임현주,황종현,류재근,정병천,조용근,채성철,전재은,박의현 慶北大學校 醫科大學 1997 慶北醫大誌 Vol.38 No.1

목적 : 관상동맥질환의 위험인자로서 혈청지질 및 혈장 지단백에 대한 관심이 높아지고 있고 또 아포지단백이 관상동맥 질환을 일으키는데 다른 지질보다 더 중요하다는 연구가 많이 발표되고 있으나 우리나라에서는 아포지단백에 대한 연구가 그리 많지 않은 편이다. 이에 저자등은 혈중지질치와 새로운 위험인자로 알려지고 있는 아포지단백치를 측정하고 이들과 관상동맥질환 중증도와의 상관 관계를 알아보았다. 대상 및 방법 : 관상동맥질환이 의심되어 관상동맥조영술을 실시한 69명의 환자를 대상으로 하였으며 12시간 이상 공복후 혈청을 채취하여 총콜레스테롤, 중성지방, HDL-콜레스테롤, 아포지단백 AI (ape AI), 아포지단백 B (ape B)를 측정하였다. 관상동맥조영상 50%이상의 협착이 있는 혈관의 수 (lesion number), 최대협착을 합한 값 (lesion score), 각 분절의 최대협착을 합한 값 (total score), 가장 심한 협착 값 (peak stenosis) 등으로 관상동맥 중증도를 알아본 다음 이들과 혈청지질치, 아포지단백과의 상관 관계를 비교해 보았다. 상관 관계는 Spearman's correlation coefficient를 구하였다. 결과 : 관상동맥질환의 중증도와 각 지질치 간의 상관 관계를 비교해 보았을때 lesion number와 관계있는 것은 연령 (r=0.2789), 중성지방치 (r=0.2829)이며 lesion score와 관계있는 것은 연령(r=0.2911), 중성지방치0 (r=0.3316), 총콜레스테롤과 HDL-콜레스테롤의 비 (r=0.2361), apo B 치(r=0.2759), apo AI과 apo B의 비 (-0.3154)로 나타났다. Total score는 연령 (r=0.3100), 총콜레스테롤치 (r=0.2452), 중성지방치 (r=0.3022), 총콜레스테롤과 HDL-콜레스테롤의 비 (r=0.2770), apo B치 (r=0.2927), apo AI과 apo B의 비 (r=-0.3408)와 연관이 있었고 peak stenosis는 중성지방 치(r=0.3305), ape B 치 (r=0.2968), apo AI과 apo B의 비 (r=-0.3977)와 관계가 있었다. 연령으로 조정하여 partial correlation을 좌면, 관상동맥조영술상 중증도는 중성지방치 (r=0.3408), apo B 치(r=0.2877), apo AI과 apo B의 비 (r=-0.3460)와 유의한 상관 관계가 있었다. 이중 ape AI과 ape B의 비는 lesion score (r=-0.2640), total score (r=-0.3057), peak stenosis (r=-0.3460)와 유의한 상관관계를 보였다. 결론 : 이상의 결과로 보아 apo B치 그리고 apo AI과 apo B의 비가 관상동맥 중증도의 예견인자로 다른 혈중 지질 치보다 더 유용하다는 것을 알 수 있었다. Objectives : Recently, it was reported that the measurements of apolipoprotein levels may be valuable in the clinical assessment of coronary artery disease severity. However there are a few reports regarding to the relationship between coronary artery disease severity and apolipoprotein levels in Korea. Thus, we measured serum lipid and apolipoprotein levels and studied the relationship between coronary artery disease severity and serum lipids and apolipoproteins levels. Subjects and Methods : The 69 patients who underwent coronary angiography to evaluate chest pain were subjected to this study. We measured the levels of serum cholesterol, triglycerides, HDL cholesterol, apolipoprotein AI(apo AI) and apolipoprotein B(Apo B) and measured the severity of coronary artery disease by lesion number, lesion score, total score and peak stenosis. Then, we studied the relationship between coronary artery disease severity and apolipoproteins and calculated the correlation coefficient. Results : The results were as follows. There are significant correlation(r=0.3) between age, triglycerides, apo B levels, apo AI/B ratio and coronary artery disease severity. In controlling for age, tyiglycerides, apo B levels and apo AI/B ratio shows significant correlation(r=0.3) with coronary artery disease severity. Especially, apo AI/B ratio shows significant correlation(r=0.3) with lesion number, total score and peak stenosis. Conclusion : These results suggest that the apo B levels and the ratio of apo AI/B can be used as significant independent predictor for coronary artery disease severity rather than other serum lipid levels.

The relative density seems to be important as a factor of controlling the physical properties in the case of cohesionless soil ground as sand. Therefore, the study is more important about the method for reappearing he same relative density when the specimen of shearing test is to be produce or the model test of ground is to made. In this study, the apparatus making use of the multiple sieving pluviation method-one of the reappearance of relative density-could be made. Using this apparatus, tests were practiced varying the factors such as the size of sieve mesh and the number of sieve, the amount of falling discharge, the falling height etc. about the standard sand in Jumunjin and Hadong sand. When laboratory test is perfomed by the cohesionless soil, it presents the method for reappearing of the relative density in field.

The purpose of this study was to evaluate the bacterial adherence on e-PTFE membrane immersed in whole saliva from subjects with different periodontal status. Experiment involved 3 subjects groups : 5 persons with healthy periodontium(probing depth below 3mm and no signs of gingival inflammation including bleeding on probing), 10 patients with gingivitis(probing depth below 3mm and apparent signs of gingival inflammation), and 10 patients with advanced periodontitis(probing depth over 7mm and apparent signs of gingival inflammation). Each disease group was included before and after scaling and root planing treatment. After obtaining whole saliva from each subject, e-PTFE membrane(Gore-Tex periodontal membrane : GTPM??, W.L. Gore & Associates, Flagstaff, USA) specimens were immersed at room temperature in the saliva aliqouts for 1, 3, 7 days. The weight between pre-and post-immersion in saliva was measured with the analytical balance and the difference was recorded. The specimens were processed for SEM observation. The bacterial adherence on the membrane specimens was evaluated using the scanning electron microscope images. The obtained results were as follows : 1. There was no difference in the weight of bacteria adherent to e-PTFE membrane specimens according to the periodontal status and the immersion periods. 2. As the exposure time to saliva increased, the bacterial adherence to the membrane specimen significantly increased in all groups(P<0.005). 3. As the severity of periodontal disease increased, the bacterial adherence to the membrane specimens significantly increased(P<0.001). 4. After scaling and root planing, the bacterial adherence to the membrane specimens significantly decreased in gingivitis and periodontitis patient group(P<0.001). These results suggest that bacterial contamination on exposed barrier membrane surface be reduced through improvement of periodontal status and oral health environment before and after GTR procedure for the successful outcome.

Background and Objectives : Hemorrhage is one of the most common complication after tonsillectomy. Despite of many various efforts, it still remains unsolved problem to many otolaryngologist. Because so many factors are related to postoperative bleeding after tonsillectomy, so we tried to see the postoperative hemorrhage rate in relation to various parameters. Material and Methods : A retrospective study on patients who had underwent tonsillectomy in Wallace Memorial Baptist Hospital for 6 years from January 2002 to December 2007. Parameters such as sex, seasons of year, age distribution, tonsil size, previous tonsillitis history and anesthesia type were considered. Results : Overall hemorrhage rate was 2.6%. Postoperative hemorrhage was common in adult males with incidence of 4.5% and most of them was secondary hemorrhage. In age distribution, the incidence was high in the group of 16~30 year. Bleeding was common in autumn, grade II tonsil and increased when the history of tonsillitis was frequent, and local tonsillectomy was better in terms of bleeding compared with tonsillectomy under general anesthesia. but there was no statistical significance. Conclusion : To reduce the incidence of postoperative hemorrhage, perioperative education and complete bleeding control during operation is important for high risk patients.

In this study, the relation of discharge patterns with the radiated electromagnetic waves is investigated by measuring electromagnetic waves using a antenna and a spectrum analyzer. The patterns of radiated electromagnetic waves measured at the atmospheric pressure in Liquid Nitrogen(LN_(2)) during the partial discharges in nonuniform electric field depend on positive DC power. From these points of view, it is considered that these results obtained from this investigation may be used as fundamental data for diagnosis and prediction of insulation on the equipments of superconducting and cryogenic applications.

The follow-up studies on the outcome of pregnancy and infant having amniocentesis during midpregnancy were analized. Only 483 pregnant women gave the informations for the follow-up study among 1453 patients having amniocentesis during midpregnancy from Jan. 1976 to Dec. 1978 at the department of Obstetrics and Gynecology, Kyung Hee University Hospital. The results were as follows: 1. The 483 pregnant women having amniocentesis gave fullterm delivery in 457 (94.62%), premature delivery in 8 (1.86%), immature delivery in 2 (0.41%) missed abortion in 1 (0.21%), induced abortion in 3 (0.41%) and on pregnancy in 10 (2.07%). 2. Of 473 births, 4 still births, 9 neonatal deaths and 4 infant deaths were encountered. 3. Artificial inductions of the pregnancy were carried out in 3 cases such as a 47 XYY syndrome of the fetus, an anencephalus and a patients who had vaginal leakage of amniotic fluid after amniocentesis. 4. A total of 29 patients complained as follows: Abdominal pain in 15, amniotic leakage in 5, vaginal spotting in 4, amniotic fluid leakage with abdominal pain in 4 and vaginal spotting combined with vaginal leakage in 1. 5. The risks involved in amniocentesis for prenatal diagnosis are in our experience small, so that even the use of relative indication for sampling is justified. However, even if there are no increased statistical risk, there should be carried out by experienced obstetricians. 6. Of 278 term deliveries, 63 (22.66%) cases had permanent contraceptions such as tubal ligations or vasectomies and 100 (35.9%) cases are on temporary contraceptives after delivery.
