The present study investigated the habitats of Korean fir trees (Abies koreana E. H. Wilson) on Mt. Baekwun (Baekwun-san), determined the current distribution, quantified the contribution of biological and nonbiological environmental factors affecting the distribution, derived actual and potential habitats, presented a plan for the establishment of protected areas, applied RCP 8.5 climate change scenario to analyze the effects of climate change on the future distribution of Korean fir trees, and predicted future potential habitats. According to the results of the study, 3,325 Korean fir trees (DBH >= 2.5 cm) inhabited Mt. Baekwun, and their distribution area was approximately 150 ha. Populations of Korean fir trees were confirmed to exist at an altitude of 900 m above sea level and were distributed up to 1,200 m. Based on potential distribution, areas appropriate for habitation by Korean fir trees were analyzed to be 450 ha, three times the current distribution area, with a focus on Sang Peak (Sang-bong), Eokbul Peak (Eokbul-bong), Ddari Peak (Ddari-bong), and Dosol Peak (Dosol-bong). The forest stands near Sang Peak, the main peak, were evaluated as those with the most appropriate potential for the habitation of Korean fir trees, and populations of the trees tended to prefer the northern slope rather than the southern slope. When climate change scenario RCP 8.5 was applied and future potential distribution was analyzed, the habitats were expected to decrease in area to 20 ha by 2050, with a focus on Sang Peak, and areas appropriate for habitation were predicted not to exist by 2080. Judging from such results, as global warming accelerates, the habitats of Korean fir trees are clearly expected to move from lowlands to highlands.

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.

Vscularized calvarial bone flaps have been useful tools in the reconstuction of different type of bone defects in craniofacial surgery Vascularized bone transfer are often preferred to nonvascularized bone grafts because nonvascularized bone grafts are less resistant to infection, mot as mechanically strong, and do not survive well in a poorly vascularized bed. Potential advantages of vascularized outer table cavarial bone flap include proximity to the operative feild, membranous origin similar to that of the facial skeleton, maleability which allows for a variety of shapes and sizes, inconspicous donor sit scar. The following are the case reports of two patients who underwent craniofacial reconstruction suing vasularized outer table calvarial bone flap.

65세 여자 환자의 요 검체에서 vancomycin 내성 E. faecalis를, 욕창의 농에서 vancomycin 내성 E. faecium을 분리하였는데, 환자의 병력으로 미루어 미국에서 정착된 세균에 의하여 감염되었을 것으로 생각되었다. 분리 균주에 대한 vancomycin의 MIC는 각각 258과 32㎍/mL, teicopoanin은 0.25, 0.5㎍/mL이어서 VanB 표현형으로 추측되었다. 우리 나라에서의 VRE 확산을 예방하기 위한 조치의 일환으로서 의사를 포함한 병원 직원에게 VRE 감염증의 심각성을 홍보하여야 하며, 미생물검사실에서는 임상검체에서 분리된 장구균의 vancomycin 내성을 시험하고 장내 VRE 보균자의 주기적 검색이 필요하다고 사료되었다. Vancomycin-resistant Enterococcus faecalis and E. faecium were isolated from urine and decubitus ulcer discharge, respectively, from a 65-year-old woman. Proir to the transfer to this hospital in December, 1995, she had been admitted to the Chicago Rehabilitation Center in the U.S. for the treatment of olivopontocerebellar atrophy, quadriplegia, and neurogenic bladder. She was also treated with multiple antimicrobials including vancomycin for pneumonia at intensive care unit, which suggested that she acquired the organisms in the U.S. The minimal inhibitory concentrations of vancomycin and teicoplanin against the isolates were: E. faecalis 256 ㎍/mLand 0.5㎍/mL; E. faecium 32 ㎍/mL and 0.5 ㎍/mL, respectively. The susceptibility patterns suggest the isolates are vanB type. Although other species of vancomycin-resistant Enterococcus spp. were reported previously in Korea, these isolates may be the first vancomycin-resistant E. faecalis and E. faecium from clinical specimens.

It has been reported that vinblastine, anticancer drug, is a neuroteratogen inducing various neural malformations such as microcephaly and neural tube defect(NTD), but the study on the toxicity of neuroglial cells, especially type-1 astrocytes using culture system is not well established. In order to evaluate the cytotoxicity of vinblastine on cultured type-1 astrocytes of neonatal rat brain in vitro. MTT assay and also light and electron microscopic studies were carried out. The results were as follows: 1. MTT_90 and MTT_50 in cultured type-1 astrocytes were 1×10 exp (-1) μM and 1×10 exp (2)μM of vinblastine, respectively. 2. Vinblastine was highly toxic in cultured type-1 astrocytes(MTT_50 ≤ 100 μM). 3. In a light microscopy, cultured type-1 astrocytes showed decrease of cells in number, cytoplasmic perforation, vacuolization and cytoplasmic granulation after cultured type-1 astrocytes were treated with 1×10 exp (2)μM of vinblastine for 24 hours. Cultured type-1 astrocytes damaged by vinblastine showed degenerative changes of cells morphologically. 4. In an electron microscopy, increment of glial fibrillary acidic protein(GFAP), increased free-ribosomes, cisternal dilatation of rough endoplasmic reticulum (rER). few dense bodies and vacuoles were shown in cultured type-1 astrocytes treated with 1×10 exp (2)μM of vinblastine for 24 hours. The results indicate that vinblastine has markedly cytotoxic effect on the type-1 astrocytes of neonatal rat brain in vitro study.

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.

Platelet-Rich Plasma (PRP)가 토끼 척골의 분절 결손의 치료로 이식된 동종 장관골의 골유합에 미치는 효과

송주현,정진영,강용구,이한용,손문익,서상일 대한골절학회 2003 대한골절학회지 Vol.16 No.3

목적: 골종양 환자나 외상, 골수염, 인공관절 치환술 등의 환자 등의 환자 치료에 많이 사용하는 장관골의 동종 이식에 대한 PRP (Platelet-Rich Plasma)의 효과를 토끼를 이용한 실험으로 알아보고자 하였다. 대상 및 방법: 20마리의 토끼를 대상으로 각각에 일련번호를 붙이고, 각 토끼의 양측 척골에 약 2㎝ 길이의 골편을 얻어 장관골 결손을 만들고 동시에 동종 장관골을 얻어, 홀수 토끼의 척골 골편을 짝수 토끼의 골결손 분위에 이식하고, 반대로 짝수 토끼의 척골 골편을 홀수 토끼의 골결손 분위에 이식하였다. 그 후 각 토끼의 좌측 척골 이식 부위에는 아무런 처치를 하지 않고 대조군으로 삼고, 우측 척골 이식부에는 PRP 0.7cc를 처치하여 실험군으로 삼았다. 술 후 0, 4, 8, 12주에 골이식부에 대한 방사선 촬영을 통하여 골유합 성적을 평가 비교하였다. 결과: 실험군의 척골 분절 결손부에서는 대조군에서보다 동종 분절골 이식부의 골유합이 방사선학적으로 향상된 것을 관찰 할 수 있었다. 결론: 동종 장관골 분절 이식시 PRP를 병용하여 사용할 경우 더욱 효과적인 신생조직 형성을 유도할 수 있으며, 임상에도 유용하게 적용할 수 있으리라 사료된다. Purpose: The purpose of this study was to evaluate the effect of Platelet-Rich Plasma(PRP) on the healing of the allograft for the treatment of the segmental bone defect of the ulna in Rabbits. Materials and Methods: About 2 ㎝-sized segmental bone defects were created on both ulna of twenty rabbits. The rabbits were divided into two groups, even and odd number groups after numbering them from 1 to 20. The segmental bone from the odd numbered animal was transplanted to the even numbered animal, and the even numbered to the odd numbered. The left side of the ulna was grafted with a segmental allograft only. The right side of the ulna was grafted with a segmental allograft and 0.7cc of PRP. Radiographs obtained at 0, 4, 8, and 12 weeks postoperatively were graded for radiologic union. Result: The use of the combination of PRP and segmental allograft demonstrated improved healing on radiographic study compared with that demonstrated after use of allograft alone. Conclusion: The results of the study suggests that the use of the combination of PRP and segmental allograft can be considered as an alternative method to manage the segmental defect of the long bone.
