The objective of this study was to investigate clinical manifestations of lower extremity edema (LEE) in endometrial cancer Medical records for LEE and/or responses to the Gynecologic Cancer Lymphedema Questionnaire (GCLQ) were evaluated in 177 patients with endometrial cancer Patients had a median age of 53 years. Sixty-seven patients (37.9%) had past (9 patients, 13.4%) and/or current patient-reported LEE (58 patients, 86.6%). Symptoms reported on the GCLQ in over 20% of respondents were swelling, numbness, aching , and heaviness. GCLQ total symptoms score was significantly higher in patients with current LEE. Most of the LEE (43/67, 64.2%) developed within 12 months after surgery and LEE lasted more than 6 months in most patients (56/59, 94.9%) Prospective clinical trials are needed to know the clinical significance, impact on quality of life, and preventive strategy of LEE in patients with endometrial cancer

이재원,이석영,이형래,이상철,김용태,김원재 충북대학교 의학연구소 2002 忠北醫大學術誌 Vol.12 No.2

연구목적: 전립선비대증은 노화현상에 의해 발생하는 질환으로서 임상적으로 주로 50세 이상에서 증상이 나타난다. 산소 라디칼은 DNA의 염기에 다양한 손상을 미칠 수 있다. 산소 라디칼에 의한 DNA의 변화에는 여러 가지 형태가 있으며 이러한 변화들 가운데서 guanine이 8-oxoguanine (8-hydroxyguanine, oh8Gua)으로의 수산화(hydroxylation) 반응은 가장 흔히 관찰되는 형태로서 노화 및 만성 퇴행성 질환, 기타 여러 질환의 중요한 병인으로 인식되고 있다. 세포에 유해한 영향을 주는 oh8Gua의 생성으로부터 유전자를 보호하는 수복효소 중 8-oxoguanine-DNA glycosylase (OGG1)가 주된 역할을 하는 것으로 알려져 있는데 이 효소를 생산하는 유전자인 hOGG1은 사람마다 유전자형이 다르다. 따라서 본 연구에서는 전립선비대증이 노화와 관련된 hOGG1 유전자형에 따라서 발생에 차이가 있는지를 조사하였다. 대상 및 방법: 충북대학교 병원에서 전립선비대증으로 진단 받고 입원하여 경요도전립선절제술을 받은 환자로 병리 조직학적으로 전립선비대증이 확인된 81명을 환자군으로 하였으며, 충청북도내 10개 군에서 50세 이상의 건강한 성인 남자 764명을 대상으로 실시한 전립선 무료검진에서 경직장 초음파 검사상 전립선 크기 20 gm 이하, 국제 전립선 증상 점수(IPSS) 7점 이하, 요속 10 ㎖/s 이상, 전립선 특이 항원(PSA) 4.0 ng/㎖ 이하인 81명을 대조군으로 설정하였다. 이들에서 채취한 혈액에서 genomic DNA를 얻은 후 PCR-SSCP (polymerase chain reaction-single stranded conformation polymorphism), 직접 염기서열분석(direct DNA sequencing) 및 RFLP (restriction fragment length polymorphism)를 통해서 두 군 사이의 hOGG1 유전자의 다형성을 분석하였다. 결과: 대조군에서 codon 326형은 Ser326Ser형이 12례(14.8%), Ser326Cys형이 51례(63.0%), Cys326Cys형이 18례(22.2%)였으며 전립선비대증 환자군에서는 Ser326Ser형이 15례(18.5%), Ser326Cys형이 34례(42.0%), Cys326Cys형이 32례(39.5%)로 두 군 사이에 통계적인 유의성이 관찰되었다(p=0.022). 또한 Cys326Cys형과 나머지(Ser326Ser, Ser326Cys)형으로 나누어 시행한 통계 분석에서도 대조군에서는 각각 18례(22.2%), 63례(77.8%)였으며 전립선비대증 환자군에서는 32례(39.5%), 49례(60.5%)로 통계적인 유의성이 관찰되었다(p=0.017, OR=2.286, 95% CI=1.149-4.546). 결론: hOGG1 유전자의 형태와 전립선비대증의 발생과는 밀접한 관련이 있었다. 즉 hOGG1 Cys326Cys형을 가진 사람에서 전립선비대증이 발생한 가능성이 높을 것으로 사료된다. Purpose: 8-oxoguanine DNA glycosylase (OSS1) rapairs DNA by removing 8-oxoguanine (oh8Gua), a highly mutagenic oxidative DNA adduct. Recently, the human gene for OGG1 (hOGG1) was cloned and several genotypes have been reported. However, the implications of such genotypes in benign prostatic lyperplasia have not been demonstrated. To assess the involvement of hOGG1 associated with the aging process on the developing of BPH, we analyzed the genetic polymorphisms of hOGG1. Materials and Methods: We studied the hOGG1 gene polymorphisms in 81 cases of BPH and 81 cases of normal controls. We performed the SSCP, PCR-based restriction fragment length polymorphism (RFLP) and direct sequencing to characterize the genetic polymorphisms of hOGG1 in both BPH patients and controls. Results: We found two polymorphic sites. A serine326/cysteine polymorphism at codon 326 (1a type) in exon 7 was associated with an exchange of amino acid. Another polymorphic site at codon 324 (1b type) in exon 6 was silent. We found that the distribution of hOGG1 genotypes in BPH patients (Ser326Ser type 18.5%, Ser326Cys type 42.0% and Cys326Cys type 39.5%) was significantly different from that in controls (14.8%, 63.0% and 22.2%, respectively) (p=0.022). Homozygosity for the Cys326Cys genotype significantly increased the risk of developing BPH, with the odds ratio (OR) being 2.286 (95% confidence interval [CI]=1.149-4.546) Conclusion: Our results suggest that the hOGG1 Cys326Cys genotype might play a important role in the development of BPH.

목적 : 2002년 말 중국에서 SARS가 발생한 이후 국내에서도 2003년 10월까지 총 3명의 추정환자, 17명의 의심환자가 보고되었다. 향후 추가적인 SARS의 유행이 우려되는 상황에서, 그간의 SARS 환자 진료에 있어서의 실질적인 준비사항, 진료 현황 등에 대한 조사를 통해 문제점을 파악하여, 향후 더 나은 대비가 될 수 있도록 개선점을 제시하고자 하였다. 재료 및 방법 : SARS로 의심되는 환자를 진료 경험이 있는 병원의료진을 대상으로 2003년 10월에 설문조사를 실시하였다. 설문에는 SARS 환자 진료 시의 실질적인 조치, 진료 현황, 병실, 응급실 및 외래에서의 격리 시설과 준비사항, 보건당국의 관리와 지원에 관한 사항을 포함하였다. 결과 : 대상이 되는 22개 병원 중 17개(17/22, 77.2%) 병원이 설문에 응하였다. SARS 환자를 위한 격리실은 응급실, 외래, 일반병실 및 중환자실에서 각각 9개(9/17, 52.9%), 5개(5/17, 29.4%), 15개(15/16, 93.7%), 4개(4/16, 25%) 병원에서 음압처리가 되어있지 않은 일인실 혹은 다인실이 사용되었고, 1개(1/16, 6.3%) 병원에서만 일반병실에서 음압격리실이 운영되었다. 입원환자의 진찰 시 개인보호구의 착용은 거의 모든 의료기관에서 이루어졌다. 보건당국에서 SARS지정병원의 시설 등을 사전에 확인한 곳은 1곳(1/12, 8.3%)이였고, 14개 병원(14/15, 93.3%)에서는 보건당국에 의뢰한 검사결과를 통하 받지 못하였다. 결론 : 의료기관에서 SARS 환자용 격리실뿐만 아니라 기존의 격리실 설비 등이 미흡하였으며, 특히 중환자실 및 외래의 준비가 더욱 부족하였다. 보건당국의 의료기관에 대한 종합적인 지원이 부족하였고, 병원과의 원활한 연계가 잘 이루어지지 않았다. SARS 만이 아닌 격리를 필요로 하는 질환의 적절한 진료를 위해 향후 병원 시설의 정비와 정부차원에서의 보다 구체적이고 실질적인 대책마련이 필요하다. Background : There was an worldwide outbreak of the Severe Acute Respiratory Syndrome (SARS) originated from China in late 2002. During that period three cases of suspected SARS and 17 cases of probable SARS were reported in Korea. With the concerns about the reemergence of SARS-coV transmission, it is important to be prepared for any possibility. So, this study is aimed to analysis the past measures in managing SARS and propose the amendatory plans to improve the preparedness. Materials & Methods : Questionnaires were collected among clinicians with any experience in managing the probable or suspected SARS cases in Oct. 2003. 17 out of 22 hospitals responded to the questionnaire. The contents in the questionnaire were practical activities, personal equipments, response plans, isolation facilities in emergency centers, outpatient clinics, general wards and intensive care units, and relationship with the public health department. Results : The dedicated isolation rooms in emergency centers, outpatient clinics, general wards, and intensive care units were prepared in 9 (9/17, 52.9%), 5 (5/17, 29.4%), 15 (15/16, 93.7%), and 4 (4/16, 25.0%) hospitals, respectively. Except for one hospital that newly made negative pressure room for SARS, single or multi-bed rooms without airborne infection control were used in all the other hospitals. The personal precaution principles were kept quite well in general wards. Before the designation of SARS hospital by the public health department prior evalution to see if the hospital was suitable for managing SARS was conducted in only 1 (1/12, 8.3%) hospital. The results of laboratory diagnosis were reported back in 1 (1/15, 6.6%) hospital. Conclusions : The isolation facilities which can control airborne infection were almost deficient not only for SARS but also for other respiratory transmissible diseases. For the infection control of transmissible diseases including SARS, more investment is needed on medical facilities and comprehensive support from the public health department required.

연구목적 : 본 시험의 목적은 임상시험 시작전에 연구자들을 대상으로 PANSS Workshop을 통하여 PANSS, ESRS에 대한 국내에서의 표준화 작업을 구축하고 새로운 정신병 치료제인 리스페리돈의 효과와 안정성을 재확인하여 리스페리돈 사용에 대한 적정화를 이루는데 있다. 연구방법 : 1996년 4월부터 1996년 9월까지 국내 39개 대학병원 정신과에 입원중인 혹은 증상이 악화되어 입원하는 정신분열병 환자 377명을 대상으로 다시설 개방 연구를 시행하였다. 1주일간의 약물 배설기간을 가진후, 리스페리돈을 8주간 투여하였고, 기준점, 1주, 2주, 4주, 그리고 8주후에 평가되었다. 용량은 제1일에는 리스페리돈 1mg씩 1일 2회, 제2일에는 2mg씩 1일 2회, 제3∼7일에는 3mg씩 1일 2회 투여하였다. 이후 환자의 임상상태에 따라 임의로 증량할 수 있으며, 최대 일일 16mg을 초과하지 않도록 하였다. 추체외로 증상을 조절하기 위한 투약을 허용하였다. 임상증상 및 부작용의 평가는 PANSS(Positive and Negative Syndrome Scale), CGI(Clinical Global Impression) 그리고 ESRS(Extrapyramidal Symptom Rating Scale)을 사용하였다. 연구결과 : 377명중 343명(91%)이 8주간의 연구를 완결하였다. 치료 종결시점인 8주후 PANSS 총점수가 20% 이상 호전된 경우를 약물 반응군으로 정의할때, 약물반응군은 81.3%였다. 리스페리돈에 반응하는 예측인자로는 발병연령, 이전의 입원 횟수, 유병기간이 관련 있었다. 리스페리돈은 1주후부터 PANSS양성, 음성, 및 일반정신병리 점수상에 유의한 호전을 보여 효과가 빨랐다. CGI의 경우도 기준점에 비해 1주후부터 유의한 감소를 나타내었다. ESRS의 경우, 파킨슨 평가점수는 기준점과 비교해 투여 1주, 2주, 4주후 유의하게 증가되었다가 8주후 기준점과 차이가 없었다. Dystonia 평가점수는 1주후만 유의한 증가를 보였으며, dyskinesia 평가점수는 유의한 차이가 없었다. 혈압, 맥박수의 생명징후 및 일반 혈액학 검사, 생화학적 검사, 심전도 검사에서 유의한 변화는 없었다. 결 론 : 이상의 다시설 개방 임상 연구를 통해 리스페리돈은 정신분열병 환자에서 양성증상뿐만 아니라 음성증상 및 전반적인 증상에도 효과적인 것으로 사료된다. 보다 명확한 평가를 위해서는 다른 항정신병약물과의 이중맹검 연구가 필요할 것으로 생각되며, 또한 장기적 치료에 대한 평가도 함께 이루어져야 하겠다. Objective : The purpose of this study was to investigate the efficacy and safety of risperidone in the treatment of Korean schizophrenic patients. Method : This multicenter open study included 377 schizophrenic patients drawn from 39 university hospitals. After a wash-out period of 1 week, the schizophrenic patients were treated with risperidone for 8 weeks and evaluated at 5 points ; at baseline, and 1, 2, 4 and 8 weeks of treatment. The dose was increased from 2mg/day(1mg twice daily) to 6mg/day(3mg twice daily) during the first week and adjusted to a maximum of 16mg/day over the next 7 weeks according to the patient's clinical response. Medication to control extrapyramidal symptoms was permitted. The psychiatric and neurological status of the patients was assessed by PANSS, CGI, and ESRS scales. Results : 343(91%) of 377 patients completed the 8-week trial period. Clinical improvement, as defined by a 20% or more reduction in total PANSS score at end point, was shown by 81.3% of patients. The predictors of response to risperidone were associated older age, shorter duration of illness, fewer previous hospitalization. Risperidone had rapid onset of action ; a significant decrease of the total PANSS and three PANSS factor(positive, negative, general), and CGI was already noticed at the end of first week. For the ESRS, parkinsonism rating scores were significantly increased until week 4 comparing with baseline. Dystonia rating scores were significantly increased until week 1, and dyskinesia rating scores were not significantly changed during the study. Laboratory parameters including vital sign, EKG, hematological, and biochemical values showed no significant changes during the trial. Conclusions : This study suggests that risperidone is generally safe and effective against both the positive and negative symptoms in our group of patients.

In order to obtain an useful information for health management and biological monitoring of lead exposed workers, Authors tried to investigate air lead level and the lead exposed level of workers in lead industry according to occupational category. The subjects in our study were 2074 workers in 7 lead-using industries, and study subjects were divided into 4 occupational categories such as storage battery industry (type 1), primary smelting industry (type 2), secondary smelting industry (type 3) and litharge making industry (type 4). Blood zincprotoporphyrin concentration (ZPP), blood lead concentration (PbB) and urinary δ -aminolevulinic acid (ALAU), hemoglobin (Hb), hematocrit (Hct) were selected as the indices of lead exposure. Personal variables such as age, work duration were also collected. The results were as follows. 1. The geometric mean air lead in 9 lead-using industry was 0.1133±4.3120 ㎎/㎥, and that in type 1, 2, 3 and 4 was 0.1038±3.4952 ㎎/㎥, 0.0429±3.4329 ㎎/㎥, 0.1877±2.5123 ㎎/㎥ and 0.9961±5.2910 ㎎/㎥, respectively. 2. The mean ZPP in 9 lead-using industry was 53.1±28.0 ㎍/㎗, and that in type 1, 2, 3 and 4 was 52.0±24.8 ㎍/㎗, 48.0±16.4 ㎍/㎗, 109.8±85.6 ㎍/㎗ and 74.3±37.8 ㎍/㎗, respectively. There was significant difference in ZPP according to occupational category (P<0.01). The percents of lead workers whose ZPP were above 100 ㎍/㎗ in type 1, 2, 3 and 4 were 4.0%, 1.7%, 34.3% and 21.6%, respectively. 3. The mean PbB in lead-using industry was 26.0±11.2 ㎍/㎗, and that in type 1, 2, 3 and 4 was 25.3±11.1 ㎍/㎗, 26.7±8.8 ㎍/㎗, 50.3±15.2 ㎍/㎗ and 36.4±11.0 ㎍/㎗, respectively. There was significant difference in PbB according to occupational category (P<0.01). The percents of lead workers whose PbB were above 40 ㎍/㎗ in type 1, 2, 3 and 4 were 10.4%, 7.7% 71.9% and 43.2%, respectively. 4. While the correlation of Hb corrected PbB with ZPP was higher than non corrected PbB, the correlation of log-transformed ZPP with PbB was higher than non corrected ZPP. 5. Simple linear regressions of PbB and corrected PbB as independent variable with ZPP, log-transformed ZPP and ALAU as dependent variable were statistically significant (P0.01). Coefficient of determination of corrected PbB with other variables was higher than non corrected PbB. As the result of this study, it was suggested that reconsideration of environmental and biological monitoring program was highly recommended for secondary smelting and litharge making industry.

Three different treatments for induction of estrus in Korean native black goats were compared: follicle stimulating hormone(FSH, FSH-p^TM), FSH combined with MAP(intravaginal impregnated sponges, Veramix^ⓡ, containing 60 ㎎ medroxy progesterone acetate for 14 days), and FSH combined with progesterone(Ovaron^ⓡ, 10 ㎎ IM for 10 days) and PGF_2α(Lutalyse^ⓡ, 3 ㎎ IM at first FSH injection). FSH for inducing estrus and superovulation was given a total 20 ㎎ intramuscularilly in decreasing dosage injections twice daily over 4 days. The MAPs were withdrawn at the 3rd day of FSH injection. Estrus observations were conducted every 6 hours from last FSH injection for 24 hours by placing the does with fertile male goats. Estrus and superovulation were more successfully induced with treatment of MAP + FSH than other treatments(FSH only, or progesterone + PGF_2α + FSH) (estrus induction; 100 vs 42.8 and 71.4%, ovulation points; 11.4 vs 5.4 and 4.4, respectively). The effect of gonadotropin releasing hormone(GnRH) on the ovulation rate was also examined. However, no difference was observed for inducing ovulation with treatment or dosage(100 ㎍ 200 ㎍) of GnRH. Low midline laparotomies were performed, and then ovarian responses (ovulations and follicular development) were examined by exteriorization of the reproductive tracts. Ova were recovered from oviducts by retrograde flushing 60-146 hours after MAP removal, and were classified the developmental stages. Overall 66.1% (236/357) of recovery rate was obtained from 30 superovulated does. The optimal recovery time of microinjectable 1-cell zygotes was approximately 72-76 hours after MAP removal.

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.
