Investigation of meridian line and acupoints as anatomical entities should be very important, as acupuncture and meridian massage for medical purpose in the hospital or for skin care in beauty shop are each based on the traditional meridian theory. We isolated tubular structures under the skin of rabbits where the traditional meridian lines are located. The characteristics of these tubular structures isolated from the abdominal wall matches those of Bonghan tubes and Bonghan tubules found by Bong Han Kim. The Bonghan theory established by Bong Han Kim suggests that meridian lines consist of Bonghan tubes and Bonghan tubules. We could observe the presence of large cells inside the Bonghan tubule and the presence of small granules referred to as Sanal in Bonghan theory inside the striae consisting of the Bonghan tubules. Present research suggests that there exist a third unique tubular structure where Sanals flow other than Bonghan tube and Bonghan tubules.

연구목적 : 본 시험의 목적은 임상시험 시작전에 연구자들을 대상으로 PANSS Workshop을 통하여 PANSS, ESRS에 대한 국내에서의 표준화 작업을 구축하고 새로운 정신병 치료제인 리스페리돈의 효과와 안정성을 재확인하여 리스페리돈 사용에 대한 적정화를 이루는데 있다. 연구방법 : 1996년 4월부터 1996년 9월까지 국내 39개 대학병원 정신과에 입원중인 혹은 증상이 악화되어 입원하는 정신분열병 환자 377명을 대상으로 다시설 개방 연구를 시행하였다. 1주일간의 약물 배설기간을 가진후, 리스페리돈을 8주간 투여하였고, 기준점, 1주, 2주, 4주, 그리고 8주후에 평가되었다. 용량은 제1일에는 리스페리돈 1mg씩 1일 2회, 제2일에는 2mg씩 1일 2회, 제3∼7일에는 3mg씩 1일 2회 투여하였다. 이후 환자의 임상상태에 따라 임의로 증량할 수 있으며, 최대 일일 16mg을 초과하지 않도록 하였다. 추체외로 증상을 조절하기 위한 투약을 허용하였다. 임상증상 및 부작용의 평가는 PANSS(Positive and Negative Syndrome Scale), CGI(Clinical Global Impression) 그리고 ESRS(Extrapyramidal Symptom Rating Scale)을 사용하였다. 연구결과 : 377명중 343명(91%)이 8주간의 연구를 완결하였다. 치료 종결시점인 8주후 PANSS 총점수가 20% 이상 호전된 경우를 약물 반응군으로 정의할때, 약물반응군은 81.3%였다. 리스페리돈에 반응하는 예측인자로는 발병연령, 이전의 입원 횟수, 유병기간이 관련 있었다. 리스페리돈은 1주후부터 PANSS양성, 음성, 및 일반정신병리 점수상에 유의한 호전을 보여 효과가 빨랐다. CGI의 경우도 기준점에 비해 1주후부터 유의한 감소를 나타내었다. ESRS의 경우, 파킨슨 평가점수는 기준점과 비교해 투여 1주, 2주, 4주후 유의하게 증가되었다가 8주후 기준점과 차이가 없었다. Dystonia 평가점수는 1주후만 유의한 증가를 보였으며, dyskinesia 평가점수는 유의한 차이가 없었다. 혈압, 맥박수의 생명징후 및 일반 혈액학 검사, 생화학적 검사, 심전도 검사에서 유의한 변화는 없었다. 결 론 : 이상의 다시설 개방 임상 연구를 통해 리스페리돈은 정신분열병 환자에서 양성증상뿐만 아니라 음성증상 및 전반적인 증상에도 효과적인 것으로 사료된다. 보다 명확한 평가를 위해서는 다른 항정신병약물과의 이중맹검 연구가 필요할 것으로 생각되며, 또한 장기적 치료에 대한 평가도 함께 이루어져야 하겠다. Objective : The purpose of this study was to investigate the efficacy and safety of risperidone in the treatment of Korean schizophrenic patients. Method : This multicenter open study included 377 schizophrenic patients drawn from 39 university hospitals. After a wash-out period of 1 week, the schizophrenic patients were treated with risperidone for 8 weeks and evaluated at 5 points ; at baseline, and 1, 2, 4 and 8 weeks of treatment. The dose was increased from 2mg/day(1mg twice daily) to 6mg/day(3mg twice daily) during the first week and adjusted to a maximum of 16mg/day over the next 7 weeks according to the patient's clinical response. Medication to control extrapyramidal symptoms was permitted. The psychiatric and neurological status of the patients was assessed by PANSS, CGI, and ESRS scales. Results : 343(91%) of 377 patients completed the 8-week trial period. Clinical improvement, as defined by a 20% or more reduction in total PANSS score at end point, was shown by 81.3% of patients. The predictors of response to risperidone were associated older age, shorter duration of illness, fewer previous hospitalization. Risperidone had rapid onset of action ; a significant decrease of the total PANSS and three PANSS factor(positive, negative, general), and CGI was already noticed at the end of first week. For the ESRS, parkinsonism rating scores were significantly increased until week 4 comparing with baseline. Dystonia rating scores were significantly increased until week 1, and dyskinesia rating scores were not significantly changed during the study. Laboratory parameters including vital sign, EKG, hematological, and biochemical values showed no significant changes during the trial. Conclusions : This study suggests that risperidone is generally safe and effective against both the positive and negative symptoms in our group of patients.

목적 : 본 연구는 수근관 증후군의 발생위험이 높은 작업형태에 종사하는 상지 단순반복작업근로자로서 육류 및 어류 가공 사업장과 목재소 근로자에서 근전도검사를 이용하여 수근관 증후군의 유병률을 조사하고자 하였다. 방법 : 상지 단순반복작업근로자로서 육류 및 어류 가공 사업장 근로자 69명과 목재소 근로자 17명을 실험군으로, 관리직, 경리, 경비등 상지의 단순반복작업이 없는 근로자 28명을 대조군으로 선정하여, 작업적 및 병력조사, 이학적 검사와 근전도검사를 통해 수근관 증후군의 유병률을 조사하였다. 결과 : 수근관 증후군의 유병률은 육류 및 어류 가공 사업장과 목재소에서 각각 26.09 % (18명)와 29.41 %(5명)로 조사되었으며, 육류 및 어류가공사업장과 목재소 근로자를 '7년 이상과 미만의 작업기간'으로 층화하여 비교한 결과 '상지부위의 통증 호소 유무', 'Visual Analogue Scale(VAS: 총 10점) 4점 이상 여부', 'Tinel teat 양성 유무', 'Phalen test 양성 유무'는 모두 단기 작업근로자군에서 양성의 빈도가 증가되었고 '수근관 증후군 유무'는 장기작업근로자군에서 양성의 빈도가 증가되었다. 결론 : 육류 및 어류 가공 사업장과 목재소의 수근관 증후군 유병률은 각각 26.09 %와 29.41 %로 육류 및 어류 가공 사업장과 목재소는 1996년 OSHA가 지정한 바와 같이 위험한 작업요인이 있는 작업장으로 분류하여 관리되어야 할 것으로 생각된다. Objectives : This study was carried out to survey on the prevalence of Carpal Tunnel Syndrome(CTS) in high risk jobs(meat and fish processing plant and wood plant), by application of Nerve Conduction Study(NCS), a confirmatory diagnostic method. Methods : Experimental group was 69 workers sampled from meat and fish processing plants and 17 workers sampled from wood plants, who were simple, repetitive workers using upper extremities and control group was 28 workers sampled from managers, secretaries and keepers. All employees were examined through work history, physical examination and NCS. Results : 18 workers(26.09%) in meat and fish processing plants, and 5 workers(29.41%) in wood plants had compatible findings to NIOSH diagnostic criteria for CTS. The experimental group had more symptoms (complaint of upper extremities, Visual Analogue Scale ≥4(VAS: total 10 point)), signs(Tinel and Phalen test) and prevalence of CTS than control group(p<0.05). The prevalence of symptoms and signs were higher in short term workers(<7 years), but the prevalence of CTS was higher in long term workers(≥7 years). Conclusions : The prevalence of CTS in meat and fish processing plant and wood plant were 26.09% and 29.41% respectively. Authors propose that meat and fish processing and wood plants should be managed as a risk job category which were designated by OSHA in 1996

This experiment was carried out to investigated the effects of levels of mineral nitrogen under various cutting systems on the nutritive value and nutrient yields of orchardgrass (Dactylis glomerata L.) during harvested years in 1993-1995. The contents of crude protein (CP), total digestible nutrients (TDN), relative feed value (RFV) and annual nutrient yields in relatively wet year (1993) were significantly higher than those in the other harvested years, but the tendency of contents of acid detergent fiber (ADF) and neutral detergent fiber (NDF) were against. The contents of CP, TDN, RFV of all cutting frequencies were highest at the last cut, but lowest at the 2nd cut. The annual nutrient yields were highest at the 1 st cut in 3 cuttings, and at the 2nd cut in 4 and 5 cuttings, respectively. Significantly higher contents of CP in all cutting frequencies appeared in according to increase the levels of mineral nitrogen, but the contents of ADF were lower with nitrogen fertilization of 60 kg ha^(-1) cut^(-1) in 4 and 5 cuttings than those in non-fertilized plots. Higher efficiencies of dry matter production (kg DMY kg^(-1) N), crude protein production (kg CPY kg^(-1) N) and total digestible nutrients production (kg TDNY kg^(-1) N) in response to mineral nitrogen fertilization were recorded as 12.9, 1.4 and 7.6 kg at level of 360 kg ha^(-1) in 3 cuttings, 27.3. 2.7 and 16.0 kg at level of 120 kg ha^(-1) in 4 cuttings, 20.5, 2.0 and 12.7 kg at level of 360 k, ha^(-1) in 5 cuttings, respectively. In all treatments, negative correlation between CP and ADF or NDF appeared (P<0.001). Positive correlations were recorded between CP and TDN or RFV. and among TDN and nutrient yields (P<0.01).

광릉 슈퍼사이트에서 대기와 식생간의 에너지와 물질교환 규명은 지형과 식생의 복잡성으로 인해 많은 기술적인 어려움에 직면하고 있다. 따라서 KoFlux 연구에서는 상호보완적인 다중 분야의 연구를 통해 이러한 어려움을 극복하기 위한 시도를 해 오고 있다. 본 논문에서는 현재 진행중인 KoFlux 연구의 예비결과 중 특히 광릉사이트에서의 물/탄소수지, 물과 탄소순환의 상호관련성 그리고 몬순기후하의 생태계에서 탄소순환에 미치는 수문학적 요인의 중요성에 대해 중점적으로 논의하고자 한다. 광릉낙엽활엽수림의 순생태생산량 (NEP)은 광범위한 생태학적 연구결과에 따르면 약 ~2.6 t C/ha/y로 예상된다. 이를 미기상 플럭스 관측 결과와 함께 고려할 때 광릉 산림은 탄소의 중요한 육상흡원으로서 기능함을 예상할 수 있다. 다양한 생태수문 관측에 의해 규명된 유역단위 물수지에 의하면 연단위 전체강수량의 약 30-40%가 증발산 (ET)에 해당함을 나타내고 있다. 광릉산림의 대표적인 수종인 졸참과 서어나무의 잎에서 얻어진 탄소 안정동위 원소 조성에 근거하여 계산된 식물 성장기간의 평균 물 이용효율(WUE)은 약 ~12 μmol CO2/mmol H2O에 해당된다. 얻어진 증발산량과 물이용효율은 유역단위의 생태계 생산량을 산출하는데 이용될 수 있다. 나이테 성장량과 토양호흡량의 연단위 변화는 강수량과 강수의 패턴에 의해 크게 영향을 받음을 보이고, 이는 몬순기후에 영향을 받는 동아시아 지역 생태계에서 탄소 순환과정이 수문학적 조건과 밀접한 상관관계를 가짐을 지시한다. 연구지역의 공간적 특성을 정량화하기 위해 관측지의 구조 및 기능적 단위를 규명하기 위한 연구가 진행되고 있고 이를 통해 서로 다른 시공간 규모에서 진행되고 있는 연구의 결과물을 체계적으로 연결 통합하고 나아가 보다 광역적인 규모에서 대표적인 물/탄소 수지를 산출하기 위한 연구가 시도되고 있다. KoFlux Gwangneung Supersite comprises complex topography and diverse vegetation types (and structures), which necessitate complementary multi-disciplinary measurements to understand energy and matter exchange. Here, we report the results of this ongoing research with special focuses on carbon/water budgets in Gwangneung forest, implications of inter-dependency between water and carbon cycles, and the importance of hydrology in carbon cycling under monsoon climate. Comprehensive biometric and chamber measurements indicated the mean annual net ecosystem productivity (NEP) of this forest to be ~2.6 t C ha-1 y-1. In conjunction with the tower flux measurement, the preliminary carbon budget suggests the Gwangneung forest to be an important sink for atmospheric CO2. The catchment scale water budget indicated that 30~40% of annual precipitation was apportioned to evapotranspiration (ET). The growing season average of the water use efficiency (WUE), determined from leaf carbon isotope ratios of representative tree species, was about 12 μmol CO2/mmol H2O with noticeable seasonal variations. Such information on ET and WUE can be used to constrain the catchment scale carbon uptake. Inter-annual variations in tree ring growth and soil respiration rates correlated with the magnitude and the pattern of precipitation during the growing season, which requires further investigation of the effect of a monsoon climate on the catchment carbon cycle. Additionally, we examine whether structural and functional units exist in this catchment by characterizing the spatial heterogeneity of the study site, which will provide the linkage between different spatial and temporal scale measurements.

Son, Jun Seong,Song, Jae-Hoon,Ko, Kwan Soo,Yeom, Joon Sup,Ki, Hyun Kyun,Kim, Shin-Woo,Chang, Hyun-Ha,Ryu, Seong Yeol,Kim, Yeon-Sook,Jung, Sook-In,Shin, Sang Yop,Oh, Hee Bok,Lee, Yeong Seon,Chung, Doo The Korean Academy of Medical Sciences 2010 JOURNAL OF KOREAN MEDICAL SCIENCE Vol.25 No.7

<P>Recent changes in healthcare systems have changed the epidemiologic paradigms in many infectious fields including bloodstream infection (BSI). We compared clinical characteristics of community-acquired (CA), hospital-acquired (HA), and healthcare-associated (HCA) BSI. We performed a prospective nationwide multicenter surveillance study from 9 university hospitals in Korea. Total 1,605 blood isolates were collected from 2006 to 2007, and 1,144 isolates were considered true pathogens. HA-BSI accounted for 48.8%, CA-BSI for 33.2%, and HCA-BSI for 18.0%. HA-BSI and HCA-BSI were more likely to have severe comorbidities. <I>Escherichia coli</I> was the most common isolate in CA-BSI (47.1%) and HCA-BSI (27.2%). In contrast, <I>Staphylococcus aureus</I> (15.2%), coagulase-negative <I>Staphylococcus</I> (15.1%) were the common isolates in HA-BSI. The rate of appropriate empiric antimicrobial therapy was the highest in CA-BSI (89.0%) followed by HCA-BSI (76.4%), and HA-BSI (75.0%). The 30-day mortality rate was the highest in HA-BSI (23.0%) followed by HCA-BSI (18.4%), and CA-BSI (10.2%). High Pitt score and inappropriate empirical antibiotic therapy were the independent risk factors for mortality by multivariate analysis. In conclusion, the present data suggest that clinical features, outcome, and microbiologic features of causative pathogens vary by origin of BSI. Especially, HCA-BSI shows unique clinical characteristics, which should be considered a distinct category for more appropriate antibiotic treatment.</P>

Bortezomib is the first clinically available proteasome inhibitor that is clinically effective in the treatment of multiple myeloma. A proteasome inhibitor acts through multiple mechanisms to arrest tumor growth, tumor spread, and angiogenesis. The main adverse effects of bortezomib are gastrointestinal symptoms, cytopenia, fatigue, and peripheral neuropathy. To date, severe paralytic ileus has not been reported as a toxic effect of bortezomib treatment in multiple myeloma. Bortezomib is a novel agent that has only been used clinically for 30 months, so a need exists to further evaluate its toxicity. We report a case of grade Ⅲ (NCI CTCAE v3.0) or grade Ⅳ(SWOG toxicity criteria) paralytic ileus in a 65-year-old man with relapsed multiple myeloma who underwent one cycle of single-agent bortezomib treatment scheduled in a 21-day cycle (1.3 mg/㎥ as a single i.v. bolus on days 1, 4, 8, and 11).

In this study, a daily water balance model for effective rainfall in paddy fields is descrived, and compares the results with field data. The model was used to simulate seasonal effective rainfall for ideal plots with different irrigation scheduling. The followings are a summary of this study results: 1. Effective rainfall during irrigation season of paddy fields in 1985 ranged from 172.3mm at 4cm ridge to 206.7mm at 6cm ridge. They were 63.1% and 75.7% of total precipitation during that span, respectively. The water balance model simulated that 60.5% and 69.5% precipitation may be considered to be effective rainfall. 2. Daily rainfall appears to be important to the ratios of effective rainfall to the total. 3. Measured and estimated effective rainfall had a high correlation. R=0.9805
