Abstract
PURPOSE To identify longitudinal changes in life-space mobility and the factors influencing it among chronic, stable post-stroke patients. MATERIALS AND METHODS This prospective study included Japanese post-stroke patients who received day-care rehabilitation services and could undergo three life-space mobility assessments (at baseline, 12, and 24 months) for over 2 years, using the Life-Space Assessment (LSA) tool. Physical function, cognitive function, and activities of daily living were assessed by self-selected comfortable gait speed, Mini-Mental State Examination (MMSE), and Functional Independence Measure Motor subscale (FIM motor) scores, respectively, in addition to age, sex, time from onset, stroke type, and comorbidities. A multivariable linear mixed-effects model was used to examine the longitudinal changes in LSA scores and associated factors. RESULTS A total of 89 participants were enrolled. At baseline, the median age was 74 years, 33% were women, and median time from onset was 75 months. The LSA scores significantly declined over the two-year period. In the multivariate linear mixed-effects model adjusted for clinical characteristics, comfortable gait speed and age were significantly associated with changes in the LSA score, independent of FIM motor scores and MMSE scores. CONCLUSIONS Life-space mobility may persistently decline, and gait function may be a determinant influencing these changes in community-dwelling chronic post-stroke patients.Implications for RehabilitationLimited life-space mobility leads to less frequent participation in social activities and an increased risk of adverse health outcomes such as hospitalization.Changes in life-space mobility should be considered in the rehabilitation care plan for chronic post-stroke patients.Life-space mobility may decline persistently in stable post-stroke patients, even if they have periodically received day-care rehabilitation services.Since gait speed is a predominant factor affecting life-space mobility, regular assessment of gait function and appropriate strategies are needed to prevent deterioration of gait speed in chronic post-stroke patients.

Abstract
Purpose: To date, most research on the assessment of motivation has been exerciser-focused and has not considered how fitness professionals' motivations impact their behaviors toward exercisers during training sessions. The purpose of this study was to examine the factor structure of the Coach Motivation Questionnaire in a sample of fitness professionals (CMQ-FP) to ascertain its usefulness for this vocational grouping. Measurement invariance analysis was conducted between female and male fitness professionals, and predictive validity was tested considering need-supportive and need-thwarting behaviors as outcomes. Methods: Participants were 799 fitness professionals (female = 412) aged between 20 and 56 years (M = 28.71, SD = 3.24), who completed a multi-section survey assessing their motivation toward work and their interpersonal behaviors when engaging with exercisers. Results: The results of this research supported all three hypotheses. First, the hypothesized 6-factor measurement model showed acceptable fit to the data. Second, the factor structure of the CMQ-FP was invariant across gender (male and female fitness professionals). Third, fitness professionals' (autonomous or controlled) motivation was a valid predictor of need-supportive or need-thwarting behaviors. Conclusion: This study supported the factor structure of the CMQ-FP, presenting as a valid measure of motivation in fitness professionals. Understanding fitness professionals' perceptions of their coaching motivation can inform professional development activities to assist fitness professionals to increase understanding of what motivates these professionals and how they might be more need-supportive and less need-thwarting in their pedagogical behaviors.

Abstract
Abstract
Background
Bipolar electrograms are significantly influenced by direction of the propagating wavefront in relation to the recording bipole. Omnipolar voltage mapping may be superior to standard bipolar mapping since it obtains maximum voltage of all possible bipolar electrode orientations without the need for catheter rotation. Therefore, omnipolar maps can provide voltage maps with larger voltages as well as better defined boundaries.
Purpose
Whether omnipolar activation maps also describe better activation maps versus traditional bipolar maps during ventricular premature contraction (VPC) catheter ablation is unclear.
Methods
A high-density mapping catheter was advanced to the ventricular outflow tract and a high-resolution activation map was created. Each electrode along and across the splines of the catheter are 4mm apart. Bipoles were calculated along (MAP 2), across (MAP 3) and bidirectional (MAP 4) the splines while omnipoles (MAP 1) were derived from a right triangle clique. Within a square area, four omnipolar and two bipolar values along, across and bidirectional values were defined.
Results
Though the earliest activation site was vague by along and across maps (arrow), white color became evident by bidirectional map, and the VPC origin became distinct with omnipolar mapping. RF lesions were given via an open-irrigated ablation catheter targeting a lesion size index 5.0. The VPC was eliminated by radiofrequency ablation.
Conclusion
Omnipolar activation mapping may be more accurate than traditional bipolar mapping during ventricular premature contraction (VPC) catheter ablation.

Abstract
In 1978, the first case of hepatitis E was identified as non-A, non-B hepatitis. Hepatitis E virus (HEV) infection is believed to be one of the common causes of enterically transmitted acute hepatitis in developing countries and is rare in developed countries, except in patients with a history of travel. However, an increasing number of chronic HEV infection cases have recently been reported in developed countries. In these countries, immunosuppressed patients with HEV infection, such as organ transplant recipients, human immunodeficiency virus (HIV)-infected patients or patients with haematological malignancies, could develop chronic hepatitis E (CHE) infection. Approximately 60% of HEV infections in immunocompromised patients after solid organ transplantation evolve to CHE without antiviral treatment. Clinical manifestations of CHE are often nonspecific symptoms. Many patients with CHE infection are asymptomatic, but some have jaundice, fatigue, abdominal pain, fever and asthenia. Several extrahepatic manifestations have also been reported. Although chronic HEV infection can result in progressive severe liver failure and cirrhosis, diagnosis is often controversial because of the lack of specific diagnostic criteria. Many CHE cases are diagnosed by HEV RNA-positive serum or stool for >6 months. Immunosuppressive drugs, interferon-alpha and ribavirin have been used for treatment. Diagnostic reverse-transcription polymerase chain reaction is useful for estimating treatment efficacy. Preventive measures for HEV infection have been discussed, while systematic guidelines have not yet been reported.

Abstract
BACKGROUND Though various clinical conditions of aspergillosis can occur, depending essentially on the host's immunological status, the focus of research in North American and European countries has mainly been on invasive pulmonary aspergillosis in immunocompromised patients. There are, however, also many problems to overcome in chronic forms of aspergillosis. One of those problems is that there are no codified treatment guidelines for chronic pulmonary aspergillosis (CPA). Especially in Japan, this issue is more serious, because there are more cases with CPA due to the many aged people with past history of tuberculosis. Several clinical cases and case series have reported the usefulness of the various antifungal agents that are available. The new triazole, voriconazole, in particular, seems to be effective in the treatment of CPA. The aim of the present study is to evaluate the efficacy and safety of voriconazole in the treatment of CPA in non-immunocompromised patients. PATIENTS AND METHODS We conducted a prospective, open-label, non-comparative, multicenter study over a 2-year period. For inclusion in the study, patients with confirmed or probable CPA were recruited in 11 hospitals of the National Hospital Organization in Japan. Clinical, radiological, serological, and mycological data were collected at baseline and 12 weeks after treatment or at the end of treatment. RESULTS Among 77 patients enrolled in the study, 71 patients (mean age 65.9 years, 56 males and 15 females) were eligible for the study. All of the eligible patients presented with underlying lung diseases, including sequelae of tuberculosis (n = 35), non-tuberculous mycobacterial lung disease (n = 8), chronic obstructive pulmonary disease (COPD) (n = 8), interstitial pneumonia (n = 7), cystic lung disease (n = 4), pneumothorax (n = 3), bronchial cancer (n = 1), and others (n = 5). Voriconazole was indicated in 48 cases (68 %) as the first-line treatment for CPA and 23 patients previously received other antifungal therapies. Based on a composite of clinical, radiologic, serological, and mycologic criteria, good response was seen in 43 patients (60.6 %), no response was observed in 19 patients (26.8 %), and 4 cases (5.6 %) got worse. Five patients (7.0 %) were unassessable for efficacy. The common adverse events were visual disturbances (17 patients, 23.9 %), abnormal liver function test results (12 patients, 16.9 %), adverse psychological effects (3 patients, 4.2 %), and others (10 patients, 14.0 %). Treatment with voriconazole had to be stopped in 2 cases (2.8 %) because of serious adverse events (abnormal liver function test results). There was no association between adverse effects and trough voriconazole levels in serum. CONCLUSIONS In Japan, voriconazole provides effective therapy of CPA in non-immunocompromised patients with an acceptable level of toxicity.

Abstract
Human neutrophil antigens (HNAs) play an important role in a variety of clinical conditions including immune-mediated neutropenia, non-hemolytic transfusion reactions, and transfusion-related acute lung injury. The aim of this study was to investigate the frequency distribution of HNAs-1 to -5 among the Japanese population. We analyzed samples from 570 healthy Japanese by molecular and serologic techniques to estimate the gene frequencies of HNAs-1 to -5. DNA samples were obtained and typed for the HNA-1 (n = 523), -3 (n = 570), -4 (n = 570), and -5 (n = 508), by molecular techniques. The HNA-1 genotype was determined by using a commercial polymerase chain reaction-reverse sequence-specific oligonucleotide probes (PCR-rSSOP) kit. The HNA-3 to -5 genotypes were determined by the PCR-sequence specific primer (PCR-SSP), previously described, with a small modification. The HNA-2a phenotype was determined in 301 donors by granulocyte immunofluorescence test. In Japanese, the gene frequencies of HNA-1a, -1b, and -1c were 0.623, 0.377, and 0.000, respectively. The frequency of HNA-2a phenotype was 0.987, and the gene frequencies of HNA-3a and -3b were 0.654 and 0.346, respectively. HNA-4a and -4b were found at 1.000 and 0.000, respectively, and HNA-5a and -5b at 0.840 and 0.160, respectively. We describe, for the first time, the frequencies of all HNAs (HNA-1 to -5) among the Japanese population. This study will be helpful for the prediction of the risk of alloimmunization to HNA, especially to determine the risk of HNA alloantibody production by transfusion of HNA incompatible blood and feto-maternal incompatibility.

Abstract
Carrier cells delivering a conditionally replicating adenovirus (CRAd), which selectively replicates in tumor cells and induces tumor cell lysis, have promising potential for treatment of cancer because CRAd-loaded carrier cells evade inhibition by neutralizing anti-adenovirus (Ad) antibodies and because the carrier cells are locally retained at the injection point after local injection. A previous study by Hamada et al. demonstrated that carrier cells (CRAd-containing cell fragments derived from the carrier cells) are engulfed into the target cells, probably through a pathway independent of the primary receptor for Ad, the coxsackievirus and Ad receptor (CAR) (Mol Ther, 15: 1121-1128; 2007); however, it remains to be elucidated whether carrier cells infected with a conventional CRAd, which is composed of subgroup-C Ad serotype-5 (Ad5), mediate antitumor effects on CAR-negative cells. In order to examine whether carrier cells delivering a conventional CRAd (Carrier-F5) induce lysis of CAR-negative tumor cells, CAR-positive and CAR-negative tumor cells were incubated with Carrier-F5. Carrier-F5 mediated efficient killing of CAR-positive tumor cells; however, CAR-negative tumor cells were almost refractory to Carrier-F5. On the other hand, carrier cells loaded with a fiber-substituted CRAd containing fiber proteins of Ad serotype-35 (Ad35) (CRAd-F35), which binds to human CD46 for infection, showed efficient killing of both CAR-positive and CAR-negative tumor cells. Intra-tumoral injection of carrier cells loaded with CRAd-F35 (Carrier-F35) also resulted in efficient regression of both CAR-positive and CAR-negative tumors. These results demonstrated that the expression levels of receptors for Ad are an important factor for CRAd-loaded carrier cell-mediated cancer therapy, and that Carrier-F35 would have potential as a cancer treatment for not only CAR-positive tumors but also CAR-negative tumors.

Abstract
A 57-year-old man presented with renovascular hypertension with chronic kidney disease. 16-Multi-detector row computed tomography (MDCT) showed that the left renal artery was totally occluded and the left kidney was atrophied. The left atrophied kidney was hormonally active despite the desolation of glomerular filtration function. Percutaneous renal revascularization was successful for stenting this lesion. The renin activity in the left renal vein was decreased immediately after the procedure. He remained healthy with adequate blood pressure for three years. In this case, MDCT and renal vein renin measurement provided useful information for the decision to perform percutaneous renal revascularization.

Abstract
To investigate clinicopathological features of pyothorax-associated lymphoma (PAL), we examined medical records of 98 patients (88 males and 10 females) with PAL at a median age of 70 years (range 51-86). Seventy-nine patients had a history of artificial pneumothorax. Median interval between diagnosis and artificial pneumothorax was 43 years (range 19-64). At diagnosis, performance status (PS) was 0-1 (n=56) and 2-4 (n=42). Clinical stages were I (n=42), II (n=26), III (n=8) and IV (n=22). Pathological diagnosis comprised diffuse large-B-cell (n=78) and peripheral T-cell lymphoma (n=1). Seventeen were treated supportively. The other 81 received aggressive treatments; chemotherapy (n=52), radiotherapy (n=7), surgery (n=4) and combination (n=18). Five-year overall survival (OS) was 0.35 (95% confidence interval, 24% to 45%). Causes of deaths were PAL (n=39), respiratory failure (n=13) and others (n=12). Multivariate analysis identified prognostic factors for OS; lactate dehydrogenase levels [hazard ratio (HR)=2.36; P=0.013], sex (female versus male) (HR=0.15; P=0.01), PS (2-4 versus 0-1) (HR=2.20; P=0.02), clinical stages (III/IV versus I/II) (HR=1.95; P=0.037) and chemotherapy (HR=0.31; P=0.01). Most patients with PAL are elderly and have comorbidities, while some of them achieve durable remission with appropriate treatments. These findings prompt us to establish an optimal treatment strategy on the basis of risk stratification of individual patients.

Abstract
17143 Background: Combined modality therapy with P, C and radiation for locally advanced NSCLC is active, but its clinical data are limited in Japan. The aim of this study is to evaluate feasibility and efficacy of the therapy in a Japanese general hospital. Methods: Patients with previously untreated and locally advanced NSCLC with stage IIIA and IIIB (PS 0–1, weight loss less than 5% over past 3 months) were treated with P (40 mg/m2 on days 1,8,15, 22, 29, 36, 43), C (AUC 2 on days 1,8,15, 22, 29, 36, 43) and TRT (66 Gy/33fr over 6.5 weeks starting on day1). Results: Fifteen evaluable patients entered this study between December 2001 and March 2005. They were 12 males, 3 females, with median age 67 (57–76); 6 patients with ECOG PS 0, 9 with PS 1, 8 with stage IIIA, and 7 with IIIB. Chemotherapeutic agents were administered a median of 6 cycles (4–7) and 66 Gy of TRT done in 14 patients. It achieved 13 PRs, 1 SD and 1 PD with a response rate of 86.7%. Survival was 85.5% at 1 year, 66.0% at 2 year and 66.0% at 3 year. Eleven patients are still alive. A relapse occurred in 10 patients (66.7%) and 5 were disease-free (33.3%). The site of first relapse was distant in 5 patients, local in 3, and both local and distant in 2. Toxicity was mild: grade 3 neutropenia in 2 patients, grade 3 nausea in 1, and grade 3 esophagitis in 1. No grade 3/4 pneumonitis was observed. After completion of chemoradiotherapy scheduled, 2 patients received additional chemotherapy of PC and 1 underwent lobectomy. Conclusion: Although the number of patients is small in this study, concurrent PC and TRT for locally advanced NSCLC is feasible and highly effective for Japanese patients with good PS and minimal weight loss. No significant financial relationships to disclose.

Abstract
BACKGROUND A study was undertaken to investigate the pathogenesis of pulmonary involvement in human T lymphotropic virus type I (HTLV-I) carriers. METHODS The bronchoalveolar lavage (BAL) cell profile of 30 HTLV-I carriers (15 asymptomatic HTLV-I carriers (AHCs) and 15 symptomatic HTLV-I carriers (SHCs)) with chronic inflammatory diseases of respiratory tract and eight patients with HTLV-I associated myelopathy/tropical spastic paraparesis (HAM/TSP) was investigated. The HTLV-I proviral deoxyribonucleic acid (DNA) load in peripheral blood mononuclear cells (PBMCs) and BAL fluid from HTLV-I carriers was estimated using the quantitative polymerase chain reaction method and the correlation between the lymphocyte number in BAL fluid and the HTLV-I proviral DNA load in PBMCs and BAL fluid was examined. RESULTS The percentage of lymphocytes in BAL fluid was increased (>18%) in 11 of 30 HTLV-I carriers although there was no significant difference compared with control subjects. In HTLV-I carriers the lymphocyte number in BAL fluid correlated well with the copy number of HTLV-I proviral DNA in PBMCs. In addition, the copy number of HTLV-I proviral DNA in BAL fluid correlated well with the number of lymphocytes (both CD4+ and CD8+ cells) in BAL fluid. CONCLUSIONS These findings suggest that pulmonary lymphocytosis can occur in a subset of HTLV-I carriers without HAM/TSP and that the increased HTLV-I proviral DNA load may be implicated in the pathogenesis of pulmonary involvement in HTLV-I carriers.

Abstract
Allogeneic hematopoietic stem cell transplantation (allo-SCT) recipients are prone to infections. The incidences of mycobacterial infections after allo-SCT in several case series vary from less than 0.1-5.5%. However, no study has been published on tuberculosis following unrelated cord blood transplantation (UCBT). We retrospectively reviewed medical records of 113 adult patients with a median age of 54 years who underwent reduced-intensity UCBT (RI-UCBT) at Toranomon Hospital from March 2002 to May 2004. Mycobacterium tuberculosis infections were diagnosed in three patients (2.7%), of these two patients developed primary infection and one patient developed reactivation of latent tuberculosis. The interval between RI-UCBT and the diagnosis of tuberculosis was 34, 41 and 61 days. All the patients had disseminated disease at diagnosis. Histological examination showed the lack of granuloma in caseous necrosis. Combination antituberculous treatments showed limited efficacy, and two patients died immediately after diagnosis. M. tuberculosis caused life-threatening illness, rapidly progressing in RI-UCBT recipients. The lack of granuloma in caseous necrosis suggests the impaired T-cell function in early post transplant phase of RI-UCBT. We should consider M. tuberculosis in the differential diagnoses of fever of unknown source after RI-UCBT.

Abstract
Malignant pleural effusion develops frequently in patients with advanced lung cancer. Chemical pleurodesis is the most effective palliative treatment for these patients. The efficacy of pleurodesis using both OK-432, a preparation of Streptococcus pyogenes, and doxorubicin for 20 patients with cytology-proven malignant pleural effusion associated with lung cancer was evaluated. After complete removal of pleural effusion, OK-432 and 30 mg of doxorubicin were injected via an inserted chest tube. Treatment was terminated when the volume of daily drainage reached <200 mL. If the daily volume remained >200 mL, an additional OK-432 was administered every 3 days. In total, 16 patients (80%) revealed a complete response, two patients (10%) revealed a partial response, and no response was seen in two patients. Eighteen patients with complete or partial responses did not show subsequent reaccumulation of pleural effusion after pleurodesis. The chest tube remained in place for an average of 6.4 days, draining a mean of 2,854 mL. The main side-effects were fever and pain that were easily treated with nonsteroidal anti-inflammatory drugs. Pleurodesis using both OK-432 and doxorubicin showed high efficacy for controlling malignant pleural effusions caused by lung cancer.

Abstract
Human T lymphotrophic virus type-I (HTLV-I), a human retrovirus, infects CD4(+) lymphocytes and is thought to modify their function and a possible association with pulmonary diseases has also been suggested. However, little is known about the influence of HTLV-I on diffuse pan-bronchiolitis (DPB), a chronic inflammatory lung disease with infiltration of lymphocytes and hyperplasia of the bronchus-associated lymphoid tissue. In this study, 35 DPB patients with and without HTLV-I infection were examined. HTLV-I positive DPB patients were likely to have a larger affected area with lower FEV(1). The CD3(+)/CD25(+) lymphocyte percentage was significantly higher in the BALF of HTLV-I positive patients than in negative patients. MIP-1 alpha, IP-10 and levels in BALF were also significantly higher in HTLV-I positive patients than in negative patients. The levels of MCP-1 and IL-8 were not significantly different. In HTLV-I positive patients, the MIP-1 alpha and IP-10 levels showed a significant positive correlation with the percentage of CD3(+)/CD25 lymphocytes. BALF cells of all HTLV-I positive DPB patients showed expression of p40(tax) mRNA. We suggest that HTLV-I infection may modify DPB pathogenesis via activation of T cells. We also found that the frequency of ATL development in HTLV-I positive DPB patients was significantly higher than in all HTLV-I positive patients (OR = 8.22, 95% CI = 2.61-25.9, P < 0.01). The levels of TGF-beta in patients who developed ATL were significantly lower than in patients who did not develop ATL. Sensitivity and specificity were 80% and 85.7%, respectively (cut-off = 20 pg/ml). We also propose that these features should be taken into consideration in the treatment of DPB in HTLV-I infected individuals.

Abstract
Human T lymphotrophic virus type-I (HTLV-I), a human retrovirus, infects CD4+ lymphocytes and is thought to modify their function; a possible association with pulmonary diseases has also been suggested. However, little is known about the influence of HTLV-I on cryptogenic fibrosing alveolitis (CFA), a chronic inflammatory interstitial lung disease of unknown aetiology. In order to clarify the influence of HTLV-I infection on CFA, 72 CFA patients with and without HTLV-I infection were examined. HTLV-I positive CFA patients were likely to have larger affected areas and to show traction bronchiectasis with honeycombing change. An imbalance of matrix metalloproteinases and tissue inhibitor of metalloproteinases were also observed in the BALF of HTLV-I positive CFA patients. CD3+/CD25+ lymphocyte percentage was significantly higher in the BALF of HTLV-I positive patients compared to negative patients. MIP-1alpha, IP-10 and sICAM levels in BALF were also significantly higher in HTLV-I positive patients than in negative patients. The levels of MCP-1 and IL-8 were not significantly different. In HTLV-I positive patients, the MIP-1alpha and IP-10 levels showed a significant positive correlation with percentage of CD3+/CD25 lymphocytes. HTLV-I positive CFA patients showed a larger lesion than negative patients and exhibited increased levels of certain cytokines that correlated with activated T cells in the BALF. We suggest that HTLV-I infection may contribute to the development of CFA via activation of T cells. We also propose that these features should be taken into consideration in the treatment of CFA in HTLV-I infected individuals.

Abstract
OBJECTIVE To determine the risk factors, such as socio-economic background, quality of antenatal care and availability of family planning, responsible for high maternal mortality in Surabaya, Indonesia. METHODS The study used a case-control design. Descriptive, bivariate and multivariate analyses were carried out, comparing 59 maternal deaths and 177 women survivors in the referral hospital, from 1996 to 1999. RESULTS The risk factors for maternal mortality were: living outside of Surabaya [odds ratio (OR) = 11.7, 95% confidence interval (CI) = 5.0-29.2], unemployment (OR = 4.4, 95% CI = 1.7-13.8), unavailability of toilet facilities (OR = 2.9, 95% CI = 1.0-7.7), <4 antenatal visits (OR = 2.5, 95% CI = 1.1-5.5) and initial visit to antenatal care facilities after the fourth month of pregnancy (OR = 3.0, 95% CI = 1.3-7.0). There was no significant association between maternal mortality and the availability of family planning. CONCLUSION Low socio-economic background and the availability of antenatal care have a significant influence on maternal mortality in Surabaya, Indonesia.

Abstract
Uroguanylin is an endogenous peptide that stimulates cyclic guanosine monophosphate (cGMP) production via the activation of guanylate cyclase C (GC-C) in the intestine and kidney. A high salt diet, but not intravenous salt load, enhances the secretion of biologically active uroguanylin from the intestine and increases its concentration in plasma and urine. Our purpose is to clarify the effect of uroguanylin on renal microcirculation and the tubuloglomerular feedback (TGF) mechanism. Clearance and micropuncture experiments were performed in anesthetized rats. TGF responsiveness was assessed in superficial nephrons by measuring the changes of early proximal flow rate (EPFR) in response to orthograde loop perfusion at 40 nl/min with artificial tubular fluid (ATF). Reductions in EPFR induced by loop perfusion during intravenous infusion of uroguanylin at the rate of 10 and 50 nmol/kg/h were similar yet significantly less than that during the control period (33+/-3% and 35+/-3% vs. 47+/-3%, p<0.05). Intraluminal application of uroguanylin at 10(-7) and 10(-5) mol/l in ATF decreased EPFR by 40+/-3% and 33+/-7%, respectively, with the latter value being significantly less than the control (p<0.05). Intravenous infusion of uroguanylin did not significantly change whole kidney function. Administration of atrial natriuretic peptide (ANP), which activates GC-A and B, significantly suppressed TGF-mediated EPFR reduction either intravenously (10 nmol/kg/h) or intraluminally (10(-5) mol/l in ATF) (9+/-3% and 13+/-2% vs. 47+/-3% of the control, p<0.05). In conclusion, uroguanylin clearly suppresses TGF both through intravenous and intraluminal routes, although the effects on glomerular microcirculation and whole kidney function are far less than those of ANP.

Abstract
For 197 adults and adolescents in four villages of three small islands in the Admiralty Islands, Papua New Guinea, antimalarial antibody titers were examined using the indirect fluorescent antibody test (IFAT) and malaria parasites were detected by the microtiter plate hybridisation (MPH) method using polymerase chain reaction (PCR) technique. The parasite rate (either Plasmodium falciparum or P. vivax, or both) averaged 39.2%, varying from 31.1% to 44.8% among the four villages due to natural and artificial microenvironmental conditions related to breeding sites of mosquitoes (Anopheles farauti). The lack of flat zones owing to geomorphological formation contributed to the lowest parasite rate in the extremely small island. However, human-modified environments such as a wet-land (naturally formed but artificially reformed) and an open well played significant roles in other inter-village differences. The present findings imply significant roles of microenvironment in diversified malaria prevalence and suggest some ways of mitigation of malarial hazards.

Abstract
To evaluate the diagnostic value of a halo on computed tomography (CT) in the diagnosis of invasive pulmonary aspergillosis (IPA), we retrospectively reviewed chest CT scans and autopsy reports for patients who had been admitted to our hospitals for the treatment of hematological malignancy. Pulmonary complications were suspected in all patients and chest CT scans were taken within a month of death. We examined the association between autopsy and CT findings in 48 patients who were diagnosed as IPA (n = 17), candidosis (n = 4), zygomycosis (n = 2), infiltration of hematological malignancy (n = 12), bacterial pneumonia (n = 6), cytomegalovirus pneumonia (n = 2), pulmonary hemorrhage (n = 2), or pulmonary congestion (n = 1). Patients with IPA showed a variety of CT findings, including halo (n = 13), nodules (n = 14), granular shadows (n = 3), masses (n = 6), consolidations (n = 9), wedge-shaped consolidations (n = 1), and cavitation (n = 2). In contrast, 0, 11 and two of the 31 patients without IPA showed halo, nodules and masses, respectively. These signs were more frequently observed in IPA patients than in non-IPA patients. The CT halo, especially, seemed to be specific for IPA in hospitalized neutropenic patients with hematological malignancies who developed antibiotic-resistant fever. For CT findings other than these three signs, there were no significant differences between IPA- and non-IPA patients.

Abstract
Adenosine, one of the endogenous modulators in renal hemodynamics, has recently been shown to be a mediator of tubuloglomerular feedback (TGF). Dilazep augments endogenous adenosine actions by blocking its cellular uptake. Our purpose in the present study was to clarify the effects of dilazep on renal microcirculation and the TGF mechanism. Clearance and micropuncture experiments were performed in anesthetized rats. TGF responsiveness was assessed in superficial nephrons by measuring the changes of early proximal flow rate (EPFR) in response to loop perfusion at 0-40 nl/min with artificial tubular fluid (ATF). Under dilazep administration (0.3 mg/kg+0.3 mg/kg/h i.v.) systemic BP and GFR were decreased and renal plasma flow was unaltered; as a result, the filtration fraction tended to decrease (p=0.076). Renal vascular resistance was reduced, but not to a significant degree. The reduction in EPFR by loop perfusion was similar between controls (47 +/- 2%) and rats administered dilazep i.v. (44 +/- 5%). Intraluminal application of dilazep in ATF suppressed TGF-mediated EPFR reduction to by 46 +/- 4%, 43 +/- 7%, and 37 +/- 3% at dilazep concentrations of 10(-6), 10(-5), and 10(-4) mol/l, respectively. TGF suppression with 10(-4) mol/l dilazep was reversed by co-perfusion of 10(-5) mol/l DMPX, a selective adenosine A2 receptor antagonist. DMPX alone did not affect TGF response. In conclusion, these results indicate that systemic dilazep dilates postglomerular arterioles and does not affect TGF, and thus reduces GFR. A pharmacological concentration of dilazep applied to single nephrons clearly attenuates TGF, indicating afferent arteriolar vasodilatation. Extracellular adenosine augmented by dilazep dilates glomerular vessels at both afferent and efferent sites, probably via the activation of A2 receptors.

Abstract
Because of its location with respect to the biliary system, carcinoma of the ampulla of Vater is considered to manifest earlier in its course of development than carcinoma of the pancreas. The most common physical finding is jaundice, which occurs in 93-100% of cases [1,2]. This retrospective study describes the results of the treatment and prognosis for double primary cancers in which cancer of the ampulla of Vater was associated with malignancies in other organs in 5 patients who were diagnosed and treated at Kurume University Hospital. The patients included 5 men with an average age of 72.8 years. There were 3 synchronous double and 2 metachronous double cancer patients. Regarding prognoses of these patients, 1 patient with associated lung cancer died because of postoperative complications after pneumonectomy, 1 patient died due to carcinomatosa peritonei developing from the ampulla Vater carcinoma, and 1 patient died because of metastatic liver tumors from the ampullary carcinoma. In multiple cancers including ampulla Vater carcinoma, gastrointestinal cancers such as gastric or colon cancer occur frequently. Therefore, a careful gastrointestinal examination should be done preoperatively. We report our experience with 5 cases of ampullary carcinoma associated with malignancies in other organs and review the literature.

Abstract
Seven cases of xanthogranulomatous cholecystitis are presented, and their clinicopathological appearance is described. Three men and 4 women with xanthogranulomatous cholecystitis, aged 53-72 years old, were reviewed. Five patients had had previous attacks of acute cholecystitis lasting from 3 weeks to 6 months. Abdominal ultrasonography was performed in all patients, and computed tomography in 5 patients. Cholelithiasis and sludge were present in all patients. The gallbladder wall was thickened in all patients. On computed tomography, one patient showed no abnormal finding, and 4 patients had abnormal findings such as increased wall thickness and irregularity, and pericholecystic abnormalities. A diagnosis of gallbladder carcinoma was made preoperatively in 1 patient. During laparotomy, the gallbladders in all patients showed signs of chronic cholecystitis, and cholecystectomies were performed. Histological findings showed xanthogranulomatous cholecystitis, and 4 patients had stones in the gallbladder wall. Despite the characteristic histologic appearance of xanthogranulomatous cholecystitis, radiologic findings are nonspecific, varying from signs observed in other forms of cholecystitis to the appearance of a gallbladder neoplasm. We report here 7 cases of xanthogranulomatous cholecystitis and review the literature.

Abstract
We report a case of primary hepatocellular carcinoma (referred to as hepatocellular carcinoma below) apparently rupturing after angiography. The patient was a 62-year-old male who was admitted for the treatment of hepatocellular carcinoma. Ultrasonography (US) and computed tomography (CT) on admission showed a tumor occupying the entire left lobe of the liver and partly protruding outside the liver and a tumor embolus in the portal vein. We performed preoperative angiography, after which fever and abdominal discomfort appeared. Two days after the angiography, abdominal pain and a rapid increase in the size of the abdominal tumor were noted. US also revealed an unquestionable increase in the size of the tumor, leading to a diagnosis of intratumoral hemorrhage due to the rupture of hepatocellular carcinoma. Since child classification A, clinical stage I and ICG 11.7% indicated an adequate functional reserve of the liver, we performed an emergency operation. Laparotomy revealed that the tumor occupied almost the entire left lobe of the liver, partly protruded outside it, and was bleeding from part of its anterior surface. The volume of intra-abdominal hemorrhage was about 100 ml. A portal tumor embolus was present in the portal vein from the horizontal part to the trunk. We performed resection of the left and caudate lobes of the liver with removal of the portal tumor embolus. The resected specimens showed a hemorrhage in and around the tumor. We speculated that in a hepatocellular carcinoma that involves the surface of the liver and is complicated by tumor embolism of the portal vein, angiography could trigger the rupture of the carcinoma.

Abstract
Predicting the effect of beta-blockade therapy on the clinical outcome of patients with dilated cardiomyopathy (DCM) is difficult prior to the initiation of therapy. Myocardial fatty acid metabolism has been shown to be impaired in patients with DCM. We examined whether the extent of myocardial injury, as assessed by iodine-123 15-( p-iodophenyl)-3- R, S-methylpentadecanoic acid (BMIPP) myocardial scintigraphy, is related to the response of patients with DCM to beta-blockade therapy. Thirty-seven patients with DCM were examined using BMIPP myocardial scintigraphy before and after 6 months of treatment with metoprolol. Myocardial BMIPP uptake (%BM uptake) was estimated quantitatively as a percentage of the total injected count ratio. The left ventricular end-diastolic and end-systolic dimensions (LVDd, LVDs) and ejection fraction (LVEF) were also evaluated. The patients were divided into two groups according to their functional improvement (>10% elevation of LVEF) after 6 months of metoprolol therapy. Twenty-eight patients responded to the therapy, while nine did not. Prior to the therapy, no significant differences in LVDd, LVDs or LVEF were observed between the responders and non-responders. However, the %BM uptake was significantly lower in the non-responders than in the responders (1.0%+/-0.2% vs 2.1%+/-0.5%, P<0.001). The %BM uptake could be used to distinguish the responders from the non-responders with a sensitivity of 0.93 and a specificity of 1.00 at a threshold value of 1.4. After the metoprolol therapy, the %BM uptake improved significantly in the responders (2.5%+/-0.5%, P<0.01) but did not change in the non-responders. These results indicate that myocardial BMIPP uptake could predict the response of DCM patients to beta-blockade therapy.

Abstract
OBJECTIVE Vascular endothelial growth factor (VEGF), a cytokine associated with malignant neoplasms, is increased in a number of inflammatory and infectious disorders. But little is known about VEGF in pulmonary aspergilloma (PA). In order to clarify the predictive value of VEGF in PA, we examined serum VEGF levels in PA patients as well as expression of VEGF in the PA lesion. Patients Twenty-one patients with PA (6 with hemoptysis and the rest without hemoptysis) were investigated. METHODS In all patients, serum VEGF levels were measured by enzyme-linked immunosorbent assay. We examined the statistical correlations of serum VEGF levels with the ratio of affected area to total lung volume and VEGF with PaO2 levels. In patients with hemoptysis, we measured the serum VEGF levels three months after the initiation of therapy. We examined the expression of VEGF in the resected lung tissue of 4 patients with PA using immunohistochemistry. RESULTS Serum VEGF levels showed a significant positive correlation with the ratio of affected to total lung area and a significant negative correlation with PaO2 levels. Serum VEGF levels in patients with hemoptysis were significantly higher than in those without hemoptysis. The serum levels of VEGF in patients with hemoptysis decreased significantly in parallel with the alleviation of hemoptysis. Immunohistochemical staining demonstrated the expression of VEGF in alveolar macrophages in the lesion of PA patients. CONCLUSION We suggest that VEGF can be used as a serum marker to determine the extent of the lesion, hypoxia and hemoptysis in PA.

Abstract
We recently examined the clinicopathological and immunohistochemical features of four cases of primary hepatic carcinoma with sarcomatoid elements. Three of the four patients had associated ordinary hepatocellular carcinoma (HCC) and one had a sarcomatoid carcinoma with no apparent elements of HCC. The presenting symptoms were high fever and hypochondralgia in three patients, and right hypochondralgia without a high fever in one. The preoperative diagnoses were liver abscess in two patients, HCC in one, and cholangioma in one. Preoperative imaging showed necrotic change or abscess formation in the tumors. The sarcomatous elements showed a positive reaction to vimentin in three patients, but the ordinary HCC cells did not. Macroscopically, the tumors appeared as a single nodule with pericapsular growth. The prognoses of these patients were poor due to the early development of intrahepatic or distal metastases. We conclude that symptoms such as a high fever or hypochondralgia are characteristics of these tumors and that they may be histogenetically derived from a dedifferentiation of HCC, although no elements of HCC were found in one of our cases.

Abstract
Mitochondrial ATP synthase (F(1)F(o)-ATPase) is regulated by an intrinsic ATPase inhibitor protein. In the present study, we investigated the structure-function relationship of the yeast ATPase inhibitor by amino acid replacement. A total of 22 mutants were isolated and characterized. Five mutants (F17S, R20G, R22G, E25A, and F28S) were entirely inactive, indicating that the residues, Phe17, Arg20, Arg22, Glu25, and Phe28, are essential for the ATPase inhibitory activity of the protein. The activity of 7 mutants (A23G, R30G, R32G, Q36G, L37G, L40S, and L44G) decreased, indicating that the residues, Ala23, Arg30, Arg32, Gln36, Leu37, Leu40, and Leu44, are also involved in the activity. Three mutants, V29G, K34Q, and K41Q, retained normal activity at pH 6.5, but were less active at pH 7.2, indicating that the residues, Val29, Lys34, and Lys41, are required for the protein's action at higher pH. The effects of 6 mutants (D26A, E35V, H39N, H39R, K46Q, and K49Q) were slight or undetectable, and the residues Asp26, Glu35, His39, Lys46, and Lys49 thus appear to be dispensable. The mutant E21A retained normal ATPase inhibitory activity but lacked pH-sensitivity. Competition experiments suggested that the 5 inactivated mutants (F17S, R20G, R22G, E25A, and F28S) could still bind to the inhibitory site on F(1)F(o)-ATPase. These results show that the region from the position 17 to 28 of the yeast inhibitor is the most important for its activity and is required for the inhibition of F(1), rather than binding to the enzyme.

Abstract
We have established a rapid, simple and sensitive flow cytometric system for the detection of Plasmodium falciparum that involves lysing erythrocytes and staining parasites at the same time using a newly developed hemolysing and staining solution containing dodecyl methyl ammonium chloride and acridine orange. In this system, freed parasites of P. falciparum could be plotted separately from erythrocyte ghosts, white blood cells and platelets on the two-dimensional scattergram of forward-angle light scatter and green fluorescence by flow cytometry with an argon laser. It took only 2-3 min per sample to obtain the scattergram and analyze the data, including the time of sample preparation for flow cytometric analysis. Sample preparation with this method does not require any difficult handling procedures. The threshold of parasite detection was almost equal to that of microscopic examination for cultured P. falciparum. The results of drug-susceptibility assays using this system were also almost identical to those obtained using microscopic examination. In this system, parasites at different erythrocytic stages could be easily distinguished. This system must prove useful and practical for basic laboratory studies of P. falciparum including those requiring the differential measurement of parasites at specific erythrocytic stages.

Abstract
Smads are signal mediators for the members of the transforming growth factor-beta (TGF-beta) superfamily. Upon phosphorylation by the TGF-beta receptors, Smad3 translocates into the nucleus, recruits transcriptional coactivators and corepressors, and regulates transcription of target genes. Here, we show that Smad3 activated by TGF-beta is degraded by the ubiquitin-proteasome pathway. Smad3 interacts with a RING finger protein, ROC1, through its C-terminal MH2 domain in a ligand-dependent manner. An E3 ubiquitin ligase complex ROC1-SCF(Fbw1a) consisting of ROC1, Skp1, Cullin1, and Fbw1a (also termed betaTrCP1) induces ubiquitination of Smad3. Recruitment of a transcriptional coactivator, p300, to nuclear Smad3 facilitates the interaction with the E3 ligase complex and triggers the degradation process of Smad3. Smad3 bound to ROC1-SCF(Fbw1a) is then exported from the nucleus to the cytoplasm for proteasomal degradation. TGF-beta/Smad3 signaling is thus irreversibly terminated by the ubiquitin-proteasome pathway.

Abstract
Smads, signal transducers of the transforming growth factor-beta (TGF-beta) superfamily proteins, directly bind to DNA and regulate transcription of target genes. Smad3 binds to CAGA box, whereas Smad1 and Smad5 preferentially bind to GC-rich sequences. The beta-hairpin loop in the amino-terminal Mad homology 1 (MH1) domain is the direct DNA-binding site of Smad3; however, the amino acid sequences of the beta-hairpin loop of Smad3 and Smad1/5 are identical, suggesting that other regions may be responsible for the differential DNA binding of Smad3 and Smad1/5. To identify regions other than the beta-hairpin loop responsible for specific DNA binding of Smad3, we generated chimeras containing various regions of Smad3 and Smad1. Luciferase assays using a TGF-beta-responsive reporter (CAGA)9-MLP-Luc and gel-mobility shift assays using 3xCAGA as a probe revealed that alpha-helix 2 (H2) in the amino-terminal part of the MH1 domain plays an important role in specific DNA binding and transcriptional activation of Smad3. Luciferase assays using natural TGF-beta-responsive reporters also revealed the functional importance of H2 in the Smad3 MH1 domain in direct DNA binding. Smad3 thus binds to DNA directly through the beta-hairpin loop, and H2 supports specific DNA binding of Smad3.

Abstract
Of the 139 patients who underwent excision for invasive cancer in the pancreatic duct at Kurume University Hospital between January 1965 and December 1998, the subjects were 38 patients in whom blood vessels around the cancer were simultaneously excised. The surgical methods were pancreatoduodenectomy (PD) in 31 patients, distal pancreatectomy (DP) in 5, and total pancreatectomy (TP) in 2. The excised blood vessels were the portal vein alone in 32 patients, the artery alone in 1, and both portal vein and artery in 5. Excision of the portal vein was performed by circumcision in 25 patients and by segmentectomy in 12. The range of circumcision was 1.0-7.0 cm (mean, 3.5 +/- 1.4 cm), and the blocking time of the portal vein was 8-36 min (mean, 19.5 +/- 8.8 min). Of the 25 patients who underwent circumcision, reconstruction was performed by end-to-end anastomosis in 23 and by transplantation of the autologous vein between the ends in 2. Of the 12 patients who underwent segmentectomy, direct suture was performed in 10, and transplantation of an autologous vein patch was performed in 2. Postoperative complications occurred in 14 of the 32 patients. In 5 of the 6 patients who underwent excision of the artery, reconstruction was performed by end-to-end anastomosis in 3 and by transplantation of the autologous vein between the ends in 2. Postoperative complications did not occur in the patient who had undergone excision of the artery alone, but 4 of the 5 patients who had undergone simultaneous excision of the portal vein and artery had postoperative complications, of whom 2 died during the period of hospitalization. Three patients with pv0, pv1 or pv2 survived for more than 3 years. Because some of the patients who had undergone excision of the portal vein alone survived for a long time and this method is relatively safe, this surgery can be generally applied, but simultaneous excision of the portal vein and artery should be carefully applied because the incidences of postoperative complications and death during the period of hospitalization are high. With the development of surgical techniques and postoperative control, simultaneous excision of pancreatic cancer and the surrounding blood vessels has become safe, but this method should only be applied to patients who have the potential to recover completely.

Abstract
Pulmonary hypertension is an important factor that determines the prognosis of chronic obstructive pulmonary disease (COPD) patients. Echocardiography is a noninvasive and useful bedside method for measurement of pulmonary artery pressure. However, this method is sometimes difficult because of the overinflated lungs in COPD patients. This study attempted to estimate pulmonary hypertension in COPD patients using transcutaneous Doppler jugular vein flow velocity recording. The mean pulmonary artery pressure (MPAP) of 64 COPD patients was examined using cardiac catheterization. The right jugular vein flow velocity was measured within 24 h using transcutaneous Doppler echo, after which the ratio of diastolic flow (Df) and systemic flow (Sf) velocity was calculated. Subsequently, the statistical correlation of MPAP and the Df/Sf ratio was examined. MPAP was also measured using standard cardiac echo methods and the results were compared. The Df/Sf velocity ratio showed significant correlation with MPAP in COPD patients (r=0.844, p<0.0001). The sensitivity was 71.4%, and the specificity 95.3% (cut-off ratio= 1.0). Jugular venous Doppler echo could be performed in all patients while other cardiac echo methods could not be performed in all patients. The specificity of the methods used was higher than other cardiac echo methods. Transcutaneous jugular vein flow velocity measurement may be applicable to bedside prediction of pulmonary hypertension in chronic obstructive pulmonary disease patients.

Abstract
The effect of aggregation of amphotericin B (AmB), as well as the complex formation of AmB with cholesterol or ergosterol, was investigated in micelles and vesicles. AmB in lysophosphatidylcholine (LPC) micelles adopted a more favorable monomeric form than that in other drug formulations. At an LPC/AmB ratio of 200, AmB existed only in monomeric form. Such monomeric behavior is likely dependent upon the fluidity and size of the micelles. In LPC micelles composed of 90% monomeric AmB, AmB-ergosterol complex formation occurred with an increase in the sterol concentration, but the complex formation of AmB-cholesterol was slight. On the other hand, in LPC micelles composed of 40% monomeric AmB, the complex formation of AmB-cholesterol as well as AmB-ergosterol was extensive. These results suggest that the complex formation of AmB with both sterols is highly dependent upon the aggregated state of AmB. In addition, using monolayers, mixtures of AmB/LPC/ergosterol were became more stable with rising temperature, while the stability of mixtures of AmB/LPC/cholesterol remained unchanged, implying that complex formation of AmB with cholesterol is different from that of AmB with ergosterol.

Abstract
Diagnoses and symptoms are recorded by physicians in the chapter E of the Minimum Data Set (MDS), if they are relevant to disabilities of activities of daily living, cognition, behavior, medical treatments or risk of death. We improved the chapter so that it is suited to disease patterns in Japan in a format useful not only for nursing and ADL care but for medical treatment in our practice. In E1, diseases directly underlying the current disability states were recorded in the international classification of Disease, 9th Revision (ICD9). In 24, 670, 195, and 45 patients respectively, there were 0, 1, 2, and 3 separate recorded diseases. A Total of 63 ICD9 codes were observed, but only four codes; 290, 332, 431, and 434, were underlying diseases for 3% or more patients. These codes included mostly ischemic and degenerative disease of the brain.

Abstract
The pathogenesis of tuberculous meningitis is still unclear. Recently, vascular endothelial growth factor (VEGF) was found to be associated with inflammatory diseases and we found the increased serum level of VEGF in pulmonary tuberculosis. We hypothesized that VEGF might be associated with the pathogenesis of tuberculous meningitis and measured serum and cerebrospinal fluid (CSF) levels of VEGF in 28 patients with tuberculous meningitis and 31 non-tuberculous infectious meningitis patients (13 bacterial meningitis patients, eight fungal meningitis patients and 10 patients with viral meningitis) before therapy. We examined the CSF VEGF levels 3 months after in 12 tuberculous meningitis patients. The serum and CSF levels of VEGF were significantly higher in tuberculous meningitis than in other meningitis. The decrease in titer of CSF VEGF paralleled the clinical improvement of tuberculous meningitis. Immunohistochemical staining of autopsied brains demonstrated the presence of VEGF in the inflammatory mononuclear cells of the dense fibroconnective tissue both in the subarachnoid space and surrounding the vasculitis lesion. We found the expression of VEGF in tuberculous meningitis and think that VEGF reflects its activity.

Abstract
BACKGROUND We have previously reported that disseminated pulmonary Mycobacterium avium complex (MAC) infection is more common in human T lymphotrophic virus type I (HTLV-I) carriers than in non-carriers. However, the reason for this remains unclear. It has been shown that glycopeptidelipid (GPL), one of the lipid components of the cell envelope of MAC, is able to reduce the lymphocyte blastogenic response to mitogens. The purpose of this study was to clarify whether or not the inhibitory effect of GPL differs between HTLV-I carriers and non-carriers. METHODS Peripheral blood lymphocytes were obtained from 29 patients who had recovered from pulmonary MAC infection (10 of whom also had HTLV-I infection) and the lymphocyte counts and T cell subpopulations of the peripheral blood lymphocytes in HTLV-I carriers and non-carriers were compared. The inhibitory effect of GPL on the lymphocyte blastogenic response to phytohaemagglutinin (PHA) was tested in these 29 cases and in 15 healthy controls who had never suffered from MAC (seven of whom also had HTLV-I infection). All HTLV-I positive cases were carriers. RESULTS There was no significant difference in the numbers or subset proportions of T cells between HTLV-I carriers and non-carriers. Lymphocyte activation by PHA was significantly inhibited by GPL in MAC positive and negative HTLV-I carriers compared with MAC negative non-carriers and MAC negative healthy controls (p<0.001). CONCLUSIONS We suggest that MAC infection leads to strong inhibition of lymphocyte activation in HTLV-I carriers. This may account, in part, for the severity of pulmonary MAC infection in HTLV-I carriers.

Abstract
We report here two patients with hepatocellular carcinoma who experienced implanted metastases in the abdominal cavity after hepatectomy or microwave coagulo-necrotic therapy. Hepatic resection and microwave coagulo-necrotic therapy were successful for these tumors, and the postoperative status was satisfactory in both patients. Implanted metastases were discovered in the abdominal cavity of each of these two patients 6 months after surgery. It is necessary to look not only for the presence of liver metastasis but also for the recurrence of the tumor in the abdominal cavity during the follow-up period. Generally, surgical resection for intraabdominal implanted tumors arising from any other abdominal organs is not indicated for improving the patient's quality of life. However, resection of metastatic tumors that occur in the abdominal cavity, arising from hepatocellular carcinoma may be of value in improving patient survival.

Abstract
Interleukin-6 (IL-6) is a multifunctional cytokine that plays important roles in the immune system, hematopoiesis, and acute phase reactions. Transforming growth factor-beta (TGF-beta) also has pleiotropy including the production of acute phase proteins in hepatocytes. To elucidate the cross-talk between IL-6 and TGF-beta signaling pathways in hepatic cells, we investigated the effects of TGF-beta on IL-6-induced signal transducer and activator of transcription-3 (STAT3) activation in a human hepatoma cell line, Hep3B. IL-6-induced activation of STAT3 activity and STAT3-mediated gene expression were augmented by TGF-beta in Hep3B cells. We provide evidence that these activities were due to physical interactions between STAT3 and Sma- and MAD-related protein-3, bridged by p300. These results demonstrate a molecular mechanism of a cross-talk between STAT3 and TGF-beta signaling pathways in hepatocytes.

Abstract
Transforming growth factor-betas (TGF-betas) are potent inhibitors of cell proliferation, and disruption of components of the TGF-beta signaling pathway leads to tumorigenesis. Mutations of transmembrane receptors and Smads mediating intracellular signaling have been reported in various cancers. To identify transcriptional targets of TGF-beta, we conducted an expression profile analysis. HaCaT cells derived from human keratinocytes and highly sensitive to TGF-beta were treated with TGF-beta in the absence or presence of cycloheximide (CHX). mRNAs extracted from the HaCaT cells were used for hybridization of oligonucleotide arrays representing approximately 5600 human genes. TGF-beta increased the expression of PAI-1, junB, p21 cdk inhibitor, Smad7, betaIG-H3, and involucrin that have been reported to be up-regulated by TGF-beta, validating the usefulness of this approach. The induction of betaIG-H3 by TGF-beta was completely abolished by CHX, suggesting that the transcription of betaIG-H3 is not directly regulated by TGF-beta. Unexpectedly, we identified more genes down-regulated by TGF-beta than up-regulated ones. TGF-beta repressed the expression of epithelial specific Ets that may be involved in breast and lung tumorigenesis, which could contribute to tumor suppression by TGF-beta. Among a panel of cell cycle regulators, TGF-beta induced the expression of p21 cdk inhibitor; however, the induction of other cdk inhibitors was not significant in the present study. Taken together, the results suggest that TGF-beta may suppress tumorigenesis through positive and negative regulation of transcription.
