  • This study consists of two sections to figure out the relationship between autistic features and empathizing-systemizing traits. For the first section, the research involved 355 university students to measure their EQ, SQ-R and AQ. As a result, it is found that AQ was negatively correlated to EQ, and D score(relative difference between EQ and SQ-R of the individuals), but it was not significantly related to SQ-R. It means that the subject has high AQ if he has relatively lower EQ than SQ-R. For the second section, the subjects were divided into two groups based on their AQ score; the subjects who had a tendency of autism and the subjects who did not. The test measured how these two groups were different in terms of facial expressions' recognition according to the tendency of autism, facial expression presenting areas(whole face, eyes-alone, mouth-alone) and different types of emotions(basic and complex emotions). As a result, the subjects who had a tendency of autism were lower at judging facial expressions than the subjects who did not. Also, the results showed that the subjects judged better on the condition of basic emotions more than complex emotions, the whole face more than eyes-alone and mouth-alone. Especially, for the eyes-alone condition, the subjects who had a tendency of autism were lower at judging facial expressions than the subjects who did not. This study suggests that empathizing traits and facial expressions' recognition are related to the tendency of autism.

  • Background: Chronic rhino-sinusitis and persistent allergic rhinitis is often cited as risk factor for developing adenoid hypertrophy or adenoiditis, but this relationship has not been studied extensively. In this study, we evaluated the mucosal barrier, squamous changes of ciliated epithelium, IgA secretion and BCL-6 expression in adenoids, and adenoid size. Methods: Six children with allergic rhinitis and sinusitis, nine children with only allergic rhinitis, nine children with only sinusitis and six children without any history of allergic rhinitis and sinusitis were enrolled. H-E stain of adenoid for squamous metaplasia, immunohistochemical study of adenoid for IgA and BCL-6, cytokeratin stain for evaluation of mucosal barrier and lateral view X-ray for adenoid size were performed. ANOVA test was used in the analysis and data showing p value of less than 0.05 were considered significant. Results: The number of ciliated cells had tendency to be decreased and squamous metaplasia had tendency to be increased in three experimental groups (p>0.05). Deterioration of mucosal barrier had tendency to be detected in three experimental groups than control group (p>0.05). BCL-6 had tendency to be increased and IgA secretion had tendency to be decreased in three experimental groups (p>0.05). There is no difference in adenoid size between three experimental groups and control group. Conclusion: Despite the expectation that adenoid would be affectecd by allergic rhinitis and rhino-sinusitis, we found no evidence for influence of adenoid immunity.

  • The purpose of this study is to expression pattern of melanogenesis associate genes on cultured melanocyte layer cells in Korean Brindle Cattle(Dark, Brindle and Yellow) were analyzed to evaluate the effects of sex hormones on the control of melanogenesis pathways. Korean Brindle Cattle(Dark, Brindle and Yellow) melanocyte in the skin cells was collected. after the addition of estrogen and testosterone, the culture was analyzed for expression of cell activity and melanin genes for 72 hours. For the analysis of estrogen in different coat color other than the melanogenesis-related genes it is increasingly yellow showed low expression. in particular, the cells of the brindle coat color is low active and expression of genes. However, the testosterone was low, the expression of cell activity inhibiting MMP-2. the expression of melanin genes actually showed a tendency to increase gradually, which is testosterone compared with the estrogen to be considered that affect the skin cell layer brindle coat color. In this study, stimulation with estrogen triggered the inhibition of MC1R of the melanocyte in brindle coat color, but testosterone is induced MC1R in melanocyte. Therefore, considered the eumelanin or phaeomelanin activation are controlled caused by differential expression of sex hormones on melanocyte in Korean Brindle Cattle.

  • In the commercial space, the modern consumers want to consume not only product but also culture. Thus, the modern commercial space tries to induce the customer's concern and purchase to the differentiated design. The introduction of this 'the natural element' delivers the pleasure and stability to the consumer buying process and availability is enlarged. Therefore, the purpose of study is gain that expression and characteristic method of the natural element in the commercial space. The detailed study method are as follows. First, the study looks into the natural element expression tendency in the modern space. Second, the expression type of the natural element was classified as 'Reappearance', 'Transformation', and 'Fuse' based on the preceding research. And according to the content of the expression type, subdivided method of 'Inclusion' and 'Replication' of 'Reappearance' and method of 'Imitation' and 'Association' of 'Transformation' and method of 'Juxtaposition' and 'Combine' of 'Fuse'. Third, the result of analyze the characteristic of expression of the natural element of the besides the commercial space case 20 place is as follows. First, 'Inclusion' of 'Reappearance' introduced the external scenery or planned garden as the inside through the opening. 'Replication' is used for decorative purposes or functional purposes as the natural element. 'Imitation' of 'Transformation' imitated the form, pattern, and color of the natural element and was mainly expressed in the wall and objet. The method of 'Association' expressed the concept of the natural element for the whole of the space and a portion of the wall and objet repetitively. As for 'Juxtaposition', mixture of 'Reappearance' had a good visual effect, because it can be obtained the external-internal nature. As for 'Combine', mixture of 'Replication' and 'Imitation' was the most common method. Thus, the study results are expected to be utilized as base date in designing the commercial with development of the natural element application method.

  • We investigated the prognostic value of pituitary tumor transforming gene 1 (PTTG1) expression according to clinicopathological features among localized or locally advanced prostate cancer cases receiving hormone therapy. A retrospective study involved 64 patients receiving combined androgen blockade treatment was performed. PTTG1 expression was determined by immunohistochemical staining using initial needle biopsy specimens for diagnosis. Associations of PTTG1 with various clinicopathological features and disease-free survival were examined via uni- and multivariate analyses. No association between PTTG1 expression and clinical T stage, Gleason score, pretreatment PSA levels, risk groups was found (p =0.682, 0.184, 0.487, 0.571, respectively). Univariate analysis revealed that increased PTTG1 expression, T3 stage and high risk group were associated with increased risk of disease progression (p =0.000, 0.042, and 0.001), and high PSA level had a tendency to predict disease progression (p =0.056). Cox hazard ratio analysis showed that PTTG1 low expression (p =0.002), PTTG1 high expression (p =0.000) and high risk group (p =0.0147) were significantly related to decreased disease-free survival. In conclusion, PTTG1 expression determined by immunohistochemical staining in needle biopsy specimens for diagnosis is a negative prognostic factor for progression in localized or locally advanced prostate cancer receiving hormone therapy.

  • Objectives: Angiogenesis is the process of new blood vessel development from preexisting vessel. The growth of tumor is dependent on angiogenesis. This study was aimed to determine the role of the VEGF expression and MVD(microvessel density) in salivary gland tumors and to analyze the correlation between the expression of VEGF/MVD, and clinical manifestation. Material and Methods: We analyzed the expression of VEGF and average MVD and neo-MVD in the 57 cases of salivary gland tumors by immunohistochemistry. Results: VEGF expression was higher in malignant tumors than in benign tumors. Average and neo-MVD were not different in benign tumor and malignant tumor. There was a tendency of positive correlation between VEGF expression and MVD but it was not statistically significant. Stage, T stage and recurrance rate were not correlated with VEGF expression, average-MVD and neo-MVD. Expression of VEGF, average-MVD and neo-MVD were significantly increased in Warthin's tumor compared with pleomorphic adenoma. Conclusion: Overexpression of VEGF has an important role in malignant salivary gland tumors.

  • Objectives: Odontogenic keratocysts (OKCs) have a tendency to recur and possess an aggressive nature. the aim of the present study was to evaluate cytokeratin (CK) expression patterns as a method for the differentiation between dentigerous cysts (DCs) and OKCs, as their histomorphologic appearance are often indistinguishable. Materials and Methods: Formalin-fixed, paraffin-embedded tissue sections of 43 OKCs and 38 DCs were immunohistochemically analyzed with i-solution in a quantitative manner in order to evaluate the immunoreactivity of CK 10, 16 and 17. Results: CK 10 expression was evident in 79.1% of OKCs but found in only 18.4% of DCs (P<0.05), and CK 10 expression was observed to occur more frequently in OKCs (mean 25.45%) than in DCs (2.19%) (P<0.05). The expression of CK 16 was evident in 79.1% of OKCs but found in only 7.9% of the DCs (P<0.05) and CK 16 expression was observed to occur more frequently in OKCs (mean 4.33%) than in the DCs (0.61%) (P<0.05). The expression of CK 17 was evident in 88.4% of OKCs but seen in only 15.7% of the DCs (P<0.05) and CK 17 expression was observed to occur more frequently in OKCs (mean 31.11%) than in the DCs (2.37%) (P<0.05). Conclusion: The immunohistochemical detection of CK 10, 16 and 17 can be utilized as a valuable biomarker for use in distinguishing between OKCs and DCs, which have clinically significant differential diagnoses.

  • Purpose: Bone marrow has long been a source of primary cells. This study was performed to evaluate the effects of age and sex on the cellular viability and expression of stem cell markers of mRNA and on the protein expression of bone marrow stem cells (BMSCs) derived from healthy donors. Materials and Methods: Stem cells were isolated from human bone marrow and plated in culture plates. The shape of the BMSCs was observed under inverted microscope. Quantitative cellular viability was evaluated using a Cell-Counting Kit-8 assay. The expression of stem cell surface markers was tested and a series of quantitative real-time polymerase chain reaction (qRT-PCR) and Western blot was performed to evaluate the expression in each group. Result: The shapes of the cells at 20s, 30s, and 50s were similar to each other. No significant changes in cellular viability were noted among different age groups or sex groups. The BMSCs expressed CD44, CD73, and CD90 surface markers but did not express CD14 and CD34. There were no noticeable differences in CD surface markers among the different age groups. The expressions of CD surface markers were similar between men and women. No significant differences in the secretion of vascular endothelial growth factors (VEGFs) were noted at Day 3 between different age groups. qRT-PCR regarding the expression showed differences between the age groups. However, Western blot analysis showed a decrease in expression but did not reach statistical significance (P>0.05). Conclusion: This study clearly showed no significant differences in shape, cell viability, expression of stem cell surface markers, or secretion of human VEGF among different age groups. However, western blot analysis showed a tendency of age-related decrease which did not reach statistical significance. Collectively, autologous or allogeneic BMSCs should be meticulously applied to obtain optimal results regarding age and sex.

  • Epidermal cells produce a panel of antioxidants as well as cytokines after UVB irradiation, which counteract reactive oxygen species, however, how these antioxidants might regulate melanogenesis is unclear. An important constituent of the cellular antioxidant buffering system which controls the redox state of proteins is thioredoxin (TRX), a 13-kD protein that catalyzes thiol-disulfide exchange reactions, regulates activation of transcription factors, and possesses several other biological functions similar to cytokines. TRX suppressed the UVB-induced production and secretion of $\alpha$-melanocyte stimulating hormone ($\alpha$-MSH) and of adrenocorticotropic hormone (ACTH), and also suppressed proopiomelanocortin (POMC) mRNA expression by normal human keratinocyte (KC)s. Further, L-cysteine, N-acetyl-cysteine, $\alpha$-tocopheryl ferulate showed suppressive effect on UVB-induced POMC mRNA expression. However, TRX released from UVB-irradiated KCs stimulated melanogenesis by up-regulating MSH receptor expression and its binding activity in melanocyte (MC)s. UVB-induced KC derived cytokines such as IL1, IL6, and ET1 upregulated MSH-receptor binding ability as well as MCl-R mRNA expression in cultured normal human MCs. MCl-R has a tendency to be upregulated by UVB-induced KC-derived cytokines as well as by direct UVB irradiation. These results suggest that antioxidants such as TRX suppresses UVB induction of POMC, but in the case of MCl-R, this gene can be mainly in the trend of upregulation by UVB-induced KC-derived factors including TRX.
