  • 'BaegMi(白薇)' is one of the Chinese crude drugs used mainly as an antipyretic and diuretic. The botanical origin of the crude drug has never been studied pharmacognostically. To clarify the botanical origin of BaegMi, the morphological and anatomical characteristics of Cynanchum species growing in Korea were studied. As a result, BaegMi was proved to be the root of Cynanchum atratum and Cynanchum ascyrifolium.

  • An Chung Hwan(安中丸) is a Chinesε patent medicine, which has been used for various purposes in Korea. An Chung Hwan is composed of 15 kinds of powdered crude drugs and has been used for stomachic disorder, acute and chronic indigestion, dyspepsia, and diarrhea. For the identification of individual crude drugs in such powdery mixtures, microscopic method may advantageously be used as it requires only a small amount of specimens. In this study, it is demonstrated that the microscopic method is very effective for the identification of 15 crude drug ingredients in An Chung Hwan.

  • This study analyzed the contents of the research papers of Complementary Medicine concerning the inhalation drug for asthma published in Pubmed during lately 10 years. As a result, the following conclusion was drawn. 1. There were 5 papers concerning 2 review articles, 2 experimental studies and 1 clinical study. 2. Interventions of research papers are glutathione, microorganism fermentation extract (EM-X), ginkgolide and compound Chinese herbal monomer recipe (ligustrazin, baicalin, ginkgolide). 3. There is no controlled study for effect of inhaled glutathione, on the contrary it induced bronchial constriction in sulfites sensitive asthmatics. 4. Inhalation of EM-X reduced airway hyper-reactivity and level of IL-4, IL-5 and IL-13 in OVA challenged asthmatic mice. 5. Ginkgolide nebulized inhalation reduced symptomatic scorings and eosinophil cationic protein, improved FEV1 and PEF. 6. Compound Chinese herbal monomer (CHM) recipe reduced blood eosinophil count, eosinophil count and total cell cound in BALF, depressed airway hyper-responsiveness and airway inflammation.

  • The protective effect of Naoxingtong (NXT) on rat cerebral microvascular endothelial cell (rCMEC) was investigated. rCMEC was injured in vitro by incubating for 4 hours at 100% NO in a hypoxia chamber. After treated with NXT-containing serum, the cellular viability rate (90.3%) was significantly elevated when compared with that of control group and the inhibitive rate of lactic dehydrogenase activity (9.2%) was far lower than the control group with dose-dependent effect. The results indicate that NXT can increase viability of rCMEC, and protect cell membrane from injury during hypoxia.

  • Effects of Naoxintong (NXT, a formula of Chinese Materia Medica)-containing serum on Nitrogen monoxide (NO) and calcitonin gene related peptide (CGRP) in rat cerebral microvascular endothelial cells (rCMEC) was investigated, rCMEC was injured in vitro by incubating for 4 hours at 100% NO in a hypoxia chamber. The results indicated that NXT could antagonize the reduction of NO and CGRP secreted by rCMEC during hypoxia, the effect of which was dose-dependent. After treated with NXT-containing serum at dosage of 5.0 - 30 and 50 -1.1 g/kg/U respectively, the amount of NO and CGRP secreted by rCMEC were remarkably increased during hypoxia in vitro.

  • Objectives : To discuss the types of control groups in randomized controlled trials (RCTs) of herbal medicine, and to provide suggestions for improving the design of control group in future clinical trials. Methods : We reviewed the 8 articles about clinical trial design of Chinese herbal preparation which were published from 2005 through 2008. We selected those articles from CNKI(中國知識基礎施設工程(http://www.cnki.net)). Results : It is necessary to have control group in randomized controlled trials(RCTs) of Korean herbal preparation. But there are problems in the selection of appropriate control group drug. This paper lists several problems about the choice of control drug and puts forward some proposals and countermeasures. There are problems such as ethics and manufacturing matching placebo and positive control herbal drug. Conclusion : To improve the quality of control group design, we introduce standard drug plus placebo drug method and add-on research for placebo control group design, double dummy technique, using negative control drug or composite control drug for active control group design.

  • Curcumol is a sesquiterpene originally isolated from curcuma rhizomes, a component of herbal remedies commonly used in oriental medicine. Its beneficial pharmacological activities have attract significant interest recently. In this study, anti-cancer activity of curcumol was examined with both in vitro and in vivo models. It was found that curcumol exhibited time- and concentration-dependent anti-proliferative effects in SPC-A-1 human lung adenocarcinoma cells with cell cycle arrest in the G0/G1 phase while apoptosis-induction was also confirmed with flow cytometry and morphological analyses. Interestingly, curcumol did not display growth inhibition in MRC-5 human embryonic lung fibroblasts, suggesting the anti-proliferative effects of curcumol were specific to cancer cells. Anti-neoplastic effects of curcumol were also confirmed in tumor bearing mice. Curcumol (60 mg/ kg daily) significantly reduced tumor size without causing notable toxicity. In conclusion, curcumol appears a favorable anti-cancer candidate for further development.

  • Amino-acid neurotransmitter system dysfunction plays a major role in the pathophysiology of depression. Several studies have demonstrated the potential of amino acids as a source of neuro-specific biomarkers could be used in future diagnosis of depression. Only partial amino acids such as glycine and asparagine were determined from certain parts of rats' brain included hippocampi and cerebral cortex in previous studies. However, according to systematic biology, amino acids in different area of brain are interacted and interrelated. Hence, the determination of 34 amino acids through entire rats' brain was conducted in this study in order to demonstrate more possibilities for biomarkers of depression by discovering other potential amino acids in more areas of rats' brain. As a result, 4 amino acids (L-aspartic acid, L-glutamine, taurine and ${\gamma}$-amino-n-butyric acid) among 34 were typically identified as potentially primary biomarkers of depression by data statistics. Meanwhile, an antidepressant called Fluoxetine was employed to verify other potential amino acids which were not identified by data statistics. Eventually, we found L-${\alpha}$-amino-adipic acid could also become a new potentially secondary biomarker of depression after drug validation. In conclusion, we suggested that L-aspartic acid, L-glutamine, taurine, ${\gamma}$-amino-n-butyric acid and L-${\alpha}$-amino-adipic acid might become potential biomarkers for future diagnosis of depression and development of antidepressant.

  • 농산부산물첨가배지 개발로서 이화학적 특성은 콩비지첨가구에서 유기물, 질소, 탄소 함량이 높았으며 전처리구의 pH, 유기물, 질소, 탄소 함량은 버섯 생육시 적합한 것으로 판단되었다. 애느타리 관행재배시 병당(850cc)에서 갓의수 20개 72g에 비하여 콩비지 10% 첨가구는 갓의 수 12개 수량 77g으로 7% 증수, 귤껍질 10% 첨가구는 갓의 수 21개 수량 11% 증수되었다. 버들송이 관행재배시 병당 (850cc) 수량 98g 대비 한약박을 제외한 모든 농산부산물 첨가해서 증수되었으나 그중 콩비지 10% 첨가구가 수량 113g으로 15% 증수되었다. 저비용 고효율 농산부산물 버섯 배지개발로써 농가경영비 절감과 고품질 버섯 생산으로 농가소득에 기여할 것이다.

  • Chrysin (5,7-dihydroxyflavone) is a flavonoid compound contained in many fruits, vegetables and honey. In our experiment, we investigated genotoxicity of chrysin using bacterial reverse mutation assay, chromosomal aberration test, in vivo micronucleus test. In bacterial reverse mutation assay, chrysin did not induce mutagenicity in Salmonella typhimurium TA98, TA100, TA1535, TA1537, TA102 with and without metabolic activation. In chromosome aberration test, chrysin did not also induce structural and numerical abberations regardless of metabolic activation in Chinese hamster lung fibroblast cells. In mouse micronucleus test, no significant increase in the occurrence of micronucleated polychromatic erythrocytes (MNPCE) was observed in ICR male mice orally administered with chrysin at the dose of 0.5, 1.0, 2.0 g/kg body weight. Taken together these results, chrysin has no mutagenic potential in our experiment.
