The dental infections have been increased due to the widespread overuse and exposure to antibiotics. One of the well-known pathogens is S. aureus The pathogenic properties of S. aureus is associated with the virulence gene. The objective of this study is to investigate the distribution of virulence gene of S. aureus which may contribute to the prevention and treatment of bacterial infections. 54 strains of S. aureus were separated from saliva taken from 129 outpatients diagnosed with periodontitis from Jun. to Dec., 2010 in Seoul. 44 (46.6%) and 13 (31.7%) strains of them were obtained from 88 and 41 outpatients from the S and E dental clinics, respectively. Then, the distribution of virulence gene and genetic diversity were analyzed with the PCR technique. The result of the S. aureus isolates possessed coagulase gene and showed six polymorphism types 390~470 bp (1.8%), 550~633 bp (3.7%), 630~714 bp (9.3%), 715~795 bp (20.4%), 796~876 bp (40.7%) and 877~957 bp(22.2%) due to variable numbers of tandem repeats present within the gene. In this study it will be anticipated that this study can contribute to establish efficiently the countermeasure about the prevention and treatment of antibiotic bacterial infections.

Purpose: Activation of the innate immune system and chronic low-grade inflammation are thought to be involved in the pathogenesis of atherosclerosis and also thought to be associated with type 2 diabetes and its complications. As a receptor for bacterial lipopolysaccharide and heat-shock proteins, Toll-like receptor 4 (TLR4) is one of the central regulators of the immune response. Recent studies have reported an association between TLR4 polymorphisms and diabetes and its complications in Caucasian populations. Materials and Methods: In this study, we analyzed the association between TLR4 gene polymorphisms in patients with features of type 2 diabetes and healthy controls in Korea. Two polymorphisms of the TLR4 gene (Asp299Gly and Thr399Ile) were examined in 225 diabetic patients and 153 healthy controls using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and single-strand conformation polymorphism (SSCP). Results: No Asp299Gly or Thr399Ile mutations were detected in any of the 378 subjects. Seven subjects from each group who had slightly different SSCP patterns were selected for sequencing, but we found no TLR4 polymorphisms on Exon3. The Asp299Gly and Thr399Ile TLR4 gene polymorphisms were absent in both groups, which was similar to the results for Japanese and Chinese Han subjects. Conclusion: Our data and other Asian data suggest that a racial difference can be found in the frequency of the TLR4 polymorphism.

김연선,박신애 인간식물환경학회 2016 인간식물환경학회지 Vol.19 No.6

This study was conducted to find the effectiveness of a horticultural activity program for mothers to improve the relationship between mother and child. The target participants were comprised of 60 mothers who have a child aged between 4 to 7 years, and they were divided into the experimental group (n=30) and the control group (n=30). Those of the experimental group attended 6 sessions of the horticultural activity program in total (one session per week, 90 minutes on average), and those of the control group did not participate in the program. A survey on parenting stress, self-esteem, parenting efficacy and emotional empathy was conducted before and after the program. Its results indicated that the participants of the experimental group showed statistically significant improvements in the parenting stress level (associated with the characters of children, the relationship with them, and learning expectation). Their self-esteem also showed statistically significant improvements from perspectives of self-abasement, relationships with others, leadership and popularity, and assertiveness and anxiety. Their parenting efficacy including efficacy as a parent; anxiety and frustration as a parent; and interest and attention to parental roles showed statistically significant improvements, but there was no statistically significant difference in emotional empathy including emotional sympathy and empathic concern. In addition, the results of the satisfaction survey conducted among the mothers of the experimental group after the program indicated that their satisfaction of the overall program, the time required for a session, and the frequency of the program was high. In this study, it was found that positive changes could be realized through the horticultural activity program for the improvement of the relationship between mother and child by modifying relevant factors. It is expected that the participants of the study may experience more positive improvements if they can join horticultural activities with their child later, and it is necessary to develop programs that can engage parents in other environments based on the results of this study.
