Test of Whole Body Recation Time (WBRT) is widely used as a measurement of agility on account of it's convenience and validity. In general, test value of WBRT is decided by a Mean value of five times' trials. However, the maximum expenditure of effort is essential for every test of WBRT. In this point of view, We have to find out the valid method for decision of the reliable value in WBRT test. For the purpose of this study, WBRT of 41 male athletes (17 soccer players, 21 rugby football player, and 3 tennis players) in college were measureed five times in a same day. And the mean of five times' trials (Real Mean : RM), mean of three times' trials except maximized and minimized value in five times (Trimmed Mean : TM), and maximized value in five times' trials were calculated and compared mutually. In addition to this, correlation among mean of each trials as test-retest reliability, paired t-test for the verification of difference among RM, TM, and MV, and Cronbach's Alpha for reliability of RM and TM were calculated by a computer. The results indicated that TM was more reliable than RM even though there was no significant difference in Mean. The greatest care must be taken in adoption of WBRT test value for any study, because there were significant differences between RM and MV, and TM and MV.

This work was accomplished with 6 day-old rye (Secale cereale L.) seedlings to determine the effect of the antibiotics by cycloheximide on in vivo nitrate reductase activity, protein and RNA content. The nitrate reductase activity by treating 0.1μM and 0.1 mM cycloheximide was lower than that of the control group. The optimum pH for the nitrate reductase of the control group was 7.6 in the range of pH 5.6-8.0, but, in the case of 0.1mM cycloheximide treatment group, the optimum pH was decreased to 6.8 within the weak the acid region. The protein content of shoot and root in the 0.1μM and 0.1 mM cycloheximide treatment groups were respectively found at the 96%, 82% level of that in the control group. In the higher cycloheximide treatment (0.1 mM CH), not only nitrate reductase activity and protein content but also RNA content was greatly decreased. In this fact, it was suggested that the 0.1 mM cycloheximide had affected on the RNA polymerase. On the basis of there results, it was concluded that the decreased nitrate reductase activity by treating cycloheximide occurred primarily according to the decreased nitrate uptake, and the decreased protein and RNA content depended upon the results of the direct and indirect effect of cycloheximide on the protein synthesis.

Background : The increasing incidence of multidrug-resistant gram-negative bacteria causing nosocomial infections is an important clinical problem. Isepamicin is a recently developed aminoglycoside which has been known to have potent activity against gram-negative organisms. We evaluated the in vitro activities of isepamicin and other aminoglycosides against a large number of gram-negative organisms. Materials and Methods : We tested the in vitro antimicrobial activities of isepamicin, amikacin, gentamicin, and tobramycin against 566 gram-negative organisms collected between January 2006 and June 2006 in Asan Medical Center. Minimal inhibitory concentrations (MICs) were determined and interpreted according to the recommendations of Clinical and Laboratory Standard Institute (CLSI). The breakpoint MIC used for interpretation of isepamicin was MIC≤16 ㎍/mL as susceptible, 32 ㎍/mL as intermediate, and 64 ㎍/mL as resistant. Results : The MIC_(50)/MIC_(90) of isepamicln for Escherichia coli, Klebsiella pneumon/ae, Pseudomonas aeruginosa, Acinetobacter baumannii, and Enterobacter cloacae were 1/2, 0.5/>128, 4/16, 16/>128, and 1/2 ㎍/mL, respectively. The susceptibilities for E. coli, K. pneumoniae, P. aeruginosa, A. baumannii, and E. cloacae were 100%, 86.4%, 89.7%, 50.0%, and 96.6%, respectively. For E. coli, K. pneumoniae, P. aeruginosa, and E. cloacae, isepamicln had better in vitro activities than gentamicin and tobromycin, and had similar activities with amlkacin. For A. baumanii, all four tested aminoglycosides had similar in vitro activities. Conclusion : Isepamicin had excellent in vitro activities against gram-negative organisms, except A. baumanii. The overall in vitro activities were similar with amikacin. 목적 : 그람 음성 세균은 다양한 지역사회 및 병원 획득 감염의 원인균이다. 최근에는 병원 감염을 일으키는 그람 음성 세균에서 항균제 내성균의 출현과 확산이 큰 문제가 되고 있다. Isepamicin은 최근에 소개된 gentamicin B의 유도체로 외국에서의 연구에 의하면 그람 음성 세균들에 대한 항균력이 우수함이 보고 된 바 있다. 본 연구에서는 우리나라의 임상 균주들을 대상으로 그람 음성세균에서 isepamicin의 시험관내 항균력을 기존의 아미노배당체 제재들과 비교하여 평가하고자 하였다. 재료 및 방법 : 2006년 1월에서 6월 사이에 서울아산병원 환자에서 분리된 Escherichia coli 113 균주, Klebsiella pneumoniae 110 균주, Pseudomonas aeruginosa 117 균주, Acinetobacter baumannii 108 균주, 그리고 Enterobacter cloacae 118 균주를 대상으로 isepaimcin, amikacin, gentamicin, tobramycin에 대한 최소억제농도(minimal inhibitory concentration, MIC)를 한천 희석법(Mueller-Hinton Agar)을 이용하여 측정하였다. 감수성여부는 CLSI 기준에 따랐으며, isepamicin은 MIC≤16㎍/mL를 감수성, MIC=32 ㎍/mL를 중등도 내성, MIC≥64 ㎍/mL를 내성으로 판정하였다. 결과 : Isepamicm의 E. coli, K. pneumoniae, P. aeruginosa, A baumannii, E. cloacae에 대한 MIC_(50)/MIC_(90)은 각각 1/2, 0.5/>128, 4/16, 16/>128, 1/2 ㎍/mL였고, 항균제 감수성률은 차례대로 100%, 86.4%, 89.7%, 50.0%, 96.6%였다. 기존 아미노배당체 제재들과 비교하면 E. coli, K. pneumoniae, P. aeruginosa, E. cloacae에서는 amikacin과 비슷한 감수성률을 보였고, gentamicin과 tobramycin보다 높은 감수성률을 보였다. A baumannii의 경우 isepamicin의 감수성률이 50.0%로 비교적 낮았지만 amikacin, gentamicin, tobramycin도 각각 50.0%, 46.3%, 47.2%의 감수성률을 나타내어 4가지 항균제가 모두 비슷한 항균력을 보였다. 결론 : Isepamicin은 그람 음성 세균들에 있어 기존의 아미노배당체 제재들과 비교했을 때 amikacin과는 동등한 시험관내 항균력을 보이고 gentamicin, tobramycin보다 뛰어난 시험관내 항균력을 보여 사용이 유망한 아미노배당체 중 하나라 생각된다.

權容俊,金光鎭 충남대학교 의과대학 지역사회의학연구소 1986 충남의대잡지 Vol.13 No.1

Sodium-potassium activated adenosine triphosphatase (Na-K-ATPase), which is contained in the cell membrane, have the important roles in the material transport through the cell membrane, especially sodium and potassium. And its activity is inhibited by a kind of cardiac glycoside, ouabain. Orostachys malacophyllus Fischer (Tsume renge) is a plant to grow on the tiled roof of the house, and in the field or mountain. And the compositions of the plant have not been known yet. But it has transmitted to this time as a kind of medical plant from remote antiquity. Sometimes, it is used in the folk remedies for the treatment of the malignant diseases. But it is not clear in the therapeutic effect. This study was attempted to investigate the effect of the water extract of Tsume renge on the Na-K-ATPase activity, which was purified from the outer medulla of pig kidneys. And the cell membrane fraction was incubated with sodium dodecyl sulfate and was purified by the method of Jørgensen. The results obtained were summarized as follows: 1. Na-K-ATPase activity of the control group was 3.6±0.3μM/g protein/10min. 2. Total ATPase activity was not affected by the concentrations between 0.01% and 1.0% of Tsume renge water extract solution. 3. 0.01% of Tsume renge water extract was increased the Na-K-ATPase activity significantly. 4. Na-K-ATPase activity was inhibited in the concentrations of 0.1%, 0.5%, and 1.0% of Tsume renge water extract. From the above results, it was suggested that the water extract of Tsume renge has dual effect in accordance with its concentrations.
