Abstract
The foraging strategy of many animals is thought to be determined by their past experiences. However, few empirical studies have investigated whether this is true in diving animals. We recorded three-dimensional movements and mouth-opening events from three Antarctic fur seals during their foraging trips to examine how they adapt their behaviour based on past experience--continuing to search for prey in the same area or moving to search in a different place. Each dive cycle was divided into a transit phase and a feeding phase. The linear horizontal distance travelled after feeding phases in each dive was affected by the mouth-opening rate during the previous 244 s, which typically covered two to three dive cycles. The linear distance travelled tended to be shorter when the mouth-opening rate in the previous 244 s was higher, i.e. seals tended to stay in the same areas with high prey-encounter rates. These results indicate that Antarctic fur seals follow decision-making strategies based on the past foraging experience over time periods longer than the immediately preceding dive.

Abstract
The ϕ-Λ(1520) interference effect in the γp→K^{+}K^{-}p reaction has been measured for the first time in the energy range from 1.673 to 2.173 GeV. The relative phases between ϕ and Λ(1520) production amplitudes were obtained in the kinematic region where the two resonances overlap. The measurement results support strong constructive interference when K^{+}K^{-} pairs are observed at forward angles but destructive interference for proton emission at forward angles. Furthermore, the observed interference effect does not account for the sqrt[s]=2.1 GeV bump structure in forward differential cross sections for ϕ photoproduction. This fact suggests possible exotic structures such as a hidden-strangeness pentaquark state, a new Pomeron exchange, or rescattering processes via other hyperon states.

Abstract
OBJECTIVES Although tight control of rheumatoid arthritis (RA) has been achieved through the development of effective medication, surgical intervention is still required for a certain subpopulation of patients. To examine the systemic effects of orthopaedic surgery, we evaluated improvements in disease activity, daily function, and medication after surgery. METHOD A prospective cohort study was conducted in 196 cases of elective orthopaedic surgery in 150 patients with RA from January 2011 to March 2014 in our institution. The 28-joint count Disease Activity Score based on erythrocyte sedimentation rate (DAS28-ESR) and modified Health Assessment Questionnaire (mHAQ) scores just before surgery and at 6 and 12 months after surgery were examined prospectively. Concomitant medications were also investigated. RESULTS Significant improvement was seen in the DAS28-ESR and mHAQ scores for replacement surgery in both the upper and lower extremities, and for arthroplasty/arthrodesis in the upper extremities at the 12-month follow-up. Partial mHAQ scores for the lower extremities were significantly reduced in lower replacement surgery, and partial mHAQ scores for the upper extremities were significantly reduced in upper arthroplasty/arthrodesis surgery. Although the use of conventional synthetic disease-modifying anti-rheumatic drugs (csDMARDs) did not decrease after surgery, the dose of prednisolone (PSL) decreased significantly at 12 months after surgery, especially in the well-controlled group and in surgical procedures in the lower extremities. CONCLUSIONS Elective orthopaedic surgery improves both systemic disease activity and general functional impairment. Orthopaedic surgery is effective in reducing the amount of medication required postoperatively.

Abstract
UNLABELLED The relationship between periarticular osteoporosis in the distal forearm and joint destruction or functional impairment in patients with rheumatoid arthritis (RA) is not sufficiently elucidated. From a single institutional cohort study, we found a strong correlation between periarticular forearm bone mineral density (BMD) and joint destruction or functional impairment. INTRODUCTION This study was conducted to investigate (1) the difference between various periarticular regions of interest (ROIs) of BMD of the forearm, (2) the correlation between periarticular forearm BMD and joint destruction and physical function, (3) the independent variables for predicting BMD of the forearm, and (4) the forearm BMD of different ROIs in the early stage of RA. METHODS We conducted a cross-sectional study in an RA cohort. Measurements included BMD of the distal forearm, joint destruction of the hands assessed by modified total Sharp score (mTSS), functional impairment assessed by a health assessment questionnaire (HAQ), and other clinical data. Variables affecting the forearm BMD values were analyzed by correlation and stepwise regression analyses. RESULTS Of the 405 patients enrolled in the present study, 370 (average age; 62.9 years) were identified as having definite RA with a complete set of data. BMD in the distal end of the forearm (BMDud) was significantly reduced compared with that in the distal third of the forearm (BMD1/3). In a stepwise regression analysis, the mTSS in BMD1/3 was an independent predicting variable, while age and partial HAQ scores associated with the upper extremity were common independent variables in BMDud and BMD1/3. BMDud was significantly less than BMD1/3, even in patients with a short duration of the disease. BMD1/3 was significantly less in non-remission group compared with that in remission group in patients with a short duration of the disease. CONCLUSION Periarticular BMD in the distal forearm is closely correlated with joint destruction and functional impairment in RA. Periarticular BMD in the distal forearm may be already reduced at the clinical manifestation of the disease.

Abstract
The COMPASS Collaboration at CERN has measured diffractive dissociation of 190 GeV/c pions into the π(-)π(-)π(+) final state using a stationary hydrogen target. A partial-wave analysis (PWA) was performed in bins of 3π mass and four-momentum transfer using the isobar model and the so far largest PWA model consisting of 88 waves. A narrow peak is observed in the f0(980)π channel with spin, parity and C-parity quantum numbers J(PC)=1(++). We present a resonance-model study of a subset of the spin-density matrix selecting 3π states with J(PC)=2(++) and 4(++) decaying into ρ(770)π and with J(PC)=1(++) decaying into f0(980)π. We identify a new a1 meson with mass (1414(-13)(+15)) MeV/c2 and width (153(-23)(+8)) MeV/c2. Within the final states investigated in our analysis, we observe the new a1(1420) decaying only into f0(980)π, suggesting its exotic nature.

Abstract
We have constructed an improved version of a photon-counting phase-modulation fluorometer (PC-PMF) with a maximum modulation frequency of 1.0 GHz, where a phase domain measurement is conducted with a time-correlated single-photon-counting electronics. While the basic concept of the PC-PMF has been reported previously by one of the authors, little attention has been paid to its significance, other than its weak fluorescence measurement capability. Recently, we have recognized the importance of the PC-PMF and its potential for fluorescence lifetime measurements. One important aspect of the PC-PMF is that it enables us to perform high-speed measurements that exceed the frequency bandwidths of the photomultiplier tubes that are commonly used as fluorescence detectors. We describe the advantages of the PC-PMF and demonstrate its usefulness based on fundamental performance tests. In our new version of the PC-PMF, we have used a laser diode (LD) as an excitation light source rather than the light-emitting diode that was used in the primary version. We have also designed a simple and stable LD driver to modulate the device. Additionally, we have obtained a sinusoidal histogram waveform that has multiple cycles within a time span to be measured, which is indispensable for precise phase measurements. With focus on the fluorescence intensity and the resolution time, we have compared the performance of the PC-PMF with that of a conventional PMF using the analogue light detection method.

Abstract
The COMPASS collaboration at CERN has investigated pion Compton scattering, π(-)γ→π(-)γ, at center-of-mass energy below 3.5 pion masses. The process is embedded in the reaction π(-)Ni→π(-)γNi, which is initiated by 190 GeV pions impinging on a nickel target. The exchange of quasireal photons is selected by isolating the sharp Coulomb peak observed at smallest momentum transfers, Q(2)<0.0015 (GeV/c)(2). From a sample of 63,000 events, the pion electric polarizability is determined to be α(π)=(2.0±0.6(stat)±0.7(syst))×10(-4) fm(3) under the assumption α(π)=-β(π), which relates the electric and magnetic dipole polarizabilities. It is the most precise measurement of this fundamental low-energy parameter of strong interaction that has been addressed since long by various methods with conflicting outcomes. While this result is in tension with previous dedicated measurements, it is found in agreement with the expectation from chiral perturbation theory. An additional measurement replacing pions by muons, for which the cross-section behavior is unambiguously known, was performed for an independent estimate of the systematic uncertainty.

Abstract
OBJECTIVE The objective was to assess involvement of loss of the PRKAR1A gene encoding a type 1α regulatory subunit of cAMP-dependent protein kinase A located on 17q24 in a Carney complex (CNC)-related pituitary adenoma. DESIGN We investigated aberrations of the PRKAR1A gene in a CNC patient with a GH-producing pituitary adenoma, whose family has three other members with probable CNC. METHODS A gene mutation was identified by a standard DNA sequencing method based on PCR. DNA copy number was measured to evaluate allelic loss on 17q24 by quantitative PCR. The breakpoints of deletion were determined by cloning a rearranged region in the deleted allele. RESULTS A PRKAR1A mutation of c.751_758del8 (p.S251LfsX16) was found in genomic DNA obtained from a pituitary adenoma, but not leukocytes from the patient. Reduced DNA copy number at loci including the PRKAR1A gene on 17q24 was detected in both the tumor and leukocytes, suggesting a deletion at the loci at the germline level. The deletion size was determined to be ∼ 0.5 Mb and this large deletion was also found in two other family members. CONCLUSION This is the first case showing a CNC-related pituitary adenoma with the combination of somatic mutation and a large inherited deletion of the PRKAR1A gene. Biallelic inactivation of PRKAR1A appears to be necessary for the development of CNC-related pituitary adenoma.

Abstract
BACKGROUND AND OBJECTIVE Migration of the junctional epithelium occurs in association with the formation of a periodontal pocket. Although the migration of junctional epithelium is known to be related to the proliferation and migration of gingival junctional epithelial cells, the mechanism has not been clarified. In patients with periodontitis, the levels of interleukin-8 (IL-8) in both gingival tissue and gingival crevicular fluid are dramatically increased. IL-8 has broad bioactive functions. In this study, we examined the role of IL-8 in DNA synthesis, migration and protection against apoptosis in cultured human gingival epithelial cells (HGEC). MATERIAL AND METHODS DNA synthesis was estimated by measuring the incorporation of bromodeoxyuridine. The migration of gingival epithelial cells was assessed in a wound-healing assay. The expression of integrin beta-1 was analyzed using immunofluorescence confocal microscopy and western blotting. Cleaved caspase-3 was detected using western blotting and a Caspase-Glo assay kit. RESULTS IL-8 increased the synthesis of DNA in HGEC, and the maximal effect was seen at 25 or 50 ng/mL of IL-8. In addition, 50 ng/mL of IL-8 induced cell migration, and a neutralizing antibody of integrin beta-1 inhibited the migration. IL-8 also activated expression of integrin beta-1. Furthermore, IL-8 reduced the Aggregatibacter actinomycetemcomitans-induced increase in caspase-3 expression in HGEC. CONCLUSION IL-8 may facilitate the migration of gingival junctional epithelium by enhancing DNA synthesis, migration and preventing apoptosis of gingival epithelial cells.

Abstract
BACKGROUND In steroid-naive patients with asthma, several gene variants are associated with a short-term response to inhaled corticosteroid (ICS) treatment; this has mostly been observed in Caucasians. However, not many studies have been conducted for other ethnicities. Here, we aimed to determine the relationship between the annual decline in forced expiratory flow volume in one second (FEV1 ) and the variant of the glucocorticoid-induced transcript 1 gene (GLCCI1) in Japanese patients with asthma receiving long-term ICS treatment, taking into account the effect of high serum periostin levels, a known association factor of pulmonary function decline and a marker of refractory eosinophilic/Th2 inflammation. METHODS In this study, 224 patients with asthma receiving ICS treatment for at least 4 years were enrolled. The effects of single-nucleotide polymorphisms (SNPs) in GLCCI1, stress-induced phosphoprotein 1 (STIP1), and T gene on the decline in FEV1 of 30 ml/year or greater were determined. RESULTS Besides the known contributing factors, that is, the most intensive treatment step, ex-smoking, and high serum periostin levels (≥95 ng/ml), the GG genotype of GLCCI1 rs37973, and not other SNPs, was independently associated with a decline in FEV1 of 30 ml/year or greater. When patients were stratified according to their serum periostin levels, the GG genotype of rs37973 was significantly associated with blood eosinophilia (≥250/μl) in the high serum periostin group. CONCLUSIONS A GLCCI1 variant is a risk factor of pulmonary function decline in Japanese patients with asthma receiving long-term ICS treatment. Thus, GLCCI1 may be associated with response to ICS across ethnicities.

Abstract
BACKGROUND Epidemiological studies have shown that smoking increases the propensity for atopy and asthma. However, the effects of smoking on atopy and eosinophilic inflammation in asthmatics, including the elderly, remain unknown. OBJECTIVE To determine the effects of smoking on serum immunoglobulin E (IgE) levels and eosinophilic inflammation in asthmatics of all ages. METHODS The associations of serum IgE levels, blood eosinophil counts and fractional exhaled nitric oxide (FeNO) levels with smoking and age in steroid-naive asthmatics were cross-sectionally assessed (n = 307). Levels of sputum eosinophil and thymic stromal lymphopoietin (TSLP) that promotes Th2 inflammation were also analysed. Current smokers were excluded when analysing contributing factors of FeNO. RESULTS Levels of serum IgE, blood eosinophil and FeNO decreased with increasing age in never-smokers, whereas decrease in serum IgE levels with increasing age was not observed in current smokers. In addition, current smoking was associated with higher blood eosinophil counts. In atopic asthmatics, age-related declines in serum IgE levels were less steep in ex-smokers than in never-smokers, and atopic ex-smokers with asthma showed higher blood eosinophil counts and higher FeNO irrespective of age. Lastly, sputum TSLP levels were associated with sputum eosinophil proportions and pack-years. Current and ex-smokers had higher TSLP levels than never-smokers. CONCLUSIONS AND CLINICAL RELEVANCE In steroid-naive asthmatics, smoking may attenuate the age-related decrease in IgE levels and maintain eosinophilic inflammation, in which TSLP may be involved.

Abstract
Abstract
Background: Coping with cancer plays an important role in cancer survivorship. Especially in young patients, coping is significant because of anxieties regarding fertility, body image, heredity, symptoms of premature menopause, and psychosocial stress. According to previous studies, the group intervention therapy is effective in improving emotional difficulties for breast cancer patients. However, there is few demonstrating the efficacy of group intervention for young breast cancer patients.
Methods: Since September 2010, we have conducted a clinical trial of a group intervention, facilitated by breast surgeons, psycho-oncologists, and nurses, for young breast cancer patients who were diagnosed under 35, or 36 years old due to enrolling period, and they had no metastasis. at St Luke's International Hospital (SLIH) in Tokyo, Japan. Each group consisted of 7 to 10 breast cancer patients, who received five weekly sessions. We evaluated the changes in coping strategies, emotional levels, and quality of life (QOL) before, after and 6 month after the group intervention, by using three scales: MAC (Mental Attitude to Cancer) for coping, POMS (Profile of Mood States) for emotional states, and FACT-B (Functional Assessment of Cancer Therapy-Breast) for QOL. MAC scale includes five coping strategies such as Fighting Spirit(FS), Hopelessness(H), Anxious Preoccupation(AP), Anxiety(A), and Fatalism(F). This is an interim report of this clinical trial. Paired T-test was used to statistical evaluation.
Results: At this point, 65 young patients finished the group intervention. Complete data were taken from 61 patients for evaluating score changes between before and after the group interventions. POMS and FACT-B score improved statistically (p = 0.004, p = 0.003). Among MAC's five components, Hopelessness and Anxious Preoccupation improved statistically (p<0.01, p<0.001).
Discussion: This study suggests that the group intervention is promising to improve emotion states, QOL, and coping strategies for young breast cancer patients.

Abstract
Abstract
Background: Due to advancement of cancer treatment, the number of cancer survivors is increasing and our society also needs to consider cancer survivorship. Especially the prevalence of breast cancer by age is much younger in Japan than in western countries. About half of them were diagnosed in 30-50’s, and they are considered strong working force in society.
Cancer and its treatment largely affect their working status, therefore support system for workers with cancer is urgently required.
Methods: We established support systems by 3 phases. We assessed the effect of breast cancer and informational needs in Japanese young breast cancer survivors for working with cancer (Phase 1). We also estimated economic impact due to such work force loss from cancer (Phase 2). Furthermore, we designed intervention model “Working Ring” by health care providers for cancer survivors to facilitate returning to work or keeping their job, and evaluated its effect (Phase3).
Results: Among 42 young (less than 35 years old) breast cancer survivors who worked at the time of diagnosis, 33% of them had to changed their role at work after diagnosis of breast cancer. Focused interview revealed they needed informational and emotional support system. According to the Japanese Health Ministry of Health, Labor and Welfare database, we estimated total economic loss due to cancer treatment, $1569 million for women and $2959 million for men. Breast cancer is estimated as a number one cause of economic loss among cancer survivors in Japan. Finally, we introduced group intervention for working survivors provided by health care professionals (psycho-oncologist, nurse, and medical social worker) and labor and social security attorney. In this “Working Ring”, patients were given information about working status, practical issues provided by their companies and our society in order to maintain their work. We enrolled total 22 working breast cancer survivors divided in 3 groups; each group was given by 3 sessions of one-hour group intervention. All attendees of the group intervention showed increase in knowledge and problem solving technique concerning working, and QOL improvement by using POMS.
Discussion: We noted that there are many unmet needs for working breast cancer survivors and loss of their job causes enormous impact for social economy. Surprisingly, breast cancer is estimated number one cause of economic loss from cancer diagnosis in Japan. It is urgently required to establish support systems for working cancer survivors. Our group interventional model “Working Ring” was very successful to improve their anxiety and informational needs. We are currently extending this model through entire Japan.
Conclusions: Most of cancer survivors are considered to be potential working force. To establish a support system for them to maintain working ability and environment is necessary for societal reintegration.

Abstract
Metastatic pulmonary calcification, defined as calcium deposition in the intact lung, is commonly seen in patients with chronic renal failure, and it is known to be a benign clinical condition when detected by chance in an asymptomatic patient. Here we report the case of a 33-year-old woman who developed rapid and aggressive metastatic pulmonary calcification shortly after a living donor kidney transplantation, which induced acute antibody-mediated rejection. The patient's metastatic pulmonary calcification was successfully improved by extensive treatment for graft rejection, the correction of her accompanying primary hyperparathyroidism, and medical treatment with a bisphosphonate and sodium thiosulfate. Aggressive pulmonary calcification is reported as a rare complication seen in patients who have undergone a failed renal transplantation. A failed renal graft and accompanying secondary hyperparathyroidism seem to accelerate metastatic calcification. Most of the patients who develop aggressive pulmonary calcification suffer from the rapid progression of dyspnea and occasionally fever, and they die of respiratory failure. Pulmonary calcification should be considered in a patient developing dyspnea and unexplained pulmonary infiltrate, especially in the context of renal graft rejection; otherwise the prognosis of the patient will be very poor.

Abstract
This study was conducted to investigate the distribution and diversity of extended-spectrum cephalosporin (ESC) resistance determinants in Salmonella enterica and Escherichia coli obtained from the same cecal samples and to provide evidence of transmission of the resistance determinants among these bacteria in broiler farms in southern Japan. Salmonella enterica and E. coli were characterized by serotyping and multilocus sequence typing, respectively. An antimicrobial susceptibility test, plasmid analysis, and identification and localization of resistance genes were performed to determine the relatedness of ESC resistance determinants among the isolates. Of 48 flocks examined, 14 had S. enterica. In total, 57 S. enterica isolates were obtained, 45 of which showed ESC resistance. Extended-spectrum cephalosporin-resistant E. coli were also obtained from all of these ESC-resistant Salmonella-positive samples. β-Lactamase genes, blaTEM-52 (38 isolates), blaCTX-M-14 (1 isolate), and blaCMY-2 (6 isolates), were carried by conjugative untypable or IncP plasmids detected in the S. enterica serovars Infantis and Manhattan. The β-lactamase genes blaCTX-M-14 (3 isolates), blaCTX-M-15 (3 isolates), blaSHV-2 (1 isolate), blaSHV-12 (2 isolates), and blaCMY-2 (32 isolates) associated with IncI1-Iγ, IncFIB, IncFIC, IncK, IncB/O, and IncY plasmids were detected in E. coli co-isolates. Restriction mapping revealed similar plasmids in Salmonella Infantis and Salmonella Manhattan and in different sequence types of E. coli. Intraspecies transmission of plasmids was suggested within S. enterica and E. coli populations, whereas interspecies transmission was not observed. This study highlights the importance of plasmids as carriers of ESC resistance determinants.

Abstract
Campylobacter jejuni was monitored in 4 chicken farms during the period 2003 to 2006 to elucidate the mechanisms of transmission. Three farms (1 to 3), located at least 14 km from each other, belonged to an integrated poultry company, which also provided the farms with day-old chicks from several hatcheries as well as chicken feed. Another farm (4), which belonged to a different company, was located 270 m from farm 1. A total of 206 C. jejuni isolates obtained from the 4 farms were classified into 10 flaA-based RFLP types. Identical RFLP types were found in isolates obtained from chickens originating from multiple hatcheries and reared in different chicken houses on individual farms. Flocks were colonized by strains with 1 or 2 RFLP types in each production cycle, sometimes differing between cycles. Identical RFLP types were found in isolates obtained from the environment around the chicken houses. Using multilocus sequence typing, strains with different RFLP types could be distinguished from each other. Identical RFLP and multilocus sequence typing profiles were found in isolates obtained from farms 1 and 4, and from farms 1 and 2. These results suggest that C. jejuni in these farms comes from common sources external to the farms, even if the farms belong to different companies and obtain chicks from different suppliers.

Abstract
Rodent incisors exhibit pigmentation on their labial surfaces. Although previous studies have shown that this pigment is composed of iron, the existence of other elements has not been investigated. This study found that the lower incisors of CD61, also known as integrin β3, null mice (CD61(-/-)) lacked pigmentation. Although ameloblasts differentiated and formed enamel normally, no ferric ion accumulation was observed in maturation-stage ameloblasts in CD61(-/-) mice. Surface elements of control and CD61-/- lower incisors were compared by x-ray photoelectron spectroscopy (XPS). XPS analysis detected C, Ca, N, O, and P on the labial surfaces of lower incisors of both mice, whereas Fe was detected only in control samples. No peak of non-ferrous metal or other element was detected in either group. Quantitative RT-PCR analysis of 18 iron-transportation-related genes with mRNA from maturation-stage ameloblasts and ALC, a pre-ameloblastic cell line, was performed. The results suggested that CD61 regulates the expressions of Slc11a2 and Slc40a1, both of which are involved in iron transportation in epithelial tissues. These results suggested that the pigment on the labial surface of mouse incisors is composed of Fe and that both anemia and reduction of iron-transporting proteins may cause the loss of pigmentation in CD61(-/-) mice.

Abstract
A delay in establishing the diagnosis of an occult fracture of the hip that remains unrecognised after plain radiography can result in more complex treatment such as an arthroplasty being required. This might be avoided by earlier diagnosis using MRI. The aim of this study was to investigate the best MR imaging sequence for diagnosing such fractures. From a consecutive cohort of 771 patients admitted between 2003 and 2011 with a clinically suspected fracture of the hip, we retrospectively reviewed the MRI scans of the 35 patients who had no evidence of a fracture on their plain radiographs. In eight of these patients MR scanning excluded a fracture but the remaining 27 patients had an abnormal scan: one with a fracture of the pubic ramus, and in the other 26 a T1-weighted coronal MRI showed a hip fracture with 100% sensitivity. T2-weighted imaging was undertaken in 25 patients, in whom the diagnosis could not be established with this scanning sequence alone, giving a sensitivity of 84.0% for T2-weighted imaging. If there is a clinical suspicion of a hip fracture with normal radiographs, T1-weighted coronal MRI is the best sequence of images for identifying a fracture.

Abstract
The COMPASS Collaboration at CERN has investigated the π- γ → π- π- π+ reaction at center-of-momentum energy below five pion masses, sqrt[s]<5m(π), embedded in the Primakoff reaction of 190 GeV pions impinging on a lead target. Exchange of quasireal photons is selected by isolating the sharp Coulomb peak observed at smallest momentum transfers, t'<0.001 GeV2/c2. Using partial-wave analysis techniques, the scattering intensity of Coulomb production described in terms of chiral dynamics and its dependence on the 3π-invariant mass m(3π)=sqrt[s] were extracted. The absolute cross section was determined in seven bins of sqrt[s] with an overall precision of 20%. At leading order, the result is found to be in good agreement with the prediction of chiral perturbation theory over the whole energy range investigated.

Abstract
Here, we present the first case of post-thymectomy Myasthenia Gravis with onset at Osserman stage III. An 81-year-old woman was admitted for an abnormal shadow seen in a chest radiograph. She had no symptoms of Myasthenia Gravis. Acetylcholine receptor antibody was within the normal range. Chest computed tomography (CT) showed a bulky anterior mediastinal tumor. She was diagnosed as having thymoma by tissue biopsy under CT guidance. The tumor was completely resected by performing thymothymectomy, left upper lobectomy, pericardial resection, and phrenicectomy. Pathological examination of the tumor identified it as a thymoma (type B2, Masaoka stage II). Two months after the surgery, she experienced the onset of post-thymectomy myasthenia gravis with Osserman stage III. The acetylcholine receptor antibody level was remarkably elevated (220 nmol/L); however, there was no evidence of tumor recurrence.

Abstract
396 Background: Cetuximab is now considered a standard treatment for advanced or unresectable colorectal cancer, unfortunately patients suffer a skin reaction as the main indication of the toxicity of cetuximab. It is recently reported that Kampo medicine (Goshajinkigan) is considered to be an effective agent for the neuropathy of oxaliplatin. Kampo medicine “Juzen-taiho-to” (TJ-48, Tsumura CO. Ltd.), which consists of 10 component herbs, is known as a tonic agent which improves the general systemic condition of cancer patients by reducing the adverse effects of chemotherapy, radiation therapy, and surgical treatment and to inhibit metastases. The aim of this study was to clarify the efficacy of TJ-48 for adverse events associated with cetuximab therapy. Methods: From 2009, cetuximab was administered initially at a dose of 400 mg/m2 followed by weekly infusions at 250 mg/m2 to 20 patients with non-resectable or recurrent colorectal cancer. Eighteen patients received oral administration of 7.5 g/day of TJ-48 (TJ-48 group) every day in the first course and 7 patients did not receive TJ-48 (Control group). Adverse events were evaluated for every course according to CTCAE version 3.0. Results: There was no statistically significant difference between the two groups based on any of patient characteristics. No patients complained of persistent Grade 3 infusion reaction. The percentage of Grade 2 or more skin reactions in each course tended to be lower in the TJ-48 group compared with the Control group (TJ-48 group 34% vs control group 57%). Incidence of Grade 2 anorexia in the TJ-48 group was significantly lower than in the Control group (TJ-48 group 34% vs control group 71%, p=0.03). There were no differences regarding tumor response between the two groups. Conclusions: TJ-48 is useful to prevent anorexia in non-resectable or recurrent colorectal cancer patients treated with cetuximab regimen. [Table: see text]

Abstract
570 Background: Combination protocol using FU-LV with irinotecan (FOLFIRI) is currently regarded as standard first-line therapy in advanced colorectal cancer (CRC). Although irinotecan prolongs survival, it causes severe diarrhea and neutropenia. Recent pharmacogenetic studies on irinotecan have revealed significant associations of UDP-glucuronosyltransferase 1A1 (UGT1A1) polymorphisms *28 and *6, the latter being specifically detected in East Asians resulting in severe toxicity. It is necessary that the dose-finding trial that decided the optimal dose according to the gene polymorphism to draw out the maximum therapeutic effect while evading the side effect. Here we present the result of prospective trial of the safety about FOLFIRI therapy according to each gene type of UGT1A1 for Japanese patients with advanced CRC. Methods: From 2008, 250 Japanese patients in TOKUSHIMA University were enrolled in this study. Homo group (*6/*6 and *28/*28 or a both hetero types), hetero group (It was *28 and either *6 was hetero type), and wild group (*28 and *6 were wild types) were defined. On the 23 patients with advanced CRC treated with FOLFIRI after standard chemotherapy, wild and homo groups were administered 150mg/m2 irinotecan, and homo group was 100mg/m2. Results: On the 23 patients, the genotypes of UGT1A1 *28 were homozygous in 1 (0.5%) and heterozygous in 5 (28%), *6 were homozygous in 0 and heterozygous in 6 (26%). In *6 heterozygous patients, severe toxicities (grade 3 or more) were found (33%), but in *28 heterozygous patients were not (0%). There was no decrease of irinotecan doses in each group. In Japanese people, UGT1A1 *6 polymorphisms were higher than *28 (*6 homo 3%, hetero 27% vs *28 homo 0.5%, hetero 13%). Conclusions: When the dosage of irinotecan is decided, it is necessary to consider the UGT1A1 *6 heterozygous in Japanese cancer patients. [Table: see text]
