Objective : We analyzed some physicochermical chracteristics of a constitutive β-lactamase from a clinical isolate of a Pseudomonas aeruginosa which resistant to various β-lactams except imipenem and susceptible to aminoglycosides the proportion of its contribution to such resistance profile. Method : 1. Antimicrobial susceptibility test was done by the broth dilution method. 2. In hibition profile was done using EDTA, HgCl₂ and p-chloromercuribenzoate (pCMB). We also measured 50% inhibitory concentration(IC??) using β-lactamase inhibitors, such as clavulanic acid, sulbactam. 3. Kinetics study for substrate profile was performed by spectrophotometric assay using crude extracts and various antimicrobial agents. Relative hydropysis rates were determined. 4. The isoelectric point(pI) was determined by isoelectric focusing. The molecular weight was estimated by SDS-polycrylamide gel electrophoresis. Results : 1. The strain was resistant to ceftriaxone, sulperazon, piperacillin, ceftazidime, and aztreonam, while it was susceptible to gontamicin, tobramycin, amikacin and imipenem. 2. The β-lactamase was not inhibited by EDTA, and pCMB, whereas it was inhibited by HgCI₂. The IC?? of clavulanic acid was over 100μM and that of sulbactam was 22μM. 3. The relative maximal hydrolysis rate was calculated by setting V_(max) for cephaloridine at 100. The enzyme hydrolyzed cephalosporins more rapidly than penicillins. 4. The pI was 9.3 by isoelectric focusing. The molecular weight was estimated to be 40kDa. Conclusion : According to its substrate profile, pI and molecular weight, the β-lactamase from a clinical isolate of P. aeruginosa was a cephalosporinase belonging to group 1 in the Bush-Jacoby-Medeiros classification scheme.

Background: We are in the edge of some human made disasters such as hazardous materials and air pollution, for example, the world news reported that the city of Bhopal, India had serious victims related with a leaking out of the chemical materials, Methyl Isocyanate and many people in India were killed by. These situations many people who live in this world are world are worrying about are not others, but just ours and people consider about that kind of the disasters are the possible situation to happen to all the people. Therefore, we performed this basic study to recognize the risk of Methyl Isocyanate leak accident and to prepare local disaster plan with EMS system. Method : Trace 8.0, a simulation software made by the U.S. company Safer System was used as a tool to estimate the diffusion distance, area and its victims at the concentrations of 0.02ppm, 0.2ppm 5ppm respectively for an assumed B-city of 2 hundred thousands population count in which was presumed 500kg Methyl Isocyanate gas to leak out. Results : 1. During 1 hour, maximum diffusion distances of 0.02ppm 0.2ppm and 5ppm were 5.41km, 1.61km and 0.29km respectively on the plume impact. 2. Maximum population counts influenced by Methyl Isocyanate gas at the concentrations of 0.02ppm 0.2ppm and 5ppm were 40838, 4346 and 222 on the plume impact, while those were 138238, 17261 and 1588 on the vulnerability impact, respectively. 3. Therefore, 17261 persons must put on respiratory device and 138283 persons must be evacuated to safety place within 1 hour. Conclusions : Only small amount leak of Methyl Isocyanate may cause tremendous chemical disaster in urban area so its disaster plan must be prepared with an accident simulation program and Material Safety Data Sheets(MSDS). Especially, nearby emergency center of an industrial complex must have a strong position about preparation of chemical disaster plan and perform a disaster dill of hazardous material accident annually.
