목적 : Astromicin은 aminoglycoside계 항생제와 유사한 화학구조와 특성을 지니고, 기존의 aminoglycoside와 유사하거나 향상된 임상효과 및 부작용을 지닌 것으로 알려져 있다. 저자들은 astromicin의 약동학적 특성을 분석하고, astromicin 투여 환자를 대상으로 한국인에서 그 임상적 및 세균학적 효과와 안전성을 평가하고자 하였다. 대상 및 방법 : 약동학적 지표는 정상성인 남자를 대상으로 astromicin 200㎎을 30분간 정주한 후 24시간까지 혈장 및 뇨 검체를 수집하여 one-compartment open model에 따라 분석하였다. 중증으 세균감염이 있는 18세 이상의 환자를 대상으로 병용 또는 단독 투여한 후 임상적 효과와 세균학적 효과를 판정하였고, 치료전과 후의 순음청력검사와 혈청 크레아티닌으로 이독성과 신독성을 평가하였다. 결과 : 정상 성인 남자 12명을 대상으로 약동학적 지표를 평가하였고, 최고혈장농도는 투여 종료시점(C_(0))에서 16.87±1.68㎍/mL였으며, 반감기는 1.86±0.43 시간 이었고, AUC_(0-12h)은 38.12±10.57㎍ㆍhr/mL, Vd는 0.18±0.02L/㎏, CL은 5.25±2.07L/hr였다. 이러한 약동학적 지표는 다른 aminoglycoside와 유사한 결과를 보였다. 59명의 환자를 대상으로 시행한 임상적 효과 분석에서는 단독요법을 시행한 50명 중 임상적 치유율 94%, 세균학적 치유율 100%를 보였고, 순음청력검사를 시행한 48례의 환자중 의미있는 청력감소 소견은 관찰되지 않았으며, 신독성 또한 전혀 나타나지 않았다. 결론 : Astromicin의 약동학적 지표는 다른 aminoglycoside의 약동학적 지표와 비슷한 양상을 보이므로 향후 astromicin의 약물농도 감시에 있어서 다른 aminoglycoside의 치료적 약물 농도 감시 방법과 유사한 방법을 적용할 수 있으리라 기대된다. 또한 임상적 치유율이 우수하면서 신독성이나 이독성이 적어 세균 감염 환자의 치료에 있어서 단독 또는 병합 요법으로 비교적 안전하게 사용할 수 있으리라 생각된다. Astromicin(Fortimicin®) has some characteristics in common with other aminioglycoside antibiotics, although it has a unique chemical structure, which is different from them. This study was performed to elucidate the pharmacokinetic (PK) parameters of astromicin following single-dose intravenous infusion of 200 mg and to evaluate clinical efficacy and safety of astromicin in Korean populations. PK parameters of astromicin were determined in 12 healthy volunteers (65.5±5.2㎏). The plasma and urine samples were collected up to 24hrs. PK variables were calculated by fitting individual concentration-time curves to a one-compartment open model. Plasma level at the end of infusion was 16.87?1.68 ㎍/mL and declined to 1.05±0.35 (㎍/mL 8hr later. The half-life was 1.86±0.43 hr. Apparent volume of distribution was 0.18±0.02 L/㎏g, and total body clearance was 5.25±2.07 L/hr. These values were similar to those of other aminioglycosides. Clinical efficacy and safety were eviuated in 59 patients with moderate to severe bacterial infections who needed parenteral antibiotics. Among 50 patients who recieved astromicin monotherapy, 49 (98%) had favorable clinical reponse and 28 (100%) had favorable bacteriological response. Serial audiograms revealed no change in all of 48 patients. No nephrotoxicity was observed in all patients. Conclusively, our data suggest that therapeutic drug monitoring of astromicin can be conducted in a similar fashion as other aminioglycosides and astromicin is a useful and safe antibiotic in the treatment of severe bacterial infections.

The purpose of this study was to determine the changes in body composition, cardiopulmonary function, and flexibility following 8 weeks' bicycle ergometer exercise training. The subjects of this research consisted of healthy adult women between 30 and 40 years of age. Initial intensity of bicycle ergometer exercise was based on the target heart rate equivalent to 55% of maximal oxygen uptake, and intensity of the exercise increased by 5% every 2 weeks. Body composition, cardiopulmonary function at rest and during maximal exercise, as well as flexibility were determined before and after 8 weeks of bicycle ergometer exercise training. Masimal exercise was performed on the treadmill according to Bruce Protocol. The results obtained were as follows; 1. There were o changes in body weight, percent body fat, fat body weight, and lean body weight as well. The ventilation volume for 1 minute, respiratory quotient and expired CO₂ volume have not changed significantly after the training, either. 2. As a result of training, resting systolic and diastolic blood pressure decreased significantly(p<.05) 3. Maximal heart rate, maximal oxygen consumption and maximal running time increased significantly after the training(p<.05) 4. Pelvic flexibility increased slightly after the training, however, it did not reach the statistical significance. Trunk flexion forward increased significantly after the training(p<.05). From these results, it may be concluded that 8 weeks bicycle ergometr training improve the cardiopulmonary function and flexibility in healthy adult women between 30-40 years of age.

흰쥐 십이지장 점막의 Polyamine 대사, [^(14)C]Spermine 단백 결합능 및 [³H]Thymidine DNA 섭취에 대한 Calcitriol과 Prednisolone의 상호작용

최상현,이영재,정휘정,김형건,신경호,천연숙,전보권 고려대학교 의과대학 1997 고려대 의대 잡지 Vol.34 No.1

Calcitriol has been shown to induce the duodenal synthesis of the spermine-binding protein. and hydrocortisone was reported to increase the intestinal polyamine contents. This study examined whether prednisolone might enhance or reduce the calcitriol effects on the polyamine contents, [^(14)C]spermine-protein binding activity, and [^(3)H] thymidine DNA synthesis of the rat duodenum. The mucosal contents of putrescine. spermidine. and spermine were increased by 198.8%, 84.0%, and 78.3%, respectively, within 6 hours after calcitriol. 5 ㎍/kg (CT) and fell down to the control values at 12 hours. And prednisolone. 10 mg/kg (PD) also increased the polyamine contents in similar patterns. They did not counteract each other in the polyamine metabolism. CT increased the [^(14)C]spermine-binding activity of the cytosol protein fraction from the duodenal mucosa by 71.1%. But PD increased the binding activity by 28.0% and did not affect the CT-induced increase. CT increased the [^(3)H]thymidine DNA synthesis of the duodenal mucosa by 42.3%. but PD reduced it slightly. The CT-dependent increase of the synthesis was significantly inhibited by PD. These results suggested that the inhibitory effect of glucocorticoids on the vitamin D dependent increases of the duodenal calcium absorption and mucosal proliferation seems not to be associated with the metabolic changes of polyamines in the duodenal mucosa.

The pharmacodynamic mechanisms of available antidepressant drugs have not yet clarified. Major depression is common and may more frequently occur for the first time in the eldery, and the incidence of thromboembolism is increased with advancing of age. And many studies have shown an usefulness of platelet as models of monoaminergic neurons. Therefore, this paper. deals with the anti-platelet activity of antidepressant drugs in view of the common action in platelet signal-transduction system of three antidepressants showing different modes of action. The IC_(50)s of amitriptyline alprazolam. and rolipram were 1.39×10^(-4), 2.63×10^(-4), and 8.11×10^(-4)M. respectively, and that of each of the reference drugs : sodium nitroprusside. chlorpromazine. and spermine were 1.26×10^(-6), 5.76×10^(-5) and 4.28 ×10^(-3)M. Rolipram and alprazolam produced the significant increase of platelet cGMP level with slight cAMP increase. showing their selectivity on typeⅡ cGMP-specific PDE. Spermine and antidepressants, particularly used in this study induced the marked increase of platelet IP_(3) level with the anti-platelet and [Ca^(++)]_(i),-decreasing activities. These findings suggest that the mechanism of action of antidepressant drugs seems to be related with their enhancing property of the neuronal IP_(3)-mediated signalling. and that the paradoxical mode of their actions on platelet metabolisms of [Ca^(++)]_(i) and IP_(3) may be a clue of the uncovering of a new cellular [Ca^(++)]_(i)-regulating mode.

The study examaines characteristics of hair in order to provide costumers with satisfactory services. The subjects of this study were 297 women who were 21 to 40 years old or who were students at the Department of Beauty Design in Kyungbuk Province. A questionnaire was distributed to each woman. The results of this study can be summarized as follow. 1. The groups of self-businessmen, beauty designers, and make-up artists showed higher rate of straight hair than the other groups. 70.4% of the self-businessmen had straight hair and 51.5% of the beauty designers and make-up artists had straight hair(p<0.05). In the case of monthly income, 55.8% of the respondents whose income was above two million and four hundred thousand won had straight hair(p<0.05). The rate of having straight hair was high in the group of higher income. 2. According to hair types by the variables of health and stress, 72.2% of the respondents, who thought that they were in good health, had straight hair. 65.1% of them, who thought that they were in bad health, had curly hair (p<0.05). 48.3% of the respondents who did not get stress easily had straight hair, while 55.7% of them who got stress easily had curly hair. There was no significant difference between the two groups. 3. In the case of hair types by physical and mental characteristics, 27.1% of the respondents who possessed earth and wind characteristics' had straight hair. 66.2% of the respondents who possessed wind characteristic' had curly hair and 62.5% of them who possessed earth, fire, and wind characteristics' had curly hair. 70.0% of the respondents who possessed very strong endurance had curly hair. 4. 45.6% of the respondents whose hair was black had straight hair. 53.7% of them whose hair was brown had curly hair. 61.7% of dry hair was curly hair, while 55.4% of normal hair was straight hair (p<0.001). 5. 37.8% of the respondents who had 11% to 20% of white hair responded that their hair was thick. 57.8% of them who had 1% to 10% of white hair replied that their hair was normal. 32.5% of them who had 0% of white hair answered that their hair was thin (p<0.001). The thicker their hair was, the more they had white hair. 24.0% of them who got a lot of stress had thick hair. while 67.6% of them had normal hair. 44.8% of them who did not get stress had thin hair (p<0.01). 6. 23.6% of black hair was thick and 57.4% of brown hair was common. 39.3% of yellowish brown hair was thin (p<0.05). The thicker their hair was, the more their hair was black. The thinner their hair was, the more their hair was yellowish brown. 18.7% of normal hair was thick and 64.1% of normal hair was common. 35.8% of dry hair was thin (p<0.01). The thicker their hair was, the more normal hair was. The thinner their hair was, the more dry hair was. The hair related factors were different according to the variables of health status, endurance, characteristics of hair, occupation, and income level. Therefore, hair designers can provide better services by recognizing characteristics of hair and customers' psychological needs.

최상현,문창택,민본홍,전보권,천연숙 고려대학교 의과대학 1992 고려대 의대 잡지 Vol.29 No.3

The influences of spermine (SM) and DFMO. an irreversible ODC-inhibitor, on the polyamine metabolism, CK-activity, [^(3)H]-thymidine DNA synthesis, and isoactin mRNA expression of BC_(3)H1 in culture were studied, with the references of phosphodiesterase(PDE)-inhibitors including isobutyl-methylxanthine (IBMX) and KR30075. BC_(3)Hl cells cultured in 10% fetal bovine serum (FBS)-DMEM for 24 hrs (the first : pre-drug phase) were cultivated in 10% FBS-DMEM added with one of the test drugs for further 96 hrs(the second proliferation phase), and then continue to grow in 2% FBS-DMEM for 48 hrs (the third : differentiation phase). The putrescine content of BC_(3)Hl harvested after the first phase was relatively higher in comparison with those of the other phases and was gradually decreased through the full phases of culture, and the spermine content was little changed. The spermidine (SD) content was. unlike other polyamines, increased by 26.5% at the end of the second phase, but that SD increase was moderately attenuated by PDE-inhibitors, particularly KR30075, and furthermore. the SD content of BC_(3)Hl cultured in the presence of DFMO, unlike other polyamines. showed the marked and gradual decrease throughout the full phases of culture. The [^(3)H]-thymidine DNA synthesis during the third : differentiation phase was not affected by IBMX and slightly inhibited by KR30075, but was significantly inhibited by SM plus DFMO or each of them. And the creatine kinase (CK) activity gradually increased in advancing with culture duration was not changed by PDE-inhibitors. but both SM and DFMO significantly enhanced the increase of CK activity. The synthesis of BC_(3)Hl α-actin and β-/ γ-actin mRNAs was significantly enhaced by DFMO, and the DFMO-induced enhancement was dramatically inhibited by SM. And PDE-inhibitors and SM little affected the synthesis of α-actin mRNA, but PDE-inhibitors attenuated the synthesis of β-/ γ-mRNAs, especially in the second phase. These results suggest that polyamines have a pivotal role in the proliferation and differentiation of BC_(3)Hl cells, that the enhancement induced by DFMO of expression of VSM isoactin gene seems to be an attractive subject to be studied in future, and that PDE-inhibitors may inhibit the synthesis of VSM β-/ γ-actin mRNAs.

김연숙,최영실,오원섭,권기태,이혁,이선희,손준성,김신우,장현하,정숙인,고관수,박미연,백경란,송재훈 대한감염학회 2006 감염과 화학요법 Vol.38 No.6

배경 : 2002년 내국인에서의 첫 사람 브루셀라증의 증례 보고 이후 국내에서 사람 브루셀라증이 빠른 증가를 보이고 있다. 이에 연구자들은 국내에서 발생하는 브루셀라증의 임상적 특성을 연구하고자 하였다. 방법 : 2003년부터 2006년 7월까지 7개 대학병원에 내원한 환자들을 대상으로 WHO의 진단기준에 의하여 확진된 브루셀라증 환자들의 의무기록을 후향적으로 조사분석 하였다. 배양된 균은 삼성서울병원에 의뢰하여 16S rRNA 유전자 분석방법을 이용하여 종을 확인하였고, 표준시험관응집검사는 국립보건원에 의뢰하여 시행하였다. 결과 : 34예의 환자들이 브루셀라증으로 확진되었고, 31명이 남자였다. 혈액에서 B. abortus가 증명된 경우가 8예, 표준시험관 응집검사상 의미 있는 항체가 상승을 보인경우가 26예이었다. 환자들은 대부분 축산업관련 종사자였고, 추후 브루셀라증으로 확진된 소와의 직접 접촉을 통해 감염된 것으로 여겨진다. 국내 사람 브루셀라증의 가장 흔한 증상은 발열이었고, 위장관계 합병증이 가장 흔히 동반되었다. 치료로는 doxycycline/rifampicin이 24예의 환자에서 doxycycline/aminoglycoside (streptomycin 혹은 gentamicin)이 10예의 환자에서 6주 이상의 기간 동안 투여되었다. 치료에 반응을 보이지 않는 환자는 없었고, 재발이 1예 있었다. 결론 : 국내에서 발생하는 사람 브루셀라증의 원인균으로 현재까지 분리 동정된 것은 B. abortus이며, 소 브루셀라증의 증가로 인해 인체감염사례가 함께 증가하는 것으로 사료된다. 위험 직업군 종사자들에서 감염된 소와의 직접 접촉을 통해 주로 발생하고 있는 브루셀라증의 임상종상은 국외에서 발생하는 경우와 유사한 양상을 보이고 있으며 치료에 대한 반응은 비교적 좋은 편이긴 하나, 추후 보다 많은 환자들을 대상으로 한 연구가 필요하리라 사료된다. 사람 브루셀라증의 조절을 위해서는 소 브루셀라증의 조절이 필수적이며, 브루셀라증의 조절에 성공한 선진국의 사례를 적극적으로 도입해야 할 것으로 생각된다. Background : Since the first Korean case of human brucellosis was reported in 2002, the incidence of human brucellosis has been rapidly increasing. We performed this study to evaluate the clinical characteristics of human brucellosis occurring in South Korea. Materials and Methods : Demographic features, clinical manifestations, and therapeutic outcomes of cases confirmed as brucellosis according to WHO diagnostic criteria were evaluated. Species of Brucella isolates were identified with 16S rRNA gene sequencing method. Serologic diagnosis was performed with standard tube agglutination test (STA). Results : A total of 34 cases were enrolled from 2003 to 2006 in six hospitals. Eight cases were confirmed with the isolation of Brucella from blood and 26 cases were confirmed with titer of antibodies ≥1:160 by STA. Male (31) was predominant and most of the patients were cattle farmers. The most common transmission route was direct contact with infected or their cattle byproducts. Fever was the most prominent symptom and fatigue followed. Gastrointestinal and musculoskeletal systems were commonly complicated. Patients were treated with doxycycline and rifampin or aminoglycosides for more than 6 weeks. All patients responded well to the therapeutic regimens, but one patient relapsed 10 months after treatment. Conclusion : Brucellosis occurring in Korea has been caused by B. abortus, whose preferred natural host animals are cattle. Korean patients were infected through direct contact with bovine brucellosis. Clinical manifestations of brucellosis were similar to those occurring worldwide. Therapeutic outcomes were good among patients with brucellosis in Korea. In order to prevent human brucellosis, measures to eradicate bovine brucellosis should precede.
