Effects of dammarane glycosides of Panax ginseng on primary cultured chicken embryonic brain cells were studied by microscopic observation and determination of the activity of pyruvate dehydrogenase complex (PDHC). Brain cells were prepared from the brain of 10-day-old chicken embryo and cultured with either a standard medium consisted of 85% Dulbecco's Modified Eagle Medium (DMEM), 10% horse serum and 5% chicken embryonic extracts or a deficient medium consisted of 90% DMEM and 10% horse serum. It was observed that dammarane glycosides of Panax ginseng seemed to show the tendency to stimulate the neurite outgrowth of brain cells which were cultured with a deficient medium under microscopic observation. The activity of PDHC in brain cells cultured with a deficient medium was increased by dammarane glycosides of Panax ginseng.

Objectives : The purpose of this study was to obtain an objective differentiating method for various types of Panax ginseng: ginseng, cultivated wild ginseng, and natural wild ginseng which are distinctive according to their growing environment. Methods : The roots, stem, and leaves of several types of ginseng were collected and comparative analysis of proteome was conducted on each part using 2-DE and the results examined. Results : 1. Proteome images of the respective parts within the samples showed spot-matching in most cases, suggesting that they are genetically identical panax ginseng. 2. Similar distribution patters were seen within the different parts of the Panax ginseng: ginseng, Chinese cultivated wild ginseng, and the 5 and 10 years old Korean cultivated wild ginseng. 3. For a quantitative evaluation of spots showing differences among the samples, 102 spots from the roots, 109 spots from the stems, and 132 spots form the leaves which showed a difference were selected and centrifugal identification was conducted. 4. Peculiar proteins from each respective part of the Panax ginseng were identified and the top 20 spots with significant differences were selected and analyzed in order to provide a differentiation rate among the samples. The accuracy rate ranged between 23.0-38.8%. 5. Differentiation rate of the top 10 spots with significant differences showed a 50-85% accuracy rate, and the differentiation rate was especially high for the stem of Chinese cultivated wild ginseng and Korean cultivated wild ginseng.

Panax ginseng, also called Asian or Korean ginseng, has long been traditionally used in Korea and China to treat various diseases. The major active ingredients of P. ginseng are ginsenosides, which have been shown to have a variety of therapeutic effects, including antioxidation, anti-inflammatory, vasorelaxation, antiallergic, antidiabetic, and anticancer. To date, approximately 40 ginsenoside components have been reported. Current research is concentrating on using a single ginseng compound, one of the ginsenosides, instead of the total ginseng compounds, to determine the mechanisms of ginseng and ginsenosides. Recent in vitro and in vivo results show that ginseng has beneficial effects on cardiac and vascular diseases through efficacy, including antioxidation, control of vasomotor function, modulation of ion channels and signal transduction, improvement of lipid profiles, adjustment of blood pressure, improvement in cardiac function, and reduction in platelet adhesion. This review aims to provide valuable information on the traditional uses of ginseng and ginsenosides, their therapeutic applications in animal models and humans, and the pharmacological action of ginseng and ginsenosides.

Ginseng Is renowned for both its medicinal and herbal uses and successful cultivation of Panax ginseng in Asia and Panax quinquefolium in North America has until recently taken place in the native geographical ranges of the plants. As a consequence of the potential high capital return and anticipated increases in consumer consumption, commercial cultivation of American ginseng now occurs well outside the native range of the plant in North America. In fact, the region of greatest expansion of cultivation is in the semi-arid interior region of British Columbia, Canada. Linked with this expansion is the potential domination of the ginseng industry by agricultural corporations. In the interior of British Columbia, the native deciduous forest environment of eastern North America is simulated with elevated polypropylene shade and a surface covering of straw mulch. The architecture of these environments is designed to permit maximum machinery usage and to minimize labor requirements. Further, with only a four- years growth cycle, plant densities in the gardens are high. In this hot, semi-arid environment, producers believe they have a competitive advantage over other regions in North America because of the low precipitation rates. This helps to minimize atmospheric humidity such that the conditions for fungal disease development are reduced. If soil moisture level become limited, supplemental water can be provided by irrigation. The nature of the radiation and energy balance regimes of the shade and many environments promotes high soil moisture levels. Also, the modified environment redlines soil heating. This can result in an aerial environment for the plant that is stressful and a rooting zone environment that is suloptimal. The challenge of further refining the man modified environment for enhanced plant growth and health still remains. Keywords Panax ginseng, Panax quinquefolium, cultivation, ginseng production.

Objective : We have reviewed the potential cancer preventive and other relevant properties of Panax ginseng C. A. Meyer, which has been traditionally used as a natural tonic in oriental countries. Data identification and study selection: Publications on Panax ginseng and its relation to cancer were obtained from the Medline database (1983-2000) and by checking reference lists to find earlier reports. The reports cover experimental models and human studies on cancer-preventive activity, carcinogenicity and other beneficial or adverse effects. In addition, possible mechanisms of chemoprevention by ginseng were also considered. Results : Published results from a cohort and two case-control studies in Korea suggest that the intake of ginseng may reduce the risk of several types of cancer. When ginseng was tested in animal models, a reduction in cancer incidence and multiplicity at various sites was noted. Panax ginseng and its chemical constituents have been tested for their inhibiting effect on putative carcinogenesis mechanisms (e.g., cell proliferation and apoptosis, immunosurveillance, angiogenesis); in most experiments inhibitory effects were found. Conclusion : While Panax ginseng C. A. Meyer has shown cancer preventive effects both in experimental models and in epidemiological studies, the evidence is currently not conclusive as to its cancer-preventive activity in humans. The available evidence warrants further research into the possible role of ginseng in the prevention of human cancer and carcinogenesis.

Lipid and fatty acid compositions of the free lipids in Panax ginseng (Korea, Japan and China), Panax quinquefolium (America, Canada) and Panax notoginseng (China) were studied by means of silicic acid column chromatography, thin-layer chromatography and gas-liquid chromatography. Free lipid contents were 1.13 to 1.24% in panax ginseng and 0.87 to 1.18% in Panax quinquefolium and 0.39% in panax notoginseng. Neutral lipid fractions were 81.2 to 84.4%, while glycolipid fractions 8.01% to 14.47% and phospholipid fractions 3.49 to 5.74% in free lipid contents. The major components were triglycerides, free sterols, diglyceride, free fatty acids and sterol esters in neutral lipid fractions, sterol glucoside, monogalactosyl diglyceride, digalactosyl diglyceride, esterified steryl glucoside in glycolipid fractions and phosphatidyl glycerol, phosphatide, ethanolamine, phosphatidyl choline in phospholipid fractions. The contents and compositions of neutral lipids and glyclipids were some different among various ginsengs, whereas phospholipids showed relatively similar compositions in the contents. Seventeen fatty acids were analyzed in the four free lipid fractions from the various ginsengs and the main fatty acids were linoleic acid, palmitic acid, oleic acid and linolenic acid. It was found that the amounts of some fatty acids were different among the various ginsengs, but the fatty acid patterns of these ginsengs were on the whole similar.

Our country has been produced much amounts of panax ginseng roots which has a stimulating effects on the metabolism of protein, lipid and nucleic acids in the body. And the leaf trunk of panax ginseng were also produced a considerable amounts as the by - products. Therefore, this study was devised to observe the nutritional effect to rats feeding of rice diet supplemented with by - products of panax ginseng, male Albino rats of pure strain weighing 73.8 ${\pm}$ 0.7 g were used as experimental animal to investigate the changes of cholesterol in heart and testis. The animals were divided into sixteen diet group, they were the protein contents of 9%, 12%, 15% and 18% supplemented with 2% panax ginseng roots and its by - products respectively. The group without the supplements were used as the control. The diet group were again divided into 2 groups according to the feeding terms, 4 weeks and 8 weeks. It is concluded that the free from cholesterol and total cholesterol contents in the heart and testis with the supplements of panax ginseng roots and its by - products showed significant difference compared to the control group.

We have studied the effect of ouabain, tool ginseng saponin, panax saponin C (protopanaxatriol derivative) and ginsenoside $Rb_{1}$ (protopanaxadiol derivative) on $Na^+,K^+$-ATPase and $Mg^{++}$-ATPase activities were determined by the method of Robinson and ATPase activities were determined by the method of King. The $Na^+,K^+$-ATPase activities were inhibitied by 90.1% and 51.1% respectively at the concentration of $10^{-3}M$ and $10^{-4}M$ ouabain. The results are consistent with those of Robinson. The $Na^+,K^+$-ATPase activities were increased by 14.3% and 10.0% respectively at the concentration of $10^{-4}$g/ml and $10^{-5}$g/ml total ginseng saponin. Panax saponin C obtained by the method of Han and ginsenoside $Rb_{1}$ obtained by the method of Shibata were used. The $Na^+,K^+$-ATPase activities were increased in the presence of panax saponin C and the increased activity with panax saponin C was greater than that with total ginseng saponin. On the other hand ginsenoside $Rb_{1}$ showed an inhibitory effect on $Na^+,K^+$-ATPase. Total ginseng saponin, panax saponin C and ginsenoside $Rb_{1}$ had no effect on $Mg^{++}$-ATPase. Therefore, it may be concluded that total ginseng saponin has dual effects on microsomal $Na^+,K^+$-ATPase, that is, panax saponin C exhibits stimulatory action, whereas ginsenoside $Rb_{1}$ shows inhibitory action.

Panax ginseng leaves are produced as the by-product when Panax ginseng roots were harvested. The Panax ginseng leaves was examed for the applicable possibility as the functional food. In this study, the changes in chemical composition of Panax ginseng leaves was examed by three methods as the hot-air dried(DRT), the aged tea(AGT) and the heat processed tea(HPT). The general composition of Panax ginseng leaves tea was shown as similar results in 3 different process methods. The level of the crude lipid and reducing sugar concentration were decreased slightly in HPT. The free sugar content of DRT was higher than the HPT and AGT. The existence of the higher content of free sugar composition in order are sucrose, fructose and glucose. The concentration of serine was the highest in the free amino acids, which were shown from 309.6 mg% to 336.6 mg%. The contents of free amino acid in Panax ginseng leaves made by DRT was higher than by AGT and HPT. The concentration of Ca was shown as the highest content among the minerals and was 2,115 mg%. The contents of minerals were existed in order of Ca, K, Mg, P, Na, Mn, Fe, Zn and Cu. But there were hardly any remarkable differences of mineral concentrations of Panax ginseng leaves tea made by different processing methods. The concentration of water soluble solid of Panax ginseng leaves tea processed by HPT was higher than by DRT and AGT. The concentration of ascorbic acid was shown the highest value of 424.4mg% in HPT. There was no differences in the fatty acid composition according to their processing methods. The concentration of palmitic acid was higher than that of other fatty acid. The order of fatty acid concentration were palmitic aicd, linoleic acid, linolenic acid, oleic acid and stearic acid, abundantly. As a conclusion, HPT was shown as the best process method for the production of Panax ginseng leaves tea.
