Results of karyological study of intact plants and some callus lines of Panax ginseng are presented. In the native plants of P. ginseng the nucleus with 1 nucleolus (90%) dominate, and nucleus with 2 nucleoli is rare. One nucleolar nucleus also dominate in interphase nuclei of cells of cultivated P. ginseng (from 2006), but we also found nucleus with 2 to 3 nucleoli in the same cell lines. Interphase nuclei of P. ginseng in long cultivated lines (from 1988) contain 1 to 9 nucleoli, with a predominance of nuclei containing from 3 to 4 nucleoli. It was shown that long-time cells (cultivated since 1988) had cytogenetic changes such as increase level of polyploid and aneuploid cells, increase of nucleoli number into interphase nucleus and decrease of nuclei/nucleoli ratio. These long-time cultivated cells had very low ginsenoside content.

Agmatine iminohydrolase (EC 3.5.3.12) catalyzes the hydrolysis of agmatine into putrescine. The enzyme seems to be one of the critical enzymes in putrescine biosynthesis. The enzyme was purified to homogeneity from Panax ginseng C.A. Meyer by combined method of ammonium sulfate 1 fractionation, DEAR anion exchange column, hydroxyapatite column and agmatine carboxyhexyl Sepharose 4B affinity column. The molecular weight estimated by native pore gadient polyacrylamide gel electrophoresis was 71, 000 Dalton, while that estimated by SDS-PAGE was 70, 000 Dalton, indicating a monomeric enzyme. The optimal pH and temperature were 9.0 and 37$^{\circ}C$, respectively. The Km and 1 Vmax for agmatine were 8.3 mM and 14.4 nmole/hr, respectively. Heat stability of this enzyme was high. The enzyme was observed to be inhibited by polyamines such as putrescine, cadaverine, spermidine and spermine. Especially, putrescine was a potent inhibitor of the purified enzyme. These results suggest that polyamines could be important in growth regulation of Panax ginseng C.A. Meyer.

Ginseng, a Korean native herb, has been a symbol of mystic cure-all which provides longevity benefits throughout Korean history. According to Chinese historical records, a major source of wild ginseng has been described as Korean peninsula, which is the most suitable ginseng production area, and the Manchu region near Mt. Baekdu and the Maritime Province. Since Tang dynasty period (618-917 CE), Chinese has also called ginseng as "Goryeo Ginseng", which is named after "Goguryeo" (37 BCE-668 CE), an ancient kingdom of Korea, from which they mainly imported the herb as the region was famous for its high quality of ginseng. To date, it refers to Korean ginseng. This study compares the medicinal properties of ginseng as stated in the ancient Korean medical books with the major Korean historical records regarding the usage of ginseng and its symbolism of longevity in everyday life. By contrasting these findings, we tried to figure out how the actual medicinal properties of ginseng and the anticipation of longevity are related. It was confirmed that the expectations about longevity were widely applied to everyday life. In addition, the study investigates the various usage of ginseng as a motive for decorative patterns and as an ingredient for daily products including snacks, health drinks, various types of food, clothing patterns, and so on. Finally, the usage of ginseng ingredients in the cosmetic products fulfilled the desire of Korean people to purchase, showing the aesthetic recognition and medicinal understandings about the herb. These findings suggest that ginseng is an important medicinal agent that not only symbolizes longevity and good health but also has a great influence on the lives of Koreans.

Background: Peptides have diverse and important physiological roles in plants and are ideal markers for species identification. It is unclear whether there are specific peptides in Panax quinquefolius L. (PQ). The aims of this study were to identify Quinetides, a series of diverse posttranslational modified native peptides of the ribonuclease-like storage protein (ginseng major protein), from PQ to explore novel peptide markers and develop a new method to distinguish PQ from Panax ginseng. Methods: We used different fragmentation modes in the LTQ Orbitrap analysis to identify the enriched Quinetide targets of PQ, and we discovered Quinetide markers of PQ and P. ginseng using ultrahigh-performance liquid chromatography-quadrupole time-of-flight mass spectrometry analysis. These "peptide markers" were validated by simultaneously monitoring Rf and F11 as standard ginsenosides. Results: We discovered 100 Quinetides of PQ with various post-translational modifications (PTMs), including a series of glycopeptides, all of which originated from the protein ginseng major protein. We effectively distinguished PQ from P. ginseng using new "peptide markers." Four unique peptides (Quinetides TP6 and TP7 as markers of PQ and Quinetides TP8 and TP9 as markers of P. ginseng) and their associated glycosylation products were discovered in PQ and P. ginseng. Conclusion: We provide specific information on PQ peptides and propose the clinical application of peptide markers to distinguish PQ from P. ginseng.

This study was conducted to investigate growth characteristics to develop the technique to select resistant cultivar by wet injury at an early stage through the automatic irrigation maintaining 30, 20, 10 kPa respectively using native variety, Chunpoong, Yunpoong, Gumpoong and Sunun. The aerial growth was decreased at 10 kPa compared to 30 kPa. In addition, the survival rate was decreased by 66.6%, 62.3%, 33.8% at 30, 20, 10 kPa, respectively. The survival rate of Chunpoong and Gumpoong were higher than others at 10 kPa. While root growth characteristics such as root length, root weight, number of lateral root and side root were tended to decrease, root diam was no significant or increased. And the more humid condition is, the more the incidence rate of rusty root and rough skin were tended to increase. The epidermal thickness of Chunpoong and Gumpoong was increased but the figures of native variety, Yunpoong and Sunun were decreased at 10 kPa compared to 30 kPa. But, the tissue stiffness of root was decreased at 10 kPa compared to 30 kPa.

Ginseng has been recognized as a lifespan extending medicine which has been regarded as one of the medicines classified as top medicines, as the Boncho (medical herbs) study which is influenced by the idea of guidance's costume and food concept mainly in China is gaining its bona fide form. As the demand for ginseng has been expanded to other levels, the demand for ginseng has been increasing. Ginseng from the nature reached its supply chain limit due to its extinction and difficulty of picking, so it translated into ginseng cultivation of economy rather than harvesting in nature. After the start of ginseng cultivation, the ginseng cultivation was further enhanced by the rapid development of processing methods such as white-ginseng and red-ginseng, and the surge of consumption due to the traditional belief in ginseng drug efficacy and support of scientific research. In the Joseon Dynasty, the name Gasam (cultivated ginseng) had been created as ginseng was cultivated on farmland after the stage of SanYang (wild cultivated ginseng), the purpose of the new name Gasam is to differentiate from natural ginseng, and natural ginseng lost its firm position as the genuine ginseng as the Gasam replaced the genuine ginseng, and the natural ginseng got a new name of SanSam (wild ginseng). Because the real ginseng substance concept dissipated, and as Gasam is being called ginseng, the name Gasam was also disappeared. As a result, it was possible to grow large quantities according to the arrival of the Gasam era, and it was possible to supply the demand for ginseng, and it could become one agricultural industry. In this ginseng cultivation, in Japan where ginseng did not grow naturally, it was difficult to obtain ginseng from Joseon and faced with a shortage of ginseng at all times. Therefore, the shogun cultivated the Gasam systematically at the national level by the inside of the shogunate. However, since the natural ginseng is native to China and Korea, there is a concern about the deterioration of the quality of natural ginseng due to the incorporation of cultivated ginseng (Gasam). To protect the interests, the cultivation of ginseng was subject to control. For this reason, the lack of historical information on Gasam cultivation, which had to be started secretly, would be a natural result. In this paper, althouh not sufficient enough, the historical informations were used to summarize the history of ginseng cultivation in China, Japan and Korea.

Panax ginseng (family- Araliaceae) is a native plant of Korea and has been used for past several years among oriental people. To evaluate the radioprotective potential of P. ginseng on the formation of giant cells in the testis of Swiss albino mice, the animals were divided into four groups: -(I)-Only vehicle was administered. (II)P. ginseng treated group: -The animals received 10 mg/kg body weight P. ginseng root extract (in DDW) i.p. continuously for 30 days. (III) Irradiated group: -The animals were exposed to 8 Gy gamma radiation at the dose rate of 1.69 Gy/min at the distance of 80 ems. (IV) Combined treatment group: -Animals were given P. ginseng extract for four days and on fourth day they were irradiated to 8 Gy gamma radiation after 30 minute of extract administration. The animals of these three groups were autopsied on day 1,3, 7, 14 and 30 days. In ginseng treated group, active spermatogenesis was observed without any toxic effect. Histopathological studies of irradiated group (II) revealed reduction in germ cell count, loss of sperms and formation of multinucleated giant cells on day 7th. These giant cells were formed by round nuclei of early or late spermatids. In combination group (III), although germinal epithelium was still disorganized with loss of cells in few tubules, but no giant cell formation was observed. In order to know the mechanism of radioprotection of ginseng, LPO and GSH were estimated. It was observed that pretreated irradiated animals showed inhibition of LPO and increase in GSH. Thus the present study suggests ginseng protects male gonads. This may be attributed to the inhibition of LPO and increase synthesis of GSH byginseng.

To selection of optimal shading material, two-year-old ginseng (Panax ginseng C. A. Meyer) of new cultivar, 'Cheonpoong' (CP), and native species 'Hwangsookjong' (HS) were cultured under three kinds of shading materials such as three-layered blue and a one-layered black PE (polyethylene) net (TBSB), blue PE sheet (BS), and aluminium coated PE sheet (AS) in imperfectly drained paddy soil. Growth characteristics, yield and ginsenoside contents were investigated under three shading materials. Yield and ginsenoside contents of ginseng were distinctly affected by intensity and quality of sunlight penetrated through shading materials. Light transmission ratio, air and soil temperature according to shading materials were higher in order of BS, AS, and TBSB. However, ratio of aerial phase and porosity of the soil were higher in order of AS, BS, and TBSB, respectively. There was no significantly difference in the ratio of rusty colored root by shading materials. CP showed higher stem length, leaf area, and root weight than that of HS, while the former showed distinctly lower discolored leaf ratio than that the other. Eight kinds of ginsenosides content of CP were higher than that of HS in $Rg_1$, Re, Rf, $Rb_1$ and Rc except $Rg_2$, $Rb_2$, and $Rb_3$. Total ginsenoside contents of CP was distinctly higher than that of HS. Total ginsenoside contents as affected by shading materials was higher in order of BS, TBSB, and AS in CP, while TBSB, BS, and AS in HS.
