The β₃-adrenergic receptor is expressed in visceral adipose tissue in humans and is thought to contribute to the regulation of the resting metabolic rate and lipolysis. We studied the influence of a mutation in the β₃ -adrenergic receptor gene(Trp64Arg) on body fat distribution, central obesity, lipid metabolism in 65 healthy young male adults. One out of 65 subjects were homozygous (Arg/Arg) for the trp64Arg mutation, 17 subjects were heterozygous (Trp/Arg), and 47 lacked the mutation(Trp/Trp). The body weight, height, body mass index, waist-to-hip ratio were similar between the subjects with- and without the mutation. Total body fat, abdominal fat amount, body fat distribution, serum total- and HDL-cholesterol, triglyceride, glucose, and insulin concentrations were also not different according to the presence or absence of the mutation. These results suggested that Trp64Arg mutation in β₃-adrenergic receptor gene is not a major contributing factor for central obesity or change in lipid metabolism in Korean young adults.

We present a series of 42 patients with the lateral ventricular mass lesions who underwent operative removal between 1979 and 1992 at the Seoul National University Hospital. These lesions included 29 tumors, 10 benign cysts and 3 arteriovenous malformations. There were 20 lesions in the trigone, 14 in the frontal horn, 6 in the body, and 2 in the temporal horn. Together with the age of the patient, the location in the lateral ventricle and the CT or MR patterns, the range of the differential diagnosis of the lesions can be narrowed. The mass were removed by various surgical approaches ; 11 by the middle frontal gyrus, 10 by the superior parieto-occipital, 13 by the middle temporal gyrus, 4 by the anterior transcallosal, 2 by the posterior transcallosal and 3 by the combined approaches. The superior parieto-occipital approach left postoperative morbidities in 64% and other approaches in 20 to 25% of the cases. These morbidities included hemiparesis, hemianopsia, aphasia, memory distubance and seizure. Most hydrocephalus disappeared without the shunting procedure after removal of the lateral ventricular mass. The high frequency of postoperative complications in the superior parieto-occpital approach require meticulous consideration in the selection of this approach.

Background: Micafungin, a potent inhibitor of 1,3-β-D-glucan synthase, is a novel antifungal agent of the echinocandin class. In vitro study showed that micafungin was effective against Aspergillus species as well as Candida species, but clinical data on the prophylactic efficacy against invasive fungal infections (IFIs) other than candidiasis are still lacking. Materials and Methods: We identified 60 consecutive adult hematopoietic stem cell transplantation (HSCT) recipients who received at least 3 doses of micafungin during neutropenic period. Micafungin was started as an alternative in patients who were intolerant or had adverse events (AEs) to primary prophylactic antifungal agents. We retrospectively reviewed the medical records and analyzed the efficacy and safety of micafungin for prophylaxis against IFIs. Results: The patients either had autologous (n=9) or allogeneic (n=51: 1 syngeneic, 24 sibling, 26 unrelated donor) HSCT. Itraconazole oral solution (n=58) was the most frequently used first line antifungal agent for prophylaxis and was administered for median 11 days. The most frequent cause of switch to micafungin was vomiting (n=42). The duration of neutropenia and micafungin administration was median 13 and 12 days, respectively. A successful outcome was achieved in 45 (75%) patients. Empirical antifungal therapy was initiated in 13 (22%) patients. There were 2 cases (3.3%) of breakthrough fungal infections which comprised a probable invasive pulmonary aspergillosis and a possible invasive fungal sinusitis. There was no case of invasive candidiasis. A total of 53 (88%) patients experienced at least one AE regardless of causality during micafungin administration. The most frequent AEs were hypokalemia, vomiting, diarrhea, and elevated serum aspartate aminotransferase or alanine aminotransferase. Among the aforementioned AEs, only 1 case of diarrhea could be classified as a probable relation with micafungin when causality was assessed. There was no AEs that caused discontinuation of micafungin. Conclusions: Micafungin seems to be a safe and effective agent for prophylaxis of IFIs including aspergillosis as well as candidiasis in HSCT recipients. However, further large, prospective, and randomized comparative studies are warranted for aspergillosis.

목적: 비혈연간 골수이식은 혈연내에 적절한 골수공여자가 없는 만성골수성백혈병, 고위험군의 급성별혁병, 면역억제치료에 실패한 재생불량성빈혈 및 각종 난치성 조혈모세포질환의 완치를 위한 표준적인 치료방법으로 정착되고 있다. 혈연간 표준적인 동종 이식에 비하여 비혈연간 이식시에는 생착부전, 이식편대숙주반응과 감염이 더 빈번하게 발생하며, 국내에서는 아직까지 체계적인 임상연구결과가 보고된 바 없었다. 이에 본 센터에서는 1995년 10월 이후로 약 20개월간 26예의 비혈연간 골수이식을 시행하였으며 3개월 이상의 추적관찰이 가능하여 이식초기 합병증의 관찰 및 분석이 가능하였던 20예의 환자를 대상으로 이식성적 및 문제점을 보고함으로써 새롭게 확대되고 있는 이 분야의 임상연구 및 진료의 활성화를 꾀하고자 한다. 방법: 각종 혈액 종양질환으로 비혈연간 이식을 시행한 총 26예의 환자중 3개월이상의 추적관찰이 가능하였던 20예를 대상으로 후향적으로 임상경과를 분석한 후 생존 분석을 시행하였고, 환자의 연령, 성별, 질병의 상태, 조식 적합 항원의 일치정도, 이식편대 숙주 반응의 유무와 생존기간과의 상관관계를 살펴보았다. 또한 표준위험군과 고위험군으로 나누어 생존율을 비교하였고 이식과 관계된 생착 부전, 이식편대숙주반응, 감염의 발생과 양상 그리고 그 합병증을 관찰하였다. 결과: 1. 환자와 공여자간에 HLA 불일치가 20예 중 4예에서 있었으며, 생착여부의 확인이 가능했던 17예 중 16예에서 생착이 확인되어 94.1%의 생착율을 보였다. 2. 급성이식편대숙주반응은 62.5%(10/16예)에서 발생하였으며 111도 이상의 급성의 이식편대숙주 반응은 25%(4/16예)에서 발생하였다. 만성이식편대숙주반응은 40%(2/5예)의 환자에서 발생하였으며 이들 모두 국소형으로 중증의 진행형 만성이식편대숙주반응이 관찰된 환자는 없었다. 3. 호흡기 합병증은 10예(50%)에서 발생하였으며 감염성 폐렴을 포함한 호흡기 합병증이 가장 흔한 일차적인 사망 원인이었다. 호흡기 합병증이 발생했던 10예중 6예가 감염에 의한 폐렴이 의심되었고 나머지 4예는 특발성 간질성 폐렴이었다. 4. 8.5개월의 중앙추적기간 중 35%의 생존율을 관찰할 수 있었고, 생존기간은0.5개월에서 15개월 (중앙치:4개월)이었다. 한편 고위험군은 25%(3/12예), 표준위험군은 50%(4/8)의 생존율을 관찰할 수 있었다. 5. 가장 흔한 사망 원인은 감염성 폐렴을 포함한 호흡기 합병증(6예)이었고, 이외의 사망 원인으로는 급성 이식편대숙주반응과 다장기부전이 각각 2예, 생착 부전, 간정맥 폐쇄, 그리고 재발이 각각 1예였다. Unrelated bone marrow transplantation(UBMT) has been increasingly recognized as the standard treatment for cure of chronic myelogenous leukemia, high risk acute leukemia, aplastic failed on immunotherapy, and the variety of refractory hematologic diseases in patients lacking a related donor. However, as compared to HLA identical sibing transplantation, UBMT carries higher incidence of graft failure, graft versus host disease(GVHD), and infection. In our center, 26 patients underwent UMBT between October 1995 and June 1997. The minimum follow-up of 3 months was possible in 20 patients, for whom early complications and clinical outcomes were assessed. The median age of the 20 patients was 24 years. 8 patients had standard risk disease and 12 patients had high risk disease. All patients received various preparative regimens including total body irradiation according to disease and disease status. 19 patients received CsA + short course MTX for GVHD prophylaxis. One patient received marrow that was depleted of T cells ex vivo using avidinbiotin column. The class I loci were typed by serological methods and HLA-A, HLA-B and HLA-DRB1. 3 additional pairs were one minor mismatched at the HLA-B locus. Another one patients was one major mismatched at the DRBI alleles. 17 patients were evaluable for engraftment. Successful enfraftment was confirmed in 16 patients(94.1%). Only one patient who was performed one major DRBI mismatched transplants experienced graft rejection. 16 patients were evaluable for acute GVHD. The overall incidence of acute GVHD developed in 4 patients(25%). Five patients were evaluable for the development of Ⅳ acute GVHD developed in 4 patients (25%). Five patients were evaluanle for the development of chronic GVHD. 2 patients(40%) developed limited chronic GVHD. Respiratory complications including pulmonary infection developed in 10 patients(50%) and these complications were the most common primary cause of death. Of these 10patients, 6 had pneumonia due to fungus(4 patients), pacterial (1 patient), and CMV infection (1 patient) and 4(20%) had idiopathic interstitial pneumonitis and/or adult respiratory distress syndrome. The duration of median follow- up was 8.5 months and 7 of 20 patients(35%) are alive at the time of this analysis with survival duration of 0.5 to 15 months(median survival duration: 4 months). The overall survival was 25% (3/12 patients) in high risk group and 50%(4/8 patients) in standard group. From these results, we can predict that the incidence and severity of GVHD in Korea are lesser than multiracial countries and the long-term survival of patients with standard risk disease can approach that of HLA matched sibling transplants. For the past two years, the performance of UBMT has been rapidly increasing and it will be possible to analyze much larger number of patients soon in Korea. In the future the problems of graft failure, GVHD, and infection due to long lasting immunocompromised status will need to be overcome by continued medical research. In addition, the volunteer donor pool will have to be expanded by the promotion of the national awareness of its need.

Recently, Polymer Dispersed Liquid Crystal(PDLC) films have been invastigated as an infomation display and a switchable window. In this work, PDLC films were prepared by solvent-induced phase separation method using PS, PMMA, and PS/PMMA copolymer as polymer substrate with 5CB(4'-Pentyl-4-biphenylcarbonitrile) as low molecular weight liquid crystal. Optical microscopy was used to determine degree of dispersion, the size and shape of LC droplet. The beheavior of phase transition of PDLC film as a function of temperature was investigated by using optical microscope with heating stage. In addition electro-optic properties were measured by using He-Ne laser with photodiode during applying 60Hz AC to the PDLC film. LC phase was unifomly embedded in polymer substrate and the sizes of LC droplet were decreased in the order of PMMA/LC > copolymer/LC > PS/LC. Light transmittance of PDLC film was increased with applied voltage and temperature increasing, Critical applied voltages were deacreased as PMMA/LC > copolymer/LC > PS/LC, while light contrast ratios were charged with reverse order.

The present study was conducted to elucidate some characteristics of soy protein hydrolysates. The soy protein was obtained from defatted soy power by the treatment of n-hexan. The hydrolysates of soy protein were prepared from hydrolysis by bromelian and pepsin with the two kinds of samples of precooking for 30 min in steam oven and noncooking, and fractionated through Bio-gel P-4 column chromatography. Fractions of hydrolysates separated on the Bio-gel column chromatography were carried out to SDS-PAG electrophoresis, resulting to show some different bends from 66kD to 14.2kD of molecular weight. In addition, the fractions showed different activities of superoxide dismutase. From these results, it was found that the hydrolysates could be available to use in a lot of food industrial fields as new functional food materials because the hydrolysates had different characteristics in electrophoresis and could increase the activity of superoxide dismutase.

Selective posterior rhizotomy(SPR) has been known to reduce the spasticity as well as to improve the quality of life in patients with intractable spasticity. Twenty patients underwent SPR under intraoperative electrophysiological monitoring(IOM). Fifty-two percent of sacrolumbar rootlet were cut after electrical stimulation. Eighteen patients(90%) with spastic type of cerebral palsy showed marked reduction of spasticity and functional improvement without any complication. The patients who did not respond to SRP had mixed types of spasticity. IOM facilitate the selection of pathological rootlets regardless of anaesthetic level. intensity of electrical stimulation, and individual variability of responses. It is concluded that careful selection of surgical candidates and of pathological rootlets under IOM are important to reduce the spasticity. thereby to obtain a better outcome.
