An increasing frequency of methicillin resistant S. aureus(MRSA), methicillin resistant coagulase negative staphylococci(MRCNS) and Enterococcal infection have been observed in recent years. Teicoplanin is a new glycopeptide antibiotic obstained from the Actinoplanes teicomycetius. The molecular structure and spectrum of antimicrobial activity of teicoplanin is simillar to those of vancomycin, and has been reported to have an excellent in vitro and in vivo effect against various gram-positive infections. Therefore, we evaluated the in vitor susceptibility of gram positive cocci, such as, S. aureus, coagulase negative Staphylococci(CNS), and Enterococci to teicoplanin and vancomycin. The total 253 strains consisted of MSSA(40), MRSA(53), MSCNS(47), MRCNS(48), and Enterococci(65). They were assayed by disc diffusion and agar dilution. During the study, 57% of S. aureus and 49% of CNS showed resistance to methicillin. The inhibitory diameter of teicoplanin was 15-20mm in MSSA, 12-19mm in MRSA, 13-24mm in MSCNS, 11-23mm in MRCNS, and 15-22mm in Enterococci respectively, and showed sensitivity in all but 8 strains(3.2%). The range of the minimum inhibitory concentration (MIC) of teicoplanin to MSSA, MRSA, MSCNS, MRCNS and Enterococci were 9.12-2.0㎍/ml, 0.25-2.0㎍/ml, & 0.25-32㎍/ml, 0.12-1.0㎍/ml respectively. One case of S. haemolyticus was resistant to teicoplanin (32㎍/ml) by the agar dilution method. Eight minor (3.2%) and one major(0.4%) error was observed when the MIC and disk diffusion data were correlated with teicoplanin. As for vancomycin the inhibitory diameter was 17-21mm in MSSA, 15-21mm in MRSA, 18-26mm in MSCNS, 18-25mm in MRCNS, and 16-22mm in Enterococci respectively. The range of the MIC of vancomycin to MSSA, MRSA, MSCNS, MRCNS, and Enterococci were 0.25-1.0㎍/ml, 0.25-4.0㎍/ml, 0.5-2.0㎍/ml and 0.5-2.0㎍/ml respectively. One minor error (0.4%) was seen with the vancomycin disk. The MIC90 of MSSA and MRSA exhibited the same results in teicoplanin (1.0㎍/ml, 1.0㎍/ml), and vancomycin(2.0㎍/ml, 2.0㎍/ml). MSCNS and MRCNS exhibited greater MIC90 with teicoplanin(4.0㎍/ml, 8.0㎍/ml) than vancomycin(2.0㎍/ml, 2.0㎍/ml). Incontrase Enterococci were more susceptible to teicoplanin(0.5㎍/ml) than to vancomucin (2.0㎍/ml). Results from this analysis indicated that both teicoplanin and vancomycin were very excellent for gram positive infections, especially those resistant to methicillin.

The purpose of the present research is to compare characteristics of maximal anaerobic power observed in different types of sports and player's sex differences. We have reached the following conclusions from the results we obtained by measuring maximal anaerobic power and blood lactate concentration of 60 elite university male and female players during the exercise of bicycle ergometer: 1. As to absolute and relative values of maximal anaerobic power, male players are higher in the order of rugby and handball, whereas female players are higher in the order of hockey and soccer, but no significant differences are observed between types of sports. 2. Male players are noticably higher in absolute values of maximal anaerobic power(p<0.001), but relative value is very simi1ar to that of female players. 3. It is estimated that the fact, that female players show obvious higher mean anaerobic power(p<0.001) during the 3,4KP excercise is due to sex differences in ocdurrence work load of maximal anaerobic power. 4. Comparison of blood lactate concentration at each work load in different types of sports and player's sex differences show an increase in proportion to mean anaerobic power. The results given above clearly show the differences between the type of sports such as rugby and hockey requiring power and speed, and the type of sports such as handball and soccer requiring edurance.

We used total of 12 middle school female students(3rd grade) as subject and devided them into two groups : The measurement items of cardiorespiratory functions were HR, VE, RQ, VO₂, VCO₂, VO₂/kg, O₂pulse, VE/VO₂, VE/VCO₂, before and after treadmill exercise load. The statistical analysis were M±SD and t-test for groups(α=.05) using ?? statistical package. The conclusion of this study was as follows ; 1. In 5 items(FM, LBM, %Fat, TBW, BMI) all of body composition, obese group has been significantly higher than normal group(P<0.01). 2. In heart rate and VO₂ of resting(before exercise loads) cardiorespiratory functions, normal group has been significantly higher than obese group(P<0.05). 3. In VEmax of cardiorespiratory functions after exercise loads, obese group has been significantly higher than normal group(P<0.05), and in VO₂max, obese group has been significantly higher than normal group(P<0.01). 4. In 1, 3, 5 minute percent recovery all of percent heart rate recovery after exercise loads, normal group has been higher than obese group but there was no statistical significant difference.

식품 및 생활폐수내의 존재하는 Salmonella spp.에 대한 효율적이고 신속한 동정을 위한 증진배야업을 개발하고자 하였다. 본 연구에 사용된 균주인 S. enteritidis 생육을 촉진시키기 위한 방법으로 cAMP 및 yeast extract를 사용하였는데 전자인 경우는 배지내의 농도가 10 mM 이상일 때 10^-3 cfu/ml의 균수로 7시간 배양후 균수가 control보다 약5배의 증가를 보였으며 후자인 경우는 0.6% 첨가시 10배의 증가를 보였다. 다른 균주들에 대한 선택적인 성장효과를 보기위하여 selenite broth와 bile salts를 사용하였고 이때 사용된 균주는 Staphylococcus aureus, Pesudomonas aeruginosa, Lactobacillus plantarum 및 Escherichia coli이었고 bile salts의 농도가 0.1%일때 네 가지 균주의 증식에 대한 억제 효과가 있었다. 두 단계의 증진배양법으로서 1차 증진배양에서는 selenite broth에 0.6% yeast extract를 첨가한 것으로 2차 증진배양에서는 0.1% bile salts를 첨가한 것으로 하였는데 타균과의 혼합배양에서 Salmonella의 초기균수가 10^0.3일 때 14시간 증진배양으로 10^8.5 cfu/ml까지 증식을 보였으며 초기균수가 1 cfu/100 ml인 경우는 10시간의 1차 증진배양과 6시간의 증진배양으로 약 10^7의 증식속도를 나타내었다. The development of an enrichment method for the rapid and effective identification of Salmonella spp. in sewage or food was studied. As a growth factor for Salmonella, 10 mM cyclic adenosine monophosphate (cAMP) in trypticase soy broth with 0.6% yeast extract (TSBYE) increased cell number five-folds and 0.6% yeast extract in selenite broth increased cell number ten-folds of control. Bile salts in slenite broth was tested for the selection of S. enteritidis in a mixture with Staphylococcus aureus, Pesudomonas aeruginosa, Lactobacillus plantarum and Escherichia coli. The latter four strains were effectively inhibited at 0.1% bile salt. A two-step culture method was used to enrich Salmonella spp.; a primary-enrichment and secondary-enrichment culture. At a primary-enrichment step, selenite broth with 0.6% yeast extract and 10 mM cAMP was used, and at a secondary-enrichment step, -0.1% bile salt was additionally used. Culture times of a primary-enrichment and a secondary-enrichment step were 8 hr and 6 hr, respectively. In this procedure, cell number increased from 10^0.3 to 10^8.5 with inhibition of other strains within 14 hr. In the case of an initial cell concentrarion as low as 10^-2 cfu/ml, a cell number increased to 10^7 cfu/ml by using a 10 hr primary-enrichment and 6 hr secondary-enrichment procedure.
