Dengropanax morfiferus (D), Broussonitia kazinoki (B), and Cudriania tricuspidata (E), a widely cultivated species in South Korea, has been used as traditional medicine to treat numerous diseases. In this study, we evaluated the antidiabetic effects in a various signaling mechanisms using mixed extract and major component contents were analyzed by HPLC in the combined extracts from Dengropanax morfiferus, Broussonitia kazinoki, and Cudriania tricuspidata (DBCE). DBCE inhibited ${\alpha}$-glucosidase and ${\alpha}$-amylase activation and showed potent antioxidant effects, which are evaluated using DPPH, ABTS, and SOD assay. Cytokines, which are released by inflammatory cells in pancreatic islets, are involved in the pathogenesis of type 1 diabetes mellitus. DBCE showed the protective effects in RINm5F cells against cytokines-induced damage by suppressing inducible nitric oxide (NO) synthase and COX-2 expression and NO production. Insulin resistance is the primary characteristic of type 2 diabetes. Therefore, the regulatory effect of DBCE on glucose uptake and production are investigated in insulin-responsive human HepG2 cells. DBCE stimulated glucose uptake, prevented Glut2 and phosphor-IRS1 downregulation induced by high glucose (HG, 30 mM). Moreover, DBCE pretreatment diminished glucose levels, PEPCK and G6Pase overexpression provoked by HG. These findings suggest that DBCE might be used for diabetes treatment through alpha-glucosidase or alpha-amylase activity regulation, pancreatic beta cell protection, hepatic glucose sensitivity improvement. Cytokines, which are released by inflammatory cells' infiltrations around the pancreatic islets, are involved in the pathogenesis of type 1 diabetes mellitus.

Objectives : We tried to establish standards for genuine by discriminating 3 kinds of pollen and spore herbs that are highly to be mixed with each other. Using an scanning electron microscope, we prepare a standard for discriminating external morphological characters of minute herbs, thereby contributing to the stable supply of genuine herbal medicines. Methods : Standard samples were confirmed by literature review on external morphological characteristics of original plants and herbal medicines, and collection and identification of original plants. The herbal medicines on the market were purchased and classified with using naked eye observation and magnifier. Finally, micromorphological identifications were conducted using an scanning electron microscope. Results : 1. Pini Pollen was clearly distinguished by its relatively medium size and a pollen grain with two swollen reticulate sacci at both ends. The verrucate ornamentation on the exine surface of the corpus and a sunken leptoma germ pore may be used as a discrimination criteria. 2. Typhae Pollen was distinguished by its relatively small size and a saccus on the end of a pollen grain. Reticulate ornamentation of exine surface of the corpus, and a slightly clear ulcerate germ pore can be used as a discrimination criteria. 3. Lygodii Spora was distinguished by its relatively large triangular-ovate shape and trichotomous fissure. Verrucate-tuberculate ornamentation of exine surface and trilete aperture could be used as a discrimination criteria. Conclusion : These results indicate that the use of electron microscopy is very effective for discriminating the external morphology of minute herbal medicines.

Herbal medicines have been used since ancient times as medicines to treat and relieve the symptoms of many different human diseases. However, so far, relatively few herbal medicines have been evaluated scientifically to prove their safety, potential benefits and effectiveness. This study was conducted to provide the groundwork for improving the current registration regulations for herbal medicines in distinction from synthetic medicines. The study was performed based on the literature research and individual interviews with 5 experts who had extensive experience in registration of herbal medicines. When compared with synthetic drugs, herbal medicines exhibit some marked differences, namely the active principles are frequently unknown, standardization, stability and quality control are not easy, they are usually mixtures of complex compounds. Second, the current regulations for herbal medicines are reviewed by comparison of foreign regulation systems like the one in China. The regulation requirements of herbal medicine in China are in distinction from synthetic drugs. The authors conclude that new registration requirements for the herbal medicines should be changed as follows; the toxicity and efficacy data should be submitted as mixed herbal preparation and the documents and other research on the reproduction and generation toxicity need to be shown for the proof of reproduction and generation toxicity, if needed.

Objective : Herbal processing is one of the traditional techniques used in Korean medicine to increase the effectiveness of herbs or reduce their toxicity. In this study, Gardeniae Fructus processed with ginger juice and alcohol was prepared to evaluate the anti-inflammatory effect on lipopolysaccharide (LPS)-induced macrophages. Methods : The processing of Gardeniae Fructus was performed by adding 40 % ginger juice or 10% alcohol to the total weight of Gardeniae Fructus and then roasting at 150℃ for 5 minutes. Cell viability was determined by 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. To detect nitric oxide (NO) production, culture media were mixed with Griess reagent and measured the absorbance at 540 nm. Prostaglandin E₂ (PGE₂) and pro-inflammatory cytokines were detected by enzyme-linked immunosorbent assay (ELISA). Western blot was applied to monitor protein expression levels. Results : LPS-induced NO, PGE₂ and inflammatory cytokines were decreased by the treatment of normal or processed Gardeniae Fructus ethanol extracts (GFE). Compared to normal GFE, the processed GFE showed a stronger inhibitory effect on the production of NO and PGE₂. These inhibitory effect of GFE was due to the suppression of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) mediated from the inhibition of nuclear factor kappa B (NF-κB). Furthermore, processed GFE showed more suppressive effects on the expression of iNOS, COX-2 and IκBα proteins than normal GFE. Conclusion : From these results, it was concluded that GFE had an improved anti-inflammatory effect compared to normal GFE. These results provide an objective evidences for the use of herbal processing in Korean medicine.

Objectives : The purpose of this study was to confirm whether Codonopsis Radix(CR) could be used in the same way for expected indications or diseases of adaptation instead of Ginseng Radix(GR), which acts as a principal herb in Sagunja-tang. Methods : The Traditional Chinese Medicine Systems pharmacology(TCMSP), a database for the study of systems biology related to Chinese medicine, screened potential active compounds in each quartet. By searching for all the proteins that each compound provides, the target of Sagunja-tang with GR(GRST) and the target of Sagunja-tang with CR(CRST) were compared using the network analysis method, and the top ranked target of each serving was selected. Results : Through TCMSP, a Chinese medicine database, the potential effective ingredients of GRST or CRST screened, and the target proteins related to these substances were found to be the most affected by Glycyrrhizae Radix et Rhizome, an herbal medicine mixed in Sagunja-tang, and the target diseases were the same. And the same were found for the target protein, gene and target diseases of GRST and CRST. Conclusions : The prescription with similar composition is likely to have similar network pharmacology analysis results, and the analysis result may be controlled by the herbal medicines which are assumed to be the main function. Therefore, rich and reproducible basic studies is more important because network pharmacological studies can be dominated by data that has been done a lot of previous studies.
