Platelet anti-aggregating activities were evaluated with three combined crude drug preparations which have been used for 'eahyul'-one of the pathological concept in oriental medicine presumably concerning blood stasis or stagnant syndrome. The water extract of each combined preparation and each component plant was tested for their effects against ADP, arachidonic acid (AA) or collagen induced rat platelet aggregations. Mild inhibitory activities were observed with all the three tested preparations, Kaechibokryung-Hwan, Dangkqijakyak-San and Ohnkyung-Tang, and the component plants which are included in at least two of the above preparations.

Sponges are host organisms for various symbiotic microorganisms such as archaea, bacteria, cyano-bacteria and microalgae. Sponges are also sources of a wide variety of useful natural products like cyto-toxins. antifouling agents, antibiotics, and anti-inflammatory and antiviral compounds, Symbiotic microorganisms is sponges can be sources of various natural products, because metabolites previously ascribed to sponges have recently been demonstrated to be biosynthesized by symbionts. If a symbiotic microorganisms from which some natural products are derived can be cultured, the microorganism could be used in a mass production of the bioactive comopounds. We summarize recent research on iso-lation and cultivation of sponge-symbiotic microorganisms and the symbiotic relationship.

The use of medicinal food, food supplements and nutraceuticals is steadily increasing worldwide. These products are derived from a variety of sources of ethnic traditions and new research findings. They are being utilised in a diverse range of preventive and therapeutic situations. Because of this increased interest there is greater use of multiple natural products simultaneously. The use of combinations needs to be treated with circumspection. Mixing may have no unexpected consequences or it may have rather unanticipated beneficial outcomes. Just as likely are deleterious effects from combining the intake of natural products. Recent research has been quite useful in the characterisation of the consequences of some of these combinations and examples will be presented.

Due to environmental pollution and human hazards of some synthetic dyes, the global fashion companies are increasingly interested in eco-friendly products, especially natural dye. For the globalization of natural dyeing industry based on this concern, however, there are some deficiencies of standardization, specification, and conformity assessment on natural dyestuffs as well as natural dyeing process. These obstacles should be not only studied but also defined for a commercial transaction. Accordingly, a study for conformity assessment on commercialized natural dyestuffs (red) was conducted by HPLC analysis in this study. As the results of HPLC analysis, alizarin and purpurin, representative index ingredients, were detected in most of the samples, but the index ingredient content in each sample was different. In addition, some samples showed the variety of peaks including the index ingredients and others. It was inferred that the representative index ingredients could be used on the traceability of natural sourced dyestuffs. These results are related to the index ingredient consistency, standardization, and reproducibility of natural dyed products including such as yarns, fabrics, garments, and so on. Therefore, the present study was demonstrated that in order to determine the conformity assessment system for the satisfaction of all stakeholders, the offering of information on the origin, manufacturing process, and index ingredient content of natural dyes should be prioritized.

Constitutive cyclooxygenase (COX-I) is present in cells under physiological conditions, whereas inducible cyclooxygenase (COX-II) is induced by some cytokines, mitogens, and endotoxin presumably in pathological conditions such as inflammation. We have evaluated the inhibitory effects of solvent fractionated extracts of natural products on the activities of COX-I and COX-II. Oxygen uptake COX assay was performed, as a primary screening from the tissue extracts of bovine seminal vesicles (BSV), by monitoring the initial rate of oxygen uptake using an oxygen electrode. Additionally, we evaluated plant extracts for the inhibitory effects of COX-I (in HEL cells) and COX-II (in lipopolysaccharide activated J774A.1 macrophages) using thin layer chromatography of prostanoids produced from $^{14}C-labelled$ arachidonic acid (AA). The use of such models of COX-I and COX-II assay will lead to the identification of specific inhibitors of cyclooxygenases with presumably less side effects than present therapies. Inhibitory effects of 50 kinds of plant extracts on the COX-I and COX-II activities were determined and the active fractions were found in the ethyl acetate fractions of Dryopteris crassirhizoma (roots), Amomum cardamomum (roots), Triticum aestivum (seeds), Perilla sikokiana (leaves), Anemarrhena asphodeloides (roots). Especially, the ethyl acetate fraction of Dryopteris crassirhizoma (roots), which exhibited the strong inhibition against BSV COX $(IC_{50},\;65.4\;{\mu}g/ml)$, COX-I $(IC_{50},\;8.5\;{\mu}g/ml)$, and COX-II $(IC_{50},\;17.2\;{\mu}g/ml)$, is under investigation to isolate active principles using activity-guided fractionation method.

Total fourty-four medicinal plants described in old literatures to be hepatotonic were evaluated their potential hepatotonic activities against an animal model of hepatitis. Tweenty-seven plants extracts appeared to be significant hepatotonic activities, whereas twelve plants extracts exhibited rather some toxicity. And five plants extracts showed no significant hapatotonic activities and toxicity.

The present study was performed to examine the effects of oral administrations of Panax ginseng(PG) and P. quinquefolium(PQ) roots on hemodynamics and body temperature in healthy young men, since it was claimed that PG raises heat whereas PQ lowers heat by some ethnopharmacologists. The 42 healthy young male volunteers were divided into live groups. which were treated with mineral water(control), each high (9.0 g) and low (4.5 g) dose of PG and PQ. (omitted)

Legumes are important agricultural and commercial crops characterized by root nodules formed as a result of the symbiotic relationship with nitrogen-fixing rhizobia. Due to the economic significance the chemistry of some of these species has been well recognized. Soybeans and processed soy products, which contain isoflavonoids and saponins, are of wide interest for their multifacted biological effects. (omitted)
