Abstract
OBJECTIVES To investigate the clinical significance of serum cytokine profiles for differentiating between Kawasaki disease (KD) and its mimickers. METHODS Patients with KD, including complete KD, KD shock syndrome (KDSS), and KD with macrophage activation syndrome (KD-MAS), and its mimickers, including multisystem inflammatory syndrome in children, toxic shock syndrome, and Yersinia pseudotuberculosis infection, were enrolled. Serum levels of interleukin (IL)-6, soluble tumor necrosis factor receptor type II (sTNF-RII), IL-10, IL-18, and chemokine (C-X-C motif) ligand 9 (CXCL9) were measured using enzyme-linked immunosorbent assay and compared them with clinical manifestations. RESULTS Serum IL-6, sTNF-RII, and IL-10 levels were significantly elevated in patients with KDSS. Serum IL-18 levels were substantially elevated in patients with KD-MAS. Patients with KD-MAS and KD mimickers had significantly elevated serum CXCL9 levels compared with those with complete KD. Area under the receiver operating characteristic curve analysis showed that serum IL-6 was the most useful for differentiating KDSS from the others, IL-18 and CXCL9 for KD-MAS from complete KD, and CXCL9 for KD mimickers from complete KD and KD-MAS. CONCLUSION Serum cytokine profiles may be useful for differentiating between KD and its mimickers.

Abstract
AIM To determine whether the pathological response to preoperative chemotherapy for pancreatic ductal adenocarcinoma (PDAC) can be predicted using 2-[18F]-fluoro-2-deoxy-d-glucose positron-emission tomography (F-18 FDG-PET). MATERIALS AND METHODS Twenty-eight patients with PDAC who underwent only neoadjuvant chemotherapy (NAC) before surgery were enrolled in the study. All patients had F-18 FDG-PET examinations before NAC. The resected specimen was pathologically evaluated according to the Classification of Pancreatic Carcinoma (7th edn). Patients were categorised into a non-response group and a response group based on the pathological findings. The non-response group (Grades 1a and 1b) showed ≤50% necrosis in the specimen, while the specimens of the response group (Grades 2-3) showed >50% necrosis. The maximum standardised uptake values (SUVmax) of the tumours on F-18 FDG-PET were measured. The mean values of SUVmax were compared between the two groups. The diagnostic performance of SUVmax in distinguishing the two groups was also evaluated using receiver operating characteristic analysis. RESULTS The mean SUVmax of the response group was higher than that of the non-response group (9.00 ± 1.78 versus 4.26 ± 2.35; p<0.001). The optimal cut-off value of SUVmax was 9.28 for distinguishing the two groups. The sensitivity, specificity, and accuracy for the prediction in the response group were 80%, 95.7%, and 92.9%, respectively. CONCLUSIONS SUVmax on F-18 FDG-PET may be useful as a biomarker to predict the pathological response to NAC in patients with PDAC.

Abstract
Abstract
Purpose/objective(s)
To report results from our phase II study of stereotactic body radiotherapy (SBRT) delivering 36 Gy in 4 fractions for patients with localized prostate cancer.
Materials/methods
We enrolled 55 patients treated with SBRT delivering 36 Gy in 4 fractions between 2015 to 2018. All patients were categorized as low-risk (n = 4), intermediate-risk (n = 31) or high-risk (n = 20) according to National Comprehensive Cancer Network criteria. Median age was 73 years (range 54–86 years). Two-thirds of patients (n = 37) had received androgen-deprivation therapy for 3–46 months (median, 31 months). Median duration of follow-up was 36 months (range 1–54 months). We used Radiation Therapy Oncology Group and National Cancer Institute—Common Toxicity Criteria version 4 for toxicity assessments. Quality of life (QOL) outcomes were also evaluated using the Expanded Prostate Cancer Index Composite (EPIC).
Results
Protocol treatments were completed for all patients. Six patients experienced biochemical failures. Among these six patients, three patients experienced clinical failure. One patient showed bone metastasis before biochemical failure. One patient died of gastric cancer. The 3-year biochemical control rate was 89.8%. Acute grade 2 genitourinary (GU) and gastrointestinal (GI) toxicities were observed in 5 patients (9%) and 6 patients (11%), respectively. No grade 3 or higher acute toxicities were observed. Late grade 2 GU and GI toxicities were observed in 7 patients (13%) and 4 patients (7%), respectively. Late grade 3 GU and GI toxicities were observed in 1 patient (1.8%) each. EPIC scores decreased slightly during the acute phase and recovered within 3 months after treatment.
Conclusion
Our phase II study showed that SBRT delivering 36 Gy in 4 fractions was safe and effective with favorable QOL outcomes, although this regimen showed slightly more severe toxicities compared to current standards.

Abstract
A 12-year-old boy visited our hospital with complaints of chronic cough and dyspnea. Chest X-ray and CT revealed diffuse granular shadow in the bilateral lung fields and "Tree-in-bud appearance" in the peripheral airways, respectively. Sinusitis was present, and restrictive disorder was predominantly found in pulmonary function. The patient was diagnosed with DPB, and long-term therapy was started with low-dose clarithromycin (CAM), The patient showed a dramatic response to CAM, with improvements of both the clinical symptoms and pulmonary function within 1-2 months. According to the relevant literature, in adult patients with this disease, pulmonary dysfunction starts from an obstructive pattern; however, this is not the case in pediatric patients. It was therefore suggested that the mechanisms underlying the development of pulmonary dysfunction in cases of childhood onset differs from those with an adult onset.

Abstract
We have been developing a position measurement system for navigation of automated guided vehicles (AGVs) called SPARS. In this system, the AGV’s ultrasonic position measurement module communicates via ultrasonic waves with ultrasonic transponders that serve as land markers on a path to measure its relative position during travel. In previous studies, we conducted experiments and introduced improvements using the relative position between the AGV and land marker estimated from position information from a single land marker. It was found, however, that the ultrasonic communication S/N ratio decreases, lowering position accuracy, when the land marker distance and its direction angle are great. To solve this problem and improve accuracy, we examine position measurement based on distance information from two land markers.

Abstract
OBJECTIVE To reveal the specific ultrasonic imaging findings of non-visible necrotic tissue in pressure ulcers (PUs) with undermining and describe the images objectively. The predictive validity of the specific images of the undermined necrotic tissue was also determined. METHOD Using digital ultrasonography (12 MHz linear transducer, MyLab25; Hitachi Medical Corporation), we imaged PUs with undermining every 2 weeks. PUs were also monitored by DESIGN-R, a PU assessment tool, at the same time. RESULTS Ten patients had 11 PUs with undermining and all ulcers were located in the sacral region. The necrotic tissue showed high echogenicity with no layers, unclear borders and an uneven gray level (cloud-like image). Granulation tissue appeared as a low echoic image which had no layers, was of coarse resolution and an even gray level. There were significant differences between the pixel uniformity of the necrotic tissue (84.0) and granulation tissue (53.9) compared with uninjured tissue (65.5; p=0.000 and 0.005, respectively). The sensitivity, specificity, and positive and negative predictive values of cloud-like image were 87.5%, 91.7%, 77.8% and 95.6%, respectively. CONCLUSION The results suggest that cloud-like image is the most useful diagnostic indicator for non-visible necrotic tissue in PUs with undermining and is the best prognostic indicator for PU healing.

Abstract
OBJECTIVE The availability of nutritional screening tools for older adults is limited, depending on their physical characteristics or the setting. We investigated the relationships between various nutritional indicators and skin conditions as possible screening indicators. DESIGN Cross-sectional study. SETTING A long-term care hospital in Japan. PARTICIPANTS 90 elderly residents who were aged ≥65 years old. MEASUREMENTS The nutritional status of the residents was assessed by body mass index (BMI), involuntary weight loss, arm muscle area, and serum albumin and prealbumin levels. Leg skin condition was evaluated by: 1) functional factors including pH, hydration and transepidermal water loss; 2) skin color including L*, a*, b* and individual typology angle (ITA°) using a tristimulus colorimetric instrument; and 3) skin morphology. Repeated measures analysis of variance was employed, adjusted for demographic characteristics and room temperature, with measurement site as the repeated variable. RESULTS Among the skin indicators, b* was significantly correlated with BMI (p=0.018), and weight loss over the previous month (p=0.042) and 6 months (p=0.002). Additionally, ITA° was associated with weight loss over 1 month (p=0.013). Both b* and ITA° showed the area under the receiver operating characteristic curve of 0.64 to 0.80 for weight loss >2% over 1 month. CONCLUSIONS Residents with poorer nutritional status had yellower and darker skin color.

Abstract
We evaluated the potential use of intraoperative gelatin matrix hemostatic sealant (GMHS; FloSeal; Baxter Healthcare) embedded with macrophages (Mphi) transduced with murine interleukin (IL)-12 recombinant adenoviral vector (G/Mphi/AdmIL-12) for prevention of recurrence of prostate cancer following radical prostatectomy. Application of G/Mphi/AdmIL-12 resulted in significant suppression of tumor growth and spontaneous lung metastases, a statistically significant survival advantage of the G/Mphi/AdmIL-12-treated animals, more efficient trafficking of Mphi to lymph nodes draining from the prostate and generation of systemic natural killer cell activity and tumor-specific cytolytic T lymphocyte responses compared to the controls in a preclinical mouse model of residual prostate cancer. Our data recommend this treatment as a novel adjuvant for prevention of local recurrence of prostate cancer following radical prostatectomy.

Abstract
We investigated the potential benefits of combining adenoviral vector mediated in situ interleukin-12 (AdmIL-12) gene therapy with radiation therapy (XRT) to enhance therapeutic efficacy. In a metastatic mouse prostate cancer cell line, 178-2 BMA, AdmIL-12+XRT demonstrated enhanced therapeutic activities in vitro as determined by clonogenic survival, apoptosis, and mIL-12 levels. At the molecular level, increased expression of tumor necrosis factor-alpha mRNA was specific for the combined therapy. In a subcutaneous 178-2 BMA in vivo model, the combination of AdmIL-12+XRT produced statistically significant tumor growth suppression compared to control vector Adbetagal, Adbetagal XRT, or AdmIL-12 as monotherapy. In addition, significant prolongation of survival was demonstrated for the combination of AdmIL-12+XRT. The combination of AdmIL-12+XRT significantly suppressed both spontaneous and pre-established lung metastases, and led to a prolonged elevation of serum IL-12 and significantly increased natural killer (NK) activities. Importantly, in vivo depletion of NK cells resulted in significant attenuation of the antimetastatic activities of AdmIL-12 alone or AdmIL-12+XRT. These combined effects suggest that AdIL-12 gene therapy together with radiotherapy may achieve maximal tumor control (both local and systemic) in selected prostate cancer patients via radio-gene therapy induced local cytotoxicity and local and systemic antitumor immunity.

Abstract
We previously identified a novel p53 target gene, RTVP-1, that possesses unique cytotoxic and immunostimulatory activities which make it potentially useful for cancer gene therapy. To test the therapeutic potential of RTVP-1 in a gene-modified tumor cell-based vaccine model, we used an adenoviral vector capable of efficient transduction and expression of RTVP-1 (AdRTVP-1), together with a highly metastatic mouse prostate cancer cell line (178-2 BMA). A vaccine was prepared with 178-2 BMA cells transduced with AdRTVP-1 or a control adenoviral vector expressing beta-galactosidase (Adbetagal). After irradiation of the cells, syngeneic 129/Sv mice were vaccinated three times at weekly intervals. After 3 weeks, they were challenged with orthotopic 178-2 BMA cells. After 21 days, fewer than 60% of the RTVP-1-cell-vaccinated mice developed tumors compared to 100% of the control mice. The RTVP-1-cell vaccine significantly reduced primary tumor wet weight compared with control Adbetagal-cell vaccine (P<0.0001 at 7 and 14 days). Experimental metastasis to lung was also significantly reduced (P=0.0377), and survival significantly increased (P=0.0002). In addition, significantly increased NK and CTL activities were demonstrated in the AdRTVP-1-cell-vaccinated mice. These findings indicate that RTVP-1 gene-modified cell-based vaccines may be useful in the prevention of recurrent prostate cancer.

Abstract
A packed bed bioreactor using charcoal pellets produced from waste mushroom medium by thermal carbonization was developed and applied to continuous acetic acid production. The pellets were characterized by their high specific surface area (200 m2/g) with numerous micropores (2-10 microm). The continuous acetic acid fermentation started up smoothly after seeding and was successfully operated for about 180 d under various retention times. The maximum acetic acid productivity was about 3.9 g/l/h using normal aeration and 6.5 g/l/h using air enriched with 40% O2. The pellets are expected to prove useful as a new packing material for bioreactor in terms of their bacterial affinity, high specific surface area with appropriate pore sizes for bacteria, as well as the operational stability of the system and the low production cost.

Abstract
Photolysis of 1,3,5-trichlorobenzene (TCB) in moderate concentration (0.5 mM) in the presence of several additives was examined in 10 mM of cationic and nonionic surfactant solutions. Additions of small amounts of hydrophobic additives, n-dodecanethiol (1 mM), n-dodecyldimethylamine (<2.5 mM), and N-(n-dodecyl)-N-methylaniline (C12An: <0.5 mM), were effective for photodechlorination of TCB, while the formation of by-products could not be inhibited perfectly. In contrast, exclusive and efficient dechlorination of TCB in cetyltrimethylammonium chloride solution was achieved in the presence of sodium borohydride (<5 mM), which was due to the enhanced local concentration of borohydride anions in cationic micelle surfaces.

Abstract
Poly(aspartic acid) (PAA) hydrolase was purified from Sphingomonas sp. KT-1 (JCM10459). The purified hydrolase degraded thermally synthesized PAA to oligomers. The molecular mass of PAA hydrolase was 30 kDa and the isoelectric point was 8.9. The optimum values of pH and temperature for PAA degradation were 10.0 and 40 degrees C, respectively. The investigation of the effect of inhibitors for the PAA-degrading activities has revealed that the PAA hydrolase is a serine-type hydrolase. The structural analysis of PAA-degraded products using (1)H and (13)C nuclear magnetic resonances has indicated that the purified enzyme hydrolyzes selectively the beta-amide linkage connecting with beta-aspartic acid units in PAA.

Abstract
BACKGROUND Porokeratosis is a dyskeratotic disorder of the skin characterized by cornoid lamella with parakeratosis, hyperkeratosis and loss of granular layers. The pathogenesis of porokeratosis and the mechanism(s) of its abnormal keratinization are still unknown. OBJECTIVE To elucidate the mechanism(s) of abnormal keratinization that leads to the formation of cornoid lamellae in porokeratosis. METHODS Apoptosis of keratinocytes was assessed in the skin of seven patients by an in situ apoptosis assay based on the terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick-end labelling (TUNEL) reaction. Patterns of loricrin and involucrin expression were examined by immunohistochemistry. RESULTS TUNEL-positive keratinocytes were observed in the epidermis underlying the cornoid lamella in all cases examined. Furthermore, loricrin expression was interrupted there, in contrast to involucrin, which was expressed diffusely in the lesional epidermis. CONCLUSIONS These results suggest that an abnormal early keratinocyte apoptosis accompanied by dysregulation of terminal differentiation of those cells may be involved in the pathogenesis of porokeratosis.

Abstract
Microbial degradation of thermally synthesized poly(aspartic acid) (PAA) was investigated. A PAA-P1 sample (Mn, 7500; Mw, 20,000; number of branched units/100 monomer units, 3.1) was completely degraded in natural river water within 15 days at 25 degrees C. A new PAA-degrading bacterium (strain KP-2: JCM10638) was isolated together with Sphingomonas sp. KT-1 (JCM10459) from river water, and identified as a member of Pedobacter. A Pedobacter isolate was capable of degrading high-molecular-weight PAA polymers of 5000 to 150,000, and a small amount of low-molecular-weight products of 250 to 5000 was accumulated as residues during the growth of the isolate on PAA. In contrast, the other isolate Sphingomonas sp. KT-1 degraded only low-molecular-weight PAA below 5000. A mixed culturing of Pedobacter sp. KP-2 with Sphingomonas sp. KT-1 resulted in a complete degradation of PAA-P1 sample, but a small amount of low molecular weight components was accumulated during the degradation of highly branched PAA-P2 and PAA-P3 samples.

Abstract
We report a 63-year-old man with acute disseminated encephalomyelitis (ADEM), initially showing depression for one and a half months but subsequently meningoencephalitis followed by acute-onset myelopathy. Neuroradiological examinations of the brain demonstrated no focal lesion causative for his depression, while cerebrospinal fluid revealed elevated levels of inflammatory cytokines in parallel with disease activity. Because depression is usually a rare initial symptom for patients with ADEM, an increased production of inflammatory cytokines in the central nervous system as well as age-related alterations of immune response might have played an important role in the development of depression in this elderly patient.

Abstract
Experiments were performed to investigate the effects of acute and chronic intracerebroventricular (icv) morphine infusions via osmotic minipumps on long-term potentiation (LTP) in the lateral perforant path (LPP)-granule cell synapse of the rat dentate gyrus. Although significant antinociceptive activity was observed when morphine was infused (25 nmol/microl/h) for 30 min or 1 h, the activity was not observed in rats receiving morphine chronically for 72 h, and the tail-flick latency of this group was comparable to that of rats receiving saline. LTP induction was significantly attenuated after acute morphine infusion (1 h) in LPP-granule cell synapses of the dentate gyrus. In contrast, LTP induction was augmented after chronic morphine infusion for 72 h. Bath-perfused morphine augmented the baseline population spike (PS) amplitude in rats treated with saline, whereas it attenuated the LTP induced by chronic morphine infusion. Returning the LTP to the level of saline infusion after in vitro morphine perfusion suggests that enhancement of the LTP is a withdrawal-like phenomenon. These results suggest a difference between the effects of acute and chronic intracerebroventricular morphine infusions on synaptic plasticity in the LPP-granule cell synapses of the dentate gyrus.

Abstract
A homolog of the glucosamine-6-phosphate isomerase in the cellular slime mold Dictyostelium discoideum has been analyzed. The gene disruption mutant was arrested at the mound stage, demonstrating that the gene is important for development. The gene was expressed in vegetatively growing cells, silenced on starvation and expressed again in prestalk cells during the multicellular stages. The upstream region of the gene (1376 bp relative to ATG) was cloned and sequenced to study the transcription control mechanisms. Analysis of deletion mutants and a site-directed mutant indicated that the Myb-binding sequence (5'-AACTG-3') localized in the upstream region is important for gene expression. The results of gel-shift assays showed the presence of an Myb-related protein binding to the sequence at the growing phase and another protein binding to the sequence at developmental stages.

Abstract
In higher plants, the terminal step of L-ascorbic acid (AsA) biosynthesis is catalyzed by the enzyme L-galactono-1,4-lactone dehydrogenase (EC 1.3.2.3, GalLDH). We generated AsA-deficient transgenic tobacco BY-2 cell lines by antisense expression of the GalLDH cDNA that was amplified from BY-2 cells using PCR. Two transgenic cell-lines, AS1-1 and AS2-2, having a marked expression of antisense RNA were analyzed. Antisense suppression of GalLDH mRNA led to a significant decline in the GalLDH activity. The AsA levels in the transgenic cell lines were found to be 30% lower than the wild-type BY-2 cells. In synchronous cultures, division of AS1-1 and AS2-2 cells was restrained with a concomitant decrease in mitotic index that was probably due to a decline in AsA levels. The rate of cell growth was also found to be less than that of the wild-type cells. Interestingly, there was a significant phenotypic difference between the transgenic and wild-type cells. The calli of AS1-1 and AS2-2 appeared to be sticky and soft. Back extrusion method also showed that AsA-deficient BY-2 callus was rheologically soft. Furthermore, microscopic analysis revealed that AS1-1 and AS2-2 cells were abnormally slender, suggesting a potential for a significant and a uni-axial elongation. Thus, we observed that decline in the AsA levels has an adverse effect on the division, growth and structure of a plant cell.

Abstract
BACKGROUND AND AIM It has been suggested that dietary fat exacerbates intestinal inflammation. We investigated the effect of fatty acids on interleukin (IL)-8 production in a human intestinal epithelial cell line (Caco-2). METHODS The cells were cultured as monolayers on microporous membranes in culture inserts. Oleic acid (OA), capric acid (CA), docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) were applied to the apical compartment of Caco-2 cell monolayers. The concentration of IL-8 in the basolateral medium was measured by using enzyme-linked immunosorbent assay, and the expression of IL-8 mRNA was measured by using competitive reverse transcription--polymerase chain reaction. Protein kinase C inhibitors (GF109203X and calphostin C) and H-7 (a protein kinase inhibitor) were used to study the mechanisms by which IL-8 production is stimulated. RESULTS Both OA and CA enhanced IL-8 production (approximately fivefold), whereas DHA and EPA did not. Both OA and CA also enhanced IL-1-induced IL-8 production. The onset of OA-induced IL-8 production was delayed compared with that of CA-induced IL-8 production. Both OA and CA enhanced IL-8 mRNA expression (approximately fivefold) after 6 and 3 h, respectively. The protein kinase inhibitor (H-7) reduced both OA- and CA-induced IL-8 production by 88.0 and 85.9%, respectively. The protein kinase C inhibitors (GF109203X and calphostin C) reduced OA-induced IL-8 production by 29.3 and 54.5%, respectively, but showed no effect on CA-induced IL-8 production. CONCLUSIONS These findings suggest that not only OA but also CA stimulates IL-8 production in intestinal epithelial cells, and the mechanisms of action differ between OA and CA.

Abstract
We examined the effects of paeoniflorin on adenosine A1 receptor-mediated memory disturbance in the mouse passive avoidance test and inhibition of long-term potentiation (LTP) in the rat hippocampal CA1 region. The pretraining administration of the selective adenosine A1 receptor agonist N6-cyclopentyladenosine (CPA) significantly impaired the retention performance determined 24 h after the training test. The intraperitoneal injections of paeoniflorin and the adenosine A1 receptor antagonist 1,3-dipropyl-8-cyclopentylxanthine (DPCPX) significantly attenuated the deficit in retention performance caused by CPA. The in vitro studies revealed that adenosine (1 and 10 microM) dose dependently reduced both the population spike (PS) amplitudes and the tetanic stimulation-induced LTP in the hippocampus. DPCPX, at the concentration (0.1 microM) that had no effect on PS amplitudes or LTP induction, significantly reversed the suppressive effects of adenosine on both indices. Paeoniflorin also dose dependently reversed 10 microM adenosine-induced suppression of LTP but had no effect on PS reduced by adenosine. These results suggest that paeoniflorin ameliorates memory disruption mediated by adenosine A1 receptor and that modulation of adenosine-mediated inhibition of LTP in the hippocampus is implicated in its beneficial effect on learning and memory impairment in rodents.

Abstract
We report on an autopsy findings of a 92-year-old male with hemiballism-hemichorea associated with hyperglycemia and striatal hyperintensity on T1-weighed magnetic resonance imaging (MRI), a recently described clinicoradiological syndrome. Histologically, the putamen contralateral to the hemiballism consisted of multiple foci of recent infarcts associated with reactive astrocytic and interneuronal response. Substrate responsible for the MRI signal changes is still inconclusive.

Abstract
We report an elderly woman with multiple sclerosis who showed an extensive cavity formation in the midthoracic cord in addition to multiple abnormal intensity signals in the central nervous system on magnetic resonance imaging (MRI). The cavity decreased in size in response to corticosteroid therapy with an improvement in neurological symptoms. The autopsy demonstrated a slit-like cavity lined with no ependymal cells on the luminal surface in the lower cervical to midthoracic cord, with circumferentially distributed demyelinative lesions, leading to the pathological diagnosis of secondary syringomyelia. In this patient a limited necrosis formed in the spinal cord might have developed into a cavity formation with edematous fluid leading to subsequent episodes of neurological exacerbation.

Abstract
Alpha-Neup5Ac-(2-->6)-D-GalpNAc, the carbohydrate portion of sialyl-Tn epitope of the tumor-associated carbohydrate antigen, was prepared by a whole-cell reaction through the combination of recombinant Escherichia coli strains and Corynebacterium ammoniagenes. Two recombinant E. coli strains overexpressed the CMP-Neup5Ac biosynthetic genes and the alpha-(2-->6)-sialyltransferase gene of Photobacterium damsela. C. ammoniagenes contributed to the production of UTP from orotic acid. Alpha-Neup5Ac-(2-->6)-D-GalpNAc was accumulated at 87 mM (45 g/L) after a 25-h reaction starting from orotic acid, N-acetylneuraminic acid, and 2-acetamide-2-deoxy-D-galactose.

Abstract
We performed brain CT and single-photon emission computed tomography (SPECT) using N-isopropyl-p-[123I] iodoamphetamine (123I-IMP) as a tracer in the early stage of seven patients with Creutzfeldt-Jakob disease (CJD). In four of the patients, we determined absolute values of regional cerebral blood flow (rCBF) in the frontal, temporal, parietal and occipital lobes, thalamus and cerebellum using an autoradiographic method with a single blood sample. Brain CT demonstrated no abnormal findings other than a mild age-related atrophy in all patients except for one patient with a low-density area in the left cerebellar hemisphere due to an old hemorrhage, whereas SPECT revealed a decreased uptake of the tracer in various parts of the cerebral cortex of all patients, sometimes in an asymmetrical pattern. Absolute values of rCBF showed a significant decrease in all examined regions of the patients as against healthy controls (P<0.0001). In three patients, SPECT demonstrated a decreased uptake throughout the cerebral cortex on visual inspection, whereas absolute values of rCBF revealed an obvious decrease of the uptake also in the thalamus and cerebellum. These results suggest that SPECT with quantification of rCBF using 123I-IMP might be a sensitive and useful technique not only for detecting a focal metabolic dysfunction but also for diagnosis in the early stage of CJD.

Abstract
This study describes a potential effect of topical gentian violet on cutaneous infection and nasal carriage with methicillin-resistant Staphylococcus aureus (MRSA). 0.5% gentian violet was used in 28 cases of skin lesions once a day, while a 0.3% solution was applied on the nasal vestibules of nine cases twice a day. The period for eradication in the 28 skin cases was 9.1 +/- 6.0 days. It was 15.3 +/- 9.0 days for the nine nasal lesions. The minimal inhibitory concentration (MIC) of gentian violet against MRSA from the four isolated strains was 0.0225 +/- 0.0096 microg/mL. No adverse reactions occurred throughout the study. It is suggested that gentian violet may be potentially effective against MRSA.

Abstract
The effects of Uncaria tomentosa total alkaloid and its oxindole alkaloid components, uncarine E, uncarine C, mitraphylline, rhynchophylline and isorhynchophylline, on the impairment of retention performance caused by amnesic drugs were investigated using a step-down-type passive avoidance test in mice. In this test, the retention performance of animals treated with the amnesic and test drugs before training was assessed 24 h after training. Uncaria tomentosa total alkaloid (10-20 mg kg(-1), i.p.) and the alkaloid components (10-40 mg kg(-1), i.p.), as well as the muscarinic receptor agonist oxotremorine (0.01 mg kg(-1), i.p.), significantly attenuated the deficit in retention performance induced by the muscarinic receptor antagonist scopolamine (3 mg kg(-1), i.p.). The effective doses of uncarine C and mitraphylline were larger than those of other alkaloid components. Uncarine E (20 mg kg(-1), i.p.) also blocked the impairment of passive avoidance performance caused by the nicotinic receptor antagonist mecamylamine (15 mg kg(-1), i.p.) and the N-methyl-D-aspartate (NMDA) receptor antagonist (+/-)-3-(2-carboxypiperazin-4-yl)-propyl-1-phosphonic acid (CPP; 7.5 mg kg(-1), i.p.), but it failed to affect the deficit caused by the benzodiazepine receptor agonist diazepam (2 mg kg(-1), i.p.). Rhynchophylline significantly reduced the mecamylamine-induced deficit in passive avoidance behaviour, but it failed to attenuate the effects of CPP and diazepam. These results suggest that Uncaria tomentosa total alkaloids exert a beneficial effect on memory impairment induced by the dysfunction of cholinergic systems in the brain and that the effect of the total alkaloids is partly attributed to the oxindole alkaloids tested. Moreover, these findings raised the possibility that the glutamatergic systems are implicated in the anti-amnesic effect of uncarine E.

Abstract
This report concerns a 51-year-old right-handed man with Japanese encephalitis, showing left hemiplegia and left hemispatial neglect. On admission, he had a slight fever, mild consciousness disturbance, left hemiplegia, and left hemispatial neglect but no neck stiffness, headache nor nausea. He was treated on the basis of cerebral infarction, but his fever and consciousness disturbance worsened. We found pleocytosis (145/mm3) in the cerebrospinal fluid (CSF) and right thalamic edema on a brain CT scan obtained 4 days later. He was finally diagnosed as having Japanese encephalitis on the basis of an increase in anti-viral antibodies observed in paired CSF and serum samples. In the exacerbation phase, 123I-IMP single photon emission CT (SPECT) demonstrated a marked decrease in cerebral perfusion in the right hemisphere, while a brain MRI revealed irregular lesions localized the right thalamus (mainly posterior and medial parts), showing low intensity on T1-weighted and high intensity on T2-weighted images. In the recovery phase, asymmetrical perfusion was no longer observed on SPECT and the symptoms including the left hemispatial neglect had improved. These findings suggest that the left hemispatial neglect in this patient might been caused by the right thalamic lesion resulting in damage to the activating system of the right hemisphere. This case thus shows that acute onset of hemispatial neglect could be caused by cerebral encephalitis.

Abstract
This paper proves the non-existence of an optimal solution under the Liljas [Liljas, B. (1998). The demand for health with uncertainty and insurance. J. Health Econ., 17, 153-170] type of insurance. The reason for the non-existence is that the insurance induces the individual to increase his time input, relative to medical expenditure in the household production of health investment. Hence, it distorts the balance of inputs in the production of health investment. Moreover, it also distorts the household production for consumption goods through time constraints. Therefore, this paper proposes an alternative insurance that covers the time loss due to illness and has an optimal solution.

Abstract
Helicobacter pylori, which is a human pathogen associated with gastric and duodenal ulcer, has been shown to express human oncofetal antigens Lewis X and Lewis Y. Although the mammalian glycosyltransferases that synthesize these structures are well characterized, little is known about the corresponding bacterial enzymes. We report that a novel beta1,4-galactosyltransferase gene (HpgalT) involved in the biosynthesis of lipopolysaccharides in H. pylori has been cloned and expressed in Escherichia coli. The deduced amino acid sequence of the protein (HpGal-T) encoded by HpgalT consists of 274 residues with the calculated molecular mass of 31,731 Da, which does not show significant similarity to those of beta1,4-galactosyltransferases from mammalian sources and Neisseria It was confirmed that HpGal-T catalyzed the introduction of galactose from UDP-Gal in a beta1,4 linkage to accepting N-acetylglucosamine (GlcNAc) residues by means of high-performance anion-exchange chromatography with pulsed amperometric detection (HPAEC-PAD). When the E.coli cells which overexpressed HpgalT was coupled with the UDP-Gal production system, which consisted of recombinant E.coli cells overexpressing its UDP-Gal biosynthetic genes and Corynebacterium ammoniagenes, N-acetyllactosamine, a core structure of lipopolysaccharide of H.pylori, was efficiently produced from orotic acid, galactose, and GlcNAc.
