이 연구는 전남 신안군 상태도에 위치한 상서고분군 축조에 사용된 석재들에 대한 암석학적 특성과 채석 등 유통과정에 대해 고찰하고자 하였다. 고분 축조에 사용된 석재들에 대한 암석학적 특성 연구는 외관적 관찰에 의한 암석기재적 연구와 편광현미경 하에서 암석의 광물조성과 조직특성에 대한 연구 및 암석의 주성분 함량조성을 통한 지구화학적 연구를 수행하였다. 이 연구들과 함께 주변지질들과 관련하여 고분석재들의 채석과 이송 등에 대한 연구도 병행하였다. 고대로부터 신안군 일대는 한국-중국-일본을 연결하는 고대 해상교통로에 중요한 위치를 점하는 것으로 알려져 고분 축조에 사용되었던 석재 연구는 고대 해양사 측면에서 의미를 지닌다고 할 수 있다. 기재적 관찰에서 석재들은 중성암맥 기원인 안산반암을 제외하고는 대부분이 응회암류에 해당한다. 이들은 라필리응회암과 세립질 응회암으로 구분되는데 대부분 세립질 응회암에 속한다. 응회암 구성입자들은 각상에서 초각상이고 분급도는 불량하다. 세립질 응회암들은 매우 치밀한 조직을 보유하고 특히 라필리응회암의 불규칙한 이탈흔들은 타포니(tafoni)와 관련될 가능성이 있다. 응회암의 입자들은 사장석편과 암편 등이 주를 이루며 크기 범위가 광범위하다. 사장석들은 알바이트 쌍정이 잘 나타나고 격자쌍정을 이루는 미사장석들도 출현한다. 응회암의 치밀한 조직은 부분적으로 속성작용과 관련되는 것으로 여겨지며 다양한 풍화정도를 보인다. 또한, 미세한 석영맥들이 응회암들을 종횡으로 관통하고 있다. 상기한 상서고분군 석재들에 대한 주성분 원소 함량에 대한 지구화학적 연구에 의하면, 이들 응회암은 화산암류 관점에서 산성암계열에 근접한 중성암 계열 및 산성암계열에 해당시킬 수 있다. 이러한 함량분포 특성 상, 이 응회암들은 두 가지 군으로 나눌 수 있다. 그리고 TAS(total alakali vs silica) 분류에서 이 응회암들은 저알칼리암 계열에 도시된다. 고분축조에 사용된 응회암들은 주변의 암석과 매우 유사하며 석재들 자체도 광물조상과 조직특성에서 서로 유사정도가 높다. 일반적으로 응회암들은 판상특성, 가공의 용이성 및 상대적인 견고성으로 고분과 건축 등에 많이 이용되어 왔다. 이러한 결과들을 기반으로 고분축조에 사용된 응회암들은 산성암계열에 근접한 중성암계열 및 산성암계열 기원을 가지며 주변 암석에서 채석·이송된 것으로 추정된다. This study considers on petrological characteristics and distribution to building stones of Sangseo tumuli in Santae Island, Shin-an, Jeonnam. The petrological study on the stones includes visually petrographical descriptions, textural study by polarized microscope and geochemical analysis. Along with the study, distribution routes of the stones were traced based on the regional geology of the island. Since ancient times, the study area is important as a base on international maritime traffic route. Therefore, studies on the tumuli are meaningful for ancient maritime history. In visual observation, above building stones are of tuffs except for an andesitic porphyry considered as intermediate dyke. The tuffs are assigned to lapilli and fine ones. Their grains are poorly sorted and angular to very angular in roundness. In particular, the fine tuffs show very dense textures and take up the most part of the building stones. In addition, the stones have irregularly removed depressions inferred as the linkage to tafoni, in lapilli tuffs particularly. The tuffs are mainly of plagioclases laths, rock fragments and matrices and ranges widely in grain size. The plagioclases show mostly unambiguous albite twin. And, microcline crystals are observed in the tuffs too. Matrices in the tuffs are considerably dense and weathered. Dense texture in the rocks are related to diagenesis in part. In addition, thin quartz veins irregularly intruded the rocks vertically and horizontally. According to the geochemical analysis of building stones of above tumuli, the stones might be intermediate rock series near acidic rock ones and acidic rock ones in the correspondence of volcanics. Therefore, the tuffs probably grouped as two types and are assigned to subalkaline rock series by TAS diagram. Most the building stones mutually resemble in visual and textural characteristics. Tuffs are generally platy, easy in use and relatively hard. In addition, rocks very similar to the building stones are widely distributed in surrounding area. Synthesizing above results, it is considered that tuffs used in tumuli building are corresponded to intermediate rock series near acidic rock ones and acidic rock, and got from surrounding rocks.

Hepatitis-B-associated glomerulonephritis is one of the immunologically mediated disorders associated with chronic Hepatitis B virus(HBV) infection. The frequency of HBsAg infection has been high in East Asia and it is one of the most important etiologic factors of the secondary glomerulonephritis. We reviewed the clinical and pathologic features of 29 patients with glomerulonephritis and HBs antigenemia, who were admitted to Chungnam National University Hospital from January 1988 to Febuary 1999. The results were as follows : 1) The average age of the patients was 33.8±10.4(mean±SD) and male to female ratio was 3.8. Proteinuria was present in 27 patients(93%), hematuria in 20 patients(69%) and hypertension in 17 patients(59%). Two patients(7%) manifested with renal insufficiency and 8 patients(28%) with nephrotic syndrome. 2) Renal pathology revealed membranous nephropathy(41%), membranoproliferative glomerulonephritis(21%), mesangial proliferative glomeulonephritis(21%), minimal change nephritis (14%) and focal segmental glomerulonephritis(3%). 3) The pathologic findings of liver were chronic active hepatitis(68%), chronic persistent hepatitis(38%) and liver cirrhosis(8%). 4) During the follow-up period(average:49.4 months), 7 patients(68%) presented persistent proteinuria, 5 patients(21%) progressed to renal failure and 2 patients(8%) resolved clinically. 5) The treatment was done with prednisolone to 3 patients, and with alpha-interferon to 3 patients. One patient treated with prednisolone resolved clinically, but this resolution did not coincide with disappearance of the hepatitis B antigens.

CAPD has established itself as an effective method maintaining the patients with end stage renal disease. CAPD peritonitis is one of the most important complication of peritoneal dialysis. We analyzed the incidence, pathogens, and outcome of the peritonitis, of the 95 patients who underwent CAPD at CNUH from January 1993 to July 1998. The result were as follows : 1) A total of 72 episodes of peritonitis occurred during this periods. The incidence of peritonitis were 0.64/patient/year. 2) The first episode of peritonitis was occurred within a year in 75%, within two year in 95.8%. 3) The rate of positive and negative culture were 27.8% and 72.2% respectively. Gram positive organisms were cultured in 60%, Gram negative organisms in 40%. S. aureus were most prevalent organisms(30%). 4) The cure rate were 83.3% in Gram positive organisms and 62.5% in negative organisms. 5) Peritoneal catheter were removed in 18 cases. Among them, 7 cases are due to peritonitis. In conclusion, improved technology and increasing patients' effort to careful management of catheter will reduce the incidence of peritonitis.

저자들은 만성알콜중독의 원인으로 음주자의 성격, 사회요인 등 여러가지 문제들이 게재되어 있지만 유전적 요인도 중요하리라고 생각되어 만성알콜중독자로 진단되어 국립부곡정신병원에 입원가료 중인 환자 30명을 대상으로 ADH2의 다형현상(polymorphism)을 조사하여 알콜중독자가 아닌 건강한 한국인의 유전자형과 비교한 결과 다음과 같은 결과를 얻었다. 만성알콜중독자 30명 중 ADH2-1/ADH2-1 형을 갖는 사람이 27명이었으며 ADH2-1/ADH2-2를 갖는 사람이 3명이었다. ADH2¹의 gene frequencies는 0.68이었으며 ADH²의 gene frequencies는 0.32로서 정상 한국인과 비교하여 유의한 차이가 없었다. This study was performed to know the gene polymorphism of alcoholic dehydrogenase(ADH)-2 in 30 Korean alcohol addicted patients who were admitted at Bugok National Mental Hospital. The results were as follows ADH2-1/ADH2-1 type among 30 alcohol addicts were 27 and ADH2-1/ADH2-2 type were 3. Gene frequencies of ADH2-1 were 0.68 and gene frequencies of ADH2-2 were 0.32 These results were not different from the gene polymorphism of ADH2 in non-alcoholic Korean healthy adults.

이강욱,신영태 충남대학교 의과대학 지역사회의학연구소 1993 충남의대잡지 Vol.20 No.2

Cicletanine HCl is the first delivative of the furopyridines, a new class of antihypertensive agents. The properties of cicletanin HCl involve increased prostacycline release, vascular H_1, H_3, receptor antagonism and modulation of intracytosolic free calcium. In order to evaluate the effect of cicletanine HC1 to renal function in hypertensive patients with renal disease, we examined twenty one patients with hypertension and renal disease in Chungnamnam National University Hospital, before and four weeks after administration of cicletanine HCl 100 mg per day . The results were as follows : 1. Mean age of patients was 50 years and man was 1.3 times more than woman. 2. Eight with hypertensive nephropathy, 7 with unknown cause chronic renal failure and 6 patients with diabetic nephropathy were included. 3. Systolic, diastolic and mean blood pressure of all patients decreased significantly, and 62 % of patients showed normalized blood pressure at end point of study 4. Parameters of renal function such as BUN, serum creatinine and creatinine clearence were not changed. 5. Amounts of 24 hour uninary protein excretion in patients goup with massive proteinuria ( >3.0 g/day,n = 13 ) decreased significantly, 4 weeks after cicletanine HCl administration. 6. Serum cholesterol, triglyceride, ALT, AST, uric acid, muscle enzyme and serum electrolytes shch as sodium, potassium, calcium and phosphorus remained unchanged. 7. There was no significant side effect during 4 weeks course of cicletanine HCI administration. With results above, we think that cicletanm HCl can be used safely in hypertensive patients with renal disease.

관상동맥질환에서 Tc-99m Methoxyisobutyl Isonitrile (MIBI) Myocardial SPECT의 이용 : Dipyridamole 심근부하 SPECT와 관상동맥조영술과의 비교 A Comparison between Coronary Angiography and Tc-99m-MIBI Myocardial SPECT

이강욱,전은석,박종훈,신영태,노흥규 충남대학교 의과대학 지역사회의학연구소 1993 충남의대잡지 Vol.20 No.2

In order to evaluate clinical utilities of Tc-99m MIBI dipyridamole stress myocardial SPECT in patients with coronary artery disease (CAD), we compaired tomographic and polar map images of Tc-99m MIBI myocardial SPECT with the results of coronary angiography in 25 patients with CAD (myocardial infarction 13,angina pectoris 12) in Chungnam National University Hospital from Oct. 1991 to Oct 1993. Percutaneous transcoronary angioplasty (PTCA) was done in three patients of 25 CAD patients and follow up SPECT studies were done in same three patients within 2 months after PTCA. The results were as follows : 1. Mean age of patients was 57.4 years. Man was 2.7 times more than woman. 2. Sensitivity and specificity of Tc-99m MIBI myocardial SPECT for the detection of coronary artery stenosis in patients with myocardial infarction were 92.7 % anf 85 %, respectively. 3. Sensitivity and specificity of Tc-99m MIBI myocardial SPECT for the detection of coronary artery stenosis in patients with angina pectoris were 100 % and 67 %, respectively. 4. After PTCA size of perfusion defects in stress SPELT images was decreased in all three patients . With the results above,we thought that Tc-99m MIBI myocardial SPECT is useful noninvasive method to detect stenosed coronary artery in patients with CAD and it can be used as a method to evaluate the result of PTCA.
