Objectives: Quercetin and curcuminoids are important bioactive compounds found in many herbs. Previously reported high performance liquid chromatography ultraviolet (HPLC-UV) methods for the detection of quercetin and curcuminoids have several disadvantages, including unsatisfactory separation times and lack of validation according the standard guidelines of the International Conference on Harmonisation of Technical Requirements for Registration of Pharmaceuticals for Human Use. Methods: A rapid, specific, reversed phase, HPLC-UV method with an isocratic elution of acetonitrile and 2% v/v acetic acid (40% : 60% v/v) (pH 2.6) at a flow rate of 1.3 mL/minutes, a column temperature of $35^{\circ}C$, and ultraviolet (UV) detection at 370 nm was developed. The method was validated and applied to the quantification of different types of market available Chinese medicine extracts, pills and tablets. Results: The method allowed simultaneous determination of quercetin, bisdemethoxycurcumin, demethoxycurcumin and curcumin in the concentration ranges of $0.00488-200{\mu}g/mL$, $0.625-320{\mu}g/mL$, $0.07813-320{\mu}g/mL$ and $0.03906-320{\mu}g/mL$, respectively. The limits of detection and quantification, respectively, were 0.00488 and $0.03906{\mu}g/mL$ for quercetin, 0.62500 and $2.50000{\mu}g/mL$ for bisdemethoxycurcumin, 0.07813 and $0.31250{\mu}g/mL$ for demethoxycurcumin, and 0.03906 and $0.07813{\mu}g/mL$ for curcumin. The percent relative intra day standard deviation (% RSD) values were $0.432-0.806{\mu}g/mL$, $0.576-0.723{\mu}g/mL$, $0.635-0.752{\mu}g/mL$ and $0.655-0.732{\mu}g/mL$ for quercetin, bisdemethoxycurcumin, demethoxycurcumin and curcumin, respectively, and those for intra day precision were $0.323-0.968{\mu}g/mL$, $0.805-0.854{\mu}g/mL$, $0.078-0.844{\mu}g/mL$ and $0.275-0.829{\mu}g/mL$, respectively. The intra day accuracies were 99.589%-100.821%, 98.588%-101.084%, 9.289%-100.88%, and 98.292%-101.022% for quercetin, bisdemethoxycurcumin, demethoxycurcumin and curcumin, respectively, and the inter day accuracy were 99.665%-103.06%, 97.669%-103.513%, 99.569%-103.617%, and 97.929%-103.606%, respectively. Conclusion: The method was found to be simple, accurate and precise and is recommended for routine quality control analysis of commercial Chinese medicine products containing the flour flavonoids as their principle components in the extracts.

The author investigated whether Chwiyeon-tang(PC), Haengso-tang(PH), Jawanchihyo-san(PJ) and Gamisocheongryong-tang(PS) significantly affect both PMA-induced mucin production and MUC5AC gene expression in airway epithelial cells and sulfur-dioxide-induced airway goblet cell hyperplasia and mucus hypersecretion animal model using rat. Possible cytotoxicity of each herbal medicine was assessed by measuring the survival and proliferation rate of NCI-H292 cells. Confluent NCI-H292 cells were pretreated for 30 min in the presence of PC, PH, PJ and PS, respectively, and treated with PMA(10 $ng/m{\ell}$), to assess the effect of each herbal medicine on PMA-induced mucin production by enzyme-linked immunosorbent assay(ELISA). Effects of each herbal medicine on PMA-induced MUC5AC gene expression from the same cells were investigated. Also, hypersecretion of airway mucus and goblet cell hyperplasia were induced by exposure of rats to $SO_2$ during 3 weeks. Effects of orally-administered PC, PH, PJ and PS during 1 week on intraepithelial mucosubstances and hyperplasia of goblet cells were examined using histological analysis after staining the epithelial tissue with PAS-alcian blue. (1) PC, PJ, PS and PH did not show significant effects on the survival and proliferation of NCI-H292 cells ; (2) PC, PJ and PS significantly decreased PMA-induced mucin production from NCI-H292 cells ; (3) PC, PJ and PS significantly inhibit the expression levels of PMA-induced MUC5AC gene in NCI-H292 cells ; (4) Among PC, PJ, PS and PH, only PS decreased $SO_2$-induced hyperplasia of airway goblet cells and intraepithelial mucosubstances. This result suggests that PC, PJ and PS can not only affect the production of mucin but also affect the expression of mucin gene and this can explain, at least in part, the traditional use of PC, PJ and PS for controlling airway diseases showing hypersecretion of mucus in oriental medicine.

The pharmacological effect of Korean-Chinese traditional herbal medicine, Hawangyeonhaedoktang (HT) on experimentally induced-triglyceride accumulation in cultured human hepatocyte HepG2 cells was studied. HePG2 cells were cultured in the Dulbecco's modified Eagle's (DME) medium without (Control medium) or with HT (0.5 mg/mL and 5.0 mg/mL) containing 1 mM oleate, 0.2% bovine serum albumin (BSA), and glucose 4.5 mg/mL for 6 and 24 hours in experiment I and 2 mM oleate, 0.5% BSA, and glucose 4.5 mg/mL for 6, 24 and in hours in Experiment II or 1 and 3 hours in Experiment III. Oleate ［$^{14}$ C］(0.5 $\mu$Ci/mL medium) added as a radioactive lipid precursor in the experiment I. In the experiment I, the intracellular triglyceride concentration was decreased remarkably during incubation for 6 and 24 hours, in a dose-dependent manner. At the same time, HT caused a decrease in the incorporation of ［$^{14}$ C］ oleate into intracellular triglyceride fraction and the secretion of triglyceride labeled with ［$^{14}$ C］ oleate into medium. In the experiment II and III compared to experiment I, the triglyceride accumulation in HepG2 cells was occurred, and HT prevented the accumulation of triglyceride during incubation for 24 and 48 hours. This result suggest that HT prevent the triglyceride accumulation in human hepatocytes by its inhibiting action on the intercellular triglyceride biosynthesis.

In the Far-Eastern traditional medicine, Oi[Energy] implies a wide range of meaning and is emphasized. There is nothing that is not related to this Qi, as seen in physiology, pathology, the relationship between human body and nature, the movements of intestines and gyeongnak[energy networks], the process of outbreak and change of illness, remedial laws, the features and effects of drugs, and so on. Accordingly, Nei Jing also says, 'every sickness arises from OL' The Qi has multi-meanings, and each of lots Of past physicians researched and analyzed it in different perspective, thus making the Qi-theories much richer. Still. there were not so many physicians who discussed the theme of Daqi. The denomination of Daqi is seen in Nei Jing and Jin Gui Yao Lue, and the physicians like Yu Chang in Ming dynasty and Zhang Xi Chun in Cheng dynasty, etc. applied and utilized Daqi by exploring its functional actions for human life and associating it with clinical practices. Yu Chang said that Daqi is Xiong Zong Yangqi[Positive Energy in Breast] governing every Qi, and that if this Qi is full, it spreads through body and protects the body from sickness, and vice versa. Summarizing his researches on the Daqi in Jin Gui Yao Lue and on the opinions of Yu Chang as well as his experiences, Chang Xi Chun maintained that the Qi accumulated in breast must be named Daqi, which constitutes the contents of Zongqi[Chief Energy] mentioned in Nei Jing. Once the Qi is vacant, breathing is not smooth, whole body is enervated, spirit becomes dim, thinking ability falls drastically. Furthermore, if the Qi is extremely vacant or more worsens, breathing stops. And he prescribed the medicines including Sheng Xian Tang as remedies against the symptom of Daqi XiaXian[Fall in Great Energy]. The recognitions of Daqi by Yu Chang and Zhang Xi Chun are consistent with each other. At any rate, their theories and prescriptions may be high in practical value in contemporary clinics.

Alzheimer's disease (AD) is a neurodegenerative disorder associated with progressive memory loss and neuronal cell death. Although numerous previous studies have been focused on disease progression or reverse pathological symptoms, therapeutic strategies for AD are limited. Alternatively, the identification of traditional herbal medicines or their active compounds has received much attention. The aims of the present study were to characterize the ameliorating effects of spinosin, a C-glucosylflavone isolated from Zizyphus jujuba var. spinosa, on memory impairment or the pathological changes induced through amyloid-${\beta}_{1-42}$ oligomer ($A{\beta}O$) in mice. Memory impairment was induced by intracerebroventricular injection of $A{\beta}O$ ($50{\mu}M$) and spinosin (5, 10, and 20 mg/kg) was administered for 7 days. In the behavioral tasks, the subchronic administration of spinosin (20 mg/kg, p.o.) significantly ameliorated $A{\beta}O$-induced cognitive impairment in the passive avoidance task or the Y-maze task. To identify the effects of spinosin on the pathological changes induced through $A{\beta}O$, immunohistochemistry and Western blot analyses were performed. Spinosin treatment also reduced the number of activated microglia and astrocytes observed after $A{\beta}O$ injection. In addition, spinosin rescued the $A{\beta}O$-induced decrease in choline acetyltransferase expression levels. These results suggest that spinosin ameliorated memory impairment induced through $A{\beta}O$, and these effects were regulated, in part, through neuroprotective activity via the anti-inflammatory effects of spinosin. Therefore, spinosin might be a useful agent against the amyloid ${\beta}$ protein-induced cognitive dysfunction observed in AD patients.

Objective: In the winter of 2002, severe acute respiratory syndrome(SARS) began to spread throughout the world. More than 5,000 cases were reported in China, including over 1,700 cases in Hong Kong Special Administrative Region(Hong Kong SAR). The total number of cases reported from Canada and Singapore was more than 200. The total number of SARS cases world-wide reached 8,437 with incidences in 29 counties. Mortality from SARS is estimated at $10{\sim}12%$. When the SARS outbreak occurred in China, the State Administration of Traditional Chinese Medicine of China immediately initiated clinical research projects on the use of integrated herbal medicine and Western medicine for treating SARS. and, in Hong Kong SAR, research on the use of herbal medicine for the prevention and treatment of SARS. Reports were released during convalescence. The objective of this study is to overview twelve clinical SARS reports of WHO on the treatment of SARS with herbal medicine and evaluate the efficacy and safety of treatment of SARS with herbal medicine, and further to share experiences and knowledge of the treatment of SARS. Methods: Twelve clinical reports about SARS from the WHO were selected, overviewed and evaluated for efficacy and safety of treatments of SARS. Results and Conclusion: Twelve clinical reports about SARS showed that the integrated treatment may have advantages, and the advantages are reflected in the following findings: Firstly, herbal medicine is not targeted only at a specific etiology or a certain pathological link, but also at the pathological status of the patients at that particular time. Therefore, comprehensive readjustment was made through various angles, targets and channels to restore the balance of the body. Secondly, there are advantages in the differentiation of the disease and the treatment. Based on the various symptoms, herbal medicine enables the physician to adopt the most suitable principle, provide individual treatment, and to administer medicine in accordance with the actual process and nature of the illness. Thirdly, there are advantages in the results of the treatment; herbal medicine can relieve symptoms, promote absorption of lung inflammation, improve the degree of blood oxygen saturation, regulate immunological functions, reduce the required dosage of glucocorticoid and other Western medicines, and reduce case fatality rate, in addition to lowering the cost of treatment.

Oriental medicine as a candidate for effective cancer treatment recently gain positive concerns in fields of therapeutic oncology. that is why some herbal medicines have been empirically safer in toxicity than anticancer drugs used in western medicine, and to show excellent therapeutic efficacy in human trial. Thus, these effects by clinically applied-herbs have not yet fully demonstrated in experimental tumor model. This study was initiated to evaluate the antitumor effect of Insambaekhaptang as candidate of antitumor-herbal agent against B16 melanoma metastasized into C57BL/6 mice lung. In experiment to test whether Insambaekhaptang can directly kill cancer cells in vitro or not, Insambaekhaptang showed direct killing action in concentration or higher against B16 melanoma cells using MTT assay, and showed lower IC50. Another experiment to know whether Insambaekhaptang can inhibit growth and metastasis of cancer cell or not, Insambaekhaptang significantly inhibited Solid tumor by intraperiperal injected-melanoma and lung metastasis induced by intravenous injected-melanoma in inbred C57BL/6 mice. When quantitative survival time increasing, we could obtain results that increased 113% in treated by Insambaekhaptang. These results show that Insambaekhaptang can inhibit growth of B16 melanoma cells through various biological mechanisms.
