Abstract
A 76-year-old woman with advanced pancreatic cancer developed recurrent cholecystitis after covered self-expandable metal stent (CSEMS) placement. The cholecystitis was refractory to repeated percutaneous transhepatic gallbladder drainage (PTGBD). Cholecystography showed a patent cystic duct with right and cranial side bifurcation, which is indicative of an increased likelihood of success of endoscopic transpapillary gallbladder drainage (ETGBD). We were able to manage the cholecystitis by ETGBD without further recurrence. ETGBD is considered an effective internal drainage method for the management of acute cholecystitis after CSEMS placement, and its indication may be decided on the basis of the findings of cholecystography through the PTGBD route.

Abstract
BACKGROUND Zinc deficiency is likely to occur in chronic liver disease. The aim of this study was to determine the prevalence of zinc deficiency in different types of chronic liver disease and to identify the factors that predicted low serum zinc levels. METHODS The study was an observational single-center design. We obtained the medical records of 666 patients with chronic liver disease whose serum zinc levels had been measured. The cutoff value for zinc deficiency was a serum level < 70 µg/dL. RESULTS Serum zinc levels in the alcoholic liver disease (ALD) group were significantly lower than in the other groups (hepatitis C virus [HCV], hepatitis B virus [HBV], and other cause) (P < 0.01). The CONUT and ALBI score (r = 0.527, P < 0.01), serum zinc level and ALBI score (r = - 0.607, P < 0.01), and serum zinc level and CONUT score (r = - 0.465, P < 0.01) correlated with each other. The prevalence of zinc deficiency were 44.8%, 63.2%, 86.7%, 97.1%, and 100% in the mALBI grade 1-CONUT normal, CONUT undernutrition, and mALBI grade 2a, 2b, and 3 groups, respectively. Multivariate analysis identified ALD, CONUT score, aspartate aminotransferase, and hemoglobin as significant, independent predictors of zinc deficiency (P < 0.05). CONCLUSIONS This study identified ALD, CONUT score, aspartate aminotransferase, and hemoglobin as predictors of zinc deficiency in chronic liver disease. The rate of zinc deficiency is high even in patients classified as mALBI grade 1, especially in ALD, while caution may be required in those classified as mALBI grade 1-CONUT undernutrition.

Abstract
Objective The relationship between the prognosis and magnitude of a decrease in tumor blood flow according to estimated tumor differentiation remains unclear. This study investigated the relationship between reductions in the rate of mean computed tomography (CT) attenuation values and the clinical prognosis. Methods We evaluated 63 consecutive patients who received lenvatinib treatment for unresectable hepatocellular carcinoma (HCC). The oncological aggressiveness of the tumors was estimated using classification by dynamic CT enhancement patterns. The utility of changes in mean CT attenuation values of intra-hepatic targets during treatment to estimate the prognosis was investigated by calculating the progression-free survival (PFS) and post-progression survival (PPS). A multivariate analysis was used to identify potential confounders for the survival after progression during lenvatinib therapy. Results The rate of decrease in the mean CT attenuation value gradually increased according to the degree of deterioration in estimated tumor differentiation, and the rate of a decrease in attenuation ≥40% showed a tendency to increase (p=0.064). This trend was reflected by a better objective response in oncological aggressiveness heterogeneous enhancement patterns (Type-3 and Type-4) than a homogeneous enhancement pattern (Type-2) (83% vs. 56% of modified Response Evaluation Criteria in Solid Tumors). This resulted in a similar PFS between the groups (p=0.773), whereas the PPS was significantly worse when the rate of decrease in the attenuation value was ≥40% (p=0.012). A multivariate analysis confirmed that a rate of decease in attenuation value ≥40% was a poor prognostic factor for the PPS (hazard ratio, 2.993; 95% confidence interval, 1.196-7.490; p=0.019). Conclusion A rate of decrease in attenuation ≥40% may reflect a good response of a highly malignant tumor to lenvatinib. Therefore, this value may have utility as a surrogate marker for estimating the oncological aggressiveness of tumors and their associated prognosis.

Abstract
BACKGROUND AND AIM The aim of this study was to identify the utility of 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG-PET/CT) as a predictor of overall prognosis in patients with hepatocellular carcinoma treated with lenvatinib. METHODS Forty-eight consecutive patients who received lenvatinib treatment were reviewed. The oncological aggressiveness of tumors estimated using 18F-FDG-PET/CT was investigated by the analysis of progression-free survival (PFS), post-progression survival (PPS), and overall survival (OS). Multivariate analysis was used to identify potential confounders for OS during lenvatinib therapy. RESULTS Using the Modified Response Evaluation Criteria in Solid Tumors, a tumor-to-normal liver ratio (TLR) ≥2, indicating higher oncological aggressiveness in HCCs, was associated with a better objective response to lenvatinib than a TLR <2 (78 vs. 62%), resulting in a similar PFS (p = 0.751). Because of a significantly worse PPS, OS with a TLR ≥2 was poor compared to a TLR < 2 (p = 0.012). Multivariate analysis confirmed that a TLR ≥ 2 was associated with poor OS (hazard ratio, 2.709; 95% CI, 1.140-6.436; p = 0.024). Analysis of 24 patients who received a repeat 18F-FDG-PET/CT showed that daily changes expressed as ΔTLR × 103/day over the treatment course tended to be different among the types of subsequent treatment. A R0 resection and lenvatinib-TACE sequential therapy provided good disease control (median, -4.593 and -0.024, respectively) compared with other treatments (median, 5.278) (p = 0.075). CONCLUSION Lenvatinib has acceptable disease control regardless of estimated tumor differentiation. A high TLR (≥2) is a poor prognostic factor of OS following lenvatinib treatment, while ΔTLR × 103/day provides useful information of disease control status.

Abstract
Objective A survival benefit was demonstrated for ramucirumab (RAM) in patients with unresectable hepatocellular carcinoma (uHCC) and α-fetoprotein (AFP) concentrations ≥400 ng/mL who had previously received sorafenib (SOR). However, it is unclear whether RAM has a similar efficacy in patients with uHCC that progresses after lenvatinib (LEN) treatment. This study aimed to evaluate the early anti-tumor response to RAM as a second-line treatment for advanced uHCC after LEN treatment. Methods We retrospectively assessed the efficacy and safety of RAM at 6 weeks after initiation. The therapeutic effects were evaluated according to the Response Evaluation Criteria in Solid Tumors version 1.1. Patients We evaluated 7 patients with uHCC who received RAM as a second- or third-line treatment after LEN failure. Results The disease control rate (DCR) was 28.6% (2 of 7 patients). After the initiation of RAM, a rapid disease progression resulted in 1 patient death after 19 days. The median progression-free survival (PFS) was 41 days. There were no grade 3 or 4 treatment-related adverse events. At 6 weeks, there was no deterioration in the modified albumin-bilirubin (mALBI) grade. In patients with an imaging response of stable disease (SD), the rate of AFP production decreased from the baseline. Conclusion RAM may have a therapeutic potential for the suppression of uHCC progression in patients previously treated with LEN, as well as for maintaining the liver function during treatment. Evaluating the AFP trends may therefore be useful for predicting RAM effectiveness.

Abstract
We report a rare case of amebiasis associated with an intraabdominal abscess without colitis, an intestinal perforation, or other extraintestinal amebiasis. A patient was admitted with cirrhosis and a history of spontaneous bacterial peritonitis (SBP) and was found to have a high C-reactive protein (CRP) level. Dynamic CT and ultrasound echo findings showed an intraabdominal abscess. No intestinal lesions or extraintestinal lesions other than the intraabdominal abscess were observed. Blood cultures and puncture fluid cultures were negative for bacteria. However, microscopic examination of the puncture fluid showed a cystic form of amoeba, leading to a diagnosis of an amoeba abscess. The abscess disappeared after 10 days of oral treatment with metronidazole. When an abdominal abscess is seen in an immunocompromised patient such as a cirrhotic patient, amoeba infection should be considered as a possible diagnosis.

Abstract
AIM The number of patients with fatty liver disease (FLD) is increasing globally. Ethanol consumption in FLD is known to be associated with an increased risk of hepatocellular carcinoma (HCC), but the effects of alcohol consumption on the occurrence of multiple HCCs remain unclear. We explored the relationship between the daily ethanol intake and the HCC number. METHODS This single-center retrospective study enrolled 114 patients without viral or immune hepatitis undergoing first-line HCC treatment who had been diagnosed with FLD by abdominal ultrasonography or a liver biopsy at the same time as or before HCC detection. We categorized patients into four groups according to the daily alcohol consumption (<20 g: non-alcoholic fatty liver disease, n = 45; 20-39 g: low-intermediate ethanol intake with FLD, n = 13; 40-69 g: high-intermediate ethanol intake with FLD, n = 31; ≥70 g: alcoholic fatty liver disease, n = 25). The relationship between the daily ethanol consumption and the number of HCCs (single or multiple) was examined. RESULTS The risk of multiple HCCs was significantly higher in the high-intermediate ethanol intake with FLD (HR 2.89, 95% CI 1.04-8.02, P = 0.042) and alcoholic fatty liver disease (HR 3.14, 95% CI 1.07-9.22, P = 0.037) groups than in the others. A multivariate analysis showed that a daily ethanol intake ≥40 g was associated with a significantly increased risk of multiple HCCs (HR 2.82, 95% CI 1.16-6.88, P = 0.023). CONCLUSIONS Our findings suggest that a high daily ethanol intake might lead to multiple hepatocarcinogenesis in patients with FLD.

Abstract
BACKGROUND The aims of this study were to evaluate the efficacy of additional treatment, especially lenvatinib-transarterial chemoembolization (TACE) sequential therapy, for unresectable hepatocellular carcinoma (HCC). METHODS Consecutive 56 patients who underwent lenvatinib treatment were reviewed. Oncological aggressiveness of tumor was estimated using a dynamic CT enhancement pattern classification, and clinical impact of subsequent treatment was investigated through analysis of progression-free survival (PFS), post-progression survival (PPS), and multivariate analysis of potential confounders for survival after progression during lenvatinib therapy. RESULTS Heterogeneous enhancement patterns (Type-3 and -4), which are reportedly associated with higher oncological aggressiveness of HCC, were associated with better objective response to lenvatinib compared to homogeneous enhancement pattern (Type-2) (86 and 85% vs. 53% in modified Response Evaluation Criteria in Solid Tumors), resulting in similar PFS (p = 0.313). Because of significantly worse PPS, overall survival of Type-4 tumor was poor compared to Type-2 or -3 tumors (p = 0.009). However, subgroup of patients who achieved subsequent treatment showed significantly better PPS, regardless of CT enhancement pattern. Multivariate analysis confirmed that use of lenvatinib-TACE sequential treatment after progression during lenvatinib therapy was associated with better PPS (hazard ratio [HR], 0.08; 95% CI, 0.01-0.71; p = 0.023), while Type-4 enhancement pattern was correlated with worse PPS (HR, 2.92; 95% CI, 1.06-8.05; p = 0.039). CONCLUSION Oncological aggressiveness of HCC estimated by CT enhancement pattern was predictive of PPS after progression during lenvatinib. Successful subsequent treatment with lenvatinib-TACE sequential therapy may offer survival benefit regardless of CT enhancement pattern of HCC.

Abstract
BACKGROUND The sensitivity of 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG-PET/CT) in hepatocellular carcinoma (HCC) is low; however, clinical evidence demonstrating its prognostic value in patients with HCC has recently been reported. This study aimed to assess the value of 18F-FDG-PET/CT as a tool for evaluating the response of HCC to lenvatinib treatment. METHODS We evaluated 11 consecutive patients with HCC diagnosed by dynamic CT or magnetic resonance imaging combined with 18F-FDG-PET/CT from April 2018 to December 2019. The tumor-to-normal liver ratio (TLR) of the target tumor was measured before and during the course of lenvatinib treatment with 18F-FDG-PET/CT (pre and post analysis, respectively), with a TLR ≥2 classified as PET-positive HCC. At the time of each evaluation, we also used the Response Evaluation Criteria in Solid Tumors (RECIST) 1.1, the modified RECIST (mRECIST), and the tumor marker alfa-fetoprotein (AFP). RESULTS Of 11 patients, 3 (27%) and 8 (73%) had an objective response to lenvatinib treatment at the time of post-analysis by RECIST 1.1 and mRECIST, respectively. There were 3 (27%) and 7 (64%) patients with PET-positive HCC at the time of pre- and post-analysis, respectively. There was a significant correlation between the rates of change in AFP and TLR during lenvatinib treatment (r = 0.69, p = 0.019). Based on these results, we were able to perform liver resection on 4 patients with PET-positive HCC as conversion therapy. Three samples from these patients showed poorly differentiated tumors. CONCLUSION 18F-FDG-PET/CT has potential as an evaluation tool for describing biological tumor behavior and reflecting disease progression, location, and treatment response. This modality may provide useful information for considering prognosis and subsequent therapy.

Abstract
BACKGROUND The prognostic factors of morbidity and mortality in patients with lean NAFLD (body mass index < 25.0 kg/m2) are unknown. METHODS In this retrospective study, 446 Japanese patients with histopathologically-confirmed NAFLD (lean NAFLD, n = 170) were followed for liver events, cardiovascular events, type 2 diabetes mellitus, and non-liver malignancies. The median observation period was 4.6 years. We also investigated the predictors of severe fibrosis (stage 3-4) and mortality in lean NAFLD patients. RESULTS Glycolipid metabolic markers, liver function tests, NAFLD fibrosis score (NFS), and histological scoring were significantly lower in lean NAFLD patients than in non-lean NAFLD. The incidence of liver cancer was higher while that of T2DM was lower in lean NAFLD. Kaplan-Meier analysis showed no significant difference in overall survival between the lean and non-lean NAFLD. Multivariate analysis of data of lean NAFLD identified NFS ≥ - 1.455 as significant independent predictor of severe fibrosis, while history of liver cancer and NFS ≥ - 1.455 were predictors of overall survival. CONCLUSIONS Although patients with lean NAFLD have better histopathological and biochemical profile compared to patients with non-lean NAFLD, the prognosis is not different between the two groups. Lean NAFLD patients with NFS ≥ - 1.455 or history of liver cancer should be monitored carefully during follow-up.

Abstract
We report a 71-year-old man with non-B non-C chronic liver damage who had been regularly visiting our hospital since he was 38 years of age. He underwent three partial hepatectomies for hepatocellular carcinoma (HCC) diagnosed at 65, 67, and 71 years of age, respectively. A histopathological examination showed moderately-differentiated HCC, and chronic hepatitis with mild fibrosis stage in non-tumor areas. alpha-fetoprotein (AFP) and PIVKAII were not useful for the early prediction of HCC, but TERT promotor mutation (C228T) in serum cell-free DNA was useful. This is the first report on the importance of long-term follow-up in non-B non-C chronic liver damage, regardless of the fibrosis stage.

Abstract
Recent schizophrenia (SCZ) studies have reported an increased burden of de novo copy number variants (CNVs) and identified specific high-risk CNVs, although with variable phenotype expressivity. However, the pathogenesis of SCZ has not been fully elucidated. Using array comparative genomic hybridization, we performed a high-resolution genome-wide CNV analysis on a mainly (92%) Japanese population (1699 SCZ cases and 824 controls) and identified 7066 rare CNVs, 70.0% of which were small (<100 kb). Clinically significant CNVs were significantly more frequent in cases than in controls (odds ratio=3.04, P=9.3 × 10-9, 9.0% of cases). We confirmed a significant association of X-chromosome aneuploidies with SCZ and identified 11 de novo CNVs (e.g., MBD5 deletion) in cases. In patients with clinically significant CNVs, 41.7% had a history of congenital/developmental phenotypes, and the rate of treatment resistance was significantly higher (odds ratio=2.79, P=0.0036). We found more severe clinical manifestations in patients with two clinically significant CNVs. Gene set analysis replicated previous findings (e.g., synapse, calcium signaling) and identified novel biological pathways including oxidative stress response, genomic integrity, kinase and small GTPase signaling. Furthermore, involvement of multiple SCZ candidate genes and biological pathways in the pathogenesis of SCZ was suggested in established SCZ-associated CNV loci. Our study shows the high genetic heterogeneity of SCZ and its clinical features and raises the possibility that genomic instability is involved in its pathogenesis, which may be related to the increased burden of de novo CNVs and variable expressivity of CNVs.

Abstract
AIM Radiofrequency ablation (RFA) is a promising alternative to hepatic resection for the treatment of hepatocellular carcinoma (HCC) located in the caudate lobe. We evaluated the therapeutic efficacy and safety of RFA for HCC located in the caudate lobe compared with HCC located elsewhere in the liver. METHODS Overall, 555 consecutive patients treated by RFA for a single HCC tumor of less than 3 cm diameter, were enrolled in this study, including 20 patients with HCC located in the caudate lobe. Among these 20 patients, HCC was located in the Spiegel lobe in eight patients, in the paracaval portion in another 10 and in the caudate process in two. We evaluated differences in the local recurrence rate and the incidence of complications associated with RFA between the caudate and the non-caudate groups. RESULTS The 4-year cumulative local recurrence rate after RFA in the caudate group and the non-caudate group was 22.3% and 4.5%, respectively (P < 0.001). Multivariate analysis of factors affecting local recurrence demonstrated that tumor size and tumor location (caudate or non-caudate) were independent significant factors. No postoperative complications were observed in the caudate group, whereas 15 patients (2.8%) in the non-caudate group experienced complications related to RFA. CONCLUSION We were able to safely treat HCC located in the caudate lobe by RFA. However, there was a high incidence of local recurrence, presumably because of the heat sink effect of the inferior vena cava and the restricted puncture approach. We should pursue a revised method to reduce local recurrence.

Abstract
This report concerns an autopsy case of late-onset dementia with atypical neuropathological features. The patient was a Japanese man who was 83 years old at the age of death. At 73 years, he developed behavioral disorders, including emotional changes, and dementia. He died at the age of 83. A neuropathological study revealed largely confined involvement of the limbic regions, characterized by degeneration consisting of neuronal loss with a spongy state and gliosis. Massive tau-positive oligodendroglial coiled bodies and argyrophilic threads were also observed mainly in these regions. Although the clinicopathological findings of the present case showed some similarities to those of a unique subtype of frontotemporal dementia, including mesolimbocortical dementia, argyrophilic grain disease, corticobasal degeneration and dementia with tangles, there seems to be no suitable category of neurodegenerative disease into which our case can be classified. Further study is needed to determine whether the present case could be classified as an atypical case of these diseases or represents a new entity.

Abstract
Epidermal growth factor (EGF) comprises a structurally related family of proteins containing heparin-binding EGF-like growth factor (HB-EGF) and transforming growth factor alpha (TGFalpha) that regulates the development of dopaminergic neurons as well as monoamine metabolism. We assessed the contribution of EGF to schizophrenia by measuring EGF family protein levels in postmortem brains and in fresh serum of schizophrenic patients and control subjects. EGF protein levels were decreased in the prefrontal cortex and striatum of schizophrenic patients, whereas the levels of HB-EGF and TGFalpha were not significantly different in any of the regions examined. Conversely, EGF receptor expression was elevated in the prefrontal cortex. Serum EGF levels were markedly reduced in schizophrenic patients, even in young, drug-free patients. Chronic treatment of animals with the antipsychotic drug haloperidol had no influence on EGF levels in the brain or serum. These findings suggest that there is abnormal EGF production in various central and peripheral tissues of patients with both acute and chronic schizophrenia. EGF might thus provide a molecular substrate for the pathologic manifestation of the illness, although additional studies are required to determine a potential link between impaired EGF signaling and the pathology/etiology of schizophrenia.

Abstract
We investigated five Japanese autopsy cases of diffuse neurofibrillary tangles with calcification (DNTC), both clinically and pathologically, and examined the degree and distribution of the basal ganglia lesions, especially in the amygdala, striatum, pallidum, and substantia nigra. The lesions in the amygdala, striatum, and pallidum were classified into three categories (mild, moderate, and severe). The lesions in the substantia nigra were qualitatively judged, compared with normal controls. Severe dementia was observed in four cases neuropathologically showing pronounced neuronal loss in the cerebral cortex, but one case without neuronal loss in the cerebral cortex showed mild memory disturbance. Extrapyramidal signs were evident in three cases. Obvious neuronal loss in the substantia nigra with the presence of Lewy bodies was noticed in four cases. Basal ganglia lesions in all five cases were uniform: the amygdala showed severe to moderate lesions, the caudate nucleus moderate to slight lesions, and the putamen and pallidum slight lesions to normal. Furthermore, the lesions in the amygdala were more prominent in the basolateral group than in the corticomedial group, inconsistent with those in the amygdala of Alzheimer's disease. Moderate lesions were evident in the basolateral group of the amygdala in the case without neuronal loss in the cerebral cortex. In DNTC, the degree and distribution of the basal ganglia lesions, except for nigral lesions, were analogous to those found in Pick's disease with Pick bodies. These clinicopathological findings may contribute to the elucidation of the clinicopathological hallmarks in this disorder.

Abstract
Cognitive decline in elderly schizophrenic patients is an important clinical symptom, but it is often difficult to analyze in detail due to the patient's original residual psychotic symptoms. In this article, the authors provide neuropsychological and neuropathological research information about cognitive decline in elderly schizophrenic patients, especially with reference to Alzheimer's disease (AD). Neuropsychological and neuropathological reports about cognitive impairments are reviewed. The effect of long-term antipsychotic medication upon cognitive function is also discussed. As a result, it is apparent that elderly schizophrenic patients often show cognitive impairments, however, such impairments do not have the characteristics of progressive degenerative illnesses such as AD, and the speed of their progress is very slow. Neuropathological studies have shown that AD brain pathology appears no more frequently among schizophrenic patients than in the normal population. Since making a diagnosis of AD means that the progressive deterioration not only of cognitive function, but also of physical ability, paralleling the degeneration of the central nervous system, can be expected within a few years and appropriate care will be required. One should be very cautious in adding a diagnosis of AD to elderly schizophrenic patients with cognitive impairments.

Abstract
Previous studies have reported that calcium binding proteins, which have important functions in regulating the intracellular ion concentration, may influence the vulnerability of neurons in neurodegenerative disease. It has been observed that the neurons containing calbindin D28K (CB) may in certain circumstances be more resistant to excitotoxic and ischemic injury. In the present study the susceptibility of hippocampal neurons containing CB to develop NFT was studied, and the distribution of CB cells was compared with hippocampal plaque density in the Alzheimer's disease (AD) brain. Interestingly CB-positive hippocampal neurons did not contain tangles and could be seen next to degenerating tau-positive pyramidal cells. Comparison of the hippocampal plaque distribution with that of CB neurons showed that in general CB-positive neurons were found in areas with a low plaque burden. Further comparison of cases with differing degrees of severity indicated that CB-positive neurons were relatively preserved in cases with moderate plaque and tangle content but that in severe cases the CB-positive pyramidal cells were lost. These findings indicate that CB cells may be protected in the earlier stages of the disease but that this resistance ability is lost in the late stages of AD. The observation that CB-positive pyramidal cells do not accumulate NFT suggests that proteolysis of tau differs in CB-negative and CB-positive cells.

Abstract
We report an autopsied case of presenile dementia showing neuropathologically abundant neurofibrillary tangles(NFT) without senile plaques(tangle only dementia). A Japanese woman developed memory disturbance when she was 60 years old. At age of 65, her ability to understand deteriorated and euphoria and wandering manifested but neither psychotic symptoms, including hallucination and delusion nor a change in character were observed. The patient was hospitalized at age 66 and a cranial CT scan revealed bilateral moderate atrophy of the cortex and moderate enlargement of the lateral ventricle, especially in the inferior horn. No lobar atrophy was detected. She exhibited an oral tendency and became appallic at her final stage and died at the age of 75. Autopsy showed that her brain weighed 850 g and neuropathological study showed numerous NFT mainly in the entorhinal (trans-entorhinal) region, subiculum, CA1-CA4, dentate gyrus, amygdara, subthalamic nucleus, basal nucleus of Meynert, substantia nigra and locus coeruleus. Severe neuronal loss with gliosis was noted in the temporal lobes including the hippocampal region. No senile plaque was detected in any of the brain regions. There have been some recent reports of patients with abundant NFT with the predominant involvement of the allocortex but no or very little senile plaque. All the patients in the reported cases were very elderly at onset(over 80 years of age). In our case, the onset was presenile and we could exclude any other diseases, that usually present with NFT, and to our knowledge, this is the first report of a presenile dementia with tangles.

Abstract
The application of DNA array technology to schizophrenic studies enabled us to assess molecular features of this disease. The expression of synapsin II and N-ethylmaleimide-sensitive fusion protein (NSF) mRNAs is reported to decrease in the prefrontal cortex of these patients. We attempted to reproduce this result with two distinct approaches. With high quality samples, mRNA and protein levels for synapsin II and NSF were measured by real-time polymerase chain reaction and by immunoblotting. Both experiments led to the same conclusion: The expression of these presynaptic markers is not altered significantly in the prefrontal cortex of our schizophrenic samples, compared to that in control subjects. These observations suggest that the neurochemical impairments of synapses reported in schizophrenia are not evident for all presynaptic markers and needs to be re-evaluated at molecular levels.

Abstract
The neurodevelopmental hypothesis is now being recognized as one of the most useful hypothesis for schizophrenia, and by using it, abnormalities in protein associated with neuron growth or neuronal migration have been reported. From neuron-glia interrelations in the neural development, it is important to study the function of astroglia in the schizophrenic brain. In this study, we examined the neuropathological reaction of astroglia using lobotomized brains, and a significant decrease of astroglia after artificial histological damage was observed in schizophrenic brains. We speculated that this may be due to the latent vulnerability of the dynamic function of astroglia in schizophrenia. Astroglia plays a guidance role on migration and if astroglia has latent vulnerability, we speculate that younger neurons may not sufficiently migrate during development. In further investigation of the neurodevelopmental hypothesis of schizophrenia, it will be necessary to examine the function of astroglia.

Abstract
The biological actions of extracellular nucleotides are mediated by two distinct classes of P2 receptor, P2X and P2Y. The G protein-coupled P2Y receptors comprise five mammalian subtypes, P2Y(1-11). The P2Y1 subtype is expressed abundantly throughout the human brain and is specifically localized to neuronal structures. In the present study, the distribution of the P2Y1 receptor was investigated in Alzheimer's disease (AD) brains. In contrast to control human brain, the P2Y1 receptor was localized to a number of characteristic AD structures such as neurofibrillary tangles, neuritic plaques and neuropil threads. Immunoblot analysis showed that this specific immunostaining observed over tangles was not a result of cross-reactivity between the anti-P2Y1 antiserum and abnormal tau protein, the major constituent of tangles. The significance of this altered P2Y1 cellular distribution in AD brains is at present unclear.

Abstract
Recent studies have demonstrated the involvements of gamma-aminobutyric acid (GABA) neurotransmitter systems in the schizophrenic brain. In order to further elucidate the alterations of this system in schizophrenia, we employed immunohistochemical techniques and examined the expression and anatomical distribution of the GABA(B) receptor in the hippocampus of five subjects with schizophrenia and three age-matched controls. In the control hippocampus, the most intense immunoreactivity was observed in the soma and processes of multipolar interneurons throughout the hippocampus. Pyramidal cells too were intensely labeled in their soma and proximal portion of dendrites, although the labeling intensity was varied in each subregion. For example, in the CA1 subfield, the labeling intensity of pyramidal cells was much less intense than that in the CA3 and CA2 subfields. In the subjects with schizophrenia, GABA(B) immunoreactivity was markedly reduced in granule cells as well as in pyramidal cells throughout the CA fields. In interneurons, GABA(B) labeling was relatively preserved compared to that in pyramidal cells. Our findings suggest that in the hippocampus of schizophrenic patients the expression of the GABA(B) receptor is reduced, and raise the possibility that this reduction contributes to the pathophysiological process in the schizophrenic brain.

Abstract
1. The authors observed NPY-positive fibers in the CA4 area of the hippocampus from schizophrenics and normal controls using immunohistochemical techniques. 2. Positive fibers followed a straight course and were oriented to exit the CA4 region of hippocampus in normal controls. 3. Many NPY-positive fibers in the CA4 area appeared coiled or helix-like or appeared wasted and thread-like in schizophrenic brains, compared to those of normal controls. 4. These findings may indicate a dysfunction of the interneuron in the schizophrenic brain and support the hypothesis of developmental impairments of the CNS in schizophrenia, and these morphological changes in fibers may relate to schizophrenic symptoms such as memory or/and learning deterioration.

Abstract
The distribution of neuropeptide Y (NPY) and Brain-Derived Neurotrophic Factor (BDNF) in the hippocampal formation of monkey and rat brains was studied immunohistochemically. The NPY-neuronal system is more highly developed in the monkey compared to that in the rat. The distribution of NPY-positive products was coincident with that of abundant BDNF-positive deposits. These observations suggest that the role of BDNF and the interaction of BDNF-NPY may differ between species.

Abstract
This report concerns an autopsy case of amyotrophic lateral sclerosis (ALS) with unusual clinical and neuropathological findings. The patient was a Japanese man without hereditary burden who was 49 years old at the time of death. His clinical manifestation included dysarthria at age 48, followed by dysphagia, atrophy and fasciculation of the tongue, muscle weakness in the four extremities, tremor, rigidity, increased deep tendon reflexes in the upper and lower extremities, and incoordination of the four extremities. He died of respiratory failure 12 months after the disease onset. No respirator administration was performed throughout the clinical course. The neuropathological examination revealed not only degeneration of upper and lower motor neuron systems, including the presence of Bunina bodies and ubiquitin-immunoreactive neuronal inclusions in the lower motor neurons, but also prominent degeneration of the substantia nigra and dentate nucleus with slight neuronal loss in the locus ceruleus and pontine nucleus. To our knowledge, this is the first reported case of sporadic ALS without dementia and respirator support, showing degeneration of the substantia nigra and dentate nucleus. This report may contribute to the resolution of the question concerning the neuropathological heterogeneity of sporadic ALS with respiratory support.

Abstract
1. The authors studied the morphology of CalbindinD28K (CaBp) immunoreactive cells and processes in the hippocampal formation and the prefrontal cortex of schizophrenics using the immunohistochemical technique of avidin-biotin-complex method (ABC method), and the results were compared with those from normal human brains. 2. In the hippocampal formation area CA2 of schizophrenics, many CaBp-immunopositive cell bodies and fibers were disordered in their arrangement compared to normal control brains. 3. In the prefrontal cortex (Brodmann area 9) of schizophrenics, many immunopositive cell bodies were exhibited irregular axis arrangement and fiber disarray. 4. The altered distribution pattern of CaBp-immunopositive structures in the hippocampal formation and the prefrontal cortex might indicate the existence of GABA(gamma-aminobutyric acid)ergic dysfunction in the brain of schizophrenic patients.

Abstract
Argyrophilic glial inclusions occur in the midbrain of patients with Parkinson's disease (PD) and diffuse Lewy body disease (DLBD). These inclusions are immunohistochemically positive for NACP/alpha-synuclein but negative for tau protein. The results of the present study suggest that a primary degenerative process involves NACP/alpha-synuclein in PD and DLBD and that the process takes place not only in neurons but also in glial cells. Argyrophilic cytoplasmic inclusions, both glial and neuronal, in a variety of degenerative diseases may be grouped into two major categories; one related to aggregates of abnormally phosphorylated tau protein and the other to unusual accumulations of NACP/alpha-synuclein.

Abstract
We examined the apolipoprotein E (ApoE) genotypes of 19 middle-aged non-demented subjects with cerebral amyloid beta protein (Abeta) deposits, and compared the results with those of 16 patients with sporadic Alzheimer's disease (AD) and those of 34 age-matched controls. The frequency of the ApoE epsilon4 allele was higher (P = 0.0256) in these 19 subjects (0.211) than in controls (0.059), and was close to that in AD patients (0.281). This result suggests that middle-aged non-demented subjects with cerebral Abeta deposits are at high risk of developing AD, and that the diffuse Abeta deposits in these cases represent an early stage of AD pathology. We speculate that in the majority of late-onset sporadic AD patients, cerebral Abeta deposition commences when these patients are in their forties or fifties, and that the pathological process progresses gradually, taking 20 to 30 years for clinical manifestation of dementia.

Abstract
The Gallyas-Braak silver impregnation method revealed neurons containing well-defined intraneuronal granules in both Alzheimer's disease and normal control brains. The granules were immunostained prominently with the Alz-50 antibody and, to a lesser degree, with the tau-2 antibody, but not with other anti-tau antibodies examined. The areas of distribution of granule-containing neurons detected by the Gallyas-Braak method appeared to overlap with the reported main sites of subcortical distribution of neurofibrillary tangles. They, however, were not observed in the cerebral cortex, including the hippocampal region. The Alz-50 immunoreactive granules showed ultrastructural features similar to those of lysosomes or lipofuscin. These findings suggest that denatured tau might be degraded in lysosomes.

Abstract
To investigate the psychophysiological features of methamphetamine (MAP) dependence, we recorded auditory event-related potentials (ERPs) in 15 patients with MAP dependence and in 15 age-matched normal controls. ERPs were recorded during a standard oddball task and a read task similar to those employed by Squires et al. (Squires NK, Squires KC, Hillyard SA [1975] Two varieties of long-latency positive waves evoked by unpredictable auditory stimuli in man. Electroenceph Clin Neurophysiol 38:387-401). The patients with MAP dependence showed reduced P3a amplitude and area in the read task and delayed P3b latency with normal P3b amplitude and area in the oddball task. These results suggest that central noradrenergic dysregulation may persist after the remission of acute psychotic symptoms in MAP psychosis and that chronic MAP dependence would produce impairment of the frontal cortex.

Abstract
The brains of 125 schizophrenic patients (DSM-IV criteria) without other major diseases likely to affect brain morphology were examined at autopsy in our hospital for an evaluation of the number of neurofibrillary tangles (NFT) and senile plaques (SP) as indicators of the incidence of Alzheimer's disease (AD) brain pathology. The clinical degree of dementia and the presence or absence of delirium and Parkinsonism were determined in a review of the patients' charts. No significant difference in the degree of AD brain pathology between the 12 schizophrenics more than 75 years old and 12 age-matched normal controls was present. We conclude that AD pathology seems to be no more frequent among schizophrenic patients than in the normal population, and that the severe cognitive impairment observed in schizophrenics is based on neither neuronal degeneration nor neuronal loss like that occurring in AD. We believe that future morphological studies of cognitive impairments in schizophrenics will require a more detailed investigation at the receptor level.

Abstract
We report an elderly patient with progressive supranuclear palsy (PSP) who showed no neurological signs clinically. A 70-year-old man presented with irritation and poor hygiene, thereafter he showed excitement and violence. A cranial CT scan revealed bilateral moderate atrophy of the temporal lobes and slight enlargement of the lateral ventricle. The brain stem was slightly atrophic. Although he died at the age of 80 years, he had no neurological signs throughout the clinical course. Neuropathological study showed typical findings of PSP, neuronal loss with gliosis and neurofibrillary tangles in the basal ganglia, amygdala, midbrain, pons, dentate nucleus and inferior olivary nucleus. Staining by Gallyas-Braak methods revealed argyrophilic and tau-positive glial fibrillary tangles in the cerebral cortex. Neurofibrillary tangles showed greater frequency than usual for the physiological level in that age group in the hippocampus regions as well as in the amygdala. The possibility that the psychotic symptoms, mainly personality change, are connected with the degeneration of limbic system is indicated. Since there have not been any previous reports of PSP without neurological signs, this case represents an important in terms of clinico-pathological variation of PSP. We suggest that there is discrepancy between symptomatic and neuropathological aspects in elderly patients with PSP.

Abstract
To investigate whether there is an epidemiological correlation between Borna disease virus (BDV) infection and human neuropsychiatric diseases, we established a reverse-type sandwich enzyme-linked immunosorbent assay (RS-ELISA) for detecting specific antibodies to BDV. In this assay, microplate wells were coated dispersely with BDV p40 antigen, followed by the addition of test samples at a low dilution and then the biotinylated p40. A preformed complex of streptavidin and horseradish peroxidase-conjugated biotin and an enzyme substrate were used to measure the captured biotinylated p40. Theoretically, RS-ELISA should specifically detect anti-BDV antibodies without nonspecific signals; such signals possibly occur in conventional serological assays. Additionally, the RS-ELISA could be applied under the same protocols to test samples from a variety of animals. By using anti-BDV rat and rabbit sera, the assay was standardized so that it had high specificity and sensitivity. When we used the RS-ELISA to determine the presence of anti-BDV antibodies in plasma from 70 patients with chronic schizophrenia as well as 40 healthy individuals in the Tokyo area of Japan, no plasma sample was found to possess specific antibodies to BDV p40, indicating no association between BDV infection and the disease in our testing population. A negative reaction was also shown for the sera that had previously been judged to be seropositive for BDV by an immunofluorescence or immunoblot test. These findings suggested that false-positive cases of infection due to nonspecific reactions may be included in previous seroepidemiological information with regard to BDV.

Abstract
We developed a simple and sensitive microplate hybridization procedure with which to identify Borna disease virus cDNA in amplified products from human peripheral blood mononuclear cells. The mean values for the positive PCR products were significant compared with those for any of the negative products, indicating that this method can be applied to rapidly diagnose a large number of clinical specimens.

Abstract
A 57-year-old woman showed progressive sensory aphasia as an initial symptom, and then developed total aphasia within 6 years and, finally, severe dementia. Neuropathologically, the cerebral cortex was most severely affected in the superior and transverse temporal gyri, and subsequently in the inferior frontal gyrus, especially in the pars opercularis. The degeneration in the subcortical grey matter was most severe in the substantia nigra, and it was moderate to mild in the ventral part of thalamus, globus pallidus and striatum. Cytopathologically, in addition to achromatic ballooned neurons, massive taupositive types of cytosekeletal abnormalities were observed both in neurons and glia, mainly in the degenerating region. This cytoskeletal pathology coincided with that reported in corticobasal degeneration (CBD). On Bodian staining, only a few neurofibrillary tangles were found in the entorhinal pre-alpha layer and substantia nigra. Pick's bodies and senile plaques could not be found. This case is thought to represent a type of CBD, but with its cortical lesion focus located in the speech area instead of the frontoparietal region. A survey of 28 pathologically evaluated cases of CBD revealed two similar cases, both of which began with progressive aphasia and presented cortical degeneration in the superior temporal gyrus. An overview of CBD cases clarified the features in another group of cases, in which the cerebral accentuated focus was shifted forward from the central region, clinically resembling Pick's disease. The clinical manifestations in CBD seem to be the expression of these diverse cortical lesions. Primary progressive aphasia may include cases of CBD with involvement of the language center.

Abstract
"Diffuse neurofibrillary tangles with calcification (DNTC)" is a slowly progressive form of presenile dementia characterized by localized temporal atrophy, pronounced calcareous deposits and numerous neurofibrillary tangles (NFTs) without senile plaques. We report a 70-year-old woman with DNTC, multiple infarctions and hyaline arteriosclerosis. This case was clinically characterized by persistent delusional ideas and personality changes. Intellectual deterioration was mild, and no focal manifestations were noted. Neuropathologically, numerous NFTs were seen distributed primarily in the hippocampal region, and massive calcareous deposits were observed in the cerebrum, basal ganglia and cerebellum. There were no senile plaques. Although the findings in this case were compatible with a diagnosis of DNTC, certain additional findings were also noted. The first was the presence of multiple infarctions in the basal ganglia and hyaline arteriosclerosis. Although these lesions may have been induced by hypertension, our review of previous reports of DNTC revealed a high incidence of arteriosclerosis. The second was the absence of lobar atrophy, which may have been due to the cerebral edema caused by the subdural hemorrhage or related to the relatively short duration of the illness. The dilatation of the temporal horn of the lateral ventricle and prominent NFTs in the hippocampal region indicate the initial occurrence of the disease in this region.

Abstract
Ultrastructural examination of ghost tangles in an autopsy case of long-term Alzheimer's disease revealed, in addition to degenerate neurites containing paired helical filaments (PHF), astrocytic processes which included PHF. This finding suggests either that astrocytes in ghost tangles possess the capacity to produce PHF or that PHF are incorporated into astrocytes by endocytosis.

Abstract
Some ghost tangles in the brains of Alzheimer patients were accompanied by many small argyrophilic structures which were electron microscopically confirmed to be degenerate neurites. In these ghost tangles, roughly dispersed 15 nm straight and occasional twisted tubules were penetrated by proliferated astrocytic processes. Immunohistochemically, these ghost tangles lost immunoreactivities to anti-NFT, -tau and -ubiquitin antibodies, but were thioflavine-S fluorescent, though antigenicity to beta-protein was not proved. This similarity in composition of degenerate neurite-bearing ghost tangles to senile plaques might be induced by the amyloid nature of tubules, which probably provokes the reaction of neuropils.

Abstract
The distribution of somatostatin-immunoreactive cell bodies and processes was studied in the cerebral cortex of the macaque monkey (Macaca fuscata), by applying an immunohistochemical technique with a monoclonal antibody raised against somatostatin tetradecapeptide. Many somatostatin-immunoreactive cell bodies and processes were observed in all regions of the cerebral cortex, i.e., frontal, parietal, temporal, insular, occipital, and cingulate cortices, and also in the underlying white matter. Three types of somatostatin-containing cell bodies were distinguished in the cerebral cortex. These cell bodies were distributed in layers II to VI of the cortex, and also in the underlying white matter. There were dense deposits of somatostatin-containing granular structure in layers I and II, and many somatostatin-containing processes in layers IV and V. The present observations demonstrate that in the primate neocortex somatostatin 14-containing neuronal systems are as highly developed as other prosomatostatin-derived peptides but differ from the latter systems in terms of cell morphology and fiber distribution.

Abstract
The distribution of substance P-containing fibers in the cerebral cortex and the hippocampal formation of the Japanese monkey (Macaca fuscata fuscata) was studied by immunohistochemistry using a monoclonal antibody raised against substance P. The results were compared with the distribution in homologous regions of the rat brain. Substance P-containing fibers and cell bodies were observed in all regions of the cerebral cortex. In deep layers of the neocortex (IV-VI), substance P-immunoreactive fibers formed arrays that ran perpendicular to the surface. These immunoreactive fibers tended to branch as they approached the cortical surface in layers II and III, at which point they were oriented in many directions. The molecular layer (I) of the monkey neocortex contained many granular, substance P-immunoreactive structures, resembling terminal boutons. In contrast to the monkey, rat cortical areas contained substantially fewer substance P-containing fibers. The immunoreactive profiles, mostly fine dot-like structures, were seen uniformly in layers II and IV of the rat neocortex, although in the medial prefrontal cortex many thick, varicose fibers were also observed. Substance P-containing fibers were seen throughout the hippocampal formation of the monkey, including the subiculum and the parahippocampal regions. The regional distribution of immunoreactive fibers was most dense in the molecular layers of dentate gyrus, in the stratum moleculare of the CA1 region, and in the stratum pyramidalis of the CA2 region. In the rat, the hippocampus and dentate gyrus contained fewer immunoreactive fibers. Moderate densities were observed in the rat subiculum and entorhinal cortex.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Two hundred and forty-four patients with various subtypes of DSM-III anxiety disorder were found among 3,059 outpatients who visited our clinic consecutively for evaluation for five years. They included 53 patients with panic disorder comprising an outstanding number of patients, about a quarter of patients with anxiety disorder and 1.7% of the whole outpatient population, and 78 with generalized anxiety disorder. Differentiation between these two groups was difficult to make besides their specific clinical features whether the patient had panic attacks or chronic generalized anxiety. The patients with anxiety disorder were divided into two major groups--panic-generalized anxiety-simple phobia and social phobia-obsessive compulsive-agoraphobia--in respect to their age of onset of the illness, the duration of episode, separation from their parents, psychosocial stressors and response to pharmacotherapy. Social phobia and obsessive compulsive disorder comprised those patients with similar qualities to each other in terms of their demographic data and their social backgrounds, forming a distinct group apparently different from the panic-generalized anxiety group. They consisted predominantly of young male patients with an earlier onset of the illness, less separation experienced and a longer duration of the episode, while without meaningful psychosocial stressors preceding the present episode. These findings indicate that the prevalence of panic disorder in the Japanese population is as high as previously reported, although its discriminant factors from generalized anxiety disorder are ambiguous except for panic attacks.

Abstract
Bacillus subtilis and Bacillus brevis 47-5, carrying the Bacillus stearothermophilus alpha-amylase gene on pUB110 (pBAM101), synthesized the same alpha-amylase as the donor strain as determined by the enzyme's thermal stability and NH2-terminal amino acid sequence. Regardless of the host, the 34-amino acid signal peptide of the enzyme was processed at exactly the same site between two alanine residues. B. brevis 47-5(pBAM101) secreted the enzyme most efficiently of the hosts examined, 100, 15, and 5 times more than B. stearothermophilus, Escherichia coli HB101(pH1301), and B. subtilis 1A289(pBAM101), respectively. The efficient secretion of the enzyme in B. brevis 47-5(pBAM101) was suggested to be due to the unique properties of the cell wall of this organism.
