Diagnostic Significance of Total Lactate Dehydrogenase(LD) and LD Isoenzyme Measurement in the Body Fluids.: Chang Ho Jeon, Eun Kyung Bae, Seok Il Hong, Chung Sook Kim, Young Hyun Lee; Yeungnam Univ J Med. 1986;3(1):193-199.

Abstract PDF: Body fluid Lactate dehydrogenase and its isoenzyme Measurement was performed in 132 patients: 8 cases with peritonitis, 21 cases with malignant ascites, 43 cases with liver cirrhosis, 48 cases with tuberculous pleuritis, 12 cases with malignant pleural effusion respectively. Body fluid protein and glucose contents, red blood cell counts, white blood cell counts, cytologic examination were also performed as a comparative study. The results were as follows: 1. Measurement of total LD and protein amount could differentiate between transudate and exudates in the ascitic fluids. 2. In the malignant exudate of ascites and pleural fluid, the activity of LD2 isoenzyme was statistically increased compared with that of inflammatory exudates and the activity of LD4 isoenzyme was also incereased compared with that of serum (P<0.05). 3. The inflammatory exudates of pleural fluid and ascites demonstrated the increase of LD5 isoenzyme activity statistically compared with that of serum and malignant exudates (P<0.05). 4. A difference of total LD activity between malignant ascites and inflammatory ascites was significant statistically, while this was not observed in the pleural exudate. 5. Total LD and LD5 isoenzyme activity didn't correlated with the number of white blood cells in the exudate.

Statistical Analysis of Antimicrobial Susceptibility Tested on Various Clinical Isolates of Bacteria.: Eun Kyung Bae, Chang Ho Jeon, Seok Il Hong, Chung Sook Kim; Yeungnam Univ J Med. 1986;3(1):185-192. Published online December 31, 1986; DOI: https://doi.org/10.12701/yujm.1986.3.1.185

Abstract PDF: Antimicrobial susceptibility of the bacterial strains isolated from clinical specimens during the period from June, 1983 to June, 1986 in Yeungnam Medical Center was studied and the following results were obtained. 1. Staphylococcus aureus was highly susceptible to cephalothin and its susceptibility to methicillin was gradually reduced. 2. Streptococcus strains except enterococcus were generally susceptible to penicillin, while most enterococci were susceptible to only ampicillin. 3. Gram-negative rods including Escherichia coli were highly susceptible to amikacin and tobramycin. 4. Serratia were generally less susceptible to the amtimicrobials tested than other Enterobacteriaceae. Among them, Serratia marcescens showed the highest susceptibility to amikacin and chloramphenicol. 5. Pseudomonas aeruginosa revealed the highest susceptibility to amikacin and tobramycin and moderate susceptibility to carbenicillin and gentamycin. 6. Acinetobacter calcoaceticus revealed low susceptibility to most antimicrobials tested, showing only 30% susceptibility to amikacin, tobramycin and gentamycin in 1986.

A Numerical Coding System(MCRCODE-N) for Identification of Glucose Nonfermenting Gram-Negative Bacilli.: Seok il Hong, Chung Suk Kim; Yeungnam Univ J Med. 1985;2(1):183-190. Published online December 31, 1985; DOI: https://doi.org/10.12701/yujm.1985.2.1.183

Abstract PDF: The glucose nonfermenting gram-negative bacilli encountered about 10% of all gram-negative bacilli isolated from clinical material. Therefore, a rapid and correct identification of glucose nonfermenting gram-negative bacilli is impotent for a better management of infectious disease. There are many conventional systems for the identification of glucose nonfermenting gram-negative bacilli but most of them have problems and difficulties. Commercial Kit Systems exist and they are too expensive for daily use in Korea because of high cost. Based on 12 selected tests we propose a new code system, MCRCODE-N for rapid and inexpensive identification of glucose nonfermenting gram-negative bacilli. The selective 12 tests are oxidase, glucose oxidation motihty, urease, DNase arginine dehydrolase, nitrate reduction, gelatin Liquefaction, esculin hydrolysis, mannitol oxidation, maltose oxidation, Lactose oxidation. The 12 tests are divided 4 group and then each group has 3 tests. The result of each group is expressed by the number as below. The positive test is given by specific number (1st test=1, 2nd test=2, 3rd test=4), while any negative result is 0. Each 3 numbers of one group are added and make number of 1 digit. Four digit number is referred to the code book of MCRCODE-N system or MCRCODE system using computer (Apple-II model) created by authors. This MCRCODE-N system is suitable ones for out use in Korea. We propose the MCRCODE-N system for clinical use.
