연구목적 : 저자들은 태생기 동안에 받는 유전외적 요인, 즉 환경적 요인이 산발성 정신분열병 환자들의 발병에 크게 관여할 것이라고 가정하였다. 이를 검증하기 위하여 형제 중 1인 이상이 발병하여 가족력을 분명히 알 수 있는 정신분열병 환자군(이하 형제 환자군)과 가족력이 없는 산발성 정신분열병 환자군(이하 산발성 환자군) 및 정상대조군을 대상으로 산과적 합병증, 신체미세기형 및 정신분열병의 임상 양상을 비교하였다. 방 법 : 연구 대상은 형제 환자군 43명(남 22명, 여 21명), 산발성 환자군 43명(남 23명, 여 20명), 정상대조군 43명(남 20명, 여 23명)이었다. 산과적 합병증은 Lewis 척도를 이용하여 평가하였고 신체미세기형은 Waldrop 척도를 이용하여 측정하였다. 임상 양상으로서 발병 연령, 병전 기능 수준, 정신병리, 약물에 대한 반응, 회복시의 전반적 기능 수준, 지연성 운동장애의 유무를 평가하였다. 결 과 : 정상대조군과 정신분열병 환자군 전체를 비교하였을 때 산과적 합병증과 신체미세기형의 총점과 각 소항목의 점수에 차이가 없었다. 산발성 환자군과 형제 환자군을 비교하였을 때 산과적 합병증의 전체 점수에서는 유의한 차이가 없었으나, 출생 당시에 태아가 받은 스트레스 항목의 점수가 산발성 환자군에서 유의하게 높았다. 신체미세기형에서는 전체 점수 및 입의 미세기형 점수가 산발성 환자군에서 유의하게 높았다. 신체미세기형의 전체 점수가 4점 이상인 환자수도 산발성 환자군에서 높은 경향성을 보였다. 산과적 합병증과 신체미세기형 사이의 상호 연관성은 찾을 수 없었다. 정신분열병의 임상 양상 중에서는 Krawiecka 척도의 총점 및 양성 증상 점수와 회복시의 전반적 기능 수준만이 형제 환자군에 비해 산발성 환자군에서 유의하게 높았다. 성별에 따라서는 형제 환자군에서 남자 환자의 산과적 합병증이 유의하게 높았다. 결 론 : 본 연구를 통해 산과적 합병증 및 신체미세기형 연구가 정신분열병의 원인을 규명하기 위한 유용한 방법임이 시사되었지만, 가족력, 산과적 합병증 및 신체미세기형의 관련성에 대해서는 분명한 결론을 내리지 못하였다. The authors hypothesized that sporadic schizophrenic patients had more chances of receiving environmental insults during the fetal neural development compared with familial schizophrenics. We tested our hypothesis by comparing obstetric complications(OCs), minor physical anomalies(MPAs) and other clinical features, and examining the correlation between OCs and MPAs in schizophrenic patients who had one or more sibling with schizophrenia(sibling group) and sporadic schizophrenics(sporadic group) and normal controls. OCs were evaluated by the scale of Lewis, and MPAs were measured by the Waldrop scale. There were no significant difference in OCs and MPAs between schizophrenic and control groups. Sporadic group had significantly higher fetal distress, total Waldrop score and Waldrop score for mouth than sibling group. And there was a tendency that the number of subjects having the Waldrop score over 4 points was greater in the sporadic group. No significant correlation was observed between CCs and MPAs. The scores of initial psychopathology and post-treatment functioning were much higher in the sporadic group, but the other clinical feature showed no difference. Although male patients had more OCs than female patients in sibling group, no sex difference were observed as a whole. Our results suggest that, if the methodological weakness were complemented, OCs and MPAs would be useful tools in the search for the cause of schizophrenia.

A primary central nervous system lymphoma(PCNSL) is defined as a lymphoma limited to the cranial-spinal axis without systemic involvement. PCNSLs were formerly very rare, only 0.5∼ 1.2% of all intracranial neoplasms, and were usually associated with acquired immuno-deficiency syndrome(AIDS) and other immune-compromised states. Recently, there has been a clear rise in the incidence of this disease among normal individuals. We describe a 77-year-old female with hyponatremia who presented with a confused mental state. Computed tomography(CT) of the brain demonstrated a suprasellar mass with enhancement. We evaluated the basic hormonal studies and the magnetic resonance imaging(MRI). A ventricular biopsy was done, and the result was a diffuse, large, B-cell-type malignant lymphoma. She presented panhypopituitarism and partial central diabetes insipidus. She received chemotheraphy and was discharged in an improved condition. We report a case of panhypopituitarism due to PCNSL and give a review of the literature.

복잡한 게놈 분석에 용이하도록 효모의 인공 염색체(YAC) 클론닝 시스템은 발달되어왔다. YAC은 박테리아의 인공 염색체(BAC)보다 더 큰 단편을 클론닝할 수 있고, 또한 클론된 단편을 쉽게 변형시킬 수 있다. 형질전환과 연계된 재조합법(Transformation-Associated Recombination; TAR)은 게놈 라이브러리를 만들지 않고 직접 게놈 DNA로부터 분리하고자 하는 유전자나 특정 염색체 부분을 클론닝 할 수 있는 방법이다. 이 방법은 spheroplast transformation을 수행하는 동안, 목적으로 하는 유전자의 5' 그리고 3' 염기 배열(hooks)을 지닌 TAR 벡터와 게놈 DNA 사이에서 일어나는 상동성 재조합에 의해 이루어진다. 효모 내의 in vivo 재조합을 이용한 TAR 클론닝법은 복잡한 게놈으로부터 목적의 염색체 부분을 원형 YAC의 형태로서 선택적으로 분리할 수 있다. 그러므로 TAR 클론닝 법은 특정 염색체로부터 YACs을 만드는데 매우 유용하여, 전체 게놈으로부터 특이적 유전자나 유전자의 family를 분리하는데 효과적인 방법으로 사료된다. Yeast artificial chromosome (YAC) cloning systems have advanced the analysis of complex genomes considerably. They permit the cloning of larger fragments than do bacterial artificial chromosome systems, and the cloned material is more easily modified. Transformation-associated recombination (TAR) is a cloning technique that allows specific chromosomal regions or genes to be isolated directly from genomic DNA without prior construction of a genomic library. This technique involves homologous recombination during spheroplast transformation between genomic DNA and a TAR vector that has 5' and 3' gene targeting sequences (hooks). Using in vivo recombination in yeast, TAR cloning selectively isolates, as circular YACs, desired chromosome segments or entire genes from complex genomes. We propose that TAR cloning can provide an efficient means for generating YACs from specific chromosomes and that TAR cloning may be useful for isolating families of genes and specific genes from total genome DNA.

In the head and neck area, there are so many sensory nerves, which are sometimes injuried iatrogenically or inadvertently so that involved patients complained of the loss of sensations. In such cases, it is important to judge the degree of injuries and regeneration of nerve for better diagnosis and treatment. Seddon and Sunderland's classification, which is commomly used, is focused on histological change and nerve conduction. As times goes by, it is difficult to access patient's sensory disturbance by this method. Until now, so many methods such as contract threshold, direction, two-point discrimination, pin prick, thermal discrimination and current perception threshold have been introduced for sensory evaluation. However, there hasn't been enough information regarding each methodology nor integrated standard methodology for the measurement. the purpose of this study is to get Korean adult normative sensory values of lower lip,chin and tongue using modified methods of contact thershold, ditection, two point discrimination, pin prick, thermal discrimination and assess degree of regeneration of sensory nerve damage.

The surgery of oral and maxillofacial area poses the risk of cranial nerve damage such as trigeminal nerve or facial nerve. Inferior alveolar nerve is prone to damage in the third molar extraction, implant installation, orthognathic surgery, open reduction and rigid fixation, and tumor ablation surgery. On the other hands,facial nerve is likely to be damaged or sacrificed with trauma or parotidectomy. In case of inferior alveolar nerve injury, the incidence is reported to be about 1.3%. The nerve function will almost recover in minimal damage, but it won't recover at last in total damage of a part of nerve unit. In latter cases, nerve regeneration in intended by allograft as nerve substitute or various route of merve condit. But the recovery with autograft is believed to be most relialbe mrthod in the rapair of long-span(longer than 15㎜)nerve defect. We have performed autologous sural nerve graft in the repair of nerve defect, which is caused by resection of benign or malignant tumor. Hereby we report the method of nerve harvesting, recovery of defected peripheral nerve and the complications of donor site with the discussion of sural nerve anatomy.

높은 광흡수 계수를$(1{\times}10^5cm^{-1})$ 가지는 CIGS는 Ga의 비율에 따라서 밴드갭을 조절할 수 있다는 장점을 지니고 있다. CIGS의 밴드갭은 Ga의 비율에 따라 $CuInSe_2$(Eg: 1.0 eV)에서 $CuGaSe_2$(Eg: 1.68 eV)까지의 범위에 존재하며, 태양전지에 서 이상적인 fill factor 모양을 가지도록 Ga의 비율을 높게 조성한다. CIGS 흡수층을 제작하는 방법에는 co-evaporator 방식이 가장 널리 사용되며 연구되고 있다. 이에 본 연구에서는 수평 형태의 hydride vapor transport (HVT)법을 고안하여 CIGS 나노 구조 및 에피성장을 시도하였다. HVT법은 $N_2$ 분위기에서 원료부의 CIGS 혼합물을 HCl과 반응시켜 염화물 기체상태로 변환 후 growth zone까지 이동하여 성장을 하는 방식이다. 성장기판은 c-$Al_2O_3$ 기판과 u-GaN을 사용하였다. 성장 후 field emission scanning electron microscopy(FE-SEM)과 energy dispersive spectrometer(EDS)를 이용하여 관찰하였다. The Cu$(In_{1-x}Ga_x)Se_2$ is the absorber material for thin film solar cell with high absorption coefficient of $1{\times}10^5cm^{-1}$. In the case of CIGS, the movable energy band gap from $CuInSe_2$ (1.00 eV) to $CuGaSe_2$ (1.68 eV) can be acquired while controlling Ga contain ratio. Generally, the co-evaporator method have used for development and fabrication of the CIGS absorption layer. However, this method should need many steps and lengthy deposition time with high temperature. For these reasons, in this paper, a new growth method of CIGS layer was attempted to hydride vapor transport (HVT) method. The CIGS mixed-source material reacted for HCl gas in the source zone was deposited on the substrate after transporting to growth zone. c-plane $Al_2O_3$ and undoped GaN were used as substrates for growth. The characteristics of grown samples were measured from SEM and EDS.

Lactobacillus plantarum HY7712 Ameliorates Cyclophosphamide-Induced Immunosuppression in Mice

( Se Eun Jang ),( Eun Ha Joh ),( Ho Yong Lee ),( Young Tae Ahn ),( Jung Hee Lee ),( Chul Sung Huh ),( Myung Joo Han ),( Dong Hyun Kim ) 한국미생물 · 생명공학회 2013 Journal of microbiology and biotechnology Vol.23 No.3

Lactic acid bacteria (LAB) in fermented foods have attracted considerable attention recently as treatment options for immune diseases, the incidence of which has been increasing worldwide. The ability of 500 strains of LAB, isolated from kimchi, to induce TNF-α production in peritoneal macrophages was investigated. Lactobacillus plantarum HY7712 most strongly induced TNF-α production as well as NF-κB activation. However, HY7712 inhibited NF-κB activation in LPS-stimulated peritoneal macrophages. When HY7712 was orally treated in cyclophosphamide (CP)-immunosuppressed mice for 5 or 15 days, it reversed the body and spleen weights, blood RBC and WBC levels, and splenocyte and bone marrow cells that were reduced by CP. Orally administered HY7712 increased concanavalin A-induced T cell proliferation to 84.5% of the normal group on day 15, although treatment with CP alone markedly reduced it to 53.7% of the normal group. Furthermore, orally administered HY7712 significantly induced the expressions of IL-2 and IFN-γ in ConA-induced splenic cytotoxic T cells of CP-treated mice. Orally administered HY7712 restored the CP-impaired phagocytosis of macrophages in mice. Orally administered HY7712 also restored the cytotoxicity of NK and cytotoxic T cells derived from spleen and bone marrow against YAC-1 in CP-immunosuppressed mice. Based on these findings, orally administered HY7712 may accelerate the recovery of cyclophosphamide-caused immunosuppression, without evident side effects, by immunopotentiating NK and Tc cells, and may provide a mechanistic basis for using HY7712 as an alternative means in lessening chemotherapyinduced immunosuppression in cancer patients.
