Purpose We designed this study for the purpose of determining the relationship between periodontal disease activity and PLBW, using the evaluation of probing pocket depth, loss of attachment, gingival index, gingival crevicular fluid amount and subgingival microflora. Methods A total of 100 volunteer mothers(mean age 30.44) at the Department of Obstetrics and Gynecology Seoul National University Hospital were selected for this study.Pregnancy outcomes were categorized into cases and controls in two ways. our definition was based on the following; Group 1 : Any PLBW cases Vs. All NBW controls Group 2 : PLBW cases Vs. NBW controls A periodontal exam was performed on the Ramfjord( #16, 21, 24, 36, 41, 44) teeth and Clinical evaluation consisted of probing pocket depth, loss of attachment, gingival index and gingival crevicular fluid amount. Subgingival plaque samples were collected by three sterile #35 paper points. The total number of anaerobic colonies and aerobic bacteria were enumerated after incubation. Antisera to P. gingivalis, P. intermedia, A. actinomycetemcomitans were produced in white rabbits with live whole cells suspensions. The specific fluorescent bacteria obtained by immunofluorescence and total cell counts obtained by dark-field microscopy were counted on four fields. The percent of each specific microorganism in the total cell count was determined. Results Any PLBW and PLBW cases showed significantly greater probing depth and attachment loss than all NBW and NBW controls. Cases group had significantly increased anaerobic bacterial counts compared with control group and no differences in the other microbes. This study confirmed that periodontal disease is a statistically significant risk factor for PLBW by investigating clinical parameters and subgingival plaque analysis.

약용식물 6종을 메탄올로 추출한 다음, n-hexane층을 DMSO에 녹여 항산화 활성을 측정·비교하여 기능성 소재인 천연 항산화제로써의 활용 가능성을 조사하였다. DPPH를 이용한 라디칼 소거능 실험에서는 250 μg/mL 농도에서 보골지가 대조군인 ascorbic acid에 비해 높은 유리기 소거능에 의한 항산화 활성을 나타냈다. 농도 500 μg/mL 에서는 ascorbic acid가 가장 높은 항산화 활성을 보였다. ABTS 유리기 소거능 실험에서는 농도 증가에 따른 항산화 활성이 DPPH assay와 상반된 결과를 나타냈고, 특히 보골지의 항산화 활성이 대조군인 ascorbic acid보다 유의적으로 높게 나타났다. DPPH 라디칼, ABTS 유리기 소거능 실험 결과 공통적으로 우수한 것으로 조사 된 약용 식물은 반지련, 보골지이며 500 μg/mL 이상의 농도에서 ascorbic acid와 유사한 90% 활성을 보였으며 750 μg/mL 농도에서는 ascorbic acid 보다 우수한 유리기 소거 활성을 보였다. 따라서, 반지련과 보골지는 항산화 활성이 우수하므로 천연 식물소재로 이용하기에 적합하며, 천연물의 추출 부위, 용매, 추출 조건에 따라 다양한 항산화 활성 능력을 기대 할 수 있으므로 천연 항산화제로서의 응용 가능성 또한 있을 것으로 사료된다. The objective of this study was carried out in order to evaluate the antioxidative activities of n-hexane fractions from medicinal herbs. Certain parts from 6 species of edible and medicinal herbs were extracted with methanol. Radical scavenging activity of the n-hexane fractions against DPPH and ABTS radicals were observed to be high in Psoralea corylifolia, and Scutellsria barbata it also significantly increased (p<0.05). For a comparison of the effect of various concentration of fractions, as the concentration of treatment increased, the antioxidative effects on radical scavenging activity also oncreased; yet it was not significant. The antioxidative effect of medicinal plants was dependent on the concentration but was not significant. Therefore, these results indicate that edible wild plants, such as Psoralea corylifolia, and Scutellsria barbata may be useful as potential antioxidant sources for improving the human antioxidant defense system against disease.

Zea Mays L. has been known to be effective for improving tissue health and Magnoliae cortex to have effective antibacterial and antimicrobial activity against pathogenic microbes. The purpose of this study was to examine the antimicrobial effects of Zea Mays L. and Magnoliae cortex extract mixtures on periodontal pathogens(Prevotella intermedia, Actinobacillus actinomycetemcomitans, Porphyromonas gingivalis, Streptococcus mutans )and to examine the effects on human gingival fibroblast cellular activity. Zea Mays L. and Magnoliae cortex extracts and their mixtures were prepared with various mixing ratios (0.5:1, 1:1, 1.5:1, 2:1). These extracts were loaded to periodontal pathogen cultured petri dish for antimicrobial test and also loaded to cultured human gingival fibroblast for cellular activity test. Each test was repeated 3 times and data were analyzed by one-way ANOVA with 95% confidence level. Mixture of these two extracts showed greater amount of inhibition area on periodontal pathogen and more improved gingival fibroblast activity as Zea Mays L. ratio reduced. So, mixture ratio 0.5:1 (Zea Mays L. : Magnoliae cortex) group showed statistical significance in antimicrobial activity and cellular activity among various mixtures(p < 0.05). In conclusion, 0.5:1 (Zea Mays L. : Magnoliae cortex) mixture possessed best gingival fibroblast cellular activity and antimicrobial activity toward periodontal pathogens.

Background: Asthma is characterized by airway hyperresponsiveness, eosinophilic inflammation, airway mucus hypersecretion, and elevated serum immunoglobulin E (IgE). IL-13 is an important cytokine in the pathogenesis of asthma through the production of IgE, stimulation of bronchial epithelial mucus production, and smooth muscle hyperreactivity. Previous studies have shown that the polymorphisms in IL-13 gene are associated with asthma, atopy, or total IgE. Objective: We investigate whether the polymorphism Arg 110Gln within the IL-13 gene is associated with asthma, atopy, serum total IgE, asthma severity and airway hyperresponsiveness in adult asthma. Method: One hundred fifty-five asthmatic adults and 147 non-asthmatic healthy adults were enrolled. Asthma phenotype and bronchial responsiveness to methacholine were determined by the same physician. IL-13 Arg110Gln polymorphism was genotyped using PCR-RFLP assay. Result: Genotype frequency of IL-13 Arg110Gln polymorphism was significantly different between asthmatic patients (P=0.021), especially between atopic asthma (P=0.024) and controls, and was associated with elevated levels of serum total IgE (P=0.009), asthma severity (P=0.026), pulmonary function (P=0.017), and airway hyperresponsiveness (P=0.025) in patients with asthma. Conclusion: IL-13 Gln110 variant may be an asthma susceptibility gene in Korean adults. In addition, IL-13 Gln110 variant is associated with elevated levels of serum total IgE and severity of asthma.

Magnetite nanoparticles encapsulated with biodegradable polymer [poly(D,L-lactide-co-glycolide), PLGA] were prepared by an emulsification-diffusion method. To investigate the effect of type of organic solvents on the mean particle sizes of obtained composite particles, different organic solvents [ethyl acetate (EA), propylene carbonate (PC) and acetone (ACE)] were used with a stabilizer [didodecyl dimethyl ammonium bromide (DMAB)]. The particle size of nanoparticles was observed by the dynamic light scattering method. When EA and PC as partially water-soluble solvents were used, small composite nanoparticles below 80 ㎚ were obtained, while large composite nanoparticles above 330 ㎚ were prepared for ACE as a fully water-soluble solvent.
