Due to the attractive benefits with regard to bone health, digestion, and hydration, carbonated water consumption have rapidly grown over the past few years. However, the acidic drink has latent potential for enamel erosion. The most experimental studies about the enamel erosion have focused on the carbonated beverages with sugar and artificial sweeteners. Here, we determined the enamel erosion potential by commercially available carbonated waters with bovine teeth. The erosion was verified by pH value, calcium concentration, and scanning electron microscope. Then plaque accumulation by bacterial adhesion was determined on the enamel erosion surface to measure roughness. In the present study, we observed that the increased calcium content after being immersed in carbonated waters result from the overall enamel erosion. There were no significant differences between general carbonated waters and mineral waters for erosive capacity. Therefore, commercially available carbonated waters are potentially erosive. In addition, oral bacteria strongly adhered to the erosive enamel surfaces thereby facilitating the development of dental plaque. Thus, it is urgently necessary to provide food safety information on the carbonated water as acidic drink to prevent the enamel erosion.

상처회복과정은 염증, 재상피화, 그리고 기질의 재형성등을 포함한 포괄적인 생물학적 반응이다. 생물학적 분류체계에서, 회복능력은 매우 다양한데, 일반적으로 하등동물이 고등동물에 비교해 단순하며 뛰어난 것으로 알려져 있다. 따라서, 하등동물들을 이용한 실험모델은 상처회복과 치유의 기작을 연구하는데 자주 이용되고 있다. 양서류를 이용한 피부 상처회복과정 동안의 조직화학적 특성들을 규명하기 위하여 한국산 무당개구리(Bombina orientalis)를 이용하였다. 1일, 10일 그리고 16일의 조직에서 점액물질이 활발하게 분비되는 것을 확인하였으며, PAS (periodic acid shiff)와 Alcian blue (pH 2.5) 반응에 강하게 염색되었다. PTAH(phosphotungstic acid hematoxylin) 염색을 통하여 상처 후 10일 조직에서 상처주변의 진피층에서 콜라겐의 합성이 증가하는 것을 확인하였다. 또한, 세포의 유사분열의 시점을 확인하기 위한 MG-P (methyl green pyronin)염색에서 초기에는 3시간과 6시간에 강한 염색반응을 관찰하였고, 이는 23일과 27일 조직에서도 동일한 패턴으로 이어졌다. The wound healing is very complex biological processing including inflammatory, reepithelialization and matrix construction. According to the biological systematic category, the ability of the healing is very different. Generally healing ability of the lower animal group has been known more excellent compared to its higher group. Therefore, lower animals have been used as the experimental model to explore the mechanism of the wound healing or repair. To verify histochemical characteristics of the wound healing, we have used skin of the frog (Bombina orientalis) as known common amphibian. At day 1, 10, and 16, the mucous substance was very actively synthesized and strong positive by PAS and Alcian blue (pH 2.5). Day 10 after wounding, margin of the wound was gradually strong positive by PTAH staining for detection of collagen synthesis. At 3 to 6 hour and day 23 to 27, we have found the cell division was active through the MG-P staining, in which the concentration and division of DNA in nucleus was green to deep blue color.

We conducted a study to access the effectiveness of glove and washing hands for the prevention of microbial contamination during the dental clinical practice. Microbial numbers at unwashed hands and gloves were 9.938×103 (CFU)/ml, those at washed with soap were 9.44×103 CFU/ml And those at washed with a typical liquid soap including disinfectant, Dettol (Reckitt Benckiser, Slough, SL1 3UH, UK) were 6.58×102 CFU/ml. In case of unwashed hand and hand washing with soap had similar microbial numbers and in case of hand washing with Dettol showed a rapid decrease of microbial number. Hand washing with Dettol was effective to prevent microbial contamination than hand washing with soap. Also microbial numbers in all case wearing gloves decreased. It showed effectiveness of gloves for prevention of microbial contamination. In addition to microbial numbers showed a tendency to increase from 3 hours on wearing gloves, the change of new gloves after 3 hours on wearing is necessary to minimize the danger of microbial contamination.

본 연구는 2009년 국민건강영양조사 자료를 이용하여 우리나라 성인에서 다양한 혼란변수를 보정한 후 현존자연치아수와 COPD와의 연관성을 알아보고자 하였다. 40세 이상성인 3,107명을 대상으로 구강검진과 폐기능검사를 시행하여 다음과 같은 결론을 얻었다. 첫째, 폐기능검사에 의한 COPD 유병률은 11%였다. 현존자연치아수를 0∼19개군, 20∼27개군, 28개군으로 나누었을 때, COPD의 분포는 현존자연치아수가 0∼19개인 군에서 21.0%로 가장 높았다. 둘째, COPD는 65세 이상군, 남자, 교육수준이 낮을수록, 정상적인 BMI를 갖는 군, 고혈압군에서 높았다(p<0.001).셋째, 인구사회학적 특성, 사회경제적 위치, 건강관련행태, 구강건강 및 행태, 전신건강상태를 보정한 다중로지스틱 회귀분석에서는 현존자연치아수 20∼27개군(OR, 1.90)과 0∼19개군(OR, 3.93)에서 COPD와 연관성을 보여, 현존자연치아수가 적을수록 COPD의 위험이 증가함을 확인하였다. 특히 치주질환과 COPD의 중요한 위험요인인 흡연상태에 따른 층화분석결과, 현재흡연군에서만 모든 치아를 가지고 있는 군에 비해 0∼19개 치아를 가진 군에서 OR이8.90배 높은 결과를 보여 강한 연관성을 보여주었다(OR,8.90; 95% CI, 2.53∼31.33). 본 연구 결과를 통해 현존자연치아수는 COPD와 연관성이 있음을 확인하였다. The aim of this study was to evaluate whether the number of existing permanent teeth is associated with chronic obstructive pulmonary disease (COPD) in a representative sample of Korean adults. Data from 3,107 subjects who participated in the 2009 Korea National Health and Nutrition Examination Survey were examined. The dependent variable was COPD and the independent variable was the number of existing permanent teeth. Spirometry results were classified into three groups (normal pattern, restrictive pattern, and obstructive pattern) by trained technicians. We used dichotomized COPD variables (no vs. yes). The number of existing permanent teeth was evaluated by oral examination and divided into 3 groups (0∼19, 20∼27, and 28). Demographic factors (age group and sex group), socioeconomic status (education and income), health behaviors (smoking and drinking), oral health and behavior (frequency of toothbrushing; periodontitis; decayed, missing, filled, permanent teeth index; and denture status), and general health status (body mass index, diabetes mellitus, and hypertension) were included as confounders in the analysis. Bivariate analysis and multivariate logistic regression analyses including confounders were applied, and all analyses considered a complex sampling design. Stratified analysis was performed by smoking status. After controlling for various confounders, there was a significant association between the number of existing permanent teeth and COPD (odds ratio [OR], 1.90; 95% confidence interval [CI], 1.20∼3.00 for the 20∼27 group; OR, 3.93; 95% CI, 1.75∼8.84 for the 0∼19 group). The association was more significant in current smokers (OR, 8.90; 95% CI, 2.53∼31.33). Our data indicate that the number of existing permanent teeth was independently associated with COPD, especially in current smokers. Further longitudinal research is needed to determine whether oral health promotion plays a role in the improvement of lung function and prevention of COPD.

This research is the preliminary data of the patients who have got PCI(percutaneous coronary intervention) procedure and applied RDE(recreational dance exercise) to compare and analyse their BP and the effect on arterial stenosis and arterial stiffness to prevent coronary artery disease and to find effective treatment after PCI procedure by proving the effect of RDE. As a result, there was specific body composition changes in only between the group of weight(F=4.567, p=.049) but before and after the exercise. Between the group of B P, SBP(F=12.730, p=.003), DBP(F=6.244, p=.025), pulse pressure(F=9.142, p=.009) showed a notable difference. For MTG(medical treatment group) only pulse pressures(t=-2.281, p=.048) noticeably increased before and after the exercise. And E MG(exercise and medical treatment group) showed decrease in SBP(t=5.110, p=.001), DBP(t=3.451, p=.011), pulse pressure(t=4.148, p=.004). The change of arterial stiffness showed the difference in only right ba-PWV(F=4.978, p=.041), and the changes occurred before and after the exercise were right(t=2.558p=.038) and left(t=2.930, p=.022) in EMG. The change of arterial stenosis didn`t show differences between the groups, but left ABI in MTG was increased(t=-2.909, p=.017) before and after the exercise. In conclusion, participating RDE after PCI procedure is giving confirmatory positive effect on the patients` BP and arterial stiffness. So with the results, RDE could be recommended not only for managing aftereffects but also as an effective way to have improvement on cardiovascular disease.

김준석(Jun Suk Kim),서홍석(Hong Seog Seo),오동주(Dong Joo Oh),임도선(Do Sun Lim) 대한약학회 1993 약학회지 Vol.37 No.1

Brovincamine is a selective cerebral vasodilator that was apparently produced via a slow calcium blockade. Brovincamine has been shown to increase ATP production and glucose and oxygen consumption in brain, improving energy metabolism. Also brovincamine inhibited platelet aggregation induced by ADP and collagen in vivo and in vitro via an increase of cAMP concentration, promoting therapeutic effects on cerebral circulatory disorders. So we investigated and represented the clinical effects and safety of brovincamine in patients with cerebral stroke. Thirty patients of cerebral stroke that was older than 2 months, who were 22 cases of cerebral infarction, 6 of cerebral embolism that originated from cerebral infarction, 6 of cerebral embolism that originated from cardiac diseases, and 2 of cerebral embolism that originated from cardiac diseases, and 2 of cerebral hemorrhage, were administered of 20 mg of oral brovincamine three times daily for 8 weeks. Improvement rates of each symptom after 8 week administration were 30.8% for subjective symptoms, 76% for psychiatric symptoms and 65.6% for neurologic symptoms. In final global improvement rates, much improvement was 10%, improvement was 23.3% slight improvement is 36.7%, and no change was 30%. So global improvement rate including slight improvement was 70%. As for side effects, there were 3 cases of mild gastrointestinal symptoms, but there were no other subjective side effects and significant fluctuation in laboratory examination. Conclusively throughout the present study, brovincamine is judged to be well tolerated and effective in patients with cerebral stroke.
