This study was carried out to determine whether dermal mast cell responses to Parasoninn westemoni in an abnormal host, the mouse, were dependent on the site of metacercarial inoculation. In mice during subcutaneous infection, the number of der- mal mast cells were increased significantly (p<0.05) at the first week ($38.3/\textrm{mm}^2$) and then persisted at a high level until the sixth week ($45.2/\textrm{mm}^2$) of infection compared with PBS- injected (control) mice (range: $19.4-25.1/\textrm{mm}^2$). In mice during oral infection, the number of dermal mast cells were increased significantly (p<0.05) at two weeks ($33.5/\textrm{mm}^2$) after infection and remained at these levels thereafter compared loth non-infected (control) mice (range: $17.4-22.3/\textrm{mm}^2$). In mice both during subcutaneous and oral infection, the recruited dermal mast cells showed extensive degranulation at the second week (68.4%) and 60.7%, respectivelyl, reached a peak at the third week (81.4%, and 92.1%, respectively) and then declined slightly thereafter. By contrast, in both control mice, about 10% of dermal mast cells were degranulated. In conclusion, this study suggests that dermal mast cell responses to p. westemcni in mice are dependent on cutaneous sensitization by larval excretory-secretory antigens, irrespective of infection route.

A 4-year old Korean-native cow of third parturition delivered an deformed calf with congenital anasarca and hypoplasia of the extremity at Muan County in Chonnam Province. At parturition, the dam showed amniotic fluid approximately two times more than that at the normal and also occurred severe dystocia. The anomaly died before parturition was 82 cm long and weighed 25 kg. It was difficult to recognize the neck and face of the anomaly due to severe edema and the stretched tongue through mouth was found. The shape of the extremity was recognizable and the systemic hypoplasia of the body with marked edema was found. At necropsy, there was a large amount of serous fluid both in pleural and peritoneal cavity. Also the fluid was contained some of yellowish granular materials and diffusely was fulfilled in all subcutaneous tissue. There was a partial opening in diaphragm which was resulted in the protrusion of approximately half of liver toward peritoneal cavity. There were two kidneys (15${\times}$21 and 13${\times}$18 cm) on the left which were enlarged and relatively larger than the right one (13${\times}$9 cm). In addition, there were found slight to moderate hepatomegaly and splenomegaly with slight congestion, and diffuse edema of intestinal serosa. Lung (32${\times}$49 mm) with marked hypoplasia was smaller than the size of heart (56${\times}$45mm). Serological test to the dam showed relatively high antibody titer (＞64) to Akabane virus which might be involved in the outbreak of the deformed Korean-native calf as one of many causative agents.

The use of music as a means of inducing positive emotions and subsequent relaxation has been extensively studied by researchers. A great deal of this research has focussed on the use of music as a means of reducing feelings of anxiety and stress as well as aiding in the relief of numerous pathologies. The purpose of this study was to evaluate this effect of music using laser doppler flowmeter that monitors relative changes in the muscular blood cell perfusion, concentration of moving blood cells, mean velocity of the myofascial pain disorder patients. Total of 30 subjects were selected. They were monitored by LDF(Laser Doppler Flowmeter) during music listening for 3 minutes. LDF probe was placed over the temporalis muscle. The obtained results were as follows: 1. The average blood perfusion for 3 minutes of music listening at surface of temporalis muscles were elevated on both affected and unaffected parts compared to rest time. 2. The average of blood perfusion elevated during music listening at surface of temporalis muscles were higher in affected part than unaffected part. 3. Increase of blood perfusion during music listening is proportioin to that before music listening. In summary, these results may encouraging start to the elucidation of the hemodynamic events occuring during music listening and aimed to serve as a base for further studies.

암, 심장병과 더불어 우리나라 3대 사망 원인질환의 하나인 뇌졸중. 단일 질환으로서는 가장 중요한 사망원인 암에도 불구하고 올바른 인식부족으로 돌이킬 수 없는 결과를 초래하기도 하다. 뇌에 혈액을 공급하는 혈관이 막히거나 터져서 뇌의 일부가 망가지는 뇌졸중은 정기적인 운동과 신선한 음식을 섭취하고, 갑작스런 추위에 노출되거나, 심한 스트레스 및 과로를 피하는 것이 최상의 예방책이다.

시장조사기관인 IDC는 2002년께 웹폰이나 디지털TV, 셋탑박스, 디지털 비디오 같은 임베디드 시스템이 PC시장을 앞설 것으로 내다보고있다. 이에 따라 이 시장을 둘러싼 업체들의 경쟁이 치열하게 펼쳐지고 있는데 이러한 임베디드 시스템에 필연적으로 사용되다시피하는 것이 바로 실시간 운영체제(RTOS:Real-Time Operating System)이다. 실시간 운영체계가 가지는 특징, 응용분야, 그리고 인터넷 상에서 실시간 운영체계의 정보를 얻을수 있는 방법에 대해 간략하게 소개하고자 한다.

피임(避妊, Contraception)이란 인위적으로 임신을 피하는 것을 말한다. 임신 가능한 요인을 제거하는 것으로 수정을 예방하거나 수정란이 자궁내막에 착상되지 않도록 조치를 취하는 것이다. 피임을 하는 목적은 인공적으로 출산을 제한하기 위해 임신을 미연에 방지하고자 하는 의도도 있으나, 피치못할 상황에 처해 도의적으로, 혹은 여성의 신체적 건강을 위해서 행하는 인공임신중절을 사전에 예방하는 데도 그 의도가 있다.

Pneumomediastinum and subcutaneous emphysema produced by air turbine dental drills, although widely reported in dental publications, are rarely reported in the thoracic journals. We report a case of 38-year-old man with pneumomediastinum and subcutaneous emphysema after use of a air turbine dental drill for dental extraction.

과거에는 심한 감염을 동반한 족부질환은 한 번 발생하면 절단하는 것이 최선의 치료였다. 특히 발목 이상 대절단의 경우 5년 후 50% 가량에서 나머지 다른 쪽 다리를 절단케 하고 심한 경우 사망에까지 이르러 치료결과가 좋지 않았다. 최근 세브란스 병원 족부클리닉에서 당뇨병성 족부감염환자를 대절단 없이 95%까지 치료하는 성과를 거뒀다. 정형외과 이진우 교수를 만나 인터뷰 해봤다.

최근 알레르기 질환의 빈도가 많이 증가하였고, 그 중 식품알레르기(Food Allergy)는 소아 연령에서 많이 발생하고 있다. 병원에서 진단 후에는 치료 과정 중에서 식품회피(알레르기 유발 식품을 피하는 것)는 필수적이라 성장기의 소아, 청소년에게는 영양적 문제와 성장부진 등 합병증을 유발할 가능성이 있다. 그렇기 때문에 영양적 문제와 성장부진 문제를 예방하기 위해서는 우선, 의사의 정확한 진단이 필수적이다. 그 다음으로 무분별하고 과다한 식품 제한을 막고, 성장 시기에 맞는 영양관리가 필요하다.
