Abstract
Background: Not following the infant formula package instruction endangers infant health. Although infant formula misuse has been reported abroad, its incidence in Japan remains unknown. Furthermore, it is reasonable to assume that experience in childcare reduces the likelihood of making mistakes in using infant formula. This study aimed to examine the association between compliance with infant formula package instruction and childcare experience in Tokyo and surrounding prefectures in Japan. Methods: Using a web-based questionnaire, mothers with infants were analyzed cross-sectionally and surveyed regarding their infants’ nutrition and formula preparation methods in August 2021. Compliance with the infant formula package was determined according to (a) using unlabeled infant formula, (b) preparing infant formula without reading package instructions, (c) giving formula to children ≥ 2 h after preparing, and (d) adding other ingredients to the formula bottle. The association between the misuse of infant formula and childcare experience was examined by grouping the participants by infant age (< 6 months and ≥ 6 months), and by comparing first-born child status with later-born. Of the 333 mothers with infants, 3 were excluded due to out-of-scope responses, and 330 were included in the analysis. Results: The major sources of information on infant feeding methods among the participants were obstetric facilities (92.1%), internet (36.1%), and family (20.9%). The proportions of participants using infant formulas not labeled as “infant formula,” such as follow-up milk, not preparing at prescribed concentrations, feeding infant formulas > 2 h after preparation, and adding additional ingredients to the bottle were 7.9%, 4.1%, 23.1%, and 15.9%, respectively, which suggest the misuse of infant formula. These four answers did not differ significantly between mothers of children aged < 6 months and ≥ 6 months or between those with first-born and later-born children. Conclusion: This study suggested that some Japanese mothers do not follow package instructions of infant formula in Japan. The misuse of infant formula may not be related to the length of time spent in childcare or the presence or absence of childcare experience. Providing appropriate information on the correct use of infant formula to all caregivers, regardless of their parenting experience, is required.

Abstract
Meaningful conservation techniques for the endangered Morus boninensis require seed production and storage, since in situ purebred seed production is infrequent in Ogasawara Islands (World Natural Heritage Site) in Japan. Ex situ living M. boninensis specimens produced seeds by open- and artificial-pollination in a greenhouse. Seed desiccation tolerance and storage characteristics were examined. Open-pollinated seeds were dried at 75, 33 and 8% relative humidity (RH) for 5 days then cryopreserved at -170 °C. Artificially pollinated seeds were dried at 8% RH then stored cryogenically at -170 °C and in freezers at -80 or -20 °C for 6 months. Germination rates were compared among seeds before and after drying and storage. Germination rates of undried seeds were 83% for open-pollinated seeds and 65% for artificially pollinated seeds. M. boninensis seeds exhibited the characteristic high desiccation tolerance of orthodox seeds and maintained a high germination rate after drying to a moisture content of approximately 4%. Cryopreservation of open-pollinated dry seeds with moisture contents of ca. 12, 7 and 4% maintained germination rates, while cryopreservation of undried seeds (moisture content ca. 44%) resulted in no germinability. Cryogenic and freezer storage of artificially pollinated dry seeds for 6 months resulted in maintenance of germination rates comparable to undried seeds before storage. Seed production was enabled by ex situ M. boninensis collection. The present study also developed a method for low temperature seed storage. Ex situ living tree collection represents a feasible seed resource for reintroduction and restoration programmes for M. boninensis.

Abstract
BACKGROUND AND OBJECTIVES The relationship between eating rate (ER) and increased risk of obesity in relation to body mass index (BMI, i.e., total body fat) and waist circumference (WC, i.e., abdominal fat) has not been fully examined. Considering gender differences, we identified unknown confounding factors (CFs) for each risk, and then assessed the two actual obesity risks, adjusting for the CFs. METHODS AND STUDY DESIGN Using a questionnaire, we collected data for ER (slow, normal as "reference," and fast) and related factors and measured BMI and WC for 3,393 men and 2,495 women. Using multiple logistic regression models, odds ratios (ORs) and their 95% confidence intervals (CIs) were estimated adjusting for both conventional and candidate CFs. RESULTS The following factors were identified as appropriate CFs, but were differed between the two obesity types: fast food consumption in both genders, sleep duration and restaurants/food service use in men, and family structure and packed lunch in women. In men, actual risks of BMI obesity and WC obesity were negatively associated with slow ER (ORs and 95% CIs; 0.70 and 0.52-0.96, and 0.69 and 0.50-0.96), but positively associated with fast ER (1.48 and 1.25-1.76, and 1.45 and 1.21-1.74). In women, those risks were positively related to fast ER (1.78 and 1.39-2.26, and 1.34 and 1.11-1.61). CONCLUSIONS For both BMI obesity risk and WC obesity risk, we conclude that slow and fast ER were related to decreased and increased risks when adjusted for appropriate CFs, which differed by gender and the obesity type.

Abstract
Supplemental digital content is available in the text. Purpose Although several genetic factors may play a role in leisure-time exercise behavior, there is currently no evidence of a significant genomewide association, and candidate gene replication studies have produced inconsistent results. Methods We conducted a two-stage genomewide association study and candidate single-nucleotide polymorphisms (SNP) association study on leisure-time exercise behavior using 13,980 discovery samples from the Japan Multi-Institutional Collaborative Cohort (J-MICC) study, and 2036 replication samples from the Hospital-based Epidemiologic Research Program at Aichi Cancer Center-2 study. Leisure-time physical activity was measured using a self-administered questionnaire that inquired about the type, frequency and duration of exercise. Participants with ≥4 MET·h·wk−1 of leisure-time physical activity were defined as exhibiting leisure-time exercise behavior. Association testing using mixed linear regression models was performed on the discovery and replication samples, after which the results were combined in a meta-analysis. In addition, we tested six candidate genetic variants derived from previous genomewide association study. Results We found that one novel SNP (rs10252228) located in the intergenic region between NPSR1 and DPY19L1 was significantly associated with leisure-time exercise behavior in discovery samples. This association was also significant in replication samples (combined P value by meta-analysis = 2.2 × 10−9). Several SNP linked with rs10252228 were significantly associated with gene expression of DPY19L1 and DP19L2P1 in skeletal muscle, heart, whole blood, and the nervous system. Among the candidate SNP, rs12612420 in DNAPTP6 demonstrated nominal significance in discovery samples but not in replication samples. Conclusions We identified a novel genetic variant associated with regular leisure-time exercise behavior. Further functional studies are required to validate the role of these variants in exercise behavior.

Abstract
PURPOSE This study aimed to investigate independent relationships of daily non-exercise life activity and leisure-time exercise volume and intensity with the prevalence of metabolic syndrome and its traits in Japanese adults. METHODS Data of 24,625 eligible subjects (12,709 men, 11,916 women) who participated in the baseline survey of the Japan Multi-Institutional Collaborative Cohort (J-MICC) Study were analyzed. Information about lifestyle characteristics was obtained from a questionnaire. Logistic regression analyses were performed to evaluate the independent associations of daily life activity as well as leisure-time exercise volume and intensity with the prevalence of metabolic syndrome and its traits by sex. RESULTS Male subjects with higher daily life activity as well as with higher leisure-time exercise volume had a lower prevalence of metabolic syndrome, independently with each other. Female subjects with higher daily life activity also had a lower prevalence of metabolic syndrome. Particularly, male and female subjects with the highest daily life activity quartile showed considerably low odds ratios of 0.66 (95% CI, 0.53-0.81) and 0.64 (0.52-0.79), respectively, for low HDL-cholesterol even after the adjustment for BMI compared with the first quartile. Meanwhile, male subjects with the higher leisure-time exercise showed a quite lower prevalence of elevated triglycerides. Higher moderate-intensity exercise was more intensely associated with a lower prevalence of metabolic syndrome and some of its traits in both sexes. CONCLUSIONS Our results suggest that higher daily life activity and higher moderate-intensity exercise may be independently associated with a lower risk of metabolic syndrome in Japanese adults.

Abstract
Gout is a common arthritis caused by elevated serum uric acid (SUA) levels. Here we investigated loci influencing SUA in a genome-wide meta-analysis with 121,745 Japanese subjects. We identified 8948 variants at 36 genomic loci (P<5 × 10-8) including eight novel loci. Of these, missense variants of SESN2 and PNPLA3 were predicted to be damaging to the function of these proteins; another five loci-TMEM18, TM4SF4, MXD3-LMAN2, PSORS1C1-PSORS1C2, and HNF4A-are related to cell metabolism, proliferation, or oxidative stress; and the remaining locus, LINC01578, is unknown. We also identified 132 correlated genes whose expression levels are associated with SUA-increasing alleles. These genes are enriched for the UniProt transport term, suggesting the importance of transport-related genes in SUA regulation. Furthermore, trans-ethnic meta-analysis across our own meta-analysis and the Global Urate Genetics Consortium has revealed 15 more novel loci associated with SUA. Our findings provide insight into the pathogenesis, treatment, and prevention of hyperuricemia/gout.

Abstract
Brief exposure to passive smoking immediately elevates blood pressure. However, little is known about the association between exposure to passive smoking and chronic hypertension. We aimed to examine this association in a cross-sectional study, after controlling multiple potential confounders.Participants included 32,098 lifetime nonsmokers (7,216 men and 24,882 women) enrolled in the Japan Multi-Institutional Collaborative Cohort Study. Passive smoking was assessed using a self-administered questionnaire. The single question about exposure to passive smoking had five response options: "sometimes or almost never," "almost every day, 2 hours/day or less," "almost every day, 2 to 4 hours/day," "almost every day, 4 to 6 hours/day," and "almost every day, 6 hours/day or longer." Hypertension was defined as any of the following: systolic blood pressure ≥140 mmHg, diastolic blood pressure ≥90 mmHg, or use of antihypertensive medication. Multivariate-adjusted odds ratio (OR) and 95% confidence interval (CI) for hypertension were estimated by exposure level to passive smoking using unconditional logistic regression models.The multivariate-adjusted OR for hypertension in those exposed almost every day was 1.11 (95% CI: 1.03-1.20) compared with those exposed sometimes or almost never. The OR for a 1-hour per day increase in exposure was 1.03 (95% CI: 1.01-1.06, Pfor trend = .006). This association was stronger in men than in women; the ORs were 1.08 (95% CI: 1.01-1.15, Pfor trend = .036) and 1.03 (95% CI: 1.00-1.05, Pfor trend = .055), respectively.Our findings suggest importance of tobacco smoke control for preventing hypertension.

Abstract
Chronic kidney disease (CKD) is a public health problem worldwide including Japan. Recent genome-wide association studies have discovered CKD susceptibility variants. We developed a genetic risk score (GRS) based on CKD-associated variants and assessed a possibility that the GRS can improve the discrimination capability for the prevalence of CKD in a Japanese population. The present study consists of 11 283 participants randomly selected from 12 Japan Multi-Institutional Collaborative Cohort Study sites. Individual GRS was constructed combining 18 single-nucleotide polymorphisms identified in a Japanese population. Participants with eGFR <60 mL/min per 1.73 m2 was defined as case (stage 3 CKD or higher) in this study. Logistic regression analysis was used to examine the association between the GRS and CKD risk with adjustment for sex, age, hypertension and type 2 diabetes mellitus. The frequency of individuals with CKD was 8.3%, which was relatively low compared with those previously reported in a Japanese population. The odds ratio of having CKD was 1.120 (95% confidence interval: 1.042-1.203) per 10 GRS increment in the fully adjusted model (P = 0.002). The C-statistic was significantly increased in the model with the GRS, comparing with the model without the GRS (0.720 vs 0.719, Pdifference = 0.008). Increment of the GRS was associated with increased risk of CKD. Additionally, the GRS significantly improved the discriminatory ability of CKD prevalence in a Japanese population; however, the improvement of discriminatory ability brought about by the GRS seemed to be small compared with that of non-genetic CKD risk factors.

Abstract
BACKGROUND Chronic kidney disease (CKD) is a rapidly growing, worldwide public health problem. Recent advances in genome-wide-association studies (GWAS) revealed several genetic loci associated with renal function traits worldwide. METHODS We investigated the association of genetic factors with the levels of serum creatinine (SCr) and the estimated glomerular filtration rate (eGFR) in Japanese population-based cohorts analyzing the GWAS imputed data with 11,221 subjects and 12,617,569 variants, and replicated the findings with the 148,829 hospital-based Japanese subjects. RESULTS In the discovery phase, 28 variants within 4 loci (chromosome [chr] 2 with 8 variants including rs3770636 in the LDL receptor related protein 2 gene locus, on chr 5 with 2 variants including rs270184, chr 17 with 15 variants including rs3785837 in the BCAS3 gene locus, and chr 18 with 3 variants including rs74183647 in the nuclear factor of -activated T-cells 1 gene locus) reached the suggestive level of p < 1 × 10-6 in association with eGFR and SCr, and 2 variants on chr 4 (including rs78351985 in the microsomal triglyceride transfer protein gene locus) fulfilled the suggestive level in association with the risk of CKD. In the replication phase, 25 variants within 3 loci (chr 2 with 7 variants, chr 17 with 15 variants and chr 18 with 3 variants) in association with eGFR and SCr, and 2 variants on chr 4 associated with the risk of CKD became nominally statistically significant after Bonferroni correction, among which 15 variants on chr 17 and 3 variants on chr 18 reached genome-wide significance of p < 5 × 10-8 in the combined study meta-analysis. The associations of the loci on chr 2 and 18 with eGFR and SCr as well as that on chr 4 with CKD risk have not been previously reported in the Japanese and East Asian populations. CONCLUSION Although the present GWAS of renal function traits included the largest sample of Japanese participants to date, we did not identify novel loci for renal traits. However, we identified the novel associations of the genetic loci on chr 2, 4, and 18 with renal function traits in the Japanese population, suggesting these are transethnic loci. Further investigations of these associations are expected to further validate our findings for the potential establishment of personalized prevention of renal disease in the Japanese and East Asian populations.

Abstract
The number of pollinosis patients in Japan has significantly increased over the past 20 years. The majority of genome-wide association studies (GWAS) on pollinosis have been conducted in subjects of European descent, with few studies in Japanese populations. The aim of our GWAS was to identify genetic loci associated with self-reported pollinosis in a Japanese population and to understand its molecular background using a combination of single nucleotide polymorphisms (SNPs) and gene- and pathway-based analyses. A total of 731 and 560 individuals who were recruited as participants of the Japan Multi-Institutional Collaborative Cohort Study participated in the discovery and replication phases, respectively. The phenotype of pollinosis was based on the information from a self-administered questionnaire. In the single-SNP analysis, four SNPs (rs11975199, rs11979076, rs11979422, and rs12669708) reached suggestive significance level (P < 1 × 10-4) and had effects in the same direction in both phases of the study. The pathway-based analysis identified two suggestive pathways (nucleotide-binding oligomerization domain -like receptor and tumor necrosis factor signaling pathways). Both rs1143633 and rs3917368 in the interleukin-1B gene showed associations in the retrace (from pathway to gene and SNP) analysis. We performed single-SNP, gene, and pathway analysis and shed light on the molecular mechanisms underlying pollinosis in a Japanese population.

Abstract
Coffee is one of the most widely consumed beverages worldwide, and its role in human health has received much attention. Although genome-wide association studies (GWASs) have investigated genetic variants associated with coffee consumption in European populations, no such study has yet been conducted in an Asian population. Here, we conducted a GWAS to identify common genetic variations that affected coffee consumption in a Japanese population of 11,261 participants recruited as a part of the Japan Multi-Institutional Collaborative Cohort (J-MICC) study. Coffee consumption was collected using a self-administered questionnaire, and converted from categories to cups/day. In the discovery stage (n = 6,312), we found 2 independent loci (12q24.12–13 and 5q33.3) that met suggestive significance (P < 1 × 10−6). In the replication stage (n = 4,949), the lead variant for the 12q24.12–13 locus (rs2074356) was significantly associated with habitual coffee consumption (P = 2.2 × 10−6), whereas the lead variant for the 5q33.3 locus (rs1957553) was not (P = 0.53). A meta-analysis of the discovery and replication populations, and the combined analysis using all subjects, revealed that rs2074356 achieved genome-wide significance (P = 2.2 × 10−16 for a meta-analysis). These findings indicate that the 12q24.12-13 locus is associated with coffee consumption among a Japanese population.

Abstract
AIM Stroke is associated closely with vascular homeostasis, and several complex processes and interacting pathways, which involve various genetic and environmental factors, contribute to the risk of stroke. Although adrenomedullin (ADM) has a number of physiological and vasoprotective functions, there are few studies of the ADM receptor system in humans. The ADM receptor comprises a calcitonin-receptor-like receptor (CLR) and receptor activity-modifying proteins (RAMPs). We analyzed single nucleotide polymorphisms (SNPs) in the RAMP2 and CLR genes to determine their association with stroke in the light of gene-environment interactions. METHODS Using cross-sectional data from the Japan Multi-Institutional Collaborative Cohort Study in the baseline surveys, 14,087 participants from 12 research areas were genotyped. We conducted a hypothesis-based association between stroke prevalence and SNPs in the RAMP2 and CLR genes based on data abstracted from two SNPs in RAMP2 and 369 SNPs in CLR. We selected five SNPs from among the CLR variants (rs77035639, rs3815524, rs75380157, rs574603859, and rs147565266) and one RAMP2 SNP (rs753152), which were associated with stroke, for analysis. RESULTS Five of the SNPs (rs77035639, rs3815524, rs75380157, rs147565266, and rs753152) showed no significant association with obesity, ischemic heart disease, hypertension, dyslipidemia, and diabetes. In the logistic regression analysis, rs574603859 had a lower odds ratio (0.238; 95% confidence interval, 0.076-0.745, adjusted for age, sex, and research area) and the other SNPs had higher odds ratios for association with stroke. CONCLUSIONS This was the first study to investigate the relationships between ADM receptor genes (RAMP2 and CLR) and stroke in the light of gene-environment interactions in human.

Abstract
BACKGROUND Modifying lifestyle factors such as diet and exercise can reduce the risk of cancer. Psychological stress (PS) might be indirectly associated with cancer because it alters lifestyle factors. However, the relationship among these variables has not been fully investigated. Thus, we examined interactions between self-reported PS (SRPS) and habitual exercise on diet. MATERIALS AND METHODS In all, 5,587 men and 2,718 women were divided into "exerciser" and "non-exerciser" groups, based on whether they exercised regularly, and classified into three SRPS levels: low, moderate and high. Diet was estimated using a validated food frequency questionnaire. Using a general linear model, food and nutrient consumption was estimated for each SRPS level in the 2 exercise groups, and the interactions between SRPS levels and exercise were calculated. RESULTS In women, the intake of pork and beef, low fat milk and yogurt, natto (fermented soybean), carrots and squash, other root vegetables, mushrooms, seaweeds, and wine, along with the nutrients vegetable protein, soluble, insoluble and total dietary fiber, daidzein, genistein, carotene, retinol equivalents, vitamin B2, pantothenic acid, potassium, calcium, magnesium, phosphorus and iron demonstrated significant interaction with SRPS and habitual exercise (p for interaction <0.05). In men, raw and green leafy vegetables and fruit and vegetable juice significantly interacted with SRPS and habitual exercise (p for interaction <0.05). CONCLUSIONS We suggest that certain foods and nutrients, which are thought to have a protective effect against cancer, interact with SRPS and habitual exercise, especially in women. This information is valuable for understanding and improving interventions for cancer prevention.

Abstract
Background: Tea catechins are considered to be important preventive factors of cancer on several organs; however,
the relationships of the actual daily intakes (ADIs) on the preventive effects have not been adequately addressed. We
measured the ADIs of tea catechins as annual averages derived from every their ingested cups recorded by each subject,
and the estimation models were established considering tea origin. Methods: Fifty-nine Japanese men and women
completed four season 3 day weighed dietary records (WDRs) and a food frequency questionnaire (FFQ), and samples
of green, oolong and black teas, ingested during a total 12 days were collected for the analysis. The ADIs of the total and
composed catechins of all tea samples were measured by a high-performance liquid chromatography. The estimation
models for the ADIs (R2: coefficient of determination) based on the WDRs and FFQ were established with multiple
regression analysis using appropriate confounding factors. Results: The ADIs of total catechins and epigallocatechin
gallate (EGCg) were 110 and 21.4 mg/day in men and 157 and 34.7 mg/day in women, respectively. The total catechins
ADIs were positively associated with green tea consumption based on WDRs and FFQ (adjusted R2 =0.421 and 0.341
for men and 0.346 and 0.238 for women, p<0.05 for all, respectively). Likewise, the EGCg ADIs were associated with
green tea intake derived from WDRs and FFQ, respectively. Conclusions: We revealed the ADIs of total catechins
and EGCg as annual averages could establish their estimation models. These provide reference information to clarify
their relationships with cancer risks.

Abstract
The relationship between drinking frequency and amount of alcohol consumption (i.e., drinking habits) and the risk of chronic kidney disease (CKD) remains unclear. We aimed to clarify either a linear or J-shaped dose-response relationship between drinking habits and estimated glomerular filtration rate (eGFR) as a biomarker for identifying individuals at high risk of CKD. In a large-scale cross-sectional study, 403 men and 121 women with an eGFR of 30-60 mL/min per 1.73 m(2) were defined as cases, and 1209 men and 363 women with ≥60 mL/min/1.73 m(2) were randomly extracted as controls (one case subject was matched with three control subjects, matched according to age and season of data collection). We calculated multivariate-adjusted CKD risk and the corresponding mean eGFR according to drinking habits. In men, negative and positive linear relationships with drinking habits were found for CKD risk and mean eGFR (p < 0.001 for all linear terms), respectively, but there were no corresponding J-shaped relationships (not significant for all quadratic terms). In regard to the mean eGFR, however, positive linear relationships were only shown in men in the highest eGFR quartile (p < 0.05 and p < 0.01 for drinking frequency and amount of alcohol consumption, respectively). In women, no association was found. Regarding each drinking habit, we found a positive linear dose-response relationship to eGFR in middle-aged men with an eGFR ≥30 mL/min/1.73 m(2).

Abstract
BACKGROUND In Japan, in comparison with the rest of the world the death rate of lung cancer is low although the smoking rate is relatively high. This is the so-called "Japanese smoking paradox". A healthy diet is proposed to attenuate the risk without quitting smoking. We here examined the relationships between smoking status (SS) and the consumption of food and nutrient in Japan. MATERIALS AND METHODS Totals of 5,587 men and 2,718 women were divided into three (non-smokers, smokers and heavy smokers) and two (non-smokers and smokers) groups, respectively, according to pack-year, which represents the amount of smoking over a long period. Food and nutrient consumption was estimated with a validated food frequency questionnaire. Using general linear models, food and nutrient consumption was estimated for each group in men and women, separately. RESULTS In men, SS was positively related to consumption of rice, 3 alcoholic beverages, carbohydrate, alcohol and other 8 foods/nutrients (p<0.05 for all) and negatively to those of protein animal, fat, fatty acids, dietary fiber, isoflavones and 36 other foods/nutrients (p<0.05 for all). In women, SS was positively associated with intake of 13 foods/nutrients, while being negatively associated with those of rice, energy, dietary fiber, and 14 other foods/nutrients (p<0.05 for all). CONCLUSIONS Our results support lower intake of vegetables and fruits rich in antioxidants, which are thought as preventive factors for many diseases, in smokers.

Abstract
Relationships between human gut microbiota, dietary habits, and health/diseases are the subject of epidemiological and clinical studies. However, the temporal stability and variability of the bacterial community in fecal samples remain unclear. In this study, middle-aged Japanese male and female volunteers (n = 5 each) without disease were recruited from the Sakura Diet Study. Fecal samples and lifestyle information were collected in every quarter and at each defecation for 7 continuous days. Next-generation sequencing of 16S rDNA and hierarchical clustering showed no time trend and intra-individual differences in both fecal sample sets. Significant inter-individual variations in seasonal and daily fecal sample sets were detected for 24 and 23 out of 39 selected dominant genera (>0.1% of the total human gut microbiota; occupation rate >85%), respectively. Intra- to inter-individual variance ratios in 26 and 35 genera were significantly <1.0 for seasonal and daily stabilities. Seasonal variation in fermented milk consumption might be associated with Bifidobacterium composition, but not with Lactobacillus. For most of the dominant genera in the human gut microbiota, inter-individual variations were significantly larger than intra-individual variations. Further studies are warranted to determine the contributions of human gut microbiota to nutritional metabolism, health promotion, and prevention/development of diseases.

Abstract
The aim of this study was to investigate the interaction between psychological stress (PS) and drinking status in relation to diet among middle-aged Japanese men and women in a large-scale cross-sectional study. The study population included 5,587 middle-aged Japanese men and 2,718 middle-aged Japanese women who underwent annual health checkups. The subjects were divided into 2 groups (non-drinkers and drinkers) and classified as having low, moderate, or high self-reported PS levels. Energy-adjusted food and nutrient consumption was assessed with a validated food frequency questionnaire. Using a general linear model, food and nutrient consumption was estimated for each self-reported PS level in the 2 groups (non-drinkers and drinkers) and the interactions between self-reported PS levels and drinking status were calculated. In men, pork and beef; squid, octopus, shrimp, and clams; eggs; mushrooms; Japanese-style sweets; ice cream; bread; Chinese noodles; coffee; and soda as foods and protein, animal protein, fat, animal fat, carbohydrate, monounsaturated fatty acid, polyunsaturated fatty acid (PUFA), n-3 PUFA, n-6 PUFA, cholesterol, vitamin D, vitamin B2, vitamin B6, vitamin B12, niacin, pantothenic acid, magnesium, phosphorus, and zinc as nutrients significantly interacted with self-reported PS levels and drinking status (p for interaction <0.05 for all). No specific interactions were found in women. These findings suggest interactions between PS levels and drinking status with consumption of some foods and nutrients, especially macronutrient intake, in men but not in women.

Abstract
As a part of the development of an alternative to microbiological assay for vitamin B12, we performed a quantitative analysis of cyanocobalamin (CN-cbl) in a National Institute of Standards and Technology Standard Reference Material (SRM 3280) by HPLC. Using this method, the observed value (4.64 microg/g) of CN-cbl in SRM 3280 was found to be in good agreement with the certified value (4.80 microg/g). The accuracy was over 95%, with a corresponding measurement precision value of 5%. To evaluate the applicability of the method on commercial multivitamin tablets, the method was applied to a variety of these samples. The present method has a good accuracy and precision to evaluate CN-cbl with respect to all of the examined tablets.

Abstract
OBJECTIVE Serum 25-hydroxyvitamin D [25(OH)D] is a vitamin D metabolite and a good indicator of vitamin D nutritional status. Low 25(OH)D levels accelerate age-related bone loss in women. The aim of this study was to assess 25(OH)D levels using population-based samples from women in a community in Japan. SUBJECTS AND METHODS Of all 187 adult women living on a solitary island (Niigata, Japan), 150 (80.2%) were enrolled in a cross-sectional study in early June 1998. After excluding 6 subjects who were undergoing treatment for osteoporosis, 144 female subjects were analyzed. Serum 25(OH)D(2) and 25(OH)D(3) were determined by high-performance liquid chromatography. The sum of 25(OH)D(2) and 25(OH)D(3) was calculated, yielding 25(OH)D, for which a concentration of less than 30 nmol/L was defined as vitamin D insufficiency. Demographic data such as age, height, weight, and body mass index (BMI) were also recorded. RESULTS The average age of the subjects was 61.3 years (SD 12.8), ranging from 21 to 87. The average concentrations of 25(OH)D(2) and 25(OH)D(3) were 0.5 nmol/L (SD 3.2) and 64.6 nmol/L (SD 17.6), respectively. The number of subjects with 25(OH)D concentration less than 30 nmol/L was 4 of 149 (2.7%). Serum 25(OH)D concentrations were not significantly correlated with age (r=-0.065, p=0.44l) or BMI (r=0.086, p=0.310). CONCLUSION The present population-based study confirms adequate levels of 25(OH)D and low prevalence of vitamin D insufficiency in Japanese women. Further research should be directed toward darifying which dietary factors determine vitamin D nutrition.

Abstract
PURPOSE To examine how folate status in a body is influenced by oxidative stress. MATERIAL AND METHODS Mice were given total body irradiation (TBI) by X-ray, and changes in the concentration of folate were compared to those in vitamins C and E. RESULTS In a time-dependent study, folate in plasma and bone marrow decreased from 5 h until 120 h post-TBI at 3 Gy. Folate in plasma and bone marrow decreased in a dose-dependent manner at 24 h. Marked decreases of vitamins C and E were also detected in bone marrow, but not in plasma even at 10 Gy of TBI. The susceptibility of plasma folate by irradiation was confirmed by an in vitro exposure study. Neither vitamins C and E nor folate were decreased in the liver by TBI. CONCLUSION It is suggested that folate is vulnerable to oxidative stress, and folate may need to be evaluated, particularly for TBI or radiotherapy.

Abstract
PURPOSE To examine how folate status influences chromosomal damage following X-ray irradiation. MATERIAL AND METHODS In an animal study, mice were fed either a low, basal, or high folic acid diet (0, 2, or 40 mg/kg diet, respectively) for 4 weeks, and then given total body irradiation (TBI) at 0.5 Gy. In a human study, subjects were supplemented with folic acid (800 microg/day) for 2 weeks and their peripheral blood was irradiated at 0.5 Gy in vitro. Chromosomal damage was determined by micronucleus assay. RESULTS In an animal study, TBI-induced chromosomal damage was higher and folate concentration was lower in the bone marrow of the low folic acid group compared to the other two diet groups. The chromosomal damage and folate concentration were comparable between the basal and high folic acid groups. TBI administered to mice decreased folate in the plasma, erythrocyte and bone marrow. In a human study, supplementation with folic acid increased plasma folate, but did not influence either plasma homocysteine or X-ray-induced chromosomal damage in lymphocytes. CONCLUSION Low folate status increases susceptibility to X-ray-induced chromosomal damage, but excessive folic acid supplementation under normal conditions yields no further protection due to folate saturation in the target tissue.

Abstract
We examined the protective effect of dietary folate on benzene-induced chromosomal damage in bone marrow of mice regarding folate levels in diet and tissue. Male mice were fed either a deficient, basal, or high folate diet (0, 2, or 8 mg/kg diet, respectively) for 4 wk followed by a single dose of benzene. Plasma folate levels corresponded to those of dietary intake. Meanwhile, bone marrow, erythrocyte, and liver folate were decreased to 40% in the deficient group and almost saturated in the high group. Plasma homocysteine levels negatively correlated to levels of tissue folate. Chromosomal damage, evaluated by micronucleus assay, was not affected by folate status alone but was markedly enhanced by benzene, particularly in the deficient group (P < 0.05 vs. the basal and high groups). The activities of hepatic drug-metabolizing enzymes did not enhance benzene metabolism in the deficient groups, indicating that enhanced chromosomal damage was solely due to the low folate status. These results suggest that a low folate status can increase the risk of benzene-induced chromosomal damage in bone marrow, but excess folate intake does not enhance protection, as it is saturated in tissue.

Abstract
In a search for substances related to the marked induction of hepatic cytochrome P450 (CYP) by ginkgo biloba extract (GBE), mice were given either GBE (1000 mg kg(-1)) or fractions of GBE for 5 days. The content and activity of CYPs were induced markedly by a bilobalide-rich fraction, but not by flavonoid-rich fractions. The level of induction by the bilobalide-rich fraction was almost the same as that induced by the unfractionated GBE, suggesting that bilobalide is largely responsible for the CYPs induction. To confirm these findings, mice were given various doses of bilobalide (10.5, 21 and 42 mg kg(-1)), or GBE (1000 mg kg(-1), containing bilobalide at 42 mg kg(-1)). Treatment with bilobalide induced CYPs markedly and in a dose-dependent manner, and the level of induction was quite similar between bilobalide (42 mg kg(-1)) and GBE. Treatment with GBE and with bilobalide greatly induced pentoxyresorufin O-dealkylase activity. These findings indicate that bilobalide is the major substance in GBE that induces hepatic CYPs.

Abstract
BACKGROUND Clinical trials have reported the cholesterol-lowering effects of soy protein intake, but the components responsible are not known. OBJECTIVE This meta-analysis was primarily conducted to evaluate the precise effects of soy isoflavones on lipid profiles. The effects of soy protein that contains enriched and depleted isoflavones were also examined. DESIGN PUBMED was searched for English-language reports of randomized controlled trials published from 1990 to 2006 that described the effects of soy protein intake in humans. Eleven studies were selected for the meta-analysis. RESULTS Soy isoflavones significantly decreased serum total cholesterol by 0.10 mmol/L (3.9 mg/dL or 1.77%; P = 0.02) and LDL cholesterol by 0.13 mmol/L (5.0 mg/dL or 3.58%; P < 0.0001); no significant changes in HDL cholesterol and triacylglycerol were found. Isoflavone-depleted soy protein significantly decreased LDL cholesterol by 0.10 mmol/L (3.9 mg/dL or 2.77%; P = 0.03). Soy protein that contained enriched isoflavones significantly decreased LDL cholesterol by 0.18 mmol/L (7.0 mg/dL or 4.98%; P < 0.0001) and significantly increased HDL cholesterol by 0.04 mmol/L (1.6 mg/dL or 3.00%; P = 0.05). The reductions in LDL cholesterol were larger in the hypercholesterolemic subcategory than in the normocholesterolemic subcategory, but no significant linear correlations were observed between reductions and the starting values. No significant linear correlations were found between reductions in LDL cholesterol and soy protein ingestion or isoflavone intakes. CONCLUSIONS Soy isoflavones significantly reduced serum total and LDL cholesterol but did not change HDL cholesterol and triacylglycerol. Soy protein that contained enriched or depleted isoflavones also significantly improved lipid profiles. Reductions in LDL cholesterol were larger in hypercholesterolemic than in normocholesterolemic subjects.

Abstract
10777 Background: Adjuvant hormonal therapy for postmenopausal breast cancer is now one of the most significant therapies in the world. From the results of the ATAC trial and the ITA trial, standard hormonal therapy for postmenopausal breast cancer has changed from tamoxifen to aromatase inhibitor. However concerning the rate of bone-relating complications including bone fracture, osteoporosis, a decrease in bone mineral density (BMD), aromatase inhibitor is reported higher than tamoxifen. According to the 2003 ASCO guidelines on the role of bisphosphonates in women with breast cancer, most women with newly diagnosed breast cancer are at risk of osteoporosis due to either their age or their breast cancer treatment. The Panel recommended an algorithm for patient management to maintain bone health. The purpose of the study is to investigate the efficacy of bisphosphonate for prevention from osteoporosis by aromatase inhibitor in Japanese women with breast cancer. Methods: From 2002 to 2004, we experienced 92 cases of postmenopausal Japanese women who underwent breast cancer operations and take aromatase inhibitor after operations in Tokyo Medical University hospital. We selected two medicines. One is Anastrozole (ArimidexR) as an aromatase inhibitor, and the other is Alendronate (BonalonR) as a bisphosphonate medicine.We investigated the change of BMD, calcium, bone absorption marker like NTX, I-CTP. Results: The value of NTX which patients take Alendronate with Anastrozole decreased about 40% than which patients take Anastrozole alone. Also the rate of bone-relating complications is lower.The mean value of BMD, % YAM, T-score, Z-score is 0.86, 81.0, −1.52, 1.47, respectively. Conclusions: The results suggest the efficacy of bisphosphonate for prevention from bone-relating complications osteoporosis by aromatase inhibitor in Japanese women with breast cancer. No significant financial relationships to disclose.

Abstract
OBJECTIVE To evaluate the effect and safety of treatment with low-calorie formula diet on renal function and proteinuria in obese patients with diabetic nephropathy. DESIGN Prospective study on safety and efficacy of a 4-week low-calorie (11-19 kcal/kg/day) normal-protein (0.9-1.2 g/kg/day) diet partly supplemented with formula diet. SUBJECTS In all, 22 obese patients with diabetic nephropathy (BMI: 30.4+/-5.3 kg/m(2), HbA1c: 7.1+/-1.4%, serum creatinine: 172.4+/-57.5 micromol/l, urinary protein: 3.3+/-2.6 g/day). RESULTS The mean body weight decreased by 6.2+/-3.0 kg. The mean systolic blood pressure, creatinine, blood urea nitrogen, urinary protein, and 8-hydroxydeoxyguanosine decreased significantly by 7.5+/-12.7 mmHg, 41.6+/-23.9 micromol/l, 1.50+/-1.61 mmol/l, 1.8+/-1.7 g/day, and 3.1+/-3.6 ng/mg creatinine, respectively. No patient had increased serum creatinine and urinary protein. Mean creatinine clearance (40.6+/-17.9 to 46.1+/-14.6 ml/s/1.73 m(2)) and serum albumin showed no significant changes. Delta serum creatinine and Delta urinary protein correlated with Delta body weight (r=0.62 and 0.49, respectively) and Delta visceral fat area (r=0.58 and 0.58, respectively), but did not correlate with Delta systolic blood pressure, Delta fasting blood glucose and Delta subcutaneous fat area. CONCLUSION These results suggested that weight reduction using formula diet might improve renal function and proteinuria safely for a short term in obese patients with diabetic nephropathy.

Abstract
We investigated the effects of curcumin, a major antioxidant constituent of turmeric, on hepatic cytochrome P450 (CYP) activity in rats. Wistar rats received curcumin-containing diets (0.05, 0.5 and 5 g/kg diet) with or without injection of carbon tetrachloride (CCl(4)). The hepatic CYP content and activities of six CYP isozymes remained unchanged by curcumin treatment, except for the group treated with the extremely high dose (5 g/kg). This suggested that daily dose of curcumin does not cause CYP-mediated interaction with co-administered drugs. Chronic CCl(4) injection drastically decreased CYP activity, especially CYP2E1 activity, which is involved in the bioactivation of CCl(4), thereby producing reactive free radicals. Treatment with curcumin at 0.5 g/kg alleviated the CCl(4)-induced inactivation of CYPs 1A, 2B, 2C and 3A isozymes, except for CYP2E1. The lack of effect of curcumin on CYP2E1 damage might be related to suicidal radical production by CYP2E1 on the same enzyme. It is speculated that curcumin inhibited CCl(4)-induced secondary hepatic CYPs damage through its antioxidant properties. Our results demonstrated that CYP isozyme inactivation in rat liver caused by CCl(4) was inhibited by curcumin. Dietary intake of curcumin may protect against CCl(4)-induced hepatic CYP inactivation via its antioxidant properties, without inducing hepatic CYPs.

Abstract
BACKGROUND Blood coagulation factor XIII (F-XIII) promotes cross-linking of fibrin during blood coagulation. Impaired clot stabilization in patients with genetic deficiencies of F-XIII is associated with marked pathologies of wound healing. METHODS 60 rats given carbon tetrachloride underwent ileal anastomosis after which they received albumin (Alb animals) or F-XIII concentrate (F-XIII animals) immediately after surgery and daily thereafter until day 2 or 4 and were euthanized on day 3 or 5, respectively, or until day 5 and were euthanized on day 7, 10, or 21. We measured the plasma F-XIII activity and anastomotic tensile strength, followed by immunohistochemical localization of F-XIII subunit A within anastomoses. RESULTS On day 3, there were no significant differences between Alb and F-XIII animals for plasma F-XIII activity and tensile strength, and both groups of animals showed little immunostaining for F-XIII on anastomoses. Plasma F-XIII activities did not differ between Alb and F-XIII animals on day 5 (115.8 +/- 16.8 vs. 137.3 +/- 14.9%). Although the tensile strength in both groups was increased compared with that of day 3, that in F-XIII animals (129.8 +/- 3.3 gf) was significantly higher than that in Alb animals (100.8 +/- 5.3 gf, p = 0.014). F-XIII animals showed de novo collagen fibers and intense immunoreactivity of F-XIII in the extracellular matrix around the anastomoses. Similar differences occurred on day 7 but not days 10 and 21. CONCLUSIONS F-XIII concentrate may accelerate the early healing process of intestinal anastomosis because of the protein's accumulation in situ.

Abstract
In previous papers, we showed that Ginkgo biloba extract (GBE) induced hepatic cytochrome P450 (CYP) activity, in particular pentoxyresorufin O-dealkylase (PROD; corresponding to CYP2B type) in rats, and that GBE influenced the efficacy of co-administered drugs. In this study, to clarify the nature of the induction, we examined the effects of GBE samples from different sources and some major constituents of GBE on rat hepatic CYP in vitro and in vivo. In the study in vitro, eight GBE samples dose-dependently inhibited PROD activity in microsomes prepared from GBE-treated rats, and the inhibitory ratio correlated well with the content of proanthocyanidin in the GBE samples. Moreover, among six GBE constituents examined, proanthocyanidin markedly inhibited the PROD activity. However, administration of two GBE extracts with different proanthocyanidin contents to rats induced hepatic CYP activity, including PROD, to similar extents, and proanthocyanidin alone did not induce PROD activity. Furthermore, GBE samples extracted with both acetone-water and ethanol-water showed similar induction of CYPs in rats in vivo. These results suggest that most GBE samples available in Japan induce CYPs in rats regardless of the preparation method of the GBE, and that proanthocyanidin is not responsible for the induction. Further studies will be necessary to identify the constituent(s) of GBE involved in the induction of CYPs in vivo.

Abstract
The sesquiterpene contents in leaves of wild Rosa rugosa and of sixty-one hybrid rugosas were quantitatively measured by a GC analysis. In this group of samples, the greater the number of glandular trichomes the hybrid rugosas possessed on their leaves, the larger the amount of sesquiterpenes they accumulated. In contrast, those having no leaf glandular hairs contained only a trace amount of sesquiterpene components. The concentrations of bisaborosaol A (1) and carota-1,4-dienaldehyde (2) as representative sesquiterpenes of R. rugosa were positively correlated with the density of the glandular trichomes. Furthermore, an approximately regular correlation was observed between the concentrations of 1 and 2 in most of the sesquiterpene-producing hybrid rugosas, regardless of their productivity. This suggests that a major part of these hybrid rugosas have inherited from R. rugosa the ability to produce two skeletally different sesquiterpenes in parallel with a phenotype to develop leaf glandular trichomes. This investigation also led to discovering 1-dominant (e.g., Amelie Gravereaux and Purple Pavement), 2-dominant (e.g., David Thompson), and other-dominant (e.g., Martin Frobisher) types of sesquiterpene-producing hybrid rugosas.

Abstract
Muscle segments excised from rabbit biceps femoris muscles were treated with detergent sodium dodecyl sulphate to denature cellular constituents, and each was autografted in a 5 cm gap of the sciatic nerve in the same rabbit. Axonal regrowth through the grafts and reinnervation into the host sciatic nerves and muscles were studied morphologically, and electrophysiologically, 4 months after grafting. Regenerating axons accompanied by Schwann cells extended through basal lamina tubes of the grafts into the distal host nerves. Reinnervation of the tibialis anterior muscles by motor nerves was confirmed by recovery of the compound muscle action potentials (CMAP) and the reinnervation of the muscle spindles was demonstrated by electron microscopy. These findings indicated that the basal lamina tubes of denatured muscles were effective scaffolds through which the regenerating nerve fibers grew across as large a gap as 5 cm.

Abstract
The proportion of mortalities from biliary tract cancer, which includes gallbladder and extrahepatic bile duct cancers, is only 5% of all deaths from malignant neoplasms in Japan. Epidemiologists, however, are concerned about the cancer due to its peculiar geographic distribution. In addition, they have also noted the recent decreasing trends in mortality rates, especially among females. The most probable explanation is either a change in the effects of risk factors or the development of abdominal ultrasound sonography and laparoscopic cholecystectomy, or both. Further research should be directed towards an analysis of the causes of this decreasing trend.

Abstract
Nerve regeneration in the central nervous system has been studied by grafting various tissues and cells. In the present study, we demonstrated that choroid plexus ependymal cells can promote nerve regeneration when grafted into spinal cord lesions. The choroid plexus was excised from the fourth ventricle of adult rats (Wistar), minced into small fragments, and grafted into the dorsal funiculus at the C2 level in adult rat spinal cord from the same strain. Electron microscopy and fluorescence histochemistry showed that ependymal cells of the grafted choroid plexus intimately interacted with growing axons, serving to support the massive growth of regenerating axons. CGRP-positive fibers closely interacted with grafted ependymal cells. HRP injection at the sciatic nerve showed that numerous HRP-labeled regenerating fibers from the fasciculus gracilis extended into the graft 7 days after grafting. This regenerating axons from the fasciculus gracilis was maintained for at least 10 months, with some axons elongating rostrally into the dorsal funiculus. Evoked potentials of long duration were recorded at a level ca. 5 mm rostral to the lesion in the rats 8 to 10 months after grafting. These findings indicate that choroid plexus ependymal cells have the ability to facilitate axonal growth in vivo, suggesting that they may be a promising candidate as graft for the promotion of nerve regeneration in the spinal cord.

Abstract
In this cross-sectional study, 91 healthy premenopausal women aged 20-39 years were investigated to determine the effect of physical activities during their teenage years on their current bone mineral densities (BMD). We measured whole-body BMD (WBMD), lumbar BMD (LBMD), and radial BMD (RBMD) with dual energy X-ray absorptiometry (DXA). Using a questionnaire, we asked the women about their physical activities during junior and senior high school and at present. We also asked about their current nutritional status and past and current milk intake. After adjusting for age, body mass index (BMI), current total calorie and calcium (Ca) intake, and milk intake when they were teenagers and at present, we determined that subjects who exercised during extracurricular activities at each of the three periods (during junior and senior high school and at present) had significantly higher WBMD and LBMD (P <0.01, respectively) than did those who did not exercise at those times. Subjects who played high-impact sports at each period had significantly higher WBMD and LBMD than did subjects who played low-impact sports (P <0.05, respectively). Subjects who had exercised regularly from their teenage years to the present had significantly higher BMD at all sites than BMD in other subjects after adjusting for the potential confounders described above (P <0.05, respectively). Our data suggest that continuous exercise beginning in junior high school, especially high-impact sports, may be associated with greater current bone mass. It is important to incorporate adequate exercise beginning in the teenage years to lower one's future risk for osteoporosis.

Abstract
During an investigation of the sesquiterpene phases and contents in leaves of several Rosa rugosa hybrids (hybrid rugosas), Martin Frobisher and Vanguard were found to accumulate a large amount of (+)-4-epi-alphabisabolol (1) as a single constituent. Although glandular trichomes of Martin Frobisher on the leaves are dense, this R. rugosa hybrid produces none of the carota-1,4dienaldehyde (2) or bisaborosaol A (3) that are both found as representative sesquiterpenes of the carotane and bisabolane classes, respectively, in a glandular trichome exudate of wild-type R. rugosa. Compound 1 was also apparent as a nearly single constituent detectable by GC in the leaf constituents of Vanguard possesses sparse glandular trichomes on the leaf. Martin Frobisher and Vanguard had likely lost their capability to form carotane-type sesquiterpenes and had also lost their activity to oxygenate the C-7 allyl methyl carbon of compound 1 to convert 3. The presence of (+)-4-epi-alphabisabolol-accumulating R. rugosa hybrids is significant when considering the sesquiterpene biogenesis of Rosa rugosa.

Abstract
The effects of bacterial masses upon the drug resistance of neighboring bacteria were investigated. The experiments were performed with plastic Petri dishes divided into two identical compartments. A growing mass of Bacillus subtilis (signal emitter cell) in one compartment exerted enhancing effects upon the erythromycin and streptomycin resistance of Bacillus carboniphilus (signal recipient) cells, sparsely seeded in the other compartment, through the plastic wall and the air. These effects of the growing mass of cells are attributed to the emission of "sonic" signals.

Abstract
This report describes two cases of Philadelphia chromosome-negative (Ph(-)) non-Hodgkin's lymphomas (NHLs) recognized in patients with chronic phase Ph-positive (Ph(+)) chronic myelogenous leukemia (CML). Lymph node biopsy of patient 1 was initially diagnosed as diffuse large B cell non-Hodgkin's lymphoma (NHL, T cell rich variant), but at relapse showed immunoblastic features with a marked decrease of admixed lymphocyte components. Patient 2 presented with thickened parietal pleura which revealed a CD30-positive anaplastic large cell lymphoma showing null cell phenotype and genotype with abundant admixed neutrophils and lymphocytes. At the time of lymphoma diagnosis, the patients had CML for 33 and 10 months, respectively. DNA obtained from bone marrow cells at the time of lymphoma diagnosis showed BCR/ABL gene rearrangements by both Southern blot analysis and reverse transcription polymerase chain reaction (RT-PCR), but lacked both immunoglobulin and T cell receptor gene rearrangements. BCR gene rearrangement and BCR/ABL fusion gene were also identified in lymph node and pleural biopsies by Southern blot and RT-PCR analysis, respectively. However, both biopsy specimens also contained reactive lymphocytes and neutrophils, and no fusion signals between BCR and ABL genes were identified in the hyperdiploid lymphoma cells of either case by fluorescence in situ hybridization (FISH). These data suggest the lymphoma cells in both cases were not genetically associated with BCR/ABL. Therefore, these cases were not diagnosed as an extramedullary localized blast crisis in CML, but as Ph(-) NHLs. This represents the first definitive demonstration of peripheral B cell lymphoma occurring by a separate genetic pathway, lacking BCR/ABL, in patients with Ph(+) CML. A review of the literature identified two different subtypes of malignant lymphomas arising in patients with an antecedent or concurrent diagnosis of CML. The most common are T cell lymphomas displaying an immature thymic phenotype, while peripheral B cell lymphomas are more rare. Our study shows, however, that 'Ph(+) NHL' occurring in CML or acute lymphocytic leukemia (ALL) may represent an unrelated neoplasm, even if standard cytogenetic analysis reveals a Ph(+) chromosome, and that FISH is required to confirm whether a localized lymphoid neoplasm is either a true extramedullary localized blast crisis or genetically distinct neoplasm.

Abstract
Ecological correlation analysis was made between the source of drinking water and standardized incidence ratios (SIRs) of malignant neoplasms registered in Niigata, Japan. The purpose of this study was to find out some clues for generating a working hypothesis that the contamination of drinking water with environmental chemicals especially of endocrine disrupting chemicals in big rivers may be related to the occurrence of cancers. Sources of drinking water in the year 1974 were classified into two categories; one from the Shinano and Agano and their down-stream rivers, and the other from small rivers flowing into these big rivers, rivers originating from the mountain areas, underground and reservoirs (The other group). After excluding registered cases under 20 years of age, the registry data (1992-94) were sub-divided into two categories according to the source of drinking water. The SIRs were calculated by using two different standard populations; Niigata total and "The other group". All of the sites were examined in the former standard. In the latter case, however, 12 and 9 sites in males and females, respectively were selected based on the assumption that the expected numbers in each age group totaled 5 or over when there were more than 200 registered patients as a total. Concerning the judgment for the significant association in the former standard, we considered the presence of positive associations when both of the SIRs in the two categories were significantly different from the Niigata total population (p < 0.05 by chi 2 test). Of the 33 sites in males, the following sites were correlated with the source of drinking water; tongue, colon, rectum, gallbladder, etc., prostate, kidney, etc. and all sites. Of 35 sites in females, those were the colon, gallbladder, etc., bronchus and lung, breast, corpus uteri, thyroid and all sites. Of the 12 and 9 respective sites subjected to the second analysis, positive associations were observed in the following: esophagus, colon, rectum, liver, gallbladder, etc., bronchus and lung, prostate, bladder and all sites in males, and colon, rectum, gallbladder, etc., bronchus and lung, breast and all sites in females. Final conclusion, however, should be waived until the consistency of association can be confirmed by using more reliable incidence data, because the difference in the death certificates only (DCO) rate between the two groups might have played as a bias. The use of mortality data may be an alternative way to evaluate the present findings in terms of the consistency of association.

Abstract
There have been few reports describing otomycosis in association with compromised hosts. So we report a neutropenic acute myeloid leukemia (AML) patient complicated with otomycosis caused by superinfection. A 51-year-old male was admitted because a third relapse of AML in March 1998. Two years ago, he was diagnosed as having chronic otitis media involving the VII cranial nerve due to Pseudomonas aeruginosa coinciding with AML. Then, he had suffered from a right-sided earache and otic discharge in accord with every myelosuppression, which improved on treatment with otic administration of ofloxacin. After 1 course of induction chemotherapy, he developed a spiking fever with severe earache and otic discharge at a nadir period of WBC. Ear swab cultures yielded Aspergillus niger and yeast-like fungi. So, he was treated with intravenous administration of amphotericin B (AMPH-B): initial dose was 5 mg/day and was gradually increased to 30 mg/day. Thereafter, the otic symptoms subsided and never recurred. Subsequently, he was given another antifungal agent, itraconazole. Although induction chemotherapies resulted in failure, he did not suffer otic symptoms until his death due to cerebral bleeding in January 1999. For neutropenic patients without rapid hematological improvement, we recommend intensive antifungal therapy as the first-line of therapy for otomycosis rather than local therapy.

Abstract
Sciatic nerves were excised from 3 beagle dogs about 5 h after their sacrifice, treated three times by freezing and thawing, and stored in physiological saline for 3 months at -20 degrees C until used. Nerve segments 5 cm in length prepared from these stored nerves were transplanted to the common peroneal nerve in the right hindlimb of beagle dogs. Sixteen beagle dogs in total were used, in four treatment groups of two pairs each studied at 1 and 3 months. Five-hundred microliters basic fibroblast growth factor (bFGF) of two different concentrations (10 micrograms/300 microliters and 100 micrograms/300 microliters) which were impregnated in 0.5 ml gelatin hydrogels was applied around the sutured allografts. Autografting was also done in 4 beagle dogs, with no bFGF application. One month after the grafting, no regenerating nerves extended beyond the middle of the transplant in any of the allografts, except in the autografts in which a number of regenerated (myelinated) axons were present. Three months after the grafting, an abundance of myelinated axons was found at the middle of the graft: the numbers of axons per 10(4) micron 2 were 22.6 in the autografts and 10.6, 10.4 and 19.2 in the allografts treated with no bFGF, low-dose bFGF, and high-dose bFGF, respectively. Regenerating axons extended into the host nerve: the numbers of myelinated axons at the level 1.5 cm distal to the distal suture were 35.7, 0.9, 3.8, and 12.1 per 10(4) micron 2 in the above respective order. Although it was inferior in quality to the autograft, peripheral nerve regeneration was extensive in the distal nerve using freeze-thawed and bFGF-treated allografts at 3 months. Electromyography showed that the peroneus longus muscle responded to the electrical stimuli given at the site proximal to the transplant in all four groups. These data indicate that a 5-cm acellular nerve segment containing Schwann cell basal laminae can be used successfully as an allograft without any immunosuppressants and that exogenously applied bFGF can improve nerve regeneration by enhancing the growth of regenerating axons.
