Particulate matter (PM) is known to be involved in the onset and progression of various diseases by promoting oxidative and inflammatory reactions as air pollutants containing various small particles that are harmful. In this study, the protective efficacy of herbal medicines was evaluated in human corneal epithelial cells (hCECs) to select natural products that can protect the eye, the primary organ directly exposed to external pollutants from PM. As a result, five candid ate herbal medicines [Cheonmundong, Asparagus Rhizome; Seokchangpo, Aciru Gramineri Rhizoma; Hwangryeon, Coptidis Rhizoma; Gamgug, Chrysanthemi Indici Flos; and Geumjanhwa (Marigold flower petals)] which showed inhibitory efficacy on PM_2.5-induced cytotoxicity, were selected from among 12 candidate herbal medicines. To evaluate the antioxidant activity of these candidate substances, the reactive oxygen species (ROS) scavenging ability was investigated, and it was found that the extracts of Seokchangpo, Cheonmundong and Hwangryeon showed a significant inhibitory effect on PM_2.5-induced ROS production, which was correlated with the preservation of mitochondrial activity. In addition, it was confirmed that they could block DNA damage caused by PM_2.5 through analysis of 8-hydroxy-2'-deoxyguanosine generation and phosphorylated-H2A histone family member X (γ- H2AX) expression. Furthermore, the increase in inflammasome activity and inflammatory response in PM_2.5-treated hCECs was also canceled in the presence of these extracts. Although additional studies are needed, the results of this study will be used as primary data to find novel natural compounds that protect hCECs from PM.

In many cases of human cancer, the appearance of hypersialylated glycan structures is related to a precise stage of the disease ; this may depend on the elebated sialyltransferase activity during carcinogenesis. The aim of this study was to investigate the inhibitory effects of Oriental medicinal herbs on enzymatic activities of two kinds ofsialyltransferase, Gal $\beta$ 1,3GalNAc$\alpha$2,3-sialyltransferase(ST3Gal I) and Gal $\beta$ 1,4GlcNAc $\alpha$2,6-sialyltransterases(ST6Gal I), which are well known as glycosyltransterases associated with cancer. The aqueous extracts of Scutellaria Baicalensis Georgi, Coptidis Rhizoma, Glycyrrhiza urlensis Fisch, Bupleuri Radix and Platycodi Radix were prepared and tested, respectively. At concentration of 100$\mu$g, Glycyrrhiza uralensis Fisch showed the highest inhibitory effects(about 42% and 57%, respectively) on ST3Gal Iand ST6Gal Iactivities. ST3GAl I was inhibited about 23% by Scutellaria baicalensi G댁햐, but not by the other samples, whereas ST6Gal I was inhibited about 20% and 40%,respectively, by Scutellaria baicalensis Georgi and Bupleuri Radix. All inhibitory effects were obtained in a concentration-dependent manner.

Objectives : Acne, one of the most common disorders in dermatology clinic, is a chronic inflammatory disease which has the symptoms of comedones, papules, pustules, cysts, nodules and scars mainly on the face. Although some of pathologic findings are suggested, but the exact causes and mechanisms are not yet known in Western Medicine. Hwangryeonhaedok-Tang(HRHDT) is an antiinflammatory, antipyretic and detoxifying herb decoction. In this report, we would like to share our experience of acne treatment with HRHDT. Methods : We had treated several patients with acne, facial flushing and uprising febrile sensation on face using oral administration and external application of HRHDT. HRHDT is basically made up with Scutellariae Radix, Coptidis Rhizoma, Phellodendri Cortex and Gardeniae Fructus. In this trial, several other herbs were added according to the individual patient's accompanying symptoms. After the decoction of herbs in amount for 10 days, $Yogourmet^{(R)}$ Kefir Starter 10 g was added to the herbal solution that was then fermented in an incubator at $25^{\circ}C$ for 72 hours, and divided into 30 doses. Results : Photographies were taken before and after the treatment. The severities of acne were evaluated with these photos according to the Korean Acne Grading System(KAGS). As results, we observed dramatic clinical improvements and the decreases of KAGS grades after the average treatment period of 8 weeks. The medication was orally administered 3 times a day and the external treatment was applied average twice a week during the whole treatment period. Conclusions : From these results, HRHDT may be considered as a good prescription for the febrile and toxic type of acne patients.

Objectives : Berberine, a main alkaloid component of Coptidis rhizoma, has an antimicrobial and anti-tumor activities and antiinflammatory effect. In the present study, we investigated effect of berberine on the production of inflammatory mediators such as nitric oxide(NO), prostaglandin E2(PGE2), TNF-${\alpha}$ and IL-1${\beta}$ in LPS-stimulated BV2 microglial cells, Methods : BV2 cells were pre-treated with berberine and then stimulated with LPS. The cytotoxicity of berberine was determined by MTT assay. The NO production was measured by Griess assay. The mRNA expression and protein levels of inducible nirtic oxide synthase(iNOS) were determined by RT-PCR and Western blot. The production of PGE2 and cytokines was measured by ELISA. Results : Berberine inhibited the production of NO, PGE2 and pro inflammatory cytokines, TNF-${\alpha}$ and IL-1${\beta}$ in a dose dependent manner in LPS-stimulated BV2 cells. In addition, berebrine greatly suppressed the mRNA expression and protein levels of iNOS and inflammatory cytokines induced by LPS stimulation. These results indicate that the post-transcriptional regulatory mechanism of iNOS and/or inflammatory cytokine gene expression by berberine is involved in its anti-inflammatory effects, respectively. Conclusion : The present study suggests that berberine can be useful as a potential anti-inflammatory agent for treatment of various neurodegenerative diseases such as Alsheimer's disease, Parkinson's disease and stroke.

A study was carried out to investigate the possibility of acclimation of Coptis japonica Makino in Korea. Coptis japonica could be grown within 4 years as a medicinal crude drug if it is cultivated in the area of mountain facing north(300m above sea level) with 70% light interception and appropriate soil texture. It is to be noted that the propagation of the plant is more important than the yield of berberine because the berberine contents do not change in different conditions. The results were as follows; 1. The germination rates of the seeds by covering with the pine tree leaves were the highest and averaged 63%. 2. The germination rates of dry seeds were not affected in spite of low temperature and $GA_3$ treatment. 3. The germination rates of the seeds stored in moistured sand were averaged 85%, but in dry state, they were not germinated. 4. The number of leaves and fresh weight of Coptis japonica from the area of mountain facing north were increased significantly. 5. The growth and fresh weight of Coptis japonica were reduced in clay. 6. The best growth was obtained under 70% light interception. It is possible to intercrop between evergreen trees. 7. The foliage dressing did not affect the growth. 8. The number of leaves and fresh weight were increased from the 3rd year, and the average weight of rhizomes was 5.7g in 4th year. 9. The berberine contents of the rhizomes of Coptis japonica under various treatment conditions ranged from 9 to 10%. Coptidis Rhizoma from this study and from Korean market showed much higher berberine contents than those from Japanese market.

Objective: The main purpose of this work was to investigate the effect of berberine hydrochloride (BH) on the proliferation, apoptosis, migration, and invasion of CNE-1 nasopharyngeal carcinoma cells. Our results shed light on the functional components of traditional Chinese herbs for potential use in modern medicine. Methods: The CNE-1 cell line was treated with different concentrations of BH and effects on cell viability and proliferation were evaluated using the Cell Counting Kit-8 (CCK-8) assay. Anti-migratory and anti-invasive actions of BH were investigated using wound healing assays and the Millicell Hanging cell culture insert system, respectively. Expression of the epithelial-mesenchymal transition (EMT)-related gene twist (Twist) was analyzed by real-time PCR and Western blotting. Apoptosis was estimated with an annexin-V fluorescein (FITC) apoptosis detection kit, as well as with reference to levels of activated caspase-3 of CNE-1 cells before and after treatment with BH utilizing fluorescence spectroscopy. Results: BH was capable of reducing proliferation and viability of CNE-1 cells in a dose- and time-dependent manner, also demonstrating anti-migratory and anti-invasive capacities which correlated with reduction in expression of Twist. Finally, BH was able to induce significant amounts of apoptosis in CNE-1 cells, as demonstrated by an increase in the activity of caspase-3 and in annexin-V staining following treatment. Conclusion: BH extracted from rhizoma coptidis demonstrated an ability to block proliferation, induce apoptosis, and impair the migration and invasion of the CNE-1 cell line Considering these properties, our results suggest that BH could be an important compound for consideration in the treatment of nasopharyngeal carcinoma.
