before surgery, followed by continuous epidural administration of 1% lidocaine 5ml.h-1 in group Lid (n = 10) or normal saline 5ml.h-1 in group NS (n = 10) during surgery. Anesthesia was maintained with N2O-O2-isoflurane in both groups. On admission to the ICU, the visual analog scale score (VAS; mm) was 20 +/- 7 (mean +/- SE) in group Lid and 38 +/- 10 in group NS, and the number of patient with VAS < or = 30 was 9 in group Lid and 4 in group NS; these differences were significant (P < 0.05). Pain score during mobilization in group Lid was significantly lower than that in group NS (P < 0.05). All patients in both groups had adequate analgesia for the remainder of their stay in the ICU. No patient had any serious adverse effect. We conclude that continuous epidural administration of lidocaine during hepatectomy combined with administration of epidural morphine just before surgery results in better pain relief during the early postoperative period than that obtained with epidural morphine alone, and is without serious side effects.

Abstract
A five-year-old boy with acute myelogenous leukemia in relapse was treated by HLA-matched cord blood stem cell transplantation. The patient was preconditioned with 16 mg/kg of busulfan, 15 mg/kg of thiotepa and 90 mg/kg of cyclophosphamide and 2.45 x 10(7)/kg of cord blood mononuclear cells were infused to the patient on October 19th 1995 without the prophylaxis of graft-versus-host disease (GVHD). From the fifth day following the transplant, rG-CSF was administered at a dose of 300 micrograms/m2/day. Hematopoietic recovery was obtained as following; WBC over 1000/microliters was on +18 day, neutrophil over 500/microliters was on +20 day, reticulocyte over 20/1000 was on +28 day and platelet over 50 x 10(2) microliters was on +91 day. Engraftment was confirmed by DNA restriction fragment length polymorphism (VNTR) on +28 day. In spite of absence of prophylaxis of GVHD, the patient did not develop any signs of GVHD, and leukemia relapsed on +105 day. The patient died of leukemia relapse on +251 day. This is the first case of cord blood stem cell transplantation in Japan.

Abstract
The CD34 antigen is expressed on pluripotent stem cells and the CD34+ cell has been shown to be capable of hematopoietic reconstitution in animal and human autologous grafts. We asked if CD34+ cells could reconstitute hematopoiesis in human allogeneic transplantation from a HLA-mismatched donor. Three pediatric patients with advanced leukemia received allogeneic CD34-enriched marrow cell graft from HLA two (two patients) or three (one patient) loci-mismatched parental donors. CD34+ cell selection was performed with mouse anti-CD34 antibody 9C5 and magnetic beads coated sheep anti-mouse IgG1. 1.53 to 2.48 x 10(9) marrow cells were processed and 2.53 to 7.89 x 10(7) positively selected cells were recovered. The selected population showed 93.7 to 99.0% CD34+ cells and total recovery of CD34+ cells from the starting population was 54.6 to 62.3%. CD34+ cell selection resulted in more than 99.9% depletion of CD5+ cells from the bone marrow. The patients received 2.53 to 7.25 x 10(6) CD34-enriched cells/kg after myeloablative therapy. All patients achieved trilineage engraftment that was confirmed by various genetic markers. Acute graft-versus-host disease (GVHD) was grade 0 (two patients) or grade I (one patient), and hematological recovery was successfully achieved as follows; the days to reach granulocytes over 0.5 x 10(9)/I were 11 to 13 days, reticulocytes over 2% was 18 to 28 days, platelets over 50 x 10(9)/I was 33 to 58 days. One patient is surviving without relapse of leukemia and two patients died after either mixed hematopoietic chimerism or leukemia relapse was observed. These studies suggest that CD34+ marrow cells are capable of hematopoietic reconstitution from HLA two or three loci-mismatched donors even with the lowest dose of mature T cells.
