  • Objectives : This study evaluates how various traditional Korean herbal medicines assess MUC5AC expression for esophageal mucosal defense and analyzes the associated mechanisms involved in inflammation. Methods : Forty types of traditional Korean herbal medicines were assessed for in vitro antioxidant activities, and the real-time PCR method was employed to analyze MUC5AC expression under pH 4.5 conditions in human esophageal epithelial cells (HET-1A). Eight types of Korean herbal medicines were evaluated for in vitro antioxidant activities, and Reactive oxygen specise (ROS) expression was analyzed under bile salt (480 𝜇M) and pH 5.5 conditions in human esophageal epithelial cells (HET-1A). Simulation experiments involving bile salts and acidity were conducted for one hour to assess the efficacy of four drugs, and the activities of Mitogen-activated Protein Kinase (MEK), Nuclear Factor Kappa B (NF-𝜅B), and Cyclooxygenase-2 (COX-2) were detected through Western blot analysis. Results : Compared to the Normal group, the Control group exhibited higher ROS generation. Such increased ROS levels were significantly reduced by four extracts: Citrus Unshius Pericarpium (CUP), Cnidium officinale Rhizoma (CR), Ginseng Radix (GR), and Linderae Radix (LR). The protein expression of COX-2 decreased with the treatment of LR, CUP, and CR. Particularly, CUP and CR exhibited superior effects compared to other groups in inhibiting the phosphorylation of NF-𝜅B. Conclusion : Based on the results obtained, we have identified drugs that inhibit oxidative stress and inflammation caused by bile acid in esophageal epithelial cells. Our future plans involve comparing and analyzing the efficacy of these herbal medicines through animal experiments.

  • It was performed to find out difference of the nutritional contents between chungjung chicken meats grown chemicals free and general chicken meats. The chungjung chicken was eat and given feeds of good quality mixed living microbial agent, power of ginseng leaves and by-product of extract liquefied sea foods from fishes producted clean area of the Western Sea, including plentiful calciums, amino acids, docosahexanoic acid(DHA) etc. Addition of they improved chungjung chicken yields and meat quality compared to general chicken given feeds mixed antibiotic etc. Also, chungjung chickens eaten miced type develop resistance to in disease. There were significant trend in crude proteins, calciums, crude lipids contents, and unsaturated fatty acids between the chungjung chicken meats and the general chicken meats. The crude proteins and calciums contents were higher in the chungjung chicken meats than the general chicken meats, but the crude lipids contents were higher in the general chicken meats than that. Also, contents of the n6 fatty acids and n3 fatty acids in chungjung meats were higher than that. Especially, contents of DHA in the chungjung chicken meats were detected higher than the general chicken meats. Therefore, the results from this experiments will provide a information for the nutritional knowledge of the 'white meats', especially the clean chicken meats.

  • Aims and Background: Traditional chemotherapy strategies for human leukemia commonly use drugs based on cytotoxicity to eradicate cancer cells. One predicament is that substantial damage to normal tissues is likely to occur in the course of standard treatments. Obviously, it is urgent to explore therapies that can effectively eliminate malignant cells without affecting normal cells. Our previous studies indicated that ginsenoside $Rg_1$ ($Rg_1$), a major active pharmacological ingredient of ginseng, could delay normal hematopoietic stem cell senescence. However, whether $Rg_1$ can induce cancer cell senescence is still unclear. Methods: In the current study, human leukemia K562 cells were subjected to $Rg_1$ exposure. The optimal drug concentration and duration with K562 cells was obtained by MTT colorimetric test. Effects of $Rg_1$ on cell cycle were analyzed using flow cytometry and by SA-${\beta}$-Gal staining. Colony-forming ability was measured by colony-assay. Telomere lengths were assessed by Southern blotting and expression of senescence-associated proteins P21, P16 and RB by Western blotting. Ultrastructural morphology changes were observed by transmission electron microscopy. Results: K562 cells demonstrated a maximum proliferation inhibition rate with an $Rg_1$ concentration of $20{\mu}\;mol{\cdot}L^{-1}$ for 48h, the cells exhibiting dramatic morphological alterations including an enlarged and flat cellular morphology, larger mitochondria and increased number of lysosomes. Senescence associated-${\beta}$-galactosidase (SA-${\beta}$-Gal) activity was increased. K562 cells also had decreased ability for colony formation, and shortened telomere length as well as reduction of proliferating potential and arrestin $G_2$/M phase after $Rg_1$ interaction. The senescence associated proteins P21, P16 and RB were significantly up-regulated. Conclusion: Ginsenoside $Rg_1$ can induce a state of senescence in human leukemia K562 cells, which is associated with p21-Rb and p16-Rb pathways.

  • Objectives : Nowadays the combined use of oriental herbal medicines and western biomedical medicines has been prevalent but controversial. Warfarin has been much reported to interact with some herbal medicines so that it influences prothrombin time(PT) & international normalized ratio(INR). This study was aimed to examine how much warfarin interacts with herbal medicines during treatment of stroke patients Methods : This was a retrospective case control study of 53 patients whowere treated with concomitant treatment of herbal medicines & warfarin. They were within normal limit in liver function, renal function, hematocrit, hemoglobin, and platelet count at first admission lab. We classified them into 2 classes: study group (taking herbal medicines including Panax ginseng, Angelica sinensis, Zingiber officinale, Salvia miltiorrhiza that were reported to interact with warfarin to impact PT (INR) and control group (taking other herbal medicines). We followed up PT (INR) at 5-10 days interval with AST, ALT, BUN, creatinine, hematocrit, hemoglobin, and platelet count. Results : AST, BUN, creatinine, hemoglobin, hematocrit, and platelet count were not changed significantly between first and final tests during the admission period. Only ALT decreased significantly in the control group. Neither baseline nor peak PT (INR) was significantly different between the groups. However, only warfarin dose was significantly correlated with PT and INR (r=0.810, r=0.798, p<0.01). Conclusions : It was concluded that PT(INR) was not influenced with herbal medicines and warfarin but by far dependent on warfarin dose in stroke patients restricted with normal liver function, renal function, and hematocrit, hemoglobin, and platelet count. Further prospective study is needed on larger samples to conclude that the combined therapy of herbal medicines and warfarin is safe.

  • Ginsenoside Rg3 is one of the active ingredients extracted from red ginseng, and it is an effective chemical component of the human body and well known in herbal medicine as a restorative agent. Several studies have shown that Rg3 has a potent anti-tumor effect on various cancer cell lines. However, Rg3-induced apoptosis in B16F10 melanoma cancer cells is not well understood. In the present study, we tested whether ginsenoside Rg3 could induce apoptosis in B16F10 melanoma cells. We found that Rg3 could inhibit B16F10 melanoma cell viability in a dose-dependent manner, but not normal cells, such as EA.hy.926 and NIH3T3 cells. We also found that Rg3 could induce apoptosis in B16F10 melanoma cells using tunnel-staining assay in a dose-dependent manner. Rg3 treatment induces the phosphorylation of p38 and the expression of Bax, but it inhibits the expressions of the phosphorylation of focal adhesion kinase Bcl2 and pro-caspase3. Taken together, our data suggest that Rg3 could be useful as an anti-cancer agent in B16F10 melanoma cells.

  • This thesis to be studied conversation by writing between the medical staff of Chosun(朝鮮) and Japan in 1763. Both countries the medical staff and intellectuals meet that communication, confrontation and conflict, exchanges and cooperation in 18C. They met greeting and sing in chorus. Chosun keep checking in western medicine of Japan. They are compared to customs of two countries. Also Japanese increase interest in the Hangeul(한글). Confrontation and conflict resulted from history recognition and difference of viewpoint of two countries. Especially Kokugaku(古學) have many influence on this situation. So battle come and go to study of Ogyu Sorai(荻生?徠) and Dajai Jun(太宰純). But this situation includes Mutual misunderstanding. Because of limitation on conversation by writing. Exchanges and cooperation take shape on the medical staff that a process of ginseng(人蔘), medical treatment. And two countries promote goodwill that method of buying books in Japan and medical treatment. In conclusion, intellectuals of Chosun and Japan have some misunderstanding and distrust. but they are communication with Chinese writing that east asian's common language. Also exchange its views and information.

  • Backgroud: Sleep deprivation (SD) impairs learning and memory by inhibiting hippocampal functioning at molecular and cellular levels. Abnormal autophagy and apoptosis are closely associated with neurodegeneration in the central nervous system. This study is aimed to explore the alleviative effect and the underlying molecular mechanism of stem-leaf saponins of Panax notoginseng (SLSP) on the abnormal neuronal autophagy and apoptosis in hippocampus of mice with impaired learning and memory induced by SD. Methods: Mouse spatial learning and memory were assessed by Morris water maze test. Neuronal morphological changes were observed by Nissl staining. Autophagosome formation was examined by transmission electron microscopy, immunofluorescent staining, acridine orange staining, and transient transfection of the tf-LC3 plasmid. Apoptotic event was analyzed by flow cytometry after PI/annexin V staining. The expression or activation of autophagy and apoptosis-related proteins were detected by Western blotting assay. Results: SLSP was shown to improve the spatial learning and memory of mice after SD for 48 h, accomanied with restrained excessive autophage and apoptosis, whereas enhanced activation of phosphoinositide 3-kinase/protein kinase B/mammalian target of rapamycin signaling pathway in hippocampal neurons. Meanwhile, it improved the aberrant autophagy and apoptosis induced by rapamycin and re-activated phosphoinositide 3-kinase/Akt/mammalian target of rapamycin signaling transduction in HT-22 cells, a hippocampal neuronal cell line. Conclusion: SLSP could alleviate cognitive impairment induced by SD, which was achieved probably through suppressing the abnormal autophagy and apoptosis of hippocampal neurons. The findings may contribute to the clinical application of SLSP in the prevention or therapy of neurological disorders associated with SD.

  • 1. Production and consumption of chemical fertilizers in Korea could be divided into five different phases of total imports, setting up fertilizer plants, self-sufficiency in production, net export, and diversification in compound fertilizers. Currently the nation has production capacity of 800 thousand M/T of nitrogen, 400 thousand M/T of phosphate ($P_2O_5$) and 200 thousand M/T of potash ($K_2O$). 2. Yearly consumption increased every year, since 1964, 28,000 M/T N, 7,700 M/T $P_2O_5$, and 7,500 M/T $K_2O$ until 1972, when the increase jumped by eight times for $P_2O_5$ and seven times for $K_2O$ for the following 3 years in anticipation of their short supply. Now total consumption has been more or less stabilized at the level of 450 thousand M/T N, 220 thousand M/T $P_2O_5$ and 180 thousand M/T $K_2O$ for the last 7 years. 3. Current operation rate of fertilizer plants is around 80% throughout the whole industry, after going through several different levels depending on demand at times. 4. Fertilizer export started in 1967 and reached a peak of 150 thousand nutrient ton in 1972, about 20% of total production, before temporarily stopping due to over-demand for next three years. The export resumed again in 1976 rise to the all time high of 670 thousand nutrient ton in 1980, almost half of total production, and then started to decline due to higher price of petroleum since then. 5. The decline in fertilizer export appears to be accelerated because several countries, in South-Eastern Asia, traditional export market for Korean fertilizers, started to build their own plants, since 1980, based on their raw materials of especially petroleum. 6. Current consumption in Korea is about 30 nutrient Kg per 10a, equivalent to that in Western European countries, partly due to new high-yielding rice varieties and extensive cultivation of fruit trees and vegetables. Additional fertilizer demand in future can be anticipated in reclaimed land for growing grass and forestry.
