The objectives of this study were to develop porridge with medicinal herbs and chicken breast meat and to find out the optimum mixing ratio. Several herb extracts such as Acanthopanacis senticosus, Rehmannia glutinosa, Disocorea japonica, and Poria cocos Wolf were used in the ratio of 2, 1, 1, and 1, respectively. The optimum processing condition for herbal chicken porridge was determined by a design expert program. Seventeen experimental points were selected, and herb extracts (82~101 g), chicken breast meat (30~50 g), and glutinous rice (40~60 g) were chosen as the independent variables. The measured responses were preference of taste, DPPH radical scavenging, SOD-like activity, and cost. The optimum formulation of herbal chicken porridge using the numerical analysis was set at herbal extracts (101 g), chicken breast meat (38.66 g), and glutinous rice (41.34 g) with a 0.714 desirability value. DPPH radical scavenging effect, preference of taste and the cost showed a linear model, whereas SOD-like activity showed a quadratic model indicating a higher interaction among the mixture. As a result of proximate composition of optimized herbal chicken porridge, the contents of moisture, carbohydrate, crude protein, crude lipid, and ash contents were 76.4, 9.0, 1.4, 0.5, and 1.6%, the calories of the porridge was 46.1 kcal/100 g.

The purpose of this study was to investigate how microwave drying, a method to minimize the scent and physicochemical changes of the final products, affects the quality characteristics of various herbs according to treatment intensity (pulse and continuous waves) and time. In the current study, different physicochemical qualities, such as weight change, moisture content, water activity, color, and microbial growth, of five different Korean herbs were analyzed after microwave drying. The results clearly showed that the pulse wave method was a more effective approach than the continuous wave method for maintaining the physicochemical properties of herbs. Furthermore, pulse wave drying lead to efficient microbial death in various herbs after a short time. Thus, microwave drying with a pulse wave can be applied to herb processing and packaging technology while minimizing the quality changes of herbs.

Objectives : In Pharmaceutical Affairs Act, herbal medicinal preparations are defined as medicines made by Korean medicine principles. But in Act, Korean medicine principles are vague. Thus, there is a request to explain what the Korean medicine principles are. The aim of this study is to suggest implications of Korean medicine principles in definition of herbal medicinal preparations. Methods : With regard for definition of Korean medicine principles, we referred to the domestic and foreign regulations and literature about the history of herbal medicinal preparations. As a result, the meaning of Korean medicine principles was historically examined from various angles. Results : Through this study, we studied the Korean medicine principles from the past medical history. Due to the broad definition of Korean medicinal principles, we tried to extract general ideas of medicine principles first. We also found that we had scientific formulations based on korean medicine principles which could be used in modern society. In the end, we found that numerous medicine principles which include ‘Four qi and five flavors theory’, ‘Processing of medicinals’, ‘Yin and yang theory’, ‘Five phases theory’, ‘Meridian entry of viscera and bowels theory’, ‘Herb Couplet Interaction theory’, ‘Sovereign, minister, assistant and courier theory’, etc. Conclusions : Innumerable principles used from the past existed. These principles were broad and could be used as modern scientific principles. Based on these facts, we illustrated details of Korean medicine principles, hope this principles be widely shared and Korean herbal medicinal preparations be further developed.

Objectives : In the WIPO conference about the protection of intellectual property for traditional knowledge (TK) and genetic resources (GR), there was a demand concerning the necessity of recognizing the invention of TK and GR and the foundation of a related database. Methods : In the standard of the foundation of a database, the content and resource identification standards, the technological standards and the security and transmission standards were discussed. In a decision on intellectual property, it means the protection and recognition as a technology precedent of the materials of the database. Results : Massive material on traditional medical care technology in Korea has existed in many areas. However, it is hard to make a database because it is difficult to organize and find the data. In addition, a database demanded by WIPO is not only the material of images or texts of simple technology information, but also the use of patent decisions about traditional knowledge technology and the public sharing of information in related areas. A traditional medical care database would consist of the core of a subject and the related areas. The core part is the medical herb resource and Oriental clinical technology. Conclusions : These are necessary to detail the kind of medicines and prescriptions, their use, and their processing. In the related areas, it needs to detail PIAS and clinical data in regarding the industrialization. These DB have to protect the TK and the GR of Korea.

Iris odaesanensis Y. N. Lee. is an important endangered and native plant belonging to the family Iridaceae in Korea. This study describes a method for rapid micropropagation of this species via from leaf, rhizome and root explants derived calli. Leaf, rhizome and root explants were cultured on Murashige and Skoog (MS) medium supplemented with 2,4-dichlorophenoxy acetic acid (2,4-D) for callus induction. Rhizome explants yielded calli at a frequency of 72% when cultured at 1.0 mg/l 2,4-D. Calli were maintained at 1.0 mg/l 2,4-D. These calli were transferred to MS medium supplemented with 0, 0.5, 1.0, and 2.0 mg/l 2,4-D in combination with 0, 0.5, 1.0, and 3.0 mg/l BA for adventitious shoot induction. The highest number of adventitious shoot (228.9 per petri-dish) were formed at 1.0 mg/l 2,4-D and 1.0 mg/l BA. WPM medium was the best to convert calli into plantlets, where up to 98.2% of calli were regenerated into plantlets. This in vitro propagation protocol should be useful for conservation of this endangered plant.

Angelica gigas Nakai (danggui) is a popular herb which has been used as a blood-building decoction for recovery from weakness in the Chinese medicine. Its demand increased in functional foods and pharmaceutical industries. For its hygiene, fumigation has been used, but the use of fumigants are going to be prohibited for food processing. In order to investigate gamma irradiation technique for hygiene of danggui, the immunomodulation activity of danggui after irradiation was examined. The water extract of irradiated danggui showed a strong mitogenic effect on splenocytes in vitro to the same level of lipopolysaccharide (LPS) and phytohemagglutinin (PHA). The effect was not different from that of non-danggui. It was tested whether there was any difference between irradiated and non-irradiated danggui in effects on the secretion of antibodies and graft versus host reaction in vivo. It turned out that intraperitoneal (i.p.) administration of the extract of irradiated danggui for 4 days remarkably increased the number of antibody-secreting cells in mice injected with sheep red blood cells (SRBC). Splenomegaly, due to graft versus host reacton, was also increased after 7 days i.p. administration of the extract of danggui in mice injected with allogeneic splenocytes. In these two in vivo test, the effect were not different from those of non-irradiated danggui. These results indicated that immunomodulation activity of danggui might be preserved after irradiation. In the other experiments (data not shown), the irradiated danggui was stable in active component analysis and safe in genetic toxicity test. In further research, the stability in other physiological activity of irradiated danggui will have to be proved before practical application of irradiation for hygiene.

Background: Panax ginseng is one of the most commonly used medicinal herbs worldwide for a variety of therapeutic properties including neurocognitive effects. Ginsenoside Rg1 is one of the most abundant active chemical constituents of this herb with known neuroprotective, anxiolytic, and cognition improving effects. Methods: We investigated the effects of Rg1 on the medial prefrontal cortex (mPFC), a key brain region involved in cognition, information processing, working memory, and decision making. In this study, the effects of systemic administration of Rg1 (1 mg/kg, 3 mg/kg, or 10 mg/kg) on (1) spontaneous firing of the medial prefrontal cortical neurons and (2) long-term potentiation (LTP) in the hippocampal-medial prefrontal cortical (HP-mPFC) pathway were investigated in male Sprague-Dawley rats. Results: The spontaneous neuronal activity of approximately 50% the recorded pyramidal cells in the mPFC was suppressed by Rg1. In addition, Rg1 attenuated LTP in the HP-mPFC pathway. These effects were not dose-dependent. Conclusion: This report suggests that acute treatment of Rg1 impairs LTP in the HP-mPFC pathway, perhaps by suppressing the firing of a subset of mPFC neurons that may contribute to the neurocognitive effects of Rg1.

Background: Korean ginseng is a well-known medicinal herb that has been widely used in traditional medicine to treat various diseases, including asthma. Ginseng can be classified as white ginseng (WG) or red ginseng (RG), according to processing conditions. In this study, the authors compared the efficacies of these two ginseng types in a mouse model of acute asthma. Methods: To produce the acute asthma model, BALB/c mice were sensitized with ovalbumin (OVA) and aluminum hydroxide, and then challenged with OVA. WG and RG extracts were administered to mice orally. The influences of WG and RG on airway hyperresponsiveness (AHR), immune cell distributions in bronchoalveolar lavage fluid (BALF), and OVA-specific immunoglobulin E (IgE), IgG1, and IgG2a in serum were investigated. Cytokine production by lymphocytes isolated from peribronchial lymph nodes and histopathological changes was also examined. Results: In OVA-sensitized mice, both WG and RG reduced AHR and suppressed immune cell infiltration in bronchoalveolar regions. BALF OVA-specific IgE levels were significantly lower in RG-treated OVAsensitized mice than in the OVA-sensitized control group. WG and RG also suppressed inflammatory cytokine production by peribronchial lymphocytes. Histopathological findings showed reduced inflammatory cell infiltration and airway remodeling (e.g., epithelial hyperplasia) in WG- and RG-treated OVA mice compared with OVA controls. Conclusion: In this study, WG and RG showed antiasthmatic effects in an OVA-sensitized mouse model, and the efficacies of RG were found to be better than those of WG.
