최정문,이진성,이상호 고신대학교 의과대학 2009 고신대학교 의과대학 학술지 Vol.24 No.2

E형 간염은 수인성 바이러스 간염으로 산발적으로 발생되며, 이차적인 사람간 전파는 없다. 진단 방법은 HEV Ab IgM 이나 PCR로 혈청이나 분변에서 HEV genome을 발견한다. 1~4% 에서는 급성 간부전이 생기며 임산부나 이전에 간 질환이 있었던 환자에게는 전격성 간염이 생길 가능성이 높다. 현재, 국내에서 E형간염에 대한 사례보고가 있다, 그러나 E형간염에서 급성신부전을 동반한 증례는 없었다. 해외에서는 비핍뇨성 급성신부전과 동반된 E형간염이 보고된 적이 있다. 저자들은 E형 간염과 관련된 핍뇨성 급성신부전 환자 1예를 경험하였기에 문헌고찰과 함께 보고하는 바이다 Hepatitis E is water-borne viral hepatitis similar to hepatitis A and an endemic disease. Most cases of hepatitis E in industrialized countries are described in immigrants and visitors of endemic areas or are thought to be spread zoonotically(commonly swine). Hepatitis E is self-limited. But it can be followed by acute liver failure. Fulminant hepatitis is more likely in those who are pregnant or have preexisting liver disease. The diagnosis of hepatitis E is based upon the detection of its genome in serum or feces by PCR or the antibody(IgM) of hepatitis E virus. We report a case of oliguric acute renal failure associated with hepatitis E.

In Korea, EMT have two classified subgroup of first and second degree : EMT-P, and EMT. For the beginning, authorization of the first EMT was made in this year through the EMT educational program. There are 8 items which EMT can perform the treatment without the supervision by a physician. But there was no previous report of pertinent assesment of treatment performed by the EMT. There upon authors have conducted review of assessment done by the EMT in EC setting, and proposed the following treatment application can be used by EMT at the field of accident. The study materials include adult trauma patient older than 15 years, and sustained trauma within 48 hours before visiting Ewha University DongDaeMoon Hospital Emergency Deparment. The duration of study was from Apr. 1 1995 to Aug. 31 1995. the study was conducted by 5 certified EMT. The EMT's performance was evaluated by the attending Emergency Medicine physician. The result were as followings ; 1. Among the total 5532 ED visiting patients during the study period, 1267 were adult trauma patients who recieved treatment within 48 hours of injury. 2. Among 1222 out of 1267 patients have completed performed survey. 3. Male to female ratio was 2.6 : 1, age distribution was from 15 to 87 years old and mean age was 34.6 years old. 4. The MOI showed : MVA (33.1%), blunt trauma (29.9%), slip down (16.8%), penetrating injury(15.4%), and miscellaneous (5.7 %), burn (3.1%), falling down injury(2.9 %), bite injury(1.1%) in order. 5. There were 437 cases of survey completed by the EMT. For assessment of mental status of 3 different method : AVPU, 5 scale mental status and GCS, were correlated with EM physician with 99.1%, 98.6%, 97.7 %, respectively. 6. For 320 out of 437 cases of survey completed, 319 patients recieved treatment by the EMT within 30 minute and 1 patient between 30 to 60 minute of an ED arrival. 7. For those 437 cases of survey completed, 266 patient (60.9%) had adequate treatment and 54 patients (12.4%) had inadequate treatment. 67 patient (15.3%) did not received treatment but it was adequate inway, and 50 patients (11.9%) did not received treatment even though patient required treatment. In cases of adult trauma patients, EMT's mental status assessment was correlated with EM physician's assessment. But treatment done by EMT without the supervision of EM physician was adequate only in 76.2 %. Therefore, continuous education and assessment of treatment performed by EMT in needed to improve field treatment by EMT future.

Backgrounds and Objectives: Vascular dementia is a group of dementing disoders arising from various stroke syndrome. Among these. subcortical ischemic vascular dementia (SIVD) is regarded as a relatively distinct clinical entity. However, MRI patterns of SIVD are not homogenous. In some patients, lacunes are dominant, and in others, subcortical white matter changes are. This study was designed to compare risk factor profiles between SIVD with and without multiple lacunes. Methods: We divided 47 subjects (22 males, mean age. 68 years) recruited from VADAPET (Multicenter Trial For Evaluation Of The Changes In the PET Images Of Subcortical Vascular Dementia Patient) study into two groups one with more than 5 lacunes in deep gray matter (lacune group) and the other with 5 or less(non-lacune group) Clinical characteristics and laboratory findings of two groups were compared. Results: Nineteen of 47 patients (40%) belonged to the lacune group. The lacune and non-lacune groups d d not differ in the following variables: age, hypertension, diabetes mellitus, hyperlipidemia heart disease, history of stroke or TIA, history of trauma or major surgery, family history of hypertension stroke, or dementia, age at diagnosis of dementia, body mass index, white blood cell count, ESR, CRP, fibrinogen, hemoglobin A1C, total cholesterol. LDL cholesterol creatinine, proteinuria, glucosuria, and microhematuria. However, male sex, smoking alcohol. hemoglobin, and HDL cholesterol were possibly associated more with lacune group SIVD than with non-lacune group (p<0 1) Multivariate analyses revealed that smoking, hemoglobin, and HDL cholesterol were independent predictors of SIVD with multiple lacunes Conclusion: Our study suggests that SIVD with multiple lacunes may be significantly different in smoking habits hemoglobin, and HDL cholesterol from SIVD without multiple lacunes.

MPTP 독성물질이 도파민성 신경세포에 선택적으로 작용하여 산화성 손상에 의한 신경세포사를 일으키는 것을 이용하여 파킨슨병의 동물모델을 만들고, 이를 통해서 아폼토시스를 비롯한 포사의 기전에 대한 연구 및 너코틴의 신경세포 보호효과 여부를 판정하는 실험을 병행하고자 하였다. 파킨슨꾐의 동물모델을 MPTf 독성 물질을 이용하여 확립하였으며, MPTP(30mgag, i.p.)를 투여한 후 1, 2,3, 4, 5일째 흑질 조직을 채춰하여 tarm로 박걸하여 tyrosine hydroxylase 면역조직화학염색을 수행하여 cell countif우한 결과, control은 57.635ce11s, 1일째 친.OfDells,2일째 57.9±6cells,3일릴 없.3±죠ells, 4일째 49.0츠3cells, 5일째 39.4±Scells료 4, 3일째 뚜렷한 신경세포 수의 감소를 보였다. 신경세포사 기전 규명을 위한 아폼토시스 분걱에서는 벼PTP 투여 후 1, 2, 3, 4, 5일째 조직을 채취하여 Hoechst staining, TUNEL staining을 수곡하였는데 양성 반응을 보인 신경세포는 관찰되지 않아. 아폼토시스로 인한 세포사가 관찰되지 않았다. bIPTP 파킨슨병 동물모델에서 nicotine 보호효과 탐색에 관한 실험은 nicat푸e 0.2mgAg을 5일 퐁안 투여 후 리『fP(30mgag)를 CS7Bt/6 마은스에 복강 내주사로 nicotine과 병용 투여한 후 1, 2, 3, 4, 5일째 뇌를 적출하땄다. 신경세포사가 뚜렷이 관찰되기 시작하는 4, 5일째의 신경세포 수의 감소 정도를 20. 30% 정도 약화시키는 경향을 보였으나, nicotine 보호효과에 대한 추가 실헝이 현재 수행 중에 있다. The cause of Parkinson's disease (PD) is largely unknown. However, free radical toxicit? may plaf a role ip. the degeneration of substantia nigra, which is the Hajorfocus of pathological damages in PD. Recently, a neuroprotective effect of nicotine in PD has been suggested. Therefore, the mechanism of neurodegenerafion and protective potential o( nicotine in PD were investigated in the experimental modeB of Pll using a neurotoxin, C57BL/6mice were administered with 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP, 30 mg/kg,j.p.). The degree of neurodegenerafion was determined by immunohistochemical stainiHB oftyrosine hydroxylase (TH). TH-positive cells on nigral sections were found 56.0 ±4, 57.9 ±6,52.315ce11s, 49.0±3cells, and 39,4±Scells at days 1, 2, 3, 4, 5, respectively (controls : 57.6±Scells). Hoechst and TUNEL staining showed no evidence of apoptosis. The exandnation on themice co-adrunistered with nicotine(0.2mgAg) and MPTP(30mgag) revealed a tendency ofnicotine protective effects. At days 4 and 5, the degree of TH-positive cells was decreased by20-30%, In corclusiffn, the role of apoptosis was not evidenced in this MPTP modeB of PB.The possible proteccon by nicotine should be elucidated with further studies.

<P>Nanoscale alloys attract enormous research attentions in catalysis, magnetics, plasmonics and so on. Along with multicomponent synergy, quantum confinement and extreme large surface area of nanoalloys offer novel material properties, precisely and broadly tunable with chemical composition and nanoscale dimension. Despite substantial progress of nanoalloy synthesis, the randomized positional arrangement and dimensional/compositional inhomogeneity of nanoalloys remain significant technological challenges for advanced applications. Here we present a generalized route to synthesize single-crystalline intermetallic nanoalloy arrays with dimensional and compositional uniformity via self-assembly. Specific electrostatic association of multiple ionic metal complexes within self-assembled nanodomains of block copolymers generated patterned monodisperse bimetallic/trimetallic nanoalloy arrays consisting of various elements, including Au, Co, Fe, Pd, and Pt. The precise controllability of size, composition, and intermetallic crystalline structure of nanoalloys facilitated tailored synergistic properties, such as accelerated catalytic growth of vertical carbon nanotubes from Fe–Co nanoalloy arrays.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/nalefd/2013/nalefd.2013.13.issue-11/nl403542h/production/images/medium/nl-2013-03542h_0005.gif'></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/nl403542h'>ACS Electronic Supporting Info</A></P>
