Abstract
BACKGROUND Human epidermal growth factor receptor 3 (HER3) is broadly expressed in non-small-cell lung cancer (NSCLC) and is the target of patritumab deruxtecan (HER3-DXd), an antibody-drug conjugate consisting of a HER3 antibody attached to a topoisomerase I inhibitor payload via a tetrapeptide-based cleavable linker. U31402-A-U102 is an ongoing phase I study of HER3-DXd in patients with advanced NSCLC. Patients with epidermal growth factor receptor (EGFR)-mutated NSCLC that progressed after EGFR tyrosine kinase inhibitor (TKI) and platinum-based chemotherapy (PBC) who received HER3-DXd 5.6 mg/kg intravenously once every 3 weeks had a confirmed objective response rate (cORR) of 39%. We present median overall survival (OS) with extended follow-up in a larger population of patients with EGFR-mutated NSCLC and an exploratory analysis in those with acquired genomic alterations potentially associated with resistance to HER3-DXd. PATIENTS AND METHODS Safety was assessed in patients with EGFR-mutated NSCLC previously treated with EGFR TKI who received HER3-DXd 5.6 mg/kg; efficacy was assessed in those who also had prior PBC. RESULTS In the safety population (N = 102), median treatment duration was 5.5 (range 0.7-27.5) months. Grade ≥3 adverse events occurred in 76.5% of patients; the overall safety profile was consistent with previous reports. In 78/102 patients who had prior third-generation EGFR TKI and PBC, cORR by blinded independent central review (as per RECIST v1.1) was 41.0% [95% confidence interval (CI) 30.0% to 52.7%], median progression-free survival was 6.4 (95% CI 4.4-10.8) months, and median OS was 16.2 (95% CI 11.2-21.9) months. Patients had diverse mechanisms of EGFR TKI resistance at baseline. At tumor progression, acquired mutations in ERBB3 and TOP1 that might confer resistance to HER3-DXd were identified. CONCLUSIONS In patients with EGFR-mutated NSCLC after EGFR TKI and PBC, HER3-DXd treatment was associated with a clinically meaningful OS. The tumor biomarker characterization comprised the first description of potential mechanisms of resistance to HER3-DXd therapy.

Abstract
The purpose of this study was to evaluate in detail both the in vivo and in vitro efficacy of the enzyme agents, ZYMOX® Plus Otic (ZYMOX-P), in the treatment of canine otitis externa (OE). Eight dogs with a diagnosis of non-seasonal severe chronic OE were recruited for the study. ZYMOX-P was administered for 2-4 weeks. The Otitis Index Score (OTIS3) and bacteria or yeast colony growth were measured. Also, minimum biofilm (BF) formation inhibition concentration (MBIC) and BF bactericidal concentration (BBC) were measured in vitro. OTIS3 showed a statistically significant reduction after treatment (88.2%, p⟨0.001; pre-treatment = 11.0 ± 0.9; post-treatment = 1.3 ± 0.4, mean ± SEM). The individual OTIS scores, erythema, edema, erosions/ ulcerations, exudate and pruritus showed significant reduction (85.7%, 95.7%, 83.3%, 80.0%, and 89.3%, respectively). Microscopic examination revealed the presence of BF exopolysaccharide in all 8 ear samples when stained with alcian blue. Seven of the 8 dogs (87.5%) showed a reduction in colony growth. ZYMOX-P was effective at 34-fold and 16-fold dilutions on MBIC and BBC, respectively. These findings indicate that ZYMOX-P has efficacy against BF-related infection and is beneficial when used for the management of canine OE.

Abstract
BACKGROUND Genetic markers of susceptibility to asthma exacerbations in adults remain unclear. OBJECTIVE To identify genetic markers of asthma exacerbations, particularly in patients with type-2 inflammatory endotype. METHODS In this observational study of patients enrolled in the Kinki Hokuriku Airway disease Conference multicenter study, frequency of exacerbations requiring systemic corticosteroids during 2 years after enrolment and associated risk factors was determined. For genetic marker analysis, interleukin-4 receptor α (IL4RA) rs8832 and a disintegrin and metalloprotease 33 (ADAM33) S_2 (rs528557), T_1 (rs2280091), T_2 (rs2280090), and V_4 (rs2787094) variants were included. Elevated serum periostin levels at enrolment (≥95 ng/mL, defined as type-2 inflammatory endotype) were considered in the analysis. RESULTS Among 217 patients who were successfully followed up for 2 years after enrolment, 60 patients showed at least one asthma exacerbation during the 2 years. Airflow limitation (%FEV1 <80%) and recent exacerbations but not genetic variants were identified as risk markers of exacerbations. A total of 27 patients showed type-2 inflammatory endotype (serum periostin ≥95 ng/mL at enrolment) and subsequent exacerbations; risk factors in these patients were airflow limitation (odds ratio, 6.51; 95% confidence interval (CI): 2.37-18.6; P=.0003), GG genotype of IL4RA rs8832 (odds ratio, 4.01; 95% CI: 1.47-11.0; P=.007), and A allele of ADAM33 T_2 (odds ratio, 2.81; 95% CI: 1.05-7.67; P=.04) by multivariate analysis. In addition, GG genotype of IL4RA rs8832 was associated with type-2 endotype, whereas A allele of ADAM33 T_2 was associated with mixed type of eosinophilic/type-2 and neutrophilic inflammations. CONCLUSIONS AND CLINICAL RELEVANCE IL4RA and ADAM33 variants may be risk markers of asthma exacerbations in type-2 inflammatory endotype. Precise endotyping may facilitate the identification of genetic risk markers of asthma exacerbations.

Abstract
In this study, dogs were separated into two groups and treated with immunosuppressant (Cyclosporin A: CsA). The first group was the canine atopic dermatitis (CAD) group, which is similar to extrinsic atopic dermatitis (AD) in humans (treated with a CsA dose of 2.5-5.5 mg/kg, n=8), and the second group was the canine atopic-like dermatitis (ALD) group, which is similar to intrinsic AD in humans (treated with a CsA dose of 2.5-6.5 mg/kg, n=14). The canine atopic dermatitis extent and severity index (CADESI)-4 was evaluated before treatment (PRE) and after treatment (POST) to assess the effectiveness of CsA for the two groups. In the CAD group, CADESI-4 showed no change (PRE:79±29, POST:77±28) and out of the eight dogs, no dogs showed complete remission, three dogs showed partial remission, and five dogs showed no effect. Whereas in the ALD group, CADESI-4 showed a significant reduction (PRE: 61±42, POST: 32±25, p<0.01) and out of the 14 dogs, 11 dogs showed complete remission, two dogs showed partial remission, and one dog showed no effect. The results indicate that the immunosuppressant showed effectiveness for the dogs diagnosed with ALD. One dog had to be treated for a year and eight months, which was the longest period in the study, this dog presented with hyperplasia of the lymphoidgland and mammary tumor.

Abstract
BACKGROUND AND PURPOSE The incidence of wall enhancement of cerebral aneurysms on vessel wall MR imaging has been described as higher in ruptured intracranial aneurysms than in unruptured intracranial aneurysms, but the difference in the degree of enhancement between ruptured and unruptured aneurysms is unknown. We compared the degree of enhancement between ruptured and unruptured intracranial aneurysms by using quantitative MR imaging measures. MATERIALS AND METHODS We performed quantitative analyses of circumferential enhancement along the wall of cerebral aneurysms in 28 ruptured and 76 unruptured consecutive cases by using vessel wall MR imaging. A 3D-T1-weighted fast spin-echo sequence was obtained before and after contrast media injection, and the wall enhancement index was calculated. We then compared characteristics between ruptured and unruptured aneurysms. RESULTS The wall enhancement index was significantly higher in ruptured than in unruptured aneurysms (1.70 ± 1.06 versus 0.89 ± 0.88, respectively; P = .0001). The receiver operating characteristic curve analysis found that the most reliable cutoff value of the wall enhancement index to differentiate ruptured from unruptured aneurysms was 0.53 (sensitivity, 0.96; specificity, 0.47). The wall enhancement index remained significant in the multivariate logistic regression analysis (P < .0001). CONCLUSIONS Greater circumferential enhancement along the wall of cerebral aneurysms correlates with the ruptured state. A quantitative evaluation of circumferential enhancement by using vessel wall MR imaging could be useful in differentiating ruptured from unruptured intracranial aneurysms.

Abstract
Abstract
Twenty dogs with canine atopic dermatitis (CAD) were treated with rush sublingual immunotherapy (SLIT), with a 48 hour build-up phase and 6 months maintenance phase (treated by antigen once every 3-4 weeks). The canine atopic dermatitis extent and severity index (CADESI)-4 was evaluated before treatment (baseline) and after 6 months. An open, non-controlled, non-randomized pilot trial was conducted to assess the effectiveness and safety of rush SLIT for environmental allergen extracts (Dematophagoides pteronyssinus and D.farinae mix and other). Three dogs dropped out and 17 dogs finished the trial. CADESI-4 at baseline was 60.6±27.1 (range 17-107, n=17). After 6 months of SLIT treatment, CADESI-4 was 37.4±36.0 (range 5-152, n=17) (p <0.01), which was a 38.3% reduction. A significant improvement, defined as a CADESI-4 reduction of > 30%, was observed in 13 out of 17 dogs (76%). A moderate improvement, defined as a CADESI-4 reduction of ≦30%, was observed in 2 dogs (12%). In the other 2 dogs (12%), CADESI-4 worsened or showed no change. However, no severe adverse effects were observed during the trial.
Therefore, rush SLIT against environmental allergen extract for CAD showed effectiveness and safety as evidenced by the reduction of CADESI-4 after 6 months SLIT without severe adverse effects.

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.

3-Hydroxymethyl-5-aziridinyl-1-methyl-[1H-indole-4,7-dione]-prop-beta-en -alpha-ol (EO9) is a bioreductive anticancer agent active for non-small cell lung cancer (NSCLC) and structurally related to mitomycin C (MMC). DT-diaphorase (DTD) is regarded as a two electron reductase that plays an important role in the biotransformation of MMC to antitumor metabolites. To evaluate the role of DTD as a bioactivator of EO9 in NSCLC cell lines under oxic and hypoxic conditions, we examined the inhibitory effect of dicumarol which was regarded as a selective inhibitor of DTD on the sensitivity to EO9 in vitro. In this study, we used an MMC-resistant NSCLC cell line (PC-9/MC4) which was established from a PC-9 cell line as a parent cell line by continuous exposure to MMC in our laboratory. We reported previously that the subline PC-9/MC4 was 6.7-fold more resistant to MMC than PC-9 with decreased DTD activity. The IC50 value of PC-9 against EO9 was significantly increased by co-incubation with dicumarol under oxic conditions. EO9 was more cytotoxic against PC-9/MC4 than against PC-9 cells and the enhancement was impaired by tempol under hypoxic conditions. These findings suggest a suppressive role of DTD against one-electron reduction pathway in the bioactivation of EO9 under hypoxic conditions and EO9 may be more active against oxygen-deficient solid tumors especially in MMC-resistant NSCLC cells with low levels of DTD activity.

Abstract
DT-diaphorase (DT-D) is regarded as a two-electron reductase that plays an important role in the biotransformation of mitomycin C (MMC) to antitumor metabolites, which is enhanced under hypoxic conditions. To evaluate the role of DT-D as a bioactivator of MMC and its analogue, KW-2149, in non-small cell lung cancer (NSCLC) cell lines under an aerobic or hypoxic condition, we examined the inhibitory effect of dicumarol which was regarded as an inhibitor of DT-D on the sensitivity to these anticancer agents in vitro. In this study, we used an MMC-resistant NSCLC cell line (PC-9/MC4) which was established in our laboratory from a PC-9 cell line as a parent cell line by continuous exposure to MMC. The subline PC-9/MC4 was 6.7-fold more resistant to MMC than PC-9, the parent cell line, under aerobic conditions, and 5.2-fold more resistant even under hypoxic conditions. PC-9/MC4 cell lines did not show collateral resistance to KW-2149, a newly developed MMC analogue. The IC50 value of PC-9 against MMC significantly decreased by co-incubation with dicumarol under aerobic, but not under hypoxic conditions. KW-2149 was cytotoxic to PC-9/MC4 as well as PC-9 cells, and the sensitivity to KW-2149 was not altered by coincubation with dicumarol or exposure to hypoxia. There were no significant differences in intracellular uptake of MMC and the activities of cytosolic detoxification enzymes, GST and GSH, between PC-9 and PC-9/MC4 cell lines under aerobic conditions. These findings suggest a partial role of DT-D in bioactivation of MMC, but not of KW-2149, under aerobic conditions. However, the detailed mechanisms of drug resistance to MMC under hypoxic conditions are still not clear.

Abstract
Cisplatin is a key drug in chemotherapy for lung cancer. It has been reported that intracellular accumulation of cisplatin is an important step as a determinant for resistance to cisplatin, which may be modulated by Na+, K+-ATPase activity. And it has been reported that beta-adrenoceptor agonists modulate the Na+, K+-ATPase in some organs. In this study, the effects of a beta-adrenoceptor agonist and an antagonist on membrane Na+, K+-ATPase activity were evaluated using human non-small cell (NSCLC) lung cancer cell lines. In the NSCLC cell lines, sensitivity to cisplatin was improved by treatment with isoproterenol. Na+, K+-ATPase was activated and intracellular accumulation of cisplatin increased with the treatment. But the antagonist, propranolol, did not modulate sensitivity to cisplatin or Na+, K+-ATPase activity. These results suggest that beta-adrenoceptors may be one of the determinant for sensitivity to cisplatin in NSCLC, but endogenous catecholamine dose not play a role in the intracellular accumulation of cisplatin in these cell lines. Exogenous beta-adrenoceptor agonists may improve the antitumor effect of chemotherapy involving cisplatin.

Abstract
BACKGROUND AND PURPOSE At diagnosis, the primary clinical manifestations of pediatric Moyamoya disease are TIA or CSs. CSs are reported to be more prevalent in younger than in older children. We sought to determine whether age-related differences in clinical manifestations are associated with age-related angiographic differences. MATERIALS AND METHODS We divided 78 patients diagnosed with Moyamoya disease before 16 years of age into four 4-year age groups and examined the relationships between age at diagnosis and clinical manifestations and angiographic and MR imaging findings. RESULTS Among the 4 diagnostic age groups, in those younger than 4 years of age, the prevalence of CSs and of infarctions on MR images was highest, and along with severity of steno-occlusive lesions of the PCA, the prevalence was significantly higher than that in the next diagnostic age group (4-7 years), though the severity of steno-occlusive lesions in the ICA and the degree of transdural collaterals did not differ significantly. The prevalence of CSs and infarctions did not differ significantly in the 3 oldest diagnostic age groups, whereas ICA and PCA lesions and transdural collaterals correlated positively with diagnostic age. CONCLUSIONS The high prevalence of CSs and infarctions in patients diagnosed before 4 years of age is associated with advanced steno-occlusive lesions of the PCA. In patients 4 years of age and older at diagnosis, transdural collaterals develop in parallel with advancement of ICA and PCA lesions, which may contribute to the nearly constant prevalence of CSs.

Abstract
8096 Background: Epidermal growth factor receptor (EGFR) mutations, amplification, and K-ras mutations are known as predictive factor of the EGFR tyrosine kinase inhibitor (EGFR-TKI) therapy in patients (pts) with NSCLC. Prognostic influences of those biomarkers remain the matter to be discussed. Methods: Consecutive pts with advanced NSCLC who were examined EGFR genotype and received 1st line cytotoxic chemotherapy were enrolled. EGFR amplification and K-ras mutation were analyzed if sufficient tumor samples were available. Results: 87 pts were enrolled in this study. EGFR mutations or K-ras mutations were found in 26 of 87 (29.9%) or 2 of 65 (3.1%) pts, respectively. As to objective response rate (ORR), no significant differences were observed among pts with EGFR mutations, K-ras mutations, and pts without both mutations. Progression free survival (PFS) in 1st line cytotoxic chemotherapy was 8.4, 1.0, and 3.9 months in pts with EGFR mutations, with K-ras mutations, and pts without both mutations, respectively. PFS was longer in pts with EGFR mutations compared with the pts without both mutations (p=0.0234). We also found the pts with K-ras mutations had shorter PFS compared with pts without both mutations (p=0.0203). Overall survival (OS) was 29.7, 2.3 and 13.4 months in pts with EGFR mutations, with K-ras mutations, and pts without both mutations, respectively. Significant differences were found between pts with EGFR mutation and without both mutations (p=0.0001) and between pts without both mutations and with K-ras mutations (p=0.0001). Pts with EGFR amplification were found in 21 of 78 (26.9%). There were no differences between EGFR amplification positive and negative in terms of ORR, PFS and OS. 87 of 68 (78.2%) pts received EGFR-TKI therapy in the second line or later. As previously reported, both EGFR mutations and amplifications were good predictive marker of ORR, PFS and OS in pts treated with EGFR-TKI. Conclusions: EGFR mutations were good predictive marker and K-ras mutations were poor predictive marker in first line cytotoxic chemotherapy. There is the possibility that EGFR and K-ras mutations have the prognostic impact in advanced NSCLC. [Table: see text]

Abstract
e19040 Background: Gemcitabine (GEM) and vinorelbine (VNR) combination have demonstrated activity as a 1st-line treatment in elderly patients with advanced non-small-cell lung cancer (NSCLC). Gefitinib (GEF) is effective as a 2nd-line treatment for NSCLC. We conducted a multicenter phase II trial to evaluate the efficacy and toxicity for treatment of GEM+VNR followed by sequential GEF in elderly patients (pts) with advanced or metastatic NSCLC. Primary endpoint is response rate, secondary endpoints were safety, progression-free survival (PFS), and overall survival (OS). Methods: Eligibility required hitologically or cytologically comfirmed NSCLC, no prior therapy, measurable lesion(s), ECOG PS 0–2, age equal to or over 70 years, and adequate organ functions. Patients were received 3 cycles, each at 4-week intervals, of GEM (1000 mg/m2, d 1, 15) and VNR (25mg/m2 d 1, 15), followed by 250 mg of GEF daily until disease progression or unacceptable toxicity. Results: Between June 2004 and November 2007, 60 pts were enrolled and 2 pts withdrew consent. Fifty-eight pts (35 male and 23 female, median age 77 years) were evaluated. Median number of GEM+VNR administrations was 3 (range 1–3). Median duration of GEF was 101 days (range 9–652 days). Grade 3/4 toxicities included leucopenia (29%), neutoropenia (40%), anemia (12%), febrile neutropenia (9%), and anorexia (9%) during GEM+VNR, anorexia (2%), and constipation (2%) during GEF. Best response rate of GEM+VNR was 17% and that after sequential GEF was 31%. Median PFS and median OS were 4.2 months and 12.6 months, respectively. Response rate, PFS, and OS were significantly favorable in female and never-smoker. Conclusions: Sequential treatment consisted with GEM+VNR and GEF was feasible with acceptable toxicities in elderly patients with NSCLC. [Table: see text]

Abstract
BACKGROUND AND PURPOSE Moyamoya disease is an idiopathic occlusive cerebrovascular disorder with abnormal microvascular proliferation. We investigated the clinical utility of leptomeningeal high signal intensity (ivy sign) sometimes seen on fluid-attenuated inversion recovery images in Moyamoya disease. MATERIALS AND METHODS We examined the relationship between the degree of the ivy sign and the severity of the ischemic symptoms in 96 hemispheres of 48 patients with Moyamoya disease. We classified each cerebral hemisphere into 4 regions from anterior to posterior. In 192 regions of 24 patients, we examined the relationship between the degree of the ivy sign and findings of single-photon emission CT, including the resting cerebral blood flow (CBF) and cerebral vascular reserve (CVR). RESULTS The degree of the ivy sign showed a significant positive relationship with the severity of the ischemic symptoms (P < .001). Of the 4 regions, the ivy sign was most frequently and prominently seen in the anterior part of the middle cerebral artery region. The degree of the ivy sign showed a negative relationship with the resting CBF (P < .0034) and a more prominent negative relationship with the CVR (P < .001). CONCLUSIONS The leptomeningeal ivy sign indicates decreased CVR in Moyamoya disease.

Abstract
BACKGROUND AND OBJECTIVE Cyclooxygenase (COX) is an enzyme that converts arachidonic acid to prostanoids. There are two isoforms of COX, namely COX-1 and COX-2. COX-2 is highly inducible by several stimuli and is associated with inflammation. Recent studies have shown that COX-2 is upregulated in the airway epithelium of patients with asthma but little is known about the role it plays in cough, a common symptom of bronchial asthma. This study was designed to investigate the role of COX-2 in cough reflex sensitivity in patients with asthma. PATIENTS AND METHODS The effect of etodolac, a potent COX-2 inhibitor, on cough response to inhaled capsaicin was examined in 17 patients with stable asthma in a randomized, placebo-controlled crossover study. Capsaicin cough threshold, defined as the lowest concentration of capsaicin eliciting 5 or more coughs, was measured as an index of airway cough reflex sensitivity. RESULTS The geometric mean (geometric SEM) cough threshold was significantly increased after a 2-week treatment program with oral etodolac (200 mg twice a day) compared with placebo (36.7 [1.2] vs 21.6 [1.2] gM, P<.02). CONCLUSIONS These findings indicate that COX-2 may be a possible modulator augmenting airway cough reflex sensitivity in asthmatic airways.

Abstract
The aim of this study was to evaluate the usefulness of EGFR mutation status in serum DNA as a means of predicting a benefit from gefitinib (IRESSA) therapy in Japanese patients with non-small cell lung cancer (NSCLC). We obtained pairs of tumour and serum samples from 42 patients treated with gefitinib. EGFR mutation status was determined by a direct sequencing method and by Scorpion Amplification Refractory Mutation System (ARMS) technology. EGFR mutations were detected in the tumour samples of eight patients and in the serum samples of seven patients. EGFR mutation status in the tumours and serum samples was consistent in 39 (92.9%) of the 42 pairs. EGFR mutations were strong correlations between both EGFR mutation status in the tumour samples and serum samples and objective response to gefitinib (P<0.001). Median progression-free survival time was significantly longer in the patients with EGFR mutations than in the patients without EGFR mutations (194 vs 55 days, P=0.016, in tumour samples; 174 vs 58 days, P=0.044, in serum samples). The results suggest that it is feasible to use serum DNA to detect EGFR mutation, and that it's potential as a predictor of response to, and survival on gefitinib is worthy of further evaluation.

Abstract
7599 Background: In the phase III Iressa (gefitinib) Survival Evaluation in Lung cancer (ISEL) trial, high epidermal growth factor receptor (EGFR) gene copy number was a predictor of a gefitinib effect on survival in patients (pts) with refractory advanced non-small-cell lung cancer (NSCLC) (hazard ratio 0.61 vs 1.16 for high vs low copy number; p=0.045) [JCO 2006;24:5034–42]. Although EGFR mutation status may predict response to gefitinib in Japanese pts, there is insufficient data to clarify if high EGFR gene copy number assessed by fluorescence in situ hybridization (FISH) is predictive in these pts. This analysis investigated the applicability of both published Colorado FISH criteria (Colorado Univ) and new FISH criteria to Japanese NSCLC pts. Methods: 58 tumor specimens from gefitinib-treated Japanese pts were analyzed using Vysis LSI EGFR and CEP7 (chromosome 7 control) FISH probes. Specimens were classed as FISH+ or - using Colorado and exploratory (EGFR/cell; CEP7/cell; EGFR/CEP7; % of cells with various numbers of EGFR or CEP7 signals) criteria. Results: Of the 58 pts, 17 (29%) had an objective response (OR). Using Colorado criteria, OR was 50% in the 14 FISH+ pts vs 23% in the 44 FISH- pts (2-sided Fisher's exact test p=0.089). There was a trend for an association between FISH+ status and improved survival (log rank p=0.15). Defining FISH+ as specimens with =5% cells containing >5 EGFR signals, OR was significantly better among FISH+ pts vs FISH- pts (p=0.0030; 52% of the 23 FISH+ pts responding vs 14% of the 35 FISH- pts). A survival advantage was not indicated. Defining FISH+ as =74% of cells with EGFR or CEP7 loss (<2 signals) or gain (>2 signals), OR was significantly better among FISH+ pts vs FISH- pts (p=0.043; 45% of the 22 FISH+ pts responding vs 19% of the 36 FISH- pts). Association with survival had marginal significance (log rank p=0.061). Conclusions: These preliminary data have identified loss or gain of EGFR and CEP7 abnormality as promising biomarkers for response to gefitinib in Japanese NSCLC patients. Analysis of these markers for correlation with time to progression is ongoing. Investigation of these potential markers in other cohorts of patients is worthy of further evaluation. [Table: see text]

Abstract
BACKGROUND Adhesion molecules such as intercellular adhesion molecule-1 (ICAM-1) are thought to contribute to the airway inflammation and airway hyper-responsiveness (AHR) of allergic asthma. Some differences from allergic asthma have been noted, including airway neutrophilia, and the involvement of ICAM-1 in toluene diisocyanate (TDI) asthma is currently unclear. OBJECTIVE We utilized mice lacking ICAM-1 expression (ICAM-1(-/-)) to investigate the role of ICAM-1 in airway inflammation and AHR in TDI-induced asthma. METHODS Male C57BL/6J mice (ICAM-1(+/+)) and ICAM-1(-/-) mice were intranasally sensitized to TDI solution or solvent alone. Airway inflammation, AHR and cytokine secretion were assessed 24 h after challenge by TDI or solvent. The production of antigen-specific IgG and IgE by TDI sensitized and non-sensitized mice was determined. RESULTS TDI challenge to ICAM-1(+/+) mice induced an increase in airway inflammatory cell numbers, AHR and cytokine secretion of TNF-alpha, macrophage inflammatory protein-2 (MIP-2), IL-4, IL-5 and IFN-gamma into the bronchoalveolar lavage fluid. All these pathophysiological changes were reduced in ICAM-1(-/-) mice. Serum levels of TDI-specific IgG and IgE of ICAM-1(-/-) and ICAM-1(+/+) mice were comparable. CONCLUSION These results suggest that ICAM-1 plays an essential role in airway inflammation and AHR in TDI-induced asthma.

Abstract
OBJECT Hemorrhage from cerebral vascular malformations such as cerebral cavernous malformation (CCM) can result in significant mortality and morbidity, but its underlying mechanism is undetermined. Excessive degradation of the vascular matrix by matrix metalloproteinases (MMPs), proteolytic enzymes that degrade all the components of extracellular matrix, can lead to instability of the vascular structure and can thereby cause bleeding. Thus we examined the expression of MMPs and tissue inhibitors of metalloproteinase (TIMP) in CCM. PATIENTS AND METHODS We performed immunohistochemistry for MMP-2, -9, and TIMP-2 using Paraffin-embedded sections of the surgical specimens obtained from seven patients with CCM. All patients had a history of hemorrhage from CCM. FINDINGS In all patients (7/7, 100%), MMP-2 and -9 were strongly expressed in endothelial cells of CCMs. Endothelial expression of TIMP-2 was also evident in all seven patients. In contrast, MMP-2, -9 and TIMP-2 were not identified in adjacent normal brain tissue. CONCLUSION We found that CCM showed the increased endothelial expression of MMP-2, -9, and TIMP-2. Endothelial expression of MMPs and/or TIMP may affect the vascular matrix stability, and thus can contribute to hemorrhage from CCM.

Abstract
Pathogenesis-related (PR) proteins are often used as a marker of plant defense reactions. Some endo-1,3-beta-glucanase (Gns) genes encode proteins that belong to the PR protein family 2 (PR-2). Although the number of homologous family member genes is significantly greater in hexaploid wheat (Triticum aestivum L.) compared to other model plants, earlier studies did not evaluate the possible contribution of their homologs to hybridization signals in Northern blot analysis. In this study, we have examined whether routine transcriptional analyses of a PR gene is of high reliability or not by isolating six highly similar Gns genes (TaGlb2a, TaGlb2b, TaGlb2c, TaGlb2d, TaGlb2e, and TaGlb2f) and characterizing their expression patterns in detail. While TaGlb2b was shown to be a PR-2 gene, transcription of TaGlb2c and TaGlb2d was not induced upon infection with either powdery mildew (Erysiphe graminis) or head blight (Fusarium graminearum) pathogens; their transcripts were most abundant in healthy spikes (lemmas and in particular paleae). Therefore, in some cases, the conventional analyses do not necessarily provide accurate information on expression pattern of a PR gene in hexaploid wheat. This is also the first report of wheat genes that are specifically expressed in lemma/palea tissues of flowering spikelets.

Abstract
Although acute upper respiratory diseases (AURDs) such as common cold and influenza are common, few interventions have been proven to be effective in their prevention and treatment. The aim of this study was to assess the efficacy of ambroxol for preventing AURD. Fifty-four patients were randomly divided into 3 groups: a rebamipide (non-mucoactive drug) group (300 mg/day), carbocisteine group (1500 mg/day) and ambroxol group (45 mg/day). The study was divided into 2 terms, the first half-year (summer season) and the second half-year (winter season). In the preceding winter, only 19.5% of the patients had been vaccinated against influenza viruses (flu). The primary goal of this study was to evaluate the effectiveness of mucoactive drugs in decreasing the frequency of AURD. Treatment with ambroxol, but not carbocisteine, significantly reduced the median number of AURD episodes (P=0.0049 vs. rebamipide). Thirty-three patients without vaccination against flu were assessed especially during the second half-year. Treatment with ambroxol also significantly reduced the median number of AURD episodes in this assessment (P=0.0028 vs. rebamipide in the second half-year). In conclusion, ambroxol may be useful for preventing AURD.

Abstract
Cystinuria is caused by the inherited defect of apical membrane transport systems for cystine and dibasic amino acids in renal proximal tubules. Mutations in either SLC7A9 or SLC3A1 gene result in cystinuria. The mutations of SLC7A9 gene have been identified mainly from Italian, Libyan Jewish, North American, and Spanish patients. In the present study, we have analyzed cystinuria cases from oriental population (mostly Japanese). Mutation analyses of SLC7A9 and SLC3A1 genes were performed on 41 cystinuria patients. The uptake of 14C-labeled cystine in COS-7 cells was measured to determine the functional properties of mutants. The protein expression and localization were examined by Western blot and confocal laser-scanning microscopy. Among 41 patients analyzed, 35 were found to possess mutations in SLC7A9. The most frequent one was a novel missense mutation P482L that affects a residue near the C-terminus end of the protein and causes severe loss of function. In MDCK II and HEK293 cells, we found that P482L protein was expressed and sorted to the plasma membrane as well as wild type. The alteration of Pro482 with amino acids with bulky side chains reduced the transport function of b(0,+)AT/BAT1. Interestingly, the mutations of SLC7A9 for Japanese cystinuria patients are different from those reported for European and American population. The results of the present study contribute toward understanding the distribution and frequency of cystinuria-related mutations of SLC7A9.

Abstract
13030 Background: In non-small cell lung cancer (NSCLC), sensitivity to gefitinib is associated with activating mutations of the epidermal growth factor receptor (EGFR). Tumor samples obtained for diagnosis of NSCLC are limited and often unsuitable for analysis of mutations. Other biomarkers are thus needed. We previously reported that serum vascular endothelial growth factor (VEGF) levels were significantly lower in responders to gefitinib than non-responders. To assess levels of circulating VEGF as a predictive and prognostic marker of gefitinib treatment in NSCLC patients, we examined the associations between plasma VEGF levels before gefitinib treatment and clinical outcome. Methods: Eighty four NSCLC patients treated with gefitinib were enrolled into this investigation. Plasma VEGF levels were measured in blood samples before gefitinib administration. Patients were grouped according to VEGF level around a cut-off of 80.7 pg/ml, based on results from normal controls. Response to gefitinib was judged using RECIST guidelines. Time to progression (TTP) and overall survival (OS) following gefitinib treatment were calculated using Kaplan-Meier methods. Groups were compared using log-rank test. We evaluated the immunohistochemical expression of VEGF and EGFR mutations in tumor samples from 37 patients. Results: Response rate was significantly higher with low VEGF level than with high VEGF level (p = 0.0010). Multivariate analysis for response to gefitinib including sex, histology, smoking status, performance status and plasma VEGF level identified only low VEGF level as predictive of response to gefitinib. Low VEGF level was also correlated with prolonged median TTP (4.1 months vs. 1.1 months, p = 0.0081) and OS (11.1 months vs. 5.4 months, p = 0.0290). Multivariate analysis for survival revealed low VEGF level as associated with prolonged TTP (p = 0.0081) and OS (p = 0.0708). Plasma VEGF level was not associated with either VEGF expression or EGFR mutations of tumor tissue. Conclusions: Our results suggest that plasma VEGF levels before gefitinib treatment are predictive of response to gefitinib and prognostic of patients who receive gefitinib. [Table: see text]

Abstract
7192 Background: Epidermal growth factor receptor (EGFR) gene amplification and mutation have been reported to be predictors of response to EGFR inhibitors. We evaluated EGFR gene copy number and mutations in biopsy samples of non-small cell lung cancer (NSCLC) treated with gefitinib (G) and analyzed the correlation between gene status and clinical outcome. Methods: EGFR gene copy numbers in biopsy samples were evaluated using FISH and categorized as described by Cappuzzo et al. We also performed mutational analysesof exons 18, 19 and 21 of EGFR by PCR and direct sequencing. Response was judged using the RECIST guidelines. Time to progression (TTP) and overall survival (OS) were calculated and evaluated by the Kaplan-Meier method. Groups were compared using the log-rank test. Risk factors associated with survival were evaluated using Cox proportional hazards regression modeling and multivariable analysis. Results: Of 59 patients (pts) enrolled in this investigation, 24 pts (41%) were female and 21 pts (35%) had never smoked. The most common histological subtype was adenocarcinoma (73%) and 36 pts (61%) had good PS 0–1. Gene copy numbers could be analyzed in 54 pts. Gene amplification was observed in 21 pts, high polysomy in 5 pts, low polysomy in 18 pts, low trisomy in 5 pts and disomy in 5 pts. FISH positivity was observed in 26 pts (48%). EGFR mutations were detected in 18 pts (31%); point mutations in exon 21 were observed in 5 pts, in-frame deletions in exon 19 in 12 pts, a point mutation in exon 18 in 1 pt. Response rate in pts with EGFR mutations was significantly higher than in pts without mutations (56% vs. 15%, p = .0011). Response rate in FISH-positive pts was 31% and that in FISH-negative pts was 21%, the association with response was not significant. EGFR mutations were also correlated with improved TTP (median 8.3 m vs. 1.8 m, p = .0014) and OS (median 18.8 m vs. 6.4 m, p = .0059). There were no significant differences in TTP and OS based on FISH positivity. On multivariable analysis, EGFR mutations remained significantly associated with improved TTP and OS. Conclusions: Our results suggest that EGFR mutations are a better predictor of clinical benfit of G when compared with gene copy number in Japanese NSCLC pts. [Table: see text]

Abstract
BACKGROUND Gastrooesophageal reflux (GER) is a frequent cause of chronic cough. Several investigators have indicated that inhibitors of H(+)K(+)ATPase (proton pump inhibitors; PPIs) could relieve coughing via inhibition of acid reflux. However, we considered that PPIs might directly inhibit increased cough reflex sensitivity. OBJECTIVE The present study was designed to examine whether PPIs directly inhibit antigen-induced increase in cough reflex sensitivity and to elucidate the mechanism. METHODS Actively sensitized guinea-pigs were challenged with aerosol antigen (ovalbumin, OVA) and cough reflex sensitivity to inhaled capsaicin was measured 24 h later. The PPIs (omeprazole and rabeprazole) or the histamine H(2) blocker cimetidine were administered intraperitoneally 1 h before OVA challenge and before measuring cough reflex sensitivity, then bronchoalveolar lavage fluid (BALF) was immediately collected. The pH of the fluid obtained by bronchial washing was determined after examining the effect of rabeprazole on the cough response to capsaicin. RESULTS The number of coughs elicited by capsaicin was significantly increased 24 h after challenge with OVA compared with saline, indicating antigen-induced increase in cough reflex sensitivity. Both PPIs dose dependently and significantly inhibited antigen-induced cough hypersensitivity. Omeprazole did not influence the antigen-induced increase in the total number of cells or ratio (%) of eosinophils in BALF. Cimetidine did not affect the antigen-induced cough hypersensitivity or cellular components of BALF. The pH of the bronchial washing fluid was significantly decreased in antigen-challenged animals. Rabeprazole did not affect the antigen-induced decrease in the pH of bronchial washing fluid. CONCLUSION These findings show that PPIs, but not histamine H(2) blockers, can directly decrease antigen-induced cough reflex hypersensitivity, while the mechanism remains unclear.

Abstract
Patients receiving paclitaxel or docetaxel also receive a significant amount of ethanol, as both products contain ethanol as solvent. Patients in our clinics have occasionally exhibited signs of alcohol intoxication immediately after paclitaxel infusion. In 2002, the Japanese government lowered the minimum ethanol concentration for the definition of drunk driving, with the threshold breath alcohol concentration (BRAC) of 0.15 mg/l. The aim of this study was to measure BRAC in Japanese outpatients treated with paclitaxel or docetaxel and to assess intoxication according to this standard. Fifty-two Japanese patients were enrolled from October 2003 to February 2004. Patient characteristics were as follows: male/female, 13/39: median age, 71 (range: 34-78); breast/lung/ovarian cancer 24/16/12; and paclitaxel/docetaxel treatment: 36/16, respectively. The mean total doses of paclitaxel or docetaxel were 178 mg (range: 107-300) and 53 mg (30-100), respectively. Breath samples were measured three times immediately following the infusion of paclitaxel or docetaxel via ethyl alcohol detector and the mean value was recorded. BRAC was detected in 20 patients (56%) with paclitaxel and in none of the docetaxel patients. BRAC was measured again 30 min after the initial measurement in BRAC-detected cases with the patients' permission. In four of six BRAC-remeasured patients, BRAC became undetectable after 30 min. There was no correlation between the total doses of paclitaxel and BRAC or between the infusion rates of paclitaxel and BRAC. In conclusion, clinicians should recognize the potential for alcohol intoxication with paclitaxel administration. Patients should be instructed to avoid driving on the day of paclitaxel administration.

Abstract
BACKGROUND Airway inflammation and remodelling are characteristic features of chronic asthma. OBJECTIVE To elucidate the role of interleukin (IL)-6 in airway responses to chronic antigen exposure. METHODS We compared airway inflammation, subepithelial collagen deposition, cytokine mRNA expression, and airway responsiveness between IL-6-deficient and wild-type (WT) mice following sensitization and repeated exposure to ovalbumin (OVA) three times a week for 8 weeks. RESULTS The repeated exposure to OVA induced infiltration of eosinophils, neutrophils, and lymphocytes into the airway, and caused thickening of the basement membrane and subepithelial fibrosis. IL-6-deficient mice exhibited more pronounced infiltration of these cells, a thinner basement membrane, and decreased subepithelial fibrosis, compared with WT mice. The repeated OVA exposure increased expression of IL-4, IL-13, eotaxin, monocyte chemoattractant protein-1 (MCP-1), and transforming growth factor-beta1 mRNA in WT mice. Among these factors, expression of IL-13 and MCP-1 mRNA was further enhanced in IL-6-deficient mice, compared with WT mice. However, both WT and IL-6-deficient mice exhibited similar levels of airway responsiveness to increasing doses of methacholine, even after repeated exposure to OVA. CONCLUSION These results suggest that IL-6 has dual roles in the chronic phase of asthma: down-regulation of inflammatory cell infiltration and enhancement of airway remodelling.

Abstract
OBJECTIVE Three-dimensional anisotropy contrast (3-DAC) magnetic resonance imaging and magnetoencephalography (MEG) of visually evoked magnetic fields (VEFs) were used to accurately localize the optic radiation and primary visual cortex before surgery for an occipital tumor. PATIENT AND METHODS A 26-year-old male presented with an occipital lobe tumor located intrinsically underneath the right calcarine fissure. 3-DAC imaging showed that the right optic radiation was located along the superior and lateral surfaces of the lesion. Mapping of the VEFs demonstrated that the primary visual cortex was located superior and lateral to the lesion. The lesion was totally resected via an infero-medial cortical incision using a frameless stereotactic system. Histopathology indicated a pilocytic astrocytoma. No visual deficit was found before or after surgery. CONCLUSION Combined 3-DAC imaging and MEG can provide essential information about the optic radiation and primary visual cortex for planning the surgical treatment of occipital lobe tumors.

Abstract
BACKGROUND There is controversy about extensive surgical treatment for a malignant astrocytic tumour in more elderly patients who may have poorer outcomes and higher complication rates. This retrospective study investigated outcome in elderly patients with malignant astrocytic tumour before and after the adoption of routine clinical use of magnetic resonance (MR) imaging. METHODS During 1982 through 1999, 88 patients with malignant astrocytic tumour aged 60 years or over were treated in our institute. Thirty-seven patients had an anaplastic astrocytoma and 51 had a glioblastoma. Thirty-seven patients treated from 1982 to 1988 did not have pre-operative evaluation by MR imaging (Group A), 26 patients treated from 1989 to 1995 had preoperative MR imaging evaluation (Group B), and 25 patients treated after 1996 underwent preoperative MR imaging with functional brain mapping and intra-operative navigation system monitoring (Group C). FINDINGS The median survival time was 8.8 months in Group A, 12.7 months in Group B, and 17.6 months in Group C. Patients with glioblastoma in Group B (11.7 months, n = 15) and Group C (16.0 months, n = 19) had significantly longer median survival time than in Group A (6 months, n = 17) (P = 0.0054 between Groups A and B, P = 0.0024 between Groups A and C). Better preoperative performance status, more thorough surgical resection, and better performance status after the initial treatment was obtained after the introduction of MR imaging, and patients with the optimal indicators showed significantly longer survival time compared with the patients without these factors. INTERPRETATION Pre-operative MR imaging may contribute to longer survival time by providing an earlier diagnosis in patients with better performance status, by allowing more thorough surgical resection, and resulting in better performance status after the treatment.

Abstract
BACKGROUND Indoor formaldehyde (FA) might worsen allergies and be an underlying factor for the increasing incidence and severity of asthma; the exact mechanism, however, remains unclear. OBJECTIVE The present study examined the effects of repeated exposure to FA on methacholine- and antigen-induced bronchoconstriction in guinea-pigs in vivo. METHODS First, non-sensitized guinea-pigs were transnasally treated with 0.1 or 1.0% FA or saline three times a week for 6 weeks, and increasing concentrations of methacholine (50, 100, and 200 microg/mL) were inhaled at 5-min intervals. Second, guinea-pigs pre-treated with transnasal administration of FA or saline using the same protocol were passively sensitized with anti-ovalbumin (OA) serum 7 days before antigen challenge. Third, guinea-pigs were actively sensitized with OA and pre-treated with transnasal administration of FA or saline using the same protocol. The lateral pressure of the tracheal tube (Pao) was measured under anesthesia and artificial ventilation. RESULTS The antigen-induced increase in Pao in actively sensitized guinea-pigs was significantly potentiated by FA exposure in a dose-dependent manner. The dose-response curve of the methacholine-induced increase in Pao in non-sensitized guinea-pigs or of the antigen-induced increase in Pao in passively sensitized guinea-pigs was not altered by FA exposure. Transnasal administration of FA significantly increased the serum anti-OA homocytotropic antibody titre (IgG) as measured by the passive cutaneous anaphylaxis reaction in actively sensitized guinea-pigs. CONCLUSION The results suggest that repeated exposure to FA worsens allergic bronchoconstriction through enhancing antigen sensitization.
