The present study was designed to evaluate the efficiency of total lactate dehydrogenase, total creatine kinase, LD1/LD2 ratio, CK-MB and newly developed troponin T in acute myocardial infarction. The level of troponin T was 0.010.02 pg/L in 34 healthy person, but the peak vaule of acute myocardial infarction ranged in 4.7-24.2 pg/L. Total lactate dehydrogenase was peaked in 1 to 3 days after chest pain and then progressively decreased, but LD1/LD2 ratio was persistently higher than 1.0 for 10 days in most patients. Total creatine kinase and CK-MB were peaked in 1-2 days, and normalized in 3-4 days, so they, were useful in early diagnosis of acute myocardial infarction, but not for the late stages of acute myocardiz l infarction. Troponin T is early elevated and persistently high level for more than 10 days. Comparing with total lactate dehydrogenase, total creatine kinase, LD1/LD2 ratio and CK-MB, troponin-T test improves the efficiency of serodiagnostic method for the detection of ischemic myocardial damage.

OBJECTIVES: A different sequence change, in the mitochondrial tRNA gene, has been proposed as a candidate mutation in the sensorineurnal hearing loss. The purpose of current study is to identify the association between the noise-induced sensorineurnal hearing loss and the A to G mutation at nucleotide 3243 of mitochondrial DNA. METHODS: Subjects were established by history and chart review, and audiological and clinical data were obtained. Blood was sampled from 101 controls, 50 noise-induced hearing loss, and 12 sensorineural deafness. The DNA of these individuals was extracted, and mitochondrial genome was analyzed by polymerase chain reaction. Subsequently, the coding sequence of mitochondrial genome was sequenced, and compared to the normal sequence, and all sequence variations were analyzed by restriction endonuclease ApaI. RESULTS: Mitochondrial DNA mutation (3243A->G) was not detected by polymerase chain reaction (PCR) in any patients with noise-induced hearing loss, sensorineural hearing loss, and normal control without hearing loss in Koreans. The DNA sequencing of PCR products did not revealed an A to G substitution at nucleotide 3243 of mitochondrial DNA. CONCLUSIONS: The noise-induced sensorineural hearing loss was not associated with mitochondrial DNA mutation (3243A->G)

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.
