Bioequivalence of two cilostazol tablets, the Pletaal^(R)(Korea Otsuka Pharmaceutical Co., Ltd.) and the Cilozol^(R)(Hanmi Pharmaceutical Co., Ltd.), was evaluated according to the guideline of KFDA, Sixteen normal male volunteers(age 20~29 years old) were divided into two groups and a randomized 22 cross-over study was employed. After two tablets containing 50㎎ of cilostazol were orally administered. blood was taken at predetermined time intervals and the concentration of cilostazol in plasma was determined with an HPLC method using UV detector. The pharmacokinetic parameters(C_(max), T_(max) and AUC_(t)) were calculated and ANOVA was utilized for the statistical analysis of parameters. The results showed that the differences in C_(max), T_(max) and AUC_(t) between two tablets were 4.99%, 1.74% and 7.68%, respectively. The powers(1-β) for C_(max), T_(max) and AUC_(t) were83.92%, 80.12% and 85.03%, respectively. Detectable differences(Δ) and confidence intervals were all less than 20%, and confidence interval of all the parameters were also less than 20% at the significance level(α) of 0.05. All of these parameters met the criteria of KFDA for bioequivalence, indicating that Cilozol^(R) tablet is bioequivalent to Pletaal^(R) tablet.

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.

최정순,이희종,공수강,리투,류용구,김효준 한양대학교 이학기술연구소 2005 이학기술연구지 Vol.8 No.-

Apo B-100 is a constitutive component of low density lipoprotein (LDL) of which functions in packaging, transport and absorption of lipids Extortive binding of anti B_(4)-antibody onto the Apo B-100 should inhibited the functions of Apo B-100 Previously we had showed that the peptide B_(4) induced antibodies recognized Apo B-100 and thus elicited anti-obesity effect In this study we compared the efficacy of antibody inducing immune responses by introducing additional peptides fused to the C-termninal of B_(4) peptide We constructed TB_(4) hybride peptide of B_(4) with preS2 of HBV and B_(4)N another epitope orientation of chimeric TB_(4) Among these three artificial peptides B_(4)N was the most efficient inducer of the antibody against B_(4) These result explains that the B cell epitope and T-helper cell epitope orientation is very important factor to determine the antigenicity to humoral immunity. Apo B-100은 LDL에서 지방을 포장, 흡수, 운반하는 기능을 수행하는 단백질이다. Apolipoprotein B-100(Apo B-100)에 대한 특이 항체의 결합은 LDL의 정상 기능을 방해한다. 선행 실험에서 Apo B-100의 모조 펩타이드인 B_(4)가 Apo-B-100을 교차 인식하는 항체를 유도하고, 비만 억제 효과를 나타내는 것으로 밝혀졌다. 본 연구에서 B_(4)펩타이드의 C-terminal부분에 펩타이드를 융합, 첨가하므로 면역반응에서 항체유도의 면역응답반응에 어떠한 효과를 나타내는지 비교해 보고자 하였다. B_(4)펩타이드의 N-말단에 HBV의preS2 펩티드를 융합시킨 B_(4)T의 N-말단데 또다른 B세포 에피도프 펩티드를 융합시킨 B_(4)N을 작성하였다, 세종류의 하이브리드 펩타이드 중에서 B_(4)N이 B_(4)에 대한 항체유도능이 가장 효율적이다,. 이상의 결과로 B cell epitope과 T-helper cell epitope의 방향성이 체액성 면역 반응에서 항원유도능을 결정하는 중요한 요소임을 확인하였다.

조혈모세포이식 환자에서 침습성 진균 감염에 대한 이트라코나졸 액과 플루코나졸 시럽의 예방 효과 : 전향적, 무작위, 비교 임상시험

최수미,이동건,최정현,박선희,엄기성,김유진,김희제,민창기,유진홍,김동욱,이종욱,민우성,신완식,김춘추 대한감염학회 2005 감염과 화학요법 Vol.37 No.2

목적 : 조혈모세포이식 환자에서 호중구 감소 기간 동안 이트라코나졸 액(ITZS)과 플루코나졸 시럽(FCZS)의 진균 감염에 대한 예방 효과를 전향적으로 비교해 보고자 하였다. 재료 및 방법 : 2001년 8월부터 2002년 6월까지 가톨릭 조혈모세포이식센터에 입원하여 동종 조혈모세포이식을 받은 만 18세 이상의 환자들을 각각 ITZS와 FCZS군으로 무작위 배정하여 침습성 진균 감염 발생과 약제 관련 부작용을 전향적으로 조사하였다. 결과 : ITZS군에 40명, FCZS군에 38명이 배정되었고, FCZS군 환자의 평균 나이가 더 많았다. 시험 약제 평균투여기간은 ITZS군 16.4일, FCZS군 21.9일로 ITZS군이 더 짧았다. 이는 ITZS군에서 소화기 부작용으로 인한 약제 중단이 더 많았기 때문으로 보인다. 시험 약제 투여 후 총 빌리루빈 수치의 유의한 증가가 관찰되었으나, 약제 관련 부작용은 모든 환자에서 가역적이었다. 호중구감소 기간동안 표재성 진균 감염은 두 군에서 모두 발생하지 않았고, 침습성 진균 감염은 ITZS군 5명(12.5%), FCZS군 8명(21.1%)으로 FCZS군에서 많았으나, 통계학적으로 유의하지 않았고, 사망률에도 유의한 차이는 없었다. 결론 : 침습성 진균 감염에 대한 이트라코나졸 액과플루코라졸 시럽의 예방 효과에 유의한 차이는 없었으나, 앞으로 더 많은 환자를 대상으로 잘 짝지어진 대조군 연구가 필요할 것으로 보인다. 부작용 중 간독성과 관련하여 이식시 투여되는 여러 약제들과의 상호작용에 대한 연구도 필요할 것이다. Background : Though fluconazole is widely used for antifungal prophylaxis, it is ineffective against mould infections including Aspergillus species. Itraconazole has a broader spectrum than fluconazole but the capsule form shows erratic bioavailability in neutropenic patients. In this study, we compared itraconazole oral solution (ITZS) with fluconazole syrup (FCZS) for the prevention of invasive fungal infection (IFI) in allogeneic hematopoietic stem cell transplant recipients. Materials and Methods : Adults receiving allogeneic hematopoietic stem cell transplantation (HSCT) from september 2001 to June 2002, were randomly allocated to either the ITZS group or the FCZS group. We prospectively evaluated the safety and efficacy of each drug. Results : Out of 78 patients (40 patients in the ITZS group and 38 patients in the FCZS group) who were eligible for this study, 37 patients completed the course of prophylaxis without any evidence of IFI. The mean duration of prophylaxis was 16.4 days for the ITZS group and 21.9 days for the FCZS group (P<0.006). Drug-related adverse events occurred in 28 patients (70.0%) and 19 patients (50.0%) in the ITZS group and the FCZS group, respectively. Common adverse events of ITZS were nausea, vomiting, and diarrhea. Drug-related reversible hepatotoxicity occurred in 4 patients in the ITZS group. There was a significant elevation of total bilirubin level in the ITZS group. The incidence of suspected IFI occurred in 5 patients (12.5%) who received ITZS, compared with 8 (21.1%) who received FCZS (P=0.372). There were no proven IFIs or superficial (oral/vaginal) fungal infections in both groups. Overall mortality was not different between the two groups (2.5% in the ITZS group versus 5.3% in the FCZS group, P=0.610). Conclusion : ITZS and FCZS showed similar protection against IFI during pre-engraftment period. Poor tolerability due to gastrointestinal troubles of ITZS might limit its success as prophylactic therapy. Well matched controlled study with large number of patients will be required in the future.

조혈모세포이식 환자에서 발생한 Cytomegalovirus 질환의 특징 : 일개 대학변원에서 최근 10년간의 경험

Background : Studies on cytomegalovirus (CMV) diseases in Korean hematopoietic stem cell transplant (HSCT) recipients are lacking and do not reflect the recent trends of advances and changes. Therefore, we tried to analyze the clinical features of CMV diseases in HSCT recipients over the past 10 years at a tertiary university hospital in Korea. Methods : Retrospective review of medical records was done for all adult HSCT patients who received transplant at the Catholic HSCT Center from January 1998 to January 2008. Results : Forty-four cases (2.2%) of CMV diseases were identified. CMV pneumonia was diagnosed in 17 patients, retinitis in 16 patients, enterocolitis in 7 patients, esophagitis 1 patient, gastritis in 1 patient, duodenitis in 1 patient, and hepatitis in 1 patient. The median onset of symptom was 90 days after transplantation. Late CMV diseases accounted for 47.7%. CMV related death varied from 0 to 58.8% according to the involved organ. CMV retinitis was diagnosed relatively later in the course of transplantation mostly in patients who had chronic graft versus host disease (GVHD). On the contrary, CMV enterocolitis mainly occurred in patients who suffered from acute GVHD. The overall concurrent CMV reactivation was documented to be 63.6%: the concurrent CMV reactivation was observed only in 37.5% of patients with retinitis. Conclusions : We observed some differences in the pattern of CMV disease manifestation according to the involved organ and reconfirmed the fact that CMV pneumonia is the most common and fatal disease in HSCT recipients. Additionally, CMV retinitis was not uncommon in HSCT recipients. Since specific marker does not exist in predicting retinitis, regular ocular examination should be done thoroughly, especially in patients with chronic GVHD.

인공효소 8-azaflavin이 기질과의 반응성

최종정,이용희,이동환 한국공업화학회 2004 응용화학 Vol.8 No.2

8-azaflavin was synthesized by condensation of 4-amino-3-N-methylamino pyridune and N-methylalloxane. An oxidation-active flavin mimic contributed substantially to flavin chemistry in model systems. One of the ways of exploting oxidation-active flavin mimics could be by introducing electron-withdrawing groups into the isoalloxazine ring thus providing an electron dificient flavin. We report that 8-azaflavin show remarkably high oxidizing activities for the oxidations of N-benzyl-1,4-dihydronicotinamide(BNAH) and nitroalkanes in aqueous solution.

달성 도동서원의 경관보존관리방안

최종희, 김규연 배재대학교 자연과학연구소 2014 自然科學論文集 Vol.25 No.1

본 연구는 달성 도동서원의 보호구역 설정 및 이에 따른 경관보존관리방안 마련을 위한 연구로서 집약된 결론은 다음과 같다. 첫째, 보존권역 설정의 경우, 주산인 대니산과 안산인 제석산, 명당수인 낙동강을 기점으로 성리학적 자연관에 입각한 서원의 입지, 김굉필 묘소 등 배향인물과 관련된 문화적 요소, 수월루를 경관조망점으로 하는 경관가시권역, 토지용도, 지적사항 등을 고려한 체계적인 보호권역 설정의 타당성을 제시하였다. 둘째, 조망경관확보의 경우 초근경과 근경의 경우 서원 전면의 주차장과 도로가 조망경관 저해 요소로 작용하여 향후 원형경관을 회복하기 위해서는 수월루의 전면에 위치한 안산과 명당수로의 조망이 확보되어야 함을 파악할 수 있었다. 셋째, 식생경관 회복의 경우, 현재 경내를 중심으로 공간성격에 부합하지 않는 수종이 식재되어 있는 바, 식재수종과 위치 및 재식방법에 대해 문헌적 고증을 통한 복원 및 정비가 이루어져야함을 파악할 수 있었다. 넷째, 시설물의 경우 재료와 형태의 혼재 및 동선체계와 연계 없이 설치되어 있고, 안전시설의 경우 노후화되고 파손된 시설이 그대로 외부로 노출되어 적절한 정비가 요구 되는 바, 향후 서원의 경내 및 외부공간의 공공시설물의 디자인 지침 마련의 필요성을 파악할 수 있었다.
