Objectives : There are a number of preceding epidemiological studies reporting gender differences in the genetic etiology of alcohol dependence. The author investigated gender difference in the frequencies of ADH2 and ALDH2 genoypes between the patients with alcohol dependence and normal control. Methods : The subjects were 141 alcohol dependent patients (104 males, 37 females) and 138 normal control (79 males, 59 females). The frequencies of 1/1 and 1/2+2/2 (2+ afterward) genotypes for ADH2 and ALDH2 were investigated in male and female between alcohol dependence and normal control group. DNA was extracted from WBC in peripheral venous blood and PCR-RFLP method was used out for genotyping. Results : First, the frequency of ADH2 1/1 genotype was significantly higher in alcohol dependent patients than normal control in both genders. Second, while there was no gender difference in the frequency of ADH2 1/1 genotype in normal controls, in the patient group however, the frequency was significantly higher in females than males. Third, in male subjects with alcohol dependence, the frequency of ALDH2 1/1 genotype was significantly higher than in male normal control subjects. On the other hand, in female subjects with alcohol dependence, the frequency of ALDH2 2+ genotype was significantly higher than in female normal control subjects. Conclusion : These results suggest that while the risk of alcohol dependence is predominantly affected by ALDH2 1/1 geno-type in male, the female ADH2 1/1 genotype is mainly associated with the risk of alcohol dependence. This means that there are gender differences in the genetic etiology of alcohol dependence.

가다랑어 혈합육을 보다 효율적으로 이용하기 위한 일련의 기초연구로서, 가다랑어 혈합육의 지질성분, 함질소엑스분 및 구성아미노산 등을 보통 육과 함께 분석하여 비교, 검토하였다. 보통육은 혈합육에 비해 수분, 조단백질 함량은 약간 많은 반면, 조지방과 회분 함량은 혈합육이 약간 많았다. 휘발성염기질소량은 보토육이 22.7mg/100g, 혈합육이 46.9mg/100ㅎ으로 혈합육이 보통육에 비해 선도저하가 훨씬 빨랐다. 보통육과 혈합육의 총지질 조성은 각각 중성지질 79.7%, 71.9%, 당지질, 6.8%, 9.5%, 인지질13.5%, 18.6%로 이루어져 있었다. 중성지질의 성분은 free fatty acid ac triglyceride, 인지질은 phosphatidyl ethanolamine, phosphatidyl, 인지질은 phosphatidyl choline이 주성분이었고, lysogud 인지질의축적도 확인되었다. 총지지르 중성, 당 및 인지질의 축적도 확인되었다. 종지질, 중성, 당 및 인지질의 지반산 조성에서 보통육은 16:0 및 18:1을 주체로 한 포화산 및 모노엔산의 조성비가 혈합육보다 높았으며, 혈합육은 폴리엔산, 특히 22:6의 비율이 월등히 높았다. 16:0. 18:0, 18:1, 20:5 및 22:6 등이 주요 구성지방산이었다. 유리아미노산의 조성은 총함량에서 보통육 쪽이 많았고, 보통육에는 histidine, 혈합육에는 tauring의 보통육에서는 680.9mg.100g 정도 전존해 있었으나, 혈합육에서는 IMP의 분해가 급속히 진행되어 73.1mg/100g에 지나지 않았다. TMAO 및 TMA는 보통육에 비해 혈합육에 휠씬 많이 함유되어 있었고, total creatinine은 보통육 쪽이 많았다. 구성아미노산의 조성은 양시료 간에 별차이가 없었고, glutamic acid, aspartic acid, lysine, leucine, alanine, isoleucine 및 arginine 등이 주요 구성아니노산이었다. The lipid components, nitrogenous extracts and amino acids of dark muscle(DM) of skipjack (Katsuwonus pelamis) were analyzed and compared with those of white muscle(WM). WM was higher in moisture and crude protein content, and lower in crude lipid and ash content than those of DM. Contents of volatile basic nitrogen in WM and DM were 22.7mg/100g and 46.9mg/100g. Total lipid(TL) of WM and DM consisted of 79.7%, 71.9% neutral lipid(NL), 6.8%, 9.5% glycolipid(GL), and 13.5%, 18.6% phospholipid(PL), respectively. NL was mainly composed of free fatty acid, triglyceride, and PL was mainly occupied by phosphatidyl ethanolamine, phosphatidyl choline. Also lysophosphatidyl choline and lysophosphatidyl ethanolamine were identified in PL. In fatty acid composition of TL, NL, GL and PL, WM revealed higher contents in saturates and monoenes such as 16 : 0, 18 : 1, while DM showed higher contents in polyenes such as 22 : 6 especially. The major fatty acids of these samples were generally 16 : 0, 18 : 0, 18 : 1, 20 : 5 and 22 : 6. Contents of total free amino acids from WM and DM were 5,982.3mg/100g and 4,450.7mg/100g (dry base). Of free amino acids, Tau concentration was much higher in DM than in WM, Ala, Gly, Met, Arg, Thr were also high in DM. But His was much higher in concentration in WM. Content of inosinic acid(IMP) in WM(680.9mg/100g) was higher than that of DM(73.1mg/100g). The degradations of IMP proceeded very rapidly in DM. DM contained much higher trimethylamine oxide and trimethylamine than those of WM. The profile of combined amino acids in these samples were very similar, and main amino acids were Glu, Asp, Lys, Ala, Ile and Arg.

Objective: The authors investigated the frequency of persecutors in persecutory delusions of the psychiatric patients who didn't undergo the arrest or traumatic injury, reside in Gwangju Jeonnam area, and were admitted to the hospital after the 5.18 prodemocracy movement in Gwangju in 1980 upward 10 years. Also this study investigated the frequency of the persecutors before and after the prodemocracy movement and in capital and Gwangju Jeonnam area. Subjects and Methods: Among the 896 patients who were admitted to department of psychiatry, Chosun University Hospital from Jan. 1. 1989 to Dec. 31. 1991, we choosed 144 patients with persecutory delusion who had lived in Gwangju Jeonnam area for 10 years after 5.18 prodemocracy movement as subjects. Persecutors were classified into 7 class: unspecified, family, neighbors, communist or spy, police or army or secret agent, impersonal, others. Results: 1) In our study, the frequency of persecutors was family, unspecified, neighbors, police or army or secret agent, impersonal, others, communist or spy in descending order. As compared to previous studies (1956-2003) including our study about frequency of persecutor at capital area and Gwangju Jeonnam area, and before and after 5.18 prodemocracy movement, 2) At capital area, in the early 1980s, police, family, neighbors, unspecified person was frequent in descending order. In the both of early 1970s, 1990s, neighbors, family, unspecified person, police was frequent in descending order. 3) At Gwangju Jeonnam area, in the early 1970s, family, unspecified person, neighbors, police was frequent in descending order. In the early 1990s, unspecified person and family, neighbors, police was frequent in descending order. 4) The police class was most frequent at capital area in the early 1980s. Conclusions: We suppose that class of persecutor in persecutory delusions of psychiatric patients are changing according to social change, and frequency of police class was decreasing in both of capital and Gwangju, Jeonnam area.

김국찬,이강석,김진규,김인규,박효국,천기정,김상복 대한방사선 방어학회 1993 방사선방어학회지 Vol.18 No.2

우라늄 피폭후 효소활성도가 내부피폭의 biomarker로서의 가능성을 연구하기 위하여 수서생물인 잉어9Caprinus carpio)의 복강내 우라늄 투여시 간조직에서 일어나는 여러가지 효소계의 변화를 조사하였다. 이러한 효소활성도의 변화는 우라늄 내부피폭의 biomarker로서 가능성을 가지고 있으며 연구결과는 다음과 같다. 1) 6일째까지 우라늄을 주사하여 적출한 간에서의 전체단백질량은 계속 감소하고 있다. 2) 세포내의 lysosome내에 함유하고 있는 acid protease와 β-glucuronidase의 활성도는 6일째 투여후까지 활성도가 감소하고 있다. 3) Alkaline phosphatase의 경우 6일째 우라늄 투여후까지 증가하고 있으며 반대로 acid phosphatase의 경우 6일째 우라늄 투여후까지 활성도가 급격히 증가하였고 glutamate oxaloacetate transaminase의 활성도는 완만하게 증가하고 있다. 4) Creatine kinase의 활성도는 완만한 감소를 보이고 있으며 malate dehydrogenase는 첫번 우라늄 투여후에 활성도가 급격히 감소하였고 3일째 우라늄 투여후에는 활성도가 거의 나타나지 않았다. We examined various enzyme activity changes by intraperitioneal injection uranium in the carp liver. These enzyme activity changes can be used as biochemical indicators of internal exposure to uranium. The results were followings ; 1) Total protein concentration decreased by intraperitoneal injection in the carp liver. 2) Lysosomal acid protease and β-glucronidase activities increased in the liver until sixth intraperitoneal injection of uranium, but lysosomal acid phosphatase activities decreased in the liver until the sixth injection of uranium. 3) Alkaline phosphatase activities sharply increased and Glutamate oxaloacetate Transaminase activities steadily decreased in the liver until the sixth injection of uranium. 4) Creatine %kinase activities steadily decreased and malate dehydrogenase activities sharply decreased in the liver after the primary injection of uranium. Any malate dehydrogenase activities was not detected after sixth injection of uranium.

김진규,김상복,김국찬,천기정,김인규,박효국,이강석 대한방사선 방어학회 1993 방사선방어학회지 Vol.18 No.2

생물학적 선량평가를 위한 생화학적 지표 연구로서 흰쥐 혈액내 효소활성도의 변화를 조사한 결과는 다음과 같다. 1) Alkaline phosphatase 활성도는 0.1, 0.25, 0.5, 2, 4 Gy의 방사선 조사후 24시간까지 혈액내 활성도가 증가하였고 72시간 경과시에는 대조군과 비슷한 활성도를 보였다. Creatine kinase는 2, 4 Gy 방사선 조사후 혈액내에서 활성도에서 활성도가 72시간까지 증가하였으나 0.1, 0.25Gy, 0.5 Gy 방사선 조사시에는 커다란 변화를 보이지 않았다. 2) Malate dehydrogenase 활성도는 0.1, 0.25, 0.5 Gy 방사선 조사시에는 커다란 변화가 없었으며 lactate dehydrogenase는 방사선 조사후 활성도가 감소하였다. 3) GOT의 활성도는 선량률 0.1Gy/min.로 0.1, 0.25, 0.5, 2, 4 Gy 조사후에는 어떠한 변화도 없었으며 선량률 0.5 Gy/sec.로 0.5, 1, 1.5, 2, 3, 5, 7 Gy로 조사후에는 증가현상을 보이고 있다. Acid phosphatase 활성도는 상기의 어떠한 선량에서도 나타나지 않고 있다. 잠재적으로 이러한 효소들은 방사선 피폭의 지표물질로 사용될 수 있으며 생화학적 지식과 기술을 이용한 좀더 나은 지표물질을 찾기 위하여 계속적인 조사가 필요하다. Enzyme activity changes in rat blood as biochemical indicator useful for evaluating exposure dose were experimentally studied. The experimental results obtained are as follows: 1) Alkaline phosphatase activities increased in the blood serum until 24 hours after 0.1, 0.25, 0.5, 2 and 4 Gy irradiation and its activities returned mormal condition after 72 hours of post-irradiation. Creatine kinase activities increased in the blood serum until 72 hours after 2 and 4 Gy irradiation but any significant activity changes were not detected after 0.1, 0.25 Gy irradiation. 2) Malate dehydrogenase activities did not reveal available changes changes after 0.1, 0.25, 0.5 Gy irradiation and lactate dehydrogenase activities decreased in the blood serum after 0.1, 0.25, 0.5 Gy irradiation. 3) Glutamate oxaloacetate transaminase activity changes were detected in the blood serum after 0.1, 0.25, 0.5, 2, 4 Gy(0.1 Gy/min.) and GOT activities increased after 0.5, 1, 1.5, 2, 3, 5, 7 Gy(0.5 Gy/sec.). Any acid phosphatase activities were detected in the blood serum after 0.1, 0.25, 0.5, 2, 4 Gy(0.1 Gy/min.) and 0.5, 1, 1.5, 2, 3, 5, 7 Gy(0.5 Gy/sec.) irradiation. Potentially some of these enzymes can be used as indicator protein for radiation injury. Futher investigation is needed to find better biochemical indicatiors utilizing recent knowledge and techniques of biochemistry.

관상동맥 약물 방출 스텐트 삽입 후 스텐트 골절에 대한 임상결과 및 예후

김인수(In Soo Kim),한재복(Jae Bok Han),장성주(Seong Joo Jang) 대한방사선과학회(구 대한방사선기술학회) 2014 방사선기술과학 Vol.37 No.2

본 연구에서는 관상동맥 중재술로 관상동맥 약물방출 스텐트(drug-eluting stent, DES) 삽입 후 스텐트 골절에 대한 임상적 특성, 결과 및 예후에 대하여 연구하였다. 약물방출 스텐트 시술을 받고 추적 관상동맥조영술을 실시한 4,701명 환자에서 스텐트 골절이 발생한 환자는 32명(남:여=19:13, 평균연령 62.44±9.8세, 0.68%)이었다. DES의 종류별 스텐트 골절의 빈도는 SES(sirolimus- eluting stents) 19(59.4%), PES(paclitaxel-eluting stents) 9명(28.1%), BES(biolimus A9-eluting stents) 2명(6.3%), EES(everolimus-eluting stents) 1명(3.1%), EPC(endothelial progenitor cell capture stent) 1명(3.1%), ZES(zotarolimus-eluting stents) 0명(0%) 이었다. 표적 병변은 우관상동맥 13명(40.6%) 좌전하행지 16명(50.0%), 좌회선지 3명(9.4%)이었다. 각 혈관의 병변 형태는 복잡병변인 B2, C형이 25명(69.4%)이었다. 스텐트 골절 환자 중 스텐트 내 협착은 17명(53.1%)이었으며, 스텐트 골절 병변에 대한 치료는 내과적 관찰 16명(50.0%), 동종의 관상동맥 DES 시술 3명(9.4%), 이종의 관상동맥 DES 시술 10명(31.3%), 관상동맥 풍선 확장술 3명(9.4%)이었다. 추적검사에서는 32.9±12.4개월 동안 스텐트 골절로 인한 사망을 포함한 심장사는 발생하지 않았다. 결론적으로 관상동맥 중재술로 관상동맥 DES를 시술받은 추적관찰 대상 환자에서 3.7년 추적관찰 기간동안 스텐트 골절 발생률은 0.68%로 나타났으며, PES보다 SES에서 많은 발생 빈도를 보였다. 좌전하행지와 복잡병변에 대한 시술 후 스텐트 골절이 많이 발생하였다. 또한 스텐트 골절 정도와 협착 병변이 중대한 경우에만 관상동맥 중재술을 실시하였으며, 추적관찰 기간 중 스텐트 골절이 있는 환자는 병용 항혈소판 요법을 지속적으로 투여하였다. 특히 사망을 포함한 주요 심장사건에 관련하여 스텐트 골절과 연관된 심장사의 발생률은 매우 낮은 것으로 나타났다. 본 연구를 통해서 스텐트가 가지고 있는 특성 스텐트 디자인이 폐쇄형(closed cell) 디자인 SES에서 발생 빈도가 높음을 제시함으로써 스텐트 개발에 도움이 될 거라 판단된다. Many studies have suggested that in the era of Drug-Eluting Stents(DES) are one of the causes of In-Stent Restenosis(ISR) of Stent Fracture(SF). The present study sought to evaluate clinical characteristics of patients with stent fracture after successful DES implantation. The 4,701 patients were selected for analysis who underwent a follow-up coronary angiography irre-spective of ischemic symptoms. The overall incidence of SF was 32 patients(male:female=19:13, Av. age 62.44±9.8year, 0.68%). Fractures of Sirolimus-Eluting Stents(SES), Paclitaxel-Eluting Stents(PES), Biolimus A9-Eluting Stents(BES), Everolimus-Eluting Etents(EES), Endothelial Progenitor Cell Capture Stent(EPC) and Zotarolimus-Eluting Stents(ZES) are accounted for 19(59.4%), 9(28.1%),2(6.3%),1(3.1%),1(3.1%)and 0(0%) respectively. SF developed in the left Anterior Dscending(LAD) artery in 16 patients(50%) and in complex(type B2, C) lesions in 25 patients(69.4%). Ten patients were treated with heterogenous DES, the rest being treated with either homogenous DES(3 patients), plain old balloon angioplasty(3 patients), or conservative medical treatment(17 patients). None of the patients with SF suffered from cardiac death dur-ing a follow-up period of 32.9±12.4 months. The overall rate of DES fracture over up to 3.7 years of follow-up was 0.68% with higher incidence in SES than in PES. SF frequently occurred in the LAD artery and in complex lesions. Of the patients with SF, coronary intervention was performed only when the binary restenosis lesion was significant. During the follow-up, patients with SF have continued on combination antiplatelet therapy. There is a very low rate of major adverse cardiac events(post-detection of SF), especially cardiac death associated with SF.

김인수(In-Soo Kim),정명호(Myoung-Ho Jeong),한재복(Jae-Bok Han),장영일(Young Ill Jang),장성주(Seong-Joo Jang) 한국콘텐츠학회 2013 한국콘텐츠학회논문지 Vol.13 No.12

약물방출 스텐트 (drug-eluting stents, DES)는 일반금속 스텐트에 비하여 재협착을 현저하게 줄었지만, DES의 구조적인 특성으로 인한 스텐트 혈전증 (stent thrombosis, ST)이 증가한다고 알려져 있다. 혈전증 유형의 정의는 Early ST ; (EST)은 30일 이내, Late ST ; (LST)은 31일 이상에서 1년 이내 그리고 Very late ST ; (VLST)은 1년 이상으로 분류 하였다. 스텐트 세대별 (시장 출시와 스텐트 디자인, Polymer 향상에 따른) ST발생빈도, 임상 양상 및 예후를 알아보았다. 2003년 6월부터 2013년 6월까지의 전남대학교병원 심혈관센터에서 경피적 관상동맥 중재술을 시행 받은 10,273명 중 ST 발생은 134명(1.30%) 이었다. 세대별 발생빈도는 1세대에서 81명 (0.79%)으로 높았으며, 세대별 ST 유형은 1세대에서는 VLST의 발생률이 높았고 (p=0.002), 2세대에서는 EST와 LST의 발생률이 높았지만 (p=0.025), 3세대에서는 유의한 차이가 없었다(p=0.278). ST로 인하여 사망한 14명은 EST 10명 (18.2%), LST 2명(8.3%), VLST 2명 (3.6%)로서 EST에서 사망률이 높았다 (p=0.042). DES 시술 후 발생하는 ST는 1.3%이였고, VLST는 1세대 스텐트에서 많았으며, 입원 중 사망률은 EST에서 높았다. Stent thrombosis after successful drug-eluting stent(DES) implantation has been reported in around 1% of patients in clinical trials. However, the increased risk of ST associated with DES remains a matter of concern. From 1 June 2003 to 30 June 2013, we investigated clinical characteristics, in-hospital outcomes in 10,273 patients who underwent percutaneous coronary intervention in the Heart Center of CNUH. Overall incidence of ST was 1.30% (134 patients). The incidence of ST according to the stent generations and the timing of ST (n= total, early vs. late vs. very late) were 0.79% (n =81, 26 vs. 12 vs. 43) in first-generation, 0.38% (n=39, 21 vs. 9 vs. 9) in second-generation and 0.14% (n=14, 8 vs 3 vs. 3) in third-generation, (p=0.70). The mortality from ST was significantly higher in early ST group compared to the late and very late ST groups (18.2% vs. 8.3% vs. 3.6%, p=0.042). Overall incidence of ST after DES implantation was 1.30% (134 patients). The in-hospital mortality was significantly higher in early ST group compared to the late and very late ST groups.

약물용출 스텐트를 이용한 관상동맥중재술 후 재협착의 독립적 예측인자에 관한 연구

김인수(In-Soo Kim)한재복(Jae-Bok Han),장성주(Seong-Joo Jang),장영일(Young-Ill Jang) 대한방사선과학회(구 대한방사선기술학회) 2010 방사선기술과학 Vol.33 No.1

본 연구에서는 약물용출성 스텐트 삽입 후 재협착에 관한 독립적 인자를 확인하고 MDCT로 측정된 calcium score가 재협착 발생의 예측인자로써 가능성을 알아보고자 하였다. 2006년 5월부터 2009년 5월까지 전남대학교병원에서 MDCT상 관상동맥 협착이 발견되어 약물 용출 스텐트를 삽입 받은 환자 1,131명 중 추적검사로 관상동맥조영술을 시행되었던 178명(남자 159명, 여자 19명, 평균 연령 61.7, 연령분포 51~71세), 190개소 병변을 대상으로 하였으며 재협착 여부에 따라 두 군(비협착군 133병변, 재협착군 57병변)으로 나누어 비교 ․ 분석하였다. 그 결과 임상진단명은 진구성 심근경색이 비협착군 3예(2.3%), 재협착군 5예(8.8%)로 유의한 차이가 있었으며(p = 0.040), 급성 심근경색증, 불안정 협심증, 안정 협심증의 유병률은 차이가 없었다. 관상동맥 조영술 소견에서 병변 혈관의 위치는 재협착군에서 좌주간지 병변이 더 많았다(0.8% vs. 5.3%, p = 0.047). 스텐트 직경은 재협착군에서 유의하게 작았으며(3.3±0.4 mm vs. 3.1±0.3 mm, p = 0.004), 스텐트 길이는 양군 간에 차이가 없었다. 관상동맥 조영술 상 혈관의 초기 협착 정도는 재협착군에서 더 심했으며(86.1±11.4% vs. 91.5±9.2%, p = 0.001), 복잡 병변(B2/C형)은 양 군간에 차이가 없었다. 연령은 재협착군에서 더 높았고(60.2±9.9세 vs. 65.8±9.0세, p = 0.0001), 흡연력과 고지혈증은 비협착군에서(42.1% vs. 19.3%, p = 0.003, 23.3% vs. 8.8%, p = 0.019), 그리고 당뇨병은 재협착군에서 많았다(21.8% vs. 52.6%, p = 0.0001). 심초음파로 측정한 좌심실 구혈률은 양 군 간에 유의한 차이는 없었다. 전체 MDCT coronary artery calcium scoring는 비협착군 371.2±500.8, 재협착군 389.3±458.3로 차이가 없었고, 목표혈관과 좌주간지, 좌전하행지, 좌회선지 및 우관상동맥 각각의 calcium score 역시 양군 간 차이가 없었다. 다 변량 로지스틱 회귀분석에서 좌주간지병변(OR = 168.0, 95% CI = 7.83-3,604.3, p = 0.001), 남성(OR = 36.5, 95% CI = 5.89-2,226.9, p = 0.0001), 당뇨병의 존재(OR = 2.62, 95% CI = 1.071~6.450, p = 0.035)가 약물용출성 스텐트 삽입 후 재협착 발생에 대한 독립적인 예측인자이었다. 따라서 관상동맥 협착에 대해 약물용출 스텐트를 삽입 받은 환자에서 스텐트 내 재협착의 발생은 좌주간지병변, 남성, 당뇨병의 존재와 관련이 있었으나, MDCT로 측정된 calcium score는 재협착 발생에 대한 독립적인 예측인자로써 기능은 없었다. We sought to confirm an independent factor about in-stent restenosis (ISR) in the patients who underwent drug-eluting stent (DES) and know a possibility as a predictor of measured coronary artery calcium score by MDCT. A total of 178 patients (159 men, 61.7±10.0 years of age) with 190 coronary artery lesions were included in this study out of 1,131 patients who underwent percutaneous coronary intervention (PCI) with DES implantation for significant stenosis on MDCT at Chonnam National University Hospital between May 2006 and May 2009. All lesions were divided into two groups with the presence of ISR : group I (re ISR, N = 57) and group II (no ISR, N = 133). Compared to group II, group I was more likely to be older (65.8±9.0 vs. 60.2±9.9 years, p = 0.0001), diabetic (21.8% vs. 52.6%, p = 0.0001), have old myocardial infarction (8.8% vs. 2.3%, p = 0.040), left main stem disease (5.3% vs. 0.8%, p = 0.047), and smaller stent size (3.1±0.3 mm vs. 3.3±0.4 mm, p = 0.004). Group II was more likely to be smokers (19.3% vs. 42.1%, p = 0.003), have dyslipidemia (8.8% vs. 23.3%, p = 0.019). Left ventricular ejection fraction, lesion complexity, and stent length were not different between the two groups. Total CAC score was 389.3±458.3 in group I and 371.2±500.8 in group II (p = 0.185). No statistical difference was observed between the groups in CAC score in the culprit vessel, left main stem, left anterior descending artery, left circumflex artery, and right coronary artery. On multivariate logistic regression analysis, left main stem disease (OR = 168.0, 95% CI = 7.83-3,604.3, p = 0.001), male sex (OR = 36.5, 95% CI = 5.89-2,226.9, p = 0.0001), and the presence of diabetes (OR = 2.62, 95% CI = 1.071-6.450, p = 0.035) were independent predictors of ISR after DES implantation. In patients who underwent DES implantation for significant coronary stenosis on MDCT, ISR was associated with left main stem disease, male sex, and the presence of diabetes. However, CAC score by MDCT was not a predictor of ISR in this study population.

1976年부터 1979年까지 慶北 漆谷카톨릭皮膚科病院에 來院한 外來患者中에서 臨床的 및 眞菌學的으로 頭部白癬으로 確診된 154例에 對하여 觀察한 成積을 다음과 같이 要約한다. 頭部白癬은 總外來患者의 0.19%에 該當하며 1976年부터 1978年까지는 큰 變動이 없었으나 1979年에 갑자기 2~3倍로 增加되었다. 男女의 罹患比는 7歲未滿에서는 큰 差異가 없으나 8~14歲群에서는 男子가, 高年齡群에서는 女子가 높았다. 그러므로 1961年以前에 比하여 男女間에 큰 差異가 없어지고 있다. 總分離菌 136株中 M. canis가 97株(71.3%), T. ferrugineum이 26株(19.1%), T. mentagrophytes가 10株(7.4%), T. rubrum이 3株(2.2%)이었다. 이 成績이 1961年前에 比하여 T. ferrugineum은 1977年부터 顯著히 減少되는 反面에 M. canis가 急增되어 主要菌의 交替現象이 일어나고 있다. T. ferrugineum은 14歲未滿의 男子에 많고 M. canis는 男女 모두 14歲未滿에서 많았으나 特히 女子에서는 7歲未滿과 高年齡群에 많았다. 特히 M. canis感梁이 7歲未滿 兒童에 많았으므로 앞으로 感染源인 고양이의 索出과 이에 對한 適切한 加療가 必要하다. Reports have been made of the detailed clinical and mycological observation on tinea capitis in the Taegu area during the period of 1954 through 1961. There had been, however, no follow-up studies on the disease until 1975. With the reports on the increasing incidence of Microsporum canis infections throughout the country, we suppose that the clinical features and the causative agents of tinea capitis may differ from those observed between 1954 and 1961. The authors observed 154 cases of tinea capitis at Chilgok Skin Clinic during the period from 1976 to 1979, clinically and mycologically. Tinea capitis occupied 0.19% of total outpatients in the clinic, and the incidence increased markedly during 1979. There was no general difference in incidence rates between both sexes of children, but a tendency was noted male children were predominant among the age group of 8 to 14, while female children were predominant among the age groups of under 7 and over 40 years. Among 136 fungi isolated from patients M. canis was most frequently found with 97 (71.3%) strains, and followed by 26(19.1%) of Trichophyton ferrugineum, 10(7.4%) of T. metagrophytes and 3(2.2%) of T. rubrum. These results indicate that T. ferrugineum which was the most predominant agent of tinea capitis before 1962, is decreasing markedly, while M. canis is increasing rapidly as the causative agent. The number of strains isolated in 1979 was more than the total number of strains in 1976 through 1978, showing that the predominance of causative agents in tinea capitis is changing toward M. canis, as compared with the distribution of agents before 1962. T. ferrugineum was frequently isolated from male children under the age of fourteen. M. canis was predominant in both sexes under the age of fourteen, but was predominant among patients under the age of seven and a higher age group in female.

Depression is associated with a dysfunctional serotonin (5-hydroxytryptamine; 5-HT) system. More recently, several lines of evidence suggest that an important factor in the development of depression may be a deficit in the function and expression of $5-HT_{1A}$ receptors. The present study assessed if Nelumbinis Semen (N. s.) had an anti-depression effect through reversing a decrease in $5-HT_{1A}$receptor binding in rats with depression-like symptoms induced by chronic mild stress. Using a $5-HT_{1A}$ receptor binding assay, with a specific $5-HT_{1A}$receptor agonist, 8- OH-DPAT (8-hydroxy-2-(di-n-propylamino) tetralin), the mechanism of the anti-depression effect of N. s. on rats was investigated, and the effects compared with two well-known antidepressants, Hyperium Perforatum (St. Johns Wort) and fluoxetine (Prozac). Animals were divided into five groups: the normal (N) group without chronic mild stress (CMS), the control (C) group under CMS for 8 weeks, the Nelumbinis Semen (N. s.) treatment group under CMS for 8 weeks, the Hyperium Perforatum (H. p.) treatment group under CMS for 8 weeks and finally, the fluoxetine (F) treatment group under CMS for 8 weeks. Each treatment was administered to rats during the last 4 weeks of the 8-week CMS. A sucrose intake test was performed to test the anti-depression effect of N. s. The N. s. treatment significantly reversed the decreased sucrose intake under CMS (P<0.05 compared to control group under CMS). In the CA2 and CA3 regions of the hippocampus, both N. s. and H. p. reversed the CMS-induced decrease in $5-HT_{1A}$receptor binding. In the I to II regions of the frontal cortex, N. s. and H. p. also reversed the CMS-induced decrease in$5-HT_{1A}$receptor binding, and even showed a significant increase in $5-HT_{1A}$receptor binding compared to the F treatment group (N. s. vs. P, p<0.05, H. p. vs. P, p<0.05). However, in the hypothalamus, all treatments reversed the CMSinduced decrease in $5-HT_{1A}$receptor binding. This reversal effect of N. s. on the decrease in $5-HT_{1A}$receptor binding in the frontal cortex, hippocampus and hypothalamus of rat brains was very similar to that of H. p, but different from that of F. It is concluded that N. s. presents an anti-depression effect through enhancing $5-HT_{1A}$receptor binding.
