Sophorae Flos (SF), a composite of flowers and flower-buds of Sophora japonica, has long been used in traditional Korean and Chinese medicines for the treatment of hemostasis and inflammation. In this study, we investigated anti-inflammatory effect of four EtOH extracts at the difference in blooming stages of flowers on LPS-induced inflammation in RAW264.7 cells. We classified the flowers of Sophora japonica with SF-1 (length of flower is shorter than calyx), SF-2 (length of calyx is shorter than flower), SF-3 (full bloom), and SF-4 (not blooming at all). We examined HPLC analysis, whether quercetin and rutin are major component of these Sophorae Flos extracts or not. As a result, SF-1 contained quercetin, but the others did not. In addition, quercetin, SF-1, and SF-4 act on the suppression of pro-inflammatory mediators including inducible nitric oxide synthase (iNOS), cyclooxygenase (COX)-2, nitric oxide (NO), prostaglandin E2 ($PGE_2$) against lipopolysaccharide (LPS)-induced activation in RAW264.7 cells. Of these, SF-1 showed the best anti-inflammatory effect. These results suggest that Sophorae Flos with the highest content of quercetin would be used for the treatment of various inflammation diseases.

In terms of regulatory toxicology, especially for the traditional Chinese medicines, problems can be arise from a fact that there is no distinctive barrier between herbal drugs and food/beverage. An example is that many kinds of Chinese herbal materials have been also used as tea materials in Korea, China, Japan and Vietnam. Sixteen tea materials (also used as herbal materials) were extracted with 70% ethanol and the extract further partitioned with chloroform and water. Those ethanol extract and fractions were subjected to the SOS-Chromotest to examine potential mutagenicity. It was found that ethanol extract of Chaenomelis Fructus (Chaenomeles japonica Lindley, 木瓜, Rosaceae) and both ethanol extract and water fraction of Cassiae Semen (Cassia tora Linne, 決明子, Leguminosae) showed relatively high mutagenic activities in SOS-Chromotest.

Carcinous pain is severe and continuous so difficult to alleviate. Western drugs give rise to reaction such as anorexia, constipation, vomiting, general weakness and dyspnea, And they cause tolerence. External treatment is a way to put a patch or rub a liquid on the skin. The patch and liquid are made from herb medicine. In china, they have a good effect of alleviating carcinous pain to make use of external treatment. Usually they use the medicine with effect of reprecussion (消腫), removing obstruction(散結), activating blood flow and removing blood stasis (活血化瘀) such like Borneloum(?片). Bufonis Venenum (蟾?), Aconiti ciliane Tubber(草烏), Arisaematis Rhizoma(南星), Asari herba cum Radice (細辛) etc. We can get the alleviating effect more quickly and prevent reaction through external treatment.

Objectives: There is an increasing number of complex diseases that are progressively more difficult to be controlled using the conventional "single compound, single target" approach as demonstrated in our current modern drug development. TCM might be the new cornerstone of treatment alternative when the current treatment option is no longer as effective or that we have exhausted it as an option. Orthogonal stimulus-response compatibility group study is one of the most frequently employed formulas to produce optimal herbal combination for treatment of multi-syndromic diseases. This approach could solve the relatively low efficacy single drug therapy usage and chronic adverse effects caused by long terms administration of drugs that has been reported in the field of pharmacology and medicine Methods: The present review was based on the Science Direct database search for those related to the TCM and the development of antihypertensive TCM herbal combination using orthogonal stimulus-response compatibility group studies approach. Results: Recent studies have demonstrated that the orthogonal stimulus-response compatibility group study approach was most frequently used to formulate TCM herbal combination based on the TCM principles upon the selection of herbs, and the resulting formulated TCM formula exhibited desired outcomes in treating one of global concerned complex multi-syndromic diseases, the hypertension. These promising therapeutic effects were claimed to have been attributed by the holistic signaling mechanism pathways employed by the crude combination of herbs. Conclusion: The present review could serve as a guide and prove the feasibility of TCM principles to be used for future pharmacological drug research development.

Objectives The network pharmacological study on herbal remedies in Traditional Chinese Medicine (TCM) is actively being carried out based on the TCM databases such as TCMID and TCMSP. It is necessary to select Sasang Constitution-specific (SC-s) herbs from these databases in order to study the prescriptions in Sasang Constitutional Medicine. Methods SC-s herbs and their processing types listed in "Dongyisusebowon Sinchukbon" were searched from TCMID and TCMSP. Results and Conclusions 1. There were total 144 herbs (Soeum 47, Soyang 37, Taeeum 44, Taeyang 16 specific herbs) listed in "Dongyisusebowon Sinchukbon". 2. There were total 130 herbs (Soeum 43, Soyang 37, Taeeum 42, Taeyang 8 specific herbs) searched from TCMID, and total 92 herbs (Soeum 31, Soyang 30, Taeeum 27, Taeyang 4 specific herbs) from TCMID. 3. In some cases, the name given in "Dongyisusebowon Sinchukbon" was different from that in TCMID and TCMSP. It was needed to be careful during the searching process. 4. Although the processing form of some herbs could be searched, there was a significant reduction in the herbal compound information compared to the raw form. It is necessary to reconsider whether or not to use the processing form. 5. Herbal scientific names given in TCMID and TCMSP or used in China and Korea were different each other in some cases. Additional screening process among such herbs would be required based on the efficacy of herbs used in clinical field.

Objective : Arsenic trioxide ($As_2O_3$) has been used as an anticancer agent in traditional Chinese medicine for thousand years and berberine is an isoquinoline alkaloid present that has indicated significant antimicrobial activity. We have examined the combined anticancer effects of $As_2O_3$ and berberine against the human neuroblastoma (HNB) SH-SY5Y cells in vitro, and to elucidate underlying molecular mechanism. Methods : HNB SH-SY5Y cells were treated with $2\;{\mu}M\;As_2O_3$ and $75\;{\mu}g/ml$ berberine, and their survival, cell death mechanism as well as synergistic cytotoxic effects were estimated by using MTT assay, DAPI staining, agarose gel electrophoresis, flow cytometric analysis, and western blot analysis. Results : The combined treatment of two drugs also markedly decreased cell viability. The cytotoxic effects of two drugs were revealed as apoptosis characterized by chromatin condensation, DNA fragmentation, and the loss of mitochondrial membrane potential. The apoptotic cytotoxicity was accompanied by activation of caspase-3 protease as well as decreased the expression of Bcl-2, Bid, and Bcl-x/L. In addition, the cells treated with combination of two drugs also showed significantly increased intracellular reactive oxygen species levels and lipid peroxidation compared to cells $As_2O_3$or berberine only. Conclusion : Combined treatment of $As_2O_3$ with berberine induced activation of apoptotic signaling pathways in HNB SH-SY5Y cells. These results suggest that the possibility of the combined treatment of two chemotherapeutic agents with low concentration improving cytotoxic effect for cancer cells with minimal side effects.

Seventeen compounds derived from traditional Chinese medicines (TCMs) were tested for their antiviral activity against porcine reproductive and respiratory syndrome virus (PRRSV) in vitro. Visualization with the cytopathologic effect (CPE) assay and the 3-(4, 5-dimethyithiazol-2-yl)-2,5-diphenyltetrazolium bromide test were used to determine the 50% cytotoxic concentration ($CC_{50}$) and 50% effective concentration ($EC_{50}$) in cultured Marc-145 cells. Among the tested compounds, chlorogenic acid and scutellarin showed potential anti-PRRSV activity. The $EC_{50}$ values were $270.8{\pm}14.6{\mu}g/ml$ and $28.21{\pm}26.0{\mu}g/ml$ and the selectivity indexes were >5.54 and 35.5, respectively. The time-of-addition and virucidal assay indicated that the anti-PRRSV activity of the two compounds could be due to their inhibiting the early stage of virus replication and/or inactivating the virus directly. The inhibition of the virus attachment was not observed in the adsorption inhibition assay. The inhibition ratios of chlorogenic acid and scutellarin were, respectively, 90.8% and 61.1% at the maximum non-cytotoxic concentrations. The results have provided a basis for further exploration of their antiviral properties and mechanisms in vivo. We believe that the chlorogenic acid and scutellarin have a great potential to be developed as new anti-PRRSV drugs for clinical application.

Toxoplasma gondiiis a widespread apicomplexan parasite which is able to infect virtually all warm-blooded vertebrates. Twenty-two percent of the U.S. population is infected, but severe disease in adults is mainly limited to immunosuppressed patients. In patients with acquired immunodeficiency syndrome(AIDS), T. gondii causes a life-threatening opportunistic infection, with Toxoplasma encephalitis as its most severe manifestations. T. gondii is also known to cause congenital infection and is among the pathogens with the highest incidence of complications in pregnancies. Despite its clinical importance, only very few therapeutic drugs against T. gondii are available, all of which target the rapidly dividing tachyzoites, leaving the dormant encysted bradyzoite stage unaffected. We searched 15 traditional medicines that have anti-inflammatory effect from dongyibogam and Traditional Chinese medicine. In vitro studies were performed with HeLa cell cultures, with quantification of Toxoplasma growth by a cell proliferation assay. The result of experiment shows the selectivity of Citrus unshiu Markovich is 6.0. This is higher than sulfadiazine (selectivity was 1.63). For in vivo studies, mice were acutely infected intraperitoneally with $10^5$ tachyzoites of the virulent RH strain and then treated per orally for 4 days from 6 hours postinfection. Efficacy was assessed by sequential determination of parasite burdens in peritoneal cavity. In vivo, Citrus unshiu Markoviche inhibited Toxoplasma growth at a concentration of 10㎎/㎏ of body weight per day, the inhibition ratio was estimated to be 64.01%.
