  • Six 3-dialkylaminomethyl-1-azaanthraquinones and five 4-dialkylaminomethyl-1-azaanthraquinones were synthesized and evaluated in vitro cytotoxicity against four human can cer cell lines. The compounds retained much of their cytotoxic activity against the multi-drug-resistant cell line (KB-V-1) as shown by resistance index.

  • The hexane fractions from methanolic extracts of Anetheum graveolens L. (Umbelliferae) and Acorus gramineus Soland. (Araceae) revealed potent inhibitory activities against the resistance of multi-drug resistant Staphylococcus aureus SA2 when combined with ampicillin (Am) or chloramphenicol (Cm). As active principles, carvone and the liquid mixture containing carvone from Anetheum graveolens L. and a liquid mixture mainly consisting of benzoic acid phenyl-methyl ester (benzyl benzoate) from Acorus gramineus Soland. were identified. They showed resistance inhibition at the level of 20-50${\mu}g$/ml when combined with 100 or ${\mu}g$/ml of Am or Cm, respectively.

  • Even for the same structure, the analysis results as well as design values might have differences depending on the selected analysis model. Therefore it is desirable to determin model considering the required accuracy of the analysis results, the given time restried economy.

In this study a 5 span steel box girl selected which satisfies the regularity and the applicability of the provided analysis simplified model in checked. For the comparision of the analysis results, "Multi-Mode Spect Method" is used with a detailed model.hod" is used with a detailed model.odel.

  • The essential oils from 73 aromatic herb drugs entered on Korean official formularies were tested for antibioticresistance inhibitory effect. When the oils were combined with ampicillin (Am) or amoxicillin (Amx) they showed significant inhibitory effects on the growth of multi-drug resistant Staphylococcus aureus SA2 in considerably low concentration. The most effective combination were oils from Magnoliae Flos or Piperis longi Fructus ($25{\mu}g/mL$)-Am or Amx ($4{\mu}g/mL$).

  • Leuconostoc spp. is intrinsically resistant against vancomycin and rarely causes the infection in immunocompromised patients. In this report, we describe a fatal case of Leuconostoc lactis bacteremia in a patient with biliary tract stent insertion to resolve the biliary tract obstruction by multiple pseudocysts in the pancreatic head region. Leuconostic lactis isolated from the blood of the patients was confirmed by 16S rRNA sequencing and this isolate was susceptible against most antibiotics, including levofloxacin, penicillin, erythromycin and cefotaxime except vancomycin. The septic shock and multi-organ failure was abruptly progressed due to delayed use of adequate antibiotic. Using vancomycin as the empirical antibiotics in a bacteremic patient by Gram positive cocci, the treatment failures by the isolates with intrinsic resistance against vancomycin have to be considered. In addition, the prompt and accurate identification of Leuconostoc spp. are very important to select the adequate antibiotics.

  • Extended spectrum β-lactamase (ESBL) generated Enterobacteriaceae including Escherichia coli is responsible for resisting antibiotics, which is clinical problem. This study was performed to investigate the isolation rates of 111 strains having positive of VITEK ESBL test 111 ESBL-strains in each month and season and statistically to determine their patterns of antibiotic test. One hundred eleven ESBL-strains were collected among 1,688 strains of E. coli isolated from various clinical specimen of one general hospital in Busan during 2002 to 2003. Month rates of ESBL-strains were 0% to 13.3%, while the seasonal rates were highest at autumns during two years. The resistance to ampicillin, cefazolin, azteronam, ceftriaxone, and cefepime were 100% in 2002. In ampicillin and cefazolin the resistances were 100% during the two years. There were significant differences of cefoxitin and piperacillin/tazobactam between the two years but not significant between specimens. Four groups were divided according to the pattern of resistance and then the highest group had 93∼100% of the resistance to 8 drugs but not resistant to imipenem.

  • The textbook of insurance medicine is very bulky volume and it's revision time may be long. Nowadays medical knowledge and evidences are developing rapidly. It is necessary to revise current insurance risk of certain disease. Review of respiratory diseases in terms of insurance medicine may be valuable information for insurance doctors and life underwriters. Newly estimated mortality ratio and excess death rate of several respiratory diseases in this review are organizing pneumonia, 266%/44‰; multi-drug resistant tuberculosis, 1200%/110‰; idiopathic interstitial pneumonia, 869%/85‰; VATS lobectomy of stage I lung cancer, 550%/33‰; lymphangioleiomyomatosis 9826%/66‰; lung transplantation 2026%/92‰, respectively.

  • Thirty six essential oils from herb drugs entered in Korean official formulary, which are frequently used in oriental region, were tested for antibiotic resistance inhibition. When the oils were combined with ampicillin (Am) or amoxicillin (Amx) they showed significant inhibitory effects on the growth of multi-drug resistant Staphylococcus aureus SA2 in considerably low concentration. The most effective combinations were oils from Acanthopanacis Cortex ($0.49{\mu}g/mL$) with Am and Cnidii Rhizoma and Lonicerae Flos (2.77 and $2.79{\mu}g/mL$, respectively) with Amx as shown in minimum resistance inhibitory concentrations.

  • We characterized the resistances such as to waterlogging, Phytophythora and viruses in hybrids between Italian and Korean mother lines and screened them for complex resistances and agronomic traits to select elite multi-resistant lines for hybrid breeding. Resistance to waterlogging was selectable due to diversity of the resistance. Phytophythora resistance introduced from Italian lines could also be combined with resistance to other diseases and restoration abilities from cytoplasmic male sterility that has been maintained in Korean varieties.

  • The complete nucleotide sequence of pKH6, a tetracycline-resistance (Tc$^{r}$) plasmid isolated from multi-drug resistant Staphylococcus aureus SA2, has been determined and compared with that of the staphylococcal Tc$^{r}$ plasmid pTl8l. The nucleotide sequences of the two plasmids are in agreement except for 7 nucleotides. All differences are caused by base pair substitutions. Among 6 substitutions, 3 occurred in coding regions. However, only two base substitutions in coding regions resulted in changes of amino acid sequences in two different ORFs of repC and Pre proteins.
