Objective : The lateral extracavitary approach(LECA) to the thoracolumbar spine is known as one of procedure which allows not only direct vision of pathologic lesion, but also ventral decompression, and dorsal fixation of the spine through the same incision. However, some drawbacks of LECA, including the technically- demanding, time-consuming, unfamiliar surgical anatomy and excessive blood loss, make surgeons to hesitate to use this approach. This study is to provide the surgical anatomy of LECA using cadavers, for detailed informations when LECA is considered for the surgery. Methods : We performed the 10 cadaveric studies, 7 male and 3 female, and careful dissection was carried out on right side of thoracolumbar region, except one for thoracic region. The photographs with micro-lens were taken to depict the close-up findings and for demonstrating detailed anatomy. Results : The photographs and hand-drawings demonstrated the relationships among the musculature, segmental vessels and nerve roots seen during each dissection plane. The lateral branches of dorsal rami of spinal nerve and the transverse process were confirmed to be the most important landmark of this approach. Conclusion : We concluded that detailed anatomical findings for LECA through this step-by-step dissection would be useful during operative intervention to reduce the intraoperative complications in LECA.

The objective of his study is to research the effect of the 'Dagagu' housing purchase and the public rental housing supply on the nearby community. In the case of public rental housing, many studies have demonstrated that the perception that a public rental house is a low income dwelling has an external effect on the residents immediately outside the area such as the perception of the lowering of house prices. However, an advanced research concerning the 'Dagagu' housing purchase and public rental housing has not been carried out because it has only recently been enforced. Through a survey conduced of residents who live nearby the 'Dagagu' housing purchase and public rental housing the aim of his study is to show how the residents perceive the renal houses and are influenced by them. At the same time, this study demonstrates the external effect of rental house supply by analyzing the housing price around the area. Most people who live in the near by 'Dagagu' housing purchase and public renal housing have a negative opinion of his housing because they believe that the residential prices will depreciate. However, only about 40% of the people felt that the residential price depreciation as a result of the 'Dagagu' housing purchase and public rental housing supply was not visible.

김상돈,지병철,이정렬,서창석,김석현,문신용,Kim, Sang-Don,Jee, Byung-Chul,Lee, Jung-Ryeol,Suh, Chang-Suk,Kim, Seok-Hyun,Moon, Shin-Yong 대한생식의학회 2010 Clinical and Experimental Reproductive Medicine Vol.37 No.1

목 적: 체외수정시술 시 황체기 보강은 근주, 경질, 경구 등의 다양한 방법으로 이루어지고 있는데, 경구 투여법은 환자의 순응도가 높고 비교적 안전한 방법이다. 본 연구에서는 황체기 보강을 근주로 시작하여 경구 투여로 전환하는 방법의 효용성과 전환 시기에 따른 결과를 비교 분석하고자 하였다. 연구방법: 2003년 9월부터 2009년 6월까지 분당서울대학교병원에서 체외수정시술을 시행받은 환자에서 배아 이식 후 태아 심박동까지 확인된 76주기를 대상으로 하였다. 과배란유도는 GnRH agonist long protocol (n=7) 또는 GnRH antagonist protocol (n=66)을 이용하였으며 3주기에서는 냉동배아 이식을 시행하였다. 황체기 보강을 위하여 난자 채취일부터 매일 progest in oil 50 mg을 근주하였고, 태아 심박동이 확인된 후 임신 6~7주 (n=17) 또는 8주 이후 (n=59)에 micronized progesterone (Utrogestan, Laboratoires Besins International, France) 300 mg을 매일 경구로 투여하였다. 결 과: 대상군 전체의 유산율은 3.9% (3/76)이었으며, 경구 투여 전환시의 임신 주수는 평균 8주 4일 (난자 채취일로부터 $46{\pm}5.8$일)이었다. 황체기 보강을 임신 6~7주 사이에 경구 투여로 전환한 17주기 중에서 1례의 자연유산이 확인되었으며 유산 시 주수는 9주 4일이었다. 8주 이후에 경구 투여로 전환한 59주기 중에서는 2례의 자연유산이 확인되었으며 (11주 3일, 11주 4일), 두 군의 자연유산율은 각각 5.6%와 3.4%로 두 군 간에 통계적으로 유의한 차이는 없었다 (p=0.678). 결 론: 체외수정시술 후 황체기 보강을 시행하는 경우 태아 심박동이 확인된 이후에 근주 투여를 경구 투여로 전환하는 방법은 비교적 낮은 유산율을 보임을 확인하였으며, 특히 8주 이전에 전환하는 것도 유용한 방법이라 사료된다. Objectives: The aim of this study was to assess appropriate time to convert intramuscular progesterone support to oral administration for luteal phase support in in vitro fertilization (IVF). Methods: Seventy-six cycles of IVF in which fetal heart beat was identified after treatment were included. Patients underwent controlled ovarian hyperstimulation with GnRH agonist long protocol (n=7) or GnRH antagonist protocol (n=66). Cryopreserved embryo transfer was performed in three cycles. Luteal support was initiated by daily intramuscular injection of progesterone, and after confirmation of fetal heart beat, converted to oral micronized progesterone (Utrogestan, Laboratoires Besins International, France) 300 mg daily before or after 8 gestational weeks. The oral progesterone was continued for 11 weeks. Results: Overall clinical abortion rate was 3.9% (3/76) and mean time to conversion was $8^{+4}$ gestational weeks ($46{\pm}5.8$ days after oocytes retrieval). The abortion rate was 5.6% (1/17) and 3.4% (2/59) in patients with conversion before 7 weeks and after 8 weeks, respectively, which were not statistically significant (p=0.678). The miscarriages were occurred at $9^{+4}$ weeks, $11^{+3}$ weeks and $11^{+4}$ weeks. Conclusion: Sequential luteal support using intramuscular and oral progesterone yields a relatively low clinical abortion rate. If fetal heart beat confirmed, sequential regimen appears to be safe and convenient method to reduce patients' discomfort induced by multiple injections.

기관지천식 환자의 기관지분비물내 총 IgE 항체치 연구에서 유도객담검사의 유용성

Background: IgE antibodies have been considered to play an important role in the pathogenesis of atapic asthma. However, there have been only few studies on the role of IgE in airway secretion in the pathogenesis of bronchial asthma. This might be partly due to difficulty in sampling of airway seceretion from asthmatic patients. Recently, sputum induction method by inhalation of nebulized hypertonic saline was developed, and proved to be valid and useful method for obtaining airway secretion from asthmatic patients for studying air- way inflammation. %jective and method: To evaluate the usefulness of sputum induction method for studying IgE antibodies in airway secretion from atopic asthmatic patients, total IgE levels in induced sputum from 54 atopic asthmatics were measured by enzyme-linked immunosorbent assay(ELISA) and tried to find an association with sputum eosinophilia. Result: Total IgE levels in induced sputum were significantly higher in atopic asthmatic patients(1.27+82.066 IU/ml) than in controls(0.203+0.291 IUgmP)(p<0.05). In atopic asthmatic patients, total IgE levels in induced sputum were not significantly different between patients with and without sputum eosinophilia(>5% of 200 counted leukocytes). There was a significant correlation of total IgE levels between induced sputum and serum in atopic asthmatic patients(r=0.60, p<0.05). Total IgE levels in induced sputum(1.278+ 2.066) were significantly higher than saliva sample(0.504 + 1.111 IU/ml) from atopic asthmatic patients(p<0.05). Conclusion '. These results suggest that total IgE levels are increased in the induced sputum of atopic asthmat,ic patients and sputum induction method is a useful tool for study- ing IgE antibodies in airway secretion from asthmatic patients.

김상돈,Sung Won Kim,Dong Kyoo Park 한국화학공학회 2013 Korean Journal of Chemical Engineering Vol.30 No.5

Pyrolytic kinetic parameters of Jatropha seedshell cake (JSC) were determined based on reaction mechanism approach under isothermal condition in a thermobalance reactor. Avrami-Erofeev reaction model represents the pyrolysis conversion of JSC waste well with activation energy of 36.4 kJ mol−1 and frequency factor of 9.18 s−1. The effects of reaction temperature, gas flow rate and feedstock particle size on the products distribution have been determined in a bubbling fluidized bed reactor. Pyrolytic bio-oil yield increases up to 42 wt% at 500 oC with the mean particle size of 1.7 mm and gas flow rate higher than 3Umf, where the maximum heating value of bio-oil was obtained. The pyrolytic bio-oil is characterized by more oxygen, lower HHVs, less sulfur and more nitrogen than petroleum fuel oils. The pyrolytic oil showed plateaus around 360 oC in distribution of components’ boiling point due to high yields of fatty acid and glycerides.

Oligodendrogiomas account for about 4 per cent of intracranial gliomas and surgery is known to be an essential first step to establish an accurate diagnosis and when oligodendrogliomas recur with or without anaplastic features after initial resection, radiation and chemotherapy consisting of the administration of procarbazine, lomustine, and vincristine are usually indicated. We report our experience of an excellent result with intraventricular methotrexate chemotherapy for a patient with disseminated anaplastic oligodendroglioma. A 29-year-old male patient presented with diplopia and headache for two months. MRI showed a irregular, faintly enhanced mass in the posterior fossa. The hisotological diagnosis was an anaplaplastic oligodendroglioma and he was treated with chemotherapy of PCV regimen and radiotherapy followed by surgery. CSF dissemination was revealed by a follow-up MRI during the period. Intraventricular methotrexate(0.175mg/kg) was given twice a week for 4 weeks through ommaya reservoir and the size of the multiple tumors was decreased significantly on follow-up MRI. This case report suggests that an aggressive treatment involving intravent-ricular chemotherapy may be helpful even when anaplastic oligodendrogliomas disseminates to leptomeninges.
