Hyeonggaeyeongyo-tang (HYT; Jingjielianqiao-tang), is known to be effective in lowering wind-heat blended as a pathogen of kidney. HYT has been traditionally used for the treatment of a syndrome in kidney meridian, due to invasion of pathogenic wind and heat. Nowadays, this prescription is used to treat diseases marked by excessive wind and heat in the kidney meridian, such as acute otitis media, empyema, hypertrophic rhinitis, nasal bleeding, nasal obstruction, acne and tonsillitis. The present study was conducted to evaluate the effect of HYT on the regulatory mechanism of cytokines and nitric oxide (NO) for the immunological activities in Raw 264.7 cells. After the treatment of HYT water extract, cell viability was measured by MTT assay, NO production was monitored by measuring the nitrite content in culture medium. Cyclooxygenase-2 (COX-2_ and inducible nitric oxide synthase (iNOS) were determined by immunoblot analysis, and levels of cytokine were analyzed by sandwich immunoassays. The production of No was significantly inhibited by pre-treatment (1h) with HYT(0.1-0.3 mg/ml) on LPS-activated Raw264.7 cells. The expression of iNOS and COX-2 protein were up-regulated by LPS, but the increased levels of iNOS and COX-2 were inhibited by pre-treatment of HYT (0.3-1.0 mg/ml), respectively. And the level of interleukin-6 (IL-6), cytokine released from macrophage, was reduced by HYT pre-treatment (0.3-1.0 mg/ml). Thus, the present data suggest that HYT may play an important role in adjunctive therapy in Gram-negative bacterial infections.

A new medical system was started in Korea in 2000 and pharmaceutical affairs law was revised in 2001. According to the revised law, generic substitution is permitted only to the drug products which are proven to be bioequivalent to the reference listed drugs. To expand the list of bioequivalence-proven drug products and to ensure the credibility of the therapeutic equivalence of generic drug are the hot issues in Korea. Also, the KFDA has a plan to revise the pharmaceutical affairs law that bioequivalence reports of all the generic prescription drug products should be submitted to the KFDA for drug approval after July in 2004. Therefore, it is increasing the necessity to develop the bioequivalence-demonstrating methods for specific drug substances and preparations which require to conduct food-effect bioavailability or bioequivalence study. There are some differences between US and Japanese guidances of food-effect bioavailability and bioequivalence studies. In this paper, we examined the recently published US guidance about food-effect study and it will be a reference to make our own guidance about food-effect bioavailability and bioequivalence guidances in Korea.

Scoparone is a major component of the shoot of Artemisia capillaris (Compositae), which has been used for the treatment of hepatitis and biliary tract infection in oriental countries. In the present study we observed that, scorparone exhibited no cytotoxic effect in unstimulated macrophages, but reduced the release of nitric oxide (NO) and prostaglandin $E_2\;(PGE_2)$ upon stimulation by IFN-${\gamma}$/LPS or LPS. The inhibitory effects were found to be in conjuction with the suppression of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) in IFN-${\gamma}$/LPS stimulated RAW 264.7 cells. Moreover, scoparone also attenuated the production of tumor necrosis factor (TNF)-${\alpha}$, interleukin (IL)-$1{\beta}$ and IL-6 in LPS-stimulated RAW264.7 cells. These results suggest that scoparone decreases the production of the inflammatory mediators such as NO and $PGE_2$ in macrophages by inhibiting iNOS and COX-2 expression.

Purpose: Recent investigations suggest that the antiplatelet effect of clopidogrel may be decreased when this medication is taken together with certain proton pump inhibitors (PPIs). However, there has been no study conducted in Korea regarding the clinical effect of clopidogrel-PPI interaction. This study targeted patients who received stents to investigate the effect of the concomitant use of clopidogrel and PPIs on the occurrence of adverse cardiovascular events in Korean patients. Methods: The patients who received a stent insertion at the Yeouido St. Mary's Hospital between January 2010 and April 2011 were included. The patients were divided into two groups, clopidogrel and clopidogrel + PPI, and followed for 12 months after the date of stent insertion using prescription history and medical records. The recurrence rates of the cardiovascular events among the two patient groups were statistically analyzed. Results: There was no difference between the two groups in the basic characteristics of the 157 patients in the clopidogrel group and the 62 patients in the clopidogrel+PPI group. Simple logistic regression showed a significantly higher rate of re-hospitalization in the clopidogrel+PPI group (OR=1.893, 95% CI 1.040-3.445, p=0.037). However, the results of the multivariate logistic regression of the variables found to have statistical significance by crosstabulation showed no significant difference in the rate of adverse cardiovascular events or re-hospitalization between the two groups. Conclusions: There was no significant difference between the clopidogrel and clopidogrel+PPI group among new patients with cardiovascular stents with respect to the occurrence of revascularization procedures, stent thrombosis, or chest pain, or with respect to the re-hospitalization rate for all cardiovascular events.

To idenifty effect of Bojungbangam-tang kakambang on Cisplatin-Induced G2/M Phase Arrest in Human Renal Proximal Tubular HK-2 Cells. Cytotoxicity of cisplatin was detected in HK-2 cells and the value of IC50 is about $25\;{\mu}M$. The treatment of cisplatin to HK-2 showed the G2/M phase cell cycle arrest. The ethanol extract of Bojungbangam-tang kakambang (EBTKB), a new herbal prescription composed of ten crude herbs, inhibited cisplatin-induced G2/M phase arrest in HK-2 cells. EBTKB increased G0/G1 peak in cisplatin-treated HK-2 cells. p53, p21 and p27 expression were increased in cisplatin-treated HK-2 cells. Inhibitory effect of EBTKB on cisplatin-induced G2/M phase arrest was accomplished through inhibition of p53, p21 and p27 expression. Also, reduced CDK2 and cyclin A expression by cisplatin were increased by EBTKB, but cyclin E was not changed. Reduction of ERK activation and increment of p38 activation by cisplatin were increased ERK activation and decreased p38 activation by EBTKB. Cisplatin had no effect on JNK activation, but EBTKB increased JNK activation. These results can suggest that EBTKB inhibits cisplatin-induced G2/M phase arrest in HK-2 cell through reduction of p53-dependent p21 and p27 protein, ERK activation and p38 inactivation.

Bonchoyuham Nyoryeong(本草類函要領) shows how Donguibogam(東醫寶鑑) -Mirror of Eastern Medicine- is understood, digested into Korean medicine, and at the same time how it participated in the historical shaping of Korean medicine since the publishing in the early 17th century. The author, Hyeon Jae-deok, internalized the structure, content, and significance of Donguibogam and drew out a novel, concise, but comprehensive type of medical manual, while many other medical books since the 17century in Korea are estimated to have been an abridged edition of the Donguibogam. It may well be estimated as exemplar of the extent to which Donguibogam informed Korean medicine since the 17 century. The book shows as well how Bencao Gangmu(本草綱目) -Compendium of Materia Medica- and Donguibogam are merged and set a new medical stream in the 19th century Korea. Hyeon Jae-deok looked at the Bencao Gangmu from the lens of clinical treatment and prescription such that he focused on sections, elements, or parts of procedures, treatments, and prescriptions, not on the herbal taxonomic knowledge of the book. This perspective was embodied in Bonchoyuham(本草類函), which cited simple remedies, prescriptions, or treatments from Bencao Gangmu.

It is the well-known truth that processing of raw information is needed to a certain extent during information search. Especially for Oriental Medical information, it becomes much clearer that even more complex processing is necessary. As a means of reducing such complexity, this study suggests a way to understand effectively the organic relationships among information found on the interface. In this process, 'knowledge-based archaeological' method has been used. A new concept of interface observed by this research is the study of a system which contains realistically considered knowledge-based archaeological and historical specificity. These models are organized so that search results could be materialized in different tree-structured interface models, which can help one understand the relationships among wanted search results at one glance and confirm the details of those results via mouse click. Strength of the vertical tree structure resides in its capability of suggesting its users clear historical relationship between separate Oriental medical information. The horizontal tree structure enables deeper understanding of sectional interrelationship of searched information. The strength of the prescription tree structure is that it helps one understand the lineage of prescriptions, as Oriental medicinal treatment is often summarized into changes in prescriptions.

After new medical system of separation of dispensary from medical practice was started in 2000 in Korea, to expand bioequivalence-proven drug products and to ensure the credibility of the therapeutic equivalence of generic drugs are hot issues in Korea. It will be obligatory to submit bioequivalence reports for getting licenses of all generic prescription drugs in the near future. Like other countries such as US and Japan, the KFDA also has a plan to re-evaluate the already approved drugs by bioequivalence studies. Therefore, it becomes more necessary to develop bioequivalence-demonstrating methods for specific preparations such as topical drug products among already approved drug products. There are some differences between US and Japanese guidances of bioequivalence studies of generic drug products for topical use. The information on Japanese guidance and the guidance's Q&As is already provided in our previous paper. In this paper, we examined the US guideline published in 1995 and compared with the Japanese guideline, which will give a useful information to make a guidance on bioequivalence studies of topical drug products in Korea.
