Abstract
PURPOSE During the last decade, the incidence of anaerobic bacteremia (AB) has been increasing. Patients with AB may develop complex underlying diseases, which can occasionally be accompanied by fatal or fulminant outcomes. However, the risk factors for AB-related mortality remain unclear. Herein, we sought to elucidate the risk factors for AB-related mortality. METHODS In this multicenter, retrospective, observational study, we enrolled patients with culture-proven AB from six tertiary hospitals in Japan, between January 2012 and December 2021. Data on patient and infection characteristics, laboratory findings, treatment, and outcome were collected, and their associations with mortality were analyzed. RESULTS A total of 520 participants were included. The 30-day mortality in the study cohort was 14.0% (73 patients), and malignant tumors were frequently observed comorbidities in 48% of the entire cohort. Multivariable logistic regression analysis showed a Charlson comorbidity score of > 6, serum creatinine level of > 1.17 mg/dL, and hypotension to be independent risk factors for 30-day mortality in AB (odds ratios [ORs] 2.12, 2.25, and 5.12, respectively; p < 0.05), whereas drainage significantly reduced this risk (OR, 0.28; p < 0.0001). Twelve patients (2.3% of the whole cohort and 16.4% of the deceased patients) presented with extremely rapid progression leading to fatal outcome, consistent with "fulminant AB." CONCLUSIONS This study identified acute circulatory dysfunction and performance of drainage as independent predictive factors for 30-day AB-related mortality and revealed the existence of a fulminant AB sub-phenotype. Our findings could serve as a practical guide to predict the clinical outcomes of AB.

Abstract
BACKGROUND Endoplasmic reticulum (ER) stress has a close relation with cancer progression. Blocking the adaptive pathway of ER stress could be an anticancer strategy. Here, we identified an ER stress-related gene, Transducin beta-like 2 (TBL2), an ER-localized type I transmembrane protein, on increased chromosome 7q as a candidate driver gene of lung adenocarcinoma (LUAD). METHODS The association between TBL2 mRNA expression and prognostic outcomes and clinicopathological factors was analyzed using The Cancer Genome Atlas (TCGA) datasets of LUAD and lung squamous cell carcinoma (LUSC). Localization of TBL2 in tumor tissues was observed by immunohistochemical staining. Gene set enrichment analysis (GSEA) was conducted using TCGA dataset. In vitro cell proliferation assays were performed using TBL2 knockdown LUAD cells, LUSC cells, and LUAD cells overexpressing TBL2. Apoptosis and ATF4 expression (ER stress marker) were evaluated by western blotting. RESULTS TBL2 was overexpressed in LUAD and LUSC cells. Multivariate analysis indicated high TBL2 mRNA expression was an independent poor prognostic factor of LUAD. GSEA revealed high TBL2 expression was positively correlated to the ER stress response in LUAD. TBL2 knockdown attenuated LUAD cell proliferation under ER stress. TBL2 inhibited apoptosis in LUAD cells under ER stress. TBL2 knockdown reduced ATF4 expression under ER stress. CONCLUSIONS TBL2 may be a novel driver gene that facilitates cell proliferation, possibly by upregulating ATF4 expression followed by adaptation to ER stress, and it is a poor prognostic biomarker of LUAD.

Abstract
BACKGROUND Driver alterations may represent novel candidates for driver gene-guided therapy; however, intrahepatic cholangiocarcinoma (ICC) with multiple genomic aberrations makes them intractable. Therefore, the pathogenesis and metabolic changes of ICC need to be understood to develop new treatment strategies. We aimed to unravel the evolution of ICC and identify ICC-specific metabolic characteristics to investigate the metabolic pathway associated with ICC development using multiregional sampling to encompass the intra- and inter-tumoral heterogeneity. METHODS We performed the genomic, transcriptomic, proteomic and metabolomic analysis of 39-77 ICC tumour samples and eleven normal samples. Further, we analysed their cell proliferation and viability. RESULTS We demonstrated that intra-tumoral heterogeneity of ICCs with distinct driver genes per case exhibited neutral evolution, regardless of their tumour stage. Upregulation of BCAT1 and BCAT2 indicated the involvement of 'Val Leu Ile degradation pathway'. ICCs exhibit the accumulation of ubiquitous metabolites, such as branched-chain amino acids including valine, leucine, and isoleucine, to negatively affect cancer prognosis. We revealed that this metabolic pathway was almost ubiquitously altered in all cases with genomic diversity and might play important roles in tumour progression and overall survival. CONCLUSIONS We propose a novel ICC onco-metabolic pathway that could enable the development of new therapeutic interventions.

Abstract
BACKGROUND Immunotherapy has become a standard-of-care for patients with non-small-cell lung cancer (NSCLC). Although several biomarkers, such as programmed cell death-1, have been shown to be useful in selecting patients likely to benefit from immune checkpoint inhibitors (ICIs), more useful and reliable ones should be investigated. The prognostic nutritional index (PNI) is a marker of the immune and nutritional status of the host, and is derived from serum albumin level and peripheral lymphocyte count. Although several groups reported its prognostic role in patients with NSCLC receiving a single ICI, there exist no reports which have demonstrated its role in the first-line ICI combined with or without chemotherapy. MATERIALS AND METHODS Two-hundred and eighteen patients with NSCLC were included in the current study and received pembrolizumab alone or chemoimmunotherapy as the first-line therapy. Cutoff value of the pretreatment PNI was set as 42.17. RESULTS Among 218 patients, 123 (56.4%) had a high PNI (≥42.17), while 95 (43.6%) had a low PNI (<42.17). A significant association was observed between the PNI and both the progression-free survival (PFS; hazard ratio [HR] = 0.67, 95% confidence interval [CI]: 0.51-0.88, p = 0.0021) and overall survival (OS; HR = 0.46, 95% CI: 0.32-0.67, p < 0.0001) in the entire population, respectively. The multivariate analysis identified the pretreatment PNI as an independent prognosticator for the PFS (p = 0.0011) and OS (p < 0.0001), and in patients receiving either pembrolizumab alone or chemoimmunotherapy, the pretreatment PNI remained an independent prognostic factor for the OS (p = 0.0270 and 0.0006, respectively). CONCLUSION The PNI might help clinicians appropriately identifying patients with better treatment outcomes when receiving first-line ICI therapy.

Abstract
OBJECTIVES Sarcopenia correlates with poor prognosis in various malignancies. However, the prognostic significance of sarcopenia remains to be determined in patients with non-small-cell lung cancer who undergo surgery after receiving neoadjuvant chemoradiotherapy (NACRT). METHODS We retrospectively reviewed the patients with stage II/III non-small-cell lung cancer who underwent surgery following NACRT. The paravertebral skeletal muscle area (SMA) (cm2) at the 12th thoracic vertebra level was measured. We calculated the SMA index (SMAI) as SMA/squared height (cm2/m2). Patients were divided into low and high SMAI groups, and the association of SMAI with clinicopathological factors and prognosis was assessed. RESULTS The patients' [men, 86 (81.1%)] median age was 63 (21-76) years. There were 106 patients including 2 (1.9%), 10 (9.4%), 74 (69.8%), 19 (17.9%) and 1 (0.9%) patients with stage IIA, IIB, IIIA, IIIB and IIIC, respectively. Of the patients, 39 (36.8%) and 67 (63.2%) were classified in the low and the high SMAI groups, respectively. Kaplan-Meier analysis showed that the low group had a significantly shorter overall survival and disease-free survival than the high group. Multivariable analysis identified low SMAI as an independent poor prognostic factor for overall survival. CONCLUSIONS Pre-NACRT SMAI correlates with poor prognosis; therefore, assessing sarcopenia based on pre-NACRT SMAI may help determine optimal treatment strategies and suitable nutritional and exercise interventions.

Abstract
AbstractDrugs are expected to recover the cell system away from the impaired state to normalcy through disease treatment. However, the understanding of gene regulatory machinery underlying drug activity or disease pathogenesis is far from complete. Here, we perform large-scale regulome analysis for various diseases in terms of gene regulatory machinery. Transcriptome signatures were converted into regulome signatures of transcription factors by integrating publicly available ChIP-seq data. Regulome-based correlations between diseases and their approved drugs were much clearer than the transcriptome-based correlations. For example, an inverse correlation was observed for cancers, whereas a positive correlation was observed for immune system diseases. After demonstrating the usefulness of the regulome-based drug discovery method in terms of accuracy and applicability, we predicted new drugs for nonsmall cell lung cancer and validated the anticancer activity in vitro. The proposed method is useful for understanding disease–disease relationships and drug discovery.

Abstract
BACKGROUND Extrapulmonary tuberculosis commonly affects the lymphatic system, nervous system, and gastrointestinal system. Tuberculous infection in the muscle is very rare. Moreover, tuberculous infection in the diaphragm is extremely rare. We herein report a case of tuberculomas in the diaphragm and posterior mediastinum that were successfully diagnosed and treated. CASE PRESENTATION We encountered a 62-year-old woman with a tuberculoma in the diaphragm. The patient presented with mild dyspnea. Computed tomography showed a mass in the left diaphragm, focal thickening of the posterior mediastinum, and multiple nodules in the lungs. Positron emission tomography-computed tomography showed increased uptake in the left diaphragm mass and thickening of the posterior mediastinum; therefore, we considered the masses to be malignant and planned surgical resection. However, the patient was diagnosed with tuberculosis from a sputum culture, and she was treated with anti-tuberculous therapy. The masses in the diaphragm and posterior mediastinum had become enlarged after 6 months of anti-tuberculous therapy; therefore, the patient underwent resection of both masses. Tuberculous infection was histologically confirmed in each lesion. She was pathologically diagnosed with tuberculous abscesses in the diaphragm and posterior mediastinum and began treatment with anti-tuberculosis drugs. CONCLUSIONS Preoperative diagnosis of a tuberculoma in the diaphragm is usually difficult, and surgical intervention is important for both diagnosis and treatment.

Abstract
BACKGROUND Preoperative maximum standardized uptake value (SUVmax) of 2-[18F]-fluoro-2-deoxy-D-glucose positron emission tomography and serum carcinoembryonic antigen (CEA) have been reported as prognostic factors for lung adenocarcinoma. However, the significance of combined SUVmax and CEA in early-stage lung adenocarcinoma is not well known. METHODS We retrospectively evaluated the relationship between the combination of SUVmax and CEA and the prognosis of 410 patients with clinical stage IA lung adenocarcinoma who underwent resection. The cutoff values for SUVmax and CEA were determined by receiver operating characteristic curve analysis, and patients were categorized into high SC (SUVmax and CEA) group (SUVmax ≥2.96 and CEA ≥5.3), moderate SC group (either SUVmax <2.96 and CEA ≥5.3 or SUVmax ≥2.96 and CEA <5.3) and low SC group (SUVmax <2.96 and CEA <5.3). RESULTS Kaplan-Meier curve analysis showed that patients with clinical stage IA lung adenocarcinoma in the high SC group had significantly shorter overall survival (OS) and recurrence-free survival (RFS) than the other groups (p = 0.011 and p < 0.0001, respectively). Multivariate analysis showed that high SC was an independent prognostic factor of OS (p = 0.029) and RFS (p < 0.0001). CONCLUSIONS High values of SUVmax and CEA were associated with poor OS and RFS in patients with stage IA lung adenocarcinoma. Simultaneous evaluation of SUVmax and CEA may be an effective prognostic marker to determine the optimal treatment strategy of early-stage lung adenocarcinoma.

Abstract
Non-small-cell lung cancer (NSCLC) with epidermal growth factor receptor (EGFR) mutations is highly sensitive to EGFR-tyrosine kinase inhibitor (EGFR-TKI). However, few cases of advanced NSCLC completely cured by EGFR-TKIs have been reported. We present an extremely rare case of lung adenocarcinoma that was completely cured by gefitinib administration. A 36-year-old Japanese woman was diagnosed with clinical Stage IIIB (T2N3M0) lung adenocarcinoma originating from the left upper lobe in April 2006. After the two cycles of chemotherapy, it was down-staged to ycStage IA (T1N0M0). She underwent a thoracotomy with left upper lobectomy, pulmonary angioplasty, and mediastinal nodal dissection in July 2006 [ypStage IIIA (T3N1M0)]. Eighteen months later, she was found to have lymphadenopathy of the right supraclavicular nodes. Fine needle aspiration cytology of the lymph node indicated adenocarcinoma. She started gefitinib therapy for recurrent lung cancer with EGFR mutation (exon 19 deletion) in January 2008. Four months afterward, computed tomography (CT) showed her right supraclavicular nodes had shrunk dramatically. Treatment with gefitinib was continued. Thereafter, no disease progression was observed throughout her approximately 8-year gefitinib treatment, and gefitinib was terminated in November 2016. Although the patient received no other treatment, she has suffered no recurrence in the 4 years since. A review of the literature, including our case, is also presented.

Abstract
INTRODUCTION Fanconi anemia complementation group E (FANCE) is a Fanconi anemia (FA) pathway gene that regulates DNA repair. We evaluated the clinical relevance of FANCE expression in hepatocellular carcinoma (HCC). METHODS First, the associations between the expression of FA pathway genes including FANCE and clinical outcomes in HCC patients were analyzed in two independent cohorts: The Cancer Genome Atlas (TCGA, n = 373) and our patient cohort (n = 53). Localization of FANCE expression in HCC tissues was observed by immunohistochemical staining. Gene set enrichment analysis (GSEA) and gene network analysis (SiGN_BN) were conducted using the TCGA dataset. Next, an in vitro proliferation assay was performed using FANCE-knockdown HCC cell lines (HuH7 and HepG2). The association between mRNA expression of FANCE and that of DNA damage response genes in HCC was analyzed using TCGA and Cancer Cell Line Encyclopedia datasets. Finally, the association between FANCE mRNA expression and overall survival (OS) in various digestive carcinomas was analyzed using TCGA data. RESULTS FANCE was highly expressed in HCC cells. Multivariate analysis indicated that high FANCE mRNA expression was an independent factor predicting poor OS. GSEA revealed a positive relationship between enhanced FANCE expression and E2F and MYC target gene expression in HCC tissues. FANCE knockdown attenuated the proliferation of HCC cells, as well as reduced cdc25A expression and elevated histone H3 pSer10 expression. SiGN_BN revealed that FANCE mRNA expression was positively correlated with DNA damage response genes (H2AFX and CHEK1) in HCC tissues. Significant effects of high FANCE expression on OS were observed in hepatobiliary pancreatic carcinomas, including HCC. CONCLUSIONS FANCE may provide a potential therapeutic target and biomarker of poor prognosis in HCC, possibly by facilitating tumor proliferation, which is mediated partly by cell cycle signaling activation.

Abstract
BACKGROUND/AIM Albumin-bilirubin (ALBI) grade is an indicator of liver dysfunction and is useful for predicting postoperative prognosis of hepatocellular carcinomas. However, the significance of ALBI grade in non-small cell lung carcinoma (NSCLC) has not been elucidated. PATIENTS AND METHODS We analyzed 947 patients with pStage IA-IIIA NSCLC. We divided patients into ALBI grade 1 and grade 2/3 groups. We then analyzed the association of ABLI grade with clinicopathological characteristics and prognosis in NSCLC by using propensity-score matching. RESULTS ALBI grade 2/3 was significantly associated with older age, male sex, advanced pT status, and histological type. Even after propensity-score matching, ALBI grade 2/3 patients had significantly worse cancer-specific survival (CSS) than ALBI grade 1 patients (5-year CSS: 87.3% versus 92.8%; p=0.0247). In multivariate analysis, ALBI grade 2/3 was an independent predictor of CSS (HR=1.9; 95%CI=1.11-3.11; p=0.0177). CONCLUSION ALBI grade was an independent prognostic factor in surgically resected NSCLC.

Abstract
Targeting mutated oncogenes is an effective approach for treating cancer. The 4 main driver genes of pancreatic ductal adenocarcinoma (PDAC) are KRAS, TP53, CDKN2A, and SMAD4, collectively called the "big 4" of PDAC, however they remain challenging therapeutic targets. In this study, ArfGAP with SH3 domain, ankyrin repeat and PH domain 2 (ASAP2), one of the ArfGAP family, was identified as a novel driver gene in PDAC. Clinical analysis with PDAC datasets showed that ASAP2 was overexpressed in PDAC cells based on increased DNA copy numbers, and high ASAP2 expression contributed to a poor prognosis in PDAC. The biological roles of ASAP2 were investigated using ASAP2-knockout PDAC cells generated with CRISPR-Cas9 technology or transfected PDAC cells. In vitro and in vivo analyses showed that ASAP2 promoted tumor growth by facilitating cell cycle progression through phosphorylation of epidermal growth factor receptor (EGFR). A repositioned drug targeting the ASAP2 pathway was identified using a bioinformatics approach. The gene perturbation correlation method showed that niclosamide, an antiparasitic drug, suppressed PDAC growth by inhibition of ASAP2 expression. These data show that ASAP2 is a novel druggable driver gene that activates the EGFR signaling pathway. Furthermore, niclosamide was identified as a repositioned therapeutic agent for PDAC possibly targeting ASAP2.

Genome-wide analysis is widely applied to detect molecular alterations during oncogenesis and tumor progression. We analyzed DNA methylation profiles of hepatocellular carcinoma (HCC), and investigated the clinical role of most heypermethylated of tumor, encodes T-box 15 (TBX15), which was originally involved in mesodermal differentiation. We conducted a genome-wide analysis of DNA methylation of tumor and non-tumor tissue of 15 patients with HCC, and revealed TBX15 was the most hypermethylated gene of tumor (Beta-value in tumor tissue = 0.52 compared with non-tumor tissue). Another validation set, which comprised 58 HCC with radical resection, was analyzed to investigate the relationships between tumor phenotype and TBX15 mRNA expression. TBX15 mRNA levels in tumor tissues were significantly lower compared with those of nontumor tissues (p < 0.0001). When we assigned a cutoff value = 0.5-fold, the overall survival 5-year survival rates of the low-expression group (n = 17) were significantly shorter compared with those of the high-expression group (n = 41) (43.3% vs. 86.2%, p = 0.001). Multivariate analysis identified low TBX15 expression as an independent prognostic factor for overall and disease-free survival. Therefore, genome-wide DNA methylation profiling indicates that hypermethylation and reduced expression of TBX15 in tumor tissue represents a potential biomarker for predicting poor survival of patients with HCC.

Abstract
BACKGROUND/AIM Programmed death-ligand 1 (PD-L1/CD274) elicits T-cell anergy, leading to immune suppression. We aimed to determine the prognostic relevance of PD-L1 expression in the blood of breast cancer (BC) patients. MATERIALS AND METHODS We measured PD-L1 mRNA expression in blood and tumor tissues of BC patients using RT-qPCR and a dataset from The Cancer Genome Atlas, and performed a survival analysis of PD-L1 expression in the blood of 330 BC patients. Flow cytometric analysis was performed using blood cells. RESULTS No statistical difference in PD-L1 expression was seen between normal controls and BC in blood or tissues. There was a significant positive correlation between the PD-L1 expression levels in blood and tissues. Decreased PD-L1 expression in blood or tissues was associated with poor recurrence-free survival. PD-L1 is mainly expressed in polymorphonuclear leukocytes. CONCLUSION Low expression of PD-L1 in the blood could serve as a biomarker of poor prognosis in BC patients.

Abstract
BACKGROUND Interleukin (IL)-38 was discovered in 2001 and is a member of the IL-1 family of cytokines. IL-38 shows anti-inflammatory activity in several inflammatory diseases. In lung adenocarcinoma, we previously demonstrated that high IL-38 expression in tumor cells was associated with poor prognosis. However, the role of IL-38 in the tumor microenvironment has not been clarified. METHODS IL-38-plasmid-transfected Lewis lung carcinoma cells (LLC-IL38) and empty vector-transfected LLC cells (LLC-vector) were established. Cell proliferation in vitro and tumor growth in vivo were examined, and immunohistochemical staining was used to assess tumor-infiltrating lymphocytes (TILs). A CD8+ lymphocyte depletion model was established to show the association between IL-38 and CD8+ lymphocytes. Moreover, we examined the association between IL-38 expression and CD8+ TILs in human samples, analyzing immunohistochemical staining in 226 patients with radically resected lung adenocarcinoma. RESULTS Tumor growth of LLC-IL38 in vivo was significantly increased compared with that of LLC-vector, although cell proliferation of LLC-IL38 in vitro was lower than that of LLC-vector. CD8+ TILs were significantly decreased in LLC-IL38 tumor compared with LLC-vector tumor. The difference in tumor growth between LLC-IL38 and LLC-vector became insignificant after depletion of CD8+ lymphocytes. In immunohistochemical staining in tissues from patients with lung adenocarcinoma, multivariate analysis showed high IL-38 expression was an independent negative predicter of high density of CD8+ TILs. CONCLUSION We demonstrated that high IL-38 expression in tumor cells was significantly associated with reduction of CD8+ TILs and tumor progression. These results suggest that IL-38 could be a therapeutic target for lung cancer.

Abstract
BACKGROUND Immunotherapy has become a standard treatment option for non-small cell lung cancer (NSCLC), with the tumor microenvironment attracting significant attention. CD8 + and forkhead box protein P3 + (FoxP3 +) tumor-infiltrating lymphocytes (TILs) influence the tumor microenvironment, but the clinical significance of CD8 + and FoxP3 + TILs in stage IA lung adenocarcinoma (LAD) is poorly understood. METHODS We analyzed 203 patients with stage IA primary LAD who had undergone surgery at Kyushu University from January 2003 to December 2012. We evaluated CD8 + and FoxP3 + TILs by immunohistochemistry. We set the cutoff values at 50 cells/0.04 mm2 for CD8 + TILs and 20 cells/0.04 mm2 for FoxP3 + TILs, respectively. We divided the patients into four groups: CD8-Low/FoxP3-Low; CD8-High/FoxP3-Low; CD8-Low/FoxP3-High; and CD8-High/FoxP3-High. We compared clinical outcomes among them. Programmed cell death ligand-1 (PD-L1) expression by tumor cells was also evaluated as previously reported. RESULTS Respectively, 104 (51.2%), 46 (22.7%), 22 (10.8%), and 31 (15.3%) patients were classified as CD8-Low/FoxP3-Low, CD8-High/FoxP3-Low, CD8-Low/FoxP3-High, and CD8-High/FoxP3-High. Both disease-free survival (DFS) and overall survival (OS) were significantly worse in the CD8-Low/FoxP3-High group than the other groups (5-year DFS: 66.3% vs. 90.5%; P = 0.0007, 5-year OS: 90.9% vs. 97.0%; P = 0.0077). In the multivariate analysis, CD8-Low/FoxP3-High and PD-L1 expression were independent prognostic factors of DFS, and lymphatic invasion, surgical procedure, and PD-L1 expression were independent prognostic factors of OS. CONCLUSIONS CD8-Low/FoxP3-High was an independent prognostic factor of DFS (hazard ratio: 3.22; 95% confidence interval: 1.321-7.179; P = 0.0121) in stage IA LAD. Immunosuppressive conditions were associated with poor prognosis in stage IA LAD.

Abstract
AIMS Oral administration of probiotics has been known to improve inflammatory responses against infectious diseases. Here, we describe the inhibitory effect of oral intake of heat-killed Lactobacillus pentosus strain b240 (b240) on pneumococcal pneumonia in a murine experimental model. METHOD AND RESULTS The mice treated with oral b240 for 21 days before Streptococcus pneumoniae infection exhibited prolonged survival time and less body weight loss, compared with saline-treated control mice. Mild pneumonia with significantly reduced secretion of inflammatory cytokines/chemokines according to related mitogen-activated protein kinase signalling molecules (phosphorylated c-Jun N-terminal kinase) was found in b240-treated mice, whereas severe pneumonia with hypercytokinemia was evident in control mice. Prominent reduction in the number of pneumococci and elevated expression of Toll-like receptor 2 and 4 in the lung tissues was concomitantly noted in b240-treated mice. CONCLUSIONS These findings indicate that b240 has inhibitory effects on pneumococcal pneumonia induced by Strep. pneumoniae infection and improves inflammatory tissue responses, resulting in reduced damages to the respiratory tissues. SIGNIFICANCE AND IMPACT OF THE STUDY These results demonstrate that oral administration of b240 might protect host animals from Strep. pneumoniae infection by augmentation of innate immune response.

Abstract
Gabexate mesilate is a synthetic protease inhibitor that is effective for acute pancreatitis. The effect of gabexate mesilate in influenza pneumonia in mice was investigated by examining the changes in pulmonary inflammatory cytokines and chemokines. Pathological changes in the lungs of treated mice were extremely mild, compared with changes in infected, untreated mice. Intrapulmonary levels of interleukin-6 and macrophage inflammatory protein-2 decreased in treated mice compared with untreated mice, despite similar viral titres in the lungs. Survival terms for treated and untreated groups were similar. These data indicate that gabexate mesilate has beneficial effects on influenza pneumonia, which may be due to the modulation of inflammatory cytokine/chemokine responses.

Abstract
Severe pneumonia is found in simultaneous influenza pneumonia and bacterial infection, and suggests a relationship with immunological mechanisms. Here, we performed two-dimensional gel electrophoresis to detect immunological molecules related to the fulminant pneumonia caused by influenza virus and Streptococcus pneumoniae co-infection in mice. We found two spots that were expressed strongly in co-infected mouse lungs, compared with S. pneumoniae or influenza virus singly infected mouse lungs. The spots were analysed by mass spectrometry, and identified as alpha-1 anti-trypsin (A1AT), known as an anti-protease for neutrophil-derived proteolytic enzymes, and creatine kinase, which reflects a greater degree of lung damage and cell death. A1AT expression was increased significantly, and proteolytic enzymes from neutrophils, such as neutrophil elastase, myeloperoxidase and lysozyme, were also secreted abundantly in influenza virus and S. pneumoniae co-infected lungs compared with S. pneumoniae or influenza virus singly infected lungs. These data suggest that A1AT may play a central role as a molecule with broad anti-inflammatory properties, and regulation of the neutrophil-mediated severe lung inflammation is important in the pathogenesis of co-infection with influenza virus and bacteria.

Abstract
Despite the enormous potential of conditionally replicating adenoviruses (CRAs), the time-consuming and laborious methods required to construct CRAs have hampered both the development of CRAs that can specifically target tumors with multiple factors (m-CRA) and the efficient analysis of diverse candidate CRAs. Here, we present a novel method for efficiently constructing diverse m-CRAs. Elements involving viral replication, therapeutic genes, and adenoviral backbones were separately introduced into three plasmids of P1, P2, and P3, respectively, which comprised different antibiotic resistant genes, different ori, and a single loxP (H) sequence. Independently constructed plasmids were combined at 100% accuracy by transformation with originally prepared Cre and specific antibiotics in specific Escherichia coli; transfection of the resulting P1+2+3 plasmids into 293 cells efficiently generated m-CRAs. Moreover, the simultaneous generation of diverse m-CRAs was achieved at 100% accuracy by handling diverse types of P1+2 and P3. Alternatively, co-transfection of P1+3 and P2 plasmids into Cre-expressing 293 cells directly generated m-CRA with therapeutic genes. Thus, our three-plasmid system, which allows unrestricted construction and efficient fusion of individual elements, should expedite the process of generating, modifying, and testing diverse m-CRAs for the development of the ideal m-CRA for tumor therapy.

Abstract
To examine the relationship between the plasma levels of angiogenic growth factors and the severity of cyanosis, 80 patients with cyanotic heart disease (CHD) and 81 healthy controls were studied. Median age and mean arterial blood oxygen saturation respectively were 4.2 years and 81% in CHD subjects and 4.8 years and 98% in controls. Vascular endothelial growth factor (VEGF) and hepatocyte growth factor (HGF) were measured in plasma using enzyme-linked immunoassay. Plasma VEGF levels in controls depended negatively on age (p < 0.0001) until 3 months, when VEGF was no longer elevated. No such age dependence was found for HGF. Although VEGF levels did not differ between CHD and control subjects up to the age of 3 months, VEGF was significantly elevated in CHD patients older than 3 months compared to controls of similar age (149 +/- 106 vs 65 +/- 23 pg/ml, p < 0.0001). Moreover, the VEGF levels were negatively correlated with oxygen saturation (p = 0.03) and positively correlated with hemoglobin (p = 0.004) in CHD patients aged between 3 months and 10 years. Although the physiologic elevation of VEGF in the neonatal period decreases rapidly if oxygen saturation is normal, VEGF elevations persist if systemic hypoxia is present.

Abstract
The rats treated with a single i.p. injection of diethylnitrosoamine (DEN) and percial hepatectomy were fed for 11 weeks with a high fat diet mixed with 10% lard, eicosapentaenoic-acid-rich oil (EPA-oil) or arachidonic-acid-rich oil (AA-oil) and the emergence of glutathione S-transferase placental form (GST-P) in the liver was evaluated. There were no significant differences in the serum aminotransferase activities. The molar ratio of n-6 and n-3 fatty acid in the liver phospholipids was significantly low in the EPA-oil group compared with the other groups. In the EPA-oil group, the area percent and the unit area of GST-P positive foci were significantly smaller than the other groups. In the AA-oil group, no significant differences were recognized in the quantitative values for GST-P positive foci compared with the control and lard groups. In conclusion, a hepatic neoplasmic lesion induced by DEN was suppressed with EPA-rich fish oil, and arachidonic-acid-rich oil showed no effect of suppression or acceleration.

Abstract
Immune and inflammatory systems are controlled by multiple cytokines, including ILs and INFs. These cytokines exert their biological functions through Janus tyrosine kinases and STAT transcription factors. One such cytokine, IL-6, has been proposed to contribute to the development of rheumatoid arthritis (RA). We found that STAT3 was strongly tyrosine phosphorylated in synovial tissue of RA patients, but not those with osteoarthritis. Blockade of the IL-6-gp130-JAK-STAT3-signaling pathway might therefore be beneficial in the treatment of RA. We show here that the mRNA for the endogenous cytokine signaling repressor CIS3/SOCS3 is abundantly expressed in RA patients. To determine whether CIS3 is effective in treating experimental arthritis, a recombinant adenovirus carrying the CIS3 cDNA was injected periarticularly into the ankle joints of mice with antigen-induced arthritis or collagen-induced arthritis (CIA). Periarticular injection of CIS3 adenovirus drastically reduced the severity of arthritis and joint swelling compared with control groups. CIS3 was more effective than a dominant-negative form of STAT3 in the CIA model. Thus, induction of CIS3 could represent a new approach for effective treatment of RA.

Abstract
PURPOSE To clarify the relationship between allodynia and the sprouting of myelinated fibers, we examined whether the administration of nerve growth factor (NGF) affected the paw withdrawal response to non-noxious mechanical stimuli and the sprouting of myelinated fibers into lamina II of the spinal dorsal horn, using a chronic constriction injury model of the sciatic nerve. METHODS Mechanical allodynia was determined as the threshold of the withdrawal response stimulated by von Frey filaments. Sprouting was examined using horseradish peroxidase conjugated to the B fragment of cholera toxin (B-HRP). NGF was continuously infused into the site of nerve injury for 14 days after nerve ligation. RESULTS With vehicle infusion, significantly increased responsiveness to mechanical stimuli was observed on postoperative days (PODs) 5, 7, and 14 after ligation, compared with before surgery, and B-HRP-positive fibers were newly localized in lamina II on PODs 7 and 14. Infusion of NGF reduced the responsiveness to mechanical stimuli on 5, 7, and 14 PODs and B-HRP-positive fibers in lamina II on PODs 7 and 14. CONCLUSION We propose that the suppression of the increased responsiveness to mechanical stimuli produced by NGF could be related to the disappearance of B-HRP-positive fibers in lamina II.

Abstract
We prepared recombinant Japanese encephalitis (JE) virus populations possessing random mutations at the envelope (E) protein region by a long PCR-based method. Neutralization-resistant mutants were selected from these populations by application of JE-specific virus neutralizing monoclonal antibody (mAb) 503, which possessed a 51,200-fold neutralization titer. We classified the mutants into three groups, each bearing two amino acid alterations at the E protein region: 52, Gln-Arg, and 136, Lys-Glu; 136, Lys-Glu, and 275, Ser-Pro; and 126, Ile-Thr, and 136, Lys-Glu, respectively. Three different genetically engineered variants, each bearing a single mutation, 126, Ile-Thr; 136, Lys-Glu; and 275, Ser-Pro, respectively, showed partial but not complete recovery of reactivity to mAb 503. Our results indicate that the amino acid substitutions at amino acid positions 52, 126, 136, and 275 altered the structure of the neutralization epitope for mAb 503 on the E protein. All these mutations were clustered at the junction of domains I and II of the E protein and it is likely that the epitope for mAb 503 is composed of at least E(0)-e, D(0)-a, and k strands of the E protein. We also demonstrated the efficacy of the long PCR-based recombinant virus technique as a useful tool for the creation of a variety of mutants bearing random mutations at targeted areas of the virus genome.

Abstract
We investigated the role of N-methyl-D-aspartate (NMDA) receptors on non-noxious stimulus-induced pain by examining the effect of MK-801, a non-competitive NMDA receptor antagonist, on Fos-like immunoreactivity (FLI) in the spinal dorsal horn by non-noxious stimulation to rats with chronic constriction injury (CCI) of the sciatic nerve. In CCI rats that did not receive the non-noxious stimulus, FLI was significantly increased in laminae V/VI of the dorsal horn at the 7th and 14th days after surgery relative to sham rats. When CCI rats received non-noxious stimuli, rubbing the plantar of the hind paw, FLI in laminae I/II at the 14th day was significantly increased relative to CCI rats that did not receive the stimulation. In sham rats, the same stimulus significantly decreased FLI in laminae III/IV and V/VI at the 7th and 14th day. When MK-801 was administered intraperitoneally prior to non-noxious stimulation in CCI rats at the 14th day after surgery, the stimulus-induced FLI in laminae I/II in CCI rats was significantly reduced. This study indicates that NMDA receptor is involved in upregulating FLI in response to non-noxious stimulation of CCI rats.

Abstract
CD9 is an integral membrane protein associated with integrins and other membrane proteins. Mice lacking CD9 were produced by homologous recombination. Both male and female CD9-/- mice were born healthy and grew normally. However, the litter size from CD9-/- females was less than 2% of that of the wild type. In vitro fertilization experiments indicated that the cause of this infertility was due to the failure of sperm-egg fusion. When sperm were injected into oocytes with assisted microfertilization techniques, however, the fertilized eggs developed to term. These results indicate that CD9 has a crucial role in sperm-egg fusion.

Abstract
A number of developmental regulatory genes, including homeobox genes, are dynamically expressed in the mammalian cephalic ectomesenchyme during craniofacial morphogenesis. Owing to the vast amount of gene knock out experiments, functions of such genes are now being revealed in the mammalian skeletal patterning process. The murine goosecoid (Gsc) and Msx1 genes are expressed during craniofacial development and each mutant mouse displays intriguing facial abnormalities including those of middle ear ossicles, suggesting that both genes play roles in spatial programming of craniofacial regions. In order to examine whether these genes could function in concert to direct particular craniofacial morphogenesis, double knock out mice were analyzed. The phenotype of the double mutant mice was restricted to the first arch derivatives and was apparently additive of the single gene mutant mice, implying region specific genetic interactions of these homeobox genes expressed in overlapping regions of middle ear forming ectomesenchyme. Our results also suggested that the patterning of distal portions of the malleus depends on the tympanic membrane, for which normal expressions of both the genes are prerequisite.

Abstract
Sepsis and endotoxemia are involved in the development of fulminant hepatic failure, the prognosis of which is extremely poor and the mortality is high, with no available effective therapy. Here, we report that hepatocyte growth factor (HGF) exerts potent antiapoptotic effects in vivo and effectively prevents endotoxin-induced fulminant hepatic failure in mice. The animals were intraperitoneally injected three times with 120 micrograms human recombinant HGF or saline 6 hours and 30 minutes before and 3 hours after an intraperitoneal injection of lipopolysaccharide (LPS) and D-galactosamine (GalN). Administration of LPS + GalN, without HGF, rapidly led to massive hepatocyte apoptosis and severe liver injury, and all mice died of hepatic failure within 8 hours. In contrast, administration of human recombinant HGF strongly suppressed extensive progress of hepatocyte apoptosis and the liver injury induced by LPS + GalN, and 75% of the HGF-treated mice survived. Moreover, HGF strongly induced Bcl-xL expression and blocked apoptotic signal transduction upstream of CPP32 (caspase-3) in the liver, thereby leading to inhibition of massive hepatocyte apoptosis. We suggest that HGF may well have the potential to prevent fulminant hepatic failure, at least through its potent antiapoptotic action.

Abstract
Excessive activity of the Fas system in the liver is an essential event and contributor to fulminant hepatic failure, whose prognosis is extremely poor with high mortality due to lack of effective therapy. Administration of agonistic anti-Fas antibody to mice rapidly led to massive liver apoptosis and fulminant hepatic failure. In contrast, administration of human recombinant hepatocyte growth factor (HGF) abrogated Fas-induced massive liver apoptosis and the lethal hepatic failure. Addition of anti-Fas antibody to hepatocytes in primary culture induced cell death, but Fas-mediated cell death was potently suppressed by HGF. HGF strongly induced Bcl-xL expression and subsequently blocked Fas-mediated signaling pathway upstream of CPP32 in the liver. These results implicate a potential therapeutic usage of HGF for treatment of fulminant hepatic failure.

Abstract
Metastases of lung cancer are a major cause of treatment failure. To evaluate the therapeutic efficacy of gene therapy in metastatic lung cancer, we used adenoviral (ADV) mediated transfer of the herpes simplex virus thymidine kinase (HSV-tk) gene and the cytokine gene interleukin-2 (IL-2) to treat a murine model of metastatic lung cancer in the liver. Hepatic metastases were established by intrahepatic implantation of LL2 cells in syngeneic recipient mice. One week after tumor implantation, various replication defective ADV vectors were injected intratumorally. Treatment with a vector expressing the HSV-tk followed by ganciclovir administration with ADV.tk resulted in significant regression of tumor (p<0.01) as well as prolongation of survival (p<0.001). While a vector expressing mouse IL-2 ADV.IL-2 alone was ineffective, combination therapy with HSV-tk resulted in further tumor regression and improvement of animal survival (p<0.05). These results demonstrate that suicide and cytokine genes can be utilized in combination to treat metastatic lung cancer in vivo.

Abstract
In order to examine whether saliva and breast-milk are mediators of the vertical transmission of hepatitis C virus (HCV) from an HCV carrier mother, serum, saliva, and breast-milk samples from 11 HCV carrier mothers were collected at the time of delivery, and at approximately 1- to 3-months intervals for as long as 30 months postpartum. Serum was also sampled from their children. All samples were analysed for the presence of HCV RNA, using the nested polymerase chain reaction method. No HCV RNA was detected in any breast-milk samples. In saliva, HCV RNA was detected in four of the 11 mothers (36%). These four mothers also had liver function abnormalities. Hepatitis C virus RNA was not detected in any serum samples of the children, and all children had normal liver function. The children were monitored for periods from 2 to 44 months. During this period, there was no evidence of virus transmission. Breast-milk is not likely to be a source of mother-to-child transmission of HCV. Maternal saliva may harbour HCV, but it may not result in infant infection.

Abstract
Pancreatic cancer is the fifth leading cause of cancer death in the United States. Most patients have obvious metastases or locally advanced disease at the time of presentation. Surgical resection does not significantly change the clinical outcome. Combination chemotherapy induces a partial response but overall survival remains low. The aim of this study was to evaluate the feasibility of adenovirus-mediated suicide gene transduction as a therapeutic approach for pancreatic cancer. A cell line was established from a murine pancreatic ductal adenocarcinoma and intrahepatic tumors were generated by inoculation of pancreatic cancer cells into the left lateral liver lobe. Transduction efficiency was characterized in vitro and in vivo. Intrahepatic tumors were treated by intratumoral adenovirus injection in combination with intraperitoneal administration of ganciclovir. Adenovirus-mediated herpes simplex virus (HSV)-thymidine kinase (tk) gene expression followed by ganciclovir treatment was highly efficient in inhibiting pancreatic cancer cell proliferation in vitro. The proliferation of nontransduced cells was significantly reduced in the presence of HSV-tk expressing cells. Intrahepatic inoculation of pancreatic cancer cells leads to successful formation of solid adenocarcinomas in syngeneic recipients. Ad.RSV-tk injection of the tumor followed by intraperitoneal ganciclovir application caused highly significant tumor volume reduction and necrosis. These results indicate that transduction of the HSV-tk gene followed by ganciclovir is highly efficient for growth inhibition of hepatic metastases of pancreatic carcinoma.

Abstract
Interleukin-2 (IL-2) gene therapy alone and in combination with the herpes thymidine kinase gene (tk) was used to evaluate immunological responses and antitumor effects in head and neck cancer. Established floor of mouth squamous cell carcinomas in C3H/HeJ mice were directly injected with recombinant adenoviral vectors carrying both therapeutic and control genes. One week after adenoviral gene transfer, only the animals treated with combination IL-2+tk or tk alone demonstrated significant tumor regression. Residual tumors were harvested for microscopic evaluation and immunohistochemistry staining, which revealed a predominance of CD8+ lymphocytes in the tumor beds of the animals treated with IL-2. To evaluate the systemic immune effects of IL-2, animals treated with single or combination gene therapy received a second site challenge with parental tumor cells or a heterologous but syngeneic sarcoma cell line. Mice treated with combination IL-2 and tk demonstrated a protective systemic immunity specific to the parental tumor cell line, whereas no systemic immune response was evident in mice receiving IL-2 alone. In a separate experiment, a range of concentrations of the adenovirus IL-2 vector were used to treat established tumors. Even with the maximal single-dose adenovirus concentration, IL-2 alone was ineffective as a single therapy. These results support the use of adenovirus-mediated gene transfer of IL-2 as an effective immunotherapy when used adjuvantly with the tk "suicide gene".

Abstract
To explore gene therapy as a new treatment modality for hepatocellular carcinoma, a pre-clinical animal model was established by intrahepatic implantation of a mouse hepatocellular carcinoma cell line (MH134) in syngeneic recipients. The resulting hepatic tumors were treated with a recombinant adenoviral vector expressing the murine interleukin-2 (IL-2) gene, and long-term remission was achieved in 50% of the animals. The remaining animals died of malignant ascites, which also occurs in some human patients. Those animals were treated with a second dose of the recombinant adenoviral vector by direct inoculation into the peritoneal cavity, and long-term remission of the disseminated disease was achieved in 55% of the animals. Thus, a combined cure rate of greater than 75% for primary- and disseminated hepatocellular carcinoma was achieved by successive adenovirus-mediated IL-2 gene treatments. Histopathological and immunocytochemical analyses showed massive infiltration of the tumor by macrophages and T lymphocytes in IL-2 vector treated animals. The surviving animals developed systemic antitumoral cellular immunity that protected them against challenges of parental hepatoma cells implanted at distant sites. The results suggest that IL-2 gene therapy may be a strategy applicable for the treatment of both primary and metastatic hepatocellular carcinomas in man.

Abstract
Metastases of breast cancer are a major cause of treatment failure. To evaluate the therapeutic efficacy of suicide gene therapy in metastatic breast cancer, we used the herpes simplex virus thymidine kinase (HSV-tk) gene followed by ganciclovir (GCV) administration to treat breast cancer, generated by an adenocarcinoma cell line MOD in syngeneic mice. The bystander effect of HSV-tk + GCV on tumor cell killing was illustrated by demonstrating complete regression of subcutaneous tumors consisting of 90% parental tumor cells and 10% HSV-tk transformed tumor cells. To establish a model of breast cancer metastases in the liver, tumors were generated by intra-hepatic implantation of MOD cells in syngeneic animals. Two weeks after tumor cell implantation, replication defective adenoviral vectors expressing HSV-tk (ADV.tk), or beta-galactosidease (ADV. beta-Gal) were injected intratumorally, followed by buffer or GCV administration. Treatment with ADV.tk + GCV resulted in significant regression of tumor (P < .001), as assessed by computerized morphometric analysis of residual tumor. This was reflected as a significant prolongation of survival in treated animals (P < .001). These results demonstrate that ADV-mediated suicide gene therapy in vivo can be incorporated in a comprehensive treatment strategy for liver metastases of breast cancer.

Abstract
The effectiveness of combination therapy using a suicide gene and cytokine genes for the treatment of metastatic colon carcinoma in the mouse liver was investigated. Pre-established hepatic tumors treated with a recombinant adenoviral vector containing the herpes simplex virus thymidine kinase gene(tk) exhibited substantial regression, although all treated animals suffered from subsequent relapses. Although cotreatment with a mouse interleukin 2 (mIL-2)-containing adenoviral vector induced an effective antitumor immune response, the immunity waned with time, and the treated animals eventually succumbed to hepatic tumor relapse or distant metastases. In this study, mouse granulocyte macrophage colony-stimulating factor (mGM-CSF) gene was tested for its ability to further enhance and prolong the antitumoral cellular immunity. A fraction of the animals treated with tk + mIL-2 + mGM-CSF developed long-term antitumor immunity and survived for more than 4 months without recurrence. This long-term antitumor immunity could be enhanced further by subsequent "vaccination" with mIL-2-expressing parental tumor cells. The results indicate that local expression of GM-CSF in the hepatic tumors and prolonged mIL-2 expression are necessary to generate persistent antitumor immunity that is essential for the prevention of tumor recurrence and long-term animal survival.

Abstract
To assess the efficacy of an in vivo adenoviral-mediated cytotoxic gene therapy, human melanomas were established in nude mice and transduced with herpes simplex virus-thymidine kinase (tk) followed by treatment with ganciclovir (GCV). In initial experiments, adenovirus (adv) containing the beta-galactosidase reporter gene was employed to determine melanoma cell infectivity in vitro. In comparison to murine melanoma cell lines B16 and K1735-M2, human A375-SM cells exhibited up to a 10-fold greater susceptibility to adenoviral transduction, similar to the degree of infectivity found for human epidermal HaCaT cells. In addition, human A375-SM melanoma cells exhibited a greater sensitivity in vitro to the cytotoxic effects of transduction with tk-adv and treatment with GCV, which was mediated by a strong bystander effect. In vivo, intratumoral injection of relatively large human melanomas (160 mm3) with 1.2 X 109 pfu of tk-adv, followed by intraperitoneal GCV treatment (60 mg/kg twice daily) over 4 days, typically resulted in a 50% reduction in melanoma growth rate compared to mock or untreated controls. Moreover, histometrical analysis employing a rigorous computerized imaging system revealed that the residual viable tumor area in the tk-adv/GCV-treated group was only one-fifth that of solvent controls. These data show that adv is a highly efficient in vivo gene delivery system to treat experimental human melanomas. In comparison to a previous murine melanoma study, human melanomas appeared to exhibit a greater sensitivity to this cytotoxic treatment in vivo, which may hold significant promise for development of effective gene therapy modalities to treat melanoma in humans.

Abstract
The efficacy of combination therapy with a "suicide gene" and a cytokine gene to treat metastatic colon carcinoma in the liver was investigated. Tumor in the liver was generated by intrahepatic injection of a colon carcinoma cell line (MCA-26) in syngeneic BALB/c mice. Recombinant adenoviral vectors containing various control and therapeutic genes were injected directly into the solid tumors, followed by treatment with ganciclovir. While the tumors continued to grow in all animals treated with a control vector or a mouse interleukin 2 vector, those treated with a herpes simplex virus thymidine kinase vector, with or without the coadministration of the mouse interleukin 2 vector, exhibited dramatic necrosis and regression. However, only animals treated with both vectors developed an effective systemic antitumoral immunity against challenges of tumorigenic doses of parental tumor cells inoculated at distant sites. The antitumoral immunity was associated with the presence of MCA-26 tumor-specific cytolytic CD8+ T lymphocytes. The results suggest that combination suicide and cytokine gene therapy in vivo can be a powerful approach for treatment of metastatic colon carcinoma in the liver.

Abstract
We report a neonatal case of hepatic cytomegalovirus (CMV) infection associated with paucity of interlobular bile ducts. The premature infant developed severe jaundice, and died of disseminated CMV infection. The diagnosis of CMV infection was based on detection of pathognomonic inclusions in the liver and on a high titer of CMV antibody in the serum. The hepatic histologic findings in this infant included severe cholestasis, complete absence of interlobular bile ducts in the majority of the portal tracts, and CMV inclusions in the duct epithelium. Interestingly, the CMV inclusions were localized in the bile duct, but not in the parenchyma. We postulate that the paucity of interlobular bile ducts may have been a sequela of CMV infection of the liver arising from destruction of the bile ducts, leading to severe cholestasis.

Abstract
The fine structural characteristics of the bile duct in patients with alcoholic disease are described. Dark cell metamorphosis, edematous microvilli, and increased number of pinocytotic vesicles on the basal wall surface of the duct epithelium were observed. These alterations may be interpreted as evidence of disordered water metabolism, probably reflecting secretion and reabsorption hyperfunction in the duct epithelium. In addition, widened intercellular spaces in the basal half of the epithelium suggested retention of fluid following reverse pinocytosis along the lateral cell surface. Although no alterations of the duct epithelium distinct from those in patients with other liver diseases were apparent in patients with alcoholic liver disease, the basement membrane of the bile duct exhibited unusual duplication with multiple layers and occasional loop-formation in lacunae on the basal surface.

Abstract
To clarify the pathogenesis of hepatic cytomegalovirus (CMV) infection, we clinicopathologically investigated 18 infants and 10 adults with cytomegalic inclusion bodies (CIB) in the liver among a total of 75 autopsy cases with CIB in any organ of the body. CMV infection was confirmed by immunohistochemistry and in situ hybridization. When CIB were present in the liver, CMV infection also tended to be systemic. All the adults were immunocompromised patients, but diseases inducing immunodeficiency were present in only two of the infants. The severe and systemic CMV infections we found in infants might have been associated with congenital CMV infection. Histologically, hepatocyte necrosis, cholestasis, extramedullary hematopoiesis and fatty degeneration were more frequent and prominent in infants than in adults. However, inflammatory cell infiltration was only slight. In addition, the frequent association with premature birth and hypoplasia of the thymus suggested that insufficient development of immunity may result in hepatic CMV involvement in infants. CIB were most frequently observed in hepatocytes in both infants and adults, but in infants they were also frequently seen in the bile duct epithelium. These histopathological findings and the high incidence of jaundice in infant patients suggest that the bile duct is also an important site of CMV proliferation in infants, and that CMV infection may be one cause of infantile jaundice.

Abstract
A 46 year-old woman with perinephric type of xanthogranulomatous pyelonephritis is described. She had a fever and pain with a palpable mass in her right flank. The blood analysis revealed anemia, leucocytosis, gamma-globulinemia, but no hyperlipidemia. The urine analysis showed nothing abnormal, but enterobacter was present in the urine. An intravenous pyelogram demonstrated a right non-functioning kidney. The diagnosis of a perinephric abscess was made from the x-ray and ultrasonogram, and a right nephrectomy was performed. The resected kidney had a tumor-like lump covered with Gerota's fascia at the postero-lateral side of the kidney. The cut surface of the kidney revealed an area of hemorrhage, blood clotting, abscess and a brownish yellow area in the perinephric fat tissue. The calyx and pelvis were normal. Histologically, the brownish yellow area was a granuloma with foam cell infiltration. The foam cells contained lipids. The renal parenchyma showed a non-specific chronic pyelonephritis.
