  • Background: In general, after Panax ginseng is administered orally, intestinal microbes play a crucial role in its degradation and metabolization process. Studies on the metabolism of P. ginseng by microflora are important for obtaining a better understanding of their biological effects. Methods: In vitro biotransformation of P. ginseng extract by rat intestinal microflora was investigated at $37^{\circ}C$ for 24 h, and the simultaneous determination of the metabolites and metabolic profile of P. ginseng saponins by rat intestinal microflora was achieved using LC-MS/MS. Results: A total of seven ginsenosides were detected in the P. ginseng extract, including ginsenosides Rg1, Re, Rf, Rb1, Rc, Rb2, and Rd. In the transformed P. ginseng samples, considerable amounts of deglycosylated metabolite compound K and Rh1 were detected. In addition, minimal amounts of deglycosylated metabolites (ginsenosides Rg2, F1, F2, Rg3, and protopanaxatriol-type ginsenosides) and untransformed ginsenosides Re, Rg1, and Rd were detected at 24 h. The results indicated that the primary metabolites are compound K and Rh1, and the protopanaxadiol-type ginsenosides were more easily metabolized than protopanaxatriol-type ginsenosides. Conclusion: This is the first report of the identification and quantification of the metabolism and metabolic profile of P. ginseng extract in rat intestinal microflora using LC-MS/MS. The current study provided new insights for studying the metabolism and active metabolites of P. ginseng.

  • Objective : The present experiments were designed to study on the immune-enhancing effect of Mountain grown ginseng, Mountain cultivated ginseng, and Panax ginseng Method : In order to compare the immune-enhancing effect of moutain grown ginseng, moutain cultivated ginseng and Panax ginseng, the study was done through the forced swimming test (FST), measurement of T helper Th1, Th2 cytokines and fatigue related factors. Result : Moutain grown ginseng and panax ginseng decreased the immobility time in the FST compared to the control. Glucose, blood urea nitrogen (BUN), creatinine, lactate dehydrogenase (LDH) and Total-protein (T-protein) in serum were investigated. The serum achieved from ginseng administered mouse showed higher BUN, T-protein than the control. moutain grown ginseng administered group showed lower LDH than the control group. moutain grown ginseng administered mouse showed higher glucose than the control. Creatinine was same in either experimental or control group. Ginseng-induced cytokine production in human T-cell line, MOLT-4 cells and mouse peritoneal macrophages were compared. Moutain cultivated ginseng (10-4 dilution) and panax ginseng (10-3 dilution) were increased the interferon $IFN-{\gamma}$ production compared with media control (about 1.6-fold P<0.05) at 48 h. Moutain grown ginseng (10-4 dilution) was increased the $IFN-{\gamma}$ and interleukin IL-4 production compared with media control (about l.4-fold for $IFN-{\gamma}$ and 1.6-fold for IL-4 P<0.05) at 48 h. Moutain grown ginseng (10-3 dilution) and moutain cultivated ginseng (10-4 dilution) were increased the turmor necrosis factor $TNF-{\alpha}$ production compared with $rIFN-{\gamma}$ treated cells (about 1.9-fold for $TNF-{\alpha}$ P<0.05), respectively. Moutain cultivated ginseng (10-3 dilution) was increased the IL-12 production compared with $rIFN-{\gamma}$ treated cell (about 1.7-fold for IL-12 P<0.05). Conclusion : These data suggest that three different three kinds of ginseng act on immune responses in different aspects.

  • Background: Panax ginseng Meyer polysaccharides exhibit various biological functions, like antagonizing galectin-3-mediated cell adhesion and migration. Galectin-8 (Gal-8), with its linker-joined N- and C-terminal carbohydrate recognition domains (CRDs), is also crucial to these biological processes, and thus plays a role in various pathological disorders. Yet the effect of ginseng-derived polysaccharides in modulating Gal-8 function has remained unclear. Methods: P. ginseng-derived pectin was chromatographically isolated and enzymatically digested to obtain a series of polysaccharides. Biolayer Interferometry (BLI) quantified their binding affinity to Gal-8, and their inhibitory effects on Gal-8 was assessed by hemagglutination, cell migration and T-cell apoptosis. Results: Our ginseng-derived pectin polysaccharides consist mostly of rhamnogalacturonan-I (RG-I) and homogalacturonan (HG). BLI shows that Gal-8 binding rests primarily in RG-I and its β-1,4-galactan side chains, with sub-micromolar KD values. Both N- and C-terminal Gal-8 CRDs bind RG-I, with binding correlated with Gal-8-mediated function. Conclusion: P. ginseng RG-I pectin β-1,4-galactan side chains are crucial to binding Gal-8 and antagonizing its function. This study enhances our understanding of galectin-sugar interactions, information that may be used in the development of pharmaceutical agents targeting Gal-8.

  • We previously reported that in vitro anti-platelet activity of tissue-cultured mountain ginseng (TCMG) ethanol extracts show improved efficacy when compared with commercial ginseng products such as Korean red ginseng and Panax ginseng. However, information on the anti-platelet activity of the ethyl acetate fraction from TCMG adventitious roots is limited. Therefore, in this study, we further investigated the effects of an ethyl acetate extract of TCMG (EA-TCMG) adventitious roots on in vitro antiplatelet activity in whole human blood and its effect on peripheral blood flow in mice. We found that EA-TCMG inhibited platelet aggregation with $IC_{50}$ values of 271, 180, and 147 ${\mu}g$/mL induced by collagen, adenosine-5'-diphosphate, and arachidonic acid, respectively. Among the three agonists used, thromboxane $A_2$ formation induced by arachidonic acid was markedly suppressed. Furthermore, EA-TCMG improved the peripheral circulatory disturbance by improving vascular blood flow. In conclusion, these results suggest that ethyl acetate extracts from TCMG adventitious roots might inhibit vascular platelet aggregation and thrombus formation.

  • Present study investigated the effects of the 70% ethanol extracts of tissue-cultured mountain ginseng (TCMG), Korean red ginseng (KRG), and Panax ginseng (PG) on agonist-induced platelet aggregation and activation in human whole blood. The $IC_{50}$ values for TCMG, KRG, and PG were 1.159, 3.695, and 4.978mg/mL for collagen-induced aggregation, 0.820, 2.030, and 4.743mg/mL for arachidonic acid-induced aggregation, and 1.070, 2.617, and 2.954 mg/mL for ADP-induced aggregation, respectively. Also, this study assessed the effects of the most active extract, TCMG, on markers of platelet activation by determining receptor expression on platelet membranes in healthy subjects, including expression of GPIIb/IIIa-like (PAC-1) and P-selectin (CD62), by flow cytometry. A significant decrease in PAC-l expression (p=0.018) was observed in the presence of TCMG. These results show that TCMG has potent anti-platelet activity.

  • Objectives: Mountain ginseng pharmacopuncture (MGP) is an extract distilled from either mountain cultivated ginseng or mountain wild ginseng. This is the first intravenous injection of pharmacopuncture in Korea. The word intravenous does not discriminate between arteries, veins, and capillaries in Oriental Medicine, but only the vein is used for MGP. The aim of this study is to evaluate the intravenous injection toxicity of MGP through a single-dose test in Sprague-Dawley (SD) rats. Methods: Male and female 6-week-old SD rats were injected intravenously with MGP (high dosage of 20 mL/kg or low dosage of 10 mL/kg). Normal saline was injected into the rats in the control group by using the same method. After the rats has treated, we conducted clinical observations, body-weight measurements and histological observations. Results: In this study, no mortalities were observed in any of the experimental groups. Also, no significant changes by the intravenous injection of MGP were observed in the body weights, or the histological observations in any of the experimental groups compared to the control group. The lethal dose for intravenous injection of MGP was found to be over 20 mL/kg in SD rats. Conclusion: Considering that the dosage of MGP generally used each time in clinical practice is about 0.3 mL/kg, we concluded with confidence that MGP is safe pharmacopuncture.

  • Objectives: Mountain ginseng pharmacopuncture (MGP) is a pharmacopuncture made by distilling extract from mountain cultivated ginseng or mountain wild ginseng. This pharmacopuncture is injected intravenously, which is a quick, lossless way of strongly tonifying Qi function. The present study was undertaken to evaluate a 4-week, repeated, intravenous injection, toxicity test of MGP in Sprague-Dawley (SD) rats. Methods: Twenty male and female 6-week-old SD rats were used as subjects. We divided the SD rats into 4 groups: the high-dosage (10 mL/kg), medium-dosage (5 mL/kg), low-dosage (2.5 mL/kg) and control (normal saline) groups. MGP or normal saline was injected intravenously into the caudal vein of the rats once daily for 4 weeks. Clinical signs, body weights, and food consumption were monitored during the observation period, and hematology, serum biochemistry, organ weight, necropsy, and histological examinations were conducted once the observations had been completed. Results: No mortality was observed in any of the groups during the observation period. No changes due to MGP were observed in the experimental groups regarding clinical signs, body weights, food consumption, hematology, serum biochemistry, organ weight and necropsy. No histological changes due to MGP were observed in any of the male or female rats in the high-dosage group. Conclusion: During this 4-week, repeated, intravenous injection, toxicity test of MGP in SD rats, no toxic changes due to MGP were observed in any of the male or female rats in the high-dosage group. Thus, we suggest that the high and the low doses in a 13-week, repeated test should be 10 mL/kg and 2.5 mL/kg, respectively.
