It is known that the periodontal disease is caused by infection of inner oral bacteria as a suffering disease to human mankind for a long time. It can make the various clinical symptoms such as gingiva, bleeding, formation of periodontal pocket, loss of attached gingiva, collapse of alveolar bone and halitosis, and is known to the major contributor of loss of teeth. This study investigated the growth restraint effect of Camellia sinensis and Casia tora. As a result of study, the minimum restraint concentration of standard microbe on F. nucleatum for extracts from C. sinensis showed 2.5, 0.63 and 1.25 mg/ml, respectively and minimum restraint concentration of clinical separation microbe on F. nucleatum for extracts from C. sinensis showed 2.5 and 5.0 mg/ml. The minimum restraint concentration of standard microbe and clinical separation microbe, respectively. Meanwhile, the minimum restraint concentration of standard microbe and clinical separation microbe on F. nucleatum for extracts from C. tora showed 2.5 and 2.5-5.0 mg/ml, respectively. The minimum restraint concentration of standard microbe and clinical separation microbe for P. intermedia, P. nigrescens, P. gingivalis, and P. endodontalis showed above 5.0 mg/ml for standard microbe and above 5.0 mg/ml for clinical separation microbe, respectively. As a result of investigating the cell toxicity for each extracts, extracts from C. sinensis does not showed the toxicity for the cell below the concentration of 2.5 mg/ml, but it showed toxicity for the cell above concentration of 2.5 mg/ml and it decreased the existence ratio for the cell. Meanwhile, in the case of C. tora, it increased the multiplication ratio below the concentration of 1.25 mg/ml compared to the subject group and it decreased gradually the multiplication ratio that the growth ratio for the cell is increased better than subject group. As a result of this study, extracts from C. sinensis was more effect on the growth restraint effect against periodontopathogens than extracts from C. tora and is proven that it is possible for use as a oral mouthrinsing liquids in the near future. On the basis of results of this study, it is judged that the study for reaction mechanism and discrete clinical test for implementation should be needed.

Pelvic inflammatory disease (PID) is a disease that affects young, sexually active, reproductive age women. Most pathogens are Chlamydia trachomatis and Neisseria Gonorrheae transmitted sexually. One of serious acute complication of PID is tubo-ovarian abscess (TOA) that involves the fallopian tube, ovary and adjacent structures (eg, bowel, pelvic peritoneum). The microbiology of TOAs is polymicrobial with anaerobic organisms and causal organisms of PID. Common anaerobic organisms are Peptostretococcus spp, Bacteriodes spp, Prevotella spp, Escherichia coli and aerobic streptococci. Treatment is necessary to admission for intravenous broad-spectrum antibiotics and surgery is often reserved for patients with suspected rupture or patients who fail to respond to antibiotics. So, we reported this case found pelvic abscess due to ruptured tube-ovarian abscess.

이 연구의 목적은 유치와 영구치의 법랑질에 자가 산부식 접착제 적용 전 부가적인 산부식 시간을 달리 하였을 때, 전단결합강도에 미치는 영향을 알아보기 위함이다. 각각 65개의 발거된 건전한 유치와 영구치 협, 설면 법랑질 시편을 제작하고 두 종류의 자가 산부식 접착제를 적용하였다. 실험군은 Clearfil SE bond, Adper Prompt L-pop으로 처리한 두 개 군으로 나누고, 이를 다시 산부식 시간에 따라 여섯 군(0, 5, 10, 15, 20, 30초)으로 분류하였다. 대조군으로는 total-etching system인 Multi-purpose plus를 사용하였다. 접착제 처리면을 복합레진으로 충전하고 24시간 경과 후 전단결합강도를 측정하고 Mann-Whitney test와 Kruskal-Wallis test를 사용하여 통계분석 하였다. 결과는 자가 산부식 접착제를 적용한 군은 유치, 영구치 모두에서 total etching system에 비해 낮은 전단 결합강도를 보였다. 자가 산부식 접착제 사용 군내에서 산부식을 추가로 시행하였을 때 유치와 영구치 모두에서 결합강도가 증가하였으며, 10초 이상 산부식을 시행한 경우 결합력의 차이는 없는 것으로 나타났다. 유치와 영구치간 결합력의 차이는 인정되지 않았다. 결론적으로, 자가 산부식 접착제의 법랑질에 대한 전단결합강도는 유치, 영구치 모두에서 10초 이상의 부가적 산부식이 결합력의 증가에 유리하게 작용하는 것으로 나타났다. The aim of this study was to evaluate the bonding ability of two self etch systems to human primary and permanent enamel and the effect of additional acid etching time. Exfoliated, caries free human primary molar(n=65) and permanent molar extracted (n=65) were used. prepared enamel specimens were randomly divided into 2 test groups and a control group. The control group(n=10) were treated with 35% phosphoric acid gel and Scotchbond Multi-purpose adhesive. Experimental groups(self-etching systems) were subdivided into 6 groups(each n=10) according to additional etching time(0s, 5s, 10s, 15s, 20s, 30s). The result were as follows : 1) The shear bond strengths of the self-etching adhesives(Clearfil SE Bond, Adper Prompt L-pop) without additional etching were lower than control group(Scotch Bond Multipurpose). 2) Between the same self-etch adhesive groups, additional etched groups showed higher shear bond strength 3) There was no significant difference between primary and permanent enamel. In conclusion, bond strength of self-etch adhesives to enamel could be increased with additional etching.

최경숙,장경립,임이종,김순한,정영기,이태호 동의대학교 기초과학연구소 1997 基礎科學硏究論文集 Vol.7 No.1

The strain producing bioemulsifier was isolated from soil samples. The isolated strain was identified as the genus Acinetobacter through its morphological, cultural and physiological characteristics. The highest emulsification activity and stability by Acinetobacter sp. BE-254 was observed after 5 days of cultivation in the culture medium containing n-hexadecane 4%, NaNO₃0.2%, KH₂PO₄0.01%, MgSO₄·7H₂O 0.01%, CaCl₂0.01%, and yeast extract 0.01%. The optimum pH and temperature for bioemulsifier production were pH 7.0 and 30℃, respectively. Furthermore the most of bioemulsifier was produced during the exponential growth phase, and this suggested that the bioemulsifier production was growth-associated. The bioemulsifier showed good emulsification activity on various emulsifying substrates such as hydrocarbons, edible oils, and petroleum fractions.

어린이 영구치에 나타난 국소적 치아 이형성증의 관리

이형숙,김재문,김신,정태성 大韓小兒齒科學會 2008 大韓小兒齒科學會誌 Vol.35 No.4

국소적 치아 이형성증(Regional Odontodysplasia)은 치아 경조직에 비교적 드물게 나타나는 발육성 장애로 치열궁의 특정 사분악에 국한되어 나타나며 이환치 경조직의 모든 구성요소가 발육 부전이나 석회화 부전을 보인다. 국소적 치아 이형성증에 대한 장기적 치료와 관리를 위해서는 여러 분야에 걸친 체계적 접근이 요구되며,치료 계획은 환자의 저작기능과 심미성의 회복,정상적인 수직고경과 공간의 유지,악골의 정상적인 성장과 이환치의 맹출관리를 도모할 목적으로 수립되어야 한다. 본 증례보고에서는 부산대학교병원 소아치과에서 국소적 치아 이형성증으로 진단받고, 2~5년간 정기적인 관찰을 받아온 5세 8개월~10세 9개월 어린이 3명을 대상으로 그 간의 치료 내용과 치아 발육과정을 검토해 보았다. 관찰 기간 동안 12개 이환치 중 심한 염증과 이형성으로 발거된 1개 치아를 제외한 모든 치아에서 석회화의 진행 또는 치조골 상방으로의 맹출성 이동을 보이긴 하였으나 그 정도와 속도는 개개 치아마다 매우 다양하였다. 그러므로 치료는 악골의 정상 발육과 공간 유지를 도모하고 치아의 조기 상실에 따른 부작용을 차단하기 위해서 이환치에 대하여 최대한으로 보존적인 접근을 하는 것이 추천된다. 또한 치아마다 그 발육정도가 다양하므로 개개 치아의 맹출 관리를 위한 독립적인 치료 계획을 수립하는 것이 바람직할 것으로 판단된다. Regional odontodysplasia is a relatively rare developmental anomaly of dental hard tissue with characteristic clinical. radiographic and histologic features. It requires a continuous and multidisciplinary approaches, and the aim of treatment for these patients should include aiding mastication. improving aesthetics. maintaining normal vertical dimension and space, allowing normal jaw growth and eruptional management of affected teeth. This report describes three cases of regional odontodysplasia with 2-5 years of follow-up. Conservative treatment is chosen to preserve the affected teeth as long as possible, and periodic radiographic and clinical examination was done. During this time, all teeth except one showed progressive development. An interesting finding observed in our cases was that each tooth even in the same person showed different degree of tooth development and eruption rate. Thus, we colcluded that the treatment plan for regional odontodysplasia should be conservative and individualized and based on the assessment of each tooth.
