Abstract
The role of neuroinflammation in the pathophysiology of migraines is increasingly being recognized, and cytokines, which are important endogenous substances involved in immune and inflammatory responses, have also received attention. This review examines the current literature on neuroinflammation in the pathogenesis of migraine. Elevated TNF-α, IL-1β, and IL-6 levels have been identified in non-invasive mouse models with cortical spreading depolarization (CSD). Various mouse models to induce migraine attack-like symptoms also demonstrated elevated inflammatory cytokines and findings suggesting differences between episodic and chronic migraines and between males and females. While studies on human blood during migraine attacks have reported no change in TNF-α levels and often inconsistent results for IL-1β and IL-6 levels, serial analysis of cytokines in jugular venous blood during migraine attacks revealed consistently increased IL-1β, IL-6, and TNF-α. In a study on the interictal period, researchers reported higher levels of TNF-α and IL-6 compared to controls and no change regarding IL-1β levels. Saliva-based tests suggest that IL-1β might be useful in discriminating against migraine. Patients with migraine may benefit from a cytokine perspective on the pathogenesis of migraine, as there have been several encouraging reports suggesting new therapeutic avenues.

Abstract
Pediatric mastocytosis is a relatively rare disorder and most commonly occurs as isolated cutaneous lesions. Although autism spectrum disorders have been reported to be associated with mastocytosis, no clear association between mastocytosis and motor and intellectual delay has been reported with the exception of the case that detected de novo monoallelic mutations in the GNB1 gene. Herein, we describe the case of a Japanese male pediatric patient aged two years and six months who had cutaneous mastocytosis accompanied by motor and intellectual delay without the presence of GNB1 mutation.

Abstract
Neuroinflammation has been implicated in the pathogenesis of West syndrome (WS). Inflammatory cytokines, including interleukin-1β(IL-1β), have been reported to be associated with epilepsy. However, the assessment of cytokine changes in humans is not always simple or deterministic. This study aimed to elucidate the immunological mechanism of WS. We examined the intracellular cytokine profiles of peripheral blood cells collected from 13 patients with WS, using flow cytometry, and measured their serum cytokine levels. These were compared with those of 10 age-matched controls. We found that the WS group had significantly higher percentages of inter IL-1β, interleukin-1 receptor antagonist (IL-1RA)-positive monocytes, and interferon gamma (IFN-γ) in their CD8+ T cells than the control group. Interestingly, the group with sequelae revealed significantly lower levels of intracellular IFN-γ and IL-6 in their CD8+ T and CD4+ T cells, respectively, than the group without sequelae. There was no correlation between the ratios of positive cells and the serum levels of a particular cytokine in the WS patients. These cytokines in the peripheral immune cells might be involved in the neuroinflammation of WS, even in the absence of infectious or immune disease. Overall, an immunological approach using flow cytometry analysis might be useful for immunological studies of epilepsy.

Abstract
Currently, migraine is treated mainly by targeting calcitonin gene-related peptides, although the efficacy of this method is limited and new treatment strategies are desired. Neuroinflammation has been implicated in the pathogenesis of migraine. In patients with migraine, peripheral levels of pro-inflammatory cytokines, such as interleukin-1β (IL-1β) and tumor necrosis factor-α, are known to be increased. Additionally, animal models of headache have demonstrated that immunological responses associated with cytokines are involved in the pathogenesis of migraine. Furthermore, these inflammatory mediators might alter the function of tight junctions in brain vascular endothelial cells in animal models, but not in human patients. Based on clinical findings showing elevated IL-1β, and experimental findings involving IL-1β and both the peripheral trigeminal ganglion and central trigeminal vascular pathways, regulation of the Il-1β/IL-1 receptor type 1 axis might lead to new treatments for migraine. However, the integrity of the blood-brain barrier is not expected to be affected during attacks in patients with migraine.

Abstract
INTRODUCTION To clarify the pathology of children with acute encephalopathy and other neurological disorders, the involvement of high-mobility group box 1 (HMGB1), which is a representative of danger-associated molecular patterns, and angiogenesis-related growth factors were investigated. PATIENTS AND METHODS Participants were 12 children with acute encephalopathy (influenza, rotavirus, and others), 7 with bacterial meningitis, and 6 with epilepsy disease (West syndrome). Twenty-four patients with non-central nervous system (CNS) infections as a control group were admitted to our hospital. We examined the levels of HMGB1, platelet-derived growth factor (PDGF), vascular endothelial growth factor (VEGF), and other cytokines in the serum and cerebrospinal fluid (CSF) of the subjects. RESULTS Serum and CSF HMGB1 levels were significantly higher in the encephalopathy and meningitis groups than in the West syndrome and control groups. CSF HMGB1 levels correlated with those of interleukin-6 and -8. CSF HMGB1 and VEGF levels were correlated, and PDGF showed a positive relationship. CONCLUSION HMGB1 and angiogenesis-related growth factors appear to play pivotal roles in the pathophysiology of CNS infections.

Abstract
In this study, we assessed circulating immune cells and plasma cytokine levels in 15 pediatric patients with drug-resistant epilepsy (DRE). DRE patients had a significantly higher percentage of CD14+ monocytes positive for IL-1β, IL-1 receptor antagonist, IL-6, and TNF-α than controls. Significantly higher intracellular levels of IFN-γ in CD4+ T cells and NK cells were also found in DRE patients. The level of IL-1β+ CD14+ monocytes correlated with seizure frequency, and intracellular levels of IFN-γ in NKT-like cells were negatively correlated with the duration of epilepsy. Peripheral immune cells might be involved in the pathogenesis of DRE.

Abstract
Complementary and integrative medicines (CIMs) are increasingly used as a preventive antimigraine therapy. In this review, we aimed to summarize the evidence for the efficacy and safety of eight CIMs (riboflavin, coenzyme Q10, magnesium, melatonin, polyunsaturated fatty acids, and combination therapy of feverfew, vitamin D, and ginkgolide B) in pediatric migraine prevention. The level of evidence for riboflavin was relatively high; it was investigated by many studies with five/seven studies demonstrating its efficacy. Five studies investigated the use of melatonin, with one reporting negative results. There was insufficient evidence on the effectiveness of coenzyme Q10, magnesium, and polyunsaturated fatty acids. Combination therapy showed positive potential; however, reports on the individual antimigraine effects of the CIMs were lacking. A definitive conclusion was not reached regarding the specific integrative drugs clinicians should choose for pediatric migraines, owing to low-quality evidence and a limited number of studies. Integrative medications are becoming more common for pediatric migraine prevention as they do not produce serious side effects, and underlying research data suggest their efficacy in preventing migraine. Additional studies are warranted to confirm the role of CIMs in treating patients with migraines.

Abstract
Several patients with beta-propeller protein-associated neurodegeneration (BPAN)/static encephalopathy with neurodegeneration in adulthood have been reported to present Rett syndrome (RTT)-like features. This report presents an individual with BPAN showing clinical features of RTT. Psychomotor delay and epilepsy onset were noted at 1 year, and regression began at 4 years. Screening of the methyl-CpG binding protein 2 (MECP2) did not show variants. At 22 years, basal ganglia iron deposits were found on magnetic resonance imaging (MRI), and the WD-domain repeat 45 gene (WDR45) variant was identified. Review of the literature showed that BPAN with RTT-like features is associated with more epileptic seizures and less deceleration of head growth, breathing irregularities, and cold extremities than classic RTT with MECP2 variants. These clinical presentations may provide clues for differentiating between these two disorders. However, both WDR45 and MECP2 should be screened in patients presenting a clinical picture of RTT without specific MRI findings of BPAN.

Abstract
BACKGROUND Riboflavin may prevent migraine episodes; however, there is limited evidence of its effectiveness in pediatric populations. This study investigated the effectiveness of riboflavin and clinical predictors of response in children with migraines. METHODS We retrospectively reviewed data from 68 Japanese children with migraines, of whom 52 also exhibited another type of headache. Patients received 10 or 40 mg/day of riboflavin. We evaluated the average migraine frequency per month as a baseline and after 3 months of riboflavin therapy to determine the effectiveness and clinical predictors of response. RESULTS The frequency of migraine episodes was significantly lower at 3 months than at baseline (median, [interquartile range], 5.2 (3-7) vs. 4.0 (2-5); p < 0.01). Twenty-five patients (36.7%) showed 50% or greater reduction in episode frequency (responders), while 18 (26.5%) showed a 25%-50% reduction. We compared responders (n = 25) and non-responders (n = 43) and found no significant differences in sex, familial history, riboflavin dose, migraine type (i.e., presence or absence of aura), age at headache onset, or age at consultation. However, non-responders were more likely to have co-morbid non-migraine headaches (odds ratio, 4.11; 95% confidence interval [CI], 1.27-13.33; p = 0.02); this variable was also significant in a multivariate analysis (adjusted odds ratio, 3.8; 95% CI, 1.16-12.6; p = 0.03). Of the co-morbid headache types, only tension headaches were significant (odds ratio, 0.176; 95% CI, 0.04-0.73; p = 0.013). No adverse effects of riboflavin were identified. CONCLUSIONS Low-dose riboflavin is safe and modestly effective for migraines in children. It may be especially beneficial for children without other co-morbid headache types.

Abstract
OBJECTIVE The present study aimed to determine whether granzymes are implicated in the pathogenesis of infection-associated acute encephalopathy (AE). METHODS We investigated granzyme and cytokine levels in the cerebrospinal fluid of patients with acute encephalopathy or complex febrile seizures (cFS). A total of 24 acute encephalopathy patients and 22 complex febrile seizures patients were included in the present study. Levels of granzymes A and B were measured using enzyme-linked immunosorbent assay, and levels of tumor necrosis factor α (TNF-α), interferon-γ (IFN-γ), interleukin 1β (IL-1β), IL-1 receptor antagonist (IL-1RA), IL-4, IL-6, IL-8, and IL-10 were assessed using the Bio-Plex suspension array system. RESULTS Cerebrospinal fluid levels of granzyme A were significantly higher, and those of TNF-α and IL-1RA were significantly lower in the AE group than in the cFS group; however, no significant differences in the levels of granzyme B, IFN-γ, IL-1β, IL-4, IL-6, IL-8, and IL-10 were observed between the 2 groups. In addition, no significant differences in granzyme A, granzyme B, or cytokine levels were observed between acute encephalopathy patients with and those without neurologic sequelae. CONCLUSIONS Our findings indicate the involvement of granzyme A in the pathogenesis of acute encephalopathy.

Abstract
BACKGROUND The establishment of a precise and rapid method to detect metastatic lymph nodes (LNs) is essential to perform less invasive surgery with reduced gastrectomy along with reduced lymph node dissection. We herein describe a novel imaging strategy to detect 5-aminolevulinic acid (5-ALA)-induced protoporphyrin IX (PpIX) fluorescence in excised LNs specifically with reduced effects of tissue autofluorescence based on photo-oxidation of PpIX. We applied the method in a clinical setting, and evaluated its feasibility. METHODS To reduce the unfavorable effect of autofluorescence, we focused on photo-oxidation of PpIX: Following light irradiation, PpIX changes into another substance, photo-protoporphyrin, via an oxidative process, which has a different spectral peak, at 675 nm, whereas PpIX has its spectral peak at 635 nm. Based on the unique spectral alteration, fluorescence spectral imaging before and after light irradiation and subsequent originally-developed image processing was performed. Following in vitro study, we applied this method to a total of 662 excised LNs obtained from 30 gastric cancer patients administered 5-ALA preoperatively. RESULTS Specific visualization of PpIX was achieved in in vitro study. The method allowed highly sensitive detection of metastatic LNs, with sensitivity of 91.9% and specificity of 90.8% in the in vivo clinical trial. Receiver operating characteristic analysis indicated high diagnostic accuracy, with the area under the curve of 0.926. CONCLUSIONS We established a highly sensitive and specific 5-ALA-induced fluorescence imaging method applicable in clinical settings. The novel method has a potential to become a useful tool for intraoperative rapid diagnosis of LN metastasis.

Abstract
BACKGROUND A patient's subjective response to neuroleptics is an important factor in pharmacotherapy of schizophrenia. In this study, we conducted an intervention to assess the effect of a questionnaire about neuroleptic side effects. We hypothesized that paying more attention to a patient's subjective distress associated with neuroleptic side effects would improve the patient's subjective response to neuroleptics. So we made a questionnaire about neuroleptic side effects, and used this questionnaire repeatedly in the usual clinical setting as an intervention. METHOD We administered this study to 210 outpatients who met the following criteria: (1) diagnosis of schizophrenia or schizoaffective disorder as defined by DSM-IV and (2) no worsening of symptoms in the past 6 months. The patients were divided into the intervention and the control groups. Patients of the intervention group filled out the questionnaire four times during 6 months and were given routine clinical care. Patients of the control group had routine clinical care only. The 10-item Drug Attitude Inventory (DAI-10) was used to evaluate the patients' subjective responses to neuroleptics. RESULTS After 6 months, the patients' subjective responses to neuroleptics assessed by the DAI-10 significantly improved in the intervention group (p<0.05 for within-group comparison). The most improved response was that the patients felt they were taking medications of their own free choice. CONCLUSION Paying more attention to the patient's subjective distress associated with neuroleptic side effects may have encouraged patients to participate in pharmacotherapy on their own initiative. This study suggests that our 19-item questionnaire is a useful tool to improve a patient's subjective response to neuroleptics.

Abstract
Abnormalities in gap junction function and Ca2+ dynamics are believed to be important factors in arrhythmogenesis after myocardial infarction. To elucidate the relationship between changes in Ca2+ dynamics and gap junctions, we analyzed by real-time in situ Ca2+ imaging of fluo-3 loaded whole hearts the spatiotemporal occurrence of Ca2+ waves and the localization of connexin43 (Cx43) at the border zone of myocardial infarcts induced in the rat by coronary ligation. At early time points (2-4 hours postligation), different regions of the left ventricle showed distinct changes in cytosolic free Ca2+ concentrations [Ca2+]i. While some cardiomyocytes of infarcted regions exhibited high levels of resting fluo-3 fluorescence, at border zones frequent Ca2+ waves were observed. Some of the waves were abolished by spontaneous Ca2+ transients and others were not. Intact myocardium apart from infarcted regions exhibited homogenous Ca2+ transients. Confocal imaging of Cx43 and actin filaments in the rat heart fixed 2 hours after coronary ligation revealed that Cx43 was markedly decreased in the area of myocyte necrosis with contraction bands and in the neighboring myocardium. These results suggest that abnormal expression and function of gap junctions could be associated with Ca2+ waves at the border zone of myocardial infarcts, possibly through Ca2+ overload.

Abstract
PURPOSE This study aims to assess the prognostic factors and optimal treatments for malignant germ cell tumors (MGCT) in childhood. METHODS Among 117 MGCT, the clinical features were analyzed. Regarding the histology, there were 89 embryonal carcinomas, 13 dysgerminomas, 4 choriocarcinomas, and 11 others. The prognostic factors and treatments were assessed based on the 5-year survival rate. RESULTS (1) Stage: 100% for stage I (n = 54), 75.0% for stage II (n = 4), 67.3% for stage III (n = 14), and 54.8% for stage IV (n = 33); Unknown: n = 12. (2) Primary site: 93.4% for the testis (n = 52), 86.7% for the ovary (n = 31), 56.9% for the sacrococcygeal (n = 21), and 60.6% for others (n = 12); unknown: n = 1. (3) Surgical intervention for primary tumor: 100% for stage I with a complete resection (n = 53), 78.4% for stage III, IV with a complete resection (n = 26), and 33.3% for stage III, IV with an incomplete resection (n = 21). (4) Type of chemotherapy for the stage III and IV: 83.9% for the PVB (cisplatin, vinblastin, bleomycin; n = 13), 66.7% for the VAC (vincristine, actinomycin D, cyclophosphamide; n = 6), and 47.1% for other regimens (n = 25). CONCLUSIONS An early stage, a diagnosis under 1 year of age and a primary site in the gonads were favorable prognosis factors, whereas histologic findings of choriocarcinoma and liver or lung metastasis were unfavorable. Radical complete resection alone is a sufficient treatment for localized MGCT. The PVB regimen is optimal chemotherapy for advanced MGCT; however, high-risk cases still may require more aggressive treatment.

Abstract
We report a case of acute lymphoblastic leukemia (ALL) presenting as severe jaundice. The patient, a 59-year-old man, was found to have abnormal liver function, including an elevated total bilirubin level (13.5 mg/dl) with hepatosplenomegaly, but no detectable lymphadenopathy. A liver biopsy and bone marrow examination revealed a lymphoid neoplasm. Pathologic features included invasion of an abnormal clone into the sinusoidal region of the liver, diffuse bone marrow involvement (41.6% of all nucleated cells) and splenomegaly. Small numbers of malignant cells were also detected in the peripheral blood. B-cell markers, such as terminal deoxynucleotidyl transferase (TdT), CD10, CD19, CD20 and HLA-DR were positive, and CD2, CD3, CD4, CD5, CD7, CD8, kappa, lambda, cytoplasmic mu and myeloperoxidase were negative. Cytogenetic analysis detected hyperdiploidy. In this case, a dose-attenuated CHOP regimen attained complete remission. To date, preferential infiltration to liver sinusoids has been noted in hepatosplenic gamma/delta T-cell lymphoma, other NK/T-cell malignancies, and some cases of hairy cell leukemia. Severe jaundice due to preferential infiltration of leukemic cells into liver sinusoids is rather uncommon as a presenting feature of ALL.

Abstract
OBJECTIVES To reveal the possible use of transrectal power Doppler imaging (PDI) of the prostate in the assessment of the microvascular density (MVD) of cancer lesions. METHODS In 22 patients with clinically organ-confined prostate cancer, PDI was performed before radical prostatectomy and the degree of vascularity of the cancer lesions as evaluated by PDI was compared with the MVD determined on the surgical specimens. The vascularity by PDI of each cancer lesion was graded on a scale of DS0 to DS2, according to the degree of Doppler signal accumulation. MVD was obtained using factor VIII immunohistochemistry. RESULTS The vascularity of the PDI of 46 cancer lesions categorized 23 (50%), 10 (22%), and 13 (28%) cancer lesions as DS0, DS1, and DS2, respectively. Significant differences were found in the MVD between DS0 (46.6 +/- 26.8) and DS2 (89.0 +/- 18.1, P <0.005) lesions and between DS1 (50.9 +/- 25.4) and DS2 (P <0.001) lesions. The MVD of 30 cancer lesions in 13 patients without neoadjuvant therapy was significantly higher than that of the 16 lesions in 9 patients with therapy (70.2 +/- 28.2 versus 39.5 +/- 23.9, P <0.001). In the 13 patients without neoadjuvant therapy, the MVD of the DS2 lesions (89.1 +/- 18.9) was significantly higher than that of the DS0 lesions (59.3 +/- 32.5, P <0.01) and DS1 lesions (55.9 +/- 20.9, P <0.005). CONCLUSIONS The semiquantitative assessment of Doppler flow signals using PDI appears to be of clinical value as an indicator of MVD.

Abstract
A 69-year-old woman was admitted with sudden chest pain and high fever. Electrocardiography showed negative T waves in the precordial leads. Subsequently, pleural and pericardial effusion developed, but the symptoms and signs subsided without specific therapy. On day 31, fever, left shoulder pain and pleural effusion reappeared. 67Ga scintigraphy showed abnormal uptake in the chest and left shoulder. Blasts were detected in the peripheral blood on day 44, and in the pleural effusion and bone marrow on day 45. The blasts were positive for Philadelphia chromosome, CD10, CD19, CD33, CD34 and IgH-chain rearrangement and negative for myeloperoxidase. The clinical picture of the preceding pleuropericarditis was that of viral or idiopathic origin, but its relationship with acute lymphoblastic leukemia was unclear. Inflammatory chemokines in the pleural space may have induced invasion of the leukemic cells.

Abstract
Using confocal microscopy and morphometry, we analyzed the expression of connexin26 (Cx26) and ZO-1 in rat cochlea during the postnatal period to elucidate spatiotemporal changes in gap junctions and tight junctions during auditory development. We also studied changes in these junctions in experimental endolymphatic hydrops in the guinea pig. In the adult rat cochlear lateral wall, Cx26 was detected in fibrocytes in the spiral ligament and in the basal cell layer of the stria vascularis, whereas ZO-1 was detected in the apical surfaces of marginal cells and in the basal cell layer. During postnatal development, Cx26 expression increased mainly in the spiral ligament, whereas ZO-1 expression increased in the basal cell layer. The morphometry of Cx26 showed a sigmoid time course with a rapid increase on postnatal day (PND) 14, whereas that of ZO-1 showed a marked increase on PND 7. In experimental endolymphatic hydrops, the expression of Cx26 significantly decreased, whereas there were no obvious changes in the expression of ZO-1. These results indicate that gap junctions and tight junctions in the cochlea increase in a different spatiotemporal manner during the development of auditory function and that gap junctions and tight junctions in the cochlea are differentially regulated in experimental endolymphatic hydrops.

Abstract
OBJECTIVES Tumor angiogenesis has been reported as a predictor for prognosis in patients with prostate cancer. The aim of this study was to determine the localization of one angiogenic factor, platelet-derived endothelial cell growth factor (PD-ECGF), in benign and malignant prostatic tissues and the correlation between PD-ECGF expression and microvessel density (MVD) in prostate cancer. METHODS Forty cases of prostate cancer, 3 cases of benign prostatic hyperplasia, and 5 young autopsy cases without prostatic disease were processed with immunohistochemistry, using an anti-PD-ECGF antibody and anti-factor VIII-related antigen antibody. The PD-ECGF expression intensity and MVD were evaluated in each case. RESULTS In the 40 cases with prostate cancer, the expression of PD-ECGF was noted in the stromal cells within cancer tissues in 80% of cases. Additionally, noncancerous glands next to cancer lesions were positive for PD-ECGF in 85% of cases. However, cancer cells were negative for PD-ECGF in all cases. In the 8 cases without cancer, both the prostatic glands and their surrounding stroma were positive for PD-ECGF only when they were accompanied by inflammation. There was a significant positive correlation (r = 0.636, P <0.001) between the intensity of PD-ECGF expression and MVD. MVD was significantly different when comparing the intensity of PD-ECGF expression of grade 0 versus grade 1 (P <0.05), grade 1 versus grade 2 (P <0.05), and grade 0 versus grade 2 (P <0.01). CONCLUSIONS This study suggested that PD-ECGF expression in the stromal cells within cancer tissues might play an important role in tumor angiogenesis in prostate cancer.

Abstract
OBJECTIVES To reveal the possible contribution of histological inflammation within the prostate to the abnormal elevation of serum prostate-specific antigen (PSA) levels in patients with needle biopsy negative for prostate cancer. METHODS We reviewed negative needle biopsy specimens obtained in 93 patients. The degree of acute and chronic inflammation as evaluated histologically was compared with serum PSA levels in conjunction with age and prostate volume. RESULTS Both age (P <0.01) and prostate volume (P <0.0001) correlated significantly with serum PSA levels and were significantly greater in patients with abnormal serum PSA levels (greater than 4.0 ng/mL) than in those with normal serum PSA levels (4.0 ng/mL or less) (P <0.01). The presence of histological inflammation within the prostate also correlated significantly with serum PSA levels. Multiple regression analysis demonstrated prostate volume to be the only independent determinant of serum PSA levels (P <0.01). In patients with a prostate volume larger than 25 mL, only prostate volume correlated significantly with serum PSA levels (P <0. 05). On the other hand, the degree of acute inflammation as represented by polymorphonuclear leukocyte infiltration was the only parameter correlating significantly with serum PSA levels (P <0.05) in patients with a prostate volume smaller than 25 mL. CONCLUSIONS Histologically defined acute inflammation within the prostate is a significant contributor to elevated serum PSA levels, especially in patients with small prostates. In the assessment of needle biopsy results negative for prostate cancer, it might be helpful to evaluate the degree of histological inflammation, especially in terms of the necessity of subsequent repeated biopsies.

Abstract
Although Ca(2+) waves in cardiac myocytes are regarded as arrhythmogenic substrates, their properties in the heart in situ are poorly understood. On the hypothesis that Ca(2+) waves in the heart behave diversely and some of them influence the cardiac function, we analyzed their incidence, propagation velocity, and intercellular propagation at the subepicardial myocardium of fluo 3-loaded rat whole hearts using real-time laser scanning confocal microscopy. We classified Ca(2+) waves into 3 types. In intact regions showing homogeneous Ca(2+) transients under sinus rhythm (2 mmol/L [Ca(2+)](o)), Ca(2+) waves did not occur. Under quiescence, the waves occurred sporadically (3.8 waves. min(-1) x cell(-1)), with a velocity of 84 microm/s, a decline half-time (t(1/2)) of 0.16 seconds, and rare intercellular propagation (propagation ratio <0.06) (sporadic wave). In contrast, in presumably Ca(2+)-overloaded regions showing higher fluorescent intensity (113% versus the intact regions), Ca(2+) waves occurred at 28 waves x min(-1) x cell(-1) under quiescence with a higher velocity (116 microm/s), longer decline time (t(1/2) = 0.41 second), and occasional intercellular propagation (propagation ratio = 0.23) (Ca(2+)-overloaded wave). In regions with much higher fluorescent intensity (124% versus the intact region), Ca(2+) waves occurred with a high incidence (133 waves x min(-1) x cell(-1)) and little intercellular propagation (agonal wave). We conclude that the spatiotemporal properties of Ca(2+) waves in the heart are diverse and modulated by the Ca(2+)-loading state. The sporadic waves would not affect cardiac function, but prevalent Ca(2+)-overloaded and agonal waves may induce contractile failure and arrhythmias.

Abstract
We investigated the photodynamic DNA strand-breaking activity of TiO(2). A solution of super-coiled pBR 322 DNA was irradiated with 5 J/cm(2) of UVA in the presence of TiO(2) and the products were analyzed by using gel electrophoresis. The ratio of open-circular DNA to super-coiled circular DNA was calculated from the resulting peak areas as a DNA strand-breaking index (SBI). The SBI of anatase-structure TiO(2) (band gap=3.23 eV) was greater than that of rutile structure (band gap=3.06 eV), and the level of SBI correlated with the photocatalytic activity for degradation of 2-propanol. The inhibitory effects of active oxygen scavengers, including DMSO, glutathione and histidine, on the DNA strand-breaking activity were examined. All of the scavengers except ascorbic acid showed inhibitory effects, as did several polyhydric alcohols including mannitol, a well-known hydroxyl radical scavenger. These results suggest that the photodynamic DNA strand-breaking activity of TiO(2) is due to active oxygen species, especially hydroxyl radicals. Polyhydric alcohols showed an inverse correlation between the inhibitory effect on DNA strand-breaking activity and the octanol/water partition coefficient (logP).

Abstract
At the border zone of myocardial infarcts, surviving cardiomyocytes achieve drastic remodeling of cell-cell and cell-extracellular matrix interactions. Spatiotemporal changes in these interactions are likely related to each other and possibly have significant impact on cardiac function. To elucidate the changes, we conducted experimental infarction in rats and performed 3-dimensional analysis of the localization of gap junctions (connexin43), desmosomes (desmoplakin), adherens junctions (cadherin), and integrins (beta(1)-integrin) by immunoconfocal microscopy. After myocardial infarction, changes in the distribution of gap junctions, desmosomes, and adherens junctions showed a similar but nonidentical tendency. In the early phase, gap junctions almost disappeared at stumps (longitudinal edges of cardiomyocytes facing the infarct), and, although desmosomes and adherens junctions decreased, they still remained. In the healing phase, at stumps, connexin43, desmoplakin, and cadherin were closely associated between multiple cell processes originating from a single cardiomyocyte. Electron microscopy confirmed the presence of junctional complexes between the cell processes. beta(1)-Integrin at the cell process increased during the formation of papillary myotendinous junction-like structures. Abnormal localization of connexin43 was often accompanied by desmoplakin and cadherin on lateral surfaces of surviving cardiomyocytes. These findings suggested that remodeling of gap junction distribution was closely linked to changes in desmosomes and adherens junctions and that temporary formation of intracellular junctional complexes was an element of the remodeling of cell-cell and cell-extracellular matrix interactions after myocardial infarction. Moreover, the remodeling of the intercalated disk region at the myocardial interface with area of scar tissues was associated with the acquisition of extracellular matrix and beta(1)-integrin.

Abstract
BACKGROUND Cardiomyocyte transplantation is an innovative strategy for the treatment of heart failure after myocardial infarction. Cell junctions show diverse temporal polarization toward intercalated disks during postnatal development and exhibit altered distribution in diseased hearts. To elucidate the formation of cell junctions between grafted and host cardiomyocytes at the border zone of myocardial infarction, the 3D distribution of cell junctions was examined using immunohistochemistry and confocal microscopy. METHODS AND RESULTS Neonatal cardiomyocytes obtained from 3-day-old rats by collagenase digestion and Percoll density centrifugation were injected into the border zones of infarction sites 10 days after coronary ligation in adult rats. At 4 to 14 days after transplantation, hearts were harvested and processed by immunohistochemistry. Antibodies against connexin43, desmoplakin, and cadherin were used to analyze the distribution of gap junctions, desmosomes, and adherens junctions, respectively. Grafted cardiomyocytes were identified by immunohistochemistry for alpha-smooth muscle actin. Grafted cardiomyocytes tended to align parallel to the host cardiomyocytes. Connexin43, desmoplakin, and cadherin were localized between grafted cardiomyocytes themselves and between grafted and host cardiomyocytes. Semiquantitative analysis revealed that all junctions showed increasing polarization to longitudinal cell termini, especially at the border of grafted and host cardiomyocytes, as time advanced from 4 to 7 days after transplantation. CONCLUSIONS These findings indicate that grafted cardiomyocytes foster electrical pathways with host counterparts through the gap junction and suggest that the environment in infarcted hearts could influence the localization of gap junctions, desmosomes, and adherens junctions.

Abstract
STUDY OBJECTIVE Data on the prevalence of myocarditis in children are limited. Autopsy studies have shown that myocarditis is often undiagnosed. We attempted to investigate the clinical features of asymptomatic myocarditis in four schoolchildren detected during a mass ECG screening in schoolchildren. DESIGN AND SETTING To evaluate asymptomatic myocarditis, we clinically examined 12 schoolchildren who were referred to Shiga University of Medical Science Hospital, Otsu, Japan, because of abnormal ST or T waves detected during ECG screening. None of the 12 children had experienced any episodes suggesting cardiac disease or Kawasaki disease. Cardiac function and myocardial viability were assessed by two-dimensional echocardiography (2-DE), thallium-201 (201Tl) myocardial scintigraphy, and cardiac catheterization. Endomyocardial biopsy specimens were examined histologically. PATIENTS Endomyocardial biopsy specimens revealed histologic evidence of myocarditis in 4 of the 12 children with abnormal ST or T waves. RESULTS Abnormal tracer perfusion was observed on 201Tl myocardial scintigrams in these four children, but the results of coronary arteriography were normal. 2-DE showed left ventricular hypokinesis in one child and left ventricular enlargement in one of the four children with histologic evidence of myocarditis. A second endomyocardial biopsy specimen was obtained in two of four children, showing persistent myocarditis in one child. CONCLUSIONS This type of screening program and indepth evaluation using 2-DE and 201Tl myocardial scintigraphy appear to be helpful in identifying children with myocarditis. The present histologic investigations suggested that even asymptomatic myocarditis might result in persistent heart damage.

Abstract
To assess the histologic reaction caused by biomaterial particles in different sizes around the bone-implant interface, we examined ultra-high molecular weight polyethylene (UHMWPE, average diameter of 11 microm), UHMWPE (99 microm), cobalt-chromium alloy (Co-Cr, 3.9 microm), stainless steel (SUS316L, 3.9 microm), alumina ceramics (3.9 microm), titanium alloy (Ti, 3.5 microm), Co-Cr (0.03 microm), and Ti (0.03 microm). After the longitudinal groove on a polymethylmethacrylate plug was filled with one type of the particles, the plug was inserted into the medullar canal of the distal end of rabbit femurs, and tissue block was resected 4 and 12 weeks after the insertion. Histiocytes were markedly accumulated around the particles of UHMWPE (11 microm), Co-Cr (3.9 microm), SUS316L (3.9 microm), Co-Cr (0.03 microm), and titanium alloy (0.03 microm). Around the UHMWPE particles (99 microm), a slight histiocytic reaction and bone formation were observed. Particles of alumina ceramics (3.9 microm) and titanium alloy (3.5 microm) which were in phagocytosable sizes also had few histiocytic reactions. Statistically, the material difference was more strongly related to the histiocyte reaction than to the particle size and calculated total surface area of particles. Our findings demonstrate that particles of different biomaterials and in different sizes induce different foreign-body histological reactions.

Abstract
We immunohistochemically and morphometrically examined the expression of gap junction protein connexin (Cx) in normal and crush-injured rat sciatic nerves using confocal laser scanning microscopy. Cx26 was localized in the perineurium and Cx43 was present in the perineurium and the epineurium, whereas Cx32 was confined to the paranodal regions of the nodes of Ranvier. Double labeling for connexins and laminin revealed that Cx43 was localized in multiple layers of the perineurium, whereas Cx26 was confined to the innermost layer. Double labeling for connexins and a tight junction protein, occludin, showed that occludin frequently coexisted with Cx43 but existed separately from Cx26 in the perineurium. After crush injury, the pattern of normal Cx32 expression was initially lost but recovered, whereas Cx43 rapidly appeared in the endoneurium and its expression was subsequently attenuated. Although crush injury produced no apparent alteration in Cx43 and occludin in the perineurium, a rapid increase and a subsequent decrease in the frequency of Cx26-positive spots during nerve regeneration were shown by morphometric analysis. These results indicate that Cx26, Cx32, and Cx43 are expressed differently in various types of cells in peripheral nerves and that their expressions are differentially regulated after injury. The expression of connexins and occludin in the perineurium suggests that perineurial cells are not uniform in type and that the regulation of gap junctions and tight junctions is closely related in the perineurium.

Abstract
In mammals, the biological clock (circadian oscillator) is situated in the suprachiasmatic nucleus (SCN), a small bilaterally paired structure just above the optic chiasm. Circadian rhythms of sleep-wakefulness and hormone release disappear when the SCN is destroyed, and transplantation of fetal or neonatal SCN into an arrhythmic host restores rhythmicity. There are several kinds of peptide-synthesizing neurons in the SCN, with vasoactive intestinal peptide, arginine vasopressin, and somatostatine neurons being most prominent. Those peptides and their mRNA show diurnal rhythmicity and may or may not be affected by light stimuli. Major neuronal inputs from retinal ganglion cells as well as other inputs such as those from the lateral geniculate nucleus and raphe nucleus are very important for entrainment and shift of circadian rhythms. In this review, we describe morphological and functional interactions between neurons and glial elements and their development. We also consider the expression of immediate-early genes in the SCN after light stimulation during subjective night and their role in the mechanism of signal transduction. The reciprocal interaction between the SCN and melatonin, which is synthesized in the pineal body under the influence of polysynaptic inputs from the SCN, is also considered. Finally, morphological and functional characteristics of clock genes, particularly mPers, which are considered to promote circadian rhythm, are reviewed.

Abstract
OBJECTIVE To discuss recent advances in the use of confocal microscopy to perform quantitative analysis of physiologic and pathologic intracellular events in the living organ. STUDY DESIGN We developed a new confocal microscope system equipped with a microlens-arrayed multipinhole scanning disc and water-immersion objective lenses. The confocal microscope enables us to quantitate nonhomogeneous changes in the three-dimensional intracellular calcium ion concentration in a living, whole heart. RESULTS The new system allows in situ quantitative imaging of the calcium wave in the living heart at a full video rate. Calcium waves propagating from cell to cell were frequently interrupted by calcium transients from spontaneous sinus rhythm, but low transparency of the living tissues and cell injury with laser light still remained unsolved. CONCLUSION The evolution of the confocal microscope with high spatial and temporal resolution renders the investigation of biologic phenomena even in the living organ.

Abstract
In order to study the subcellular heterogeneity of intracellular H+ concentration in reactive astrocytes, the pH in the nucleus and cytosol of cultured astrocytes was measured using a confocal laser scanning microscope (CLSM) and pH indicator dye, 5'(and 6')-carboxyseminaphthofluorescein (carboxy SNAFL-1). The change in intracellular pH was indexed by the fluorescence ratio (F535/F610) at an excitation wavelength of 514.5 nm. The in vitro fluorescence ratio increased as pH decreased. This ratio in the nucleus was significantly lower than that in the cytosol of astrocytes when perfused by HEPES-buffered Hanks' balanced salt solution (HHBSS) at pH 7.4. Acid stimulations of cells (pH 5.0) raised the fluorescence ratio in both nucleus and cytosol. However, the increase in the fluorescence ratio of the nucleus was less than that of cytosol. Treatment with a K+/H+ ionophore, nigericin (20 microM), reversibly nullified this cytosol-nucleus pH gradient. These findings suggest that a buffering mechanism(s) for maintaining of intracellular pH exists between the nucleus and cytosol, and a K+/H+ exchanger may act on the nuclear envelope to eventuate intranuclear pH maintenance in the living cells.

Abstract
In gastrointestinal epithelia, apoptosis has been thought to play a part in the shedding of postmitotic cells into the lumen. However, we have found that apoptosis more frequently in the generative cell (G) zone (the lower one third of the pit) than in the luminal zone (the upper one third of the pit) and the gland zone in the canine pyloric gland. To analyse the regulation of apoptotic cell death in each zone, we labelled S-phase cells by single and repeated injections of bromodeoxyuridine (BrdU) i.v. at intervals of 8 h. We found that 30% of apoptoses in the G zone were flash-labelled by BrdU and might derive from cells in or just after the S phase. The incidence of apoptosis and mitotic index did not change significantly after repeated injections of BrdU until the 49-h point, when the incidence of apoptosis increased and the mitotic index decreased significantly in the G zone, while the incidence of apoptosis decreased in the luminal zone. The BrdU-induced increase of apoptosis and cell-cycle arrest at the 49-h point may be caused by enhanced DNA mispairs that are elicited by incorporation of BrdU, in particular using the template of BrdU incorporated DNA. Apoptosis in the luminal zone may be down-regulated by reduced cell production in the G-zone.
