In this study, we report the results of a study on the clinical evaluation of wrinkle improvement by developing a method for liposome of high-purity Centella asiatica extract used in pharmaceuticals and cosmetics, and a cream using the same. In order to make Centellasome-10EX stabilizing centella asiatica extract in liposome lamella vesicle, it could be completed using 5% hydrogenated lecithin and 2% sucrose distearate. The appearance of Centellasome-10EX was a creamy form of low viscosity, the color was pale yellow, and the odor had the inherent odor of the raw material. The pH was about 6.12, the specific gravity was 1.09, and the acid value was about 0.35. The content of the main constituents of centella asiatica extract contained in the liposome vesicle contains 10,800 ppm of asiatic acid, 10,900 ppm of asiaticoside, 6,000 ppm of madecasic acid, and 1,600 ppm of madecassoside, and long-term storage. There was no discoloration even at the time, and it was found that the main component remained stable thermodynamically. To mechanistically analyze the structure of the liposome vesicle of Centellasome-10EX, as a result of observation with a transmission electron microscope (Cryo-TEM), the multilayer vesicles are formed and filled with moisture, and there are 10 to 60 multilayers around it. It was confirmed that the liposome lamella vesicle was formed. As a clinical trial (in-vivo) test, the moisturizing effect of centellasome cream after application for 5 weeks was 28.3%, which was significantly increased compared to placebo. The skin elasticity effect was 13.6%, which significantly increased the moisturizing power than the placebo. The effect of improving fine wrinkles around the eyes was improved by 23.52% compared to placebo cream. Through the results of this study, it was possible to study the formulation and manufacturing method for encapsulation and stabilization of the developed Centellasome-10EX in the liposome vesicle. It is expected that the results obtained through clinical research on the wrinkle improvement effect of the cream using this can be widely used to study skin science in the cosmetic industry and to develop high-quality cosmetics with high efficacy.

Conventional medicines have usually sorted to a number of treatments such asoperation, radiotherapy, and chemotherapy. The existing anti-cancer agents, designed to eradicate cancer cells, have strong toxicities, also with leading to harmful side effects. Recently, a number of researches on natural products have been actively carried out in efforts to develop new treatments that can decrease side effects or increase anti-cancer effects. We performed this study to understand the molecular basis underlying the antitumor effects of Pharbitis nil, and Plantago asiatica, which have been used for herbal medicinal treatments against cancers in East Asia. We analyzed the effects of these medicinal herbs on proliferation and on expression of cell growth/apoptosis related molecules, with using an AGS gastric cancer cell line. The treatment of Pharbitis nil dramatically reduced cell viabilities in a dose and time-dependent manner, but Plantago asiatica didn't. FACS analysis and Annexin V staining assay also showed that Pharbitis nil induce apoptotic cell death of AGS. Expression analyses via RT-PCR and Western blots revealed that Pharbitis nil didn't increase expression of the p53 and its downstream effector p21/sup wafl/, and that the both increased expression of apoptosis related Sax and cleavage of active caspase-3 protein. We also confirmed the translocation of Sax to mitochondria. Collectively, our data demonstrate that Pharbitis nilinduce growth inhibition and apoptosis of human gastric cancer cells, and these effects are correlated with down- and up-regulation of growth-regulating apoptotic and tumor suppressor genes, respectively.

the objective of this study was to develop the Korean style fermented sausage by addition of Korean native spices(Mugwort Artemisaia asiatica ;pine needles pinus thunbergii ; Japanese pepper Zanth-oxylum prperitum ; Arrowroot pueraria hirsuta) instead of foreign-original spices(white pepper corian-der)pH of all sausages was lowered rapidly during ripening. pH reductio of sausages with foreign spices was mere rapid than that with Korean native spices except for the sausages with all mixtured Korean native spices. Aw was not affected by differentiated spices. The "a" value among Hunter Color Value of sausages that produced with mixed Korean native spices was higher than sausages with foreign spices Lactic acid bacteria rapidly increased and reached to 108cfu/g after 2 days of ripening. Korean native spices used to this work did not inhibit the inhibit of lactic acid bacteria in fermented sausages but enterobacteria did not detected after 10 days of fermentation in the sausages with mixed Korean native spices.

Effects of plantago-mucilage A (P-MA) on the immune responses were studied in ICR mice. Mice were divided into 4 groups (10 mice/group), and P-MA at doses of 7, 21 and 63 mg/kg were orally administered to mice once a day for 21 consecutive days. Mice were immunized and challenged with sheep red blood cells (SRBC). P-MA at 63 mg/kg/day significantly increased the body weight gain and the relative weights of spleen and thymus, as compared with those in controls. However, there were no significant effects on liver weight due to P-MA treatment. Plaque forming cells (PFC) and hemagglutination (HA) titers to SRBC were significantly enhanced in mice dosed at 21 and 63 mg/kg/day P-MA, as compared with those in controls. Delayed-type hypersensitivity (DTH) reaction to SRBC, phagocyte activity and circulating leukocyte were also significantly increased in mice dosed at 63 mg/kg/day P-MA. These results demonstrate that P-MA markedly enhances both humoral immune and allergic reaction to SRBC at concentrations which don't act on the relative weight of liver.

In vitro bioassays of aqueous extracts of 25 herbal species were performed by ovicidal activity against Strongvloides venuelensis. 500 mg of feces from Mongorian gerbil infected with S. venuelensis were placed into polyvinyl culture with extracts of herb and anthelmintic drugs in triplicates. Larval activity inside the polyvinyl bag was recorded microscopically at 12 hours, and every 24 hours thereafter for up to 72 hrs incubation. Eggs were not hatched within 72 hrs and degeneration was evident in the presence of extracts. The ovicidal activity characterized by the absence of L$_3$ in fecal cultures inside the polyvinyl bag. 1. Among 25 herbs, 12 herbs had ovicidal effects and caused degeneration of larvae in egg. S. angustifolia, I. helenium, A. korenum, P. tenuifolia, F. virridissima, A. asiatica, S. chinensis, A. tataricus, S. baicalensis, M. rimosa, S. glabra and Z. piperitum were the most ovicidal effect. However, P. thunbergiana, T. chinensis, C. flos, G. uralensis, C. obutusifolia, C. fortunei, A. koreana, P. grandiflorum, P. tenuifolia (Radix), P. mume and A. asphodelodes showed no ovicidal effects in vinyl bag culture. 2. Of 25 hrebs, 4 herbs had ovicidal and wormicidal effects, P. thunbergiana, C. flos, B. Striata and T. chinensis were characterized by degeneration of larvae.

Objectives : We performed this study to understand the molecular basis of the antitumor effect of Saussurea lappa, Pharbitis nil, Plantago asiatica and Taraxacum mongolicum, which have been used for cancer treatment in Korean traditional medicine. Design: We analyzed, the effect of these medicinal herbs on proliferation and apoptosis of tumor cells and its association with gene expression, We performed semi-quantitative reverse transcription-polymerase chain reaction(RT-PCR) analysis of cell cycle- and apoptosis-related genes using a gastric cancer cell line AGS. Results : Cell counting assay and $[^3H]thymidine$ uptake analysis showed that Saussurea lappa and Pharbitis nil strongly inhibit cell proliferation of AGS in a dose-dependent manner. Interestingly, gene espression assay revealed that mRNA espression levels of c-Jun, c-Fos, c-Myc, and Cyclin D1 were markedly decreased by Saussurea lappa and Pharbitis nil. Furthermore, Saussurea lappa was identified to activate expression of the p53 tumor suppressor and its downstream effector $p21^{Wafl}$, which leads to $G_1$ cell cycle arrest and apoptosis. These observations suggest that the anticancer effect of Saussurea lappa and Pharbitis nil might be associated with their regulatory capability of tumor-related gene expression.

We have investigated that a couple of soft ferrite ceramic powders having a spinal structure have shown the effect on growth and secondary metabolites production of some medicinal plants cultured in vitro. The addition of the ceramic powders as bare state to culture medium has stimulated the growth of Achyranthes japonica callus and plantlet, adventitious root of Hyoscyamus niger and Platycodon grandiflorum hairy root about 65, 75, 150 and 50%, respectively. Whereas Centella asiatica callus and plantlet, Scopolia parviflora hairy root, and Hyoscyamus albus adventitious root were not affected markedly. Moreover, the ceramic powder has enhanced the growth of H. niger adventitious roots even under conditions of irradiating alone without any direct contact between ceramic powder and media. Based on growth stimulation effect, the ceramic powders have enhanced the gross production of tropane alkaloid in H. niger adventitious root, and polyacetylene in P. grandiflorum hairy root about 35 and 30%, respectively.

Flora and distribution of vascular hygro- and hydrophytes were investigated from April to June, 1983 on the seven sampling sites along the estuary of Nagdong River. As the result, total 60 kinds of vascular plants are investigated, among them 13 kinds are aquatics; Rotala indica var. uliginosa, Myriophyllum spicatum, Allisma canalicultum, Vallisneria asiatica, Hydrilla verticillata, Potamogeton berchtoldii, P. crispus, Ruppia maritima, Phyllospadix iwatensis, Zostera marina, Juncus effusus, Phragmites communis, and Scirpus triqueter. Present hydrophytes are largely confined to the main-stream zone. The transition zone is poorly habitated by hydrophytes and considered for the distributconfined to the estuary and coastal zone. However, long-term conditions of salinity gradient appear to be primarily responsible for the present flora and distribution.

This study was conducted to evaluate effects of dietary herbal extracts mixturetMiracle" included Angelicae Gigantis Radix, Rehmanniae Radix, Cnidii Rhizoma, Glycyrrhizae Radix, Schizandrae Fructus, Plantago asiatica and Dioscoreae Radix) on the productivities of lactating sowsand growth performance and hematological characteristics of piglets. Twenty seven sows (Yorkshire ${\times}$ Landrace ${\times}$ Duroc, 1 to 3 parities) were used in a 21 day old trial. Dietary treatments included 1) CON (control; basal diet), 2) HPMO.l (basal diet + herbal plant mixture 0.1 %) and 3) HPMO.2 (basal diet + herbal plant mixture 0.2 %). Backfat thickness losses from farrowing to weaning was decreased in HPM treatmentscompared with control(linear effect, P $\leq$ 0.003). ADFI was decreased in sows fed herbal plant mixture(linear effect, P < 0.05). Also, treatments of dietary herbal plant mixture reduced day of return to estrus compared with control(linear effect, P < 0.05). Energy digestibility in HPM treatments were higher than control(linear effect, P $\leq$ 0.05). In piglets, weight gain(P > 0.05) and survivability(P> 0.05) after weaning werenot affected by treatments. No statistical differences were found(P> 0.05) forhematological characteristics in piglets. In conclusion, dietary herbal plant mixture reduces backfat thickness losses and day of return to estrus and improves energy digestibility in lactating sows.
