This study was performed to enhance contents of low molecular ginsenoside using steaming and fermentation process in low quality fresh ginseng. For increase in contents of Rg2, Rg3, Rh2 and CK in low quality fresh ginseng, a steaming process was applied at $90^{\circ}C$ for 12 hr which was followed by fermentation process at Lactobacillus rhamnosus HK-9 incubated at $36^{\circ}C$ for 72 h. The contents of ginsenoside Rg1, Rb1, Rc, Re and Rd were decreased with the steaming associated with fermentation process but ginsenoside Rg2, Rg3, Rh2 and CK increased after process. It was found that under the steaming associated with fermentation process, low molecule ginsenosides such as Rg2, Rg3, Rh2 and CK were increased as 3.231 mg/g, 2.585 mg/g and 1.955 m/g and 2.478 mg/g, respectively. In addition, concentration of benzo[${\alpha}$]pyrene in extracts of the low quality fresh ginseng treated by the complex process was 0.11 ppm but it was 0.22 ppm when it was treated with the steaming process. This result could be caused by that the most efficiently breakdown of 1,2-glucoside and 1,4-glucoside linkage to backbone of ginsenosides by steaming associated with fermentation process. This results indicate that steaming process and fermenration process can increase in contents of Rg2, Rg3, Rh2 and CK in low quality fresh ginseng.

Background: Ginseng total saponin (GTS) contains various ginsenosides. These ginsenosides are widely used for treating cardiovascular diseases in Asian communities. The aim of this study was to study the effects of GTS on cardiac injury after global ischemia and reperfusion (I/R) in isolated guinea pig hearts. Methods: Animals were subjected to normothermic ischemia for 60 minutes, followed by 120 minutes of reperfusion. GTS significantly increased aortic flow, coronary flow, and cardiac output. Moreover, GTS significantly increased left ventricular systolic pressure and the maximal rate of contraction ($+dP/dt_{max}$) and relaxation ($-dP/dt_{max}$). In addition, GTS has been shown to ameliorate electrocardiographic changes such as the QRS complex, QT interval, and RR interval. Results: GTS significantly suppressed the biochemical parameters (i.e., lactate dehydrogenase, creatine kinase-MB fraction, and cardiac troponin I levels) and normalized the oxidative stress markers (i.e., malondialdehyde, glutathione, and nitrite). In addition, GTS also markedly inhibits the expression of interleukin-$1{\beta}$ (IL-$1{\beta}$), IL-6, and nuclear factor-${\kappa}B$, and improves the expression of IL-10 in cardiac tissue. Conclusion: These data indicate that GTS mitigates myocardial damage by modulating the biochemical and oxidative stress related to cardiac I/R injury.

인삼(Panax ginseng C.A. Meyer) 종자의 개갑 직후로부터 발아 직전까지의 후숙과정에 있어서 저장물질의 분해와 연관된 배유의 미세구조 변화상을 광학 및 전자현미경을 이용하여 규명하였다. 종자의 후숙단계에서는 제형층과 인접한 배유세포의 단백과립은 퇴행성 변화를 나타내었고, 이로 인해 단백질 기질은 전자밀도가 점진적으로 낮아지는 결과를 얻었는바, 이 시기에 이미 배유의 분해가 시작되고 있음을 나타내는 것이라 할 수 있다. 개갑 이후의 종자에 있어서, 배유세포의 퇴행과정이 더욱 진행됨에 따라 단백과립에는 아직 분해가 이루어지지 않은 부분이 높은 전자밀도를 지닌채 무정형의 형태로 존재하고 있었다. 분해된 단백과립은 단백질 기질의 소실로 액포화되었으며, 이들은 점진적으로 융합과 함께 확장되었다. 퇴행과정과 더불어 스페로솜도 점진적으로 전자밀도가 낮아지면서 분해되었다. 딕티오솜 유래의 소포들은 제형층과 접한 배유세포벽과 인접하여 위치하였으며, 원형질막과 융합하였다. 배유세포이 분해 잔유물로 이루어진 제형층은 다량의 섬유상 물질, 분해가 진행중인 스페로솜, 그리고 toluidine blue와 basic fuchsin에 강한 염색상을 갖는 물질 등으로 이루어져 있었다.

Panax ginseng C. A. Meyer is well known as traditional herbal medicine, and ginseng berries are known to exhibit potential immune-enhancing functions. However, little is known about the in vivo immunomodulatory activity of Korean ginseng berries. In this study, crude Korean ginseng berries polysaccharides (GBP) were isolated and their immunomodulatory activities were investigated using cyclophosphamide (CY)-induced immunosuppressive BALB/c mice. In CY-treated mice, oral administration of GBP (50-500 mg/kg BW) remarkably increased their spleen sizes and spleen indices and activated NK cell activities. GBP also resulted in the proliferation of splenic lymphocytes (coordinating with ConA: plant mitogen which is known to stimulate T-cell or LPS: endotoxin which binds receptor complex in B cells to promote the secretion of pro-inflammatory cytokines) in a dose-dependent manner. In addition, GBP significantly stimulated mRNA expression levels of immune-associated genes including interleukin-1β (IL-1β), IL-2, IL-4, IL-6, tumor necrosis factor-α (TNF-α), interferon-γ (IFN-γ), toll-like receptor 4 (TLR-4), and cyclooxygenase-2 (COX-2) in CY-treated mice. These results indicate that GBP is involved in immune effects against CY-induced immunosuppression. Thus, GBP could be developed as an immunomodulation agent for medicinal or functional food application.

Background: Panax ginseng Meyer (P. ginseng) is a traditional natural/herbal medicine. The amelioration on inflammatory bowel disease (IBD) activity rely mainly on its main active ingredients that are referred to as ginsenosides. However, the current literature on gut microbiota, gut microbiota-host co-metabolites, and systems pharmacology has no studies investigating the effects of ginsenoside on IBD. Methods: The present study was aimed to investigate the role of ginsenosides and the possible underlying mechanisms in the treatment of IBD in an acetic acid-induced rat model by integrating metagenomics, metabolomics, and complex biological networks analysis. In the study ten ginsenosides in the ginsenoside fraction (GS) were identified using Q-Orbitrap LC-MS. Results: The results demonstrated the improvement effect of GS on IBD and the regulation effect of ginsenosides on gut microbiota and its co-metabolites. It was revealed that 7 endogenous metabolites, including acetic acid, butyric acid, citric acid, tryptophan, histidine, alanine, and glutathione, could be utilized as significant biomarkers of GS in the treatment of IBD. Furthermore, the biological network studies revealed EGFR, STAT3, and AKT1, which belong mainly to the glycolysis and pentose phosphate pathways, as the potential targets for GS for intervening in IBD. Conclusion: These findings indicated that the combination of genomics, metabolomics, and biological network analysis could assist in elucidating the possible mechanism underlying the role of ginsenosides in alleviating inflammatory bowel disease and thereby reveal the pathological process of ginsenosides in IBD treatment through the regulation of the disordered host-flora co-metabolism pathway.

저이용 임산자원으로 보고된 꾸지뽕 및 돌배를 이용하여 koji, yeast, LAB을 통한 단일 및 복합 발효를 진행하였고, 복합발효를 이용하는 것이 생리활성물질 전환이 뛰어나다는 것을 확인하였다. 이에 폐 및 기관지에 효능이 있다고 밝혀진 더덕 및 도라지와 혼합하여 국균 및 유용미생물을 활용한 복합발효물의 기간별 분석을 진행하였다. pH와 총산도는 발효초기부터 24일 차까지 큰 변화는 보이지 않았고, 반면 °Brix와 고형분 함량은 6일 차에 급격히 감소하는 경향을 확인하였다. Phenolic compound를 분석한 결과로 chlorogenic acid, 4-hydroxybenzoic acid, vanillic acid, caffeic acid는 발효초기(각 5.43±0.16 ㎍/mL, 12.30±0.17 ㎍/mL, 6.79±0.19 ㎍/mL, 28.14±0.87 ㎍/mL)부터 18일 차까지(각 29.81±0.30 ㎍/mL, 34.22±0.13 ㎍/mL, 28.86±0.50 ㎍/mL, 45.65±0.26 ㎍/mL) 꾸준히 증가하는 반면, ferulic acid, taxifolin, cinnamic acid, quercetin은 12일 차까지 증가하다가(각 23.22±0.67 ㎍/mL, 11.55±0.26 ㎍/mL, 0.84±0.01 ㎍/mL, 1.63±0.02 ㎍/mL) 18일이 지나면서 오히려 감소하는 경향을 보였다(각 17.74±0.19 ㎍/mL, 6.80±0.09 ㎍/mL, 0.72±0.01 ㎍/mL, 1.81±0.02 ㎍/mL). Total phenol, total flavonoid 함량 및 항산화활성(DPPH, ABTS)은 발효 초기부터 18일 차까지 꾸준히 증가하다가 24일부터는 비슷한 수준으로 유지되거나 오히려 감소하는 경향을 보였다. 이는 항산화활성이 높은 성분인 chlorogenic acid, 4-hydroxybenzoic acid, vanillic acid 및 caffeic acid의 함량 변화와 비슷한 경향으로 phenolic compound에 의하는 것으로 판단된다. 또한, NO 생성 억제능을 확인한 결과, 발효초기보다 6일 차 때 NO의 생성이 급격히 억제되는 것을 확인하였고(55.1% to 87.7%), 그 후에는 비슷한 수준을 유지하는 것을 확인하였다. 항염증 관련 단백질 발현 양상 실험에서도 역시 6일 차 이후로 iNOS, COX-2, TNF-𝛼를 억제하는 것을 확인하였다. 따라서 본 연구결과, 꾸지뽕, 돌배, 더덕 및 도라지를 혼합하여 유용미생물(koji, yeast, LAB)을 이용해 복합발효를 했을 시, 12-18일 사이에 항산화 및 항염증 효능이 가장 높은 것을 확인하였다. 이를 통해서 저이용 임산자원의 식품소재로서의 활용 가능성을 확인하였다.

When ginsenoside Rg5, a main component isolated from red ginseng, was incubated with three human fecal microflora for 24 h, all specimens showed hydrolyzing activity: all specimens produced ginsenoside Rh3 as a main metabolite, but a minor metabolite $3{\beta},12{\beta}$-dihydroxydammar-21(22),24-diene (DD) was observed in two specimens. To evaluate the antiallergic effect of ginsenoside Rg5 and its metabolites, the inhibitory effect of ginsenoside Rg5 and its metabolite ginsenoside Rh3 against RBL-2H3 cell degranulation, mouse passive cutaneous anaphylaxis (PCA) reaction induced by the IgE-antigen complex, and mouse ear skin dermatitis induced by 12-O-tetradecanoilphorbol-13-acetate (TPA) were measured. Ginsenosides Rg5 and Rh3 potently inhibited degranulation of RBL-2H3 cells. These ginsenosides also inhibited mRNA expression of proinflammatory cytokines IL-6 and $TNF-{\alpha}$ in RBL-2H3 cells stimulated by IgE-antigen. Orally and intraperitoneally administered ginsenoside Rg3 and orally administered ginsenoside Rg5 to mice potently inhibited the PCA reaction induced by IgE-antigen complex. However, intraperitoneally administered ginsenoside Rg5 nearly did not inhibit the PCA reaction. These ginsenosides not only suppressed the swelling of mouse ears induced by TPA, but also inhibited mRNA expression of cyclooxygenase-2, $TNF-{\alpha}$, and IL-4 and activation of transcription factor NF-kB. These inhibitions of ginsenoside Rh3 were more potent than those of ginsenoside Rg5. These findings suggest that ginsenoside Rg5 may be metabolized in vivo to ginsenoside Rh3 by human intestinal microflora, and ginsenoside Rh3 may improve antiallergic diseases, such as rhinitis and dermatitis.

Objectives : Neuroinflammation is a common pathological mechanism of neurodegenerative diseases, and the development of therapeutic agents is urgently needed. Red ginseng has been known to be good for the immune stimulation in Eastern Asia. Although the immuno-stimulatory activity of red ginseng are already known, the neuro-protective effects of cultivated red ginseng with fermented complex mushroom-cereal mycelium (RGFM) have not been conducted. Thus, in this study, we tried to investigate the anti-neuroinflammatory effect of RGFM water extract on lipopolysaccharide (LPS) stimulated BV2 cells. Methods : BV2 cells were pretreated with RGFM 1 h prior to LPS exposure. To determine the neuro-protective effects of RGFM water extract, we measured the expression of inflammatory mediators including inducible nitric oxide synthase (iNOS), cyclooxygenase (COX)-2 and nitric oxide (NO) and pro-inflammatory cytokines such as interleukin (IL)-1𝛽, IL-6 and tumor necrosis factor (TNF)-𝛼 in LPS-stimulated BV2 cells. In addition, to find out the regulatory mechanism of RGFM water extract, we assessed the protein levels of mitogen-activated protein kinases (MAPKs) and inhibitory 𝜅B𝛼 (I𝜅B𝛼) by western blotting. Results : In our study, treatment of RGFM reduced the mRNA expression of iNOS and COX-2 and suppressed NO production in LPS-stimulated BV2 cells. Additionally, the secretion of IL-1𝛽 and TNF-𝛼 but not IL-6 was significantly inhibited by RGFM. Furthermore, RGFM water extract inhibited the phosphorylation of c-Jun N-terminal kinase (JNK). Conclusions : Taken together, these findings suggest that RGFM water extract has a protective effect on neuroinflammation through inhibition of JNK.
