Abstract
e11584 Background: In woman with breast cancer, sentinel lymph node (SLN) biopsy (SLNB) provides staging information and a favorable effect on quality of life if the SLN does not have metastasis. While many reports already showed safety and reliability about SLNB for breast cancer patients in Western countries, few reports have published from Asian countries. Our purpose of this study is to prove the technical success, accuracy and safety of this method for Asian population. Methods: We did feasibility study of 183 patients from 2000 to 2002. After that, we evaluated detection rate, positive rate, axillary relapse rate in 1,000 consecutive patients who underwent sentinel lymph node biopsy for breast cancer at a single institute in Japan from 2002 to August 2008. In this series, both radioactive agent (technetium) and vital blue die (indigocarmine) were used to investigate the SLNs. Results: We could accurately predict SLNs in 994 (99.4%) of the 1,000 patients. The proportion of technical success was high regardless of surgeon's experience. Intraoperative frozen section histology showed that positive SLNs were found in 176 (17.7%) patients (13 micrometastasis and 163 macrometastasis). Defenitive histology found metastasis in 24 cases who defined as negative by the frozen section examination. 15 of 24 (62.5%) cases underwent delayed axillary lymph node dissection (ALND) after definitive histology. The histological concordance between frozen section and permanent sections of SLNs was 97.6%. Finally, 796 patients were followed up without ALND. With a median follow-up time of 3.5 years (0.5–5.2), axillary lymph node recurrence were occurred in 5 patients (5 of 796, 0.6%). The relapse time since SLNB ranged from 16 to 33 months. There were not any patients with allergic reactions. Conclusions: This is the report about observation study including more than 1,000 patients from Asian country. SLNB is seemed to be a safe and acceptably accurate method for Asian early breast cancer patients. No significant financial relationships to disclose.

Abstract
We report two cases of vasospastic angina associated with anaphylactic reaction caused by nonsteroidal anti-inflammatory drugs (NSAIDs). Both patients exhibited anaphylactic manifestations, such as general rash and urticaria, along with angina pectoris with electrocardiographic ST-segment elevations after suppository administration of diclofenac sodium or indomethacin, the most commonly used NSAIDs. Although these patients had normal coronary arteriograms, intracoronary administration of ergonovine or acetylcholine provoked diffuse coronary artery spasms accompanied by chest pain and ischemic ST-segment changes. It is therefore suggested that an allergic mechanism may be involved as a causative factor of the coronary artery spasm induced by NSAIDs.

Abstract
Papillomaviruses have been reported to be very difficult to grow in cell culture. Also, there are no descriptions of cell cultures from lesions of bovine cutaneous papillomatosis, with identification of different bovine papilloma virus (BPV) DNA sequences. In the present report, we describe primary cell cultures from samples of cutaneous lesions (warts). We investigated the simultaneous presence of different BPV DNA sequences, comparing the original lesion to different passages of the cell cultures and to peripheral blood. BPV 1, 2 and 4 DNA sequences were found in lesion samples, and respective cell cultures and peripheral blood, supporting our previous hypothesis of the possible activity of these sequences in different samples and now also showing how they can be maintained in different passages of cell cultures.

Abstract
ABSTRACT This report describes the first Brazilian equine herpesvirus type 1 (EHV-1) isolation from a single fatal equine herpes myeloencephalopathy case in a mare. The isolation of EHV-1 was confirmed from the first passage of cerebrospinal fluid (CSF) sample in Vero cells by PCR and virus neutralization assay. As virus isolation from CSF is unlikely to be successful, as has been shown in several case reports, this circumstantial evidence suggests that the neurological disease was caused by particularly neurovirulent strain of EHV-1.

Abstract
To assess the possible neurological basis of behavioral and psychological symptoms of dementia (BPSD), the relationships between BPSD and cognitive function were evaluated in 40 patients with Alzheimer's disease (AD). BPSD was assessed using the Behavioral Pathology in Alzheimer's Disease Frequency Weighted Severity Scale (BEHAVE-AD-FW) for behavioral symptoms and psychological symptoms separately, and cognitive function was also assessed using the Cognitive Abilities Screening Instrument (CASI). We found that only behavioral symptoms were associated with cognitive function based on the CASI total score and the score for the CASI attention domain. Administration of risperidone, an atypical anti-psychotic drug, for one month, improved the behavioral symptoms and the scores for the CASI attention and orientation domains. Our data suggest that BPSD in AD may reflect two largely independent pathophysiological processes: one associated with behavioral symptoms partly overlapping with attention, and the other associated with psychological symptoms predominantly unrelated to cognitive function.

Abstract
A 66-year-old right-handed man developed pure anarthria following pure word deafness. In addition to language disorders, his behavior gradually changed and finally included violence against his wife. Brain magnetic resonance imagings revealed atrophy of the left perisylvian area, which included the inferior half of the precentral gyrus and the upper portion of the superior temporal gyrus, consistent with frontotemporal dementia (FTD). It has been documented as either a disorder of expressive language or as an impaired understanding of word meaning. Unlike with pure anarthria, pure word deafness is not included in the clinical diagnostic current criteria for FTD. However, a large variety of language symptoms can appear in FTD according to the distribution of pathological changes in the frontotemporal cortices. This case suggests that pure word deafness could be a prodomal symptom of FTD.

Abstract
OBJECTIVE To study the ability of patients with semantic dementia to understand actions, in order to examine the contribution of semantic memory to action comprehension. METHODS The ability to comprehend symbolic and instrumental actions was assessed in 6 patients with semantic dementia and 10 healthy controls. The patients were also given the imitation test of meaningful and meaningless actions. RESULTS In all patients with semantic dementia, comprehension of both symbolic and instrumental actions was defective. The comprehension of symbolic actions was more impaired than that of instrumental actions. Their ability to imitate other's actions was well preserved. CONCLUSION This study showed that comprehension of action was impaired in semantic dementia, suggesting that semantic memory has an important role in comprehension of human action.

Abstract
BACKGROUND Severe alpha-1-antitrypsin deficiency (AATD), due to homozygosity for the protease inhibitor (Pi) Z allele, is a genetic risk factor for chronic obstructive pulmonary disease (COPD). In a previous study the sputum of severe AATD subjects with airflow obstruction showed a pattern of cellular inflammation similar to COPD patients. It is uncertain whether heterozygotes for the Z allele or intermediate deficiency (PiMZ) have an increased risk of developing COPD. METHODS Sputum cell counts and the supernatant level of the neutrophil chemoattractant interleukin (IL)-8 were investigated by sputum induction in 10 non-smoker asymptomatic PiMZ subjects with normal pulmonary function, 10 patients with stable COPD, and 10 age matched normal subjects. Data are expressed as mean (SD). RESULTS The mean (SD) number of neutrophils was significantly higher (p<0.01) in the sputum of PiMZ subjects (84.5 (22.2) x10(4)/ml) and patients with COPD (126.9 (18.8) x10(4)/ml) than in matched normal subjects (55.0 (8.7) x10(4)/ml). IL-8 levels were increased in PiMZ subjects (828.5 (490.6) ng/ml; median 1003.0 ng/ml; range 1260-100 ng/ml) and in COPD patients (882.5 (524.3) ng/ml; median 934.9 ng/ml; range 1506-258 mg/ml) compared with normal subjects (3.5 (0.5) ng/ml; median 3.5 ng/ml; range 4.5-2.5 ng/ml). There was a significant positive correlation between IL-8 supernatant concentration and neutrophil count in PiMZ subjects (p = 0.036; r = 0.66). An inverse correlation was observed between the percentage of neutrophils and forced expiratory volume in 1 second (% predicted) in patients with COPD (p = 0.04; r = -0.43). CONCLUSIONS These findings indicate that PiMZ subjects without airflow obstruction may have an IL-8 related neutrophilic inflammation in the airways, similar to stable COPD patients, suggesting an increased risk of developing pulmonary changes.

Abstract
The aim of this study was to identify relevant risk factors for occlusive lesions of the intracranial arteries in stroke-free population. The subjects of this study were 425 patients without a history of stroke or transient ischemic attack and without any abnormality on a neurological examination who consecutively visited a neurology clinic between January 1994 and June 2001 requesting medical evaluation for possible cerebrovascular diseases. Subjects included 245 men and 180 women ranging in age from 33 to 89 years (mean+/-SD=64.0+/-10.0 years). We performed cervical and intracranial magnetic resonance angiography (MRA) in all subjects. Using a validated rating scheme of MRA for occlusive lesions, we evaluated the degree of stenoses in the extracranial portion of the internal carotid artery (ICA) and the intracranial arteries including the intracranial portion of the ICA, middle cerebral artery (MCA) stem, intracranial portion of the vertebral artery (VA), and basilar artery (BA). More than 25% stenoses were regarded as significant lesions in this study. Multiple logistic regression analyses showed that significant and independent predictors for extracranial ICA lesions were age, hyperlipidemia, and ischemic heart disease (IHD), those for intracranial ICA lesions were age, hypertension, diabetes mellitus, and IHD, those for MCA lesions were age and hypertension, those for intracranial VA lesions were hyperlipidemia and IHD, and those for BA lesions were hypertension and diabetes mellitus. The present study suggested that atherosclerosis of the intracranial VA was related to hyperlipidemia and IHD as was the case for the extracranial carotid artery, whilst atherosclerosis of other sites of intracranial arteries was associated with hypertension and diabetes mellitus in stroke-free Japanese.

Abstract
To further provide scientific evidence before clinical application, the anti-tumor effects of apoptosis inducing nucleosides (AINs) released from CD57+HLA-DRbright natural suppressor (CD57.DR-NS) cell line on human gastric carcinoma (GCIY)-bearing severe combined immunodeficiency (SCID) mice were examined by monitoring tumor cell growth and change of body weight of mice. The results obtained evidenced that AINs strongly induced apoptosis in the tumor tissues in SCID mice with decrease of tumor size and without loss of body weight. We found that peak 5 and peak 6 (P5 and P6) components among six components (AINs) isolated from CD57.DR-NS cell cultures by high performance liquid chromatography (HPLC) are the most effective. The anti-tumor effective dosage of P5, P6 and their mixture, P5+P6, were obtained in dose-dependent manner. Thus, the most effective method of administration of AINs for tumor regression without exhaustion was established in the present study. Corresponding to the previous study that AINs could generate apoptosis in malignant cells while lacking the toxicity in normal cells, the results obtained in the present preclinical experiments suggested anti-tumor efficacy of AINs with possible refrainment from side-effects in clinical trials.

Abstract
Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) triggers apoptosis in tumor cells without toxicity to normal cells, but some recombinant versions of TRAIL caused hepatocyte death. We generated fully human monoclonal antibodies (mAbs) that bind specifically to TRAIL receptor 1 (TRAIL-R1) and TRAIL receptor 2 (TRAIL-R2), which mediate apoptosis signal when they ligate with TRAIL, to investigate the contribution of each receptor to induce tumor cell apoptosis and hepatocyte toxicity. All of mAbs to TRAIL-R1 and TRAIL-R2 induced cell death in several cancer cell lines susceptible to TRAIL but not in human umbilical vein endothelial cells in vitro. Both anti-TRAIL-R1 mAbs and anti-TRAIL-R2mAbs also caused cell death in hepatocytes. However, a subset of mAbs to TRAIL-R2, which was characterized by the TRAIL blocking activity, did not show strong hepatocyte toxicity. These results indicate that human normal hepatocytes are susceptible to both TRAIL-R1- and TRAIL-R2-mediated apoptosis signal.

Abstract
Progression of atherosclerosis at extracranial carotid and intracranial arteries in patients with ischemic heart disease (IHD) is not well defined. We carried out a 5-year longitudinal study with magnetic resonance angiography (MRA) of patients with IHD to assess the incidence of progression of atherosclerosis at extracranial carotid and intracranial arteries and to determine predictors of the progression. We previously performed carotid and intracranial MRA on 67 patients who had received selective coronary angiography for the clinical diagnosis of IHD. Of these 67 subjects, 41 patients gave informed consent to undergo MRA reexaminations to evaluate changes of extra- and intracranial arteries over a 5-year period. The degree of stenosis was divided into five grades depending on the narrowness of the arteries, i.e. normal, mild, moderate, severe and occluded. The average of follow-up period with MRA examination was 58.8 months. The progression of atherosclerosis, as defined as an increase of one grade of the stenosis rating, including both the exacerbation of pre-existing stenosis and the appearance of new stenotic lesions, were found in five patients (12.2%) for the cervical carotid artery and in only one patient (2.4%) for the intracranial artery. A multiple logistic regression analysis revealed that baseline carotid artery stenosis (P = 0.008), age (P = 0.047), and coronary events during the follow-up period (P = 0.048) were significant and independent predictors of progression of carotid atherosclerosis. In conclusion, our findings suggest that follow-up evaluation of the carotid artery is indicated for patients with IHD in whom carotid artery stenosis was detected on an initial examination. Further study is needed with larger numbers of patients to confirm these findings.

Abstract
We described a patient with bilateral striatal infarcts, in whom stereotyped and disinhibited behaviors were insidiously emerged over 2 years mimicking frontotemporal dementia (FTD). A positron emission tomography with 18-fluorodeoxy glucose showed a hypometabolism in the frontal lobes, basal ganglia, and thalami. The peculiar behavioral alterations remained unchanged for the following 7 years, suggesting that the disease is not degenerative but of vascular origin. A disruption of the fronto-subcortical circuits at the level of the striatum or the anterior thalamic peduncle is attributable to the FTD-like behavioral and cognitive syndrome.

Abstract
The CD57+HLA-DRbright-natural suppressor (57.DR-NS) cell line induced apoptosis in estrogen-non-responsive human breast carcinoma MDA-MB-435 cells by apoptosis-inducing nucleosides (AINs) released into the cultures. We obtained six active AINs isolated by high performance liquid chromatography (HPLC) from 57.DR-NS cell cultures. Each AIN isolated from 57.DR-NS cell cultures induced apoptosis in MDA-MB-435 cells. We found the occurrence of DNA strand breaks followed by the activation of caspase-3 during AIN-induced apoptosis in MDA-MB-435 cells. The data obtained here indicated that 57.DR-NS cells could induce apoptosis in MDA-MB-435 cells mediated by AINs through DNA strand breaks and activation of caspase-3. Furthermore, the administration of AINs into MDA-MB-435 tumor-bearing SCID mice culminated in strong suppression of tumor growth with no change of body weight of experimental mice suggesting no side effects of AINs.

Abstract
The role of the pulmonary alveolar macrophages (PAM) in the lung defense mechanism was evaluated in horses infected with equine hespesvirus-1 (EHV-1). Five adult horses were exposed to 10(6.6) TCID50 EHV-1 by intranasal instillation. Cytology of bronchoalveolar lavage (BAL) was performed using cytocentrifugation of samples and slides stained by Rosenfeld. Cell concentration was adjusted to 2<FONT FACE=Symbol>´</FONT>10(6) cells/ml, for the measurement of macrophage activity - spreading, phagocytosis of zymosan particles and release of hydrogen peroxide (H2O2). All animals were positive in virus isolation on the second, third and fifth days post-inoculation (DPI). Seroconversion was observed on the 14th DPI. Lymphocytosis was observed by BAL cytology on the 16th DPI. Measurement of macrophage activity demonstrated a marked increase in the spreading rate, on the 23rd and 30th DPI. Phagocytosis was decreased on the second DPI, and returned to levels similar to those observed before inoculation on the 23rd DPI. The amount of H2O2 released by PAM declined on day 2, but, by day 16, they returned to values similar to those observed before inoculation. The decline in PAM activity in the acute phase of disease is indirect evidence that these cells have an important role in lung defense mechanisms against this agent.
