연구목적 : 본 다기관 공동임상연구는 국내 환자를 대상으로 새로운 항정신병약물인 올라자핀의 치료 효과와 안전성을 확인하고자 시행되었다. 방 법 : 1999년 7월부터 2000년 3월까지 국내 10개 병원에 방문한 정신분열병 및 정신분열형 장애 105명을 대상으로 비대조 개방 임상연구를 시행하였다. 중등도 이상의 정신병 증상을 지니거나, 부작용으로 약물교체가 필요한 경우 또는 기분장애 증상의 치료가 필요한 환자를 대상으로 하였다. 2∼7일간의 약물 배설기간 후에 1일 10mg의 올란자핀을 투여하였고, 이후로 3∼7일 간격으로 용량을 조절하여 총 8주간 투여하였다. 치료 효과는 PANSS(Positive and Negative Syndrome Scale), BPRS(Brief Psychiatric Rating Scale), CGI(Clinical Global Impression-Severity), MADRS(Montgomery-Asberg Depression Rating Scale), HAM-A(Hamilton Rating Scale for Anxiety)로 판정하였다. 안전성 평가는 자발적인 이상반응 보고, 활력징후와 혈액 검사 및 SAS(Simpson-Angus Scale), BARS(Barnes Akathisia Rating Scale), AIMS(Abnormal Involuntary Movement Scale)척도를 이용하였다. 결 과 : 105명중에서 85.7%인 90명이 8주간의 치료를 완료하였다. 평균 최빈 용량은 일일 16.1(±4.7)mg이었고, 종료시점에서의 BPRS전체 점수가 기저 상태에 비해 40%이상 감소된 반응군은 69.5%이었다. PANSS의 양성 증후군과 일반정신병리 뿐만 아니라 음성 증후군 소척도에서도 유의한 감소를 보였으며, 이 감소들은 치료 초기부터 나타나서 8주간 지속되었다. 43.8%의 피험자가 중등도 이상의 우울증상을 같이 지니고 있었으며, 올란자핀에 의해 MADRS와 HAM-A가 유의하게 감소하였다. 치료 기간 동안에 활력징후에는 뚜렷한 변화가 없었으나 체중은 8주간 지속적으로 증가하였다. SAS와 AIMS는 감소하였으며, 정좌불능증을 제외한 나머지 추체외로 증상의 발생비율도 낮았다. 임상적인 증상이나 징후를 동반하지 않는 ALT/SGPT의 상승을 보였지만 프로락틴을 포함하는 대부분의 혈액 검사상 뚜렷한 이상 변화는 없었다. 결 론 ; 비록 본 임상연구가 비대조 개방 임상연구로서 많은 제한점을 가지고 있지만, 올란자핀이 기존 약물에 내약성을 보이거나 기분증상을 동반하는 정신병에 치료 효과가 있었다. 그리고 기존 항정신병약물 치료시에 문제가 되었던 추체외로 증상과 고프르로락틴 혈증을 포함하는 대부분의 부작용면에서 안전성을 보여 주었다. Objective : This multicenter clinical trial was carried out to investigate the efficacy and the safety of olanzpine for the treatment of Korean patients. Mothod : 105 patients with schizophrenia and schizophreniform disorder, visited at 10 mental or university hospitals, had received an open and non-comparative treatment with olanzapine for 8 weeks. Patients had psychotic or depressive symptoms with the severity above moderate degree or intolerable side effects to previous antipsychotics. After a wash-out period of 2-7 days, 10mg olanzapine was prescribed initially to all the patients, and then the dosage could be adjusted within the range of 5-20mg/day of olanzapine by 3-7 days. Results : 90(85.7%) of 105 patients completed the 8-weeks trial and the mean modal dose of olanzapine was 16.1(±4.7%)mg/day. At the end of the trial, 73 patients(69.5%) were classified as responder, which was defined as 40% or more improvement in BPRS(Brief Psychiatric Rating Scale) score comparing to baseline. There was a significant reduction in the scores of PANSS(Positive and Negative Syndrome Scale)and subscales including negative symptom scores and CGI. Also weekly analysis showed that the reductions in scores were kept on for the whole period of the trial. 43.8% of all the patients had depressive symptoms at the baseline and total scores of MADRS(Montgomery-Asberg Depression Rating Scale) and HAM-A(Hamilton Rating Scale for Anxiety) were also reduced after the trials. Vital signs revealed no clinically significant changes but continuous weight gain was observed during the treatment with olanzapine. The scores of SAS(Simpson-Angus Scale) and AIMS(Abnormal Involuntary Movement Scale) for assessing the EPS(extrapyramidal symptoms)and tardive dyskinesia respectively were significantly decreased and only a few patients reported EPS as adverse events. Although mild and clinically non-significant of ALT/SGPT was observed, most laboratory parameters including plasma prolactin level showed to significant changes during the trial. Conclusions : Although this trial had many limitations because it was a non-comparative and open study, olanzapine showed high efficacy on the positive, negative and depressive symptoms in schizophrenia and schizophreniform disorder.In addition to that, olanzapine showed a substantially favorable safety profile, such as low incidence of EPS and hyperprolactinemia.

Background: The purpose of this study was to document the incidence and clinical characteristics of patients with tuberculosis (TB) in combat and auxiliary police, living in a group, in Korea where the incidence rate of active TB in a general population is higher than in Western countries. Materials and Methods:We retrospectively reviewed the medical records of all tuberculosis patients diagnosed at National Police Hospital from January 2002 through December 2004. Results:In 2002-2004, a total of 156 cases of tuberculosis were identified with the mean (Standard deviation) age of 20.6 (±1.0) years. Of these, 134 (85.9%) patients were registered as new cases, 11 (7.1%) as relapse, 2 (1.3%) as failure, 5 (3.1%) as treatment-after-default cases whereas 4 (2.6 %) patients were not included in any categories. Average annual new TB rate and smear-positive TB rate were 86.5/10^(5) and 17.4/10^(5) person-years, respectively. In 12 of 31 smear-positive cases, time from onset of symptoms to diagnosis was more than 30 days. Two multidrug-resistance TB cases were identified and two suspected outbreak episodes of TB had occurred during 3 years. Conclusion:There was no statistically significant difference in the incidence rate of new cases of TB between the general population aged 20 to 29 years and combat and auxiliary police in Korea. 배경 : 국내 결핵의 발생은 감소 추세에 있으나 여전히 후진국형 발생양상을 보이고 있다. 특히 집단생활을 하는 젊은이들에서 발생하는 결핵의 유행이 간헐적으로 알려지고 있어 우려를 낳고 있다. 이에 저자들은 최근 전경대원의 결핵 발병 양상에 대해 알아보고자 본 연구를 시행하였다. 재료 및 방법 : 2002년 1월부터 2004년 12월까지 3년간 경찰병원에서 결핵 진료를 받은 전경대원의 의무기록을 후향적으로 분석하여 연도별 결핵 신환발생률, 도말양성결핵 신환율, 진단 지연, 집단발병, 다제내성결핵을 조사하였다. 결과 : 연도별 결핵 신환자 수(10만명당 발생추정치)는 2002년 50명(83.6명), 2003년 42명(83.7명), 2004년 42명(93.5명)이었고 도말양성 폐결핵 신환자 수는 2002년 10명(16.7명), 2003년 11명(21.9명), 2004년 6명(13.4명)이었다. 3년간 도말양성 폐결핵 환자는 31명이 있었고 그 중 12명은 호흡기 증상 발생 30일이 지나서 진단을 받았다. 다제내성 결핵은 2명이 있었으며 결핵의 집단발병이 의심되는 사례는 2차례 있었다. 결론 : 전경대원과 20-29세 연령군 일반인의 결핵 신환발생률, 도말양성 폐결핵 발생률의 통계적으로 유의한 차이는 없었다.

토란의 기지 shoot를 암배양하여 절간이 신장한 황하경을 얻고 이황하경의 절편을 계대배양하여 기내증식을 시도하였다. 황하경은 NAA 0.2mg/ℓ가 첨가된 배지에서 가장 길게 신장하였다. 황하경은 자구형성형이 모구배대형보다 길게 신장하였다. 호르몬이 첨가된 거의 모든 배지에서 protocorm이 형성되었으나 0.2mg/ℓ NAA + 0.2mg/ℓ BA를 첨가한 배지에서 특히 많이 형성되었고 이 protocorm을 MS기본 배지에 옮겼을 때 8.5%의 재분화율을 보였다. Etiolated stems with elongated internodes were obtained from the in vitro culture of shoots of Colocasia esculenta schout under dark condition and plant differntiation was achived by subculturing the ethiolated stem segments. The etiolated stems elongates better on the media containing 0.2mg/ℓNAA than of those lacking it. Subculture of the etiolated stem segments produced protocorm-like structures in all the media examined. The medium containing 0.2mg/ℓNAA and 0.2mg/ℓBA produced the higest number of protocorm-like structure, which regenerated into plantets at 85% when transferred to phytohormone-free MS medium.

목적 : 제일제당에서는 녹농균의 세포외막 단밸질을 유효성분으로 하는 백신인 CFC-101을 개발하였으며, 동물시험에서 이 백신의 안전성과 유효성을 입증하였다. 본 연구에서는 이 녹농균 백신의 인체에 대한 안전성과 면역원성을 평가하는 동시에 인체 접종시의 최적 투여 용량을 결정하기 위하여 제 I/Ⅱa상 임상시험을 수행하였다. 방법 : 건강한 성인 남자를 피험자로 선별하여 각 용량군에 백신투여자 6명, 위약투여자 2명을 배정하였다. 백신 투여군은 0.25mg, 0.5mg 또는 1.0mg 용량의 녹농균 백신을 7일 간격으로 3회에 걸쳐 근육주사 하였으며, 위약 투여군에게는 세포외막 단백질을 제외한 동일한 성분을 투여하였다. 백신접종 후 국소적 또는 전신적인 반응의 발생여부를 관찰하고, 혈액시료를 체취하여 백신의 역가와 유효성을 검정하였다. 결과 : 녹농균 백신 CFC-101은 모든 접종자에서 양호한 내약성을 보였다. 또한 0.5mg 과 1.0mg 백신 투여군에서는 100%의 항체양전율을 나타내었다. 생성된 항체는 녹농균 세포외막단백질에 특이성을 보였고, 녹농균 감염에 대해 방어효능이 있었다. 결론 : 이와같은 결과로부터 이 녹농균 백신은 인체에 안전하게 투여할 수 있으며, 높은 항체 생성능으로 감염방어 효능을 보이고 0.5mg과 1.0mg이 최적용량인 것으로 판단되었다. Background : We developed a Pseudomonas aeruginosa outer membrane protein(OMP) vaccine CFC-101, and the prophylactic efficacy of which has been demonstrated in animal models. In order to evaluate the safety and immunogenicity of the P. aeruginosa vaccine, we carried out a phase I/Ⅱa clinical trial in healthy male volunteers. Methods : Groups of eight volunteers, including two placebo subjects, were vaccinated intramuscularly with three doses of 0.25, 0.5 or 1.0 mg of the vaccine at one week intervals. Sings of systemic and local reactions observed after vaccination were recorded for each vaccinee for 5 days. Physical examinations were performed on days 0, 1, 7, 8, 14, 15, 21, and 42, and clinical laboratory tests were done on days 0, 3, and 21. Blood samples for assay of serum antibody levels were obtained up to 42 days after the first vaccination. Results : The vaccine was generally well tolerated by all vaccinees, showing no significant side effects. In the three dosage groups, all vaccinees, except one receiving the 0.25 mg dose, showed significant elevation in serum IgG antibody titers against the vaccine proteins, indicating 100% seroconversion in 0.5 and 1.0 mg groups. The human antibodies induced by the vaccine were specific for P. aeruginosa OMPs, as confirmed by western blot analysis and immunoprecipitation assays. The capacity of the human antisera to enhance opsonophagocytic killing activity by polymorphonuclear leukocytes and to confer protection against P. aeruginosa infections indicates that the antibodies elicited by the vaccine have protective efficacy. Conclusion : We conclude that the P. aeruginosa OMP vaccine is safe and effective for human use and its optimal dose to be 0.5 or 1.0 mg.

Hyun Hwangbo,Da He Kwon,Eun Ok Choi,Min Yeong Kim,Kyu Im Ahn,Seon Yeong Ji,Jong Sik Kim,Kyung-Il Kim,No-Jin Park,Bum Hoi Kim,Gi-Young Kim,Su-Hyun Hong,Cheol Park,Ji-Suk Jeong,Yung Hyun Choi 대한지역사회영양학회 2018 Nutrition Research and Practice Vol.12 No.5

BACKGROUND/OBJECTIVES: Benign prostatic hypertrophy (BPH) is a major cause of abnormal overgrowth of the prostate mainly in the elderly. Corni Fructus has been reported to be effective in the prevention and treatment of various diseases because of its strong antioxidant effect, but its efficacy against BPH is not yet known. This study was designed to evaluate the therapeutic efficacy of Corni Fructus water extract (CF) in testosterone-induced BPH rats. MATERIALS/METHODS: To induce BPH, rats were intraperitoneal injected with testosterone propionate (TP). Rats in the treatment group were orally administered with CF with TP injection, and finasteride, which is a selective inhibitor of 5α-reductase type 2, was used as a positive control. RESULTS: Our results showed that the increased prostate weight and histopathological changes in BPH model rats were suppressed by CF treatment. CF, similar to the finasteride-treated group, decreased the levels of testosterone and dihydrotestosterone by TP treatment in the serum, and it also reduced 5α-reductase expression and concentration in prostate tissue and serum, respectively. In addition, CF significantly blocked the expression of the androgen receptor (AR), AR co-activators, and proliferating cell nuclear antigen in BPH rats, and this blocking was associated with a decrease in prostate-specific antigen levels in serum and prostate tissue. CONCLUSIONS: These results suggest that CF may weaken the BPH status through the inactivation of at least 5α-reductase and AR activity and may be useful for the clinical treatment of BPH.

안현경(Ahn Hyun-Kyoung),이인형(Rhee In-Hyoung),정현준(Jeong Hyun-Jun),박병기(Park, Byung-Gi) 한국산학기술학회 2008 한국산학기술학회논문지 Vol.9 No.6

PWR 정지화학 조건에서 모사실험하여 니켈페라이트 입자의 거동을 조사하였다. 농도가 Li 0.1 ppm, B 2000 ppm인 모사실험 용액의 온도는 300 ℃에서 0.625 ℃/min의 비율로 150 ℃까지 감소시킨 후 일정 시간 동안 150 ℃를 유지하였고 이때의 압력은 2500psi 이하로 유지하였다. 수소 농도 5, 15, 25 cc/㎏ H₂O 일 때 온라인으로 입자 분포를 측정하였고 용해된 니켈 농도도 분석하였다. 실험결과 온도 감소 시 세 가지 수소 농도일 때 모두 총 입자 수는 큰 변화가 없었다. 그러나 온도가 감소하고 일정하게 유지될 때 입자는 작아졌다. 입자 크기 분포 변화의 정도는 H₂ 15cc/㎏ H₂O 일 때가 가장 크게 나타났다. 니켈 이온의 농도는 온도가 감소하고 수소 15 cc/㎏ H₂O 일 때 증가하였다. 이 결과 니켈 페라이트는 온도 변화 시, 수소 15 cc㎏ H₂O 일 때 불안정 한 것으로 보여 진다. The particulate behaviors of nickel ferrite were investigated under the simulated PWR shutdown chemistry conditions. Temperature of the simulated water with concentration of 0.1 ppm Li and 2,000 ppm B was dropped from 300℃ to 150℃ with a rate of 0.625 ℃/min and then constantly maintained at 150℃ under the pressure of 2,500 psi. The on-line particle counting and the concentration measurement of nickel dissolved were performed under 5, 15 and 25 cc/㎏ H₂O dissolved hydrogen. Experimental results showed that total particle count in the simulated water was not greatly changed for three hydrogen concentrations as temperature was decreased. However, particles were smaller as temperature was decreased and then maintained constantly. The degree of variation in particle size distribution was greater at 15 cc/㎏ H₂O dissolved hydrogen than any other dissolved hydrogen concentrations. Concentration of nickel ion was increased as temperature was decreased and was higher at 15 cc/kg H₂O dissolved hydrogen than any other dissolved hydrogen concentrations. Theses results show that nickel ferrite is unstable with temperature variation and at dissolved hydrogen concentration of 15 cc/㎏ H₂O.

A comparison study of the effects of loratadine-pharmacopuncture and loratadine-oral administration based on traditional Korean medicine theory on anaphylactic reaction in mice

Kim, Hyun-Min,Kim, Hyun-Min,Lee, Min-Jung,Cho, Min-Gi,Kang, Deok,Kim, Yu-Kyung,Kim, Changmin,Kang, Do-Hyun,Jeong, Si-Hwa,Ahn, Ik-Gyun,Hwang, Jun-Hyeok,Kim, Jae-Hyun,Lee, Hyun-Jin,Jang, Jun-Yeong,Park, Cellmed Orthocellular Medicine and Pharmaceutical 2018 셀메드 (CellMed) Vol.8 No.1

Pharmacopuncture, or herbal acupuncture, is a new form of therapy derived from combinations of two traditional therapeutic methods, herbal medicine and acupuncture therapy. To compare the efficacy between loratadine-pharmacopuncture (LP) and loratadine-oral administration (LO), the effect of loratadine was investigated in murine models. Anti-anaphylactic effects of loratadine treatments were investigated in compound 48/80-induced systemic anaphylactic reaction and passive cutaneous anaphylaxis (PCA). LP treatment significantly inhibited the compound 48/80-induced systemic anaphylactic reaction and PCA. The effect between LP and LO were on a similar level. These results indicate that LP can be used as an alternative method for LO in case of emergency.
