<P><B>Abstract</B></P><P>Unregulated activation of microglia is a key risk factor contributes to neurodegenerative diseases and suppression of this phenomenon is considered as a potential therapeutic target. The compound isolated from sea horse <I>Hippocampus kuda</I> Bleeler; 1-(5-bromo-2-hydroxy-4-methoxyphenyl)ethanone [SE1] was characterized for its ability in suppressing LPS mediated activation of murine BV-2 cells. Despite the presence of various active molecular groups in the structure, SE1 has not well explored for its biological activities. The outcome of this study clearly indicated that SE1 inhibited the production of inflammatory mediators; nitric oxide, prostaglandin E<SUB>2</SUB> and pro-inflammatory cytokines. Furthermore, it inhibited the protein and gene expression levels of inducible nitric oxide synthase, cyclooxygenase-2, tumor necrosis factor-α, interleukin-1β and interleukin-6. The responsible signaling mechanisms leading to these inhibitions were identified as SE1 mediated blocking of phosphorylation of mitogen activate protein kinase (MAPK) molecules; C-jun-N-terminal kinase (JNK), p38 and nuclear translocation of nuclear factor-κB (NF-κB) p65 and p50 subunits. These results suggest that SE1 has the potential to be further developed as therapeutic against neuro-inflammation.</P> <P><B>Graphical abstract</B></P><P><ce:figure id='f0045'></ce:figure></P>

This study was conducted to investigate the preventingeffects of OPB (Rehmannia glutinosa Libosch and Eleuth-erococcus senticosus Max extracts) and combined OPB/Calcium therapy on bone loss in ovariectomized rats. SixtySprague Dawley rats of 12-week-old were divided into eightgroups: OVX (ovariectomized), OPBL (OPB 50mg/kg),OPBM (OPB100mg/kg), OPBH (OPB 200mg/kg), OPBL/CAL(OPBL+CAL), OPBM/CAL (OPBM+CAL), OPBH/CAL (OPBH+CAL) and CAL (Calcium citrate 88.33mg/kg+1α, 25-dihydroxy-vitamin D3 33.33IU/kg). Bone mineraldensity (BMD), bone mineral content (BMC), bone strengthindices and cortical thickness were analyzed by peripheralquantitative computerized tomography (pQCT). pQCTscanning showed that OVX induced a significant decreasein trabecular bone mineral density and bone mineralcontent in the proximal tibia (-36.4±2.4%, -21.8±12.7%).These decreases were significantly prevented by theadministration of OPBM and OPBM/CAL. Cortical BMDand BMC of tibia were slightly enhanced by OPB and OPB/CAL. However there was no significant difference betweenOVX and OPB, OPB/CAL treated group. Bone strengthindices and cortical thickness were not significantly different.Our results suggest that OPB and combined OPB/Calciumtherapy are effective in preventing the development of boneloss induced by ovariectomy in rats.

The neodymium:yttrium-aluminum-garnet (Nd:YAG) laser is most widely used for treatment of lesions affecting the oral mucosa. A pulsed Nd:YAG laser (SDL-300EN, Samsung Electronics, Korea) with a wavelength of 1.32㎛ was used. In all cases, contact mode was used. Four cases of soft tissue oral lesions are presented to document the clinical aspects. Surgery proceeded without complication and healing was uneventful. This study indicate that the Nd:YAG laser can be used successfully for intraoral soft tissue applications are well tolerated and minimal bleeding.
Lidocaine으로 Retrobulbar block時 發生한 過敏反應 1例
金世煥,朴辰雄,金炳權 대한마취과학회 1977 Korean Journal of Anesthesiology Vol.10 No.3
This report shows a fatal hyperergy occurring during retrobulbar block using lidocaine on a 42 years old male patient. When we injected 60㎎ of lidocaine into the retrobulbar space, following signs were noticed in one minute: hypertension, convulsion, dyspnea and loss of consciousness. In addition to the above symptoms, cardiac arrest developed in 2∼3 minutes and did not respond to any resuscitative effort. It is considered that 60㎎ of lidocaine for retrobulbar block can induce hyperergy and cardiac arrest. The clinical picture and treatment of such reaction is discussed with particular attention to the importance of close observation of all anesthetic patients whether under general or local anesthesia.

A 29 year old female patient came with grade NYHA Fc IV dyspnea of 1 month. No abnormality was heard during auscultation. Arterial blood gas analysis done due to shortness of breath showed a decreased PO_(2) of 64.6 mmHg. Computerized tomography(CT) was checked due to multiple nodules seen in both lower lung fields of the chest X-ray. CT revealed multiple pulmonary arteriovenous malformations in both the mid and lower lung fields. Dyspnea was uncorrected by the application of oxygen. Coil embolization showed improvement of PO2 and dyspnea. The CT follow up at 9 months after the procedure showed no progression of the arteriovenous malformation without any additional symptoms nor dyspnea.

차세대 통신 시스템에서 공통적으로 요구하는 소형화, 광대역화, 집적화추세에 따라 RF소자는 광대역화, 소형화, 집적화를 향해 발전하고 있으며 안테나 기술도 현재 추세에 발맞추어 소형화, 능동집적화, 광대역화를 통하여 개발 방향을 모색하고 있다. 본고에서는 현재 추세인 소형 안테나, 능동 안테나와 더불어 최근 관심이 집중되고 있는 임펄스 통신에 이용될 수 있는 초광대역 안테나 기술에 대해 소개한다. The technical trends of the next generation wireless communication are miniaturization, broad-band operation, and integration. Thus, in accordance with this trend, RF devices and components are being developed in such way, and same with the antenna. In this paper, technology of small antenna, active antenna, and ultra wideband antenna, which can be applied to impulse communication system, are introduced.

Scrub typhus is a potentially fatal infectious disease caused by the organism Orientia tsutsugamushi. Clinical manifestations are fever, skin rash, eschar and varying degree of respiratory distress. The pleural effusion in scrub typhus is rare and secondary to the destruction of vascular endothelium. Because the respiratory symptoms are generally mild and the pleural effusion in scmb typhus is rare than in interstitial pneumonia, there are few comments about the characteristics of scmb typhus with pleural effusion. So we made the comparative study of scmb typhus patients between with pleural effusion and without pleural effusion. 연구배경 치명적일 수 있는 감염질환 중 하나인 쯔쯔가무시중(Scrub typhus)에서 드문 흉막삼출을 동반한 환자에 대한 고찰은 다른 문헌에서도 자주 언급되지 않았다. 따라서 본 저자들은 흉막삼출이 있는 경우와 없는 경우에 따른 쯔쯔가무시중 환자들을 비교하고자 하였다. 방법 2003년에서 2006년까지 조선대학교 병원 내과에 입원중인 환자 중 쯔쯔가무시중 진단을 받은 총 109명의 환자를 대상으로 하여 흉부 X선 검사 및 혈청학적 검사(CPK, LDH, ESR, CRP, AST, ALT, ADA), 혈액학적 검사(WBC, PLT) 및 백분율 검사등을 실시하였다. 결과 흉막삼출이 있는 환자들의 경우 흉막 삼출이 없는 환자들에 비해 ESR 수치가 통계학적으로 의의있게 높았다(p-vaule < 0.05). 결론 흉막삼출 유무에 따른 쯔쯔가무시중 환자간의 비교에 있어 ESR 수치가 통계학적인 의의를 가졌다.
