The purpose of the study was to undertaken to analysis the Grab starting technique between national representive team(3) and Cheju's representive team(3) with 3D cinematography. The conclusions obtained were as follows: Cheju's showed more elapsed time than national representive team on starting block. and more vertical than horizontal direction of COG position, more concentrated vertical velocity & acceleration than forward direction. Therefore It is necessory for cheju's to train balanced trust force in horizontal and vertical direction in grab starting technique.

To develop and aceclofenac soft capsule, four preparations with various solubilizers were prepared and their dissolution test was carried out. Among four preparations tested, a preparation with ethanolamine was selected a formula of aceclofenac soft capsule (Clanza S^(™), since it showed the fastest dissolution rate. Bioequivalence of aceclofenac tablet, Airtal^(™)(Dae-Woong Pharmaceutical Co., Ltd.) and aceclofenac soft capsule, Clanza S^(™)(Korea United Pharmaceutical Co., Ltd.) was evaluated according to the guideline of KFDA. Fourteen normal male volunteers (age 20-25 years old) were divided into two groups and a randomized 2×2 cross-over study was employed. After oral administration of one tablet or capsule containing 100 ㎎ of aceclofenac, blood ws taken at predetermined time intervals and the concentration of aceclofenac in plasma wa determined with an HPLC method under UV detector. The pharmacokinetic parameters (C_(max), T_(max) and AUC_(t)) were calculated and ANOVA was utilized for the statistical analysis of parameters using logarithmically transformed AUC_(t), C_(max) and T_(max) between Airtal tablet and Clanza soft capsule were 2.89%, 0.18% and 43.0%, respectively. There were no sequence effects between two formulations in these parameters. The 90% confidence intervals using logarithmically transformed data were within the acceptance range of log(0.8) to log(1.250(e.g.log(0.81) - log(1.23) and log(0.89) - log(1.14)) for AUC_(t) and C_(max), respectively. Thus, the criteria of the KDFA guidelines for the equivalence was satisfied, indicating that Clanza S^(™) soft capsule is bioequivalent to Airtal^(™) tablet.

As medical technology progresses rapidly, there is a rise in the average age along with the Korean dietary lifestyle becoming more westernized, which leads to an increase in the number of vascular disease patients in Korea. Thus, we need to manage the medical information of a disease systematically in order to diagnose and treat constructively. However, since there has been no standardized method of man agement to date, a great deal of information could not be properly utilized nor studied. Therefore, the departments of Cardiology, Radiology and Neurology of Samsung Seoul Hospital recently got together to develop an information management system called the Vascular Data System. This program was developed to be run on win98 O/S, upper Pentium Ⅲ, and upper 128 MB Memory, and its source code is Dephi 4.0. It was configured for the user to set the configurations as well as do a variety of search and analysis. If this program were to be updated continuously, it may be used extensively as well as in various parts of clinical research activities.

<P><B>Abstract</B></P><P>Unregulated activation of microglia is a key risk factor contributes to neurodegenerative diseases and suppression of this phenomenon is considered as a potential therapeutic target. The compound isolated from sea horse <I>Hippocampus kuda</I> Bleeler; 1-(5-bromo-2-hydroxy-4-methoxyphenyl)ethanone [SE1] was characterized for its ability in suppressing LPS mediated activation of murine BV-2 cells. Despite the presence of various active molecular groups in the structure, SE1 has not well explored for its biological activities. The outcome of this study clearly indicated that SE1 inhibited the production of inflammatory mediators; nitric oxide, prostaglandin E<SUB>2</SUB> and pro-inflammatory cytokines. Furthermore, it inhibited the protein and gene expression levels of inducible nitric oxide synthase, cyclooxygenase-2, tumor necrosis factor-α, interleukin-1β and interleukin-6. The responsible signaling mechanisms leading to these inhibitions were identified as SE1 mediated blocking of phosphorylation of mitogen activate protein kinase (MAPK) molecules; C-jun-N-terminal kinase (JNK), p38 and nuclear translocation of nuclear factor-κB (NF-κB) p65 and p50 subunits. These results suggest that SE1 has the potential to be further developed as therapeutic against neuro-inflammation.</P> <P><B>Graphical abstract</B></P><P><ce:figure id='f0045'></ce:figure></P>

Four Years Reports of "Journal of Korean Neuropsychiatric Association" during 2001 to 2005 were evaluated by 18 Editorial Board of Korean Neuropsychiatric Association. We investigated the articles to specific fields and rejection rate etc. by different section chiefs. Although several problems concerning review time duration and rejection guideline issues indicated but generally all reviewer processes proved relatively clear and concise criteria. Through these objective and systematic evaluation Processes, "Journal of Korean Neuropsychiatric Association" will develop a good journal.

The working time of dental cement has a close relation with the setting time, where the setting reaction can be said as the result of the chemical reaction between cement liquid and powder. The purpose of this experiment was to investigate the setting characteristics and setting rate of dental cements by measuring the exothermic heat(Joule/gram) from the setting reaction at specified times using a differential scanning calorimeter (Differential Scanning Calorimeter, DSC 204, TASC 414/3A Controller, Netzche, Germany). Graphs of time-exothermic heat at 37℃ isothermal condition, showing the setting reaction of dental cements were plotted. Three types of luting cements studied were zinc-phosphate cement (ZPC), polycarboxylate cement (PCC), and glass ionomer cement (GIC). The effects of powder-liquid ratio on the setting characteristics of cements were also included. The amount of heat (calory) released per one gram of cement was calculated at each specified time, and was analyzed. ANOVA and Scheff's multiple comparison test (p=0.05) were used for statistical analysis using SPSS/PC+. The setting rate of cement was not constant during the setting reaction, and different setting characteristics were observed depending on the type of cement and powder/liquid ratio. Generally, 70∼90% of the setting reaction, measured by the exothermic heat release, occurred within 5 minutes after mixing. The exothermic heat released by ZPC was very high immediately after mixing, and the duration of the heat release was prolonged compared with other cements. The exothermic heat release of PCC finished most rapidly. It was generally observed that the amount of heat release (rise in temperature) per one gram of cement was highest for ZPC, followed by GIC, and then PCC. However, heat release during the first 2∼5 minutes after mixing was highest for GIC, followed by ZPC and then PCC. According to the Scheff's multiple comparison test, the duration of the total setting reaction did not show any significant difference among the cements(p>0.05), and also among the different power/liquid ratio groups(p>0.05). It was observed that more heat was released with the lower powder/liquid ratio than the higher powder/liquid ratio.

In order to investigate the relationship between methylated amino acids and diabetes, we investigated the changes of serum concentration of methylated amino acids in serum of the experimentally induced diabetic rats. The diabetic symptom was induced by injectly alloxan 100 mg/kg intraperitoneally. The serum content of N^G-monomethylarginine(MMA), N^G, N^G-dimethyl-arginine(DMA) and N^G, N^G-dimethylarginine(D'MA) were analyzed by HPLC. The results are as followings ① There was no change in serum content of MMA in the diabetic group. ② But it was observed that the amounts of DMA and D'MA were increased remarkably in the diabetic group. Specifically, D'MA content was increased about 7 times in comparision to that of the control group. ③ However, the concentration of trimethyllysine in RBC was decreased slightly in diabetic group but not significant statistically.
