Major pathogenic Gramnegative organisms such as P. aeruginosa, Serratia species, E. coli, Enterobacter species which are isolated from the specimens in large medical centers are greatly resistant to the commonly used antibiotics. Gramnegative bacilli, which had been isolated in Yeungnam Uni rersity Hospital during the period from December 1992 to April 1993 and turned out to be resistant to the primary antibiotics susceptibility test for chloramphenicoi, ampicillin, eephaiothin,- geniamicitt, tetracyclin, amikin and tobramycin, were subjected to the secondary antibiotics susceptibility test for aztreonam, ceftazidime, ciprofloxacine, cefotaxime, cefamandole, piperacillin, ticarcillin and sulfamethoxazole trimethopime. Out of 315 tested organisms, 167 organisms (53%) were resistant to all secondary antibiotics in vitro. Antimicrobial activity of ceftazidime (37.1%), aztreonam (11. %), ciprofloxacine (7.9%) against Gram negative bacilli were slightly more active than other antibiotics tested, while cefamandole was not active to all the Gramnegative bacilli tested. According to the specimens, E. coli was the most frequently resistant organisms to the primary antibiotics from urine, A. baumanii, from respiratory system and wounds, and P. aeruginosa from various specimens. In summary, Gram negative bacilli resistant to the primarily applied antibiotics also were resistant to the secondary antibiotics. Rearrangement of the antibiotics disks for the antibiotic susceptibility test should be considered.

Conjugative R plasmids derived from 74 clinical isolates of Serratia marcescens were epidemiologically analyzed for antimicrobial resistance, EcoRI restriction endonuclease analysis and Southern hybridization with DHFR, TEM and SHV probe. 1. Resistance frequency of isolates against various B-lactam antibiotics was changed by year. 2. Twenty (27%) resistant strains transferred 32 R plasmids to E. coli or Klebsiella by mixed culture. Most strains isolated from 1994 to 1996 transferred only trimethoprim resistance but most strains isolated from 1997 did resistances against gentamicin (Gm) and B-lactams including ampicillin (Ap), carbenicillin (Cb), cefazolin (Cz), cefaloridine (Cl), cefamandole (Cn). 3. Ten plasmids of GmApCbCzC1Cn or GmApCbCzC1 pattern and 3 plasmids of TcSuGmTbApCbCzC1 pattern respectively showed identical EcoRI restriction endonuclease digestion patterns and hybridized fragment patterns with TEM-1 probe by Southern hybridization. These results indicate that the epidemic plasmids carrying blamM gene were present in this hospital in 1997 and molecular genetic analysis of R plasmids can be used to discriminate S. marcescens isolates for epidemiologic studies.

Several of the newer broad-spectrum, potent antibiotics are currently being used for the treatment of meningitis, ventriculitis and shunt-tract infection. The risk of complications following intrathecal administration of some of this newer antibiotics varies considerably. Possible complications of immediate or delayed seizure, cortical electric depression, radiculopathy, transverse myelopathy, and arachnoiditis after intrathecal or intraventricular administration must be weighed against the potential value of this route. These risks may influence the therapeutic management of a specific clinical situation. The author studied the effect of the first generation of cephalosporins(cepalothin, cefazolin, cepharadine, cephapirin), the second generation of cephalosporins(cefamandole, cefmetazole), and the third generation of cephalosporins(cefotaxime, cetriaxone, cefotetan), on electrocortical activity of cerebral cortex. The results are as follows : 1) The topical application of cephalothin, cefazolin, cephapirin 8mg/ml shows electrocortical spike activity. In higher concentration, each cases show intense electrocortical spike activity. The topical application of cephradine 100mg/ml shows electrocortical spike activity and in higher concentration, electrocortical spike activity continued. 2) The topical application of cefamandole 64mg/ml shows electrocortical spike activity first and that of cefmetazole 100mg/ml shows electrocortical spike activity and in higher concentration of each cases, intense electrocortical spike activity continued. 3) The topical application of cefotaxime 16mg/ml shows electrocortical spike activity and that of ceftriaxon 200mg/ml and cefatetan 100mg/ml shows mild electrocortical spike activity. In higher concentration of each cases, electrocortical spike activity continued. In conclusion, the degrees of epileptogenic effect was most severe in the first generation of cephalosporins and the second generation of cephalosporins and the third generation of cephalosporins on the decreasing order.

We recently noticed four cases of Vibrio(V.) vulnificus infection from July, 1985 to September, 1985. The V. vulnificus was isolated by culture from the necrotizirig skin bullae in three cases, blood culture in two cases, and cerebrospinal fluid(CSF) in one case. The clinical characteristics of V. vulnificus infection in our cases was as follows: 1)All patients were men with their age over forties and the outbreak of the disease was during the summer season. 2) It was suspected that all patients had the previous hepatic problems. 3) The skin lesions showing bullae in three patients and subcutaneous nodules in one patient were noticed. 4) Two patients were showed positive in blood culture and one of thern also showed positive in lesional skin, urine and CSF. Lesional skin culture showed positive in three patients. 5) The isolated v. ulnificus was sensitive to chloramphenicol, erythromycin, gentamycin, kanamycin and cefobid. 6) Two patients died due to sepsis within 48 hours after liospitalization and one patient died due to hepatic failure.

Anaphylaxis caused by beta-lactam antibiotics usually develops following the systemic administration of the drug, although it can also occur with trivial contact of the drug on the skin in extraordinarily sensitive individuals. Cefotiam is a second-generation cephalosporin developed in Japan, and cefotiam-induced contact urticaria and systemic symptoms (contact urticaria syndrome) have been reported in several nurses from Japan and Korea. Considering the serious nature of the systemic manifestations, such as hypotension, contact anaphylaxis is a more appropriate name for severe forms of the disease than contact urticaria syndrome. No previous study has reported a case involving contact urticaria syndrome to multiple drugs. We describe a case of cefotiam-induced contact anaphylactic shock combined with cefoperazone/sulbactam-induced contact urticaria syndrome in a 24-year-old nurse. She exhibited positive skin prick test responses to both cefotiam and cefoperazone/sulbactam.

Polymicrobial nature of diabetic foot infection has been well documented in the literature. Initial antibiotic therapy of diabetic foot infection is usually empiric until reliable culture data is shown. This study was carried out to determine the common bacteriological flora of diabetic foot infection and antimicrobial sensitivity pattern in order to enhance possible empiric treatment. The specimens were obtained from wounds of 207 cases of diabetic foot ulcer, and the bacteriological isolation, and antimicrobial susceptibility tests of the isolates were carried out by standard microbiological methods. Staphylococcus aureus was the most common isolate, with 46.2% of recover rate among total bacterial isolated cases. Among gram-negative organisms, Pseudomonas aeruginosa was most common. Gram-positive organisms showed significant susceptibility to clindamycin, trimethoprim/sulfamethoxazole, and levofloxacin, besides vancomycin. Cefoperazone, piperacillin/tazobactam, and amikacin in addition to imipenem were most effective agents compared to gram-negative organisms. Diabetic foot infection requires use of combined antimicrobial therapy for initial management. Our results indicate that the most effective antibiotic combination for diabetic foot infection of Korean patients is clindamycin plus cefoperazone.

Because of increasing resistance of circulating N. gonorrhoeae and frequent failures in the treatment of gonorrhoea, intensive work on gonorrhoea has become of paramount importance. During January 1980-April 1984, at the Choong-Ku VD Clinic in Seoul, 3,340 male patients with uncomplicated gonococcal urethritis were treated with various treatment regimens. Diagnosis of gonorrhoea and declaration of a treatment failure were made on the basis of positive urethral culture. In 1984, the prevalence of Penicillinase Producing N. gonorrhoeae (PPNG) was about 30%, The pretreatment minimun inhibitory concentration of various antibiotics were quite high. Even for non-PPNG urethritis standard penicillin regimens gave unsatisfactory results. For PPNG urethritis, only spectinomycin, cefoperazone and cefotaxim-probenecid regimens gave satisfactory results. No spectmomycin resistant strain of N. gonorrhoeae has been found since 1982 at the Choong-Ku VD Clinic. As an agent of single drug therapy, spectinomycin seems to be one of the most cost effective drugs in the treatment of uncomplicated gonorrhoea in men.

Simultaneous drug-induced immune hemolytic anemia (DIIHA) caused by multiple drugs is rare. We report a case of a patient who developed DIIHA caused by 2 drugs. The patient's serum exhibited agglutination of ceftizoxime- or sulbactam-coated red blood cells (RBCs; via a drug-adsorption mechanism) and of uncoated RBCs in the presence of sulbactam (via an immune-complex mechanism). Although ceftizoxime is known to exhibit a positive reaction by an immune-complex method with or without reactivity with drug-coated RBCs, this patient's antibodies were reactive only against drug-coated RBCs. On the other hand, sulbactam, which is known to cause hemolytic anemia by nonimmunologic protein adsorption, exhibited positive reactions in tests with both drug-coated RBCs and in the presence of sulbactam. This is the first report of DIIHA due to a sulbactam-cefoperazone combination and the fourth report of DIIHA due to ceftizoxime. Owing to the patient's complicated laboratory results, DIIHA was suspected only at a late stage. We propose that for the prompt diagnosis of DIIHA, tests for all possible causative drugs should be conducted by 2 methods.

It is well known that renal cell carcinoma shows poor responses upon chemotherapy, and a multidrug-resistance has been suggested as one of the possible mechanisms of these resistances to chemotherapeutics of renal cell carcinoma as well as other malignancies. We tried to measure the expressions of the multidrug resistance gene and p-glycoprotein in human renal cell carcinoma cell lines, and to evaluate whether various multidrug resistance modulators could enhance the cytotoxicity of adriamycin. Four human renal cell carcinoma cell lines, A-498, A-704, Caki-1, Caki -2, were used and verapamil, cyclosporin A, cefoperazone, quinidine were used as the multidrug resistance modulating agents. Polymerase chain reaction was used to detect the expression of MDR1 mRNA, and measurement of p-glycoprotein was done by FACScan using JSB-1 monoclonal antibody. Cytotoxicity of adriamycin was measured by MTT colorimetric assay. Expression of MDR1 mRNA was observed in A-704, and A-498, but was not detected in Caki-1 and Caki-2. Expression of p-glycoprotein was found in A-498 and A-704, but not in Caki-1 and Caki-2. The relative expression rates of MDR1 and p-glycoprotein in A-498, A-704, Caki-1 and Caki-2 comparing to KB-3-1, the negative control cell line were 1.75, 2.44, 0.98, 0.97 and 1.31, 1.12, 1.08, 0.78 respectively. From these observations, A-498 was selected as MDR positive cell line and Caki-2 as MDR negative cell line, and then a study was performed to evaluate the effect of multidrug resistance modulators on the cytotoxicity of adriamycin upon these cell lines. Verapamil, in concentration of 0.1/microM, did not enhance the anticancer effect of adriamycin on A -498 cells, but with the concentration of 1 microM and 10microM, it decreased IC(50) of adriamycin from 0.43 microgram/ml when only adriamycin was used to 0.21 and 0.16, showing the dose modification effect of 2. 05 and 2.68 respectively (p<0.05, by Mann Whitney test). Cyclosporin A, in all the concentration of 0.3, 1, 3 microM, also decreased IC(50) of adriamycin on A-498 cells to 0.17, 0.14, 0.15 microgram/ml respectively, showing the dose modification effect of 2.53 to 3.07 (p<0.05, by Mann Whitney test). But the cytotoxicity of adriamycin was not influenced by cefoperazone and quinidine. In Caki-2 cells, in which MDR1 and p-glycoprotein expression were barely detected, verapamil and cyclosporin A as well as cefoperazone and quinidine did not show any effect upon the cytotoxicity of adriamycin. Considering above results, verapamil and cyclosporin A seem to be an effective multidrug resistance modulating agents to enhance the cytotoxicity of adriamycin in renal cell carcinoma showing MDR1 and p-glycoprotein expression, and further studies including in vivo study are needed before clinical trials to improve chemotherapeutic effect upon renal cell carcinoma.

This multi-center study was performed prospectively to evaluate the causative organisms and antibiotic sensitivity of isolates in bacterial keratitis from April 1995 to December 1998. Total number of infectious keratitis was 1002 cases. Among them,279 cases were confirmed with bacterial keratitis and 314 strains were identified. Major causative organisms of bacterial keratitis were Pseudomonas aeruginosa 121 strains (38.54%), coagulase negative staphylococcus (CNS) 34 strains (10.83%), Streptococcus pneumoniae 19 strains (6.81%), Staphylococcus aureus 18 strains (5.73%), and Serratia marscence 16 strains (5.10%). P.aeruginosa was highly sensitive to ciprofloxacin, ceftazidime, piperacillin, cefoperazone, imipenem,tobramicin,and gentamycin. Coagulase negative streptococcus showed high sensitivity to vancomycin, teicoplanin, clindamycin, and ciplofloxacin, but low sensitivity to penicillin and gentamycin. In conclusion, the choice of the effective antibiotics in the treatment of bacterial keratitis were essential to decrease resistant bacterial strains.
