Objectives: Ukgan-san does not appear in Traditional Korean Medicine classics. However, it has been used in research and clinical applications in Korea. In this paper, we are aiming to examine the records concerned with Ukgan-san to the present, and announce the present usage state in Korea. Methods: We searched and summarized the contents of previous medical books about Ukgan-san. In order to investigate the current status of utilization of Ukgan-san in Korea, a bibliographic database of Korea, a database of clinical researches, and a database of pharmaceuticals of the Korea Food and Drug Administration were searched. Results: As a result of searching Ukgan-san related documents, Ukgan-san has been developed in China (Ming dynasty). However, its clinical application has been expanded by modern Japanese kampo medicine doctors. In Korea, cases of Parkinson's disease, other movement disorders, and psychiatric disorders have been reported, and randomized controlled trials had been done and planned. In addition, some extracts which are consisted of Ukgan-san are also available. Conclusions: In Korea, Ukgan-san has been influenced by Japan and has been used for clinical and research purposes. The utilization rate in Korea is still small, but the utilization rate will increase according to the results of clinical studies.

Paradoxical response refers to the enlargement of old lesions or unexpected appearance of new lesions after initial improvement following treatment with antitubercular agents. Various types of paradoxical responses have been reported in the world, but they are rarely reported in Korean children. We report the case of a 17-year-old boy who was diagnosed with tuberculous pleurisy and was treated appropriately. Although the tuberculous pleurisy initially responded to medication with resolution of the pleural fluid, a new pulmonary lesion subsequently developed 3 weeks after the initiation of treatment that eventually cleared with continuation of the original drug regimen.

The objectives of the current work is to understand the factors impacting the formulation and performance of a Carbopol mucoadhesive buccal delvery system for a model peptide drug, $[D-Ala{^2},\;D-Leu{^5}]$enkephalin (DADLE, Mw=569.7) with comparable chemical and enzymatic stability. Specifically, in vitro buccal DADLE delivery from the cross-linked poly(acrylic acid) (PAA) hydrogel system was characterized. In addition, the influences of several penetration enhancers on the ex vivo buccal absorption of DADLE were also studied. In this study, the PAA hydrogels generally swell to 100% of their original weight in the phosphate pH 7.4 buffer. The water penetration into the PAA hydrogel occurred based on a zero-order kinetics for the first 60 min and steadily decreased afterwards. From the release study, it can be seen that the initial DADLE release was so rapid and the rate of release of DADLE decreased as the time elapsed. The porcine buccal tissue was found to be permeable to DADLE with a flux value of $0.07%/cm{^2}/hr({\pm}0.01\;SD)$. From the ex vivo diffusion study, it was found that sodium taurodihydrofusidate showed a greater degree of enhancement compared to the phospholipids with an Enhancement Ratio (ER) of 8.7 compared to 2.7 and 1.9 for didecanoylphosphatidylcholine and lysophosphatidylcholine, respectively. The work encompassed within this paper has demonstrated the feasibility of using the PAA hydrogel delivery system with its good mucoadhesive properties for the buccal delivery of peptides.

Korean ginseng(Panax Ginseng C.A. Meyer) known as a oriental miracle drug is an important medicinal plant. Ginseng has been used for geriatric, tonic, stomachic, and aphrodisiac treatments for thousands years. Also, it is an antibiotic and has therapeutic properties against stress and cancer. Ginseng is widely distributed all over the world. Among them, Korean mountain ginseng has the most valuable effect on pharmaceuticals. The roots of mountain ginseng contained several kinds of ginsenosides that have many active functions for the human body. However, the study of mountain ginseng has a limit because the mountain ginseng is very expensive and rare. So, we artificially cultured mountain ginseng adventitious roots using the bioreactor culture system. We induced callus from original mountain ginseng, directly dug up in mountain and aged about one hundred ten years. Separated adventitious roots were precultured in 500ml conical flasks and then, transferred in 20L bioreactors. The adventitious roots of mountain ginseng were harvested after culturing for 40days, dried and then, extracted with several solvents. In this study, we investigated the whitening effect, anti-wrinkle effect and the safety of tissue cultured adventitious roots extract of mountain ginseng in order to identify the merit as a cosmetic ingredient. Particularly, extract of mountain ginseng adventitious roots showed whitening and anti-wrinkle effects. The inhibitory effect of this extract on the melanogenesis was examined using B-16 melanoma cell. When B-16 melanoma cells were cultured with adventitious root extract, there was a dramatically decrease in melanin contents of 8-16 melanoma cell. And we identified this extract inhibited Dopa auto-oxidation significantly. Also, when transformed mouse fibroblast L929 cells were treated with this extract, there was a significant increase in collagen synthesis. The results show significant inhibited melanization and wrinkle without inhibiting cell viability.

Objectives: In homeopathy, it is claimed that more homeopathically-diluted potencies render more protective/curative effects against any disease condition. Potentized forms of Condurango are used successfully to treat digestive problems, as well as esophageal and stomach cancers. However, the comparative efficacies of Condurango 6C and 30C, one diluted below and one above Avogadro's limit (lacking original drug molecule), respectively, have not been critically analyzed for their cell-killing (apoptosis) efficacy against lung cancer cells in vitro, and signalling cascades have not been studied. Hence, the present study was undertaken. Methods: 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assays were conducted on H460-non-small-cell lung cancer (NSCLC) cells by using a succussed ethyl alcohol vehicle (placebo) as a control. Studies on cellular morphology, cell cycle regulation, generation of reactive oxygen species (ROS), changes in mitochondrial membrane potential (MMP), and DNA-damage were made, and expressions of related signaling markers were studied. The observations were done in a "blinded" manner. Results: Both Condurango 6C and 30C induced apoptosis via cell cycle arrest at subG0/G1 and altered expressions of certain apoptotic markers significantly in H460 cells. The drugs induced oxidative stress through ROS elevation and MMP depolarization at 18-24 hours. These events presumably activated a caspase-3-mediated signalling cascade, as evidenced by reverse transcriptase-polymerase chain reaction (RT-PCR), western blot and immunofluorescence studies at a late phase (48 hours) in which cells were pushed towards apoptosis. Conclusion: Condurango 30C had greater apoptotic effect than Condurango 6C as claimed in the homeopathic doctrine.

The modulation of cytochrome P450(P450) activities and glutathione S-transferase (GST) was investigated after i.p. administration of glucose-diethyldithiocarbamate (Glu-DDTC) to rats. P450 1 A2 and 2El activities were inhibited by 60% 4 hr after the administration of 200 mg Glu-DDTC/kg and those activities were recovered to original levels 24 hr after dosing. In contrast, GST activities were enhanced up to 24 hr after dosing. These results seem to be due to the bifunctional activity of Glu-DDTC. Glu-DDTC acts as an inhibitor of P450 enzymes as well as inducer of GST enzyme. Glu-DDTC inhibited PNP hydroxylation (P450 2El) and ethoxycoumarin O-deethylation (P450 1A2) in a dose-dependent manner up to 200 mg/kg wherease it did not affect testosterone 6$\beta$-hydroxylation (P450 3A) and pentoxyresorufin O-dealkylation (P450 2B) activities. Induction of GST activity toward 1-chloro-2,4-dinitrobenzene (CDNB) and 1,2-dichloro-4-nitrobenzenen (DCNB) was dependent on the dose of Glu-DDTC and no species difference in the GST induction was seen between rat and mouse. Amoung GST subunits, Ya, Yb1 and partially Yb2 were induced by Glu-DDTC as conjugated by western blotting. The levels Yp, Yk and Yc subunits were not affected by Glu-DDTC treatment. Therefore the enhanced activity of GST toward CDNB and DCNB might be due to the induction of Ya, Ybl and partially Yb2 subunits. In conclusion, Glu-DDTC selectively inhibited P45O 1A2 and P450 2El activities whereas it enhanced Ya, Ybl subunits and partially Yb2 subunits of GST and the antimutagenic activity of this compound might be attributed from the modulation of these enzyme activities in animals.

It's a threat for the public health that H1N1 (Influenza virus A) causes disease and transmits among humans. WHO (world health organization) declared that the infections caused by the new strain had reached pandemic proportions. The approved neuraminidase inhibitors (Zanamivir and Oseltamivir) and related investigative drug (BCX-1812) are potent, specific inhibitors of influenza A and B viruses. These drugs are highly effective to prevent influenza A and B infections. Early therapeutic use reduces illness duration and respiratory complications. Recently, we found one of the potent inhibitor of erystagallin A ($IC_{50}$ of 2.04 ${\mu}M$) for neuraminidase target, this inhibitor shows most similar structure to its natural substrate, sialic acid. Therefore, we chose 1l7f to get the receptor structure for docking study among many crystal structures. A docking study has been performed in Surflex-Dock module in SYBYL 8.1. In the present study, we attempt to compare the docking studies of pterocarpin and erystagallin A with neuraminidase receptor structure. In the previous report, the methoxy group of pterocarpin had H-bonding with Arg residues. The present docking results for erystagallin A showed the backbone of hydroxyl group shows significant H-bonding interactions with Arg152 and Arg292. The results showed that erystagallin A interacts more favorably with distinctive binding site rather than original active site. Therefore, we tried to reveal plausible binding mode and important amino acid for this inhibitor using docking and site id search calculations of Sybyl. The results obtained from this work may be utilized to design novel inhibitors for neuraminidase.

Objectives This research was proposed to present Clinical Practice Guideline (CPG) for Prevention of Sasangin disease pattern of Sasang Constitutional Medicine (SCM) and diseases closely related with Sasang constitution. Each CPG was developed by the national-wide experts committee consisting of SCM professors. Methods At first, we searched the literatures related to SCM such as "Dongeuisusebowon", Textbook of SCM and Clinical Guidebook of SCM. Also we searched the articles related to the studies about risk factors for Sasangin disease pattern of both at home and abroad. Finally, we selected leading risk factors of Sasangin disease pattern and developed CPG for prevention of Sasangin disease pattern of SCM. And then, we searched the literatures related SCM such as "Dongeuisusebowon" and the articles on the correlation between disease and Sasang constitution using case-control studies, observational studies or cross sectional studies of both at home and abroad. Next, we selected diseases closely related with Sasang constitution on the basis of articles including prevalence rate and odds ratio between disease and Sasang constitution and finally developed CPG for these diseases. Results and Conclusions We categorized risk factors of Sasang disease pattern into 2 types: non-modifiable and potentially modifiable. 3 items (age, sex and genetic factors) were classified as non-modifiable risk factors of Sasang disease pattern. 6 items (original symptom, stress, diet and nutrition, physical activity, alcohol and drug misuse) were classified as less well-documented or potentially modifiable risk factors of Sasangin disease pattern. We found out Sasang constitution is more likely to develop some diseases. It was proven that Sasang constitution increase the risk of hypertension, diabetes mellitus, metabolic syndrome, stroke, nonalcoholic fatty liver and obstructive sleep apnea. And there is high probability of Sasang constitution being potential risk factor for obesity, hyperlipidemia, allergy and cancer. Also, we found out Taeeumin is independent risk factor for hypertension, diabetes mellitus, metabolic syndrome, stroke, nonalcoholic fatty liver and obstructive sleep apnea. Therefore we recommend that Taeeumin need to prevent these disease by regular checkups and aggressive management.

Pasting gelatinization of acorn flours which were prepared with soaked nut and sediment at 7.8$^{\circ}C$ for 0, 1, 2, 3 and 4 days were investigated. The peak temperature of gelatinization of untreated acorn flour (0-0) by Rapid Visco Analyzer was 73.1$^{\circ}C$, respectively, but those of flours were decreased by soaking. Peak viscosity, setback and breakdown of acorn flours were increased by soaking. In addition, consistency was increased by soaking treatment. From the result of the pasting properties, gel formation ability of acorn flour was increased with increasing soaking days of acorn nut and soaking times of sediment. The gelatinization temperature examined by X-ray diffractometry was lowered with increasing of soaking days. The observation of microstructure through a scanning electron microscope revealed that gelatinized acorn flour showed loser their original shape and structure than that of with out soaking treatment (0-0). The degree of gelatinization under the fixed temperature increased with increasing soaking days. From these results, it might be concluded that the increase of soaking days and soaking times is the factor affecting the gelatinization of acorn flour.
