  • Recent medical industry is an aging society and the application of national health insurance, with state-of-the-art research and development, including the pharmaceutical market is greatly increased. The nation's health care industry through new support expansion and improve the quality of life for the research and development will be needed. In addition, systemic administration of basic medical supplies, or drugs are needed, the drug at the same time managing how systematic analysis of pharmaceutical ingredients, based on data through the purchase of new medicines and pharmaceutical ingredients automatically classified by analyzing the statistics of drug purchases and the future a system that can predict a patient is needed. In this study, the drugs to the patient according to the component analysis and predictions for future research techniques, k-means clustering and k-NN (Nearest Neighbor) Comparative studies through experiments using the techniques employ a more efficient method to study how to proceed. In this study, the effects of the drugs according to the respective components in time according to the number of pieces in accordance with the patient by analyzing the statistics by predicting future patient better medical industry can be built.

  • Objectives: Dementia is a disease in which a person maintains a normal intellectual level during the growth period, but has acquired cognitive impairment and personality change. In this study, we tried to check whether the network pharmacology analysis method is useful in the search for herbal medicine resources for the treatment of dementia. Methods: The Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP) database is a database frequently used in Chinese medicine research. We used the TCMSP to identify herbal medicines and their molecular targets that can be used for dementia by using network pharmacology research methods. Results: It was possible to select 28 types of components that are expected to be active by applying them to the living body, and 75 types of targets that these components act on were secured. In addition, 16 kinds of drugs were identified by checking the drugs containing 28 kinds of ingredients, and it was found that Radix Salviae contained 2 kinds of the selected 28 kinds of ingredients. Conclusions: Through this study, we were able to identify ingredients, drugs, and targets that can be used for basic and clinical research on dementia.

  • A method for the determination of basic drugs based on their reaction with picric acid to form an ion-association complex extractable into several plasticizers was developed. Ba sic drugs-picric acid complexes in acid medium could be extracted quantitatively into several plasticizers except phosphates. For example, the chlorpromazine-picric acid complex showed maximum absorbance at near 410nm and was applied to extraction spectrophotometric determination of chlorpromazine. The calibration curves are linear (r>0.998) within a range from $10^{-6}to\;5{\times}10^{-4}M$ and the precision of the method was acceptable because RSD was less than 2.6% (n=7). The factors affecting the extraction system was discussed.

  • The emergence of influenza virus and antigenic drift are potential cause of world-wide pandemic. There are some commercially available drugs in the market to treat influenza. During past decade, however, critical resistances have been raised for biological targets. Because of structural complexity and flexibility of target proteins, applying a computational modeling tool is very beneficial for developing alternative anti-influenza drugs. In this review, we introduced molecular dynamics (MD) simulations approach to reflect full conformational flexibility of proteins during molecular modeling works. Case studies of MD works were summarized for the drug discovery and drug resistance mechanism of anti-influenza pharmaceuticals.

  • Many neurodegenerative diseases, such as Alzheimer's and Parkinson's disease, are devastating disorders that affect millions of people worldwide. However, the number of therapeutic options remains severely limited with only symptomatic management therapies available. With the better understanding of the pathogenesis of neurodegenerative diseases, discovery efforts for disease-modifying drugs have increased dramatically in recent years. However, the process of translating basic science discovery into novel therapies is still lagging behind for various reasons. The task of finding new effective drugs targeting central nervous system (CNS) has unique challenges due to blood-brain barrier (BBB). Furthermore, the relatively slow progress of neurodegenerative disorders create another level of difficulty, as clinical trials must be carried out for an extended period of time. This review is intended to provide molecular and cell biologists with working knowledge and resources on CNS drug discovery and development.

  • Renal dysfunction can have pronounced effects on the pharmacokinetic and pharmacodynamic characteristics of drugs. Because the exploration of these effects in patients may be limited by ethical and practical considerations, it often become necessary to perform studies on animals with experimental renal failure(ERF). ERF was produced in rats by the administration of uranyl nitrate, glycerol, salicylate, gentamicin and folate in this study. Changes in glomerular filtration rate(GFR) and renal secretion clearance of tetraethylammonium bromide$(CL^{scn}_{TEA})$, together with morphological changes of kidney cortex were evaluated and compared among ERF models. GFR(or glomeruli) and $CL^{scn}_{TEA}$(or renal tubules) were not damaged parallelly in some ERF model rats. Therefore, it seemed to be necessary to adjust dosage regimen of some basic drugs like TEA in renal dysfunction considering the functional changes of renal secretion in addition to glomerular filtration.

  • The immunomodulating effect of Salicornia herbacea polysaccharides on BALB/c mice splenocytes was investigated. Crude (CS) and fine polysaccharide (PS) extracts with potential biological activity were prepared from S. herbacea. For in vitro experiments, splenocytes and separated T cells were treated with CS and PS (0.5, 1, 2, and 4 mg/mL). For in vivo experiments, the CS and PS were orally administered to BALB/c mice every day for 2 weeks. For basic data analysis, physiological parameters were recorded. Cell proliferation of splenocytes and T cells was used as an index for immunomodulating activity. The proliferation of splenocytes and separated T cells was 3.2 and 3.5 times higher than the control, respectively. Moreover, when splenocytes were treated with mitogen, the highest proliferation rate was observed in splenocytes cultured with PS. Interestingly, the stimulative activity of PS was more strongly exerted through $CD4^+$ T cells than through $CD8^+$ T cells.

  • The purpose of this study was to evaluate the predictability of the fraction of drug absorbed in humans using the immobilized artificial membrane phosphatidylcholine column (IAMPC) under optimized conditions in comparison with a conventional IAMPC method. Twenty commercial drugs, both acidic and basic in nature, were used in the study, Drugs were dissolved in acetonitrile:water (50:50, v/v) at a concentration of 100 mg/ml, and were injected on HPLC/UVD at a mobile phase (acetonitrile:DPBS = 10:90,v/v) with a flow rate of 0.5 ml/min equilibrated at 37$^{\circ}C$.
