In recent years, gonorrhea has been pandemic and remains one of the most common STDs in the world, especially in developing countries. For the detection of a more effective therapeutic regimen and assessing the prevalence of Penicillinase Producing Neisseria gonorrhoeae(PPNG), we have been trying to study the patients who have visited the Venereal Disease Clinic of Choong-Ku Public Health Center in Seoul since 1980 by menas of the chromogenic cephalosporin method. In 1998, 93 strians of N. genorrhoeae were isolated, among which 60(64.5%) were PPNG. The prevalence of PPNG in Seoul, which had been decreased to 39% in 1996 after a peak of 74.3% in 1993, is increased to 64.5% in 1998.

표준균주를 포함한 230여개의 김치유래 젖산균에 대한 균체지방산(FAMEs)을 분석하였다. FAMEs profiles는 Euclidian Distance 17.5에 의해 7개의 Major Cluster와 1개의 Single Cluster로 나뉘어졌다. 이중 A, B, C 및 Cluster는 Leuconostoc속으로 분석되어졌고, F는 Lactobacillus속으로 분석되어졌다. 그리고 E와 G cluster는 두개의 Genus가 혼재되어 나타났으며 보충적인 연구가 필요하다. 앞으로 김치유래 젖산균의 균체지방산 분석결과를 기반으로 한 데이타베이스에 95가지 탄소원을 이용하는 수치분류학적 접근방법 및 Pyrolysis Mass Spectrometry 등의 화학적 분석 방법과 분자친화적 연구를 통한 종합적 분류정보 체계가 갖추어지면 젖산균의 신속, 정확한 동정 및 연구에 활발히 이용되어질 것이다. Two hundreds and thirty lactic acid bacteria, mostly isolated from Kimchi, including type strains were sued for analysis of cellular fatty acids. The 230 test strains were recoverd in 7 major and 1 single clusters defined a Euclidian distance of 17.5. These aggregate taxa were equivalent to the genus Leuconostoc (aggregate group A, B, C and D), and the genera Leuconostoc and Lactobacillus (aggregate group G). It is concluded as evident that FAMEs (Fatty Acid Methyl Esters) profile of cell can be used as a criterion in classification of lactic acid bacterial from kimchi. Additional comparative taxonomic studies need to be carried out on well chosen representative strains to determine the most appropriate methods of value.

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.

황기桃紅湯이 Endotoxin으로 유발된 白鼠의 血栓症에 미치는 영향

田炳薰,李鎭弘,鄭鉉雨,禹元洪,鄭遇悅 대한동의병리학회 1993 동의생리병리학회지 Vol.8 No.-

연구배경 : 최근의 死亡率중에 腦血管系疾患이 차지하고 있는 比率이 대단히 높기 때문에 氣와 血의 이론적 관계인 "氣爲血之帥, 氣行則血行." 의 관점하에서 腦血管系疾患중의 하나인 血栓病을 동의학적 병리론에 의거하여 "瘀血"의 범주에 속할 것으로 사료되기 때문에 補氣之劑인 황기를 君藥으로하고 活血祛瘀之劑인 桃仁과 紅花를 加하여 실시하기로 하였다. 그리하여 본 연구가 임상에서 血栓症治療에 應用할 수 있는지를 考察하고, 작게는 東醫學 發展의 이론적 뒷받침이 되었으면 하는 바램에서 시행하였다. 방법 : 황기도홍탕이 1첩분량(318.75g)을 100ml로 減壓濃縮하여 0.2mg/kg의 endotoxin을 試料投與 1시간 후에 白鼠의 尾靜脈에 注入하고 4시간이 경과되면 urethane 痲醉下에서 心臟採血 하였다. 결과 : 血小板數와 FDP는 對照群에 비하여 增加 또는 減少되었지만 有意性은 나타내지 않았다. 그러나 prothrombin time과 fibrinogen량은 對照群에 비하여 有意性있게 短縮 또는 增加하였다. 결론 : 황기도홍탕이 endotoxin으로 誘發된 白鼠의 血栓症에 미치는 影響은 有意한 것으로 나타났다. 그렇기 때문에 黃?桃紅湯이 腦血管疾患 뿐만 아니라 瘀血性疾患에 임상적으로 응용하면 보다 높은 치료효과를 거두리라 思料된다 This study was performed to investigate the effect of Whangkidohongtang(황기도홍탕) on the intravascular coagulation induced by endotoxin in rats. The intravascular coagulation was induced by injecting endotoxin in the caudal vein of rats. And these rats were treated with extract of Whangkidohongtang(황기도홍탕)1.0ml/200g (GroupⅠ) and Whangkidohongtang(황기도홍탕) 2.0ml/200g (groupⅡ), which were administered orally. Then, the number of blood cells, platelets, concentration of prothrombin time, fibrinogen and FDP(fibrin-fibrinogen degradation products) were measured. The following results were obtained : 1. The number of platelets increased in the GroupⅡcompared with the control group, but it is not significant. 2. The prothrombin time was shortened significantly in the GroupⅡcompared with the control group. 3. The concentration of fibrinogen increased significantly in the trial group compared with the control group. 4. The degree of concentration of FDP decreased significantly in the trial group compared with the control group, but it is not significantly. According to the above results, it is considered that Whangkidohongtang(황기도홍탕) has the significant effects on thrombosis. Therefore, Whangkidohongtang(황기도홍탕) seems to be applicable to the diseases related to thrombosis.

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.

Aims: We aimed to evaluate the efficacy and safety of Daclatasvir (DAV) and Asunaprevir (ASV) in patients with chronic hepatitis C virus (HCV) and chronic renal failure (CRF). Methods: 22 chronic hemodialysis patients with HCV infection at 12 medical centers have prospectively enrolled from Feb, 2016 to Feb, 2017 (NCT02580474). Of those, 9 patients who were followed 12 weeks after treatment ended were included. We evaluated the virological responses at each week 4, 12, 24 and the 12-week sustained virologic response (SVR12). The tolerability and safety of patients were also evaluated. Results: Of these 20 patients, there had no resistance-associated variant of NS5A (NS5A RAVs) and 2 patients showed indeterminate NS5A RAVs. 12 patients (54.5%) completed the 24 weeks treatment of DAV and ASV. 6 patients (27.2%) have continued, but 4 patients discontinued study prior to 12 weeks. Overall, all patients (n=9) achieved SVR12. Virologic response at week 4, 12 and 24 showed 94.4% (17/18), 93.3% (14/15), and 100% (12/12) respectively. DCV and ASV were well tolerated among the majority of patients and discontinuation of the treatment due to adverse events (hypertension, bradycardia, leukemia) was occurred in 3 patients. In two patients with indeterminate NS5A RAVs, one achieved SVR12 but the other showed viral breakthrough and discontinued treatment. Conclusions: In this study, DAV and ASV combination therapy for chronic hemodialysis patients with HCV infection achieved high sustained virological response with few adverse events. Close monitoring of safety and tolerability may be necessary when treating chronic hepatitis C patients with CRF receiving DCV and ASV.

To improve mechanical properties of Cu-Al-Ni alloy by the grain refinement, Cu-Al-Ni SMA ribbons were fabricated by melt spinning apparatus. The variations of microstructure, transformation characteristics and mechanical properties with wheel speed were investigated in Cu-Al-Ni SMA ribbons. The ribbons fabricated by melt spinning obtained around 1.5mm in width and 50∼60㎛ in thickness. With increasing wheel speed in order of 10m/s, 15m/s, 20m/s, 30m/s and 35m/s, the grain size was decreased in order of 10㎛, 6㎛, 5㎛, 3㎛ and 3㎛. M_(s) and A, temperatures were decreased with decreasing grain size By X-ray diffraction test, ordered β_1 phase was observed in all the SMA ribbons and the volume friction of it was increased with increasing wheel speed. With increasing wheel speed, strain was increased from 4.8% to 5.8% and fracture mode has changed from mixture of intergranular and dimple fracture to mixture of fiber structure and dimple fracture
