Background: Red ginseng contains components, including microelements, vitamins, essential oils, and fatty acids, that can be used in skincare to delay the aging process. We investigated the effects of red ginseng treatment on skin elasticity by assessing cellular stiffness and measuring collagen protein synthesis. Methods: Human dermal fibroblasts were treated with red ginseng, and the resulting changes in stiffness were investigated using atomic force microscopy. Cytoskeletal changes and mRNA expression of biomarkers of aging, including that of procollagens I and VII, elastin, and fibrillin-1, were investigated. Collagen in a human skin equivalent treated with red ginseng was visualized via hematoxylin and eosin staining, scanning electron microscopy, and atomic force microscopy. Results and conclusion: The stiffness of fibroblasts was significantly reduced by treatment with red ginseng concentrations of ≥ 0.8 mg/mL. The ratio of F-actin to G-actin decreased after treatment, which corresponded to a change in fibroblast stiffness. The storage modulus (G') and loss modulus (G'') of the skin equivalent were both lowered by red ginseng treatment. This result indicates that the viscoelasticity of the skin equivalent can be restored by red ginseng treatment.

Effect of red ginseng treatment on experimentally induced hyperkeratosis was investigated by light microscopic observation scanning electron microxcope (SEM) examination, epidermal enzyme activities nd lipid contents. Both light microscopic observation and SEM examination showed that hexadecane induced epidermal hyperplasia, hypertrophy and hyperkeratosis by increasing the numbers as well as the sizes of epidermal cells including desquamating horny cells. The superficial horny cells were protruded around the base of hair shaft. Among red ginseng components, only saponin treatment inhibited epidermal hyperplasia and hyperkeratosis by reducing the thickness of epidermis and arranging the cornified cells. Saponin from korean red ginseng inhibited abnormally increased epidermal LDH, ICD and G6PDH activities and reduced the contents of epidermal lipids induced by hexadecane. It seems that red ginseng saponin has preventive effect on experimental hyperkeratosis possibly by controlling the enzyme activities involved in epidermal cellular metabolism, resulting in reduced amounts of abnormal epidermal lipids.

Total saponins and ether extracts of red and white ginseng were obtained and their effects on blood pressure in cat and their histamine liberating activities in rabbits were measured. 1) Ether extract of red ginseng showed a transient hypotensive effect and subsequently showed a remarkable and persistent hypotensive effect, whereas other three fractions, such as saponin fractions of red and white ginseng and ether extract of white ginseng showed only a initial transient hypotensive effects. 2) Histamine levels liberated into blood after administration of each fractions measured by the bioassay with guinea pig ileum. Ether extract of red ginseng immediately increased histamine contents in plasma but the histamine levels decreased to normal level within 10min in spite of decreased blood pressure was sustained. Although white ginseng saponin lowered blood pressure immediately when it is administered, histamine release was observed after 10min. The results suggest that hypotensive effects of ginseng seems to have no correlation with the histamine liberating activity. Ginseng appears to show hypotensive effect via some other mechanisms.

As a part of our ongoing effort to develop new antineoplastic immunostimulator from natural sources, bioassay-directed fractionationn of polysaccharides from Korean red ginseng was carried out by observing the proliferation of marine spleen cells and the generation of lymphoklne activated killer (LAK) cells. The acidic polysaccharide fractions proliferated spleen cells and generated LAK cells in proportion to their acidity in vitro. The LAK cell which was induced by ginseng showed tumoricidal activity against both NK celt sensitive and insensitive tumor target cells without major histocompatibility (MHC) restriction. Adherent macrophages and CD4+helper T cells were involved in the generation of the LAK cells. The acidic polysaccharide from Korean red ginseng synerglzed with recombinant IL-2 (rIff-2) at lower than 3 U/ml. The optimal doses of the acidic polysaccharide from Korean red ginseng for the proliferation of spleen cells and for the generation of LAK cells were 1 mg/ml and 100 $\mu\textrm{g}$/ml, respectively; this means that the mechanisms for the both activities may be different from each other.

Objectives : The purpose of this experiment is comparing the difference on natural killer cell activity through Korean red ginseng and Chinese red ginseng by $^{51}Cr$ release assay. Methods : Thirty rats were equally divided into a Korean red ginseng group, a Chinese red ginseng group and a control group. Korean and Chinese red ginseng were administrated to the rats at 200mg daily for a weak, while 0.9% normal saline was given to the control. Percent specific lysis (PSL) and lytic units (LU) were calculated from spleen cells by $^{51}Cr$ release assay. Results : Percent specific lysis of the Korean red ginseng group was significantly higher than that of the control in the ratio of 100:1, effector cell:target cell (p<0.05). Percent specific lysis of Korean red ginseng group was also significantly higher than that of the Chinese red ginseng group in the ratio of 25:1, effector cell:target cell (p<0.05). Chinese red ginseng showed no effect on NK cell activity. Conclusions : These findings suggest that Korean red ginseng improves immunologic function and shows superior effects than Chinese red ginseng.

Although widely applied in the food industry, extrusion cooking has not been applied to the traditional red ginseng process for steaming and drying ginseng. We therefore investigated the change in the effective components in red ginseng (total saponins, ginsenosides and maltol) from extruded raw ginseng. The variables were the drying temperature of the sliced raw ginseng (80 and $90^{\circ}C$) before the extrusion process and the moisture content (15 and 22%, w.b.) during the extrusion process. Ginsenosides Rg1 and Rg2 were detected in dried ginseng at $80^{\circ}C$, but ginsenoside Rg3, which was contained in red ginseng, was not detected. On the other hand, ginsenosides Rg1, Rg2 and Rg3 were detected in extruded ginseng at moisture contents of 15 and 22%. Total ginsenosides were highest at $90^{\circ}C$ drying temperature and 22% moisture content for the extrusion process.

For quality control of components in Korean red ginseng powder and extract, a new method for simultaneous quantification of 12 ginsenosides ($Rg_1$, Re, Rf, $Rh_1$, $Rg_2$[S], $Rg_2$[R], $Rb_1$, Rc, $Rb_2$, Rd, $Rg_3$[S], and $Rg_3$[R]) was studied. Compared to the official method for quantification of marker substances (ginsenosides $Rg_1$ and $Rb_1$), the proposed methods were guaranteed by in-house method validation. Several criteria such as linearity, specificity, precision and accuracy were evaluated. For red ginseng powder, recovery (averaging 95% to 105%) was calculated, and analysis of variance was carried out to estimate the relative standard deviation (0.20% to 2.12%). For red ginseng extract, the average recovery rate was 90% to 99% and the relative standard deviation was 0.39% to 2.40%. These results indicate that the proposed method could be used in the laboratory for determination of 12 ginsenosides in red ginseng powder and extract. In addition, this method was found to be suitable for quality control of ginseng products and potentially offer time and cost benefits.

Background: Ginseng (Panax ginseng) is a widely used traditional herbal supplement that possesses various health-enhancing efficacies. Various ginseng products are available in market, especially in the Korean peninsula, in the form of drinks, tablets, and capsules. The different ginseng types include the traditional red ginseng extract (RGE), white ginseng, and black red ginseng extract (BRGE). Their fermented and enzyme-treated products are also available. Different treatment regimens alter the bioavailability of certain compounds present in the respective ginseng extracts. Therefore, in this study, we aimed to compare the antioxidant and immune-stimulating activities of RGE, BRGE, and fermented red ginseng extract (FRGE). Methods: We used an acetaminophen-induced oxidative stress model for investigating the reduction of oxidative stress by RGE, BRGE, and FRGE in Sprague Dawley rats. A cyclophosphamide-induced immunosuppression model was used to evaluate the immune-stimulating activities of these ginseng extracts in BALB/c mice. Results: Our results showed that most prominently, RGE (in almost all experiments) exhibited excellent antioxidant effects via increasing superoxide dismutase, catalase, and glutathione peroxidase activities in the liver and decreasing serum 8-hydroxy-2'-deoxyguanosine, aspartate aminotransferase, and lactate dehydrogenase levels compared with the groups treated with FRGE and BRGE. Moreover, RGE significantly increased the number of white blood cells, especially T and B lymphocytes, and antibody-forming cells in the spleen and thymus, and it also activated a number of immune cell subtypes. Conclusion: Taken together, these results indicate that RGE is the best supplement for consumption in everyday life for overall health-enhancing properties.

인삼(Panax ginseng C.A. Meyer)은 가공방법fl 따라 크게 백삼과 홍삼으로 분류된다. 가공 공정 면에서 홍삼은 생 인삼(수삼)을 그대로 건조한 백삼과는 다르게 일정한 온도조건 하에서 수증기로 쪄서 건조 한 인삼으로 두 종류의 인삼간에는 열처리 공정에 차이점이 있다. 품질 안정성 면에서 홍삼은 열처리과정에서 효소의 불 활성화와 자체 항산화 물질의 증가로 저장성이 양호하고, 호화전분이 되어 끓일 때 내용성분이 잘 우러나오고 소화 흡수도 양호한 것으로 여겨진다. 성분 면에서 홍삼제조 시 열처리(steaming처리)와 가수분해 반응에 의해 화학성분의 구조적 변환이 일어나 홍삼특유의 암세포증식억제 활성 성분인 $ginsenosides-Rh_2,\;-Rh_4,\;-Rs_3,\;-Rs_4,\;-Rg_5$, 암세포 전이 억제 및 혈관확장 효과 등을 나타내는 $ginsenoside-Rg_3$ 등이 생성된다는 것이 밝혀졌다. 또한 비사포닌계 생리활성물질로 암세포 증식억제 활성을 가진 polyacetylenic alcobol의 구조적 변환에 의해 panaxytriol 등이 생성되고, 그리고 maillard 반응 생성물로 항산화 활성 성분인 maltol과 당과 아미노산이 결합된 아미노산 유도체인 arginyl-fructsyl-glucose등이 생성된다. 한편 홍삼과 백삼 및 이들 제품의 수출과 관련하여 각 수출 대상국의 진세노사이드 수준의 품질관리기준에 대한 충분한 분석화학적 정보의 확보가 필요하며, 금후 이에 적합한 품질기준의 설정 보완이 필요할 것이다. 특히 홍삼의 경우 찌는 온도와 시간의 장단에 따라, 또는 그 농축액 제조 시 추출 및 농축 조건(온도와 시간)에 따라 인삼의 품질 지표 성분으로 이용되고 있는 ginsenosides를 비롯한 상당한 성분의 변환이 일어날 수 있으므로 이를 고려한 품질관리방법의 고안이 필요할 것으로 사료된다. 효능 면에서 홍삼과 백삼의 차별성에 대해서는 in vitro 혹은 in vivo 시험에서 노화억제효과와 관련된 항산화 활성을 비롯해서 혈액순환개선 효과, 암 발생 억제력 등의 약리 활성이 홍삼이 백삼보다 상대적으로 우수한 것으로 보고되었다. 아울러 한방의학에서 일반적으로 허를 보 하는 힘은 홍삼이 강한 것으로 인식되고 있다. 그러나 아직 실제 임상실험에 의한 비교 평가는 미흡한 실정이며, 특히 경구투여 후 체내 동태측면에서 그 효과의 차별성에 대한 연구는 거의 이루어지지 않았다. 금후 홍삼과 백삼의 효과 우열의 측면이 아닌 그 용도와 적응증에 차이가 있는지에 초점을 맞추어 보다 과학적 평가가 이루어져야 할 것이다. 결론적으로 가능한 동일한 재배조건에서 생산된 원료수삼으로 제조된 홍삼과 백삼의 원 생약과 그 추출 분획물, 또는 성분을 시료로 하여 화학성분 조성을 비교하고 이와 연계한 실험적 효능연구의 확충과 특히 임상적 효능 비교연구를 통해 과연 그 적응증에 차이가 있는지에 대한 보다 많은 과학적 검토가 이루어져야 할 것이다.
