Tofisopam is a new type of tranquilizer valuable for the relief of anxiety and tension in a wide range of emotional disorders. Tofisopam has the therapeutic characteristics of a minor tranquilzer and a mild stimulatory effect. The purpose of the present study was to evaluate the bioequivalence of two tofisopam tablets, Grandaxin^TM (Hwan In Pharmaceutical Co., Ltd.) and Tofim^TM (Kyung Dong Pharmaceutical Co., Ltd.), according to the guidelines of Korea Food and Drug Administration (KFDA). Eighteen normal male volunteers, 23.11±2.83 years in age and 65.43±7.64㎏ in body weight, were divided into two groups and a randomized 2 x 2 cross-over study was employed. After one tablet containing 50㎎ of tofisopam was orally administered, blood was taken at predetermined time intervals and the concentrations of tofisopam in serum were determined using HPLC method with UV detector. The pharmacokinetic parameters such as AUC_t, C_max and T_max were calculated and ANOVA test was utilized for the statistical analysis of the parameters. The results showed that the differences in AUC_t, C_max and T_max between two tablets based on the Grandaxin^TM were -5.59%, 2.22% and -13.18%, respectively. Minimum detectable differences (Δ) at α=0.10 and 1-β=0.8 were less than 20% (e.g., 14.95% and 19.34% for AUC_t and C_max, respectively). The powers (1-β) at α=0.10, Δ=0.2 for AUC_t and C_max were 95.21% and 81.93%, respectively. The 90% confidence intervals were within ±20% (e.g., -15.64∼4.45 and -10.77∼-15.21 for AUC_t, and C_max, respectively). Two parameters met the criteria of KFDA for bioequivalence, indicating that Tofim^TM tablet is bioequivalent to Grandaxin^TM tablet.

Purpose : The aim of this study was to evaluate the bone mineral density of iliac and tibial bone which are frequently selected as autogenic bone graft donor sites, and to evaluate the efficiency of this method as a guideline for the selection of bone graft donor site. Materials and Methods : In this study 61 male and 70 female volunteers at Chungbuk National University Hospital were involved between Jan. 1998 to Sept. 1999. We measured bone mineral density of the iliac and the tibial bone using dual energy X-ray absorptiometry. We evaluated the data using the SAS system for Windows and bone mineral density of the lumbar was used for control. Results : Age showed the highest correlation in correlation matrix between physical and bone variables. Height and weight showed lower correlation of linear increment. In man, the change of bone density according to age demonstrated linear decrease irrespective of the lumbar, ilium, and tibia. In woman, the change of bone density according to age showed cubic form, which increased in the third and forth decade. So it had a peak bone mass on about 35 year-old, thereafter, the change of bone density slowly decreased until 50 year-old, but it rapidly decreased after 50 year-old and it slowly decreased again after 65 year-old. Both in all subjects and subject with osteoporosis, the change of bone mineral density according to age showed statistically significant decrease in lumbar and tibia, but ilium was irrespective. Conclusion : In patients of aged or with osteoporosis, ilium demonstrated less tendency of decrease in bone mineral density than tibla. So this preliminary study suggested that ilium seemed better donor site for autogenic bone graft than tibia.

The prestressed concrete girder bridges have been used widely at the domestic national road and highway because it is great in the functional and economical efficiency. It has also the advantage of convenience of design and construction due to using standard sections. However it could be easily verified that previous standard section of PSC girder is excessively designed, which has much more redundancy than is necessary against design loads. Therefore it would greatly influence on economic efficiency for domestic demands, if a section of PSC girder became more economical with satisfying all design criteria. Thus the optimum design for the section of PSC girder using an optimum design method has been performed to examine more effective and economic section than previous standard one.

본 연구는 복합레진의 표면 연마에 의한 표면 거칠기가 표면 색상과 투명도에 어떤 영향을 미치는가를 알아보고자 시행하였다. Charisma (Heraeus Kulzer GmbH, Domagen, Germany)의 B1과 A3, Esthet-X (DENTSPLY Caulk, Milford, USA)의 B1과 B3 레진으로 거칠기에 따른 표면 색상을 평가하기 위한 직경 8㎜, 두께 5㎜의 시편을 제작하고, Sof-Lex finishing & polishing system(3M, ESPE Dental Products. St. Paul USA)의 C, M, F, 및 SF 디스크로 시편의 한쪽 면을 연마하였으며, 연마 전 Mylar strip으로 압축된 면을 대조군으로 하였다. 거칠기에 따른 투명도의 차이를 평가하기 위한 두께 1 ㎜의 시편을 Charisma의 A3로 제작하여, 한쪽 면을 600, 1000, 1500 및 2000번 사포로 연마하였다. 각 시편의 연마 전과 후, 연마면의 CIE L^(*)a^(*)b^(*)값과 1 ㎜ 시편의 백색과 흑색 배경판 상에서의 Y값을 spectrophotometer인 Spectrolino (GretagMacbech, Regensdorf, Switzerland)를 사용해 측정 분석하였으며, 각 시편의 연마 전과 후의 평균 표면 조드 (Ra)값을 Surface Roughness Tester SJ-301 (Mytutoyo, Tokyo, Japan)로 측정했다. L^(*)값은 재료와 색상에 상관없이 가장 거친 Sof-lex C 디스크로 연마한 군에서 가장 높은 값을 보였으며 (p < 0.05). Esthet-X B3군을 제외한 모든 군에서 Ra값이 감소함에 따라 L^(*)값도 낮아졌다. a^(*)값은 표면 거칠기에 따라 특정한 변화 양상을 보이지 않았으며, b^(*)값은 Esthet-X B1군을 제외한 모든 군에서 Sof-lex SF 디스크로 연마 시 가장 높은 값을 보였으며 (p < 0.05), Charisma B1과 Esthet-X B3군에서 Ra값과 비교적 높은 상관 관계를 보였다. Contrast ratio는 1000번과 1500번 사포로 연마한 군간을 제외한 모든 군 간에 유의한 차이를 보여으며 (p < 0.05). 표면 거칠기가 감소함에 따라 contrast ratio도 감소하였다(R2 = 0.801). The objectives of this were to evaluate the effect of surface roughness on the surface color and translucency of the composite reins. Two composite resins (Esthet-X, Dentsply, Milford, USA and Charisma, Kulzer, Domagen, Germany) were used to investigate the surface color. Charisma was used to investigate the translucency. 40 disc samples (diameter: 8 ㎜, thickness: 5 ㎜) were made by each product to measure the surface color. Ploymerized each sample's one side was treated by Sof-Lex finishing and polishing system (Group C, M, F, SF). 40 disc samples (diameter: 6 ㎜, thickness: 1 ㎜) were prepared to measure the opacity. 1 ㎜ samples were ground one side with #600, #1000, #1500 and #2000 sandpapers. CIE L^(*)a^(*)b^(*) values of each 5 ㎜ thickness samples, and XYZ values of 1 ㎜ thickness samples on the white and black background were measured with spectrophotometer (Spectrolino, GretagMacbeth, Regensdorf, Switzerland). Mean surface roughness (Ra) of all samples before and after surface treatment was measured using the Surface Roughness Tester SJ-301 (Mytutoyo, Tokyo, Japan). Regardless of type and shade of the composite resin, L^(*) values measured in group C were higher than others (p < 0.05), and L^(*) value decreased as the Ra value decreased except B3 shade of Esthet-X. But there were no significant difference in a^(*) values among groups. In control group and SF, highest b^(*) values were measured (p < 0.05), except B1 shade of Esthet-X. Contrast ratio decreased as the Ra value decreased (p < 0.05). With the above results, difference of surface roughness has influence on surface color and translucency of dental composite resins. 〔J Kor Acad Cons Dent 31(4):312-322, 2006〕

기저세포암 및 편평세포암에서 미세혈관밀도와 p53 단백 발현에 관한 연구

Basal cell carcinoma(BCC) and squamous cell carcinoma (SCC) are very prevalent neoplasms of the human skin. Ultraviolet radiation in sunlight is a well-established mutagen of the p53 gene and is one of basal cell carcinoma and squamous cell carcinoma. The newly-formed vascular network is important for neoplasms to grow beyond a size of about 1 ㎣. Recent reports have suggested the hypothesis that a mutant p53 protein is closely related with capillary density. Immumohistochemistry for p53 protein and CD34 was performed in 20 cases of BCCs and 14 SCCs to evaluated the relationship between p53 protein and capillary density. The results were as follows:1. The microvessels stained by CD34 were mainly located in the interface of tumor cells and stroma. 2. There was no difference in the microvessel density according to the histologic types and age of the patients, but a higher microvessel density was noted in male patients. 3. The aggressive BCCs and the less-differentiated SCCs showed higher p53 immunostaining. 4. The mean microvessel density of cases showing strong positive immunostaining of the p53 gene(54.73±17.75) was higher than that of others(39.75±18.30). These results suggested that p53 protein expression and microvessel density are not related to the histologic types and age of the patients, but that differentiation and biologic behavior such as the infiltrating property of tumors and the microvessel density are closely related to p53 protein expression.
