The study was carried out to establish an improved protocol for shoot organogenesis and plant regeneration from leaf explant cultures of Scrophularia buergeriana M. with the treatment of ethylene inhibitors [silver nitrate (AgNO$_3$), aminoethox-yvinylglycine (AVG), Cobalt chloride (CoCl$_2$)]. The regenerated shoots obtained from leaf explant cultures on MS medium containing 2 mg/l BAP, The additions of AgNO$_3$. AVG and CoC1$_2$ substantially improved the shoot regeneration frequency, at the optimal concentration of 7 mg/L, 7 mg/L, and 3 mg/L respectively, The regenerated shoots could be easily rooted with 0.1 mg/L IBA treatment. The noted plants were hardened and transferred to vermiculite with a 85% survival rate where they grew normally.

Scrophularia buergeriana Misrule has been contaminated with various pathogens in condition of field and storage period. This study was carried out for production of multiple stress resistance plant containing disease resistance that CGST gene expressed in transgenic Scrophularia buergeriana Misrule genome. Glutathione S-Transferases (GSTs) detoxify endobiotic and xenobiotic compounds by covalent linking of tripeptide glutathione to hydrophobic substrate. GST enzymes have been identified and characterized in insects, bacteria, and many plant species. A cDNA clone of GST was introduced into Scrophularia buergeriana Miquel by transformation with Agrobacterium tumefaciences. In coporation of the CGST gene into S. buergeriana Misrule was confirmed by PCR analysis of genomic DNA. Influence of exposure to darkness on the regeneration potential and transformation frequence were assessed. The activity of GST in transgenic plants was two times higher than that of non-transgenic plants. As a result of anti-microbe assays, the crude extract protein of transgenic plants showed the antimicrobial effects higher than control plants.

objectives: We investigated the moisturizing and cooling effects of the cosmetic product with Scrophularia Buergeriana, Poria Cocos, Lonicera Japonica, Portulaca Oleracea and Ginko Biloba extract on human skin by using non-invasive instrument. Methods: We measured physiological effects after volunteers(female, n=5) applied the cosmetic product containing the extract of oriental herbs. The forearm skin moisturization was measured with $Corneometer^{\circledR}$ CM825 after 15min, 3hr, and 6hr. The forearm skin surface roughness was with Scanning electron microscopy after 15min, and 6hr. The face skin temperatures cooling and microcirculation effects were measured with ThermaCAMTM PM525 and LDl-Periscan PlM II after 15min, and 30min. Results: The forearm skin moisturization was imcreased 108% after 15min. The forearm skin surface roughness was decreased significantly after 15min. The face skin temperatures were cooling down to $30.7^{\circ}C$. The face skin microcirculation effect was normalized time-dependently. Conclusions: We concluded that cosmetic product containing the extract of Scrophularia Buergeriana, Poria Cocos, Lonicera Japonica, Portulaca Oleracea and Ginko Biloba had a moisturization effect and improving the surface roughness, temperature and microcirculation on the human skin.

Total 90 species of medicinal plants were surveyed to see if they have any suppressive effects on the dinsity of M hapla at the exhibition field in the Chinan medicinal herbs experiment station. In 70 species including Achyranthes japonica, root-knot and/or egg sac of M. hapla was not found and these plants were planted in C. lanceolata field to check the degree of M. hapla infection. In 26 species including A. japonica, M. hapla infection was not observed. Simultaneously, 30 species were planted in pots to find out degree of infection by M. hapla. Dianthus chinensis, Rudbeckia bicolor, Sedum kantschaticum, Ricinus communis, Anemarrhena asphodeloides, Malva verticillate, Chelidonium majus, Sesamum indicum, Agrimonia pilosa, Geum aleppicum, Sanguisorba officinalis and Scrophularia buergeriana were free from infection. While the number of galls and density of M. hapla in soil were higher to high innoculation density, and the growth of C. lanceolata was rower.

Possible nematicidal effects of plant extracts of 25 species uninfected by M. hapla were observed at the 5 times dilutions in all treatments and at the 10 times dilutions in Anemarrhena asphodeloides, Acorus calamus, Achyranthes japonica, Agrimonia pilosa, Dianthus chinensis, Geum aleppicum, Houttuynia cordate, Rudbeckia bicolor, Ricinus communis, Scrophularia buergeriana, Sesamum iindicum, Sedum kamtschaticum, and Sanguisorba officinalis. The 13 species plant extracts of 5 times dilutions were evaluated for the suppression effects on reducing densities of M. hapla by treating to C. lanceolata sown and transplanted later in pots. All the plant extracts showed suppressive effects on M. hapla except for.A. pilosa. The suppressive effects of A. asphodeloides, A. japonica, A. calamus, D. chinensis, R. communis, and S. buergeriana were over 80%. When the selected plants had been incorporated into the soil before C. lanceolata was sown, the numbers of root galls, egg sacs and $J_{2}$ appeared lower in the treatment of 12 plant species than in control except for S. indicum. But the suppressive effects were lower than the effects of selected plants being cultivated simultaneously in the field. A. calamus and A. japonica exhibited over 70% suppressive effects, among the tested plants.
