Oxygen deficiency has been frequent in a clouted space. Wood consumes oxygen and discharges carbon dioxide Instead of photosynthesis in closed space without light, so do some microorganisms on the surface. We experienced a case that a healthy Insect-proofer fell down and died of asphyxia on stair-board at 7 m below the hatch of the cargo-hold shipping wood Analysis of gases in cargo-hold revealed O2; 12.3%, CO; 105 ppm, CH4; 2.7%, and H2S; 1.9% at 1 m below the hatch, and then O2; 6.1%, CO; 220 ppm, CH4; 2.9%, and H2S, 2.3 ppm at 2.5 m below the hatch. Autopsy findings were unremarkable. We justiced the cause of death asphyxia due to oxygen deficiency. As seen in this case, the serious oxygen deficiency was accounted for oxygen consumption by wood and microorganisms.

연구목적: 본 연구는 여성노인을 대상으로 저항운동 시 사용되는 set구성 방법에 중 ascending set, descending set, drop set를 각각 적용시켜 Myokine의 변화를 알아보고자 하였다. 연구방법: 연구대상은 노인복지시설을 이용하고 있는 만 65-72세 사이의 여성노인 32명을 대상으로 ascending set, 8명, descending set 8명, drop set 8명, control group 8명으로 구분하였다. 자료처리는 반복측정에 의한 이원변량분석(two-way ANOVA with repeated measure)을 사용하였으며, 유의도는 .05로 하였다. 결론: 운동프로그램은 12주간 주 3회 실시하였으며, 신체구성과 IL-15, BDNF, VEGF, Irisin의 변화를 관찰하였다. 연구결과 신체구성의 체중, 체지방률, 제지방량 모두 유의한 차이가 없었다. IL-15와 BDNF는 운동 전·후의 비교결과 Descending set와 Drop set에서 운동 후 유의하게 증가하였고, 집단 간의 차이에서 Descending set와 Drop set 집단이 대조집단에 비하여 높게 나타났다. VEGF는 운동 전·후의 비교결과 Descending set와 Drop set 집단이 유의하게 증가하였으며, 집단 간의 차이에서 Descending set와 Drop set가 Ascending set와 control group 보다 높게 나타났다. Irisin은 집단 간 차이는 없었지만 Ascending, Descending, Drop set집단에서 운동 전에 비하여 운동 후 유의한 차이로 증가하였다.. Purpose: The purpose of this study is to identify the change of Myokine by applying ascending set, descending set, and drop set which are set composition used during elderly women’s resistance training. Method: 32 participants aged 65 to 72 who were users of welfare facilities for the aged were divided into 4 groups. They were ascending set group of 8, descending set group of 8, drop set group of 8, and control group of 8. The training program was conducted 3 times a week for 12 weeks and the change of body composition, IL-15(interleukin-15), BDNF(brain derived neurotrophic factor), VEGF(Vascular endothelial growth factor) and Irisin was observed. Two-way ANOVA with repeated measure was used for data processing. Result: The result of this study is as follows. Weight, %fat, and LBM(lean body mass) without fat showed no significant change. IL-15 and BDNF increased significantly after training in Descending set group(p<.05; p<.01)and Drop set group(p<.01; p<.05). VEGF significantly increased in descending set group(p<.01) and drop set group(p<.05). Among groups, VEGF was higher in descending set and drop set groups than ascending set and control groups. Irisin showed no difference between groups, but it showed significant increase after training in ascending(p<.05), descending(p<.05), and drop set groups(p<.05).

Park, Dong-Seok,Kim, Ji-Hoon,Min, Byung-Il,Oh, Soo-Myung 경희대학교 동서의학연구소 1999 INTERNATIONAL SYMPOSIUM ON EAST-WEST MEDICINE Vol.1999 No.1

Dong-Seok Park¹, Ji-Hoon Kim¹ and Byung-Il Min, Soo-Myung Oh,³¹Department of Acupuncture and Moxibustion, College of Medicine, ²Department of Physiology, College of Medicine, And ³East-West Medical Research Institute, Kyung Hee University,Seoul, Korea. Analgesic Effect of Manual Acupuncture and Electroacupuncture combined with Twirling Method. Proceeding of International Symposium on East-West Medicine Seoul. 187-200, 1999.-Twirling the needle (TN) is one of several needing methods frequently used for acupuncture in the oriental medicine. The present study was conducted to see if TN enhanced the antinociceptive effect produced by plain-or electroacupuncture in the rat tail flick test. Rats (Sprague-Dawley, 200-300g)lightly anesthetized with thiopental sodium(40mg/kg, i.p.) were used in the tail-flick test. The basal reaction time for tail-flick was 2 sec. For "plain" acupuncture(PA), a needle was inserted for 20 min into a Chock-samni (ST36) acupuncture point which (is located at the anterior tibial muscle and about 10mm below the knee joint). For electroacupuncture(EA), train-pulses(3 Hz,0.3-ms pulse width, 0.2-0.3mA) were applied to the inserted needle for the period of insertion. For combining TN with either PA or EA, TN was performed during the each acupuncture period. Two methods for TN were used; twirling 3 times for 1 second persisted for 1 min in every 5 mins(long-duration and long-interval;LDLI) and twirling 3 times for 1 second persisted for 10 sec in every 1 min(short-duration and short-interval;SDSI). PA and EA produced an increase in tail flick latency (TFL); peak increases were 21.3±5.1% and 42.1±17.3% of the pre-acupunture control, respectively, and occurred immediately after cessation of 20min-acupuncture. Performing TN combined with PA increased TFL more than PA itself by showing a greater peak increase in TFL when performed with a SDSI-TN than with a LDLI-TN(60.6±12.5% and 42.7±22.7% of the pre-acupuncture control, respectively). Performing TN combined with EA also increased TFL more than EA itself and a greater peak increase in TFL was observed with a SDSI-TN as compared to a LDLI-TN(77.5±13.8% and 67.3±14.0% of the pre-acupuncture control, respectively). These results indicate that TN enhances both PA-and EA-produced antinociception where an greater enhanced antinociception than a LDLI-TN. It is suggested that performing a SDSI-TN combined with EA seems to be one of the most effective ways to produce analgesia.

Apoptotic Effect of Co-treatment with Chios Gum Mastic and HS-1200 on G361 Human Melanoma Cell Line

Young-Joo Hur,Young-Ki Kim,Hyun-Ho Kwak,Gyoo-Cheon Kim,Seung-Eun Lee,In-Ryoung Kim,Chul-Hoon Kim1,Bong-Soo Park 대한해부학회 2009 Anatomy & Cell Biology Vol.42 No.2

Chios gum mastic (CGM) is a resinous exudate obtained from the stem and the main leaves of Pistacia lenticulus tree native to Mediterranean areas. Recently it reported that CGM induce apoptosis in a few cancer cells in vitro. Bile acids and their synthetic derivatives induced apoptosis in various kinds of cancer cells and anticancer effects. It has been reported that the synthetic chenodeoxycholic acid (CDCA) derivatives showed apoptosis-inducing activity on various cancer cells in vitro. This study was undertaken to investigate the synergistic apoptotic effect of cotreatment with a natural product, CGM and a CDCA derivative, HS-1200 on G361 human melanoma cells. To investigate whether the co-treatment of CGM and HS-1200 compared with each single treatment efficiently reduced the viability of G361 cells, MTT assay was conducted. To investigate augmentation of apoptosis in G631 cells co-treated with CGM and HS-1200, DNA electrophoresis, Hoechst staining, proteasome activity assay, flow cytometry, Westen blot analyses, immunofluorescent staining and confocal microscopy were performed. In this study, G361 cells co-treated with CGM and HS-1200 showed several lines of apoptotic manifestation such as nuclear condensations, DNA fragmentation, the reduction of MMP and proteasome activity, the decrease of DNA content, the release of cytochrome c into cytosol, the translocation of AIF and DFF40 (CAD) onto nuclei, activation of caspase-9, caspase-3, PARP and DFF45 (ICAD), and up-regulation of Bax whereas each single treated G361 cells did not. Although the single treatment of 40 μg/mL CGM or 25 μM HS-1200 for 24 hrs did not induce apoptosis, the co-treatment of them induced prominently apoptosis. Therefore, combination therapy of CGM and HS-1200 could be considered, in the future, as an alternative therapeutic strategy for human melanoma.

항응고제 치료의 주된 합병증은 출혈로서 주로 뇌실질과 복강 내에 발생하며 사지 근육에 발생하는 근육내 혈종은 매우 드문 것으로 알려져 있다. 이러한 항응고제 치료 후 발생하는 자발성 근육내 혈종은 발생빈도가 드물 뿐 아니라, 심부정맥혈전증과 그 증상이 유사하여 감별하기가 쉽지 않다. 저자들은 항응고제 치료 후 운동 마비가 발생한 사지 근육에서 자발성 근육내 혈종이 발생한 증례를 경험하여 이를 보고한다. Spontaneous intramuscular hematoma(SIH) is an uncommon but serious bleeding complication of anticoagulation therapy that has received little attention. We present a patient of spontaneous muscular hematoma during anticoagulation therapy for acute stroke management. A-74-year old man was admitted with sudden onset of dysarthria and left hemiparesis. Brain MRI and MRA showed acute cerebral infarction along right middle cerebral artery territory and severe stenosis of right proximal cervical internal carotid artery. During intravenous heparin treatment, he complained acute pain and swelling on left leg. Muscular CT showed enhancing focal soft tissue mass on left gastrocnemius muscle and ultrasonography demonstrated multiple hematomas on left gastrocnemius muscle. Treatment of heparin was stopped immediately. After conservative management for hematomas, symptoms were subsided.

The exsiting CHMM is hard to express time-transient-variation. To solve such problem, we proposed a new method that is the hybrid network of the feed-forward networks and the HMM. The network is trained to predict the feature vector, varies in each time, is used instead of the mean vector in the HMM, Hence the dynamic feature of speech pattern is provided for the HMM. At the experiment, we compared the result of CHMM+MCEP, CHMM+MIX with NNPHMM. At the result, we got the recognition rates of 73.8% for NNPHMM.

This study was intended to raise solids yield in the sea tangle extract. Sea tangle extracted by additions of acetone, methyl alcohol, isopropyl alcohol and ethyl alcohol. Among four solvents used for sea tangle extraction, the optimal solvent was ethyl alcohol. The most appropriate method of sea tangle extraction was two-stage extraction, that extracted with addition of ethyl alcohol and residue was extracted with water(1:13, w/v). As the optimal conditions of ethyl alcohol were 25℃ and 70%, respectively. The basis of solids yield in sea tangle extract, optimal extracting time was about 1 hour. The yield of soluble solids under above-mentioned conditions was 18.2%. Drinking product was made by adding 0.1% citric acid, 2% sorbitol and 2% oligosaccharide to the sea tangle extract(Brix 10).
