In recent years, several therapeutic drugs have been rationally designed and synthesized based on the novel knowledge gained from investigating the actions of biologically active chemicals derived from foods, plants, and medicinal herbs. One of the major advantages of these naturalistic chemicals is their ability to interact with multiple targets in the body resulting in a combined beneficial effect. Ginseng is a perennial herb (Araliaceae family), a species within the genus Panax, and a highly valued and popular medicinal plant. Evidence for the medicinal and health benefits of Panax ginseng and its components in preventing neurodegeneration has increased significantly in the past decade. The beneficial effects of P. ginseng on neurodegenerative diseases have been attributed primarily to the antioxidative and immunomodulatory activities of its ginsenoside components. Mechanistic studies on the neuroprotective effects of ginsenosides revealed that they act not only as antioxidants but also as modulators of intracellular neuronal signaling and metabolism, cell survival/death genes, and mitochondrial function. The goal of the present paper is to provide a brief review of recent knowledge and developments concerning the beneficial effects as well as the mechanism of action of P. ginseng and its components in the treatment and prevention of neurodegenerative diseases.

Traditionally, Asian ginseng or Korean ginseng, Panax ginseng has long been used in Korea and China to treat various diseases. The main active components of Panax ginseng is ginsenoside, which is known to have various pharmacological treatment effects such as antioxidant, vascular easing, anti-allergic, anti-inflammatory, anti-diabetes, and anticancer. Most reactive oxygen species (ROS) cause chronic diseases such as myocardial symptoms and cause fatal oxidative damage to cell membrane lipids and proteins. Therefore, many studies that inhibit the production of oxidative stress have been conducted in various fields of physiology, pathophysiology, medicine and health, and disease. Recently, ginseng or ginsenosides have been known to act as antioxidants in vitro and in vivo results, which have a beneficial effect on preventing cardiovascular disease. The current review aims to provide mechanisms and inform precious information on the effects of ginseng and ginsenosides on the prevention of oxidative stress and cardiovascular disease in animals and clinical trials.

Systematic electrophoretic analysis of alcohol-soluble proteins and salt-soluble proteins of 247 Panax ginseng (P.g) and Panax quinquefolium (P.q) germplasms seed was carried out on an improved lactate-polyacrylamide gel electrophoresis, a method with high resolving power, good reproducibility and stability. The electrophoregrams of proteins, according to their migration rate, were classified into four groups such as ${\alpha}$, ${\beta}$, ${\gamma}$ and $\omega$ for the alcohol-soluble proteins and three such as I, II and III for the salt-soluble ones. Panax ginseng or Panax quinquefolium had their own unique band pattern distinguishable from each other, regarding as their specific "fingerprint". In this study, 3 of 168 (1.8%) P.g germplasms and 1 of 79 (1.3%) P.q germplasms had their own unique band pattern, showing that P.g and P.q germplasms have poor genetic diversity in species. The band patterns of dry seed and stratified seed (embryo rate=60%) were basically the same. The band number of the F, hybrid of p.gx p.q was exactly equivalent to the number of the common bands plus the specific bands of the two parents, indicating that the difference of band patterns was a genetic trait con- trolled by the nuclear genes. The electrophoregram of F1 of P.g x P.q could be predicted by that of the two parents and the band pattern of the F1 hybrids could be demnonstrated by that of the mixed seed extract from the two parents.

Free amino acid (FAA) compositions in the central part (pith-xylem : P-X) and the outer part (phloem-cortex : P-C) of root were investigated for P ginseng (P.g), p. quinque-folium (P.q) an, B P nutoginsen (P.n) by an amino acid analyzer. Total free amlno acids content (TFAA) was highest in p.맥 and lowest in p.n. The TFAA of P-Xs were higher than those of P-Cs in these Panax species except p.n. The higher the TFAA in P-X, the higher the ratio of TFAA in P-X to that in P-C. Seven- teen free amino acids and ammonia were identified, and four unknown peaks appeared before the usual amino acids eluted. The total aspartic acid equivalent of these unknown peaks was corresponded to 77% of known TFAA in P-C of p.n, 17% in P. n, and 7% in p.q. The pattern of unknown peaks of p.g was different from p.q and similar to P.n. In all samples six major amino acids and ammonia accounted for 90~95% of TFAA. Arginine was comprised from 29% (P.n) to 43% (P.g) by amole as amino acid and from 50 to 71% by amole as nitrogen (N amole) in TFAA. Ammonia was the second abundant one by amole and the third by Npmole. Histidine was the second by Npmole. Praline was one of major FAA in p.q. Pattern similarity of FAA composition (excluding Arg and Am) by simple correlation was closer between P-C of p.g and P-X of p.q than between both P-Xs and quite different between the P-X of p.g and that of p.n. The pattern similarities of major FAA percent abundance excluding Arg and Am were significant only between P-X and P-C of the same species. Arginine content (amole) had positive correlation (r=0.859, p=0.05) with Arg/Am among species. Ammonia content was higher than arginine in p.n. Tryptophan content was greatest in p.n among species and higher than lysine only in p.n. The ratios of TFAA to N(W/W) were in the range of 3.89~4.14 for TFAA and 3.61~3.92 for TFAA plus ammonia.

아바스큘라 내생균근(arbuscular mycorrhizae, AM) 균은 대부분의 육상식물 뿌리와 공생하며, 식물의 성장에 도움을 주는 균이다. 인삼은 다년생 식물로서 뿌리를 약재로 사용하는 대표적인 약재 중 하나이다. 본 연구에서는 우리나라 8개 지역에서 인삼을 채집하여 AM 균을 염색을 통하여 형태적으로 관찰하고, 분자생물학적인 방법을 사용하여 뿌리내에 공생하는 다양한 AM 균을 확인하였다. 인삼의 뿌리에 감염되어 있는 AM 균을 염색하여 형태적으로 관찰한 결과 감염률이 낮고 흐리게 염색되었다. 또한 균사와 vesicle 이 발견되었고 이들은 Arum type 으로 판단되지만 arbuscule을 관찰하지 못했기 때문에 Arum-type으로 단정하기는 어려웠다. 식물 내에 공생하는 AM균들의 종류를 확인하기 위하여 채집된 인삼의 뿌리에서 내생균근 균의 DNA를 AM균에 특이적인 18s rDNA primer를 이용한 nested PCR을 수행하여 AM 균의 18S rDNA중 일부를 확보하였다. 증폭된 DNA는 클로닝을 통해서 개별 내생균근 균 종의 염기서열들로 분리하였고, 이들은 AluI, HinfI과 같은 제한 효소를 사용하여 RELP하였다. RELP 패턴에 따라 그룹을 나누어, 각 그룹에서 1개씩 염기서열 분석을 수행하였다. 염기서열은 기존의 서열과의 유사성과 계통 관계의 분석을 통하여 모두 AM균인 것으로 확인되었고, 다음 2개의 종과 가장 유사한 것으로 판단되었다; Paraglomus brasilianum, Glomus spurcum이 중 Paraglomus에 속하는 종인 P. brasil-ianum. 이 인삼의 뿌리에서 공통적으로 관찰되어 이들 균과 인삼과의 특이적 관계에 관하여 추측할 수 있었고, G. spurcum은 유사한 것으로 분석된 염기서열들이 계통도 상에서 특이한 분지를 형성하는 것으로 나타났는데, 이들 분지에 대해서는 확충된 염기서열들과 비교 분석과 같은 연구가 필요한 것으로 생각된다.

Background: The use of X-ray phase-contrast microtomography for the investigation of Chinese medicinal materials is advantageous for its nondestructive, in situ, and three-dimensional quantitative imaging properties. Methods: The X-ray phase-contrast microtomography quantitative imaging method was used to investigate the microstructure of ginseng, and the phase-retrieval method is also employed to process the experimental data. Four different ginseng samples were collected and investigated; these were classified according to their species, production area, and sample growth pattern. Results: The quantitative internal characteristic microstructures of ginseng were extracted successfully. The size and position distributions of the calcium oxalate cluster crystals (COCCs), important secondary metabolites that accumulate in ginseng, are revealed by the three-dimensional quantitative imaging method. The volume and amount of the COCCs in different species of the ginseng are obtained by a quantitative analysis of the three-dimensional microstructures, which shows obvious difference among the four species of ginseng. Conclusion: This study is the first to provide evidence of the distribution characteristics of COCCs to identify four types of ginseng, with regard to species authentication and age identification, by X-ray phase-contrast microtomography quantitative imaging. This method is also expected to reveal important relationships between COCCs and the occurrence of the effective medicinal components of ginseng.
