Enamel Microabrasion을 시행한 법랑질과 복합레진의 전단결합강도

홍기상,이상훈,이상대 大韓小兒齒科學會 2000 大韓小兒齒科學會誌 Vol.27 No.1

Enamel microabrasion은 염산과 연마제를 사용하여 치아의 착색을 제거하는 술식으로서, 그 효과는 법랑질 표층에 국한된다. Enamel microabrasion으로 모든 착색이 치료 가능한 것은 아니므로, 착색이 깊을 경우에는 microabrasion후에도 제거되지 않고 남은 착색부위를 광중합 복합레진을 사용해 수복할 것이 권장된다. 본 연구의 목적은 enamel microabrasion의 방법과 시간이 법랑질에 대한 복합레진의 전단결합걍도에 미치는 영향을 조사하는 것이었다. 아무런 처치도 하지 않은 대조군을 1군으로 하였고, 18% 염산과 fine pumice의 혼합물을 hand applicator로 치면에 5초씩 5,10회 적용시킨 것을 각각 2,3군으로 하였다. 10% 염산과 연마제의 혼합물인 기성품 PREMA를 10:1 gear reduction handpiece로 20초씩 5, 10회 적용시킨 것을 각각 4,5군으로 하였다. 여기에 37% 인산으로 부식 후 복합레진을 결합시켜 thermocycling 후 전단결합강도를 측정하여 다음과 같은 결론을 얻었다. 1. 2군이 가장 높은 결합강도(24.36±3.34MPa)를 나타내었고, 3군이 가장 낮은 결합강도 (19.35±3.43MPa)를 보였다. 전단결합강도는 2>4>5>1>3군의 순서로 감소하였다. 2. 2군은 1군과 3군보다 통계학적으로 유의성있게 높은 결합강도를 나타내었다(p<0.05). 3. 염산과 pumice로 enamel microabrasion을 시행한 2,3군과 PREMA를 사용한 4,5군 사이에는 유의한 결합강도의 차이가 없었다 (p<0.05) 4. 파절면 검사에서, adhesive failure는 3,4군에서 나타났고, cohesive failure는 1,2,3,4군에서 관찰되었다. 5군에서는 mixed failure만이 관찰되었다. 5. SEM관찰에서, 염산과 pumice로 enamel microabrasion을 시행한 2,3군에서는 인산으로 부식한 것과 비슷한 표면양상이 관찰되었고, PREMA로 처리한 4,5군에서는 1군과 흡사한 매끈한 표면양상이 관찰되었다. 각 군의 시편을 인산으로 부식시킨 다음에는 전형적인 산부식 후의 표면양상이 관찰되었고, 군간 별다른 차이가 없었다. Enamel microabrasion is a means by which superficial enamel discoloration is removed using hydrochloric acid and fine pumice. As enamel microabrasion alone may not by sufficient in cases of deeper discoloration, composite resin restoration is recommended in areas where there is remaining discoloration. The purpose of this study was to investigate the effects of different methods and number of applications of enamel microabrasion on the shear bond strength of composite resin to enamel. Untreated control was designated as groups1,5-second applications of a mixture of 18% HCI and fine pumice were performed 5 and 10 times on groups 2 and 3, respectively. A commercially available mixture of 10% HCI and abrasives (PREMA) was appliedusing a 10:1 gear reduction handpiece 5 and 10 times on groups 4 and 5, respectively, with each application lasting 20 seconds. After etching with 37% phosphoric acid, composite resin was bonded. Thermocycling was performed and shear bond strength was measured. The following results were obtained: 1. Group 2 showed the highest bond strength(24.36±3.34), while group 3 showed the lowest (19.35±3.43). Shear bond strength decreased in the following order: 2>4>5>1>3. 2. Group 2 showed bond strength significantly higher compared to groups 1 and 3(p<0.05). 3. There were no significant differences between groups 2 and 3, which had been microabraded using HCI and pumice, and groups 4 and 5, to which PREMA had been applied, when bond strengths were compared(p>0.05) 4. When modes of fracture were examined, adhesive failure was observed in groups 3 and 4, while cohesive failure was observed in groups 1,2,3 and 4. Only mixed failures were found in group 5. 5. When viewed using a SEM, groups 2 and 3, which had been microabraded using HCI and pumice, showed surface appearances similar to that of enamel etched with phosphoric acid. Groups 4 and 5, treated with PREMA, exhibited a smooth surface similar to that of group 1. All groups showed similar, typical surface characteristics following phosphoric acid etching.

The condition of operation and maintenance for selected small water systems in An Sung was surveyed. Eight small water systems were selected among one hundred ninety systems in An Sung. The environment, especially contaminant source around the systems was reevaluated. Questionnaire was also conducted to find out the recognition of inhabitants and/or managers for the operational difficulty and management problems of the systems. Twenty percent of the respondents was not satisfied with the flow rates of the supplied water and 16% with the water quality. Eighty percent of the respondents wanted to enhance the existing treatment facilities by installing additional filtration and/or disinfection process. Only 13% of the managers of the small systems were regularly paid. The limit of their role and responsibility seemed unclear and the development of practical and responsible management program for small water systems is expected.

Objective In order to study the effects of bee venom(BV) on the pain, edema, and acute inflammatory reactant of rheumatoid arthritis(RA) patients. Methods Patients with RA who met the ACR(American College of Rheumatology) 1987 revised criteria for the diagnosis of RA were treated with the BV therapy twice a week for 3 months. Tender Joint counts, swollen joint counts, Visual analog scale(VAS), morning stiffness, ESR. C-reactive protein(CRP) were analyzed before and after BV therapy. Results The results as follows. 1. Tender joint counts in patients after BV therapy were significantly lower than those before BV therapy(9.0±7.9 vs 15± 11.4, p=0.002). 2. Swollen joint counts of the patients after BV therapy were significantly lower than those before BV therapy(50±61 vs 15±23, p=0.001). 3. VAS in patients after BV therapy was significantly lower than those before BV therapy(608± 17.6 vs 380± 159, p=0.000). 4. Duration of morning stiffness in patients after BV therapy was significantly reduced compared with that before BV therapy(119.1± 112.6 min vs 59.0±89.7 min, p=0.009). 5. ESR and CRP were not significantly changed before and after BV therapy, suggesting BV itself could make inflammatory reaction as well as therapeutic effect. Conclusions BV therapy improved tender joint counts, swollen joint counts and duration of morning stiffness in this study, and further study is needed on long-term effect of BV therapy.

Korean Dictionaries and Some Model Dictionaries of the World : Critical Essays toward the Plan for a New Korean Dictionary

Lee, Sang Sup,Nam, Ki Shim,Ahn, Sam Huan,Choi, Young Ai,Hong, Chai Song 연세대학교 언어정보개발원 1988 사전편찬학 연구 Vol.1 No.1

After briefly reviewing the history of lexcoigraphy in modem Korea, Nam Kishim tackles many problems created by the general deficiency of current Korean monolingual dictionaries in phonological morphological and semantic points. For example, most Korean dictionaries do not treat such phonological changes as the shortening of the stem vowel ㅓ in 더운, the prenominal form of the adjective 덥다, whose stem vowel ㅓ is pronounced long. He also takes issue with the practice of Korean dictionaries of including all kinds of proper names on little reliable principles : a typical dictionary enters a 600m-high hill while excluding better-known mountains higher than that. Hong Chai-song concentrates on the often misguiding information on transitive / intransitive verbs in current dictionaries. For example, a representative dictionary designates the verb 뛰다 simply as intransitive. But it is quite often used as an transitive also. In the sentence, 철수는 운동장을 뛰었다, 운동장 is the object of the transitive verb 뛰다. How could the compilers miss such an obvious fact? Hong suggests that they may have not been interested in being grammatically informative. A historical survey of the Oxford English Dictionary(OED) is given by Lee Sang-sup, with special emphasis on the vast amount of quotations from real sources contributed by thousands of volunteer readers through several decades and on its unwavering historical principle. A comparison between the OED's definition of Kimchi and a Korean dictionary's 김치 is given, showing the difference of principle in treating the same lexical item. Ahn Sam-huan presents a detailed account of Grimm's Deutsches Wo¨rterbuch which took generations of German lexicographers 133 years from its inception to its completion in 1971. On the basis of his study, Ahn suggests that future dictionary makers should cooperate as a group on a long-range comprehensive project. A moltivolume dictionary is an all-important cultural event for the whole nation, not to be influenced by private commercial interests. Choi Young-ai's survey of Chinese lexicography highlights the now on-going publication of 漢語字典 and 漢語詞典, admirable results of the cooperative effort of hundreds of Chinese scholars, a modus operandi for the Yonsei University graze to adopt in planning a new dictionary of the Korean language.

Background Lack of universal replication system for hepatitis B virus with narrow host range and organ tropism has hampered to uncover the pathogenesis of HBV. Previously, we reported the essentiality of humoral milieu and its components toward HBV and hepatitis C virus survival/viability in vitro. Of these components, the precise role of enterohepatic humoral milieu such as bile acid (BA) on HBV cultivation in vitro and in vivo is unknown. Objective We explored whether BA, specifically taurochenodeoxycholic acid (tCDCA) would directly regulate the viral DNA and surface antigen expression of HBV in vitro, consequently rendering HBV to enter into human or murine immortalized hepatocytes, and non-hepatocytes. Result We found that higher concentration of taurochenodeoxycholic acid (tCDCA) is able to preserve the genomic stability of HBV in cell-free DMEM, showing higher the surface antigenicity than taurocholic acid (tCA). In line, we found that in vitro cell culture condition (100 μmol/L of tCDCA coupled with 1 × 108 g e/mL HBV) would be optimal for HBV entry into target cells. Using this, human (HepG2, Huh7), and rodent (Hepa1c1c7, H4-II-E) hepatoma cell lines were infected by HBV, as evidenced by the presence of HBV biomarkers (HBsAg, and HBV DNA in culture supernatant, as well as HBcAg in cell). Further, cellular entry test revealed that HBV is able to infect 12 different non-hepatic cell lines regardless of species, and organ/tissue, consequently reproducing progeny as confirmed by HBV biomarkers. Last, reinfection test showed that the progenies of HBV from immortalized HepG2, and Hepa1c1c7 cells are able to enter into each or vice versa naïve HepG2, and Hepa1c1c7 cells with or without BA. Conclusion This study demonstrates that enterohepatic humoral milieu such as BA, specifically tCDCA would directly regulate HBV DNA and its surface antigen expression in vitro, consequently rendering HBV to enter into human or murine immortalized hepatocytes, and non-hepatocytes. This is the first note to render HBV permissive to human or rodent hepatic and non-hepatic cells via sole manipulation of humoral milieu, thus establishing the platform for in vitro robust replication system of HBV.
