목적 : 국내에서 발열을 동반한 호중구감소증이 있는 악성 종양환자에게 경험적 항생제로 베타락탐계 항생제와 아미노배당체의 병합요법의 사용이 일반적이다. Cefepime은 광범위 항균 작용을 가지고 있어, 그람 음성균 뿐만 아니라 그람 양성균에 대해서도 우수한 효과를 나타낸다. 재료 및 방법: 발열을 동반한 호중구감소증이 있는 악성 종양환자를 대상으로 무작위, 공개, 비교 연구를 시행하였다. 대상 환자를 무작위로 cefepime 단독요법군과 ceftazidime 및 tobramycin 병합요법군으로 나누어 투여하고 각각의 임상적 효능과 안전성을 비교하였다. 구강및 인후 점막염이 있는 환자에서 분리된 녹색 연쇄알 구균에 대한 항생제 내성 정도를 조사하였다. 결과 : 대상환자 89명 중 CA 투여군이 48예(53.9%), CT 투여군이 41예(46.1%)이었다. 발열의 유형별로 MDI는 18예(20.2%), CDI는 9예(10.1%), UF는 62예(69.7%)로 두 군 간에 차이가 없었다. CA 투여군과 CT 투여군의 임상적 호전률은 시험약 투여 후 2-4일째 각각 91.7%, 85.4% (P=0.31), 치료 종료 시 각각 91.7%, 100% (P=0.15)로 두 군간에 유의한 차이가 없었다. 치료 종료 시 CA 투여군과 CT 투여군의 세균학적 소실률은 모두 100%로 두 군간의 유의한 차이가 없었다(P=0.78). 점막염이 있는 환자로부터 녹색 연쇄알 구균이 분리된 경우는 25예(28.1%)이었으며, 분리된 녹색 연쇄알 구균은 penicillin, ceftriaxone, cefepime, vancomycin에 모두 감수성을 보였다. 약제 관련 이상 반응의 발생 빈도도 두 군간에 유의한 차이가 없었다. 결론 : 발열을 동반한 호중구감소증이 있는 악성 종양환자의 경험적 항생제로서 cefepime 단독요법은 ceftazidime 및 아미노배당체의 병합요법만큼 효과적이고 안전하였다. Background : Broad-spectrum antibiotic therapy has been recommended as an empirical regimen in cancer patients with febrile neutropenia. Cefepime is a fourth generation cephalosporin with good activity against both gram-positive cocci and gram-negative bacilli. Materials and Methods : To compare the efficacy and safety of cefepime alone with ceftazidime plus tobramycin as empirical regimen for adult cancer patients with febrile neutropenia, a randomized, open label, comparative trial was performed. If the patient showed clinical improvent 72 hours, antibiotic could be changed to oral ciprofloxacin. Clinical and microbiological responses were determined at 72 hours and at the end of therapy. To investigate the antimicrobial resistance of viridans streptococci, swab cultures were obtained from throat in all enrolled patients and antimicrobial susceptibility tests were performed by using microdilution method according to the NCCLS. Results : A total of 89 patients were enrolled. Forty-eight patients received cefepime alone (CA), and 41 patients received ceftazidime plus tobramycin (CT). Demographic and baseline clinical characteristics were similar in both groups (P>0.05). The initial clinical success rate at day 2-4 in group CA (91.7%) was similar with that in CT group (85.4%) (P=0.31). At the end of therapy, the final clinical success rate in CA group (91.7%) was similar to that in CT group (100%) (P=0.15). In 18 patients, with microbiologically defined infections, the eradication rate was 100% in both groups. Adverse events including liver dysfunction (21.3%) and renal dysfunction (2.2%), were similar in both groups (P=0.87). Viridans streptococci were isolated from the throat cultures in 25 cases, and all of these strains were susceptible to penicillin (MIC_(90) 0.12 ㎍/mL), cefepime (1 ㎍/mL), and vancomycin (0.12 ㎍/mL). Conclusion : Efficacy and safety of cefepime monotherapy was comparable to the combination of ceftazidime and tobramycin. It could be used as an alternative empirical regimen for treating cancer patients with febrile neutropenia.

채희용 ; 이현기 김천대학교 1998 김천대학교 논문집 Vol.19 No.-

In 1990's, it is often supposed that the new trend of various distribution business is price destruction. The meaning of price destruction, here is not a price sale selling a discounted material during regular terms but the form of selling as a dramatically discounted price everyday and no holiday. Such new store types as discount stores of price destruction have begun to appear in Korean retailing market since November 1993. Since then, they have been growing very rapidly. Having led by a few department stores, supermarkets and conventional markets, the domestic retail arena met a meaningful turning-point with the rising number of discount stores. Cashing on their cutting edge. "so-good' price, to the extent of destructing the existing price structure and marketing structure as well, the discount stores are forecast to gain a rapid growth in coming years, leading the distribution industry expansion. This study focuses on the "low-cost operations” since the factor is the very reason for the creation and survival of discount stores and plays a decisive role in their success and failure. The competitiveness of discount stores will depend on how they effectively combine the low-cost operations and the marketing strategies, and give much satisfaction to consumers. The domestic retail picture will be re-drawn by a few strong play living up to these qualifications.

Five elements motion and six kinds of natural factors influence not only human disease but also difference of medicine effect. Because the climate of summer is very hot, that is easy to increase the properties of hot medicines, a doctor must be careful to use it in summer. Also the climate of winter is very cold, that is easy to increase the properties of cold medicines, a doctor must be careful to use it in winter. But in the certain conditions to use diaphoretics or purgatives, in spite of that regulation a doctor can use them.

이현국,양남웅,서재홍 朝鮮大學校 附設 醫學硏究所 1992 The Medical Journal of Chosun University Vol.17 No.1

In order to investigate the effect of trypsin(TP) on the phage antigenicity, the Klebsiella phage-host cell system and sheep red blood cells were used, and the results were as follows. The neutralization velocity of Tp-treated phage(Tp phage) by anti-normal phage serum was faster than that of normal phage. And, the neutralization of normal phage by anti-Tp phage serum was remarkably worse than that of Tp phage. The normal phage - neutralizing activity of the anti-normal phage serum absorbed with Tp phage was very weak. However, the anti-Tp phage serum absorbed with normal phage still considerably neutralized the Tp phage. The cold phage hemagglutination(CPH) by normal and Tp phage was most favourable when the reactions are carried out with each phage-correspondig antiserum. The anti-normal phage serum absorbed with Tp phage and the anti-Tp phage serum absorbed with normal phage still formed, with each corresponding phage, the CPH. The neutralization of Tp phage, by anti-normal phage serum, Passed two times through host bacteria and that of Tp phage, by anti-Tp phage serum, Passed three times through host bacteria were similar to the neutralization of normal phage by each antiserum. If the Tp phage is passed two times or three times through host bacteria, the forming capability of CPH by each phage bacame similar, under the anti - normal and anti - Tp phage sera, to that of normal phage. The absorption of Tp phage to host bacteria was a little faster than that of normal phage. If the Tp tretment of phage is done for 48hours at 37℃, the surviving titer was reduced to around 40%.

In this study, a system for the method measuring of passive electrical properties in the human body was developed. The system was composed of the stimulating part for input with voltage(about 2[㎷]) and of the measuring part for measurement of electrical properties in human body. As a result of this experiment, the frequency characteristic of each subject represent that the electrical properties goes up in spite of a constant stimulate-voltage according to frequency (l[㎐]-50[㎑]) increment. Namely, the amplitude of stimulate-signal was not reflected but frequency was reflected on the measured results. This result be estimated that the proposed system is able to measure the passive electrical properties of human body. Also, it would be estimated neural signal propagation directions by using the method developed in this study was measured passive electrical properties in each part of body.
