수부는 전체 체표면적의 2%를 차지하는 적은 면적이지만 그 기능면에서는 대단히 중요한 역할을 하며 화상에 의한 수부의 피부 손실은 대개의 경우 전신 화상의 일부로서 나타나기 때문에 화상 초기 전신상태에 치중하다보면 흔히 소홀히 다루어지게 되어 수부기형을 초래하는 수가 많다. 따라서 수부에 화상을 받으면 초기부터 기능면을 고려하여 치료에 임하여야 한다. 저자는 1974년 1월부터 1978년 12월까지 만 5년간 이화여자대학교 의과대학 부속병원에 입원 가료를 받았던 수부 화상 환자 81예에 대한 임상적 연구 결과 다음과 같은 결론을 얻었다. 1) 성별 발생빈도는 남자 56명, 여자 25명으로 청장년군의 사회활동과 관계가 있어 남자에서 높았다. 2) 연령별 발생빈도는 수부화상 81예 중 4세 이하가 28명으로 가정에 일어난 우발사고였는데 이는 보호자의 소홀한 보호와 부주의였다. 3) 수부화상 81예 중 수부에만 국한된 화상은 8예로서 전신화상의 일부로서 수부화상이 주로 나타남을 보여주었다. 4) 수부화상시 조기 관절운동을 시행하여 관절 강직을 예방하여야 하며 운동이 불가능할 때에는 functional postion으로 수부를 유지시켜야 하고 심한 2도 내지 3도 수부화상시는 조기 소가 절제와 피부이식을 시행하여 기형을 최소로 줄이는 좋은 결과를 얻을 수 있다. In general, the functional limitation of the burned hand is determined by the thermal injury ; however, infection, pressure necrosis, inactivity, poor postioning, subsequent scarring and contractures are intimately related to functional disability. The goal of treatment of the burned hand is the prevention of deformitites and maintenance of function. We have undertaken an analysis of our clinical experiences on the burned hand and a review of the literature. During the last five years, from january 1974 to December 1978, 81 cases of burned hand have been treated at the surgical department of Ewha Womans University Hospital.

Background: The aim of this study was to determine whether the conventional subcostal approach is suitable for emergency pericardiocentesis in patients with cardiac tamponade or impending cardiac tamponade. Methods: This study was a prospective, observational study conducted at the emergency department of a tertiary hospital, Patients who had symptomatic pericardial effusion and who needed emergency pericardiocentesis in the emergency department were included in this study. We measured the epicardium-to-pericardium distance at the subcostal, parasternal, and apical area with two-dimensional echocardiography to determine the appropriate puncture site for pericardiocentesis. An epicardium-to-pericardium distance of more than 1.0 cm was considered as the primary safety factor in determining the Puncture site for pericardiocentesis. The skin-to-pericardium distance was considered as secondary safety factor. Results: Ninety-five consecutive patients(55 males and 40 females; total mean age: 53 year old) with cardiac tamponade or impending cardiac tamponade were enrolled in this study. The puncture site for pericardiocentesis, as determined by echocardiography, was the subcostal area in 43 patients(45%), the apical area in 40 patients(42%), the left parasternal area In 11 patients(12%), and the right parastemal area in one patient(1%). Pericardiocentesis failed in 2 patients(2%) with the subcostal approach and in one patient(1%) with the apical approach. The average epicardium-to-pericardium distance was 31 ±21 mm in patients with the subcostal approach and 21±8 mm in patients with other approaches. There were no differences in the amount of pericardial fluid and in the intraperical pressure among patient groups according to puncture site. There were two procedure related complications: a puncture of the right ventricle with the subcostal approach and a ventricular tachycardia with the apical approach.

김두상,김영신,고재경,한중수 한양대학교 의과대학 1992 한양의대 학술지 Vol.12 No.1

In order to find out a possible role of acid deoxyribonuclease (DNase) in carcinogenesis of the ovary, activity of the enzyme was measured and the nature of the enzyme was studied in serous cystadenocarcinoma and endodermal sinus tumor of the ovary following the purification of the acid DNase in the tumor tissue of the ovary. (1)The acid DNase activity was greatly increased in the tumor tissues of the ovary, serous cystadenocarcinoma and endodermal sinus tumor tissues, while neutral and alkaline DNase activities were unchanged in the tumor tissues. This may indicate that the acid DNase can be used as a biochemical marker for the ovary tumors. (2)Proteins in the tumor tissues of the ovary were separated by a DEAE-cellulose column chromatography into 7 peak, respectively, of which one peak protein each appeared to be specific for serous cystadenocarcinoma and endodermal sinus tumor. (3)Acid DNases in the tumor tissues of the ovary were isolated into a single peak, respectively. The size of peak in the tumor tissues was greater than that in the control tissue of the ovary, indicating that the acid DNases in the tumor tissues were activated, but not specific for the tumors. (4)Acid DNases in the tumor tissues of the ovary were partially purified by centrifugation and a DEAE-cellulose column chromatography. The purified enzyme was highly active against double stranded DNA (ds-DNA), even though some activity was found against single stranded DNA (ss DNA). Observations that acid DNase from serous cystadenocarcinoma tissue was highly active and specific to ds DNA compared with ss DNA suggested that the enzyme might play a role in transforming normal ovarian cells into cancer cells.

The tool geometry parameters and cutting process have complex relationships. Until now, various cutting test were needed to acquire optimal design of end mill for the purpose of high speed machining, due to the insufficient knowledge about cutting process in high speed machining. Using various tools with different geometry, relationships between tool geometry parameter (rake angle, clearance angle, length of cutter) and cutting process (cutting force, surface accuracy, surface roughness) have been studied. Acquired data can be used to design optimal tool for high speed machining and developed tool geometry design S/W.

액취증 치료의 궁극목적은 겨드랑이에서 나는 독특하고 심한 냄새를 제거하는 데 있다. 액취증의 제어에는 피부표면과 털로부터 apocrine sweat의 외관적 광범위 절제뿐이다. 저자는 1978년 3월부터 1980년 2월까지 만 2년간 이화여자대학교 의과대학 부속병원 성형외과에서 입원수술을 받았던 액취증 환자 31예에 대한 임상적 연구 결과 다음과 같은 결론을 얻었다. 1) 액와부위의 피부와 선조직의 광범위 절제술을 시행한 31예 중 독특한 악취가 재발된 예가 없었던 것으로 보아 광범위 절제술이 액추증 치료에 만족한 방법임을 나타내었다. 2) 광범위 절제술과 동시에 Z-성형술을 시행하면 선상반흔 구축으로 인한 견부의 외전 운동 장애를 예방할 수 있다. Bromhidrosis, or osmidrosis, is a condition in which an excessive odor, usually offensive, emanates from the skin, The axilla is really the only site from which the distinctive apoctine odor derives. Thirty-one patients have had a total exicision of all the axillary sweat glands, with closure incorporating a Z-plasty. The result of this method has been found to be more reliable than other methods. Brief review of literature is added.

각종 치과레이저의 Streptococcus mutans에 대한 증식 기능억제 효과

한강석,국중기,유소영,김화숙,박종휘,박현동,이상훈 大韓小兒齒科學會 2003 大韓小兒齒科學會誌 Vol.30 No.3

레이저의 구강내 산 생성 세균인 S. mutans에 대한 증식 및 기능 억제효과를 평가하기 위하여 S. mutans KCTC 3065가 포함된 세균 pellet에 Er:YAG 레이저와 Nd:YAG 레이저를 비접촉식 방법으로, 조사세기 50mJ, 조사시간 5초, 그리고 pulse repetition rate를 각각 10Hz와 30Hz로 하여 조사하고 세균 군락수, 산 생성능, 불용성 세포외다당류의 합성량을 측정하여 다음과 같은 결과를 얻었다. 1. Chinese ink로 photosensitization을 시행한 후 Nd:YAG 레이저를 조사한 경우가 S. mutans의 증식을 가장 많이 억제하였으며 Er:YAG 레이저 조사도 증식을 억제하였다. Chinese ink를 사용하지 않고 ND:YAG 레이저를 단독으로 조사한 경우는 S. mutans의 증식을 억제하지 못하였다. 2. Chinese ink로 photosensitization을 시행한 후 Nd:YAG 레이저를 조사한 경우가 일정기간 동안 S. mutans의 산생성능을 가장 많이 억제하였으며 Er:YAG 레이저 조사도 산 생성능을 억제하였다. Chinese ink를 사용하지 않고 Nd:YAG 레이저를 단독으로 조사한 경우는 S. mutans의 산 생성능을 억제하지 못하였다. Er:YAG 레이저와 Chinese ink로 photosensitization을 시행한 후 Nd:YAG 레이저를 조사한 경우는 pulse repetition rate가 클수록 전반적으로 세균의 산생성능을 더 많이 억제하였다. 3. 레이저 조사는 S. mutans의 불용성 세포외다당류의 합성에 영향을 미치지 못하였다. 이상의 결과로 보아 Er:YAG 레이저와 Chinese ink로 photosensitization을 시행한 후의 Nd:YAG 레이저 조사는 일정시간 동안 S. mutans의 증식과 산 생성능을 억제시키므로써 치아우식증 예방효과를 얻을 수 있다고 사료되나 억제효과가 오래가지 않아 임상적으로 효과를 얻기 위해서는 자주 조사를 해주어야 한다는 문제점을 안고 있어 임상적으로 치아우식증 예방이란 단독 목적으로 사용하기에는 실용성이 크지 않다고 사료된다. This was performed to evaluate the inhibitory effect of laser on the growth of S. mutans. The bacterial pallets containing S. mutans KCTC 3065 were irradiated with Er:YAG laser and Nd:YAG laser by non-contact method at an intensity of 50mJ for 5 sec with the pulse repetition rates of 10Hz and 30Hz, respectively. The following results were obtained on colony count, acid producing ability, and the amount of insoluble extracellular polysaccharide synthesis. 1. The irradiation of Nd:YAG laser after photosensitization with Chinese ink inhibited the proliferation of S. mutans the most, and the irradiation of Er:YAG also inhibited the proliferation. However, the irradiation of Nd:YAG laser alone could not inhibited the proliferation of S. mutans. The pulse repetition rate did not affect significantly on the proliferation of bacteria in overall. 2. The irradiation of Nd:YAG laser after the photosensitization with Chinese ink inhibited the acid production of S. mutans the most for a certain period of time. Er:YAG laser also inhibited acid production. When Nd:YAG laser was used alone, the acid production of S. mutans was not been inhibited. The irradiation of Nd:YAG laser after photosensitization with Chinese ink inhibited the acid production ability of bacteria the most as the pulse repetition rate increased. 3. Laser irradiation did not inhibited the synthesis of insoluble extracellular polysaccharide of S. mutans. From these results, we conclude that the irradiatioin of Er:YAG laser and Nd:YAG laser after photosensitization with Chinese ink would inhibit the proliferation and acid production by S. mutans, which may prenent dental caries. However, this effect does not last long time so that the laser irradiation should be repeated frequently in order to obtain clinical effect; thus, this laser irradiation would not have a clinical usefulness in preventing dental caries when used solely.
