<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>

『傷寒論』과 『金匱要略』은 仲景의 著述로서 醫方之祖 인정되어 왔지만, 두 책의 관계에 대해서는 오랫동안 논란이 있어 왔다. 그러나 『金匱要略』과 『傷寒論』의 相似條文은 각 책의 108%, 11%를 차지할 만큼 많이 있으며 각 조문을 분석한 결과 높은 상동성을 가지는 조문이 전체의 63.9%를 차지하고 있는데, 이것은 두 책이 서로 동일한 근원에서 나왔음을 보여준다. 따라서 『傷寒論』과 『금궤요략』의 관계를 이해함에 있어서 이들 相似條文에 대한 인식이 반드시 선행되어야 할 것으로 생각된다. Shanghanlun and Jinguiyaolue has the analogous text by the rate of 10.8% and 11.3% respectively. And We have found that 63.9% of them are very similar by the analysis on the analogous text. It is supposed that the Books are originated by same source. So we suggest that the analogous text is very important to understand the relationship of the Books.

지금까지 인터넷에서 단말기의 이동성을 보장하기 위한 연구 방향은 계층적 망 구조에 따라 매크로 이동성과 마이크로 이동성을 분리하는 것이다. 핸드오프가 적은 매크로 이동성의 경우 Mobile IP로 수렴되는 반면 이동성이 잦은 마이크로 이동성의 경우 HA로 보내지는 제어 메시지를 어떻게 줄일 것인가에 대하여 서로 다른 방안이 제시되고 있다. 현재까지 제시된 연구의 공통적인 문제는 게이트웨이 라우터의 집중화로 발생할 수 있는 부하이다. 본 논문에서는 단말기의 이동의 지역성 및 분산된 지역 에이전트 개념을 도입하여 이러한 문제를 개선한 분산 지역 기반 이동 프로토콜인 DRMIP를 제안한다. 또 DRMIP의 특성 및 적용성을 검증하기 위하여 인터넷 프로토콜과의 호환성, QoS 지원성, 시스템 안정성, 광역단위로의 확장성 등의 측면에서 타 프로토콜과 비교 분석하였다.

「금궤요약」은 韓醫學 最高의 雜病專門書로서 그 중요성이 널리 인정되고 있지만, 우리나라에서는 그에 대한 註解나 연구가 미흡한 실정이다. 따라서 著者는 앞으로의 硏究와 敎育의 基本資料로 삼기 위하여 本書의 重要 註繹書에 대하여 정리하였다. 「금궤요약」에 대한 최초의 注繹은 元明間趙良仁의 「금궤요약연의」「개정금궤요약주」等이 유명하다. 日本에서는 「금궤요약주해」을 효시로 「금궤요약방론친주」, 「良沙正經證匯」, 「금궤요약집성」, 「금궤요약집의」, 「금궤옥함요약술의」등의 注本이 있다. Jinguiyuolue(금궤요약), written by Zhong-Jing Zhang(張仲景) in late Han(漢) Dynasty, is very foundamental Cannon of Oriental Medicine. Many Doctors commented on the book from Yuan(元) Dynasty ir! Chian and from Edo(江戶) Period in Japan, but there are a few studies in Korea. So we studied on the commentaries of the book, which published in the three countries, for improving research and education of it in our country.

Background & Object : Dyspepsia for which no organic causes are disclosed is referred to as functional dyspepsia. Functional dyspepsia is here studied in connection with a biopsychosocial model. From the aspect of individual response to external environment, in connection with stress response, functional dyspepsia is studied by both the psychology department and the internal medicine departments. The disease is taken as approachable from the aspect of internal injury due to seven emotions and stress as differentiated by Oriental medicine. Materials and Methods : Targeted at 223 patients underwent medical checks and endoscopy at Kangnam Korean Hospital, Kyunghee University. They agreed to join this clinical experiment. Stress response inventory, GARS (global assessment of recent stress scale), GSRS (gastrointestinal symptom rating scale), diagnostic scores for Ki-depression, and Spleen Disease Differentiation of Syndromes were all measured and evaluated. The test group was comprised of functional dyspepsia patients. The control group was comprised of nonsymptomatic chronic gastritis patients who were found to suffer from chronical gastritis in endoscopy and thus could be diagnosed with functional dyspepsia if symptoms would arise, but did not complain of subjective symptoms. Results showed these corelations: Functional dyspepsia patients were found to have more serious Ki-depression compared to nonsymptomatic chronic gastritis patients. The more serious Ki-depression the more serious the dyspepsia symptoms. The higher the stress response inventory the more serious the dyspepsia. Deficiency of spleen Eum, and Deficiency and Sinking of spleen Gi were found to coincide with serious Ki-depression.

Yookmijihwangtang has been widely used oriental herb prescriptions, which is healing some discuss that come from insufficiency of innate essence and deficiency of kidey Ki. the meaning of healing discusses tonification of insufficient innate essence and insufficient kidney Ki can be regarded as reinforcement of wholely power of keeping homeostasis, that is correlated with immuno-responsibility which protects subject from outer antigen to keep normal vital condition. This study was aimed to investigate correlative effects of Yookmijihw angtang water abstract on the RBC, WBC, blood CD4+ Theler cell count, blood testosterone, blood cAMP and blood cortisol. 40 Sprague-Dawley male rats were divided into 5 groups(Normal, Control, SampleⅠ, SampleⅡ, SampleⅢ), 6 animals in every group. Normal group was not treated anything, control group was administrated normal saline in the same desage of sample Ⅰ. 3 Sample groups were received some of Yookmijihwangrang water abstract at one time per 24 hours during 5 days in different dosage. Sample Ⅰ (1/3 10pack/ml), SampleⅡ (1/62pack/ml), SampleⅢ(1/2.4pack/ml). After finishing treatment, all experimental svbjects were killed for blood sample on RBC, WBC, blood CD4+ T helper cell count, spleen CD4+ T helper cell count, axillary lymph node CD4+ T helper cell count. .blood cAMP, blood testosterone and blood cortisol. The results were as follows: RBC and WBC were incrased in all sample groups. Blood CD4+ Thelper cell count(CD4+ T cell count in the blood/whole lymphocyte count in the blood ×100%) was Mormal 46.17±5.88. Control 44.50±4.37, Sample Ⅰ 53.00±2.28. Sample Ⅱ 53.83±3.87, SampleⅢ 52.17±2.93. By the 95% Duncan ANOVA all experimental groups(sampleⅠ, sampleⅡ, sampleⅢ) showed slight significant difference from Nornal and Control. Blood cAMP(nmd/l) were Normal 1.12±0.17, Control 1.16±0.32, SampleⅠ 0.46±0.07, SampleⅡ 0.44±0.04, SampleⅢ 0.54±0.04 All cxperimental groups were signigicantly different from both Normal and Control groups(p<0.05). Blood cortisol(m l/ml) were Normal 100.00±2.00, Control 90.00±4.00, Samplc Ⅰ 440.00±5.00, SampleⅡ 520.00±40.00, SampleⅢ 470 00±7.00, Blood cortisol of all experimental groups were signifieantly increased(p<0.05). The results suggest that Yookmijihwangiang water abstract could be administrated to patienrts who have some diseases insufficient essence.

We report a case of microcystic meningioma which showed unusual radiological findings resembling malignant tumor. A 44-year-old woman presented with generalized tonic clonic seizure and right hemiparesis. Computed tomography and magnetic resonance images showed a mass at left frontal, parasagittal area with septa-like enhancement and surrounding edema. 201Tl SPECT showed focal uptake in mass lesion which suggests the malignant tumor. The histopathological findings of this tumor revealed to be a microcystic meningioma and Ki-67 labeling index was 3.8. Although the mass was a subtype of meningioma, it showed a early recurrence 10 months after grossly total resection because of high proliferative index. We suggest that the biological behaviour in addition to morphologic classification should be considered in the management of benign brain tumor, such as meningioma.

Gintonin facilitates catecholamine secretion from the perfused adrenal medulla

Na, Seung-Yeol,Kim, Ki-Hwan,Choi, Mi-Sung,Ha, Kang-Su,Lim, Dong-Yoon The Korean Society of Pharmacology 2016 The Korean Journal of Physiology & Pharmacology Vol.20 No.6

The present study was designed to investigate the characteristics of gintonin, one of components isolated from Korean Ginseng on secretion of catecholamines (CA) from the isolated perfused model of rat adrenal gland and to clarify its mechanism of action. Gintonin (1 to $30{\mu}g/ml$), perfused into an adrenal vein, markedly increased the CA secretion from the perfused rat adrenal medulla in a dose-dependent fashion. The gintonin-evoked CA secretion was greatly inhibited in the presence of chlorisondamine ($1{\mu}M$, an autonomic ganglionic bloker), pirenzepine ($2{\mu}M$, a muscarinic $M_1$ receptor antagonist), Ki14625 ($10{\mu}M$, an $LPA_{1/3}$ receptor antagonist), amiloride (1 mM, an inhibitor of $Na^+/Ca^{2+}$ exchanger), a nicardipine ($1{\mu}M$, a voltage-dependent $Ca^{2+}$ channel blocker), TMB-8 ($1{\mu}M$, an intracellular $Ca^{2+}$ antagonist), and perfusion of $Ca^{2+}$-free Krebs solution with 5mM EGTA (a $Ca^{2+}$chelater), while was not affected by sodium nitroprusside ($100{\mu}M$, a nitrosovasodialtor). Interestingly, LPA ($0.3{\sim}3{\mu}M$, an LPA receptor agonist) also dose-dependently enhanced the CA secretion from the adrenal medulla, but this facilitatory effect of LPA was greatly inhibited in the presence of Ki 14625 ($10{\mu}M$). Moreover, acetylcholine (AC)-evoked CA secretion was greatly potentiated during the perfusion of gintonin ($3{\mu}g/ml$). Taken together, these results demonstrate the first evidence that gintonin increases the CA secretion from the perfused rat adrenal medulla in a dose-dependent fashion. This facilitatory effect of gintonin seems to be associated with activation of LPA- and cholinergic-receptors, which are relevant to the cytoplasmic $Ca^{2+}$ increase by stimulation of the $Ca^{2+}$ influx as well as by the inhibition of $Ca^{2+}$ uptake into the cytoplasmic $Ca^{2+}$ stores, without the increased nitric oxide (NO). Based on these results, it is thought that gintonin, one of ginseng components, can elevate the CA secretion from adrenal medulla by regulating the $Ca^{2+}$ mobilization for exocytosis, suggesting facilitation of cardiovascular system. Also, these findings show that gintonin might be at least one of ginseng-induced hypertensive components.

Earthworm extract has shown anticancer characteristics. In the present study, we examined the effect of chronic treatment with a high dose of earthworm (Eisenia andrei) extract (EE) on cell proliferation and neuroblast differentiation in the hippocampal dentate gyrus (DG) of 3-week-old mice using 5-bromo-2’-deoxyuridine (BrdU) and Ki-67 immunohistochemistry for cell proliferation and doublecortin (DCX) immunohistochemistry for neuroblast differentiation, respectively. BrdU-, Ki-67-, and DCX-immunoreactive cells were easily detected in the subgranular zone of the DG in vehicle (saline)-treated mice. However, BrdU-, Ki-67-, and DCX-immunoreactive cells in the 500 ㎎/㎏ EE-treated mice decreased distinctively compared to those in the vehicle-treated mice. In addition, brain-derived neurotrophic factor (BDNF) immunoreactivity and its protein level decreased markedly in the DG of the EE-treated group compared to those in the vehicle-treated group. These results indicate that chronic treatment with high dose EE decreased cell proliferation and neuroblast differentiation, and that BDNF immunoreactivity decreased in the DG of EE-treated mice.
