To develop new therapy for prevention and treatment of hair loss is very important according to increase of the number of hair loss people. The aim of this study was to investigate the hair growth promoting effects of pectin lyase-modified red ginseng extract (GS-E3D). We examined antioxidant and anti-inflammatory effects, human hair dermal papilla cells (HHDPC) proliferation, and testoterone-induced $5{\alpha}$-reductase inhibitory effects. GS-E3D show not only 1,1-diphenyl-2-picryhydrazyl (DPPH) radical scavenging activity and xanthine oxidase inhibitory effects as an anti-oxidant property, but also lip-oxygenase and hyaluronidase inhibitory effects as an anti-inflammatory property. Human hair dermal papilla cells proliferation by GS-E3D was higher than those of minoxidil or finasteride, using the positive controls. Moreover, GS-E3D exhibited $5{\alpha}$-reductase inhibitory activities after stimulating by testoterone. The present results indicate that GS-E3D has a potential to be as an hair growth promoting agent for cosmetic materials.

Ginseng root has been considered to prevent neuronal degeneration associated with brain ischemia, but experimental proof in support of this speculation is limited. Moreover, few studies have compared the neuroprotective actions of ginseng ingredients with those of peptide growth factors and cytokines isf vivo. Using a gerbil forebrain ischemia model, we demonstrated that the oral administration of red ginseng powder before an ischemic insult prevents delayed neuronal death in the hippocampal CAI field and that a neuroprotective molecule within red ginseng powder is ginsenoside Rbl. The neurotrophic effect of ginsenoside Rbl, when examined in the gerbil ischemia model and in neuronal cultures was as potent as or more potent than the effects of epidermal growth factor, ciliary neurotrophic factor, erythropoietin, prosaposin, interleukin-6 and interleukin-3. Besides the protection of hippocampal CAI neurons against brain ischemia/repercussion injuries, ginsenoside Rbl was shown to prevent place navigation disability, cortical infarction and secondary thalamic degeneration in stroke-prone spontaneous hypertensive rats with permanent occlusion of the unilateral middle cerebral artery distal to the striate branches. These findings may validate the empirical use of ginseng root for the treatment of cerebrovascular diseases

This study was carried out to investigate the effect of ginseng-cake on growth and biochemical components of rats. The content of crude protein in ginseng-cake was 17.2% as dry basis. Methionine, isoleuine and valine were limiting amino acids in order and arginine was 23.6% in total amino acids. Body weight gain, food efficiency ratio, organ weight and biochemical components in plasma were significantly lower in ginseng-cake based diet group than in control diet group and those of ginseng-cake diet group supplemented with methionine, isoleucine and valine were significantly increased than those of ginseng-cake based diet group, but 소id not reach to those of control diet group.

This study was conducted to investigate the effects of ginseng extracts and their fractions on the 9rowth of Escherichia coli and its glucose consumption. Considerable amount of impurities such as sugar, Protein, lipids and minerals other than saponins were contained in n-butanol extracts which are generally referred to be crude saponins. Sucrose and maltose were contained as major sugars In ginseng extracts and their water soluble fractions. Arginine and potassium were also contained as major amino acid and mineral in those fractions, respectively. Though the glucose consumption and growth of Escherichia coli were enhanced by ginseng extracts and their water soluble fractions those were retarded by ether soluble fractions and n-butanol fractions.

This study was conducted to elucidate the effect of physical properties of soil in nursery bed with different densities on growth of ginseng seedling. Stem length, leaf length and leaf width of ginseng seedling showed the decreasing tendency with increasing the hardness of the nursery soil. Fresh root weight per seedling and number of available seedlings were increased significantly with decrease of the soil hardness. For solid, liquid phases, bulk density and hardness of soil, negative correlations were shown in stem length, leaf length, leaf width, root weight per seeding, and number t of available seedlings. On the other hand, gas phase, air permeability and porosity of soil had positive correlations with stem length, leaf length, leaf width, root weight per seedling and number of available seedlings. Key words Yang-Jik nursery, ginseng seedling, soil physical properties.

This study was attempted to screen the cytotoxic activity of petroleum ether ex- tract from panax ginseng root against human colon cancer cells. Two extracts of panax ginseng root, crude and partially purified, were used for this experiment. The crude extract was prepared by extraction with petroleum ether using Soxhlet aparatus for 12 to 15 hours from panax ginseng and the extract was partially purified by silicic acid column with mixture of petroleum ether: ethyl ether (70 : 30, v/v). Three species of human colon cancer cells, HRT-18, HCT-48 and HT-29, were maintained in DMEM (Dulbecco's modified Eagle medium), and the cells were cultured in DMEM containing serial concentration of the crude or partially purified fraction to observe the cytotoxic activity of the both extracts. The effects of incubation time and concentration of the both extracts in culture medium against the growth of the each cancer cell were determined. The results obtained are summarized as follows: 1. The doubling times of the HRT-18, HCT-48 and HT-29 cells were about 20, 24 and 22 hours, respectively. 2, The inhibitory effects of the crude extract on the growth of cancer cells were increased according to the rise of concentration of the extract and incubation time. 3. The inhibitory effect of partially purified fraction on the growth of HRT-18 cell was about 4 times stronger than that of the crude extract under same experimental condition. 4 The inhibitory effects of the crude and purified fraction on the growth of each cancer cell were shown difference by the kind of the cancer cell. In view of the above results, it could be said that the petroleum ether extract of panax ginseng root inhibited the division of the human colon cancer cell, in vitro.

인삼모상근의 생장과 ginsenosides의 함량을 높이기 위하여 생장조절제가 첨가되지 않은 1/2 MS 배지에 jasmonic acid와 methyl jasmonate의 농도와 처리시기를 달리하여 인삼모상근 KGHR울 세포주를 배양하였다. 인삼모상근 생장은jasmonic acid와 methyl jasmonate 모두 1$\mu\textrm{m}$ 농도에서 가장 양호하였으며 30$\mu\textrm{m}$ 이상 농도가 증가할수록 모상근생장이 감소하였다. 그러나 생장이 낮았던 jasmonic acid 10$\mu\textrm{m}$ 처리구와 methyl jasmonate 50$\mu\textrm{m}$에서 ginsenosides 함량과 생산성이 더 높았다. 배양시기별로 jasmonic acid와 methyl jasmonate의 처리 효과는 jasmonic acid는 배양 후4주, methyl jasmonate는 3주에 처리하는 것이 ginsenosides의 함량과 생산성을 높이는데 효과적이었다.

Five years old ginseng plant (Panax ginseng) with ten stems from six bud base was found in a ginseng plantation. Stems were emerged even around the rhizome base. Growth status of all stems were poor. The length of some stems was shorter than that of petiole. The shorter the stem length is the longer the petiol length.
