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.
항생제 다제내성균 Staphylococcus aureus SA2로부터 분리한 테트라사이클린 내성 플라스미드 pKH6의 염기서열
이대운,윤성준,김우구,신철교,임성환,이백락,문경호 한국미생물생명공학회 ( 구 한국산업미생물학회 ) 1996 한국미생물·생명공학회지 Vol.24 No.4
한국에서 임산균주로부터 분리한 테트라사이클린(Tc) 내성 플라스미드 pKH6의 전체 염기서열을 결정하여 가장 대표적인 Tc 내성 플라스미드인 pT181과 비교하였다. pKH6의 전체 길이는 4439bp로 pT181과 동일하게 나타났으며 염기서열은 7개의 염기에서 차이를 보였다. 전부 다 염기쌍이 치환된 형태로 나타났으며 그 중 3개는 coding 부위에서 일어났다. coding 부위에서 일어난 경우에도 1개는 동일한 아미노산을 coding 하였기 때문에 pT181과 차이가 없었으며 RepC와 Pre 단백질에 있어 각각 1개의 아미노산에서 차이를 나타내었다. The complete nucleotide sequence of pKH6, a tetracycline-resistance (Tc^r) plasmid isolated from multi-drug resistant Staphlococcus aureus SA2, has been determined and compared with that of the staphylococcal Tc^r plasmid pT181. The nucleotide sequences of the two plasmids are in agreement except for 7 nucleotides. All differences are caused by base pair substitutions. Among 6 substitutions, 3 occurred in coding regions. However, only tow base substitutions in coding regions resulted in changes of amino acid sequences in two different ORFs of repC and Pre proteins.

This study emphasize on removal of organic matter by indirect oxidation process. In the electrolytic treatment, ??, ?? is producted by chloride. ??, ?? is used to organic matter oxidation. This study was conducted for the effects of organic matter oxidation, electrolysis time, electric current, ?? concentrations, and pH due to production of ??, ?? by electrolysis. Also, possibility on the second treatment by activated carbon adsorption was investigated. The results obtained were as follows : pH was rapidly increased less than 10 minutes, and was maintained after 30 minutes. When the temperature was not constantly maintained. The removal rate of TOC was increased up to 32% with the increasing of ?? concentrations and the increasing of electrolytic current. Effects of pH was not observed. When electrolysis was not carried out, adsorption constant k and 1/n were 0.017, 1.684, respectively. After the electrolysis with 1, 3, 5, 8A electrolysis, k and 1/n were 0.02, 0.022, 0.025, 0.018, 0.874, 0.518, and 0.887, 0.77, respectively. This result indicated that the wastewater included some material which is difficult to decompose. This wastewater need to pretreatment rather than independent electrolysis.

This shudy is that the jumping decathlon for the effect of training had introduced by Derek Boosey was applied to relatively excellent athletes for improving the specific physical fitness of jumpers, and their record was measured, in case their materials will be compared, analyzed definitely, as follows ; 1) Jumper(Long Jumper, Triple, High Jumper, Pole Vault)in the excellent group in all the terms, especially. They are above-average in 2 hop step & jump, 2 hop 2 step & jump, 2 hop 2 step & 2 jump and so on, but they are below-average at run 4 hop & jump. Therefore, in all the items, there is p〈0.001 difference between two groups. 2) jumper, in the average athletes group, excel slightly in the 2 hop step & jump, 2 hop 2 step & jump, 2 hop 2 step & 2 jump. But they don't excel at most of all items there is p〈0.001 difference between two groups. In conclusion, our country (Korea) jumping athletes are inferior to those of the average world in the specific physical fitness. And the specific physical fitness is closely related to each item each other, because of the similarity of the specific physical fitness element. This element is very important requisite to improve the record of the jumping. In consideration of this result, if we make use of this fundamental mat on training, this materials will be helpful to improve the specific physical fitness of jumpers.

This experiment was carried out to investigate the effects of superovulation on the ovarian response and embryo production of young and matured heifers. The possibility of mon-surgical recovery from the young heifers and transfer of recovered embryos to the mature recipients was also investigated. A total of 8 heifers(5 heads of Holstein, 2 Heads of Korean Native Cattle(KNC)and one head of Angus×Hereford crossbreed)were devided into 2 groups by their age. Young heifers(Group I)were 7∼10 months old and mature heifers(Group II)were 12∼18 months old. Group I and II were superovulated with muscular injection of 1,000 or 2,000 IU Pregnant Mare's Serum Gonadotrophin(PMSG)on day 10∼12 of estrus cycle followed by muscular injecion of 25mg Prostaglandin F ₂α(PGF₂α) 48 hours later. Heifers were artificially inseminated or copulated 2∼3 times with the interval of 12 hours while they were in heat. The embryos were collected non-surgically on day 6 of estrus cycle. The results obtained from this study were summarized as follows: 1. The average number of corpus lutea(CL) by the superovulation treatment was much greater in Group 11(9.2)than in Group 1(3.2) 2. The average number of unruptured follicles by the superovulation treatment was much greater in Group II(6.8)than Group I(1.0) 3. The interval to onset of estrus after PGF₂αinjection was longer in Group I(44.2 hours)than in Group II(31.8 hours).

Thermoplastic composites have great advantages over thermoset composites in productivity and properties. However, thermoplastic composites have not been used so widely because of difficulty in impregnation of their materials. In this study, the unidirectional composites were fabricated under different holding times by using commingled yarn(CY) and uncommingled yarn(UY). we investigated 0° and 90° bending strength and DSC analysis of thermoplastic composites which consisted Polypropylene(pp), Nylon6(Ny6) and Polyethylene telephtalate(PET) as the matrixs fiber and glass fiber as the reinforecement respectively.

A 17-year-women developed mixed warm and cold antibody type autoimmune hemolytic anemia associated with systemic lupus erythematosus. The patients was admitted to our hospital for syncope. Jaundice was observed. Urinalysis revealed protein and hemoglobin. Her hemoglobin was 4.6g/dl and reticulocytes were 10%. Total bilirubin was elevated, while haptoglobin and complement were abnormally reduced. ANA and mitochondrial Ab were detected. The direct and indirect Coombs test were positive. The direct antiglobulin test was positive ; IgG and C3d were detected on the red cell surface. The cold agglutinin(CA) titer was 128. The patients was initially treated with high dose steroid therapy. However the patients did not responded to high dose steroid therapy. We treated the patients with plasmapheresis and synchronized cyclophosphamide therapy. Clinical remission of hematologic complications was achieved in this patients. We report a case of mixed type autoimmune hemolytic anemia with SLE that responded plasma pheresis and synchronized cyclophosphamide therapy.
