Abstract
Cryptococcosis, a globally distributed mycotic disease caused by Cryptococcus neoformans or C. gattii, has been extensively studied in various domestic animals and humans. However, non-domestic species have often been overlooked in the literature, with limited attention given to their susceptibility and contribution to the epidemiology of the disease. In this study, a captive two-year-old Cape hyrax in a Japanese zoo exhibited neurological symptoms and torticollis, ultimately succumbing to the infection. Necropsy and pathological analyses, including histopathological techniques and PCR, revealed the presence of C. neoformans in the lungs, cerebrum, and internal auditory canal. While cryptococcosis has been reported in various wild animals globally, this case represents the first documented cryptococcosis in Cape hyrax.

Abstract
Introduction
Chronic inflammation has been receiving considerable attention as an emerging risk factor for cardiovascular disease. In contrast, with the aging of the population, frailty has been also attracting a great deal of attention as the residual risk for cardiovascular disease. Although inflammation and frailty exacerbate each other and have an adverse effect on many diseases, the relationship between chronic inflammation and frailty and the impact of these combination on long-term prognosis in patients with acute coronary syndrome (ACS) are not elucidated.
Purpose
The aims of this study were to determine the association between chronic inflammation and frailty and its impact on long-term cardiovascular outcomes in patients with ACS.
Methods
A total of 482 consecutive ACS patients with obstructive coronary artery disease (age 66±12 years, male 81%) were enrolled in this observational study. We evaluated patients' gait speed as a measure of frailty before discharge. C-reactive protein (CRP) levels at 1 month after discharge were also evaluated as inflammation in the chronic phase. According to commonly used criteria of the residual inflammation (CRP>0.2 mg/dL) and the definition of the European Working Group for Sarcopenia (gait speed ≤0.8 m/sec), patients were stratified by 4 subgroups: low/high CRP with slow/normal gait speed. The primary endpoint was composite outcomes of cardiovascular death, myocardial infarction and ischemic stroke.
Results
While there was no significant association between CRP levels and gait speed in all patients, a significant negative association between two variables was observed in the high CRP group (Spearman's ρ = −0.31, p=0.001). During the median follow-up of 6 years, primary endpoints have occurred in 82 patients. Overall, event-free rates differed significantly among the 4 groups, demonstrating the lowest event-free rate in the patients with high CRP and slow gait speed (p<0.0001; Figure). In the multivariate analysis, high CRP (adjusted HR 1.99, 95% CI 1.14–3.46, p=0.02) and slow gait speed (adjusted HR 1.82, 95% CI 1.09–3.04, p=0.02) were independently and significantly associated with the primary endpoint. Moreover, the patients with both high CRP and slow gait speed had a 2.6-fold higher risk of cardiovascular events compared to others (adjusted HR 2.62, 95% CI 1.36–5.05, p=0.004).
Conclusion
In the patients with ACS, CRP levels and gait speed were negatively associated in the high CRP group. Chronic inflammation and frailty were both associated with poor prognosis in ACS and in particular, the combination of these factors was strongly associated with poor prognosis.

Abstract
Abstract
Background
The early transmitral flow velocity (E) divided by the early diastolic velocity of the mitral valve annulus (e') is referred to as the “E/e' ratio,” is useful even for ST elevation acute myocardial infarction (STEMI). However, the role of late diastolic velocity (a') which reveals the atrial function for STEMI is still unclear.
Objectives
We evaluated the clinical usefulness of tissue Doppler including atrial function for a first-time STEMI by long time follow up. Furthermore, we evaluated the meaning of each parameters by performing immediately after PCI or 2 weeks later.
Methods
We treated consecutive 571 first-time STEMI patients by immediate PCI within 12 hours after onset, and we examined 270 patients at immediately after PCI (GroupA, 65 years, 250 male) and 301 patients at 2 weeks after onset (GroupB, 64 years, 243 male). We examined trans mitral flow and TDI, then defined E/e' as LV filling pressure and A/a' as left atrial function. We followed them for a long time (>5 years). The primary end point (PE) was cardiac death or re-admission for heart failure (HF).
Results
We followed the patients in Group A for 10 years, Group B for 5 years. PE occurred in 64 patients in GroupA during 10 years, and 45 patients in GroupB during 5 years. We analyzed the univariate and multivariate Cox hazard analyses and we compared e' and a', E/e' and A/a' (Table). In GroupA, a' and A/a' were the independent predictors, on the other hand neither a' nor A/a' were the predictors in GroupB. E/e' was an independent predictor both in GroupA and B.
Conclusion
TDI parameters have different meanings by the timing of echocardiography after onset of a first-time STEMI. These results demonstrated that atrial dysfunction immediately after onset of STEMI suggests the poor prognosis after STEMI.

Abstract
Abstract
Background
Balloon angioplasty, including drug-coated balloon (DCB), is an important option of percutaneous coronary interventions (PCI), even in the drug-eluting stent era. Although quantitative coronary angiography (QCA) has been frequently used to determine the optimal endpoint of balloon angioplasty, physiological assessment may add incremental prognostic values. Quantitative flow ratio (QFR) has evolved as a novel 3D QCA-based physiological index to estimate fractional flow reserve without hyperemia nor pressure guidewire, offering both anatomical and functional lesion assessments. This study aimed to characterize post-procedural anatomical and physiological indexes by QFR and to compare their prognostic impacts on long-term clinical outcomes.
Methods
This retrospective study included 98 patients with de novo (n=39) or in-stent restenosis (n=59) lesions who underwent PCI with DCB (n=69) or plain-old balloon angioplasty (POBA, n=29). All lesions were analyzed by QCA and QFR. QCA analysis measured lesion length, reference lumen diameter (RLD), minimum lumen diameter (MLD) and percent diameter stenosis (%DS) at pre- and post-procedures as anatomical indexes. QFR analysis measured post-procedural QFR of target vessel (QFR-vessel) and QFR-gradient (ΔQFR between proximal and distal segments of the lesion) as physiological indexes. Primary endpoint was target lesion revascularization (TLR) within 1-year post-procedure.
Results
Target lesion profiles were as follows: lesion length 26.3±16.6 mm, RLD 2.90±0.70 mm, MLD 0.94±0.32 mm and %DS 79.3±18.6%. At post-procedure, MLD, residual %DS, QFR-vessel and QFR-gradient of target lesions were 1.88±0.49 mm, 34.7±10.6%, 0.84±0.13 and 0.06±0.04, respectively. During 1 year post-procedure, TLR occurred in 19 (19%) patients. Patients with TLR showed smaller MLD (1.66±0.45 mm vs. 1.93±0.49 mm, p=0.028) and QFR-vessel (0.79±0.03 vs. 0.85±0.01, p=0.06), and greater residual %DS (42.7±11.3% vs. 32.8±9.5%, p=0.0002) and QFR-gradient (0.12±0.06 vs. 0.04±0.02, p<0.0001) at post-procedure compared with those without. In multivariate analysis including several clinical characteristics and anatomical indexes, QFR-gradient at post-procedure was independently associated with TLR within 1-year, demonstrating higher prognostic value compared with post-procedural MLD and residual %DS (Figure). The receiver-operating characteristics curve analysis identified the best cut-off value of QFR-gradient as 0.08 for predicting 1-year TLR after balloon angioplasty, irrespective of balloon type (DCB or POBA) (Figure 1).
Conclusions
Post-procedural QFR-gradient within the lesion was an independent and stronger predictor of subsequent TLR, compared with anatomical indexes. Further studies are warranted to investigate whether QFR guidance to optimize PCI procedure could improve clinical outcomes in patients with balloon angioplasty.

Abstract
Abstract
Objectives
Doppler echocardiography is a well-recognized technique for noninvasive evaluation; however, little is known about its efficacy in patients with rapid atrial fibrillation (AF) accompanied by acute decompensated heart failure (ADHF). The aim of this study was to explore the usefulness of serial echocardiographical assessment for rapid AF patients with ADHF.
Patients
A total of 110 ADHF patients with reduced ejection fraction (HFrEF) and rapid AF who were admitted to the CCU unit and received landiolol treatmentto decrease the heart rate (HR) to <110 bpm and change HR (ΔHR) of >20% within 24 hours were enrolled.
Interventions
Immediately after admission, the patients (n=110) received landiolol, and its dose was increased to the maximum; then, we repeatedly performed echocardiography. Among them, 39 patients were monitored using invasive right heart catheterization (RHC) simultaneously with echocardiography.
Measurements and main results
There were significant relationships between Doppler and RHC parameters through the landiolol treatment (Figure, baseline–max HR treatment). We observed for the major adverse events (MAE) during initial hospitalization, which included cardiac death, HF prolongation (required intravenous treatment at 30 days), and worsening renal function (WRF). MAE occurred in 44 patients, and logistic regression analyses showed that the mean left atrial pressure (mLAP)-Doppler (odds ratio = 1.132, 95% confidence interval [CI]: 1.05–1.23, p=0.0004) and stroke volume (SV)-Doppler (odds ratio = 0.93, 95% confidence interval [CI]: 0.89–0.97, p=0.001) at 24 hours were the significant predictors for MAE, and multivariate analysis showed that mLAP-Doppler was the strongest predictor (odds ratio = 1.16, 95% CI: 0.107–1.27, p=0.0005) (Table).
Conclusions
During the control of the rapid AF in HFrEF patients withADHF, echocardiography was useful to assess their hemodynamic condition, even at bedside.

Abstract
Abstract
Introduction
Dyslipidemia, especially an increase in the low-density lipoprotein cholesterol (LDL-C) has been established as one of the most important risk factors for atherosclerotic cardiovascular diseases. In contrast, some recent studies have shown that the low LDL-C level was associated with short-term poor prognosis in patients with cardiovascular disease, and this is so-called “cholesterol paradox”. However, there is few data evaluating the effects on long-term outcome of “cholesterol paradox” in patients with acute coronary syndrome (ACS).
Purpose
The purpose of this study was to examine whether the low LDL-C level on admission affect long-term prognosis in patients with ACS.
Methods
A total of 434 ACS patients who survived to hospital discharge were enrolled in this study. All patients were statin-naïve on admission, and were received statin therapy after hospitalization. Patients were divided into the low LDL-C (≤114 mg/dl) and high LDL-C (>114 mg/dl) groups using the first tertile of the LDL-C level on admission. The primary endpoint was composite outcomes of all-cause death, myocardial infarction, ischemic stroke, hospitalization for congestive heart failure and unplanned revascularization.
Results
During a median follow-up period of 5.5 years, primary endpoint occurred in 117 patients. Overall, event-free rates differed significantly between the low and high LDL-C groups, demonstrating the lower event-free rate in patients with the low LDL-C group (38.9% in low LDL-C group versus 20.7% in high LDL-C group, p=0.0002; Figure). Even after adjustment for age, sex, body mass index, and various classical risk factors, the low LDL-C group was significantly at higher risk for primary composite outcomes compared to the high LDL-C group (adjusted hazard ratio 1.65, 95%-confidence interval 1.10–2.49, p=0.02).
Conclusion
In patients with ACS, the low LDL-C level on admission was significantly associated with long-term worse prognosis, regardless of statin therapy at discharge. In ACS patients with low LDL-C level, it might be necessary for elucidating the residual risk for secondary adverse event to improve their prognosis.

Abstract
Abstract
Introduction
Muscle, fat and bone mass may play some roles to keep physical activity and favorable outcome in patients with cardiovascular diseases. However, there is a paucity of data regarding the effects on the prognosis of skeletal muscle, fat, and bone mass in patients with ST-segment elevation myocardial infarction (STEMI).
Purpose
Our purpose was to examine whether skeletal muscle, fat, and bone mass each affect the prognosis after STEMI.
Methods
A total of 354 male patients with STEMI were enrolled in this study. Dual-energy X-ray absorptiometry scan was performed before discharge. All patients were followed up for the primary composite outcome of all-cause death, nonfatal myocardial infarction, nonfatal ischemic stroke, hospitalization for congestive heart failure, and unplanned revascularization.
Results
During a median follow-up of 32 months, 57 patients experienced primary composite outcome. Each of skeletal muscle, fat, and bone mass were indexed by height squared (kg/m2) and divided into two groups using the cut-off value obtained from the maximum Youden index to predict the primary composite outcome. The event rate was significantly higher in patients with low appendicular skeletal muscle mass index (ASMI) (29.2% vs 11.7%, p<0.001), low fat mass index (FMI) (22.9% vs 13.3%, p=0.030), and low bone mass index (23.8% vs 11.6%, p=0.002). After adjustment for age, renal function, diabetes mellitus, infarct size, Killip classification, and body mass index, low ASMI but not FMI (p=0.150) and bone mass index (p=0.159) was independently and significantly associated with the primary composite outcome (adjusted hazard ratio 2.12, 95%-confidence interval 1.05–4.31, p=0.035).
Conclusions
Index about muscle mass rather than fat and bone mass have prognostic impact in male patients with STEMI.

Abstract
Abstract
Background
Three-dimensional (3D) speckle tracking echocardiography (STE) is a novel method for assessing cardiac function because of free form out-of-plane motion effects.
Aim
To explore the role of 3D-STE for prediction of the long term prognosis in patients with a first-time ST elevation acute myocardial infarction (STEMI).
Methods
A total of 238 patients (mean age 64.6 years) with a first-time STEMI treated with reperfusion therapy were enrolled in our study. Twenty four hours after admission, standard 2D echocardiography and 3D full volume imaging were obtained and strain parameters (GLS: global longitudinal strain, GCS: global circumferential strain) were calculated using 4D LV analysis. Infarct size was measured with single-photon emission computed tomography imaging 7 to 14 days after onset. We followed them for median 94 months (inter quartile range: 69–109 months). The primary end point was the major adverse cardiac and cerebrovascular events (MACE: cardiac death, non-fatal MI, heart failure requiring intravenous diuretics administration and stroke). The patients with persistent chronic atrial fibrillation, poor image quality, emergency bypass surgery were excluded.
Results
During follow up periods, 78 patients experienced MACE (26 cardiac death, 48 heart failure, 29 non-fatal MI, 5 stroke) and 48 patients died (22 non-cardiac death). In multivariate analysis, 3D-GLS was the strongest predictor for MACE. Kaplan-Meier Curve demonstrated that 3D-GLS >−11.4 was the independent predictor for MACE (Log-rank χ2=73.818, p<0.0001). When combined with 3D-GCS >−19.2, the patients with higher value both of 3D-GLS and 3D-GCS were extremely high risk.
The figure shows the Kaplan-Meier curve according to the 4 groups based on the cut-off values determinded by ROC curves.
Conclusions
Global strain estimated by 3D-STE immediately onset of STEMI was useful tool for the prediction of long term prognosis.

Abstract
Abstract
Background
Low muscle mass with or without fat mass is a main component of cachexia in heart failure (HF) and associated with poor prognosis. There is a paucity of data, however, regarding prognostic impact of each component of body composition (i.e., muscle, fat, and bone mass).
Purpose
We hypothesized that muscle, fat, and bone mass have different impact on prognosis in HF.
Methods
We retrospectively analyzed 418 patients admitted with a diagnosis of HF (71±13 years, 59% male, 46 and 54% with preserved/mid-range (left ventricular ejection fraction (LVEF) ≥40%) and reduced (<40%) LVEF), respectively). Dual-energy X-ray absorptiometry was performed at stable state after decongestion therapy.
Results
Mean appendicular skeletal mass index (ASMI) was 6.9±1.2 kg/m2 in men and 5.6±0.9 in women, so that 55% of patients had low muscle mass categorized by the Asian Working Group of Sarcopenia. During median follow-up of 502 days, 163 (39.0%) patients experienced primary outcome defined as death or heart failure hospitalization. Using optimal cut-off of each body component chosen on the basis of a receiver operating characteristic curve and the Youden method, we demonstrated that lower ASMI defined by the cut-off of 6.5 kg/m2 in male and 5.2 in female (adjusted hazard ratio (HR): 1.768, 95% CI: 1.210–2.581, p=0.003) and bone mass (adjusted HR: 1.498, 95% CI: 1.051–2.152, p=0.025), but not lower fat mass (p=0.34), were associated with elevated risk of primary outcome after multivariate adjustment. Kaplan-Meier curves with p value by Log-rank test were shown in figure. In subgroup analysis, negative impact of lower ASMI was significant regardless of sex and LVEF category, whereas negative impact of low bone mass was significant only in 78 female patients with reduced LVEF.

Conclusions
Indices about muscle and bone mass rather than fat mass had prognostic impact in HF. The impact of each body component may different according to sex and LVEF.

Abstract
Abstract
Introduction
Sarcopenia, characterized by the loss of skeletal muscle mass and muscle strength, has been demonstrated the importance in cardiovascular diseases including ST-segment elevation myocardial infarction (STEMI). However, there is few data comparing the effects on the prognosis of skeletal muscle mass of upper and lower extremities in STEMI patients.
Purpose
Our purpose was to examine whether skeletal muscle mass of upper and lower extremities affect the prognosis after STEMI.
Methods
A total of 432 patients with STEMI were enrolled in this study. Dual-energy X-ray absorptiometry scan was performed before discharge. Each of upper and lower extremity skeletal muscle masses was indexed by height squared (kg/m2), and divided into two groups using the first quartile value for each sex. All patients were followed up for the primary composite outcome of all-cause death, nonfatal myocardial infarction, nonfatal ischemic stroke, hospitalization for congestive heart failure, and unplanned revascularization.
Results
During a median follow-up of 32 months, 68 patients experienced primary composite outcome. The event rate was significantly higher in patients with low-lower extremity skeletal muscle mass index (LESMI) than in those with high-LESMI (24.3% vs 12.9%, log-rank p<0.001), as well as in those with low-upper extremity muscle mass index than in those with high-upper extremity muscle mass index (UESMI) (19.6% vs 14.5%, log-rank p=0.047). However, after adjustment for age, gender, renal function, diabetes mellitus, infarct size, body mass index, and body fat percentage, only low-LESMI was independently and significantly associated with the primary composite outcome (adjusted hazard ratio for LESMI 2.11, 95%-confidence interval 1.06–4.14, p=0.034, adjusted hazard ratio for UESMI 1.04, 95%-confidence interval 0.52–2.08, p=0.906,).
Conclusions
Decreased muscle mass of lower extremity, rather than upper extremity, might have prognostic impact in patients with STEMI.

Abstract
We report a 78-year-old man with a gallbladder carcinoma and biliobiliary fistula, diagnosed by percutaneous transhepatic cholangioscopic biopsy through the fistula. The impacted stones in the common hepatic duct were crushed, and then selective cholangiography under percutaneous transhepatic cholangioscopy (PTCS) revealed a biliobiliary fistula. Cholangioscopic biopsy tissues taken from the gallbladder revealed adenocarcinoma, but biopsies taken from the fistula revealed no evidence of malignancy. Further investigations indicated that the gallbladder carcinoma involved the duodenum and the distal common bile duct. A hepatopancreatoduodenectomy, including both an extended right hepatic lobectomy with resection of the caudate lobe and a pancreatoduodenectomy, was performed. Despite the patient's advanced age, he made an unremarkable postoperative recovery and was able to enjoy an active social life for 8 months after the surgery. We discuss biliobiliary fistula associated with gallbladder carcinomas and the use of hepatopancreatoduodenectomy for advanced biliary cancer in aged patients.

Abstract
Absence of the bifurcation of the portal vein is an extremely rare anomaly and the misled ligation of the portal vein would result in the lethal hepatic failure. In this paper, a resected case of hilar cholangiocarcinoma with this anomalous portal venous system is first presented. Preoperative percutaneous transhepatic portography disclosed an absence of portal bifurcation and a transversely running portal vessel from the right anterior segment to the left lateral segment. The patient underwent left hepatic lobectomy with caudate lobectomy, in which the portal trunk was successfully preserved.

Abstract
We have determined the complete cDNA coding sequence of a novel cytoskeletal protein by the degenerative primer-mediated PCR strategy. This novel gene, named as macrophin (microfilament and actin filament cross-linker protein related to plectin and dystrophin, Accession No. AB029290), appears to be a human homologue of a Drosophila gene, kakapo, and shows close similarity to plectin and dystrophin on the search of BLAST homology-computed database. Comparison of the deduced protein sequences for macrophin and kakapo revealed that they were 66% similar, and both of them have an NH2-terminal actin-binding domain, a central rod region composed of spectrin-like repeats, and COOH-terminal Gas2-related region. The predicted sequences for macrophin are 5430 amino acids in length with a calculated molecular mass of 620 kDa, which is one of the largest size idenfied in human cytoskeletal proteins. High expression of macrophin was observed in brain, heart, lung, placenta, liver, kidney, and pancreas. In pancreas, we found that macrophin was specifically expressed in acinar cells than islet cells by in situ hybridization. By using radiation hybrid panel, we have mapped the macrophin gene to the chromosome 1p31-32.

Abstract
The RET finger protein (RFP), which belongs to the B box zinc finger protein family, has a tripartite motif consisting of a Ring finger, a B box finger and a coiled-coil domain. The RET finger protein becomes oncogenic when its tripartite motif is fused with the tyrosine kinase domain of the RET protein. This study examined the RFP expression in normal and tumor tissues by immunohistochemistry. RFP was detected in the nuclei of various cells, including peripheral and central neurones, hepatocytes, adrenal chromaffin cells and male germ cells. Among them, RFP was expressed at high levels in male germ cells such as primary spermatocytes and round spermatids, and formed a perinuclear cap structure in primary spermatocytes. On the other hand, high levels of cytoplasmic expression of RFP were observed in some plasma cells as well as solitary plasmacytoma and multiple myeloma. These results suggested that different nuclear/cytoplasmic distributions of RFP might play a role in the regulation of growth or differentiation of different cell types.

Abstract
We describe a case of mucosal bile duct carcinoma with superficial spread in a 69-year-old man with gallstone pancreatitis. The patient was seen at the hospital because of abdominal pain, fever, and jaundice. Endoscopic retrograde cholangiography (ERC) demonstrated a protruding lesion in the lower third of the common bile duct (CBD) showing wall irregularity suggestive of malignancy. Percutaneous transhepatic cholangioscopy (PTCS) disclosed a papillary tumor with granular mucosa extending continuously to the middle third of the CBD. Cholangioscopic biopsy specimens taken from both the papillary tumor and surrounding granular mucosa revealed papillary adenocarcinoma. After this assessment of extent of cancer by PTCS, we performed pancreatoduodenectomy with extrahepatic bile duct resection and regional lymph node dissection. Pathology examination revealed papillary adenocarcinoma limited to the mucosal layer. The resected margin of the bile duct was free of tumor. We also reviewed 25 cases of early mucosal bile duct carcinoma described in detail in the Japanese literature, and we discuss the diagnostic advantages of PTCS.

Abstract
We investigated the levels of TGF-beta in malignant pleural effusions (MPE) caused by malignant mesothelioma (MESO) or primary lung cancer. TGF-beta levels in MPE caused by MESO were 283.9 +/- 219.2 pm (mean +/- s.d.) and were three to six times higher than those due to primary lung cancers (P < 0.01 or P < 0.05). We also evaluated TGF-beta 1- and beta 2-like activities in MPE using specific polyclonal antibodies. Although TGF-beta 1-like activity could be detected in all cases, TGF-beta 2-like activities were detected in five of seven in MESO and in a few cases with primary lung cancer. These results demonstrate that the levels of total TGF-beta and TGF-beta 2-like activity may be clinically useful to differentiate MESO from primary lung cancer. Our data also suggest that TGF-beta may help further characterize the clinical features of MESO.

Abstract
A 49-year-old woman was admitted to hospital because of productive cough and dyspnea. She had been well two months before admission, when she developed an attack of asthma. Chest roentgenogram taken on admission revealed numerous shadows of inhomogeneous density in both lungs. Laboratory findings showed leukocytosis with eosinophilia (25%), high IgE level in serum and positive RAST score to Candida albicans. A diagnosis of allergic bronchopulmonary candidiasis was made by these laboratory data and clinical course. The patient was treated successfully by oral administration of methylprednisolone and inhalation of amphotericin B, but she had a relapse of the disease on cessation of steroid medication. Inhalation of beclomethasone dipropionate and procaterol hydrochloride was commenced. Thereafter, pulmonary infiltration and clinical symptoms improved after three weeks.

Abstract
Transforming growth factor-beta (TGF-beta) is one of the cytokines which play an immunosuppressive role in an inflammatory process. To investigate the local production of TGF-beta, we evaluated the levels of TGF-beta in tuberculous pleural effusions (TBPE) and non-tuberculous benign pleural effusions (non-TBPE) by the growth inhibition assay with Mv1Lu mink lung epithelial cells. The mean level of TGF-beta in TBPE (46.1 +/- 31.5 pM; mean +/- s.d.) was higher than in non-TBPE (21.7 +/- 12.3 pM) (P < 0.05). Although the level of interferon-gamma (IFN-gamma) in TBPE measured by ELISA was significantly higher than in non-TBPE, there was no significant difference in the levels of tumour necrosis factor-alpha (TNF-alpha) measured by ELISA between these two groups. Moreover, to elucidate localization of TGF-beta in tuberculous pleurisy, immunohistochemical studies of pleura, using the rabbit polyclonal antibody Ab39 against latent TGF-beta 1 binding protein (LTBP) were performed. Results revealed that LTBP was localized in immature fibrotic areas where infiltrations of T lymphocytes and macrophages were absent. Importantly, the major sources of LTBP in these areas were thought to be mesothelial cells and fibroblasts. LTBP was not found in granulomas and mature fibrotic areas. Our data suggest that TGF-beta in tuberculous pleurisy may play important roles for regression of granulomatous inflammation and pleural fibrosis for tissue repair.

Abstract
A case of a 60-year-old Japanese woman with small cell lung cancer involving skin and stomach is reported. She was diagnosed as primary small cell lung cancer accompanied by extensive cutaneous metastases. Three months after the last chemotherapy, she complained of nausea and vomiting. Brain CT scan showed no evidence of central nervous system involvement. Upper gastrointestinal study and upper gastrointestinal fiberscopy revealed multiple metastatic gastric tumors. Skin and stomach are uncommon metastatic sites for any malignancy. Furthermore, only a few cases with gastric metastasis could be diagnosed during their lifetime.

Abstract
Serum laminin P1 was studied in patients with small cell lung cancer (SCLC), non-small cell lung cancer (NSCLC), respiratory infections, pulmonary fibrosis, and in normal subjects. The level of serum laminin P1 was elevated (greater than 1.27 U ml-1) in 58.9% of SCLC and in 11.5% of NSCLC patients. Median value in SCLC was significantly higher than that in NSCLC (P less than 0.01), respiratory infection (P less than 0.01), and in normal subjects (P less than 0.01), but not statistically different from that in pulmonary fibrosis. The levels of serum laminin P1 in SCLC were related to therapeutic response. However, no certain correlation was established between the level of laminin P1 and the clinical stage of SCLC.

Abstract
A 73-year-old male was admitted to Hyogo College of Medicine Hospital for further evaluation of chest x-ray abnormalities. Chest roentgenogram taken at admission showed right lower lobe atelectasis and bronchoscopic examination revealed an endobronchial tumor obstructing the left lower lobe bronchus. The biopsy specimen showed cribriform adenoid cystic carcinoma. The serum CA19-9 level was markedly elevated at admission, leading to immunohistochemical analysis of the biopsy specimen. As a result, in the tumor, CA19-9 was positively stained. This is probably the first reported case of adenoid cystic carcinoma of the bronchus which produces CA19-9.

Abstract
We examined the usefulness of 3 carbohydrate antigens, CA19-9, CA125, and SLX, as tumor markers in adenoid cystic carcinoma of the trachea and bronchus, immunohistochemically and clinically. CA19-9 and SLX were detected immunohistochemically in normal tracheal and bronchial glands, but CA125 was not detected. Bronchial secretions obtained from 7 patients without cancer contained high levels of these 3 carbohydrate antigens. There was positive immunohistochemical staining for CA19-9, CA125, and SLX in 5 of 9, 1 of 9, and 3 of 8 patients with tracheal or bronchial adenoid cystic carcinoma, respectively. In a case of bronchial adenoid cystic carcinoma in whom pretreatment serum CA19-9 showed a very high level, this marker changed in parallel with the clinical course. These results suggest the possibility that CA19-9 and SLX could be used as useful markers in patients with tracheal and bronchial adenoid cystic carcinoma.

Abstract
The relationship between plasma atrial natriuretic peptide (ANP) and plasma renin activity (PRA) was examined in patients with stable chronic obstructive pulmonary disease (COPD, n = 17). The plasma ANP level in patients was approximately twice that in normal subjects. A reciprocal relationship between ANP and PRA was shown in normal subjects; however, this relationship was not observed in COPD. Plasma ANP levels inversely correlated with PaO2, and tended to inversely correlate with angiotensin converting enzyme activity in serum. These results demonstrate that patients with COPD have higher plasma ANP concentration, and that ANP and PRA are not reciprocally related in stable COPD.

Abstract
To evaluate the usefulness of serum lipid-bound sialic acid (LSA) as a tumor marker in patients with lung cancer, its serum levels were determined in 85 patients with primary lung cancer, 42 patients with benign pulmonary diseases and 22 healthy controls by the method developed by Katopodis and Stock. The mean serum LSA concentration was significantly higher in the patients with primary lung cancer [32.4 +/- 16.4 (SD) mg/dl] than that in the patients with benign pulmonary diseases (22.4 +/- 12.4 mg/dl) or in healthy controls (17.2 +/- 4.5 mg/dl). The serum LSA level was elevated above the mean value plus 2 SD for the healthy controls (26.0 mg/dl) in 60% of all cases with primary lung cancer including 1 of 9 (11.1%) in stages I and II and 50 of 76 (65.8%) in stages III and IV and 35.4% of the patients with benign pulmonary diseases. No significant difference was observed in serum LSA concentration among each cell type of lung cancer. Serum carcinoembryonic antigen (CEA) was elevated (greater than 5.0 ng/ml) in 39.8% of the patients with lung cancer. As there was poor correlation between serum LSA and CEA levels, when these two markers were used in combination, 71.1% of the cases with lung cancer in this study showed elevated levels of either serum LSA or CEA, or both. Moreover, in the patients with small cell lung cancer followed up during intensive chemotherapy, serum LSA levels changed almost parallel with the clinical course. These results indicate that serum LSA may be a useful biochemical marker in lung cancer patients.

Abstract
The findings of Gallium-67 scans in eleven patients with malignant pleural mesothelioma were reviewed and compared to those of chest CT findings. All patients had an abnormal thoracic Ga-67 accumulation. Six out of 11 showed a diffuse accumulation over the entire involved hemithorax and a localized uptake was shown in 5. A marked diffuse thickening of pleura in the absence of adequate gallium accumulation was observed in one patient. Two out of 11 had a reduction of gallium uptake after having combination chemotherapy. These results suggest that a diffusely increased uptake over the entire involved hemithorax is the most characteristic finding of Ga-67 scan in malignant pleural mesothelioma, and that Ga-67 scans may be helpful as a valuable indicator of the proper therapy. However, the superiority of Ga-67 scan to thoracic CT as a means of determining the extent of disease process could not be verified.
