송명종,한민우,양혜정,이대영,노영덕,백남인 경희대학교식량자원개발연구소 2007 硏究論文集 Vol.26 No.1
피칸(Carya illinoensis C. Koch) 열매를 80% MeOH로 추출하고, 추출물을 극성에 따라 n-hexane, CHCl_(3), EtOAc, n-BuOH 및 물로 분배, 추출하였다. 이 중 EtOAc분획으로부터 silica gel column chromatography를 반복하여 4종의 지질화합물을 분리하였다. 분리된 화합물 화학구조는, NMR 및 MS 등의 스펙트럼을 해석하여 oleic acid methyl ester, linoleic acid methyl ester, β-sitosterol, daucosterol(3-O-β-D-glucopyaranosyl β-sitosterol)으로 동정하였다. Carya illinoensis C. Koch was extracted with 80% aqueous MeOH, and the concentrated extract was partitioned with n-hexane, CHCl_(3), EtOAc, n-BuOH and H_(2)O, successively. From the EtOAc fraction, four compounds were isolated through the repeated silica gel column chromatographies. From the results of physico-chemical data including NMR, MS and IR, the chemical structures of the compounds were determined as oleic aicd methyl ester(1), linoleic aicd methyl ester(2), β-sitosterol(3), and daucosterol(4). They were the first to be isolated from C. illinoensis.

We examined 1,856 patients who visited Won Kwang Neuropsychiatric hospital since July 11 of 1984(since the hospital opened) until June 11 of 1986. We researched diagnostic and other distributions of inpatients and outpatients. The study revealed as follows : 1. Of total patients males visited this hospital more than females as 52.7%. Most of them(67.1 %) resided in Iri, Iksan and Kimje. In the point of insurance, insured patients and uninsured patients except medicaids were 73 %. Males(60%) were more insured medically than females (55.4%). While insured patients relatively resided in urban area, but uninsured patients except medicaids did in rural area. 2. Of outpatients neurotic disorder was the most as 35.1%, secondly schizophrenic disorder and thirdly affective disorder, but of inpatients schizophrenic disorder was the most as 41.4%, secondly neurotic disorder thirdly affective disorder. 3. Alcohol abuse (98.2 %), paranoid disorder, convulsive disorder and child mental disorder were mostly found in males, but neurotic disorder (59 .6 %), affective disorder and other psychotic disorder were mostly found in females. 4. In unmarried ones schizophrenic disorder ( 43 .6 %), neurotic disorder, other psychotic disorder were common, but in married ones neurotic disorder (55.1 %), schizophrenic disorder, affective disorder were common. 5. On the distribution of age schizophrenic disorder was found the most in the twenties (28.4 %), next in the thirties and in the forties, but neurotic disorder was found the most in the thirties, next in the twenties and in the forties. 6. On the distribution of age at onset schizophrenic disorder develops mostly during the twenties (45.5 %), secondly during the teens and thirdly during the thirties, but neurotic disorder develops mostly during the thirties and the twenties (53.1 %). 7. On the duration of hospitalization 34.4% of the patients was hospitalized during less than 15 days, 22.0% during 60-90 days and 80.4% during less than 3 months. 8. In the result of treatment 41.2% of the patients was improved and 31.7% a little improved. In total 72.9% of the patients got helped therapeutically.

It is hardto make a decision of what route we will select for endotracheal intubation at open reduction of oral and maxillofacial trauma. In the patients with fractures of multiple facial bones combined with fracture of crainal basal bone, intermaxillary fixtion makes oro-endotracheal intubation impossible. And the possibility of injury to the fracture site of crainal basal bone and the impossibility of reconstruction of naso-orbito-ethmoidal(NOE) complex fractures also make the naso-endotracheal intubation difficult. But it is not easy to select the tracheostomy because of its several complications and abhorrences. For above reson, Altermir introduced submental route for endotracheal intubation as new technique in 1986 and Green etc. modified this technique in 1996. The purpose of this article is to evaluate the efficiency of submental route for endotracheal intubation after experience of 10-clinical cases for variable reasons with review of articles.

The serum γ-GTP activity was measured by modified Orlowski`s method in 23 patients with acute intrahepatic cholestasis(13 cases of acute hepatitis, 7 cases of acute cholestatic hepatitis, and 3 cases of acute fulminant hepatitis) and 26 patients with extrahepatic cholestasis(7 cases of pancreatic head cancer, 2 cases of ampulla of Vater cancer, 6 cases of CBD malignancy, 7 cases of CBD stone, p cases of CBD ascaris, 1 case of clornochiasis and 1 case of sclerosing cholangitis). Forty persons with no liver problem servedas a control group. The results were as follows; 1) The mean value of serum γ-GTP in the control group was 36.13±11.83 U/L, and there was no significant difference between the two sexes. 2) In cases of acute intrahepatic cholestasis, serum γ-GTP activity was relatively low(acute cholestatic hepatitis 57,00±20.66 U/L and fulminant hepatitis 36.67±13.89 U/L) in spite of a marked increase in serum bilirubin concentration and alkaline phosphatase activity. 3) In cases of extrahepatic cholestasis, serum γ-GTP showed increased activity with mean value of 451.19±245.77 U/L together with elevation of serum bilirubin and alkaline phosphatase levels. 4) The ratio of γ-GTP to serum alkaline phosphatase in cases of acute intrahepatic cholestasis was markedly decreased as compared to that in cases of extrahepatic cholestasis(p$lt;0.001). This finding suggests that low γ-GTP activity is useful in the differentiation of acute intrahepatic cholestasis from extrahepatic cholestasis.

0.1N NaClO₄ 전해질중에서 백금과 이산화납 전극에 대한 요오드 이온의 전극반응을 삼각파 전위 주사법으로서 검토하였다. 그 결과는 다음과 같다. 백금전극에서는 0.65, 1.15와 1.4V vs. S.C.E에서 세개의 산화파가 형성되었으며, 이는 I₂, IO^-와 IO^-₃의 생성 전극반응에 기인하는 것이다. 이산화납 전극에서는 1.1과 2.25V vs. S.C.E.에서 I₂와 IO₃^-가 생성되는 전극반응이 일어났다. 백금과 이산화납 전극에서 모두 I^-이 흡착되며 I^-/I₂반응계는 가역적이었다. The oxidation of iodide at platinum and lead dioxide electrodes in O.1N NaClO₄, electrolytes were investigated using the cyclic voltammetric technique. Results are summarized as following: (I) At platinum electrode three anodic waves of I₂, IO^- and IO₃^- was formed at 0.65, 1.15 and 1.4V vs. S.C.E., respectively. (2) At lead dioxide electrode the formations of I₂ and IO₃^- occured at 1.1 and 2.25V vs. S.C E., respectively. (3) On both electrodes of platinum and lead dioxide iodide ions ere adsorbed and the reaction I^-/I₂ is proceeded reversibly.
