Purpose: This study was performed to evaluate anti-oxidant activities and anti-inflammatory effects of Sungyoutanggagambang(SYTG). Methods: In the study of anti-oxidant activities. SYTG was investigated by DPPH radical scavenger activity. superoxide dismutase activity and superoxide anion radical scavenger activity. In the study of anti-inflammatory effects. SYTG was investigated using cultured cells and murine models. As for the parameters of inflammation. levels of several inflammatory cytokines and chemical mediators which are known to be related to inflammation were measured in mouse lung fibroblast cells(mLFCs) and RAW264.7 cells. Results: Prior to the experiment. we investigated the security of SYTG by measuring GOT and GPT in serum. 1. SYTG showed high antioxidant activity in a concentration-dependent degree by measured scavenging activity of DPPH free radical, superoxide dismutase and superoxide anion radical. 2. SYTG inhibited IL-1$\beta$, IL-6. TNF-$\alpha$, COX-2 and NOS-II mRNA expression as compared with the control group in a concentration-dependent degree in RAW264.7 cell line. 3. SYTG inhibited IL-1$\beta$, IL-6 production significantly at 100 ${\mu}g/ml$ and TNF-$\alpha$ production significantly at 50, 100 ${\mu}g/ml$ as compared with the control group in RA W264.7 cell line. 4. SYTG inhibited IL-1$\beta$, and IL-6 production significantly as compared with the control group in serum of acute inflammation-induced mice. and decreased IL-1$\beta$, IL-6 production in spleen tissue. and also decreased IL-1$\beta$, IL-6 production in liver tissue.

Although marine living organism contains a numerious number of compounds, it is difficult to collect these compounds in a large scale for medicinal application. However, in recent years, several bioactive compounds isolated from marine macroalgae have been proved to be able to provide potential sources for development of medicinal products because they can be obtained in large amount from marine. A number of studies have reported a variety of effects of marine macroalgae but a few anti-inflammatory activity of marine macroalgae have recently been published. Herein, we reviewed novel anti-inflammatory compounds recently isolated from marine brown algae, green algae and red algae. From this survey, in particular, some compounds contained in edible macroalgae exert anti-inflammatory effects with inhibition on cyclooxygenase-2 (COX-2), inducible nitric oxide synthase(iNOS) and matrix metalloproteinases (MMPs) activity regulated by nuclear factor-kappa B transcription factor that play a key role in cancer as well as inflammation, demonstrating to be able to potentially apply to development of anti-inflammatory agent for chemoprevention of cancer. Furthermore, some macroalgae and their compounds with both excellent anti-inflammatory activity and very low toxicity can select a potential candidates capable of preventing or treating several chronic inflammation such as colitis, hepatitis and gastritis, leading to cancer.

The study examined the antioxidant activities and anti-inflammatory effects of rutin from the streptozotocin (STZ)-induced diabetic rats. Results revealed that the levels of plasma glucose and serum glucose were remarkably higher in the STZ-treated group compared to other groups and were significantly reduced in the STZ+rutin treated group compared to the STZ-treated group. In terms of weight, it significantly increased in all experimental groups during the experiment period except for STZ-induced diabetic group. The weight of the STZ-treated group was remarkably reduced compared to other groups. Regarding the weight of each body organ, the STZ-treated group showed higher organ weight compared to the other groups while STZ+rutin-treated group showed significantly reduced kidney and liver weights compared to those of STZ-treated group. In the pancreas tissue of the STZ-treated group, ${\beta}$-cell destruction and vacuolization were observed. Inflammation in the heart, liver, kidney, and retina tissues were also vividly recorded. In the STZ+rutin administered group, the heart and retina tissues were shown to be preserved normally while the liver and kidney tissues showed reduced histopathology in general compared to the STZ-treated group. Conclusionally, the rutin has the effect on the antioxidant activities and anti-inflammation in the STZ-induced diabetic rats.

4,4'-diaminodiphenyl sulfone (dapsone) is a sulfone drug that has antibacterial effects on a variety of bacteria, especially Mycobacterium leprae; thus, it has been used to treat leprosy. Previous studies demonstrated that dapsone inhibits integrin-mediated adherence of neutrophils and production of prostaglandin $E_2$ by polymorphonuclear leukocytes. Hence, dapsone may act in immune cells and regulate cell-mediated inflammation processes. However, its anti-inflammatory effects remain unclear. The present study demonstrated that dapsone modulates the production of inflammation-related cytokines in immune cells. We employed the spleen cells of mice, which are major immune cells, and lipopolysaccharide (LPS) as a causative agent of inflammation for experiments. Dapsone induced a proportional change in splenocyte subsets and the apoptosis of spleen cells. Interestingly, dapsone decreased the production of tumor necrosis factor-alpha and interleukin (IL)-10, but not IL-6, in LPS-treated spleen cells. In other assays, we measured the dapsone-induced production of nitric oxide (NO) and the expression of activation markers of spleen cells. Dapsone decreased NO production in LPS-treated spleen cells. Taken together, our results demonstrate that dapsone has anti-inflammatory effects in immune cells and provide new insight into the potential uses of this agent.

Water and chloroform/methanol extracts of the three local Malaysian snakehead fish, Channa striatus (striped snakehead), Channa micropeltes (giant snakehead) and Channa lucius (blotched snakehead) were evaluated for inhibitory activity in chronic inflammation, using cotton pellet granuloma test. Both water extracts of C. striatus and C. micropeltes showed marked inhibition of the transudative and proliferative components of chronic inflammation (42.9 and 31.2% respectively for C. striatus, 35.6 and 26.2% for C. micropeltes) when compared to those of mefenamic acid (25.1 and 21.3% respectively) and piroxicam (36.1 and 26.2% respectively). The chloroform/methanol extracts did not exhibit any anti-inflammatory effects. These results indicated that C. striatus has more anti-transudative and anti-proliferative activities than the extract of C. micropletes. C. lucius extract in contrast, did not inhibit these two components. This present study indicated the beneficial effects of the water extracts of C. striatus and C. micropeltes, but not C. lucius on chronic inflammation.

Oroxylum indicum has long been used in Asian traditional medicine to prevent and treat respiratory diseases, diabetes, diarrhea and other conditions. Oroxylin A is a flavone that is present in Oroxylum indicum and in Scutellaria baicalensis. Because the root extracts of both plants have been shown to have anti-allergic effects, the authors investigated whether oroxylin A is likely to have beneficial effects on allergic asthma using female Balb/c mice and rat RBL-2H3 mast cells. Antigen-induced degranulation was measured in vitro by measuring b-hexosaminidase activity. A murine ovalbumin-induced allergic asthma model was used to test the in vivo efficacy of oroxylin A. Sensitization and challenge of ovalbumin induced allergic asthma responses, the accumulations of eosinophils and Th2 cytokine levels in bronchoalveolar lavage fluid and lung tissues. Oroxylin A administration decreased numbers of inflammatory cells, especially eosinophils, and reduced the expression and secretion of Th2 cytokines, including IL-4 and IL-13, in lung tissues and bronchoalveolar lavage fluid. Histologic studies showed oroxylin A reduced inflammatory signs and mucin production in lungs. These findings provide evidence that oroxylin A has potential use as an anti-allergic therapeutic.

Culinary mushroom Pleurotus pulmonarius has been popular in Asian countries. In this study, the anti-oxidant, cholinesterase, and inflammation inhibitory activities of methanol extract (ME) of fruiting bodies of P. pulmonarius were evaluted. The 1,1-diphenyl-2-picryl-hydrazy free radical scavenging activity of ME at 2.0 mg/mL was comparable to that of butylated hydroxytoluene, the standard reference. The ME exhibited significantly higher hydroxyl radical scavenging activity than butylated hydroxytoluene. ME showed slightly lower but moderate inhibitory activity against acetylcholinesterase (AChE) and butyrylcholinesterase than galantamine, a standard AChE inhibitor. It also exhibited protective effect against cytotoxicity to PC-12 cells induced by glutamate ($10{\sim}100{\mu}g/mL$), inhibitory effect on nitric oxide (NO) production and inducible nitric oxide synthase protein expression in lipopolysaccharide-stimulated RAW 264.7 macrophages, and carrageenan-induced paw edema in a rat model. High-performance liquid chromatography analysis revealed the ME of P. pulmonarius contained at least 10 phenolic compounds and some of them were identified by the comparison with known standard phenolics. Taken together, our results demonstrate that fruiting bodies of P. pulmonarius possess antioxidant, anti-cholinesterase, and inflammation inhibitory activities.
