Ginger (Zingiber officinale Roscoe) is traditionally used as appetite enhancer, improver of the digestive system, antithusive, anti-cold, antipyretic, analgesic, and antiinflammation. In vitro evaluation using human lymphocyte cultures showed almost similar indication with those in in vivo mouse study, NK cell lysing activity was improved significantly. Proliferation activity of B and T cells, and CD3$^{＋}$ and CD3$^{＋}$CD4$^{＋}$T cell subset were better observed using oleoresin or gingerol and shogaol fractions. Although there were higher activities in gingerol, the improvement was almost equal to that by oleoresin. Shogaol did not show better improvement except at higher concentration. It could be concluded that treatment with single bioactive compound, such as gingerol, did not show significant effects compared to oleoresin, the crude extract. In human study, involving healthy male adult, the improvement of NK cell lysing activity was again demonstrated and even more apparent. The mechanism involved in the protection seemed to be through the antioxidant activity of gingerol. However, other mechanism underlying the improvement of NK cell lysing activity must be involved since this improvement seemed to be specifically toward NK cell activity. Since NK cells ave specific for the elimination of virus-infected cell and mutated cells, this positive effect on the immune system are very interesting. This work has also scientifically proved that the traditional beliefs that ginger had preventive effects on common cold appeared to be reasonable.

Background: Gastric ulcer (GU) is a common gastrointestinal disease that can be induced by many factors. Finding an effective treatment method that contains fewer side effects is important. 20 (S)-ginsenoside Rg3 is a kind of protopanaxadiol and has shown superior antiinflammatory and antioxidant effects in many studies, especially cancer studies. In this study, we examined the treatment efficacy of 20 (S)-ginsenoside Rg3 on GU. Methods: Three kinds of GU models, including an alcohol GU model, a pylorus-ligated GU model, and an acetic acid GU model, were used. Mouse endothelin-1 (ET-1) and nitric oxide (NO) levels in blood and epidermal growth factor (EGF), superoxide dismutase, and NO levels in gastric mucosa were evaluated. Hematoxylin and eosin staining of gastric mucosa and immunohistochemical staining of ET-1, inducible nitric oxide synthase (NOS2), and epidermal growth factor receptors were studied. Ulcer index (UI) scores and UI ratios were also analyzed to demonstrate the GU conditions in different groups. Furthermore, Glide XP from $Schr{\ddot{o}}dinger$ was used for molecular docking to clarify the interactions between 20 (S)-ginsenoside Rg3 and EGF and NOS2. Results: 20 (S)-ginsenoside Rg3 significantly decreased the UI scores and UI ratios in all the three GU models, and it demonstrated antiulcer effects by decreasing the ET-1 and NOS2 levels and increasing the NO, superoxide dismutase, EGF, and epidermal growth factor receptor levels. In addition, high-dose 20 (S)-ginsenoside Rg3 showed satisfactory gastric mucosa protection effects. Conclusion: 20 (S)-ginsenoside Rg3 can inhibit the formation of GU and may be a potential therapeutic agent for GU.

Background: Ginseng has a wide range of beneficial effects on health, such as the mitigation of minor and major inflammatory diseases, cancer, and cardiovascular diseases. There are abundant data regarding the health-enhancing properties of whole ginseng extracts and single ginsenosides; however, no study to date has determined the receptors that mediate the effects of ginseng extracts. In this study, for the first time, we explored whether the antiinflammatory effects of Rg3-enriched red ginseng extract (Rg3-RGE) are mediated by retinoid X receptor ${\alpha}$-peroxisome-proliferating receptor ${\gamma}$ ($RXR{\alpha}-PPAR{\gamma}$) heterodimer nuclear receptors. Methods: Nitric oxide assay, 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazoliumbromide assay, quantitative reverse transcription polymerase chain reaction, nuclear hormone receptor-binding assay, and molecular docking analyses were used for this study. Results: Rg3-RGE exerted antiinflammatory effects via nuclear receptor heterodimers between $RXR{\alpha}$ and $PPAR{\gamma}$ agonists and antagonists. Conclusion: These findings indicate that Rg3-RGE can be considered a potent antiinflammatory agent, and these effects are likely mediated by the nuclear receptor $RXR{\alpha}-PPAR{\gamma}$ heterodimer.

Objectives The object of this study was to investigate the antioxidative and antiinflammatory effects of Jinmu-tang extract (JMT) on the Monosodium iodoacetate (MIA)-induced rat osteoarthritis. Methods To investigate the antioxidant capacities of JMT, we measured the total polyphenol and flavonoid, and 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2'-Azino-bis(3-ethyl-benzothiazoline-6-sulfonic acid) (ABTS) radical scavenging activity. To evaluate the antioxidative and antiinflammatory effects of JMT, the rats were divided into 5 groups (n=8). Normal group was not induced by MIA and treated at all (N), control group was induced by MIA and not treated at all (Con), positive control group was induced by MIA and orally administered indomethacin 5 mg/kg (Indo) and experimental groups were induced by MIA and orally administered JMT 100 mg/kg (JMT100) and JMT 200 mg/kg (JMT200) for 4 weeks. The changes of anti-type II collagen antibody in serum, heme oxygenase-1 (HO-1), phosphorylated inhibitor of ${\kappa}B{\alpha}$ ($p-I{\kappa}B{\alpha}$), cyclooxygenase-2 (COX-2), inducible nitric oxide synthase (iNOS) and tumor necrosis factor alpha ($TNF-{\alpha}$) in knee joint tissue and histopathological observation (Hematoxylin & Eosin and Safranin-O stain) were measured. Results Total polyphenol and flavonoid levels of JMT were $26.90{\pm}0.33mg/g$ and $6.02{\pm}0.34mg/g$. $IC_{50}$ of L-ascorbic acid and JMT of DPPH radical scavenging activity were $1.35{\pm}0.07{\mu}g/ml$ and $52.95{\pm}0.97{\mu}g/ml$. $IC_{50}$ of L-ascorbic acid and JMT of ABTS radical scavenging activity were $3.18{\pm}0.02{\mu}g/ml$ and $91.49{\pm}1.74{\mu}g/ml$. In serum, the anti-type II collagen antibody levels of JMT100 and JMT200 groups were decreased significantly. In knee joint tissue, the HO-1 level of JMT200 was increased significantly. The $p-I{\kappa}B{\alpha}$ and $TNF-{\alpha}$ levels of JMT200 were decreased significantly. The COX-2 and iNOS levels of JMT groups were decreased significantly. In histopathological observation, in comparison with Con, synovial tissue, cartilage and proteoglycan of JMT100 and JMT200 were well preserved. Conclusions According to the results, It is considered that JMT has antioxidant and antiinflammatory effects for MIA-induced rat osteoarthritis, so it could be applied to osteoarthritis treatment.
