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.

Diamond particles in the Ni sulfamate electrolyte solution were deposited with nickel onto steel wire and codeposition mechanism of diamond and nickel was studied also under rotating disc electrode geometry. Composite coating is the method that codeposit inert particles in the electrolyte with metal matrix to improve material properties such as wear resistance, corrosion resistance and hardness. Effect of potential, initial diamond concentration and rotating speed on Ni-diamond composite coatings were studied. Increasing of initial diamond concentration and rotating speed enhance the codeposition ratio of diamond and mass transfer of nickel ions. As diamond in the deposits increase, hardness of deposits increase, and friction coefficient is lowered. Zeta potential of deposits increase, and friction coefficient is lowered.

Recently, high productivity and cost reduction becomes the most important target of industries due to the worldwide economic competition. One of these efforts is High Speed Machining(HSM), which reduces machining time with the increase of machining speed such as cutting speed and feedrate. It is very important, especially in case that the portion of machining time in production cost it high. This research suggests optimum cutting conditions to reduce cutting time with minimizing form error. For this study, a comprehensive model representing the texture of machining surface is developed, including rubbing phenomenon on the tip of ball end mill and expanded rubbing zone trajectory caused by tool deflection. Experiments show that the suggested set of feed and pick feed is optimum for maintaining the surface roughness identified by rubbing and low cutting speed in minimum

관상동맥조영술중 비이온성 조영제 Iodixanol (Visipaque®)에 의해 발생한 아나필락시양 반응 1예

최원욱,조정수,김성철,김상훈,안영수,최재웅 대한내과학회 2004 대한내과학회지 Vol.66 No.1

흉통을 주소로 내원한 45세 남자에서 관상동맥조영술 중 비이온성 조영제에 의하여 아나필락시양 반응이 발생한 증례를 경험하였기에 보고하는 바이다. Radiocontrast agent infusion is the most common cause of non-IgE mediated anaphylactoid reaction in the modern medical procedures. The newer lower-osmolar nonionic contrast agents cause significantly lower adverse reactions than the high-osmolar ones. However, anaphylactoid reaction to nonionic contrast agent can cause life-threatening events and even death has been rarely reported. Iodixanol (Visipaque®) is a nonionic, dimeric contrast agent, which is currently used in cardiac catheterization. Here we report a case of anaphylactoid reaction to Iodixanol, a nonionic radiocontrast agent, during cardiac catheterization. A 45-year-old male patient underwent cardiac catheterization for evaluation of substernal pain during exercise. Five minutes after this contrast injection to the left coronary artery, he complained itching and dizziness. Subsequently, generalized urticaria, cyanosis and hypotension were developed. His coronary angiogram showed normal findings. He was treated with intravenous fluids, intravenous diphenhydramine, sucutaneous epinephrine and sympathomimetics and one hour later he recovered. This case suggests that anaphylactoid reaction to a radiocontrast media, iodixanol, should be considered in the list of differential diagnoses for cardiopulmonary arrest during cardiac catheterization.
