Background : In recent years, gonorrhea has been pandemic and remains one of the most common 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 Venereal Disease Clinic of Choong-Ku Public Health Center in Seoul since 1980 by means of the chromogenic cephalosporin method. Results : In 1997. 99 strains of N. gonorrhoeae were isolated, among which 45(45.5%) were PPNG. Conclusion : The prevalence of PPNG in Seoul, which had been decreased to 39% in 1996 after a peak of 74.3% in 1993, is increased to 45.5% in 1997.

, The relationship between physical activity and cognitive performance was studied in the elderly women. Fifty volunteers (60-74 yrs) agreed to participate and were placed in 2 groups; exercise group(n=25; 68.72±4.22 yrs) and Non-exercise group(n=25; 69.52±5.1 yrs). The subjects who joined in the exercise group were asked to participate in exercise program(3 times/week, 80 min/day) for 12 weeks. The subjects n both groups were tested on the cognitive psychomotor performance (finger simple reaction time(SRT) and choice reaction time(CRT), tapping, and eye-hand coordination) at the beginning and the end of the 12-weeks program. For data analysis, mean and standard deviation scores were calculated, and ANOVAs and MANOVAs were used. There was an interaction between Group(2 exercise and non-exercise groups) and Time (pre- and post-tests) on all cognitive psychomotor performance tasks. Especially, each group was significantly interacted with Times on the performance of eye-hand coordination. After the exercise program, the exercise group was significantly better than the inactive group on all dependent variables (SRT and CRT, number of tappings, and performance scores of eye-hand coordination).

자발성 신파열은 외상 혹은 수술 등의 병력 없이 신장 피막 혹은 신장 주위 혈종이 자발적으로 발생하는 드문 질환으로, 원인으로는 요로 결석[1], 결핵, 신우신염, 신농양 같은 감염성 질환이나[2] 신장의 종양 및 신장 이식 수술 후[3], 후천성 낭성 신환[4] 등이 관련이 있다. 그 중 복막 투석 환자에서 낭성 신질환에 의한 자발성 신파열은 국내 보고가 있었으나 요로감염에 의한 자발성 피막하 혈종을 동반한 신파열은 문헌 보고가 없었다. 저자들은 요로감염으로 진단된 환자에서 피막하 혈종을 동반한 신파열 1례를 경험하였기에 문헌 고찰과 함께 보고하는 바이다.
저혈청 배지에서 인간 전골수세포(HL-60)를 이용한 tPA 생산과 세포사멸기작에 관한 연구

tPA 생산과 세포 사멸의 연구를 하기 위해서 인간 전골수세포가 배양되었다. 연속 관류 배양하에서 최대 tPA 생산량은 324 ng/ml이며 최대 세포 농도는 5.27×10 exp (6) cells/ml였다. Phorbol ester를 넣었을 때 tPA 생산량은 420 ng/ml까지 향상되었다. 형광 현미경으로 관찰했을 때, apoptosis는 세포 배양 초기부터 중반까지 우세했고 빠른 교반 속도에서도 우세했다. 그러나 necrosis는 세포배양 말기와 동결된 세포가 해동 되었을 때 우세했다. HL-60 was cultivated to produce tPA (tissue-type plasminogen activator) and study the mechanism of cell death. Maximum cell density and tPA production were obtained as 5.27×10 exp (6) cells/ml and 324 ng/ml, respectively under perfusion cultivation. tPA production was enhanced to 420 ng/ml in adding 160 nM of phorbol ester. The cells were gradually differentiated to granulocytes rather than proliferation. By Fluorescent microscope, apoptosis was prevailed except the death phase and in high agitation speed, but necrosis was prevailed in thawed cells and during the latter periods of the cultivation. It was also proved that tPA was most produced in apoptosis. To obtain higher tPA productivity, the cells must be maintained in apoptosis, not necrosis phase when the cells were dying.

Fineness Modulus is a term used as an index to the fineness of sand. It is well - known that the modulus distribution of sand plays an important role in achieving the desired properties of mortar. The maximum size of sand is also important parameter in mortar. These parameters affect workability, strength and unitweight of mortar. In tills study, different sand gradings were used to investigate effects of fineness moduli of sand for examination about the workability, strength and unit weight characteristics of cement mortar. Two kinds of sands with various size distribution and three kinds of fine aggregates with the similar particle size distribution (Sieve No.16~30, No.30~50, No.50~100) were used. Water-cement ratio (W/C) of mortar mix was kept constant for all the trial mixes with sand of different fineness modulus. Major findings of tills study are: (a) Fine sand with the similar size distribution reduces the workability and unit weight of cement mortar. (b) The compressive strength of mortar is not sensitive to sand grading variations. (c) The compressive strengths at the age of 28 days range from 32.1 to 54.1 MPa. (d) The sand with standard modulus distribution has better positive effects on the properties of the mortar.
