왜당귀[Angelica acutiloba (Siebold & Zucc.) Kitagawa]를 대상으로 종자 발아 및 유묘 생육, 유용성분 함량과 관련된 GA₃ 처리 효과를 분석하여 왜당귀 재배시 기초자료를 제공하고자 하였다. 왜당귀 종자의 수분흡수율은 침지 2시간이 경과한 시점에서 62.07%를 나타냈고, 48시간이 경과한 시점에서 122.15%로 가장 높은 값을 나타냈다. 왜당귀 종자의 적정 발아온도는 10℃에서 25℃로 확인되었으며, 5℃에서는 발아가 진행되지 않았고, 30℃에서는 GA₃ 농도가 증가함에 따라 발아율이 유의하게 증가하였다. 또한 유묘 생육은 GA₃ 처리농도가 높아질수록 양호하였으나 유용성분 함량의 경우 실험구에 따른 유의성이 확인되지 않았다. 이러한 결과는 약용 및 식용으로 활용성이 높은 왜당귀에 대한 최적 재배와 생산기술 정립에 기초자료로 활용할 수 있을 것으로 판단된다.

In recent years, several therapeutic drugs have been rationally designed and synthesized based on the novel knowledge gained from investigating the actions of biologically active chemicals derived from foods, plants, and medicinal herbs. One of the major advantages of these naturalistic chemicals is their ability to interact with multiple targets in the body resulting in a combined beneficial effect. Ginseng is a perennial herb (Araliaceae family), a species within the genus Panax, and a highly valued and popular medicinal plant. Evidence for the medicinal and health benefits of Panax ginseng and its components in preventing neurodegeneration has increased significantly in the past decade. The beneficial effects of P. ginseng on neurodegenerative diseases have been attributed primarily to the antioxidative and immunomodulatory activities of its ginsenoside components. Mechanistic studies on the neuroprotective effects of ginsenosides revealed that they act not only as antioxidants but also as modulators of intracellular neuronal signaling and metabolism, cell survival/death genes, and mitochondrial function. The goal of the present paper is to provide a brief review of recent knowledge and developments concerning the beneficial effects as well as the mechanism of action of P. ginseng and its components in the treatment and prevention of neurodegenerative diseases.

Liu Hejian maintained that the six types of energy can become fire and focused on the treatment of fire and heat symptoms along with the prescriptions of cryotherapy, believing that a vast majority of disease are due to fire. In this study, we investigated the characteristics of Hejian's formulae by classifying medicinal ingredients in consideration of medicinal properties and efficacy in order to examine how many cold and hot medicinal ingredients are included in the formulae of Hejian. We analysis 848 formulae among 1,055 formulae in total, excluding 207 redundant ones, which includes 366 Sunmyunglon formulae, 223 Bomyeongjip formulae, 8 Samsolon formulae, 61 Sanghanjigkyeok formulae, 68 Sanghanpyobon formulae, 22 Sanghansimyo formulae, 103 Hwalbeopgiyo formulae, 186 Bodongbiyo formulae, and 18 Gagamyoungbisippalbang formulae. In the analysis of the frequency of using each medicinal herb after classifying medicinal ingredients of Hejian's formulae by medicinal properties, we found that cold medicinal ingredients accounted for 40%, the biggest share in the formulae, and hot medicinal ingredients accounted for around 45%, which indicates that Hejian's formulae consist of both elimination and reinforcement and cold and heat, rather than cold medicinal ingredients only. As a comparison of the frequency of using each medicinal ingredients for the formulae by efficacy, we found that clear heat medicinal ingredients, totify qi and replenish blood medicinal herbs, and activate blood medicinal ingredients were most frequently used.

Objectives: Hypertrophic scars (HSs) are caused by abnormal wound healing. To date, no standard treatment has been made available for HSs. Scrophularia striata has been reported to accelerate wound healing and has the potential to prevent HS formation. In this study, we investigated the anti-scarring effects of S. striata extract (SSE) in a rabbit ear model of scarring. Methods: In this study, New Zealand white rabbit (weight: 2.3-2.5 kg) were used. In the prevention phase of the study, three test groups received 5%, 10%, and 15% ointments of SSE in the Eucerin base, the fourth group received Eucerin, and the fifth group received no treatment. The samples were obtained on day 35 after wounding. In the treatment phase of the study, the test groups received an intralesional injection of SSE (5%, 10%, and 15%), the fourth group received an intralesional injection of triamcinolone, the fifth group received a solvent (injection vehicle), and the sixth group received no treatment. To evaluate the anti-scarring effects of SSE, the scar elevation index (SEI), epidermis thickness index (ETI), collagen deposition, and MMP2 and MMP9 gene expression were evaluated. Results: A significant reduction in SEI, ETI, and collagen deposition was noted in animals treated with SSE compared with the control groups. In addition, topical SSE stimulated MMP2 and MMP9 gene expression. Conclusion: The findings of this study demonstrate the potential for SSE in the prevention and treatment of HS. SSE could be prepared as an appropriate formulation to treat wounds and prevent abnormal scarring.

DNA damage induced by reactive oxygen species (ROS) seems to play an important role in the induction of mutation and cancer. Hydrogen peroxide $(H_2O_2)$ has been shown to induce a variety of genetic alterations, probably by the generation of hydroxyl radicals via Fenton reaction. In this study, we examined the ability of medicinal herbs in the suppression of $H_2O_2$-induced mutagenesis. Human fibroblast GM00637 cells were treated with $H_2O_2$ in the presence or absence of medicinal herbs, and $H_2O_2$-induced mutant frequency was measured at the hypoxanthine guanine phosphoribosyl transferase (HPRT) locus. Treatment of cells with various doses of $H_2O_2$ caused a significant increase of the HPRT mutant frequency. However, pretreatment of cells with several medicinal herbs reduced $H_2O_2$-induced mutant frequency. The strong antimutagenic effects were observed from the methylene chloride and ethyl acetate fractions of Selaginella tamariscina, Panax ginseng, and Angelica acutiloba; ethyl acetate fractions of Rehmania glutinosa, Leonurus sibiricus, Curcuma zedoaria and Commiphora molmol; butanol fractions of Scutellaria barbata, Tribulus terrestris, Curcuma zedoaria, Cyperus rotundus and Carthamus tinctorius, which were more than 60% inhibition of $H_2O_2$-induced mutant frequency at the HPRT locus.

Background : This study was carried out to investigate the changes to fatty acid, mineral, and ginsenosides contents in ginseng seed when they were stratified for different length of time and to determine whether variety had any effects on the changes. The aim was to improve the ginseng seed stratification process. Methods and Results : The ginseng varieties used were Geumpoong, Chunpoong, Yunpoong, and K-1. Stratifying periods treated on ginseng seed were 0, 20, 40, 60, 80, and 100 days. The main fatty acids of ginseng seed were oleic acid (C18 : 1, n9c) with a content of 78.40 - 79.20% followed by linoleic acid (C18 : 2, n6c). The main mineral in the seeds was potassium (K), at 1208.2 -1337.6 mg/100 g. The main ginsenosides in ginseng seed were ginsenoside Re and Rb1. Increasing the length of the stratification periods led to increases in oleic acid content (60 - 80 days), however after this the content declined. In contrast, linoleic acid content fell as the stratification period increased. K, P, Mg, Ca and Na content rose as the stratification period increased. The ginsenoside Re content of Chunpoong and K-1 cultivar seeds also rose as the stratification period increased which meant that total ginsenoside content increased. However, ginsenoside Re content rose in Geumpoong and Yunpoong seeds, but total ginsenoside content decreased as the stratification period increased. Conclusions : Some beneficial compound in ginseng seed rose as the stratification period increased. Therefore, ginseng seed stratification could improve the food value of ginseng.

Background: Lung cancer, the most common malignant disease worldwide, is the predominant cause of cancer deaths, particularly amongst men. Therefore, various researchers have focused on the growth inhibitory effects of medicinal plants used in traditional Korean medicine. This study aimed to investigate the growth inhibitory effects of ethanol extracts of Rubiae radix, Inulae flos, Nelumbinis receptaculum, Astilbe radix, and Lagerstroemia flos on NCI-H1229 cells. Method and Results: The viability of NCI-H1229 cells was evaluated in vitro using an MTS assay. Treatment with the ethanol extracts of the selected medicinal plants at $500{\mu}g/m{\ell}$ reduced NCI-H1229 cell viability and increased apoptotic cell death and caspase-3 activation. In addition, treatment with ethanol extracts of Inulae flos and Astilbe radix increases DNA fragmentation, as measured by the TUNEL assay. Conclusions: These results indicated that ethanol extracts of Rubiae radix, Inulae flos, Nelumbinis receptaculum, Astilbe radix, and Lagerstroemia flos exhibited growth inhibitory effects, inducing apoptotic cell death, DNA fragmentation and caspase-3 activation in NCI-H1229 cells. Therefore, these medicinal plant extracts may be used in the development of natural medicines to inhibit the growth of lung cancers. However, further study is needed to determine the active ingredients of the ethanol extracts from medicinal plants that are reposible for the inhibitory effect on lung cancer cell grwoth.

In children, flesh and muscle are tender, mental function is feeble, digestion and absorption are weak. Also food, drink and medicine which burden the stomach and bowels must be avoided. Oriental medicines are divided in object of medical treatment into three types, liquid medicine, medicinal powder and pill. In spite of this types, time and effort are spended greatly on children's eating medicine. In this paper, studying general characteristic of oriental medicinal types and effective types of oriental medicine, I can obstain such conclusions. 1. The oriental iense pillow remedy sets at easy, promotes degistion, treats disease of theesporatory organs. 2. The distillation remedy is suited to a chronic disease of children the degistion are ak in. 3. The mother remedy, because medicine is supplied through mother's body, is effective to infant. 4. The external use remedy is suited to skin disease, eye disease and nose disease, and has similar effect to taking liquid medicine. 5. The confectionery remedy is the method which children like greatly, but is the effective method to many children because of technical manufacture.
