Abstract
Abstract
Introduction
Critical limb ischemia (CLI) is the end-stage of peripheral artery disease caused by atherosclerosis and inflammation. Despite advances in treatment of CLI, substantial number of patients with CLI suffer from severe pain, ulceration, and gangrene. Although the advent of stem cell-based therapy has opened a new avenue for the treatment of various diseases, accumulating evidence suggests current cell-based therapies are safe, but their efficacy is modest in CLI patients. Multilineage-differentiating stress enduring (Muse) cells were first reported by one of the authors and colleagues as endogenous pluripotent-like stem cells residing in the bone marrow, peripheral blood and connective tissue of many organs. Previous studies have demonstrated that systemic administration of exogenous Muse cells improves functional recovery after ischemic organ injury such as myocardial infarction. However, their therapeutic potential in CLI remains unclear.
Objective
The goal of this study is to elucidate the efficacy and safety of exogenous Muse cell transplantation with animal models of CLI.
Methods
Muse cells were isolated from human bone marrow-derived mesenchymal stem cells (MSCs) by fluorescence-activated cell sorting with anti-SSEA-3 antibody. To establish an animal model of CLI, 12–14-week-old male BALB/c mice were anesthetized and subjected to left femoral artery and vein resection. At 24 hours after establishment of hindlimb ischemia, mice were randomly divided into 5 groups and treated as follows: Group 1, intravenous injection of PBS as control group; group 2, intravenous injection of 3 × 104 SSEA3-negative MSCs (non-Muse MSCs); group 3, intravenous injection of 3 × 104 Muse cells; group 4, intramuscular injection of 3 × 104 Muse cells into ischemic limb; group 5, intramuscular injection of 2 × 105 mouse bone marrow-derived mononuclear cells (BM-MNCs) into ischemic limb (n=5 for each group). Hindlimb blood flow was evaluated by laser Doppler flowmetry for 14 days and expressed as the ratio of ischemic to non-ischemic hindlimb.
Results
We found that intramuscular injection of xenogeneic Muse cells without immunosuppression significantly improved the blood flow in the ischemic hindlimb compared to control at day 7 and 14 (0.67 vs. 0.52, p=0.0002 and 0.74 vs. 0.53, p<0.0001, respectively) similar to intramuscular injection of allogenic BM-MNCs. In addition, we also found that intravenous injection of xenogeneic Muse cells without immunosuppression significantly improved the blood flow in the ischemic hindlimb compared to control at day 7 and 14 (0.72, p<0.0001 and 0.67, p=0.004, respectively). In contrast, intravenous injection of xenogeneic non-Muse MSCs did not improve blood flow in the ischemic hindlimb.
Conclusion
Our result suggests that Muse cell-based regenerative therapy could be a novel, less invasive, cost-effective, and subsequently more effective treatment for CLI patients.

Abstract
Group A Streptococcus (GAS) is deleterious pathogenic bacteria whose interaction with blood vessels leads to life-threatening bacteremia. Although xenophagy, a special form of autophagy, eliminates invading GAS in epithelial cells, we found that GAS could survive and multiply in endothelial cells. Endothelial cells were competent in starvation-induced autophagy, but failed to form double-membrane structures surrounding GAS, an essential step in xenophagy. This deficiency stemmed from reduced recruitment of ubiquitin and several core autophagy proteins in endothelial cells, as demonstrated by the fact that it could be rescued by exogenous coating of GAS with ubiquitin. The defect was associated with reduced NO-mediated ubiquitin signaling. Therefore, we propose that the lack of efficient clearance of GAS in endothelial cells is caused by their intrinsic inability to target GAS with ubiquitin to promote autophagosome biogenesis for xenophagy.

Abstract
OBJECTIVE This open-label, randomized controlled trial investigated the effects of cilnidipine, an L/N-type calcium channel blocker (CCB), in patients with chronic kidney disease (CKD). METHODS Sixty patients with CKD and well-controlled hypertension being treated with a renin- angiotensin system (RAS) inhibitor and an L-type CCB (L-CCB) were randomly assigned either to switch from the L-CCB to cilnidipine after a 4-week observation period or to continue with L-CCB treatment. Blood pressure, heart rate and renal function were monitored for 12 months. Data were available for analysis from 50 patients: 24 from the cilnidipine group and 26 from the L-CCB group. RESULTS Blood pressure was well controlled in both groups. After 12 months, proteinuria and heart rate were significantly decreased in the cilnidipine group, but proteinuria increased and heart rate remained unchanged in the L-CCB group. There was a significant positive correlation between the percentage changes in proteinuria and heart rate. CONCLUSIONS Cilnidipine has antihypertensive effects equivalent to those of L-CCBs. In patients with CKD, proteinuria can be decreased by switching from an L-CCB to cilnidipine, thereby improving renal function.

Abstract
A 62-year-old female was admitted to our hospital for investigation of acute progressive renal insufficiency and a systemic inflammatory reaction, despite treatment with several antibiotics. Laboratory data revealed severe renal insufficiency and positive titers for the myeloperoxidase anti-neutrophil cytoplasmic and anti-glomerular basement membrane antibodies. The deterioration of her general status did not allow us to perform the renal biopsy. Although corticosteroid therapy, hemodialysis, and plasma exchange were concomitantly initiated, pulmonary hemorrhage occurred several days after admission. Mechanical ventilation support was provided and continuous hemodiafiltration was carried out, following which the respiratory failure improved immediately. However, she developed clinical depression and suicidal behavior under the intensive therapy. Therefore, plasma exchange was discontinued and corticosteroid was tapered as quickly as possible. Four months after admission, platelet transfusion and short-term mechanical ventilation support improved the pulmonary hemorrhage; however, her mental status deteriorated despite psychiatric consultation and treatment with a tranquilizer. Thereafter, severe and serious systemic infection due to various pathogens including Staphylococcus aureus, Cytomegalovirus, Pneumocystis jiroveci, Pseudomonas aeruginosa, and Bacteroides recurred, and she died from systemic invasive aspergillosis (IA). We suspected severe immunosuppression caused by various factors, such as predonisolone administration, chronic renal failure on maintenance hemodialysis, depression, and malnutrition due to chronic inflammation and granulocytopenia as a side effect of ganciclovir. When treating rapidly progressive glomerulonephritis, immunosuppressive status should be carefully monitored regarding not only the dosage of therapeutic regimen but also the mental health status and nutrition of the patient.

Abstract
Anti-glomerular basement membrane (anti-GBM)-induced glomerulonephritis involves T-helper type 1 (Th1) responses leading to rapid crescent formation. As many inflammatory and immune responses in general are affected by histamine, we examined the effects of histaminergic ligands on immune renal injury in the rat. Female Wistar-Kyoto rats were injected intraperitoneally with an antibody against the GBMs. Histaminergic ligands were then injected twice daily for 5 days after which renal function was assessed by proteinuria. Treatment with histamine led to significant dose-dependent reductions in proteinuria compared to the control antibody-injected group and markedly decreased the number of crescentic glomeruli and macrophage infiltration of the glomeruli. Furthermore, histamine significantly decreased the plasma concentration of interleukin-12, a Th1-type cytokine compared to the antibody-injected control animals. Dimaprit, an H(2)/H(4) agonist, mimicked the effects of histamine on proteinuria and crescent formation. Clozapine, an H(4) agonist, tended to mimic the effects of histamine, whereas an H(1), mepyramine, or an H(2) antagonist, ranitidine, did not reverse the protective effect of histamine. We suggest that histamine may alleviate renal injury in anti-GBM glomerulonephritis by suppressing the immune response.

Abstract
Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is a hereditary systemic arteriopathy presenting with migraines, mood disorders, focal neurologic deficits, recurrent ischemic attacks and dementia in young adults. The genesis of this disease relates to missense mutation of the Notch3 gene. We report here a newly identified CADASIL patient and discuss unique vascular lesions observed in the kidney. A 64-year-old female was admitted to our hospital for the investigation of proteinuria, hematuria and progressive neurological abnormalities. Her mother and brother died of cerebral infarction at a relatively young age despite a lack of apparent risk factors for arteriosclerosis. Over the past 4 months before admission, she had suffered from frequent transient ischemic attacks despite appropriate antiplatelet therapy. Blood examination revealed mild renal insufficiency and urinalysis revealed moderate protein excretion and dysmorphic hematuria. Magnetic resonance imaging of the brain revealed multiple infarcts and leukoencephalopathy. Histopathological analysis of the kidney revealed focal segmental mesangial proliferation, the loss and degeneration of arterial medial smooth muscle cells and arterial intimal thickening. Immunofluorescence analysis of glomeruli revealed IgA deposition in the mesangial area. Electron microscope analysis revealed electron-dense deposition also in the mesangial area. In addition, granular osmophilic material (GOM) was observed in the extraglomerular mesangial area and around the vascular smooth muscle cells. Genetic analysis of Notch3 revealed an R141C missense mutation and she was diagnosed with CADASIL complicated with IgA nephropathy. In immunohistological analysis, Notch3 stains were positive in vascular smooth muscle cells of the interlobular arteries and both afferent and efferent arterioles, and weak in the glomerular mesangial area. Antihypertensive treatment using angiotensin II receptor blocker and a low protein diet were initiated, and her urinary protein excretion decreased to 0.2 g/day. However, due to the progression of her neurological abnormalities, she became socially withdrawn. In CADASIL, GOM, abnormal accumulation of Notch3 ectodomain, is thought to induce the degeneration and loss of vascular smooth muscle cells and subsequent intimal thickening. Analysis of our cases provided that these morphological abnormalities were also observed in the CADASIL patient kidney.

Abstract
Idiopathic nodular glomerulosclerosis (ING) is characterized as diffuse nodular glomerulosclerotic lesions, closely resembling Kimmelstiel-Wilson lesions without diabetic mellitus. We report here three Japanese cases of ING and discuss the previous reports. The patients were 75-, 48- and 84-year-old males with a history of long-term hypertension. Laboratory examination revealed moderate proteinuria and mild renal dysfunction. Diabetes mellitus was excluded by repeated clinical and laboratory investigations. Renal histology revealed nodular glomerulosclerosis, and both afferent and efferent arteriolosclerosis in all patients. In electron microscopy, the glomerular basement membrane was markedly thick in all patients. A low-protein diet and potent anti-hypertensive treatment using angiotensin-converting enzyme inhibitors were initiated in all patients and urinary protein excretion significantly reduced without the progression of renal dysfunction. We reviewed 42 previously reported cases and our three cases. The analysis revealed that common clinical features of ING are being male (82.2%) of relatively advanced age (mean age 61.3 years), with hypertension (82.2%), mild renal dysfunction (mean serum creatinine 2.9 mg/dl) and moderate urinary protein excretion (mean 4.05 g/day). Common histopathological findings of ING are nodular glomerulosclerosis (100%), arterio-arteriolosclerosis (91.2 and 89.7%) and glomerular basement membrane thickening (85.7%). In conclusion, ING is one of the phenotypes of arteriosclerotic renal disease without diabetes mellitus. Severe arterio-arteriolosclerosis may contribute to the progression to glomerular nodular formation in ING. The combination of renin-angiotensin system inhibition and a low protein diet can be beneficial for the reduction of urinary protein excretion.

Abstract
A 48-year-old man was admitted to our hospital for investigation of mild renal dysfunction. A blood examination revealed mild elevation of creatinine level (1.77 mg/dl). Urinary examination revealed mild protein excretion (0.54 g/day) and microhematuria; renal biopsy revealed the focal proliferation of large mononuclear cells with mitosis in glomerular capillaries. According to immunohistochemical analysis, the intravascular lymphomatous cells stained positively with anti-leukocyte common antigen (LCA: CD45) and CD20, indicating a B lymphocyte lineage. In electron microscopy, the glomerular capillary was filled with lymphoma cells and epithelial foot process fusion was noted. Immunohistochemical analysis on adhesive molecules revealed a lack of CD11a expression on lymphoma cells, but positive CD54 expression on endothelial cells. Systemic 18F-fluorodeoxyglucose positron emission tomography (FDG-PET) revealed no abnormal uptake of isotopes. On the basis of these findings, we diagnosed intravascular diffuse large B cell lymphoma localized in the kidney. Despite treatment with rituximab and CHOP (prednisolone, doxorubicin, vincristine, cyclophosphamide) for 3 cycles at 1-month intervals, the renal dysfunction did not change. In histopathological analysis of the second biopsy, lymphoma cells disappeared, but focal segmental glomerulosclerosis and moderate interstitial fibrosis were noted. Electron microscopic findings revealed severe subendothelial edema with mesangial interposition, indicating severe endothelial damage. Epithelial foot process fusion was improved. These pathological analyses let us conclude that a lack of CD11a could be a candidate factor for prevention of the extravasation of lymphoma cells from blood vessels in our patient. We also presumed that the intraglomerular endothelial damage occurred due to chemotherapy-associated cell injury.

Abstract
BACKGROUND The signal transducer and activator of transcription 3 (STAT3) is a key signalling molecule implicated in the regulation of growth and malignant transformation. Constitutive activation of STAT3 is seen in several tumour derived cell lines, and in a wide variety of human malignancies. AIMS To examine the relation between p-STAT3 (activated form of STAT3) expression and clinicopathological factors in human colorectal adenocarcinoma and adenoma. METHODS Immunohistochemical analyses were carried out on tissues from 44 colorectal adenomas and 95 colorectal adenocarcinomas, comprising 18 intramucosal carcinomas and 77 invasive carcinomas. RESULTS Seventy seven of these 139 samples (55.4%) showed immunoreactivity for p-STAT3. Positive staining for p-STAT3 was seen in 69 of the 95 carcinomas. Only eight of the 44 adenomas showed immunopositivity for p-STAT3, resulting in a significant difference between total adenocarcinomas and adenomas (p < 0.001). Among the 95 cases of colorectal adenocarcinoma, p-STAT3 immunoreactivity was significantly correlated with the depth of tumour invasion (p < 0.05), venous invasion (p < 0.05), lymph node metastasis (p < 0.05), and increasing stages of the Dukes' classification (p < 0.01). Expression of p-STAT3 was detected by Western blot analysis in two different cultured human colorectal carcinoma cell lines and six colon carcinoma tissue samples obtained at surgery. CONCLUSION This is the first study to report a significant correlation of p-STAT3 expression with the depth of tumour invasion. These findings suggest that p-STAT3 expression is an important factor related to carcinogenesis and/or tumour invasion of colorectal adenocarcinoma.

Abstract
Intravenous fluorouracil and leucovorin is the standard adjuvant treatment for stage III colon cancer. However, oral adjuvant chemotherapy is attractive because it has low toxicity and greater convenience. We investigated the benefits of oral protein-bound polysaccharide K (PSK) with tegafur/uracil (UFT) as an adjuvant in stage II and III colorectal cancer. Patients were assigned to groups that received either 3 g PSK plus 300 mg UFT, or 300 mg UFT alone orally each day for a 2-year period following intravenous mitomycin C. Of 207 registered patients, 205 with stage II (n=123) or III (n=82) were analysed. The 5-year disease-free survival was 73.0% (95% CI 65.6-80.4%) with PSK (n=137) and 58.8% (95% CI 47.1-70.5%) in the controls (n=68) (P=0.016). Polysaccharide K reduced the recurrence by 43.6% (95% CI 4.5-66.7%) and mortality by 40.2% (95% CI -12.5 to 68.3%). The 5-year survival was 81.8% (95% CI 75.3-88.2%) in the PSK group and 72.1% (95% CI 61.4-82.7%) in the control group (P=0.056). In stage III patients, disease-free and overall survivals in patients receiving PSK were increased significantly: 60.0% (95% CI 47.1-72.9%) and 74.6% (95% CI 63.0-86.1%) in the PSK group as compared with 32.1% (95% CI 14.8-49.4%) and 46.4% (95% CI 28.0-64.9%) in the controls (P=0.002 and 0.003, respectively). Polysaccharide K prevented recurrence, particularly lung metastases (P=0.02; odds ratio 0.27; 95% CI 0.09-0.77). In the models, the presence of regional metastases (relative risk, 2.973; 95% CI 1.712-5.165; P<0.001), omission of PSK (relative risk, 2.106; 95% CI 1.221-3.633; P=0.007), and higher primary tumour (relative risk, 4.398; 95% CI 1.017-19.014; P=0.047) were each significant indicators of recurrence. Adverse effects were mild and compliance was good. Oral PSK with UFT reduced recurrence in stage II and III colorectal cancer, and increased survival in stage III.

Abstract
Abstract Behçet's disease is a multisystem inflammatory disorder with unknown etiology. It has been shown that the titer of plasma complement component 9 (C9) is a good indicator of the disease activity. Therefore, the involvement of C9 in the pathogenesis of Behçet's disease has been suggested. We report a case of Behçet's disease associated with complete C9 deficiency (C9D) carrying the homozygous nonsense mutation at Arg-95 of C9 (R95X). The patient presented the typical characteristics of Behçet's disease, such as uveitis, recurrent oral aphthae and genital ulcers, and arthritis, suggesting that C9 does not play an essential role in the pathogenesis of Behçet's disease.

Abstract
BACKGROUND/AIMS Conflicting results have been reported concerning the usefulness of radiotherapy for unresectable pancreatic cancer. We evaluated the clinical efficacy of intraoperative radiotherapy and/or external beam radiotherapy in combination with bypass surgery. METHODOLOGY Twenty-six patients with unresectable pancreatic cancer (16 in Stage II-III and 10 in Stage IV) were treated with intraoperative radiotherapy plus external beam radiotherapy (16 patients) or intraoperative radiotherapy alone (10 patients). The dose of intraoperative radiotherapy was either 25 or 30 Gy and the external beam radiotherapy dose was 31-60 Gy. The feasibility and clinical outcome were analyzed. RESULTS The median survival time for Stage II-III and Stage IV were 11.5 and 6.5 months, respectively. The difference between Stage II-III and Stage IV in survival patterns was statistically significant (P < 0.05). For Stage II-III patients, the survival curves between the groups of intraoperative radiotherapy plus external beam radiotherapy and intraoperative radiotherapy alone were not significantly different, and only performance status was a significant factor in the prognosis (P < 0.05). Gastrointestinal bleeding was noted in 8%, but did not occur in the patients treated with an external beam radiotherapy dose less than 50 Gy. Palliative radiation was successfully performed to relieve pain, jaundice and appetite-loss and to shorten the hospital stay. CONCLUSIONS The combination therapy with intraoperative radiotherapy and bypass surgery is considered to be tolerable and effective for unresectable pancreatic cancer, and also may improve the quality of life of the patients.

Abstract
From October, 1997 through July, 1998, an outbreak of aseptic meningitis due to echovirus type 30 occurred in the northern part of Kyushu area in Japan. In this outbreak, clinical and virologic observations were carried out on 157 in-patients with aseptic meningitis at our hospital. The age of the patients ranged from 1 year and 9 months to 57-year old. One hundred and twenty out of 157 cases were the children under 15 years of age, and in this age group, male/female ratio was 2:1. The largest proportion of cases occurred in the 5- to 9-year age group. The number of cases reached a peak in December, 1997, but the epidemic extended to the next summer. In 12 families, more than one person became ill (total 22 cases). Virus isolation from cerebrospinal fluid (CSF) was tried on 130 out of 157 cases. Echovirus 30 was isolated in 74 cases (58 children, 16 adults), and echovirus 18 in 9 cases from June, 1998 until the end of the study. Paired acute and convalescent sera were available from the 25 patients with negative virus isolation, and 7 out of 25 patients had a fourfold or greater rise in neutralizing antibodies. Headache, fever, vomiting, nuchal rigidity were detectable in most cases, but in this outbreak, continued severe headache was characteristic. Eye pain was experienced by 2% of the total cases. In children, gastrointestinal symptoms were noted in 12% of the cases, but were not in adult patients. The CSF cell counts ranged from 2 to 3,478 cells per cubic millimeter. Fifty-eight percent were predominantly lymphocytic, while 42% were polymorphonuclear predominant. Virus was highly isolated from the CSF when the specimens were obtained within three days after the onset of the acute illness, but in one case, virus was isolated on day 7. In a few cases, virus was isolated without pleocytosis in CSF.

Abstract
A 50-year-old female with systemic sclerosis (SSc) developed rapidly progressive renal insufficiency. Laboratory findings showed rapid elevation of serum creatinine level (3.8 mg/dl) and a high titer of perinuclear-antineutrophil cytoplasmic antibody (p-ANCA) (504 EU/ml). Renal pathology revealed crescentic glomerulonephritis (CrGN) without mucoid intimal proliferation of the interlobal arteries and fibrinoid necrosis of the afferent arterioles, Immunofluorescent micrography showed focal segmental granular deposition of IgG and C 3 in the mesangium and along the capillary loop and was in agreement with pauci-immune type. Recently, a subtype of renal involvement in SSc that is associated exclusively with normotensive renal failure and recognizable by p-ANCA is suggested. On the other hand, SSc with p-ANCA-positive glomerulonephritis as this case can be considered to be overlap syndrome of SSc and microscopic polyangitis nodosa (microscopic PN) because in microscopic PN, p-ANCA is detected at the range of 50% to 80% and renal pathology reveals necrotizing glomerulonephritis. In this point, we may describe this case as a suggestive one about p-ANCA-positive glomerulonephritis.

Abstract
Cyclooxygenase (COX) is a key enzyme in the synthesis of prostanoids. Two isoforms of this enzyme have been identified: COX-1 and COX-2. Recent studies have suggested that COX-2, but not COX-1, may play a role in colorectal tumorigenesis. In the present study, we investigated the expression of COX-2 as well as COX-1 in human hepatocellular carcinoma (HCC) tissues using immunohistochemistry and immunoblotting. Forty-four surgically resected HCC tissues with adjacent nontumorous livers (NTs), involving 17 cases of chronic viral hepatitis and 27 cases of cirrhosis, and 7 surgically resected, histologically normal liver tissues were used. The well-differentiated HCC expressed COX-2 more frequently and strongly than less-differentiated HCC or hepatocytes of NTs. Less-differentiated HCCs expressed less COX-2 than hepatocytes of NTs, which showed scattered, strong COX-2 expression. Histologically normal liver was weakly positive for COX-2. The expression of COX-1 was weaker than that of COX-2 in hepatic neoplastic and non-neoplastic parenchymal cells. An enhanced expression of COX-1 was not observed in well-differentiated HCCs. Immunoblotting also confirmed up-regulation of COX-2, but not COX-1, in well-differentiated HCCs. The present study is the first to demonstrate a high expression of COX-2 in well-differentiated HCC and a low expression in advanced HCC, in contrast to its continuous expression during colorectal carcinogenesis. These findings suggested that COX-2 may play a role in the early stages of hepatocarcinogenesis, but not in the advanced stages, and may consequently be related to HCC dedifferentiation.

Abstract
Boerhaave's syndrome (spontaneous esophageal perforation) is an uncommon clinical entity that frequently presents with an antecedent history of marked vomiting followed by chest or abdominal pain. We report a case of spontaneous rupture of the esophagus in 53-year-old male who was referred to our hospital with a chest discomfort. A chest radiogram revealed pleural effusion and pneumomediastinum. Nine hours after onset, the diagnosis of Boerhaave's syndrome become evident. She underwent operative repair and, after a prolonged stay, was discharged in relatively good condition 55 days after admission. The absence of vomiting prior to presentation is the distinguishing feature of this particular case. This is the seventh case in the English literature to our knowledge.

Abstract
Lens culinaris agglutinin-reactive fraction of alpha-fetoprotein (AFP-L3), which is a fucosylated variation of AFP, is not only sensitive and specific for localization of hepatocellular carcinoma (HCC) but also a prognostic factor for patients with HCC. The relationship between status of AFP-L3% in serum and pathological findings was studied using 48 resected HCC specimens. AFP-L3 fraction was measured by lectin-affinity blotting using an AFP Differentiation Kit L (Wako, Osaka, Japan), and was expressed as AFP-L3% (AFP-L3/total AFP x 100%). A cut-off level of 15% was used. Pathological findings of HCC such as histological grade (well, moderately and poorly differentiated HCC), vascular invasion, and Ki67 (MIB1), p53 (DO7) and alpha-catenin immunohistochemical staining were studied. According to the results of serum AFP concentrations and AFP-L3%, the 48 patients were divided into the following three groups: AFP greater than or equal to 20 ng/ml and AFP-L3 positive (group A, n = 14), AFP greater than or equal to 20 ng/ml and AFP-L3 negative (group B, n = 14) and AFP less than 20 ng/ml (group C, n = 20). Ki67 labeling index of HCC tissue in group A was 27.8 +/- 18.9%, which was significantly higher than those of group B (9.6 +/- 10.1%, p < 0.024) and group C (11.1 +/- 11.2%, p < 0.03). In group A, p53 expression was higher and alpha-catenin staining was reduced significantly compared with those of group B or C, respectively. The results of the study suggest that the proportion of AFP-L3% in serum reflects some biological features of HCC.

Abstract
This study was aimed at evaluating the tolerance to an intermittently administered oral UFT for hepatocellular carcinoma (HCC) with chronic liver disease (CLD). Ten patients who had received curative therapy for HCC with CLD (Child's classification A or B) were randomly assigned either an intermittent schedule (IS), oral administration of UFT (130 mg/m2/b.i.d.) with 2 days rest a week, or a continuous schedule (CS), consecutive administration of UFT with the same dose. On day 12, the serum concentration of 5-fluorouracil (5-FU) was measured. After 2 weeks rest, the patients were switched to the other schedule for 10 weeks and the concentration of 5-FU was measured on day 12. The median values of the area under the curve (AUC) and maximum concentration (Cmax) of 5-FU in IS and CS were 187.7 and 263.2 ng/ml/h, 57.1 and 93.0 ng/ml, respectively. Both the AUC and Cmax for IS were significantly lower than those for CS. One IS patient had tolerable diarrhea, while three of the CS patients had intolerable nausea and one had hemorrhagic gastritis. IS seemed to be a suitable measure for CLD.

Abstract
We demonstrated immunohistochemical staining of a-fetoprotein (AFP) in small hepatocellular carcinoma (HCC). Fifty-six patients with HCC less than 2 cm in diameter were studied. Twenty-five HCCs (44.6%) were positive for AFP-staining. The positive rate of AFP-staining in HCC tissue was higher in the patients with serum AFP concentration above 20 ng/ml than that of the patients with below 20 ng/ml. AFP-staining was demonstrated on the rough endoplasmic reticulum of HCC cells by immuno-electron microscopy. AFP-staining of tissue specimens obtained by fine needle biopsy is useful in the histologic diagnosis of HCC.

Abstract
Using retrospective studies, we have investigated the possibility of obtaining characteristic findings of inflammatory pseudotumor of the liver by magnetic resonance (MR) imaging. We examined 8 patients (involving 8 masses) who had been histologically diagnosed as having an inflammatory pseudotumor in the liver. The histological studies were performed on an excised specimen of 1 mass, and on aspiration needle biopsy specimens and the clinical courses of the other 7 masses. T1 weighted images (T1WI) and T2 weighted images (T2WI) were obtained on MR imaging. MR imagings were analyzed for visualized patterns, patterns of internal structure and patterns of contrast enhancement of dynamic MR imaging. The 8 masses were visualized as hypointense on T1WI and hyperintense on T2WI by MR imaging. Dynamic MR imaging revealed that 1 mass was markedly enhanced peripherally while another mass was homogeneously enhanced, and that enhancement was most marked immediately after injection of contrast medium and then gradually disappeared. Vessels were observed in 4 masses (the portal vein in 2 masses, the hepatic vein in 1 mass, and portal and hepatic veins in 1 mass), and these vessels were clearly visualized on T1WI. The MR imaging findings from the early stage of an inflammatory pseudotumor showed a pattern similar to that of hepatic tumors with rich blood flow. The portal vein or hepatic vein was found in the tumor in half the patients, suggesting that this characteristic was useful for diagnosis of an inflammatory pseudotumor in the liver.

Abstract
Between January 1993 and October 1995, 34 patients with anthracycline-resistant advanced breast cancer were treated with a combination chemoendocrine therapy of mitoxantrone (MIT), doxifluridine (5'-DFUR) and medroxyprogesterone acetate (MPA). Of 34 patients, 28 were evaluable for efficacy of this combination therapy, and 30 including 2 for whom data were incomplete were assessed for adverse drug reactions. Adriamycin (ADM) was used for pretreatment in 12 patients, 4'-epi-ADM in 6, and THP-ADM in 12. In the eligible patients, 8.0 mg/m2 MIT was administered intravenously every 4 weeks, and 600 mg MPA and 600 mg 5'-DFUR were given orally every day. The median follow-up period was 25 weeks (range 2-90 weeks). The median cumulative dose of mitoxantrone was 66 mg (range 12-121 mg). Of the 28 patients, 11 (39.3%) responded to this combination therapy. As for response in relation to predominant site of lesion, 1 of 5 soft tissue lesions (20%) and 8 of 12 bone metastases (66.7%) showed a partial response, and one complete response and one partial response (25.0%) were seen in eight lung lesions. None of three pleural lesions responded to this therapy. The median duration of response was 31 +/- weeks (range 12-82 weeks). Adverse drug reactions were controllable or tolerable. Combined chemoendocrine therapy with a low dose of MIT is a well-tolerated and moderately effective regimen for the treatment of anthracycline-resistant advanced breast cancer.

Abstract
BACKGROUND The purpose of the study was to verify whether OK-432 in combination with 5'-DFUR induced thymidine phosphorylase (TdR Pase) and cytokines in gastric cancer patients as well as in vitro. MATERIALS AND METHODS Fifty patients with invasive gastric cancer were randomly assigned, upon admission using by a closed-envelope technique, to either a group receiving 5'DFUR or OK-432 alone, to a group receiving both 5'DFUR and OK-432, or to a non- treated group up. Surgical specimens of the tumor and normal tissues were taken soon after gastrectomy to evaluate TdR Pase activity, IL-1 alpha and TNF-production. RESULTS TdR Pase activities were several times higher in tumor than in normal tissues. In normal tissues, TdR Pase activities in the 5'-DFUR + OK-432 group were significantly higher than in the OK-432 group. TdR Pase activity in tumors, however, showed no significant difference between treated group. In the 5'-DFUR + OK-432 group, the level of IL-1 alpha production in tumor was significantly higher compared to the control group. In the 5'-DFUR + OK-432 group, the level of TNF alpha production in tumor was significantly higher than in normal tissue. TNF alpha production in tumor showed no significant difference in each treated group compared to the control. There was a significant correlation between TdR Pase activity and IL-1 alpha production levels in tumor. CONCLUSIONS TdR Pase was induced by IL-1 alpha in tumor tissues of gastric cancer patients. OK-432 in combination with 5'-DFUR, however, did not induce TNF alpha and IL-1 alpha, and increase TdR Pase activity in gastric cancer tumors.

Abstract
We report a case of remitting seronegative symmetrical synovitis with pitting edema (RS3PE syndrome) associated with gastric carcinoma in an 80-year-old woman who developed polyarthritis with marked pitting edema of the dorsa of both hands and feet 7 days after fiberscopic examination of the stomach. A mass lesion was identified and histology of the biopsy specimen revealed gastric carcinoma. Polyarthritis and edema were partially relieved by an intraarticular injection of corticosteroid. Shortly after resection of the gastric carcinoma, her symptoms and signs disappeared. She has been free of symptoms for 3 yrs without medication.

Abstract
Echography was used to perform 118 consecutive measurements of the diameters of the inferior vena cava (IVC) in 28 chronic hemodialysis patients. There was a significant correlation between the percent changes in the IVC in the expiratory phase (dIVC-E) and the percent changes in body weight (dBW) (r = 0.620, p < 0.002, n = 118). The average IVC diameter in the expiratory phase before dialysis (IVC-E) was 15.3 +/- 4.6 mm and this value decreased gradually following ultrafiltration and reached an average diameter of 11.0 +/- 4.3 mm after dialysis. Three cases developed hypotension due to fluid removal. Their IVC-E value showed a rapid reduction below 11.0 mm in the early phase of hemodialysis, then maintained a plateau. The hypotension was attributed to hypovolemia due to excessive dehydration. Our results suggest that the IVC-E diameter in postdialysis would approach 11.0 +/- 4.3 mm, which could be interpreted as being close to the dry weight.

A case of liver tumors metastasized by Sigmoid colon cancer was treated with intrahepatic arterial infusion of CDDP (10 mg) and 5-FU (250 mg) via subcutaneously implanted reservoir. After 20 administrations of CDDP and 5-FU, the tumors in the right lobe of the liver disappeared, but those in the left lobe remained. Therefore left hepatectomy was carried out. Six months after the hepatectomy, a nodule recurrence was disclosed in the right lobe of the liver. With re-elevated serum CEA level, subsequent intrahepatic arterial infusion of CDDP and 5-FU the nodule size reduced with normalization of the serum CEA level.

Abstract
Twenty-eight chronic hemodialysis patients were studied, and 118 consecutive measurements of the diameter of their inferior vena cava (VCD) were performed with ultrasonography. There was a significant correlation between the percent change in VCD in the expiratory phase (delta VCD-E%) and the percent change of in body weight (delta BW%). The average VCD-E in predialysis was 10.7 +/- 3.2 mm/m2 and this value decreased gradually following ultrafiltration and reached a minimal diameter of 7.5 +/- 2.8 mm/m2 in postdialysis. Three cases developed hypotension due to fluid removal. Their VCD-E value showed a rapid reduction below 7.5 mm/m2 in the early phase of hemodialysis, then maintained a plateau. The hypotension was thought to be caused by hypovolemia due to overdehydration. We conclude that VCD-E was an effective indicator for determining the volume of fluid removed, and the dry weight was attained safely and correctly by means of undergoing ultrafiltration to keep the value of VCD-E above 7.5 +/- 2.8 mm/m2.

Abstract
A mortality study was performed based on the data of Annual of the Pathological Autopsy Cases in Japan in 1985-1989. The average life span of the RA patients, revealing 66.5 years in male and 64.6 years in female, was shorter than that of general population in Japan. Of 1,246 autopsied RA cases, the most common causes of death were infections (26.6%), respiratory diseases including interstitial lung disease (17.5%) and amyloidosis (12.5%). Amyloidosis was common among RA cases (25.2%), and it was suggested that RA was the most important underlying disorder of the secondary amyloidosis: in 1985 to 1989, 316 cases of 515 secondary amyloidosis (61.4%) were associated with RA.

Abstract
A 72-year-old woman with 5-year history of essential hypertension developed peritoneal tuberculosis. The patient's hypertension, which had been well-controlled by long-acting nifedipine, deteriorated after the administration of rifampicin, an antitubercular agent. During use of nifedipine and rifampicin, both the peak plasma concentration and the area under the curve of nifedipine decreased markedly to about 40% of those without rifampicin. The findings suggest that rifampicin may increase the elimination of nifedipine, presumably by induction of its hepatic metabolism. Nisoldipine, another calcium antagonist, also failed to lower the patient's blood pressure, when given in combination with rifampicin. Taken together, these findings indicate that more caution should be urged when calcium antagonist is prescribed along with rifampicin.

Abstract
We investigated the incidence of herpes zoster (HZ) and the immunological state to HZ in patients with rheumatoid arthritis (RA) and mixed connective tissue disease (MCTD) in comparison with systemic lupus erythematosus (SLE). HZ occurred in 6 (25%) out of 24 patients with RA and 4 (22%) out of 18 patients with MCTD. One patient had had HZ before the diagnosis of RA. On the other hand, all 4 patients with MCTD had had HZ before the diagnosis of MCTD. The patients with RA and MCTD showed normal or higher antibody titers to varicella zoster virus (VZV) than normal subjects as assayed by both complement fixation technique and neutralization test. However, the antibody levels were not very high compared to those in patients with SLE. On the other hand, only 7 (50%) of 14 patients with RA and 4 (40%) of 10 patients with MCTD showed positive skin reactions to VZV antigen, whereas all 15 normal subjects had positive reactions. Thus, cellular immunity to VZV was thought to be impaired in these diseases. In the patients who were receiving less than 10 mg/day of prednisolone, 7 (64%) of 11 had positive skin reactions in RA patients and 3 (60%) out of 5 patients with MCTD, whereas none (0%) out of 3 patients with RA and 1 (20%) out of 5 patients with MCTD who were receiving 10 mg/day or more prednisolone showed positive skin reactions. These results suggest that the high incidence of HZ in patients with RA and MCTD is probably due to an impaired cellular immunity as in the case of SLE.

Abstract
We determined the incidence of herpes zoster (HZ) in 119 patients with systemic lupus erythematosus (SLE). HZ occurred in 56 patients (47%), and 9 patients had had HZ even before SLE developed. After diagnosis of SLE, an incidence of zoster was high, 5.45 cases per 100 person-years. It was found that the susceptibility to HZ was not related to the presence of renal disorder or maximum dose of corticosteroids. The patients with SLE who had had HZ showed significantly higher antibody titers than those without a history of HZ and normal subjects as assayed by both complement fixation technique and neutralization test. On the other had, only 17 of 55 patients (31%) with SLE showed positive skin reactions to varicella zoster virus (VZV) antigen, whereas all 15 normal subjects had positive reactions. In the patients who were receiving less than 10 mg/day of prednisolone, 11 of 17 (65%) had positive skin reactions to VZV antigen, whereas only 4 of 31 (13%) patients who were receiving 10 mg/day or more prednisolone showed positive reactions. It was of interest that in 7 patients with SLE who had not received corticosteroids, only 2 (29%) patients showed positive skin reactions to VZV antigen. These results suggest that high incidence of HZ in patients with SLE is probably due to an impaired cellular immunity because of both underlying disease and corticosteroid treatment.

Abstract
We attempted treatment with low-dose aclarubicin (ACR), a new anthracycline, in a 66-year-old man with blastic transformation of essential thrombocythemia (ET). Two courses of ACR (20 mg/day x 7 days) were given intravenously. He showed a good response to this therapy without severe side effects. He has since maintained a state of prolonged remission. These observations indicate that low-dose ACR may be beneficial for management of the blastic transformation of ET.

Abstract
We report a case of renal angiomyolipoma with retroperitoneal hemorrhage treated by enucleation in a 47 year-old male. The mass in the anterior side of the left kidney, revealed by sonography and CT, was diagnosed as angiomyolipoma with a retroperitoneal hematoma caused by its spontaneous rupture. Removal of hematoma and enucleation of the tumor were performed after the diagnosis. Diagnosis and treatment of ruptured renal angiomyolipoma are discussed.

Abstract
The incidence of herpes zoster was determined in patients with systemic lupus erythematosus (SLE) and the cellular and humoral immunity to varicella zoster virus (VZV) investigated in 45 of these 92 patients. The incidence of herpes zoster was high, occurring in 40 patients (43%), though it was benign in all. Patients with SLE who had had zoster showed significantly higher antibody titres than normal subjects. On the other hand, only 13 of 43 (30%) patients with SLE showed positive delayed hypersensitivity skin reactions to VZV antigen, despite a history of infections with VZV, whereas all 15 normal subjects had positive reactions. Skin reactions to VZV correlated directly with the ratio of OKT4+ to OKT8+ T cells and inversely with the dose of corticosteroids. These results suggest that the high incidence of herpes zoster in patients with SLE is probably due to defects in cellular immunity and that normal or higher titres of antibodies to VZV will not act as a preventive against zoster. In addition, reactivation of VZV, whether symptomatic or not, seemed often to occur in patients with SLE.

Abstract
Two middle-aged women showed typical erythematous heliotrope eruption and Gottron's sign without any symptom of myositis. The patients were diagnosed as 'amyopathic dermatomyositis' because of normal serum CPK levels, normal EMG and no histological abnormality by muscle biopsy. Clinical manifestations improved by the treatment with corticosteroids. During tapering of corticosteroids, however, intersititial pneumonitis developed and rapidly progressed. The first patients was treated with methylprednisolone pulse therapy, azathiopurine and methotrexate. The second patients was treated with betamethazone, methlprednisolone pulse therapy and cyclosporin A. In spite of these extensive immunosuppressive therapies, both patients died of pulmonary insufficiency a few months after admission. In the literature there has been only several cases of amyopathic dermatomyositis and only one case with fatal rapidly progressive interstitial pneumonitis. A new approach to the treatment of this disease should be made.

Abstract
Two cases of refractory systemic lupus erythematosus (SLE) were successfully treated with intravenous immunoglobulins (IVIg). In Case 1, the immediate recovery from severe pancytopenia and the improvement of proteinuria were observed, following IVIg therapy in high doses (450 mg/kg) for 5 consecutive days. In Case 2, 3 courses of IVIg therapy (100 mg/kg) for 6 to 8 days resulted in a significant reduction of massive proteinuria. In both cases, the improvement of immunological variables was also seen.

Abstract
Nerve fibers containing immunoreactivities for tyrosine hydroxylase (TH) and neuropeptide Y (NPY), and exhibiting acetylcholinesterase (AChE) reactivity were examined by means of histochemical and immunohistochemical methods in the caudal lobe of the prostate in the monkey, Macacus fuscatus. TH-like immunoreactive nerve fibers were distributed abundantly in the interstitium where smooth muscle fiber bundles were rich and scarcely in the paraurethral region where they were rare. NPY-like immunoreactive nerve fibers, less abundant than TH-like immunoreactive nerve fibers, were observed not only in the interstitium but also around the prostatic acini. AChE-positive nerve fibers were much denser around the acini than in the interstitium. Both the NPY-like immunoreactive and the AChE-positive nerve fibers showed an intimate spatial association with the epithelium of the acini. Judging from the distribution pattern of these nerve fibers, the following assumption is possible. Secretion of the prostatic gland as well as the outflow of the prostatic fluid into the urethra induced by contraction of the smooth muscle cells in the interstitium may be controlled by sympathetic adrenergic nerves, while cellular secretion of the acinar epithelium is regulated by parasympathetic cholinergic nerves. The NPY-like immunoreactive nerve fibers around the acini may be non-noradrenergic; they may regulate the cellular secretion by acting on the cholinergic nerves as well as by having a direct effect on the acinar secretory cells.

Abstract
The hepatic involvement of 57 patients with systemic lupus erythematosus (SLE) was studied with special reference to liver membrane autoantibody (LMA). Liver abnormalities were found predominantly in patients with active SLE (27/48 (56%) in active SLE v 3/20 (15%) in inactive SLE). They were, however, rather mild or moderate and tended to disappear as the disease activity of SLE decreased. In this respect the liver abnormalities observed in this study differed from those in patients with lupoid hepatitis. The incidence of LMA in active SLE (8/11 (73%] was significantly greater than that in inactive SLE (4/12 (33%)). The mean LMA index value in active SLE was 8.3, which was also greater than the 2.9 in inactive SLE. Furthermore, in active SLE the mean LMA titre was significantly higher in patients with liver abnormalities than in those without. These results suggest that LMA may be associated with the activity of SLE and may be one of the factors which cause transient liver abnormalities.

Abstract
The pathogenesis of avascular necrosis of bone (ANB) was investigated in 111 patients with systemic lupus erythematosus (SLE) (24 with ANB, 87 without ANB); patients' ages, corticosteroid treatment, clinical and laboratory features associated with SLE, and haemostatic profiles were all taken into account. The mean ages of patients with and without ANB at the time of diagnosis of SLE was 24.1 and 31.2 years respectively. The mean maximal daily dose of prednisolone in the group with ANB was 50.8 mg, which was significantly higher than the dose (41.8 mg) in the group without ANB. Disease features of SLE, such as Raynaud's phenomenon, hyperlipidaemia, nephrotic syndrome, hypertension, and disease activity, were not found to be related to ANB. The percentage of patients who had lupus anticoagulant as well as a shorter activated partial thromboplastin time was greater in those with ANB than in those without. Multiple factors may be involved in the pathogenesis of ANB in SLE, and it is suggested that haemostatic abnormalities, which could be influenced by corticosteroids and young ages, play some part in the development of ANB.

Abstract
To examine the mechanism of induction of differentiation in the human malignant T-lymphoblastic cell line, MOLT-3, by 12-O-tetradecanoylphorbol-13-acetate (TPA), the role of receptors for phorbol esters was investigated. Binding of [20-3H]-phorbol-12,13-dibutyrate to TPA-resistant subclones derived from MOLT-3 was less than 50% of that of the parental MOLT-3. Scatchard analysis showed that the concentration of phorbol ester receptors in a TPA-resistant subclone was about 50% of that in the parental MOLT-3, but affinities of binding were similar, indicating that more than a certain number of phorbol ester receptors is required to induce differentiation by TPA in this human T cell line.
