Abstract
BACKGROUND AND OBJECTIVE The aim of this study was to compare the susceptibility of nonperiodontopathic and periodontopathic bacteria to major defense mechanisms for bacterial clearance in gingival sulcus. MATERIAL AND METHODS Twenty strains of 13 oral bacterial species were studied for their susceptibility to phagocytosis by human neutrophils and to the antimicrobial peptides LL-37 and human beta defensin-3. The minimum inhibitory concentrations of LL-37 and human beta defensin-3 were determined by a liquid dilution assay, and susceptibility to phagocytosis was examined by a flow cytometric phagocytosis assay. RESULTS The minimum inhibitory concentrations of LL-37 and human beta defensin-3 varied greatly, depending on the strain and species. Although a significant difference between the non- and periodontopathic groups was not observed, the red-complex bacteria were more resistant to LL-37 than the others (p=0.004). The susceptibility of oral bacteria to phagocytosis was quite variable, depending on the species but not on the strains. The periodontopathic bacteria, especially Actinobacillus actinomycetemcomitans and the red-complex triad, were more resistant to phagocytosis than were the nonperiodontopathic bacteria (p=0.0003). In addition, bacteria resistant both to antimicrobial peptides and to phagocytosis were more common in the periodontopathic group. CONCLUSION Our results indicate that immune evasion may contribute to the pathogenicity of some periodontopathic bacteria.

Abstract
11088 Background: Nipple-sparing mastectomy (NSM) and immediate reconstruction has recently been accepted as a new surgical procedure that provides good cosmetic results, although it is necessary to establish oncological safety. We reported our experience to evaluate indications, technique, results, and complications of NSM. Methods: Between 1999 and 2005, medical records of 113 patients with breast cancer undertaken NSM at the Asan Medical Center were analyzed retrospectively. Median age of the patients was 40 years and complications were assessed 3 months later postoperatively. Results: For preoperative indications of NSM, mulifocal or multicentric cancers were 60 cases (53.1%), diffuse microcalcifications on MMG were 27 cases (23.9%), failure of breast conserving surgery due to tumor involvement of resection margin were 12 cases (10.6%), central located small cancers were 11 cases (9.7%). Immediate reconstruction methods were 85 cases (75.2%) in TRAM and 28 cases (24.8%) in direct implant. Intraoperative frozen section biopsy for evaluation of tumor involvement at the NAC showed accuracy of 100%. Pathologic tumor size were 24 cases (21.2%) in Tis, 56 cases (49.6%) in T1, 33 cases (29.2%) in T2, respectively. Lymph node status showed 81 cases (71.7%) in N0, 24 cases (21.2%) in N1, 7 cases (6.2%), and one case (0.9%) in N3, respectively. During 20 months of the median follow-up, four patients developed recurrences; one local recurrence (subcutaneous), two (lung, brain) distant failures, and one local and distant failure. The rate of major NA necrotic complication was 14.6%, but all cases were improved with conservative management. 91.7% of patients were satisfied with their cosmetic results. Conclusions: Although the presented study does not establish conclusion with regard to oncological safety due to short follow-up period, the procedure of NSM with intraoperative pathologic assessment of the subareola tissue, and immediate reconstruction is a reasonable option for a selected patients. Good candidates for NSM are patients unsuitable for breast conservation either for multicentric or multofocal cancers, or because of extensive microcalcification, or involvement of resection margin during breast conserving surgery. No significant financial relationships to disclose.

Abstract
AIMS To investigate the probiotic properties of Bacillus polyfermenticus SCD such as their adherence to Caco-2 cells and anticarcinogenic effects on human colon cancer cells and rat colon cancer carcinogenesis. METHODS AND RESULTS The cell surface hydrophobicity and cell agglutination of B. polyfermenticus SCD was 64.04 +/- 1.25% and 297.3 +/- 8.7 mg ml(-1), respectively. This strain was strongly adherent to Caco-2 cells. Bacillus polyfermenticus SCD was also found to inhibit the growth of colon cancer cells in a dose-dependent manner as detected by the MTT assay. After 10 weeks of B. polyfermenticus SCD supplementation with 3 x 10(6) CFU day(-1) in F344 male rats, dimethylhydrazine-induced aberrant crypts and preneoplastic lesions decreased by 40% compared with the control rats. CONCLUSIONS Bacillus polyfermenticus SCD has strong adherent properties in the colon, and anticarcinogenic effects in vitro and in vivo. SIGNIFICANCE AND IMPACT OF THE STUDY These new findings on the characteristics of B. polyfermenticus SCD will be valuable in the evaluation of this commercial probiotic. Also, B. polyfermenticus SCD can be useful for the inhibition of colon cancer cells as an ingredient of medicinal foods or new drugs.

Abstract
In this paper, we proposed the regression model which could estimate unspecified people's systolic blood pressure (SBP) conveniently and continuously and checked its accuracy through clinical experiments. The method for estimating each individual SBP by using only pulse transit time (PTT) has been studied, but it is difficult to estimate unspecified people's SBP with the method using only PTT. Thus we researched several physical characteristic parameters which might affect blood pressure (BP) with the standard that we can measure them easily and conveniently, chose valid physical characteristic parameters through a clinical testing and correlation analysis, and made the regression model using PTT and valid physical characteristic parameters for estimating unspecified people's SBP. Comparing the result of the proposed method with American National Standards Institute of the Association of the Advancement of Medical Instrument (ANSI/AAMI), we know that the proposed regression model gives an acceptable result.

Abstract
beta-Amyloid precursor protein binding protein 1 (APP-BP1) was previously identified based on its binding to the carboxyl terminal of beta-amyloid precursor protein. In this report, we have discovered that a mutation of dAPP-BP1 (Drosophila ortholog of APP-BP1) hinders tissue development, causes apoptosis in imaginal disc cells, and blocks the NEDD8 conjugation pathway. We show that dAPP-BP1 specifically binds the intracellular domain of APP-like protein (APPL). The dAPP-BP1 mutation partially suppresses the abnormal macrochaete phenotype of Appl(d), while overexpression of dAPP-BP1 causes abnormal macrochaetes. When APPL is overexpressed, the normal bristle pattern in the fly thorax is disturbed and apoptosis is induced in wing imaginal discs. APPL overexpression phenotypes are enhanced by reducing the level of dAPP-BP1. APPL overexpression is shown to inhibit the NEDD8 conjugation pathway. APPL-induced apoptosis is rescued by overexpression of dAPP-BP1. Our data suggest that APPL and dAPP-BP1 interact antagonistically during Drosophila development.

Abstract
The squid (Loligo pealei) byproduct composed of heads, viscera, skin, fins, and small tubes was subjected to hydrolysis at 55 degrees C and natural pH (6.8) using endogenous proteases. Squid hydrolysate was characterized during the course of hydrolysis for changes in the degree of hydrolysis, viscosity, electrophoretic pattern of proteins and peptides, and amino acid and fatty acid profiles. The change in viscosity can be used to monitor the progress of protein hydrolysis up to the molecular mass of 26.63 kDa. The 2 h hydrolysis resulted in a 2-fold increase in the total free amino acids and yielded hydrolysate with protein molecular mass of < or =45 kDa having feed attractability and good amino acid and fatty acid profiles with high contents of essential amino acids and fatty acids. Such hydrolysis-induced changes can make squid byproduct hydrolysate a good source of aquaculture feed ingredient, especially for a starter diet for larval fish.

Abstract
To determine incidence of invasive Haemophilus influenzae type b (Hib) disease in a defined population of Jeonbuk Province, Korea, children <5 years were evaluated in prospective, population-based surveillance of invasive bacterial diseases using standardized methods for patient referral, clinical evaluation and laboratory testing (optimized culture, latex agglutination, polymerase chain reaction). Vaccine utilization was assessed with vaccination histories of patients in surveillance, monthly data on Hib vaccine distribution and a coverage survey of clinic patients in study population. From September 1999 to December 2001, 2176 children were evaluated for possible meningitis, 1541 had no cerebrospinal fluid (CSF) findings of meningitis, 605 had CSF abnormalities (suspected bacterial meningitis) but no pathogen identified; six patients had probable Hib meningitis and eight had confirmed Hib meningitis. The annual suspected bacterial meningitis incidence was 258.4/100,000 <5 years and the probable/confirmed Hib meningitis incidence was 6.0/100,000 <5 years. Pneumococcal meningitis incidence was 2.1/100,000 <5 years and Group B streptococcal meningitis incidence was 0.17/1000 live births. A total of 69,589 Hib vaccine doses were distributed during the study. Hib vaccine coverage was negligible initially but increased to 16% (complete Hib immunization) and 27% (partial immunization) in final months of study. Suspected bacterial meningitis incidence was high but proven invasive Hib meningitis incidence was low. Hib was leading cause of bacterial meningitis yet bacterial pathogens were identified in only 4% of abnormal CSF. These findings may reflect truly low incidence, presumptive antibiotic treatment, partial Hib immunization, or incomplete clinical evaluations. Given the apparent Hib meningitis burden in Jeonbuk Province, additional studies to describe other invasive Hib syndromes, Hib-associated mortality and disability, and economic impact of Hib disease will be useful to guide public health decisions regarding routine Hib vaccine introduction.

Abstract
BACKGROUND Vasoactive intestinal peptide (VIP) is released by stimulation of nonadrenergic noncholinergic (NANC) inhibitory nerves. In order to evaluate the function of VIP in jejunal isografts, we examined the enteric nerve responses in isografted rat jejunum compared with normal jejunum. METHODS Orthotopic entire small bowel transplantation (SBT) with portocaval drainage was performed from Lewis rats to Lewis rats. Grafted tissue specimens were obtained 130 days after SBT (n = 8). As controls, normal segments of the jejunum were obtained from nontransplanted Lewis rats (n = 20). A mechanograph was used to evaluate in vitro jejunal responses to electrical field stimulation (EFS) of the adrenergic and cholinergic nerves before and after treatment with various autonomic nerve blockers and VIP. RESULTS The isografted jejunum was more strongly innervated by excitatory nerves, especially NANC excitatory nerves, than the normal jejunum (P <.05). VIP mediated relaxation reactions of NANC inhibitory nerves in the normal but to a lesser extent in the isografted jejunum (P <.05). CONCLUSIONS The increased NANC excitatory nerves and the decreased effects of VIP in mediating NANC inhibitory nerves may largely relate to the peristaltic abnormalities seen in the isografted LEW rat jejunum.

Abstract
Biomass fuel is the most common energy source for cooking and space heating in developing countries. Biomass fuel combustion causes high levels of indoor air pollutants including particulates and other combustion by-products. We measured indoor air quality in 23 houses with a wood burning stove in rural residential areas of Costa Rica. Daily PM2.5, PM10 and CO concentrations, and particle size distribution were simultaneously measured in the kitchen. When a wood burning stove was used during the monitoring period, average daily PM2.5 and PM10 concentrations were 44 and 132 microg/m3, respectively. Average CO concentrations were between 0.5 and 3.3 ppm. All houses had a particle size distribution of either one or two peaks at around 0.7 and 2.5 microm aerodynamic diameters. The particulate levels increased rapidly during cooking and decreased quickly after cooking. The maximum peak particulate levels ranged from 310 to 8170 microg/m3 for PM2.5 and from 500 to 18900 microg/m3 for PM10 in all houses. Although the 24-h particulate levels in this study are lower than the National Ambient Air Quality Standards of PM2.5 and PM10, it is important to note that people, especially women and children, are exposed to extremely high levels of particulates during cooking.
