Abstract
UNLABELLED Following severe injury, biomineralization is disrupted and limited therapeutic options exist to correct these pathologic changes. This study utilized a clinically relevant murine model of polytrauma including a severe injury with concomitant musculoskeletal injuries to identify when bisphosphonate administration can prevent the paradoxical decrease of biomineralization in bone and increased biomineralization in soft tissues, yet not interfere with musculoskeletal repair. INTRODUCTION Systemic and intrinsic mechanisms in bone and soft tissues help promote biomineralization to the skeleton, while preventing it in soft tissues. However, severe injury can disrupt this homeostatic biomineralization tropism, leading to adverse patient outcomes due to a paradoxical decrease of biomineralization in bone and increased biomineralization in soft tissues. There remains a need for therapeutics that restore the natural tropism of biomineralization in severely injured patients. Bisphosphonates can elicit potent effects on biomineralization, though with variable impact on musculoskeletal repair. Thus, a critical clinical question remains as to the optimal time to initiate bisphosphonate therapy in patients following a polytrauma, in which bone and muscle are injured in combination with a severe injury, such as a burn. METHODS To test the hypothesis that the dichotomous effects of bisphosphonates are dependent upon the time of administration relative to the ongoing biomineralization in reparative bone and soft tissues, this study utilized murine models of isolated injury or polytrauma with a severe injury, in conjunction with sensitive, longitudinal measure of musculoskeletal repair. RESULTS This study demonstrated that if administered at the time of injury, bisphosphonates prevented severe injury-induced bone loss and soft tissue calcification, but did not interfere with bone repair or remodeling. However, if administered between 7 and 21 days post-injury, bisphosphonates temporally and spatially localized to sites of active biomineralization, leading to impaired fracture callus remodeling and permanence of soft tissue calcification. CONCLUSION There is a specific pharmacologic window following polytrauma that bisphosphonates can prevent the consequences of dysregulated biomineralization, yet not impair musculoskeletal regeneration.

Abstract
Abstract
Introduction
Chronic inflammation has been receiving considerable attention as an emerging risk factor for cardiovascular disease. In contrast, with the aging of the population, frailty has been also attracting a great deal of attention as the residual risk for cardiovascular disease. Although inflammation and frailty exacerbate each other and have an adverse effect on many diseases, the relationship between chronic inflammation and frailty and the impact of these combination on long-term prognosis in patients with acute coronary syndrome (ACS) are not elucidated.
Purpose
The aims of this study were to determine the association between chronic inflammation and frailty and its impact on long-term cardiovascular outcomes in patients with ACS.
Methods
A total of 482 consecutive ACS patients with obstructive coronary artery disease (age 66±12 years, male 81%) were enrolled in this observational study. We evaluated patients' gait speed as a measure of frailty before discharge. C-reactive protein (CRP) levels at 1 month after discharge were also evaluated as inflammation in the chronic phase. According to commonly used criteria of the residual inflammation (CRP>0.2 mg/dL) and the definition of the European Working Group for Sarcopenia (gait speed ≤0.8 m/sec), patients were stratified by 4 subgroups: low/high CRP with slow/normal gait speed. The primary endpoint was composite outcomes of cardiovascular death, myocardial infarction and ischemic stroke.
Results
While there was no significant association between CRP levels and gait speed in all patients, a significant negative association between two variables was observed in the high CRP group (Spearman's ρ = −0.31, p=0.001). During the median follow-up of 6 years, primary endpoints have occurred in 82 patients. Overall, event-free rates differed significantly among the 4 groups, demonstrating the lowest event-free rate in the patients with high CRP and slow gait speed (p<0.0001; Figure). In the multivariate analysis, high CRP (adjusted HR 1.99, 95% CI 1.14–3.46, p=0.02) and slow gait speed (adjusted HR 1.82, 95% CI 1.09–3.04, p=0.02) were independently and significantly associated with the primary endpoint. Moreover, the patients with both high CRP and slow gait speed had a 2.6-fold higher risk of cardiovascular events compared to others (adjusted HR 2.62, 95% CI 1.36–5.05, p=0.004).
Conclusion
In the patients with ACS, CRP levels and gait speed were negatively associated in the high CRP group. Chronic inflammation and frailty were both associated with poor prognosis in ACS and in particular, the combination of these factors was strongly associated with poor prognosis.

Abstract
Abstract
Introduction
Dyslipidemia, especially an increase in the low-density lipoprotein cholesterol (LDL-C) has been established as one of the most important risk factors for atherosclerotic cardiovascular diseases. In contrast, some recent studies have shown that the low LDL-C level was associated with short-term poor prognosis in patients with cardiovascular disease, and this is so-called “cholesterol paradox”. However, there is few data evaluating the effects on long-term outcome of “cholesterol paradox” in patients with acute coronary syndrome (ACS).
Purpose
The purpose of this study was to examine whether the low LDL-C level on admission affect long-term prognosis in patients with ACS.
Methods
A total of 434 ACS patients who survived to hospital discharge were enrolled in this study. All patients were statin-naïve on admission, and were received statin therapy after hospitalization. Patients were divided into the low LDL-C (≤114 mg/dl) and high LDL-C (>114 mg/dl) groups using the first tertile of the LDL-C level on admission. The primary endpoint was composite outcomes of all-cause death, myocardial infarction, ischemic stroke, hospitalization for congestive heart failure and unplanned revascularization.
Results
During a median follow-up period of 5.5 years, primary endpoint occurred in 117 patients. Overall, event-free rates differed significantly between the low and high LDL-C groups, demonstrating the lower event-free rate in patients with the low LDL-C group (38.9% in low LDL-C group versus 20.7% in high LDL-C group, p=0.0002; Figure). Even after adjustment for age, sex, body mass index, and various classical risk factors, the low LDL-C group was significantly at higher risk for primary composite outcomes compared to the high LDL-C group (adjusted hazard ratio 1.65, 95%-confidence interval 1.10–2.49, p=0.02).
Conclusion
In patients with ACS, the low LDL-C level on admission was significantly associated with long-term worse prognosis, regardless of statin therapy at discharge. In ACS patients with low LDL-C level, it might be necessary for elucidating the residual risk for secondary adverse event to improve their prognosis.

Abstract
OBJECTIVES The prognostic value of metabolic tumor volume (MTV) in locally advanced laryngeal or hypopharyngeal cancer is established in the setting of chemoradiotherapy, while it remains unknown in the setting of upfront total laryngectomy. MATERIALS AND METHODS We retrospectively analyzed 88 patients receiving total laryngectomy and neck dissection, using Cox regression models. RESULTS AND CONCLUSION Variables related to metastatic lymph node were associated with overall survival, whereas those related to primary tumor were not. In multivariable models, MTV of metastatic lymph nodes (N-MTV) as a continuous variable (Akaike's information criterion (AIC), 277.5) was equivalent to pathological nodal status (AIC, 278.2; P = 0.40), and superior to pathological nodal classification as an ordinal variable (AIC, 281.4; P < 0.05) in ability of predicting death. The risk of death was increased by 1.2-fold (95% confidence interval (CI), 1.0-1.4; P = 0.03) every 10-ml increment of N-MTV, while patients with pN+ disease were at a higher risk of death by 2.9-fold (95% CI, 1.0-12.2; P < 0.05) compared with patients with pN0 disease. Using recursive partitioning analysis (RPA), we classified the patients as having a low, intermediate, or high risk of death on the basis of N-MTV and extranodal extension (ENE). This RPA classification system exhibited greater concordance with overall survival than the classification considering pathological nodal status and ENE (AIC, 275.8 versus 281.4; P = 0.02). In the setting of upfront total laryngectomy, N-MTV is a critical predictor of mortality. A staging system in which N-MTV is incorporated may better inform adjuvant treatment decisions.

Abstract
When a tumor invades the muscularis mucosa and submucosal layer (T1a-MM and T1b in Japan), esophageal squamous cell cancer poses 10-50% risk of lymph node metastasis. By this stage of esophageal cancer, surgery, although very invasive, is the standard radical therapy for the patients. Endoscopic mucosal resection (EMR) is the absolutely curable treatment for cancer in the superficial mucosal layer. Because of its minimal invasiveness, the indications of EMR may be expanded to include the treatment of T1a-MM and T1b esophageal carcinoma. To date, the clinical outcomes of EMR for T1a-MM and T1b patients have not been fully elucidated. Here, the retrospective analysis of the clinical outcomes is reported. Between January 1994 and December 2007, 247 patients underwent EMR at Kanagawa Cancer Center. Of these individuals, 44 patients with 44 lesions fulfilled the following criteria: (i) extended EMR treatment for clinical T1a-MM and T1b tumor; (ii) diagnosis of clinical N0M0; and (iii) follow up for at least 1 year, and negative vertical margin. These patients were reviewed for their clinical features and outcomes. Statistical analyses were performed by the Kaplan-Meier methods, the Chi-square test, and the Cox proportional hazard model. P-value of <0.05 was considered statistically significant. The data were analyzed in February 2009. Based on the informed consent and their general health conditions, 44 patients decided the following treatments immediately after the EMR: 2 underwent surgery, 1 underwent adjuvant chemotherapy, and 41 selected follow up without any additional therapy. Of the 41 patients, 20 selected this course by choice, 12 because of severe concurrent diseases, 2 because of poor performance status, and 7 because of other multiple primary cancers. Twelve patients died; two were cause specific (4.5%), eight from multiple primary cancers, one from severe concurrent diseases, and one from unknown causes. No critical complications were noted. Median follow-up time was 51 months (12-126). Five patients ultimately developed lymph node metastasis. One patient with adjuvant chemotherapy required surgery, and another was treated with chemotherapy whose subsequent death was cause specific. The other three patients received chemoradiotherapy and have not shown cause-specific death. Overall and cause-specific survival rates at 5 years were 67.3% and 91.8%, respectively. Among 41 patients treated by EMR alone, only one died from primary esophageal cancer (2.4%), and overall and cause-specific survival rates at 5 years were 75.6% and 97.6%, respectively. Multivariate analysis revealed that severe concurrent diseases including multiple primary cancers and the administration of 5-fluorouracil-based chemotherapy for multiple primary cancers significantly influenced survival (P= 0.025, hazard ratio [HR] 13.1 [95% confidence interval 1.5-114]) and (P= 0.037, HR 0.213 [95% confidence interval 0.05-0.914]), respectively. Eight and six patients developed metachronous esophageal squamous cell cancer and local recurrence, respectively. With the exception of one patient, they could be retreated endoscopically. EMR is a reasonable option for the patients with T1a-MM and T1b esophageal carcinoma without clinical metastasis, especially for the individuals with severe concurrent diseases. The prognostic factors for the benefit of EMR in such cases should be further examined.

Abstract
Transurethral vaporization of the prostate in saline (TURisV) is an innovative endoscopic surgical modality for the treatment of benign prostatic hyperplasia (BPH) that vaporizes prostate tissue using a uniquely designed mushroom electrode. TURisV promises instant hemostatic tissue ablation under saline irrigation and offers clinical advantages for endoscopic BPH operations. From July 2008 to February 2009, TURisV was performed in 17 cases with clinically significant BPH. Median operation time was 127.0 min and median volume of vaporized prostate tissue was 41.1 g. Median International Prostate Symptom Score improved from 20 to 4 after 12 months. Median maximum flow rate increased from 5.3 mL/s to 13.8 mL/s after 12 months. Postoperative median residual urine improved from 48.0 mL to 7.0 mL after 12 months. No changes in hemoglobin or electrolyte levels were seen postoperatively. Our results suggest that TURisV is a safe and efficacious treatment for BPH.

Abstract
BACKGROUND While cumulative lifetime sun exposure is well recognized as having an important role in the progression of facial wrinkling, the role of facial expression has largely been overlooked, in part due to the lack of comprehensive longitudinal data on the change in both expression lines and persistent wrinkles with age. OBJECTIVES To track the detailed pattern of facial wrinkling in the same group of people over several years and to verify that expression lines evolve into persistent wrinkles. In addition, to identify factors predictive of a faster or slower rate of wrinkling. METHODS Standardized images were captured at baseline and at 8 years of 122 women (ages 10-72 years, skin types I-VI) with and without a smiling expression. The wrinkle pattern with expression at baseline was compared with the pattern without expression at 8 years. Severity of facial wrinkling was quantified using computer-based image analysis. Skin colour, hydration, sebum and pH were measured at baseline. A structured questionnaire captured demographic and lifestyle data at baseline and at 8 years. RESULTS Each subject's unique pattern of persistent facial wrinkling observed without expression at year 8 was predicted by the pattern of lines observed with a smiling expression at baseline. Having a drier, more alkaline stratum corneum, a lighter complexion, being middle-aged (40s) or becoming menopausal were associated with faster persistent wrinkling. CONCLUSIONS Repeated skin flexure during facial expression causes persistent wrinkles. The pattern of expression lines predicts the pattern of future persistent wrinkles. Certain intrinsic and extrinsic factors are not causative, but influence the rate, of facial wrinkling.

Abstract
It was recently discovered that the photoreceptor cryptochrome is involved in mediating magnetosensitive entrainment of the internal clock of fruit flies.1 This discovery follows other recent studies implicating a role of cryptochrome in mediating magnetic sensitivity in orientation responses of fruit flies2,3 and growth responses of plants.4 Such widespread use of the same molecule for mediating magnetic sensitivity might suggest that cryptochrome is in some way optimal for detecting the magnetic field of the earth and that the magnetoreception function cannot be easily taken over by other molecules. This raises the question what properties might set cryptochromes apart from other molecules in terms of their ability to detect the geomagnetic field. Here, we will discuss possible answers to this question. We will first review the likely biophysical mechanism by which magnetic fields can be detected by a photoreceptor and discuss what constitutes an optimal photo-magneto-receptor. We will then discuss in how far cryptochrome matches the profile of an optimal molecule and what further steps are required for more conclusive answers.

Abstract
e15569 Background: When a tumor invades to the muscularis mucosa or submucosal layer (T1a-MM or T1b, in Japan), cSt I esophageal cancer(EC) has 10–50%. risk of lymph node metastasis (LNM). Surgery, though very invasive, is the standard radical therapy for the patients(pts.) with such stage EC. Endoscopic mucosal resection (EMR), which conserves the esophagus, is a minimally invasive and attractive therapeutic modality for such pts. However, the clinical outcomes of EMR for these pts. have been not fully elucidated. Methods: We conducted retrospective analysis of the clinical courses of 44 pts. who underwent EMR for newly diagnosed T1a-MM or T1bcN0M0 EC between 1994 and 2007at our hospital, and who could be followed up for at least 1 year. Statistical analysis was performed by the Kaplan-Meier methods and the Cox proportional hazard model. Results: Patients decided on the following treatments immediately after EMR based on informed consent and their general condition; 2 underwent surgery, one underwent prophylactic chemotherapy(CHT) and 41 selected follow-up without any additional therapy. Of the 41, 20 selected this course by choice, 12 because of severe concurrent disease; 2 because of poor performance status and 7 because of other multiple primary cancers (MPCs). Twelve pts. died; 2 were cause specific; (4.5%), 8 from MPCs and, 2 from unknown causes. Median age was 67 years old (range 53–80), and 5 were female. No critical comlications were noted. Median follow-up time was 1542days (375–3786). 5 developed LNM. One with prophylactic CHT, was followed by surgery, and another was followed by CHT, who showed cause specific deaths later. Other 3 pts. followed by chemoradiotherapy, did not show cause specific death. Overall and cause specific survival rates at 5 years were 67.3% and 91.8%, respectively. Multivariate analysis revealed that either severe concurrent disease or MPCs significanctly influenced survival (p=0.041, HR 5.437(95%CI 1.073–25.542)). 8 and 6 pts. developed metachronous EC and local recurrence, respectively. Apart from one, they could be retreated endoscopicaly. Conclusions: EMR is a very useful therapeutic modality for cSt I EC, not only for local control but also as a clinically sufficient treatment; especially in pts. with severe concurrent disease.

Abstract
Vasopressin (AVP) plays an important role in anxiety-related and social behaviors. Single-prolonged stress (SPS) has been established as an animal acute severe stress model and has been shown to induce a lower adrenocorticotropic hormone (ACTH) response upon cortisol challenge. Here, we show results from immunoassays for AVP, ACTH, and corticosterone (CORT), and in situ hybridizations for AVP mRNA performed 7 days after SPS exposure. Immunofluorescence for AVP was also performed during the 7-day period following SPS exposure and after an additional forced swimming stress paradigm. We observed that the plasma concentrations of AVP, ACTH, and CORT were not altered by SPS; ACTH content in the pituitary and AVP mRNA expression in the supraoptic nucleus (SON) were significantly reduced by SPS. During the 7-day period following SPS, the intensity of immunoreactivity, the size of the soma, and the immunoreactive optical density of the dendrites of AVP neurons in the SON all increased. An apparent reduction in the intensity of AVP immunoreactivity was observed in the SON at 4 h after additional stress. Additional forced swimming led to a rapid increase in the dendritic AVP content only in the controls and not in the SPS-treated rats. These findings suggest that AVP is a potential biomarker for past exposure to severe stress and that alterations in AVP may affect the development of pathogenesis in stress-related disorders.

Abstract
15105 Background: Therapy for early gastric cancer (GC) varies according to risk of LNM. When the possibility of LNM is very remote, the primary lesion can be resected by the minimally invasive endoscopic surgery only. Therefore, useful parameters predicting LNM are needed. E-cadherin, a component of the cell-cell junctional structure, is known to correlate with GC. In vitro, previous studies elucidated that disorders of cell-cell junction increased the potential of metastasis, and that phosphorylation of β-catenin by c-erbB-2 induced loss of membranous E-cadherin and β-catenin, resulting in junctional structure disorders. Here we evaluated significance of analysis of these molecules in LNM prediction in early GC. Methods: The clinicopathological features and immunohistochemical expressions of E-cadherin, β-catenin, and c-erbB-2 in the primary lesion were studied in 28 patients (LNM +ve group: 14, LNM1 -ve group: 14) selected from 272 patients who underwent radical surgery for early GC between April 2000 to March 2004 at our hospital. All the patients consented to use of their stomach tissues for the clinical study afterwards. Statistical analysis was performed by t-test or χ2 test. Results: The clinicopathological features showed no significant differences between both groups. Loss of the membranous E-cadherin was noticed in 12 (85%) of the 14 LNM +ve patients, and in 8 (57%) of the 14 LNM -ve patients (p=0.209). This result was more remarkable in the intestinal type GC as the corresponding figures were 83% (5 of 6 ) and 16% (1 of 6) (p=0.083), respectively. Loss of the membranous β-catenin also showed a remarkable similar trend in the intestinal type GC, and the corresponding figures were 100% (6 of 6) and 50% (3 of 6) (p=0.182), respectively. Two patients showed over-expression of c-erbB2 and nuclear accumulation of β-catenin, and both had intestinal type GC with LNM. Conclusions: These results suggested that the same molecular signal pathway - as in vitro - including E-cadherin, β-catenin, and c-erbB2 induced LNM in early GC (intestinal type). We concluded that analysis of the expressions of these molecules is useful for not only LNM prediction but also determination of the therapeutic modality especially in intestinal type early GC.

Abstract
This chapter summarizes our present knowledge about the master clock of the fruit fly at the neuronal level. The clock is organized in distinct groups of interconnected pacemaker neurons with different functions. All of these neurons appear to communicate with one another in order to produce the species-specific activity rhythm, which is organized in morning (M) and evening (E) activity bouts. These two activity components are differentially influenced by distinct groups of pacemaker neurons reminiscent of the Pittendrigh-Daan dual oscillator model. In the original work (Grima et al. 2004; Stoleru et al. 2004), the ventrolateral (LN(v)) and dorsolateral (LN(d)) plus some dorsal groups (DN) of clock neurons have been defined as M and E cells, respectively. We further specify that the clock neurons belong to the M and E oscillators and define a more complex picture of the Drosophila brain clock.

Abstract
4088 Background: Radical surgery for esophageal cancer is very invasive. Endoscopic mucosal resection (EMR), which conserves the esophagus, is a minimally invasive and attractive therapeutic modality for early stage esophageal cancer. However, when the tumor reaches the deep mucosal or submucosal layer (“T1b” according to TNM classification), the incidence of lymph node metastasis (LNM) increases up to 10–50%. Therefore, the indications of EMR have to be clarified. Methods: Retrospective analysis was performed regarding the clinical course of 41 patients who were diagnosed as having cT1bN0M0 esophageal cancer and underwent EMR between 1994 and 2004 at our hospital. Statistical analysis was performed by the log-rank and Kaplan-Meier methods. Results: Thirty nine patients were selected and followed up without any additional therapy after obtaining written informed consent. Twenty patients (51%) had multiple primary cancers, 10 died, and 29 are still alive. MST of the dead patients was 22 months, and 7 of them (70%) died of advanced multiple primary cancers, while death was cause specific in only one case (due to LNM). The survival curves showed no significant differences between the patients with early multiple primary cancers and those without multiple cancers patients (MST = 72 months, p < 0.7784). In most of the dead patients and 23 of the surviving patients, the local lesion was well controlled without any recurrence. Conclusions: Many patients with early esophageal cancer who underwent EMR tended to die of multiple primary cancers. When the patient had early multiple primary cancers, the prognosis was not different from those without such cancer and the local lesion was well controlled. We concluded that EMR is a very useful therapeutic modality for local control as it is minimally invasive, especially in patients with multiple primary cancers.

Abstract
Fungal endocarditis caused by Candida species is associated with high morbidity and mortality. A combination of surgical resection and antifungal drug therapy is the golden standard for treatment. We reported a case of fungal endocarditis due to Candida lusitaniae found at onset of lower limb acute aortic occlusion cured by emergency operation. This case suggests that Candida endocariditis can be managed medically with antifungal drug therapy in life time.

Abstract
Pseudoankylosis of the mandible after intracranial surgical procedure has been widely reported, and is usually caused by fibrosis of the temporal muscle as a result of injury during the operation. We present an unusual case of mandibular pseudoankylosis as a result of methyl methacrylate-induced aseptic inflammatory cicatricial contracture of the temporal muscle after cranioplasty.

Abstract
OBJECTIVE The purpose of this study was to evaluate various oral antimicrobial agent levels in tooth extraction sites. STUDY DESIGN The concentration of dental alveolar blood in extraction wounds after the oral administration of talampicillin (500 mg), cefaclor (500 mg), cefteram pivoxil (200 mg), cefuroxime axetil (250 mg), cefdinir (200 mg), and ofloxacin (100 mg) was determined in 338 patients and was assessed on the basis of its antimicrobial activity against Streptococcus isolated in odontogenic infections. RESULTS The percentage of patients whose concentrations exceeded the minimum inhibitory concentration for 90% of Streptococcus was 62.5% to 100% for talampicillin at 30 to 360 minutes, 0% to 12.5% for cefaclor at 30 to 360 minutes, 18.2% to 100% for cefteram pivoxil at 30 to 480 minutes, 50% to 100% for cefuroxime axetil at 30 to 480 minutes, 0% to 50% for cefdinir at 16 to 290 minutes, and 0% to 40% for ofloxacin at 30 to 480 minutes. CONCLUSION These results indicate that talampicillin, cefteram pivoxil, and cefuroxime axetil have minimum inhibitory concentration levels for 90% of Streptococcus in tooth sockets.

Abstract
A clinical statistical analysis on 65 patients with 68 testicular germ cell tumors was performed. Thirty-six testes (53.7%) had seminomas and the remainder non-seminomatous germ cell testicular tumors (NSGCTTs). Of the seminomas, 31 (88.6%) were in stage I and the others showed distant metastases at presentation. Of the 32 NSGCTTs, 22 (68.8%) were in stage I. The average ages of the patients with seminomas and NSGCTTs were 40.4 and 29.9 years, respectively. Thirty-nine patients (60.0%) had tumors on the right side, 23 (35.4%) on the left and 3 (4.6%) in both testes. Five patients had a past history of cryptorchidism. Chief complaints in 49 patients (73.1%) were a painless scrotal mass. The interval from clinical onset to presentation was longer in seminoma patients than in NSGCTT patients (10.9 months on average versus 3.4 months). Immunosuppressive acidic protein (IAP) was a useful diagnostic tumor marker as well as alpha-feto protein (AFP), beta-human chorionic gonadotropin (beta-hCG) and lactic dehydrogenase (LDH). We adopted a surveillance policy in more than half of the stage I patients and obtained acceptable results. In the remaining cases, therapies including combination chemotherapy, radiation and salvage operation were performed after orchiectomy. The three-year survival rate was 98.0, 100.0 and 26.7%, for stage I, II and III patients respectively.

Abstract
The clinical efficacy of long-term roxithromycin treatment was examined objectively in nine patients with chronic diffuse sclerosing osteomyelitis of the mandible. Roxithromycin was administered orally at a dose of 300 mg/day for between 68 days and 66 months. In seven of the nine cases (77.8%), the symptoms disappeared 1-12 months after the start of therapy. Radiography showed that osteolytic changes (evident from 'moth-eaten' appearance of bone) had improved but that osteosclerosis had persisted or become more predominant by the end of therapy. Therefore, the optimum duration of treatment should be decided according to the amelioration of symptoms along with the disappearance of osteolytic findings in radiographs. Diarrhoea and stomach discomfort occurred in one case, and liver dysfunction in another, but these adverse reactions were relatively mild. The mechanism of action of roxithromycin in this study is not yet fully understood, but our results indicate that long-term roxithromycin treatment may be useful for diffuse sclerosing osteomyelitis of the mandible and should be attempted before surgical treatment is considered.

Abstract
To clarify the similarities of poliovirus infection in cynomolgus monkeys and transgenic mice bearing the poliovirus receptor, TgPVR21, we compared the pathological changes of these animals following intraspinal inoculation of two strains of poliovirus type 3 using immunohistochemical detection of the capsid antigen. All of the monkeys inoculated with 10(6) TCID(50) viruses showed flaccid paralysis 2 or 3 days post-inoculation (p.i.). TgPVR21 mice showed paralysis starting from 2 to 3 days p.i. Histologically, neurons having pyknotic nuclei and eosinophilic cytoplasm and neuronophagia were characteristically observed in both animals, but central chromatolysis was not observed in infected TgPVR21. The median lesion scores in the monkeys and TgPVR21 were well correlated, though the distribution of poliovirus-infected lesions in the central nervous system was different. In both animals the motor neurons and the brainstem nuclei responsible for flaccid paralysis were infected by the virus, while the cerebral cortex and thalamus were infected in the monkeys but not in TgPVR21. These results confirmed the reliability of neurovirulence tests using TgPVR21 as a substitute for monkeys, in respect to the spinal and brainstem lesions of poliovirus type 3.

Abstract
Galectin-3, a beta-galactoside-binding protein, is highly expressed in thyroid papillary carcinomas, while functional relevance of galectin-3 overexpression to the malignant phenotype remains elusive. In the present study we transfected galectin-3 antisense cDNA into the human thyroid papillary carcinoma cell line NPA which expresses an innately high level of galectin-3, and examined the effect of antisense inhibition of galectin-3 expression on the transformed phenotype. There was no difference in anchorage-dependent growth between the antisense clones and either the control or parental clones. In contrast, anchorage-independent growth and saturation density of the antisense clones were significantly suppressed compared to those of either the control or parental clones. These results demonstrate that overexpression of galectin-3 in thyroid papillary carcinoma cells is necessary for the maintenance of transformed phenotype, and suggest galectin-3 as a potential target for therapeutic interventions in the future.

Abstract
PURPOSE The value of apparent accommodation varies with methods of measurement. To discuss the details of apparent accommodation, it is appropriate to measure it with the smallest possible near vision optotype. In the present study, we used a 20/20 near vision optotype for the measurement of apparent accommodation. SUBJECTS AND METHODS Forty-six eyes of thirty-eight patients (45-84 years old) who had undergone cataract surgery and intraocular lens implantation, and had at least 20/20 best corrected visual acuity at near and far distances, were used in this study. After the eyes were corrected by glasses to gain the best corrected long distance visual acuity, they were forced to watch a 20/20 near vision optotype. Then we gradually added plus lenses until they could recognize the optotype. The value of apparent accommodation was recorded by subtracting the value of plus lens by which the eye could first recognize the 20/20 near vision optotype from three diopters. RESULTS The value of apparent accommodation was 0.00-3.00 D (medium 0.50 D). Two eyes had three diopters of apparent accommodation. CONCLUSION In the present study with correction of astigmatism and small near vision optotype, most eyes showed smaller apparent accommodation than those in previous studies. Despite that, patients with three diopters of apparent accommodation do exist. To analyze high quality visual functions, we should use the smallest possible near vision optotype for the measurement of apparent accommodation.

Abstract
Nine hundred and ninety-three patients who underwent surgical removal of the mandibular third molars with oral antibiotic prophylaxis were examined to determine the incidence of postoperative deep fascial space infection and its background factors. Postoperative deep fascial space infection was observed in 8 of the patients (0.8%; 4 males and 4 females), and submandibular spaces were involved in all infected patients. Only 1 of these 8 patients was an immune compromised host. Patients aged 30 years or more had a significantly higher incidence of deep fascial space infection than those aged under 30. Five patients had partial bony impactions and 3 had complete bony impactions. However, the incidence of infection according to the molar positions was not significantly different between partial bony impaction and complete bony impaction. The 8 patients had not had pericoronitis preoperatively. The clinical courses of all were favorable after antibiotics were administered intravenously. In conclusion, the incidence of deep fascial space infection after removal of the mandibular third molars was low, at 0.8%. However, it may be desirable to remove the molars, if applicable, at a younger age because of the higher incidence of infection in patients aged over 30. The results of this study also offer information that will be useful as a basis for obtaining informed consent from patients whose mandibular third molars are to be removed.

Abstract
Myasthenia gravis (MG) is characterized by weakness of skeletal muscles because of a decrease in the number of available acetylcholine receptors at neuromuscular junctions. Anticholinesterase medication is widely used to treat MG, but muscarinic side effects sometimes appear and limit the drug usage. To their knowledge, the authors present the first case of coronary spastic angina quite possibly induced by anticholinesterase medication to treat MG. The appearance of coronary spastic angina in the present case is likely mediated through the increase of acethylcholine by anticholinesterase medication.

Abstract
Galectin-3 is a member of the beta-galactoside-binding mammalian lectin family with affinity to ABH group epitopes, cell surface and extracellular polylactosamine glycans. It has been shown to be involved in differentiation, morphogenesis, tumor progression, and metastasis. Here we questioned the possible involvement of galectin-3 in the neoplastic progression of the tongue epithelium and evaluated its prognostic value in tongue cancer patients. Galectin-3 expression was analyzed by the immunohistochemical method in 77 tongue specimens (54 squamous cell carcinomas and 23 specimens of distinct normal mucosa). Levels of nuclear expression of galectin-3 markedly decreased during the progression from normal to cancerous states (P < 0.0001), while cytoplasmic expression increased (P < 0.0001). Enhanced expression of galectin-3 in the cytoplasm was associated with a reduced disease-free survival of tongue cancer patients. Multivariate analysis identified enhanced expression of cytoplasmic galectin-3 as an independent predictor of disease recurrence (P = 0.0120). These results suggest that the observed translocation of galectin-3 from the nucleus to the cytoplasm during neoplastic progression may serve as a prognostic factor for tongue cancer patients.
