Genetic diversity and genetic structures were estimated in seven natural populations of Phellodendron amurense Rupr in South Korea using ISSR markers. The average of polymorphic loci per primer and the proportion of polymorphic loci per population were 4.5 and 78.8% respectively with total 27 polymorphic loci from 6 ISSR primers. The Shannon's diversity index(I) was 0.421 and the expected heterozygosity($H_e$) was 0.285, which was similar to the heterozygosity (hs =0.287) inferred by Bayesian method. In AMOVA, 7.6% of total genetic variation in the populations was resulted from the genetic difference among populations and the other 92.4% was resulted from the difference among individuals within populations. Genetic differentiation(${\theta}^{II}$) and inbreeding coefficient(f) for total population were estimated to be 0.066 and 0.479 by Bayesian method respectively. In Bayesian clustering analysis, seven populations were assigned into three groups. This result was similar to the results of genetic relationships by UPGMA and PCA. The first group included Hwachoen, Gapyeong, Bongpyeong and Yongpyeong population, and the second included two populations in Sancheong region. Muju population was discretely assigned into the third group in spite of the geographically short distance from the Sancheong region. There was no significant correlation between genetic relationship and geographic distribution among populations in Mantel's test. For conservation of the phellodendron trees, it would be effective to consider the findings resulted from this study with ecological traits and life histories of this species.

Yellow dye-stuffs in natural plant were extracted from a gardenia, saffron, safflower, amur tree and pagoda. And then they were used to color Korean handmade paper(Hanji) on using a mordant. The results of the degree of discoloration are as follows. 1. As for a gardenia(Gardenia jasminodes Ellis for. grandiflora Makino), the effects of coloring were outstanding in the acid area. But for the preservation, it might be desirable that used a lye in a dye-stuff obtained at $40{\pm}5^{\circ}C$. 2. As for saffron(Curcuma longa L.), when used alum as a mordant, it was colored to a medium yellow color with green color. But easily discolorated and was not desirable. And, it didn't fit in a dye-stuff of Hanji. 3. For safflower(Carthamus tinctorius L.), when pH was in the low acid it was colored to the cleaner yellow color. It was the distinction of discoloration that the degree of brightness's increase was low. 4. For amur cork-tree(Phellodendron amurense Rupr.), the effects of yellow coloring were great in the areas of acidity and alkali. But, when used alum, the degree of the discoloration was high and was not effective. 5. For pagoda tree(Styphnolobium Japonica L.), using a calcium hydroxide as a mordant, enabled the more than average yellow to be gained. The degree of discoloration was good.

We examined the effect of pretreatments on seed germination, seedling growth, optimal seedling density of Phellodendron amurense. The seeds were carefully purified after collection in late Oct. from natural population at Mt. Chiri. For the evaluation of pretreatment effects, seeds were sowed in an experimental nursery after being stored in open ground($2{\sim}8^{\circ}C$) with soaking in 20% $H_2O_2$, 50-fold pon-pon solution, cold moist stratification in refrigerator($2{\sim}4^{\circ}C$) and dry storage in roam temperature($4{\sim}18^{\circ}C$), respectively, For the effect of growth density of seedlings, seedlings germinated in nursery were precisely controlled with 53, 104, 220, 380 seedlings per $m^2$. Among pretreatments for the promotion of germination rate, pon-pon treatment(68.8%) was highest, the others were higher than that in dry storage(2.3%), and these seed pretreatment methods were significantly different at 1% level. The height growth of seedlings showed the most vigor from Jun.12 to Jul. 8, and from Jul.20 to Aug. 2, and it reached to 72.8% of height growth. In case of 1-0 seedling, although seedling density per $m^2$ was increased, seedling growth was decreased. The optimal seedling density was 104 seedlings per $m^2$. The standard seedlings for plantation were above height 55cm, root collar diameter 8.1mm, and root length 21cm. These results demonstrated that seed of P. amurense requires stratification for the germination promotion.

Objectives: This study was evaluated to elucidate the inhibitory potential of Imyosan(IMS) and its components, Phellodendri Cortex(PC: Phellodendron amurense Rupr., Hwangbaek in Korean) and Atractylodis Rhizoma(AR: Atratylodes lancea D.C., Changchool in Korean), on human aortic smooth muscle cells(HASMC) migration and production of matrix metalloproteinase (MMP)-2 and MMP-9 by TNF-${\alpha}$ treatment. Methods: Cytotoxic activity of IMS and its components on HASMC was using 5-(3-caroboxy meth-oxyphenyl)-2H-tetra-zolium inner salt(MTS) assay. Effect of IMS, PC and AR on TNF-${\alpha}$-induced HASMC migration underside of matrigel filter was stained with hematoxylin-eosin. And total number of cells that migrated to the underside of the filter was counted. MMP-2 and MMP-9 activity was evaluated by gelatin zymography assay. Results: The matrigel migration assay showed that IMS effectively inhibited the TNF-${\alpha}$-induced migration of HASMC. Moreover, IMS significantly inhibited MMP-9 activity. Our present study demonstrates that IMS and its components inhibit TNF-${\alpha}$-induced HASMC migration and MMP-9 activity. The inhibitory effect of IMS extract is more potent than that of its component herb extracts. Conclusions: These results provide evidence that IMS has multiple effects in the inhibition of HASMC migration and may offer a therapeutic approach to block HASMC migration.

The purpose of this study was to investigate the effect of Imyosan on apoptosis in human colorectal cancer HCT116 cells. Phellodendron amurense Rupr. and Atratylodes lancea D.C. compose Imyosan. First of all, to study the cytotoxic effect of methanol extract of Imyosan (IMS-MeOH) on HCT116 cells, the cells were treated with various concentrations of IMS-MeOH and then cell viability was determined by XTT reduction method. IMS-MeOH reduced viability of HCT116 cells in a dose and time-dependent manner. To confirm the induction of apoptosis, the c1eavage of poly ADP-ribose polymerase (PARP), a substrate for caspase-3 and a typical sign of apoptosis, and the activation of caspase-3, procaspase-8 and procaspase-9 were examined by western blot analysis. IMS-MeOH decreased procaspase-3, procaspase-8 and procaspase-9 levels in a dose-dependent manner and induced the clevage of PARP. IMS-MeOH triggered the mitochondrial apoptotic signaling by increasing the release of cytochrome c from mitochondria to cytosol. Furthermore, IMS-MeOH also downregulated the anti-apoptotic Bcl-2 and upregulated the pro-apoptotic-Bax. Therefore, these results suggest that IMS-MeOH induced HCT1l6 cell death through the mitochondrial pathway. To explore whether the activities of caspases was required for induction of apoptosis by IMS-MeOH, caspase-3, -8, -9 activity measured by using substrates, respectively. IMS-MeOH increased caspase-3, -8, -9 activity. Co-treatment with inhibitors of caspase-3, -8, -9 and IMS-MeOH significantly blocked IMS-MeOH-triggered apoptosis in HCT1l6 cells. These results suggest that IMS-MeOH induces caspases-mediated apoptosis.

Angiotensin converting enzyme(ACE) belongs to the class of zinc protease and plays an important role in the regulation of blood pressure. In this experiment, we investigated the inhibitory activities of ninety four plant extracts on ACE. The extracts were prepared by water and refluxing with 70% and 100% methanol. Among the extracts, two plant extracts such as Cassia tora, Persicaria cochinchinensis Kitagawa showed more than 60% inhibitory activities, and Foeniculum vulgare Gaertner, Scutellaria baicalensis Georgl, Caragana sinica (Buchoz) Rehder, Inula britannica var. chinensis showed $45.2{\sim}49.7%$ inhibitory activities. Twenty eight plant extracts such as Hemerocallis fulva L, Camptotheca acuminata Decne, Inula britannica var. chinensis, Xanthium strumarium, Polygonatum odoratum, Phellodendron amurense Rupr, Coix lachryma-jobi var. mayuen, Prunus ansu, Hibiscus mutabilis L, Thchosanthes kirilowii, Helianthus annuus, Juglans sinensis showed $30.3{\sim}39.7%$ Inhibitory activities. These results suggest that plant extracts which contain high ACE inhibitory activities may be useful as anti-hypertension agents and to the treatment of hypertension.
