Background: Studies have suggested that the northern provinces of Gangwon-do are good sites for licorice (Glycyrrhiza uralensis Fisch.) cultivation in Korea, as they have similar temperatures to its original locations in northern China. However, poor growth and freezing injury are often reported in Korea. Therefore, it is necessary to reassess the domestic cultivation site of licorice. Methods and Results: To determine the optimum temperature for cultivating licorice, the growth, yield, and pharmacological characteristics of G. uralensis were assessed in a temperature gradient tunnel at Eumseong, Chungcheongbuk-do, Korea in 2017. Plant height increased until the temperature rose to $5.9^{\circ}C$ above the local external temperature. Yield (㎏/10a) increased by 46.9% when the growing temperature was $1.5^{\circ}C$ to $3.0^{\circ}C$ (T2) above the external temperature and by 72.6% when the growing temperature was $3.0^{\circ}C-4.5^{\circ}C$ (T3) above the external temperature. However, a difference of $4.5^{\circ}C-5.9^{\circ}C$ (T4) above the external temperature, decreased the yield by 9.8% compared to that at T2. The glycyrrhizin content of G. uralensis roots in each temperature band was 0.72%, 0.53%, 0.91%, and 0.84% (T1, T2, T3, T4), these differences appear to result form individual plant variation rather than growth temperature. Conclusions: Based on the results of this study, we estimate that the temperature-based optimum cultivation site for G. uralensis in Korea is the south central region, rather than the northern province of Gangwon-do. Improvement in growth and yield maybe observed if the plantations in the central Jecheon (Chungcheongbuk-do, Korea) are expanded into the south central region.

20S-dihydroprotopanaxadiol (2H-PPD) is a derivative of protopanaxadiol, a glycone of ginsenosides prepared from Panax ginseng. Although ginsenosides and acidic polysaccharides are known to be major active ingredients in ginseng, the immunopharmacological activities of their metabolites and derivatives have not been fully explored. In this study, we aimed to elucidate the regulatory action of 2H-PPD on the function of monocytes and macrophages in innate immune responses. 2H-PPD was able to boost the phagocytic uptake of fluorescein isothiocyanate-dextran in macrophages and enhance the generation of radicals (reactive oxygen species) in sodium nitroprusside-treated RAW264.7 cells. The surface levels of the costimulatory molecules such as CD80 and CD86 were also increased during 2H-PPD treatment. In addition, this compound boosted U937 cell-cell aggregation induced by CD29 and CD43 antibodies, but not by cell-extracellular matrix (fibronectin) adhesion. Similarly, the surface levels of CD29 and CD43 were increased by 2H-PPD exposure. Therefore, our results strongly suggest that 2H-PPD has the pharmacological capability to upregulate the functional role of macrophages/monocytes in innate immunity.

Objectives : In this study, I want to work on efficacious porridges through inquiry into the Jukmiryu(粥穈類) based on the classical literature. It is intended to serve as a basic study to explore the modern-day application of dishes that are good as patient meals or healthy foods for elderly people. Methods : I have taken the original text of Jukmiryu(粥穈類) included in Junsaengpaljeon(遵生八牋) and translated it. Further, I have compared it to those porridges treated in Nonohangeon (老老恒言), a book in geriatrics from Ming Dynasty. Results : Nonohangeon(老老恒言) describes sources and effects of 100 porridges. With recipes too simplified, however, it doesn't provide any practical help. In contrast, Junsaengpaljeon(遵生八牋) presents 40 porridges together with their effects and recipes. It is practically more beneficial, as it provides recipes more specific than Nonohangeon(老老恒言). Conclusions : Jukmiryu(粥穈類) in Junsaengpaljeon(遵生八牋) set great store on the pharmacological effects of food. As it provides detailed description of porridge recipes and ingredients as well as their effects, readers can easily apply them to symptoms. Since individuals may choose what would be appropriate for their own symptoms, it could be helpful in not only providing patient meals and foods for elderly people but also improving dietary practice.

General pharmacological properties of ADP, a new pharmaceutical composition, which contains a mixed water extract obtained from the mixture of Phellodendron cortex (Phellodendron amurense) and Anemarrhena rhizoma (Anemarrhena asphodeloides), as the active ingredients, were investigated in experimental animals administering orally and in vitro test system. ADP had no influences on general behavior, pentobarbital sleeping time, spontaneous motor activity, motor coordination of mice, normal body temperature, chemoshock produced by pentylenetetrazole and writhing syndromes induced by 0.8% acetic acid at the dose of 150 and 1500 mg/kg. Gastric secretion of rats and intestinal motility of mice were not also influenced by the administration of ADP at doses of 150 and 1500 mg/kg, with the exception of the significant decrease of free HCI concentration at a dose of 1500 mg/kg in rats. ADP (150 and 1500 mg/kg) did not alter mean arterial blood pressure and heart rate in conscious rats. ADP given to anesthetized rats showed no effect on respiratory rate at the same doses. In in vitro experiments, ADP at the concentration of 150 mg/L did not show direct effect and inhibitory or augmentative action on histamine- or acetylcholine-induced contractions in the isolated ileum of guinea-pig. Taken together, these results indicate that ADP does not induce any adverse effects in experimental animals.

Effects of Oplopanax elatus have known to various pharmaceutical therapies. However, chemical prosperities in the plant are rarely investigated. In order to detect biological activity, we evaluated the antioxidant activity of five fractions from methanolic extracts in each part of O. elatus. Also, contents of polyphenols and polysaccharides were measured. Five fractions were of sub-fractions using n-hexane, ethyl-acetate, n-butanol, and water from methanolic extracts. Ethylacetate and n-butanol fractions from stem and root exhibited strong antioxidant activity and high total phenolics content. On the HPLC analysis, ten free phenolics, including p-hydroxybenzoic acid, chlorogenic acid, caffeic acid, syringic acid, p-cou maric acid, ferulic acid, naringin, hesperidin, quercetin and trans-cinnamic acid, were identified from the fractions and were shown to different quantitative proportions. Furthermore, ethylacetate and n-butanol fraction had the highest amount of chlorogenic acids, one of the cinnamic acid derivatives possessing pharmacological properties. These results indicated that the fractions of O. elatus, as well as methanolic extracts, could be used as natural antioxidative ingredients.

Ganoderma lucidum has been widely used not only as ingredients in herbal medicine but also in pharmacological soft drinks. The author collected for analysis of content of 8 kinds of heavy metal(Cd, pb, Hg, Cu, Mn, Fe, As) in soil and cluture soil in an around the Taegu area including Sang Ju, Non Gong, Keum Ho, and Weol Bae. THe toxic content in Gaoderma lucidum showed relatively low level as in cadmium lead mercury arsenic : 0.8-0.13ppm 0.17-1.43ppm 0.02-0.32ppm 0.01-0.19ppm respectively : in copper mangenese zinc and iron : 0.93-4.29ppm, 0.37-2.18ppm 1.02-1.65ppm, 4.57-11.04ppm those grown in soil showed higher percentages of content than those grown on logs in lead copper zinc and iron by 43.2% 68.6%, 20.3% and 43.2% respectively. The content of heavy metals in those grown in soil and culture soil tended to be higher in the areas near factories of industrial complexes especially in manganese and iron. The content of heavy metals in soil and culture soil appeared lower than the mean values of Korean Soil. No interrelationship was found in the content of heavy metals between those of Ganoderma lucidum grown on logs and those grown in soil. In case of pot cultivation however the mushroom spawns are grown originally in soil which seems to influence the degree of content of heavy metals of media.

The youngkaechulgamtang (Y) composed of four herb drugs, including Hoelen (H). Cinnamomi Ramulus (C). Atractylodis Rhizoma Alba (A) and Glycyrrhizae Radix (G). In oriental medicine literatures, Youngkaechulgamtang is described to be effective in headache, inflammation, uremia, gastritis, diarrhea and hypertension. To estimate the clinical effectiveness of Youngkaechulgamtang, several pharmacological experiments were carried out. The results are summerized as follows; On acetaminophen-induced hepatotoxicity, C+A, Y-G, Y-H, MIX and Y showed the significant elevation of glutathione-S-transferase. But, C+A, Y-G, Y-H, MIX and Y showed the significant suppression of serum aminotransferases. On ANIT-induced cholestasis, U (Ursodesoxycholic acid 50 mg/kg)+$Y_l$ (760 mg/kg) showed the significant increase of bile juice volume. $Y_l,\;Y_2$ (1520 mg/kg), U, $U+Y_l$ showed the remarkable increase of cholic acid. U and $U+Y_l$ showed the significant decrease of total bilirubin. From these results, it is suggest that Y shows liver protective effect against various hepatic injury. Especially, Youngkaechulgamtang was more effective than mixture of 4 ingredients in the elevation of glutathione-S-transferase in acetaminophen-induced hepatotoxicity.

Objectives : Network pharmacology analysis is commonly used to investigate the synergies and potential mechanisms of multiple compounds by analyzing complex, multi-layered networks. We used TCMSP and BATMAN-TCM databases to compare results of network pharmacological analysis between White Ginseng(WG) and Red Ginseng(RG). Methods : WG and RG were compared with components and their target molecules using TCMSP database, and compound-target-pathway/disease networks were compared using BATMAN-TCM database. Results : Through TCMSP, 104 kinds of target molecules were derived from WG and 38 kinds were derived from RG. Using the BATMAN-TCM database, target pathways and diseases were screened, and more target pathways and diseases were screened compared to RG due to the high composition of WG ingredients. Analysis of component-target-pathway/disease network using network analysis tools provided by BATMAN-TCM showed that WG formed more networks than RG. Conclusions : Network pharmacology analysis can be effectively performed using various databases used in system biology research, and although the materials that have been reported in the past can be used efficiently for research on diseases related to targets, the results are unreliable if prior studies are focused on limited or narrow research areas.

Phytoestrogens exist in edible compounds commonly found in fruits or plants. For long times, phytoestrogens have been used for therapeutic treatments against human diseases, and they can be promising ingredients for future pharmacological industries. Kaempferol is a yellow compound found in grapes, broccoli and yellow fruits, which is one of flavonoid as phytoestrogens. Kaempferol has been suggested to have an antioxidant and anti-inflammatory effect. In past decades, many studies have been performed to examine anti-toxicological role(s) of kaempferol against human cancers. It has been shown that kaempferol may be involved in the regulations of cell cycle, metastasis, angiogenesis and apoptosis in various cancer cell types. Among them, there have been a few of the studies to examine a relationship between kaempferol and apoptosis. Thus, in this review, we highlight the effect(s) of kaempferol on the regulation of apoptosis in diverse cancer cell models. This could be a forecast in regard to use of kaempferol as promising treatment against human diseases.

Panax ginseng root has been used as a major source of ginsenoside throughout the history of oriental medicine. In recent years, scientists have found that all of its biomass, including embryogenic calli and flower buds can contain similar active ingredients with pharmacological functions. In this study, transcriptome analyses were used to identify different gene expressions from embryogenic calli and fl ower buds. In total, 6,226 expressed sequence tags (ESTs) were obtained from cDNA libraries of P. ginseng. Insilico analysis was conducted to annotate the putative sequences using gene ontology functional analysis, Kyoto Encyclopedia of Genes and Genomes orthology biochemical analysis, and interproscan protein functional domain analysis. From the obtained results, genes responsible for growth, pathogenicity, pigments, ginsenoside pathway, and development were discussed. Almost 83.3% of the EST sequence was annotated using one-dimensional insilico analysis.
