연구배경 : 최근 면역기능저하 환자들이 급증하고 있으며 이들에 있어서 새로 발생된 설명이 불가능한 폐침윤은 매우 흔하면서도 환자의 생명을 위협할 수 있는 상황으로 발전할 수 있다. 폐진균증은 이런 임상상에서 폐침윤의 중요한 원인으로 대두되고 있으나 이에 대한 연구가 많지 않아 본 연구를 시행하였다. 방 법 : 1996년 10월부터 1998년 4월까지 삼성서울병원에서 면역기능저하 환자 중 새로운 폐침윤이 있었던 환자로 조직학적으로 폐에서 진균이 증명되었거나 정상적으로 균이 자리지 않는 부위(sterile)에서 시행한 배양검사장 진균이 배양된 환자들을 대상으로 임상적 특정, 방사선학적 소견, 진단적 검사, 치료 및 그 결과에 대해 후향적인 조사를 시행하였다. 결 과 : 총 13명의 환자 (M : F=8 : 5, 연령 중앙값 47세)에서 14예의 폐진균증이 진단되었다. 진단은 asperogillosis가 12예였고 mucormycosis가 2예였다. 혈액암 환자 9명에서 10예, 장기이식 환자에서 4예의 폐진균증이 진단되었다. 3예에서는 진단당시 경험적 amphotericin B를 중앙값 9일(8-21일)간 투여받고 있었다. 혈액암군 10예 중 9예에서 폐침윤 발견당시 백혈구 감소증이 중앙값 16일동안 지속되었으며 발열(9/10), 기침(6/10), 가래(5/10), 호흡곤란(4/10), 흉통 (5/10), 악설음(4/10) 등의 증상과 징후가 흔하게 관찰되었다. 반면에 장기이식환자군에서는 증상 및 징후가 뚜렸하지 않은 경우가 많았다(p<0.05). 단순 흉부촬영상으로 새로운 폐침윤은 단일 혹은 다발성의 결절(6/14)이나 경결(consolidation)(8/14)의 형태로 나타났으며 흉부 단층촬영상에서는 간유리음영(14/14), 흉수(5/14), 동공형성(7/14) 등의 소견이 관찰되었다. 확진한 방법으로는 개흉술이 10예, 비디오 흉강경술이 2예, 경피적침흡인술이 1예, 농양의 농 배양검사가 1예였다. 모든 환자는 amphotericin B(591-2806mg) 투여를 받았으며 1예에서 liposomal amphotericin B, 1예에서 경구 itraconazole로 치료를 부분적으로 시행하였다. Amphotericin B 투여 후 12/14예에서 폐병변의 호전이 관찰되었으며 14예중 4예에서 사망하거나 회복이 불가능한 상태로 퇴원하였다. 결 론 : 혈액암의 치료로 과립구감소증이 있는 환자나 장기이식 환자에서 새로운 폐침윤이 결절이나 경결의 형태로 발현하면, 증상이 미미하거나 경험적 amphotericin B를 투여하고 있더라도 폐진균증을 의심을 해야하며 적극적인 진단과 치료로써 예후를 호전시킬 수 있을 것으로 기대된다.

Background: Dendritic cell (DC)-based vaccines are currently being evaluated as a novel strategy for tumor vaccination and immunotherapy. However, inducing long-term regression in established tumor-implanted mice is difficult. Here, we show that deoxypohophyllotoxin (DPT) induces maturation and activation of bone marrow-derived DCs via Toll-like receptor (TLR) 4 activation of MAPK and NF-${\kappa}B$. Methods: The phenotypic and functional maturation of DPT-treated DCs was assessed by flow cytometric analysis and cytokine production, respectively. DPT-treated DCs was also used for mixed leukocyte reaction to evaluate T cell-priming capacity and for tumor regression against melanoma. Results: DPT promoted the activation of $CD8^+$ T cells and the Th1 immune response by inducing IL-12 production in DCs. In a B16F10 melanoma-implanted mouse model, we demonstrated that DPT-treated DCs (DPT-DCs) enhance immune priming and regression of an established tumor in vivo. Furthermore, migration of DPT-DCs to the draining lymph nodes was induced via CCR7 upregulation. Mice that received DPT-DCs displayed enhanced antitumor therapeutic efficacy, which was associated with increased IFN-${\gamma}$ production and induction of cytotoxic T lymphocyte activity. Conclusion: These findings strongly suggest that the adjuvant effect of DPT in DC vaccination is associated with the polarization of T effector cells toward a Th1 phenotype and provides a potential therapeutic antitumor immunity.

Objective: This study was conducted to evaluate various wheat supplementation levels on growth performance, blood profiles, nutrient digestibility, and pork quality in growing-finishing pigs. Methods: A total of 120 growing pigs ($[Yorkshire{\times}Landrace]{\times}Duroc$), with an average $27.75{\pm}1.319kg$ body weight, were used in growth trial. Pigs were allotted into each treatment by body weight and sex in 4 replicates with 6 pigs per pen in a randomized complete block design. Fourphase feeding programs were used in this experiment. The treatments included the following: i) corn-soybean meal (SBM) - based diet (CON), ii) corn-SBM - based diet+15% of wheat (W15), iii) corn-SBM - based diet+30% of wheat (W30), iv) corn-SBM - based diet+45% of wheat (W45), and 5) corn-SBM-based diet+60% of wheat (W60). Results: There was no significant difference in growth performance among the dietary treatments. However, the gain-to-feed (G:F) ratio tended to increase (quadratic, p<0.08) when the pigs were fed a higher wheat diet during the finishing period. The digestibility of crude ash and fat tended to decrease as the wheat supplementation level increased (p<0.08). The proximate analysis of the longissimus muscle was not affected by the dietary level of wheat. The crude ash content in pork was decreased linearly as the wheat supplementation level increased (p = 0.05). There was no significant difference in the pH level, shear force, water holding capacity, and cooking loss of the pork. In pork and fat, $L^{\star}$, $a^{\star}$, and $b^{\star}$ values were not significantly different among dietary treatments. Conclusion: Wheat can be supplemented up to 60% in a growing-finishing pig without detrimental effects on growth and pork quality. The G:F ratio tended to improve in the finishing period by wheat inclusion.

Four young swamp buffalo cows of similar age ranging in weight between 280 to 380 kg and trained to do physical work were used in a study to determine energy and protein requirements for draught using a $4{\times}4$ Latin square designed experiment. The experiment consisted of field trials employing 4 levels of work load, e.g. no work as control, and loads amounting 450 to 500 Newton (N) pulled continuously for 1, 2 and 3 h daily for 14 consecutive days. Cows were fed king grass (Penisetum purpuroides) ad libitum and were subjected to materials balance trials. Body composition was estimated in vivo by the body density method and daily energy expenditure (EE) was calculated from ME minus retained energy (RE). The results show that EE while not working ($EE_{resting}$) was $0.42kgW^{0.75}MJ/d$ and maintenance ME ($ME_m$) was $0.37kgW^{0.75}MJ/d$. ME requirement increased to 1.65 times maintenance for the work of 3 hours. The energy expended for doing exercise ($E_{exercise}$) was 9.56, 20.0 and 25.86 MJ/cow for treatments 1, 2 and 3 II, respectively. Fat retention was absent in all groups of working cows, but protein retention was only negative for cows undertaking 3 h work. The relationship between $E_{exercise}$ (MJ), work load (F, kN), work duration (t, h) and body mass (W, kg) was found to be: $E_{exercise}=(0.003F^{1.43}t^{0.93})/W^{0.09}MJ$. The maintenance requirement for digestible protein was $2.51kgW^{0.75}g/d$, whereas digestible protein for growth ($DP_{growth}$) and for work ($DP_{work}$) followed the equations: $DP_{growth}=[(258+1.25W^{0.75}){\Delta}Wkg/d]g$ and $DP_{work}=[12.59e^{0.95t}]g$, respectively The coefficients a, b and c for the calculation of $E_{exercise}$ components according to the Lawrence equation were found to be 2.56 J/kgW.m, 5.2 J/kg load carried.m and 0.29, respectively, thus efficiencies to convert ME into work were 0, 16.09, 27.3 and 32.44% for control, 1, 2 and 3 h/d work, respectively. ME and DP requirements for a 250 to 400 kg working buffalo cow allowing to growth up to 0.5 kg/d are presented.

This experiment was conducted to determine the effect of variety and planting year on the nutritive values of corn fed to growing pigs. Four corn varieties examined in this experiment were planted in the same village located in Longhua County, Heibei Province, China, in 2012, 2013, and 2014, respectively. During each year, corn was hand-harvested in early October and sun dried to about 14% moisture content. Three batches of twenty-four barrows ($33.27{\pm}4.30$, $31.88{\pm}2.93$, $34.21{\pm}3.81kg$ body wight [BW] in 2012, 2013, and 2014, respectively) were used and allotted to a complete block design with 4 diets and 6 replicate pigs per diet. Pigs were individually placed in metabolic crates. The four experimental diets were formulated by mixing each variety of corn and vitamins and minerals, respectively. A five-day collection period followed a seven-day diet acclimation period. The results indicated that variety of corn significantly influenced the available energy content (digestible energy [DE] on dry matter basis, p<0.05; metabolizable energy (ME) on dry matter basis, p<0.05, respectively), and the apparent total tract digestibility (ATTD) of organic matter (p<0.01), dry matter (p<0.05), gross energy (p<0.05), neutral detergent fiber (p<0.01), acid detergent fiber and ether extract (p<0.05). The planting year also significantly influenced the available energy contents (DE on dry matter basis, p<0.05; ME on dry matter basis, p<0.01, respectively) and the ATTD of neutral detergent fiber (p<0.01), acid detergent fiber (p<0.01), crude protein (p<0.01), and ether extract (p<0.01). No interaction was observed between the variety and planting year in DE and ME contents in corn. In conclusion, the variety and planting year significantly influenced the available energy and nutrient digestibility of corn fed to growing pigs.

목 적 : 2000년 6월과 7월에 본원 신생아 중환자실에서는 ESBL 생성 K. pneumoniae에 의한 패혈증이 집단 발생하여 전체 환아에 대한 보균 상태를 파악하고 감염관리를 위해 감시배양을 실시하였다. 당시 집단 보균 상태임을 발견하여 보균자에 대한 격리를 실시한 결과 집단보균을 해결할 수 있었으나 대부분의 환아가 보균 상태로 퇴원하였다. ESBL 생성 K. pneumoniae는 대변 내 균이 장착되어서 입원 환아들간에 집단 감염을 일으킬 수 있으며, 이러한 균주에 의한 집단감염은 치료와 예후에 중요한 인자로 작용될 것으로 생각된다. 이에 저자들은 집단보균 발생시 분리된 ESBL 생성 K. pneumoniae의 분자 역학적 특징과 보균환아들의 추적관찰 결과를 알아보고자 본 연구를 시행하였다. 방 법 : 2000년 7월 28일부터 12월 30일까지 입원환아를 대상으로 직장내 도말법으로 감시배양검사를 시행하였다. 감시배양검사는 재원환아들에서 1주 간격으로 시행하였고, 신환은 입원 당일에 시행하였다. 균주의 형별 검사를 위해서 Pulsed-field gel electrophoresis(PFGE)를 시행하였고, 보균 상태로 퇴원했던 환아들은 외래에서 대변 배양검사로 추적 관찰하였다. 결 과 : 감시 배양기간 중 총 80명(28.5%)의 환아에서 보균이 확인되었고, 퇴원시 5명(6.3%)에서 음성이 확인되었다. PFGE를 시행한 65명의 타이핑 결과, 일회의 PFGE를 시행한 53명에서 분리된 균주의 염색체 유전자 분획양상은 집단클론 6가지, 단독클론 10가지형으로 분류되었고, 집단 클론 중 A형이 28명(52.8%)으로 가장 많았고, B형이 11명(20.8%), C, D, F, G형이 각각 1명(1.9%)이었다. 2회 이상 검사를 시행한 12명 중 초기검사에서는 A형이 10명(83.3%)으로 월등히 많았고 B형은 2명(16.7%)이었으며, 추적검사에서 분획 양상이 변화된 경우는 6명(50%)이었고, 이들은 A나 B로 변화된 경우가 각각 2명(33.3%)이었다. 변화되지 않은 6명(50%)은 모두 A형으로 남아 있었다. 월별 PFGE 양상은 처음 배양시 집단클론 A, B, C, D형 4가지와 단독클론 세 가지형이었으나 감염 관리를 하면서 11월부터 집단클론 A, B 두 가지형으로 나타나는 양상을 보였고, A형이 더 우세하였다. 보균된 상태로 퇴원한 75명 중 외래 추적관찰이 가능했던 30명을 대상으로 대변 배양검사를 시행한 결과 모두 음성이 확인되었다. 결 론 : 다양한 클론의 균주에 의한 집단보균 상태는 감염 관리를 하면서 단일 클론으로 변화하는 양상을 보였고, A형이 우세한 것으로 보아 집단 보균을 일으킨 유형 중 주 집단 클론은 A형이었음을 알 수 있었다. ESBL 생성 K. pneumoniae 보균 상태는 중환자실내에 입원기간 중에는 거의 지속되지만, 지역사회로 복귀하면 전부 해제되는 것으로 보인다.
