  • Ginkgetin was previously reported as an inhibitor of group II phospholipase A$_2$. It also inhibited in vitro arachidonate release from the activated macrophages and lymphocyte proliferation. These previous studies suggested an anti-inflammatory nature of ginkgetin, especially on chronic inflammation. In fact, ginkgetin showed potent anti-inflammatory activity against rat adjuvant-induced arthritis, a chronic inflammatory animal model, with comparable analgesic activity. In order to investigate the action mechanisms, tumor necrosis factor and interferone release were studied from human PMMC. It was found that ginkgetin clearly inhibited release of these cytoknes from human PMMC. Ginkgetin was also found to inhibit immunoglobulin M production at 1 - 10 uM. These results may contribute to antiarthritic activity of ginkgetin in vivo.

  • Glehnia littoralis (Umbelliferae), a perennial herb distributed along the coastline of northern Pacific countries, is the medicinal plant used traditionally for treatment of various diseases. This review focuses on the various pharmacological activities of Glehnia littoralis for understanding about its traditional medicinal applications, medicinal uses in the modern society, and potentials for drug development Glehnia littoralis was reported to have anti-oxidant, anti-tumor, anti-amnesic, blood circulation-promoting, immunomodulatory, anti-microbial, and allelopathic activities. However, their mechanisms remain to be clarified. Because Glehnia littoralis has been prescribed in traditional Oriental medicine as a tonic herb, Glehnia littoralis can be better than other chemical drugs and medicines which exert the equal pharmacological activities. Although the activities of Glehnia littoralis are not specifically high-potent with unique mode of action, it may turn out that it can be beneficial to exert multiple pharmacological activities. In view of low toxicity, relative cheapness, presence in the diet, and occurrence in various herbal remedies of Glehnia littoralis, it needs to be prudent to evaluate its properties and applications further.

  • Saussurea lappa (SL) and major compounds, sesquiterpene lactones, have been suggested to possess various biological effects, including anti-tumor, anti-ulcer, anti-inflammatory, anti-viral and cardiotonic activities. Therefore, the ethanol extract of Saussurea lappa root (ESL) is studied for the mechanism of its action in apoptotic pathway. ESL-treated cells manifested nuclear condensation, and fragmentation. ESL also triggered the mitochondrial apoptotic pathway, as indicated by a change in Bax/Bcl2 ratio and caspase-9/-3 activation. ESL induced p38 MAPK/JNK, p53, and ASK1 phosphorylation. ROS scavenger reversed ESL-induced apoptotic cell death via inhibition of caspase-3 and p38 MAPK/JNK phosphorylation. These results suggest that ESL induced apoptosis in HepG2 cells through the ROS-p38/JNK pathway.

  • Objective : The aim of this study is to investigate the anti-inflammatory effects of 15Hz electroacupuncture(EA) on carrageenan-injected rats. Inflammation was induced by an intraplantar injection of 1% carrageenan into the right hind paw. Methods : Bilateral EA stimulation with 15 Hz were delivered at those acupoints corresponding to Zusanli and Sanyinjiao in man via the needles for a total of 30 min duration in carrageenan-injected rats. Results: The developing edema was measured 30 minutes interval afer carrageenan injection and 15 Hz EA stimulation presented significant edema inhibition. Three hours after carrageenan injection, prostaglandin $E_2(PGE_2)$ and nitric oxide(NO) levels were measured. The 15Hz EA stimulation significantly inhibited $PGE_2$ and NO production in the right paw. The pro-inflammatory mRNA expression such as cyclooxygenases(COX)-2 and interleukin(IL)-$1{\beta}$ were slightly down-regulated by EA stimulation. The number of COX-2, IL-$1{\beta}$, tumor necrosis factor-${\alpha}$ immunoreactive cells were abundantly observed in paw edema. But these cells were decreased in nmber according to anti-edema effect of 15Hz EA. Conclusions: These results indicate that 15Hz EA stimulation have an alleviation action against carrageenan-induced edema and local inflammation.

  • Sesquiterpene-quinone is a class of secondary metabolites frequently encountered from marine sponge. The present study was designed to examine the anti-inflammatory action of sponge-derived dactyloquinone B (DQB) and cyclospongiaquinone-1 (CSQ1) mixture using lipopolysaccharide (LPS)-induced inflammatory responses. We measured the production of nitric oxide (NO), tumor necrosis factor-alpha ($TNF-{\alpha}$), $interleukin-1{\beta}$ ($IL-1{\beta}$), and interleukin-6 (IL-6) and expression of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) protein. $TNF-{\alpha}$, $IL-1{\beta}$, and IL-6 production, which increased by treatment with LPS, were significantly inhibited by DQB and CSQ1 mixture. It also decreased the production of NO production, and iNOS and COX-2 expression. Furthermore, it reduced 12-O-tetradecanoylphorbol 13-acetate (TPA)-induced ear edema of ICR mice. These results demonstrate that sesquiterpene-quinone, DQB and CSQ1 mixture, might serve as a chemical pipeline for the development of anti-inflammatory agent.

  • In South America, natural products with unknown drug effects are used as folk remedies and for preventive medicine. Among South American natural products, we directed our attention to Propolis, which have been known as medicinal plants, and examined the mechanisms by which these substances affect antioxidant activity, anti-tumor activity and immunoresponse. When the antioxidant activities of Propolis were examined by the DPPH and Rhoudan iron methods, since Propolis contains high levels of flavonoids, it is thought that flavonoids may be responsible for the antioxidant activity in this study. In the examination of immunoenhancement activity, we measured lymphocyte versus polymorphonuclear leukocyte ratios (L/P activity). The number of lymphocytes was significantly increased in groups treated with Proplolis. Specifically, slightly high levels of $IFN-{\gamma}$ were measured in mice bearing the S-180 carcinoma, after administration of Propolis. This strongly suggests that cellular immunity is especially activated by treatment with Propolis, because production of $IFN-{\alpha}$ is limited to the T cells and NK cells stimulated by mitogen and sensitized antigen. $TNF-{\alpha}$ shows a different extent and mechanism of action depending on the target cells. When $TNF-{\alpha}$ was measured in mice bearing the S-180 carcinoma, mice treated with Propolis showed slightly higher $TNF-{\alpha}$ levels as compared to the control group. This suggests that activated macrophages produce $TNF-{\alpha}$ in mice treated with Prapolis, since activated macrophages and lymphocytes are the source of most $TNF-{\alpha}$. When anti-tumor action was examined using two kinds of sarcoma (Ehrlich solid carcinoma and Sarcoma-180 carcinoma), tumor-suppressive ratios after treatment with Propolis was 29.1%. When Sarcoma-180 solid carcinoma was used, tumor-suppressive ratios were 62%. Thus, Propolis showed strong anti-tumor activity against two kinds of solid carcinoma. Taken altogether, this strongly suggests that Propolis enhances original functions of macrophages and NK cells, and as a result, secondarily enhances the immune reaction and suppresses tumor growth.

  • Cordyceps is a traditional Chinese medicinal herb well-known in China, Korea and Japan since B.C. 2,000. The original entomopathogenic fungus, Cordyceps sinensis belonging to the genus Cordyceps could not be found inside Korean peninsula due to the absence of the host insect for the corresponding entomogenous fungus. The development of artificial production methods of Korean type Cordyceps using the silkworm Bombyx mori as in vivo culture medium for the the entomopathogenic fungus Paecilomyces tenuipes is the first, and wonderful occasion in the research history of insect industry of this global world. The aim of this article is to review the historical research background, mass-production methods, and pharmacological effects of the silkworm-dongchunghacho (Paecilomyces tenuipes) which is a newly developed Korean medicinal insect-borne mushroom, and another non-insect-borne medicinal mushroom (Cordyceps militaris and Cordyceps pruinosa). Their biological actions include anti-tumor, immunostimulating, anti-fatigue, anti-stress, anti-oxidant, anti-aging, anti-diabetic, anti-inflammatory, anti-thrombosis, hypolipidaemic and insecticidal effects. The bioactive principles are protein-bound polysaccharides (hexose, hexosamin), cordycepin, D-manitol, acidic polysaccharide etc. Protein-bound polysaccharides and n-butanol fractions were demonstrated to show a significant anti-tumor activities but did not show a cytotoxicities. D-mannitol exhibited a significant prolongation of the life span in tumor bearing mice. Ergosterol did not show an efficient anti-tumor activity, but showed a significant phagocytosis enhancing activity. Anti-tumor activity of silkworm-dongchunghacho might be attributed to immuno-stimulating activities rather than cytotoxic effects [164]. Also this review comprises the breeding of Dongchunghacho varieties, optimization of culture conditions, improvement of learning and memory by Dongchunghacho, application of them as foods and chemical constituents.

  • Background: Ginseng saponin has long been used as a traditional Asian medicine and is known to be effective in treating various kinds of pain. Ginsenoside Rf is one of the biologically active saponins found in ginseng. We evaluated ginsenoside Rf's antinociceptive and anti-inflammatory effects, and its mechanism of action on adrenergic and serotonergic receptors, in an incisional pain model. Methods: Mechanical hyperalgesia was induced via plantar incision in rats followed by intraperitoneal administration of increasing doses of ginsenoside Rf (vehicle, 0.5 mg/kg, 1 mg/kg, 1.5 mg/kg, and 2 mg/kg). The antinociceptive effect was also compared in a Positive Control Group that received a ketorolac (30 mg/kg) injection, and the $Na{\ddot{i}}ve$ Group, which did not undergo incision. To evaluate the mechanism of action, rats were treated with prazosin (1 mg/kg), yohimbine (2 mg/kg), or ketanserin (1 mg/kg) prior to receiving ginsenoside Rf (1.5 mg/kg). The mechanical withdrawal threshold was measured using von Frey filaments at various time points before and after ginsenoside Rf administration. To evaluate the anti-inflammatory effect, serum interleukin $(IL)-1{\beta}$, IL-6, and tumor necrotizing $factor-{\alpha}$ levels were measured. Results: Ginsenoside Rf increased the mechanical withdrawal threshold significantly, with a curvilinear dose-response curve peaking at 1.5 mg/kg. $IL-1{\beta}$, IL-6, and tumor necrotizing $factor-{\alpha}$ levels significantly decreased after ginsenoside Rf treatment. Ginsenoside Rf's antinociceptive effect was reduced by yohimbine, but potentiated by prazosin and ketanserin. Conclusion: Intraperitoneal ginsenoside Rf has an antinociceptive effect peaking at a dose of 1.5 mg/kg. Anti-inflammatory effects were also detected.

  • Nonsteroidal anti-inflammatory drugs such as indomethacin (IN) can exert anti-colorectal cancer (CRC) activity through cyclooxygenase independent mechanism, but the exactly biological mechanism is not completely known. Here we use proteomic tools to investigate the molecular mechanism of this action. First, nude mice bearing tumors derived from subcutaneous injection with human CRC cell line HCT116 were randomly allocated to groups treated with or without indomethacin. Later, tumor lumps were incised and then total proteins extracted. After separated with two-dimensional electrophoresis, thirty-one differently expressed spots were found between IN-treated and non-IN-treated groups, of which 25 spots decreased and 6 spots increased in abundance in IN-treated group. Through matrix-assisted laser desorption ionization time of flight mass spectrometry and then NCBInr and SWISS-PROT databases searching, 12 protein spots were finally identified including galectin-1, annexin A1, annexin IV, trancription factor BTF3A, calreticulin. Most of the identified proteins are correlated with tumor's biological prosperities of proliferation, invasion, apoptosis and immunity, or take part in cell's signal transduction. From above we thought that indomethacin can exert its effect on colorectal cancer through regulating several proteins' expression directly or indirectly. Further study of these proteins may be helpful in founding new targets of drugs for cancer chemotherapy.
