          저자등은 1980년 1월부터 1984년 6월까지 경북대학병원 신경외과에 입원된 뇌지주막하 출혈 환자중 출혈의 원인이 밝혀지지 않았던 52명의 환자를 대상으로 하여 임상적으로 분석, 관찰하였다. 원인 미상의 뇌지주막하 출혈은 충분한 검사가 시도된 환자중 22%에서 나타났다. 남, 녀의 발생비는 1.4대 1이었으며 연령층별로는 51-60세층에서 32.7%로써 가장 높은 빈도를 나타내었으며 다음이 41-50세층으로써 26.9%였다. 입원당시 신경학적 장애정도는 경도가 55.8%로써 가장 많았으며 중등도와 심도가 각각 28.8% 및 15.4%이었다. 재출혈의 빈도는 11.5%이었으며 대개가 3개월이내에 있었다. 출혈에 의한 두개내 합병증은 23.1%에서 있었으며 주로 출혈에 의한 뇌실의 확장과 혈관연측에 의한 것이었다. 입원, 치료기간은 대개 3주 미만이었으며 퇴원시 치료의 결과는 신경학적 장애가 경할수록 좋았다. 생존자는 96.2%이었으며 Good상태로의 호전은 82.7%였다. 그리고 사망률은 3.8%로 분석되었다. The authors made clinical analyses and observations on 52 patients with SAH whose causes had been unknown, admitted to Department of neurosurgery, Kyungpook National University Hospital from January 1980 through June 1984. The 52 cases accounted for 22 percent of the whole patient with SAH who has been subjected to a variety of thorough diagnostic procedures. The ratio of incidence of male to female was 1.4 to 1. Ages, 51-60, occupied 32.7 percent mostly frequent; 41-50, 26.9 percent, second highest in frequency. The breakdown in degree of neurologic disorders showed; mild-55.8 percent, moderate-28.8 percent and severe-15.4 percent. The frequency of rebleeding was 1.5 percent, most of which occured within 3 months following the first attack. Intracranial camplications due to bleeding, mostly ventricular dilatation, vasospasm, were found among 23.1 percent of the cases. The admission period was mostly 3 weeks or less. 96.2 percent of the studied cases survived and the mortality was 3.8percent. And 82.7 percent of the whole cases was recovered in good conditions.

        • 천막상부의 대형 뇌동·정맥기형 : Clinical Observation on Large Supratentorial Arteriovenous Malformations

          成周慶,咸印碩,朴淵默,金乘來 慶北大學校 醫科大學 1984 慶北醫大誌 Vol.25 No.2

          천막상부 대뇌에서 발생된 대형 뇌동, 정맥기형 환자 25명을 대상으로 하여 분석 관찰하였다. 남녀의 발생비는 5.4대 1이었다. 연령별 분포는 21세에서 40세까지가 전체의 60%였으며 평균 연령은 31세였다. 우측 대뇌반구에서의 발생은 60%였으면 두정엽과 전두엽에서의 발생은 각각 40%로써 가장 높은 빈도였다. 신경학적 증상과 소견은 두통이 76%로서 가장 많았으며 출혈 소견, 의식장애, 대측에 운동 및 지각 장애, 간질, 시야결손 및 잡음의 청취 순이었다. 출혈은 68%에서 있었으며 첫 출혈의 년령은 21∼30세 및 31∼40세층에서 각각 39.4%로서 가장 많았다. 40세 미만에서의 출혈은 88.2%이었다. 수술군은 52%이었으며 사망자는 없었다. 수술군에서 술후 결과는 술전에 비해 호전된 것이 69.2%었으며 변함이 없거나 악화된 것이 각각 15.4%이었다. Clinical analyses were made on 25 patients with supratentorial large arteriovenous malformations. The ratio of male to female was 5.4 to 1 in incidence. The age group, 21-40, in male took up 60% of the total cases, and the average age of the diagnosed was 31. Sixty percent of all lesions were found in the right cerebral hemisphere and 40% each in parietal and frontal lobe, which was found to be the highest incidence. The order of manifestated neurologic symptoms and signs was, headche, hemorrhagic symptoms, disturbance of consciousness, motor and sensory deficit, seizure and bruit. Sixty eight percent of the whole cases had evidence of hemorrhage and initial hemorrhage occurred at ages in such percentage as follows, 39.4% each between the ages of 21 and 30, and 30 and 40, and the percentage of hemorrhage among those bleow 40 was 88.2%. Of the 52 percent operated cases, there was no death. The results of operation were, improved 69.2%, 15.4% each in unchanged and worsened.

          黃酸第一鐵로부터 含水酸化鐵生成에 關한 硏究

          성주경,설수덕,황용길,Sung Joo Kyung,Suhl Soo Duk,Whang Yong Kil 대한화학회 1975 대한화학회지 Vol.19 No.2

          황산제일철을 원료로 해서 함수산화철 안료를 제조하기 위한 실험이다. 황산제일철을 암모니아로 중화해서 Mohr's salt(ferrous ammonium sulfate)을 만들고 Mohr's salt의 농도를 Fe(II) 이온농도, 14${\sim}$72g/l, 수소이온농도를 pH3 또는 6으로 조절한뒤, 반응온도는 $90{\sim}100^{\circ}C$로 일정하게 유지하고 반응시간 2시간, 3기압으로 공기 가압한 결과는 다음과 같다. Mohr's salt의 농도가 진하고, 중성으로 갈수록 함수산화철의 수득율이 증가되며, Mohr's salt 농도가 Fe(II) 이온농도, 42.81g/l 일때, 91.5% 이상의 수득율을 얻었다. 이렇게하여 생성된 함수산화철의 결정형은 $\alpha$-goethite형이며, 색상도 천연 ${\alpha}$-goethite와 유사하였다. 이것을 $500^{\circ}C$로 하소(calcination)하니 미려한 적갈색을 띤 ${\alpha}-Fe_2O_3$가 생성되었다. The formation of iron oxide hydroxide in a ferrous sulfate was studied in different contents of iron in the solution at a temperature range of 90 to $100^{\circ}C$ under 1${\sim}$3 atmospheres. The Mohr's salt thus formed was hydrolyzed under 1 to 3 atmospheres, in 14 to 72 g/l of iron content in the solution pH 3 or 6 for two hours at 90 to $100^{\circ}C$. The results obtained was as follows; 1) In Mohr's salt solution, as the iron content was increased, with decreasing the concentration of hydrogen ion, the yield of iron oxide hydroxide was gradually increased. 2) When iron content in Mohr's salt solution was 42.81 g/l, 91.5% of iron was recovered in the form of $\alpha$-goethite similar to yellow grade of natural goethite. 3) When $\alpha$-goethite obtained was calcined of $500^{\circ}C$, it was turned into ${\alpha}$-ferric oxide with a redish brown colour.

          황산제1철의 乾濕式에 의한 酸化反應에 對한 硏究

          설수덕,성주경,황용길,Soo Duk Suhl,Joo Kyung Sung,Yong Kil Whang 대한화학회 1977 대한화학회지 Vol.21 No.2

          황산제 1철을 전기로내에서 하소(瑕燒)시키고, 물에 침출시켜 몰비(Fe(III)/Fe(II))를 변화시킨 각각의 수용액을 가수분해하여 산화철 생성반응을 검토하였다. 하소온도가 증가함에 따라 소광(燒鑛)중의 Fe(III)/Fe(II)비가 증가하였고, $500^{\circ}C$에서 1시간 가량 하소시킨 시료가 등몰이 됨을 알았다. 등몰로 형성된 시료를 20% 수용액으로 만든 다음 pH 7 ∼ 8로 조절하고 반응온도 $100^{\circ}C$, 가압솥내 압력 3기압 및 반응시간 2시간으로 하여 가수분해 하였더니 진한흑색의 산화철이 93% 이상 생성되었다. A study on the formation of black iron oxide was carried in differents of Fe(III), Fe(II) ion in the aqueous solution that iron(II) sulfate was calcined under various temperature and leached in water. The results obtained was follows; (1) It was found that the sample calcined in an electric muffle furnace maintained at $500^{\circ}C$ for 1 hour and leached in water was equivalent mole (Fe(III) /Fe(II) = 1) in 20% aqueous solution. (2) When the above mentioned solution was hydrolyzed at pH range of 7 to 8 for 2 hours at $100^{\circ}C$, 93% and over of iron was recovered in the form of ${\alpha}-Fe_3O_4$ with a black colour.

          자발성 척수내혈종 - 증례보고 -

          황정현,성주경,황성규,함인석,박연묵,김승래,Hwang, Jeong Hyun,Sung, Joo Kyung,Hwang, Sung Kyoo,Hamm, In Suk,Park, Yeun Mook,Kim, Seung Lae 대한신경외과학회 2000 Journal of Korean neurosurgical society Vol.29 No.3

          Hematomyelia is an extremely rare condition that cause severe neurological symptoms. We reported 4 cases of spontaneous hematomyelia, two cases of cavernous angioma and two cases of hematoma. In all patients, the clinical course was progressive ; motor and sensory abnormalities below the lesion and voiding difficulties were the common presenting symptom complex. The preoperative diagnosis was made by magnetic resonance imaging and the all patients underwent surgical exploration. Complete removal of hematoma was done in 3 patients and complete evacuation after aspiration of hematoma were performed in one patients. Neurological function did not worsen postoperatively in any patients. The early diagnosis with magnetic resonance imaging and immediate surgical treatment of the hematoma and the associated vascular malformation are considered to be the best way to halt the progression of the disease.

          Triterpene glycosides with stimulatory activity on melanogenesis from the aerial parts of Weigela subsessilis

          원유미,성주경,김재림,김희성,송혁환,김두영,김정희,오세량,조현우,조정희,이형규 대한약학회 2015 Archives of Pharmacal Research Vol.38 No.8

          Three new triterpene glycosides (Lonicerosides K, L and M) and 11 known compounds were isolated from the aerial parts of Weigela subsessilis. Among the known isolated compounds, loniceroside A, sweroside, kaempferol-3-O-glucopyranoside 600-(3-hydroxy-3-methylglutarate), kaempferol-3-O-acetylglucoside and grandifloroside were reported for the first time in a Weigela genus plant. Their chemical structures were identified using extensive spectroscopic analysis including two-dimensional (2D)-NMR experiments, HR-ESI-QTOF-MS and comparison with reported data. Among these compounds, lonicerosides A and L had potent melanogenesis stimulatory activity in murine B16F0 melanoma cells. The structural relationship of active compounds was discussed.
