This study investigated the effect of nutritional improvement of 1-5 year children participated in NutriPlus program. The program was carried out at Public health Center, Daedeok-gu, Daejeon from March 2009 to April 2011. The subjects were selected among applicants for low-income family financing of the government and included 90 children and their parents. they were divided into 2 groups (less than 6 months and more than 6 months of participation in the study). We analyzed the effects of NutriPlus program and nutrition education in both study groups. The results of this study were summarized as follows: The number of children with less than 10th percentile in height and weight and weight for height was decreased. The anemia prevalence rate was reduced from 64.4% to 8.9%. NAR value of subjects increased for energy, protein, calcium, iron, vitamin A, riboflavin, niacin and vitamin C. The education program improved knowledge and attitude of the parents. In nutrition knowledge according to the income level, there were greater changes in the group of less than 100% compared to the subsistence. In nutrition attitude according to the education level, there were greater changes in the group of middle school graduates than in high school graduates or college graduates. There were no difference between less than 6 months group and more than 6 months group in improvement of hemoglobin level, anthropometric data and nutrients intakes. Based on these results, we conclude that providing supplementary food to children and nutrition education brought positive effects on growth of the children.

The purpose of this study was to evaluate the effect of proportional thickness of various reline materials on the transverse strength of denture base. The denture base resin used in this study was Vertex RS (Dentimex Zeist., Holland). The reline resins used were Tokuso rebase normal set (Tokuyama Corp., Japan), Rebaron (GC Corp., Japan), KoolinerTM(GC INC., U.S.A). New trulinerTM(Harry J. Bosworth Co., U.S.A). The bulk specimens with 2.5mm thickness of denture base were prepared as the control group. Group 1 was fabricated with 2.0mm thickness of denture base and 0.5mm reline material, group 2 with 1.5:1.0mm. group 3 with 1.0:1.5mm, group 4 with 0.5:2.0mm composition. Measurements of transverse strength were taken for each specimens. The results were as follows: 1. Regardless of the reline resin type, the transverse strength of denture base was decreased after reline procedure. 2. The transverse strength according to the reline resin type was decreased in the following order : Rebaron, Tokuso rebase, Kooliner, and then New truliner and there was a significant difference among the reline materials (P<0.05). 3. The strength of the relined denture base generally decreased as the proportional thickness of the denture reline material increased. These results suggest that increasing the proportional thickness of the reline material progressively decreased the strength of the relined denture base. Thus, the denture base should not be unnecessarily altered during the reline procedure.

To delineate the individual role of follicular dendritic cells (FDC) and T cells at each stage of GC B cell differentiation at the clonal level and to analyze the signals required for the differentiation, we developed an experimental model using an FDC line, HK and a lymphoma cell line, L3055 for centroblasts. Phenotypic analysis of L 3055 revealed its origin of GC and the homogeneity. L3055 cells undergo spontaneous apoptosis when cultured in the absence of HK cells. L3055 cells proliferate continuously in the presence of HK cells, while they differentiate into a population with the phenotype of centrocytes after stimulation with CD40 ligand (CD 40L) plus IL-2, IL-4 and IL-10. L3055 undergo anti-Ig-mediated apoptosis, which is not protected by HK but by CD40L and the cytokines. These experimental results suggest that FDC provide signals for the survival and rapid proliferation of centroblasts and T cells trigger the differentiation of centroblasts into centrocytes.

Allergic contact dermatitis is a prototype of delayed hypersensitivity reaction. Langerhans cells, keratinocytes and T lyrnphocytes play major roles in the pathogenesis of allergic contact dermatitis. We observed Langerhans cells and keratinocytes in contact sensitized epidermal sheets of mice and performed mixed epidermal cell lymphocytes reaction with normal epidermal cells and contact sensitized epidermal cells to determine the lymphocyte stimulating capacity of contact sensitized epidermal cell. We obtained following results : 1. The Langerhans cells were decreased in number and morphologically damaged in contact sensitized epidermis. 2. Ia antigen expression on keratinocytes was detected in almost all contact sensitized epidermal sheets. 3. The allogeneic lymphocyte stimulating capacity of contact sensitized epidermal cells was greater than that of normal epidermal cells. 4. The allogeneic lymphocyte stimulating capacity of contact sensitized epiderrnal cells was lost after treatment of epidermal cells with anti Ia antibody and complement. From these results, it is conceivable that the contact sensitized epidermal cells can amplify the immune reactions by stimulating the lynphocytes which are infiltrated in contact sensitized epidermis.

The Polyporaceae is a chaotic mass of genera having poroid hymenophores in the Aphyllophorales. To classify the Polyporaceae into more natural groups, phylogenetic analyses were performed using nuclear small subunit ribosomal DNA sequences. Thirty-six species from the families of the Polyporaceae, the Hymenochaetaceae, the Ganodermataceae, the Corticiaceae, the Bondarzewiaceae, the Meruliaceae, the Steccherinaceae and the Lentinaceae were phylogenetically compared. By performing maximum parsimony analysis, seven phylogenetically meaningful groups were identified and discussed. The hyphal system, presence or absence of clamps, and the type of rot were found as important characters in defining the groups. Each group was phylogenetically significant enough to be a core member of each family when the Polyporaceae was split into smaller and more natural families.

The ultrasonography is a very useful diagnostic procedure in obstetric & gynecologic mass. so we anlayzedtotal 153 cases of pelvic ultrasonogram with pathologic diagnoses. The results were as follows: 1. The ages ofpatients were distributed from 16 to 70 years-old, and the third decade was the most prevalent. 2. Of 153 cases,the ovarian masses were 85 cases, the tubal ones were 49 cases, and the uterine were 19 cases. 3. Of 85 ovarianmasses, physiologic ovarian cysts were 44 cases, and cystic teratoma were 14 cases. Of 49 tubal masses, tubalpregnancies were 35 cases and the most prevalent. Of 19 uterine masses, leiomyomas were 11 ases and the mostprevalent. 4. Of 153 cases, the echo-complex masses were 103 cases, the cystic ones were 34 cases, and the solidones were 19 cases. 5. The characteristic findings of frequent masses were as follows: (1) The physiologic ovariancysts were 44 cases, and show mainly cytic or pure cystic masses in 42 cases. (2) The ectopic pregnancy were 36cases, and show echo-complex masses in 21 cases, and cul-de-sac fluid echo in 22 cases. (3) The cystic teratomaswere 1 cases, and reveal mainly cystic or pure cystic masses in 10 cases, and calcification with posterioracoustic shadowing in 6 cases. (4) The uterine leiomyoma were 11 cases, and reveal solid mass with abnormaluterine contour in 8 cases. (5) The malignant or borderline malignant lesions were 6 cases. (6) Of 153 cases, thepathologic diagnosis was possible in 98 cases(64.1%).

Pigmented Bowen's disease (PBD) is a rare variant of Bowen's disease(BD). Most of the reported cases showed pigmented patches or thin plaques. Thus its clinical manifestations may simulated other various pigmented skin lesions. We experienced 2 cases of PBD in patients with multiple BD developed after taking Korean proprietary pills (KPP, "Hwan-Yak"), which were suspected to contain certain amount of arsenics. Both patients also showed arsenical keratosis on their palms and soles. The darker pigmentation of the PBL led us to differentiated them from melanoma.
