The double eyelid operation is one of the most common cosmetic surgery performed in orientals, and there are numerous studies about surgical procedures of that. In the case of appropriate candidates, the non-incision technique makes excellent cosmetic results, with the advantages of shorter operating time, less morbidity, less pain, no scarring and easy revision of shape. But, usually the non-incision technique is recommended in the cases with thin upper eyelid, small amount of orbital fat, less redundant skin of upper eyelid and in whom a wide fold is not desired so on. Therefore, the disadvantages of this method are that it cannot be applied to all patients. The postoperative complications are disappearance or faded fold, formation of cyst of lumps, asymmetry etc. and the incidence of these complications is slightly higher than those of the incisional method. In this study , the double eyelid operation using the continuous buried suture method was performed in 210 patients for formation of double eyelid from Jan. 1993 to Dec. 1995. In conclusion very good results can be obtained by the continuous buried suture method even in the cases of puffy upper eyelid. This method can make a double eyelid shape in the fashion the patient wants and can be a new indication for correction of unilateral double eyelid. This method is safe, satisfactory and take shorter postoperative recovery time and it can reduce the incidence of postoperative complications.

백락주,송기준,김상현,윤재경,김세연,송진원,이용주 대한감염학회 1997 감염 Vol.29 No.5

목 적 : 1991년 한탄바이러스 예방백신접종이 본격적으로 시행된 이후의 신증후출혈열 발생양상 및 한탄바이러스와 서울바이러스에 의한 감염비율에 대한 전반적인 역학조사와 새로운 한탄바이러스종의 존재 가능성을 증명하기 위하여 혈청학적 검사와 환자혈청에서의 한탄바이러스 항원검출을 시도하였다. 방 법 : 1994년 1월부터 1996년 12월까지 3년간 발생한 열성질환 환자중 신증후출혈열, 리케치아증 및 렙토스피라증 등이 의심되어 항체검사를 위해 고려대학교 의과대학 미생물학교실, 바이러스병 연구소에 의뢰된 혈청 8102건을 대상으로, 간접형광항체법, 혈구응집저지반응, 면역효소측정법 및 역전사 중합효소연쇄반응을 이용하여 한탄바이러스 감염에 대한 혈청역학적 연구 및 항원검색을 수행하였다. 결 과 : 간접형광항체법으로 조사한 한탄바이러스에 대한 항체 양성율은 30대 남자에서 가장 높았으며 10월에서 1월사이에 항체 양성 건수가 집중되어 있었다. 신증후출혈열 발생 빈도가 감소하고 있었으며 특히 건조기에 집중되었던 발생양상의 변화가 관찰되었다. 한탄바이러스에 의한 감염이 서울바이러스에 의한 감염보다 3배이상 높게 관찰되었으며 서울바이러스에 의한 감염은 고령층에서 더욱 빈발하였다. 한탄 및 서울 바이러스 이외의 새로운 한탄바이러스에 의한 감염 가능성이 확인되었다. 결 론 : 전반적으로 발생빈도가 감소하였으나 현재에도 우리 나라에서는 매년 수백명의 신증후출혈열 환자가 발생하며 한탄바이러스와 서울바이러스가 주요 원인체이나 새로운 한탄바이러스종의 존재 가능성이 확실하여 이의 규명을 위한 지속적인 연구가 수행되어야 할 것으로 사료된다. Background : Hantaan (HTN) and Seoul (SEO) viruses, harbored by the stripedfield mouse(Apodemus agrarius) and the Norway or common rat(Rattus rattus & Rattus norvegicus) respectively, were known to cause hemorrhagis fever with renal syndrome(HFRS) in Korea. We evaluated the seroepidemiologic patterns of hantaviral infection and detect the hantaviral antigens from patients sera. Methods : total 8,102 HFRS patients' sera were collected from 1994 to 1996, and examined by indirect immunofluorescent antibody technique(IFA), hemagglutination inhibition test(HI), IgM emzyme-linked immunosorbent assay(IgM-ELISA) and nested reverse transcription-polymerase chain reaction(RT-PCR). Results : The seropositive rate against hantaviral antigen was 12.0%(973/8102) with the high incidence rate(68.3%) in the period from October to January, and males in the thirties were mostly affected. HTN viral infections were detected 3.5 and 5.2 times higher than SEO viral infections by HI and RT-PCR, respectively, and patients in the fifties were the mostly affected age-group in SEO viral infections. IgM antibodies were detected in the 717 sera of the 905 IFA positive cases(79.2%), and the antigen detection rate of HTN and SEO viruses was 7.7%(56/724). Interestingly, 40 sera(4.4%), showed higher antibody titers against the puumala(PUU) virus than those against HTN or SEP viruses. Conclusion: The results showed HTN and SEO viruses were the main causative agents of HFRS in Korea, and also suggested the possible presence of PUU-related hantaviral infections.

백상철,박준봉 慶北大學校 齒科大學 1989 慶北齒大論文集 Vol.6 No.3

The purpose of this study was to observe the comparative clinical and histological changes associated with healing following the use of cyanoacrylates and no dressing in the 1st molar areas where gingivectomy procedures had been carried out. In this experimental study, 5 adult mongrel dogs were used and each dog divided into one control and the other experimental areas. The dogs were sacrificed on the 3rd, 7th, 14th, 21th, and 28th day. The experimental areas were observed clinically, and histological specimens were made following the usual methods and observes with light microscope. The results were as follows. In the clinical observations. immediately after the gingivectomy, postoperative hemostasis was made more rapidly on the experimental areas. On the 3rd day, the majority of the cyanoacrylate on the experimental areas were detached, and the complete detachment of the cyanoacrylate was observed on the 7th day. In the histologic observations, the experimental areas as compared with the controls:there was a thiner covering of fibrotic pseudoepithelium, and lesser edematous fibrous matrix and weaker inflammatory cell infiltration on the lower connective tissue was shown on the 3rd and 7th day. The extension of the blood vessels of the experimental areas was lesser than the control areas. But through the entire procedure of the histologic observations, there was little difference between two in the degree of healings after the 14day. On the 28th day, there was secondary inflammation on the both areas because of dental plaque and food debris.

양어용 사료첨가제로서 감귤발효액(EM-Fermented Orange)의 항산화특성

이준백,문상욱,이영돈,고유봉 제주대학교 해양연구소 2000 해양과환경연구소 연구논문집 Vol.24 No.-

Mandarine orange (Citrus unshiu Marc.) only added with sugar was fermented by effective microorganisms (EM) called "EM-fermented orange". EM was mainly composed of lactic acid bacteria, phototrophic bacteria and feast. As pH of EM-fermented orange reached 3.5 to 4.0 in the course of fermentation, the incubation was stopped. and then. EM-fermented orange was preservable at room temperature for about 6 months. Composition and concentration of free amino acids in EM-fermented orange were analyzed. Concentration of total amino acids was 167mg/l, and the relative content of carnosine (β-alanyl-L-histidine) which was well known as a kind of antioxidant materials was very high. 41%. In addition. crude extract showing antioxidant activity could be obtained from EM-fermented orange using some organic solvents. The antioxidant activity of the crude extract was equivalent to about 9% of that of vitamin E by the use of 1.1-diphenyl-2-picrylhydrazyl (DPPH) method. It was suggested that EM-fermented orange having antioxidant characteristics could promote the health of fish.

비골골절 환자에 대한 정복 후 만족도에 대한 임상적 연구

정성훈,박정일,최 준,백세민 大韓成形外科學會 1994 Archives of Plastic Surgery Vol.21 No.5

In the evaluation of the result of reduction of fractured nasal bone, 'the degree of satisfaction of the patient' is the most important factor. There were several reports regarding 'patient's satisfaction'. However they are not related to individual factors such as age, sex, cause of injury, method of reduction, etc but are the 'overall' rate of satisfied patients. We tried to know what should we do in the individual steps in treating fractured nose to reduce the rate of dissatisfaction. We analysed 120 consecutive patients who underwent reduction in Inje University Sanggye Paik Hospital due to fractured nose from August of 1989 to March of 1993. The results were as followings ; 1) There were many dissatisfied cases in second and third decades(p=0.054). 2) In case of severe combined injury requiring general anesthesia, the rate of dissatisfaction was high(p=0.061). 3) In cases with septal fracture, the rate of dissatisfaction was high(p=0.042). 4) The operation should be performed before 24 hours after trauma or on the fifth, sixth, and seventh posttraumatic day because the rate of dissatisfaction was low(p=0.023) 5) To evaluate the effect of splinting, further study is necessary. We should follow-up for longer time and it is difficult to define criteria of satisfaction of individual persons. We think that further research can clerify the protocol in the treatment of nasal bone fractures.

자일리톨과 불화나트륨을 함유한 저작성 정제가 교정환자의 구강위생에 미치는 영향에 관한 임상시험

유상훈,안석준,이신재,백승학,김태우,장영일,남동석 대한치과교정학회 2003 대한치과교정학회지 Vol.33 No.2

본 연구는 불화나트륨과 자일리톨 성분으로 구성된 구강 청정용 저작성 정제(덴포정, 하미즐, 부천, 경기)가 교정치료 중인 환자의 구강위생 상태에 미치는 영향을 알아보기 위해 시행되었다. 교정치료 중인 18세 이상의 성인 환자 30명을 대상으로 약제 상요 전, 2주 후, 4주 후에 피험자의 상악과 하악 전치 부위 및 구치 부위에서 각각 치은 지수, 치은 출혈 지수, 치태 지수를 측정하여 다음과 같은 결과를 얻었다. 1. 상하악 전치부와 구치부 모두에서 치태 지수가 약제 사용 전에 비해 사용 2주 후와 4주 후 유의성 있게 감소하였다(p<0.05). 또한, 적용 2주 후와 4주 후의 지수를 비교하였을 때 4주 후에 좀 더 개선된 경향을 보였으나, 통계적 유의성은 나타나지 않았다(p<0.05). 2. 치은 지수, 치은 출혈 지수도 상하악 전치부와 구치부 모두에서 적용 전에 비하여 2주 후와 4주 후 유의성 있게 감소하였다(p<0.05). 적용 2주 후와 4주 후의 지수의 비교 검증에서 통계학적으로 유의할 만한 차이가 보이지 않아 구강위생 상태의 개선이 계속 유지됨을 보였다. 본 연구의 결과는 치태 지수, 치은 지수, 치은 출혈 지수가 실험 정제 적용 후에 감소하여 구강위생 상태가 개선되었음을 보였다. 이러한 결과를 통해 덴포정을 교정치료 중인 환자에서 부가적으로 사용하였을 경우 치주조직의 건강을 증진시키는데 도움을 줄 수 있으리라고 생각된다. The aim of this study was to evaluate the effect a chewable tablet containing sodium fluoride and xylitol (DenPo, Hamizzle, Bucheon, Kyungki) on the oral hygiene state in the orthodontic patients. The subjects consisted of 30 adult orthodontic patients, who have worn the fixed orthodontic appliance at least 6 months. They were instructed to use the tablet forth a day. Gingival index (GI), plaque index (PI), and sulcus bleeding index (SBI) of upper and lower anterior and posterior regions were measured before using the tablet (TO), 2 weeks after using the tablet (T1), and 4 weeks after using the tablet (T2). The data were analyzed with Wilcoxon signed ranks tests. The results were as follows ; 1. PI was decreased significantly in the T1 and T2 stage compared with TO stage in the both anterior and posterior regions (p<0.05). Although PI was decreased in the T2 stage compared with T1, there was not statistical significance(p>0.05). 2. GI and SBI showed similar results compared with PL. In the T1 and T2 stage, there was statistically significant decrease in the GI and SBI (p<0.05). This study showed that the DenPo tablet could be used as an adjunct to improve oral hygiene in the orthodontic patients. The decrease of the indices may suggest that DenPo tablet could be effective in the plaque removal and prevention of gingival inflammation in the orthodontic patients.

To evaluate the in-vivo effects of mitomycin-C-polyglycolic acid composite(MMC-PGA) the disk: shaped composite were implanted into the peritoneal cavity of the Sprague-Dawley rats. The pathologic changes were examined at various time points up to 12 weeks. Initially the soft tissue around the inserted disks showed capillary congestion at 3 days. Inflammatory infiltrates with foreign body giant cells appeared from the 2nd week and reached peak response at 6-8 weeks. These reaction diminished prominently at 12 weeks. No specific pathologic change was found in the liver, the kidneys, and the heart. The above results suggest that the MMC-PGA composite can serve as a new device for intraperitoneal chemotherapy of various types of cancers.

Locally recurrent rectal cancer is a difficult clinical problem. Local recurrence following treatment for rectal cancer is a major cause of morbidity and mortality. The reported range of local recurrence rates following surgical treatment for rectal cancer has varied from 4% to 50%. We retrospectively reviewed the charts of 142 rectal cancer patients from January 1991 to December 1999. Analysis of patients factors included age, gender, type of surgery, and adjuvant therapy. Tumors were assessed for level, stage, and grade. Local recurrence and distant metastases were also documented. Variables influencing local recurrence in this group were identified and disease-free survival is determined. Of the 142 patients(74 males, 68 females; mean age 62.6 years), 137 consecutive patients operated on for rectal cancer and followed up to December 2000 (range 23-118months) were analyzed. Local recurrence rate was 18.3%. Age and sex of patients, type of surgery, location of tumor in the rectum, size, morphology and grading of the tumor were all unrelated to the event under investigation. At Cox regression, the Dukes stage and the postoperative radiotherapy were the only independent prognostic factors for local recurrence, and Dukes stage (Hazard ratio=2.89, p<0.001) and local recurrence (Hazard ratio=3.31, p<0.01) were the only independent factors associated with improved survival.
