This study was performed to examine the current management of hospital wastes and to investigate the contents. rules and systems concerning management of hospital wastes to find out the countermesures by the subjects. The amount and the present storage of hospital wastes and the collection. conveyance and handling of the consignment treatment company were investigated according to the examiration. the suitable treatment of hospital wastes has not been carrid out for the defect of the current management and handling capacity. To take charge of hospital wastes effectively and sanitarily. at the first place. a professional should understand the contents of wastes correctly and manage all systems by the characteristics. The improvement of storage and conveying container is required absolutly for sanitary management. An air-tight vessel should be used for storage container it should make a unification of a bicameral system.

Chrysanthemum boreale (C. boreale) has been used for the treatment of furuncles, carbuncles, sores, conjunctivitis, headache, vertigo and swollen throats as a folk medicine in Korea, but there is little report about experiment evidence of antimicrobial activity. To investigate the antifungal and antibacterial activity of Chrysanthemum boreale(C. boreale) volatile substance and EDTA, the growth inhibition against Aspergillus nidulans (A. nidulans), Fusarium oxysporum (F. oxysporum), Alternaria mali(Al. mali), Candida albicans (C. albicans), staphylococcus aureus (S. aureus), Streptococcus pyogenes(S. pyogenes), streptococcus mutans (S. mutans), Escherichia coli(E. coli), Helicobacter pylori (H. pylori) and Porphyromonas gingivalis (P. gingivalis) was monitored by agar dilution and broth microdilution method. The antifungal effect of C. boreale on A. nidulans, F. oxysporum, Al. mali and C. albicans was shown at the concentration of 0.04%. The antibaterial effect of C. boreale on S. aureus, S. pyogenes, S. mutans and H. pylori was shown at the concentration of 0.04%. However, the growth was inhibited at the concentration of 0.04% irrespective of the presence of EDTA 0.125% was much higher than higher than that of several concentration of volatile substance. The minimum inhibitory concentrations of volatile substance were 0.16% against S. aureus, 0.04% against S. pyogenes, 0.02% against S. mutans, 0.40% against E. coli, and 0.18% against C. albicans. The growth of human gingival fibroblasts was not affected by C. boreale volatile substances at the concentration of 0.04%. These results indicate that volatile substance from C. boreale may have biologically toxic activities to the microorganisms.

Background : In recent years, gonorrhea has been panedemic and remains one of the most commom STDs in the world, especially in developing countries. Objective & Methods: For the detection of a more effective therapeutic regimen and assessing the prevalence of PPNG, we have been trying to study the patients who have visited the VD Clinic of Choong-Ku Public Health Center in Seoul since 1980 by means of the chromogenic cephalosporin method. Results: In 1996, 139 strains of N. gonorrhoeae were isolated, among which 53(39.0%) were PPNG. Conclusion: Our results suggests that after a peak of 74.3% in 1993, the prevalence of PPNG in Seoul is gradually declining.

However, the growth of E. coli was not inhibited at the concentration of 0.04%. The minimum inhibitory concentrations of volatile substances were 0.16% against S. aureus, 0.04% against S. pyogenes, 0.05% against S. mutans, and 0.40% against E. coli. In the volatile substances of C, boreale, eighty-three compounds were identified by gas chromatographic analysis. The major constituents of the volatile substances were camphor, β-thujone, and 1,8-cineole+β-phellandrene. These results indicate that volatile substances of C. boreale may have antimicrobiol activities, and The major constituents of the volatile substances may be camphor, β-thujone, and 1,8-cineole+β-phellandrene.

Background/Aims: Percutaneous cholecystostomy (PC) is an effective treatment for cholecystitis in high-risk surgical patients. However, there is no definitive agreement on the need for additional cholecystectomy in these patients. Methods: All patients who were admitted to Cheju Halla General Hospital (Jeju, Korea) for acute cholecystitis and who underwent ultrasonography-guided PC between 2007 and 2012 were consecutively enrolled in this study. Among 82 total patients enrolled, 35 underwent laparoscopic cholecystectomy after recovery and 47 received the best supportive care (BSC) without additional surgery. Results: The technical and clinical success rates for PC were 100% and 97.5%, respectively. The overall mean survival was 12.8 months. In the BSC group, mean survival was 5.4 months, and in the cholecystectomy group, mean survival was 22.4 months (p<0.01). However, there was no significant difference between these groups in multivariate analysis (relative risk [RR]=1.92; 95% CI, 0.77-4.77; p=0.16). However, advanced age (RR=1.05; 95% CI, 1.02-1.08; p=0.001) and higher class in the American Society of Anesthesiologists` physical status (RR=3.06; 95% CI, 1.37-6.83, p=0.006) were significantly associated with survival in the multivariate analysis. Among the 47 patients in the BSC group, the cholecystostomy tube was removed in 31 patients per protocol. Recurrent cholecystitis was not observed in either group of patients during the follow-up period. Conclusions: In high-risk surgical patients, PC without additional cholecystectomy might be the best definitive management. Furthermore, the cholecystostomy drainage catheter can be safely removed in certain patients. (Korean J Gastroenterol 2014;63:32-38)
