This study was undertaken to examine the feasibility of black locust (Robinia pseudoacacia) as substrates for several edible mushrooms. For the cultivation of several edible and/or medicinal fungi on black locust, optimum bulk densities, synthetic or semisynthetic additives, natural additives and pretreatment methods were investigated. Fruit body yields of the fungi on various sawdust media composed of different wood species were also analyzed for testing the capability of black locust as a substrate for mushroom production. Mycelial growths decreased proportional when the bulk density increased. The most suitable carbon and nitrogen sources as additives to promote the mycelial growth were sucrose (2%, w/w) and ammonium phosphate (0.2%, w/w) respectively. When corn-powder and beer-waste as natural additives were added to sawdust of black locust showed the significant growth of mycelia. And the optimum mixing ratio was 10:2:1 (sawdust: corn-powder: beer-waste, w/w). Black locust after cold water treatment showed the outstanding mycelial growths. Any significant changes of pH, moisture content (%) and dry-weight losses (%) could not be found among culture substrates (sawdust of black locust, oak and poplar wood) examined before and after harvesting of fruit bodies. Yield of fruit bodies on black locust culture media were comparable with those culture media composed with oak and poplar wood. The present work indicated strongly the potentiality of black locust as raw materials for edible and medicinal mushrooms.

Medicinal uses of edible and other plants for prevention and cure of obesity and overweight associated metabolic and mental health problems have since long been known to scholars and practitioners of Ayurvedic and other traditionally known system of medicine. Modernized versions of numerous edible plant derived formulations mentioned in ancient Ayurvedic texts are at present some of the most popular, or best selling, herbal remedies in India and numerous other countries suffering from double burden of diseases caused by malnutrition and obesity. Preclinical and clinical information now available on edible plants and their bioactive constituents justify traditionally known medicinal uses of products derived from them for prevention and cure of obesity associated type-2 diabetes, psychopathologies and other health problems. Such information now available on a few edible Ayurvedic plants and their formulations and suggesting that their stress response regulating effects are involved in their broad spectrums of bioactivity profiles are summarized in this communication. Implications of recent physiological and pharmacological observations made with numerous phytochemicals isolated from edible plants for better understanding of traditionally known medicinal uses of herbal remedies are also pointed out.

The present study has been undertaken to detect edible medicinal plants with antineoplastic property on the basic of a number of traditional Korean medical literatures, besides studies on development of anti-cancer medical wild plants growing in Korea and to prove experimentally their efficacy by in vitro and in vivo tests.235 species from 45 family 79 genus were screened primarily as edible sources of antitumor effect. Among those the crude. extracts of 40 spp. showed considerable cytotoxicity in vitro and especially Pegangkuen(Patrinia scabiosaefolia), Deod-eog(Codonopsis lanceolata), Okssusu(Zea may), and Geureong(Eragrositis ferru-ginea) exhibited significant antitumor activity against sarcoma 180 asites mice. However, additional researches should be mode for the confirmation of their availability as antitumor plants.

Thalictrum rochebrunianum var. grandisepalum (TRG) is a Korean endemic plant, and it is widely used for edible, medicinal, landscape materials. In this study, we examined the protein and mRNA expression levels of MITF, tyrosinase, TRP-1 and TRP-2 by TRG extract (TRGE) in IBMX-treated melanocytes to evaluate the possibility of using TRG as a whitening material. IBMX were reported as melanin synthesis enhancers. It could increase intracellular melanin synthesis by activation of the microphthalmia-associated transcription factor (MITF) signaling pathway. TRGE did not show cytotoxicity at concentrations below $100{\mu}g/ml$ in B16F10 cells. TREG dose-dependently inhibited protein and mRNA levels of MITF, tyrosinase, TRP-1 and TRP-2. Therefore, we suggest that TRGE is an important natural resource for cosmetic raw materials for whitening function.

We investigated traditional knowledge about ethnobotanical uses around national parks in the northern areas of Province Gyeongsangbuk-do, with the focus on the Sobeaksan National Park area. Interviews were carried out to 138 residents at 42 places from 7 counties and/or cities, and verified species and usage information were categorized by taxonomic groups, usage, and used parts. The ethnobotanical species of the regions consisted of a total of 277 taxa: 244 species, 3 subspecies, 28 varieties, and 2 forma in 213 genera of 79 families. The significant native plants included one Endangered Species (Paeonia obovata Max.) and four endemic species (Salix hallaisanensis H. Lev., Aconitum pseudolaeve Nakai, Paulownia coreana Uyeki, and Cirsium setidens (Dunn) Nakai, Sasa coreana Nakai). About 17 Approved Species for Delivering Overseas designated by Korea Ministry of Environment have been also traditionally valuable in the regions. The main usage of the plants were edible (185 taxa) and medicinal (175 taxa). Leaves were most commonly used parts (109 taxa), followed by stems (73 taxa), fruits (69 taxa), roots (67 taxa), and wholes (57 taxa). The traditional usage of plants were diverse as those useful parts. Leaves, fruits and seeds were used as edible and medicinal; sprouts (young shoots) were mainly used as edible; but roots and flowers were used as medicinal. The study does not only provides examples of traditional uses of native plants, but also facilitates sustainable managements and developments of ethnobotanical knowledge for the contemporary society.

Plant-based vaccines possess some advantages over other types of vaccine biotechnology such as safety, low cost of mass vaccination programs, and wider use of vaccines for medicine. This study was undertaken to develop the transgenic maize as edible vaccine candidates for humans. The immature embryos of HiII genotype were inoculated with A. tumefaciens strain C58C1 containing the binary vectors (V662 or V663). The vectors carrying nptII gene as selection marker and scEDIII (V662) or wCTB-scEDIII (V663) target gene, which code EIII proteins inhibite viral adsorption by cells. In total, 721 maize immature embryos were transformed and twenty-two putative transgenic plants were regenerated after 12 weeks selection regime. Of them, two- and six-plants were proved to be integrated with scEDIII and wCTB-scEDIII genes, respectively, by Southern blot analysis. However, only one plant (V662-29-3864) can express the gene of interest confirmed by Northern blot analysis. These results demonstrated that this plant could be used as a candidated source of the vaccine production.

Thirteen edible plants previously reported to show inhibitory activities on farnesyl protein transferase (FPTase) and phosphatase of the regenerating liver-3 (PRL-3) were evaluated for inhibitory activity on the proliferation of human umbilical vein endothelial cells (HUVECs). Four plant extracts, Oenothera erythrosepala, Perilla frutescens, Panicum miliaceum, and Quercus acutissima, significantly inhibited the proliferation of HUVECs induced by the basic fibroblast growth factor (bFGF) without cytotoxicity at 100 ${\mu}g/mL$. Myristica fragrans, Rosmarinus officinalis, and Syringa patula also showed inhibitory activity on the proliferation with only mild cytotoxicity.

Pinus densiflora, the Korean Red Pine, is the predominant tree species of the cool, temperate forests of northeast Asia, occurring in pure stands across Korea, Japan, and parts of northern China and Russia. Pinus densiflora leaves, pollen, and bark have been widely used for traditional medicine, or edible purposes. However, pine cones contain many bioactive phytochemicals, but they are rarely used as natural raw materials. This study was conducted to evaluated the anti-inflammatory effect of pine cone extracts and its possbility of natural sources were evaluated. Pine cones were extracted with 80% methanol, concentrated and then partitioned with ethyl acetate, and the organic layer was used as a sample. The Pine cone Ethyl acetate Fraction (PEF) showed no toxicity to RAW 264.7 cells at a concentration of less than $50{\mu}g/ml$. PEF inhibited the production of nitric oxide (NO) in RAW 264.7 cells treated with lipopolysaccharide (LPS). Also, It suppressed the expression of cyclooxygenase-2 (COX-2), inducible nitric oxide synthase (iNOS) and transcription of nuclear factor-kappa B (NF-${\kappa}B$). These results suggest that pine cones can be used as an effective natural material for anti-inflammatory agent.
