BACKGROUND/OBJECTIVES: Previous studies have reported that protein supplementation contributes to the attenuation of inflammation. Serious trauma such as burn injury usually results in the excessive release of inflammatory factors and organs dysfunction. However, a few reports continued to focus on the function of protein ingestion in regulating burn-induced inflammation and organ dysfunction. MATERIALS/METHODS: This study established the rat model of 30% total body surface area burn injury, and evaluated the function of blended protein (mixture of whey and soybean proteins). Blood routine examination, inflammatory factors, blood biochemistry, and immunohistochemical assays were employed to analyze the samples from different treatment groups. RESULTS: Our results indicated a decrease in the numbers of white blood cells, monocytes, and neutrophils in the burn injury group administered with the blended protein nutritional support (Burn+BP), as compared to the burn injury group administered normal saline supplementation (Burn+S). Expressions of the pro-inflammatory factors (tumor necrosis factor-α and interleukin-6 [IL-6]) and chemokines (macrophage chemoattractant protein-1, regulated upon activation normal T cell expressed and secreted factor, and C-C motif chemokine 11) were dramatically decreased, whereas anti-inflammatory factors (IL-4, IL-10, and IL-13) were significantly increased in the Burn+BP group. Kidney function related markers blood urea nitrogen and serum creatinine, and the liver function related markers alanine transaminase, aspartate aminotransferase, alkaline phosphatase, and lactate dehydrogenase were remarkably reduced, whereas albumin levels were elevated in the Burn+BP group as compared to levels obtained in the Burn+S group. Furthermore, inflammatory cells infiltration of the kidney and liver was also attenuated after burn injury administered with blended protein supplementation. CONCLUSIONS: In summary, nutritional support with blended proteins dramatically attenuates the burn-induced inflammatory reaction and protects organ functions. We believe this is a new insight into a potential therapeutic strategy for nutritional support of burn patients.

Adipocytes are endocrine cells that release bioactive mediators called adipokines. In condition of obesity characterized by low-grade chronic inflammation, adipocytes release inflammatory adipokines, which is related to insulin resistance. Bojungchiseub-tang (BJCST) has been used in symptoms and signs of edema, dampness-phlegm, kidney failure, and so on in Korean medicine. BJCST is also expected to have anti-obesity activities. In the present study, we examined whether BJCST modulate the production of inflammatory adipokines and the activations of the mitogen-activated protein kinases (MAPK) signaling pathway related to induce adipocyte inflammation to elucidate the effects and its mechanism of BJCST on lowering the content of inflammatory adipokines in 3T3-L1 adipocytes. As a result, BJCST suppressed the production of proinflammatory cytokines, tumor necrosis factor (TNF) $-{\alpha}$, interleukin (IL) $-1{\beta}$, IL-6, interferon (IFN) -${\gamma}$, granulocyte-macrophage colony-stimulating factor (GM-CSF), monocyte chemoattractant protein-1 (MCP-1), and the production of other inflammatory mediators, prostaglandin $E_2(PGE_2)$ and nitric oxide(NO)viadownregulationofcyclooxygenase-2(COX-2)andinducible NO synthase (iNOS) gene expressions. In addition, BJCST decreased the phosphorylation of MAPK that promotes the production of inflammatory adipokines in 3T3-L1 mature adipocytes. In conclusion, BJCST could regulate the production of inflammatory adipokines and MAPK signaling pathway related to induction of adipose inflammation.

This study was conducted to investigate the effects of several additives(macroalgae, wasabi, and herb) in formulated diets on the growth, body composition, blood chemistry and non-specific immune response of juvenile flounder. Three replicates of juveniles (average weight 8.4 g) in flow-through aquarium system were fed one of six isonitrogenous (45%) and isolipidic (8%) diets containing 5 and 10% Undaria powder, 2% wasabi leaf, 2% wasabi stem, and 0.5% herb (Obosan) for 8 weeks. Survival was not affected by the different dietary additives (P>0.05). The highest weight gain and feed efficiency offish fed the diet containing 0.5% herb were significantly higher than those of fish fed the diets containing 10% Undaria powder (P<0.05). No significant differences were found in contents of moisture, crude protein, lipid and ash of whole body (P>0.05). Fish fed the diet containing 10% Undaria powder showed the highest moisture and the lowest crude lipid contents in the liver. Although hematological parameters (red blood cell, hematocrit and hemoglobin) and serum constituents (glucose, total cholesterol and glutamic-oxaloacetic transaminase) contents of fish varied between treatments, no specific trend was observed throughout feeding periods. Lysozyme activity in the serum and nitroblue tetrazolium reduction of macrophage in the head kidney from fish fed the diets containing herb was significantly higher than those of fish fed the control diet. The results of this study suggest that herb as an additive in this formulated diet may improve growth and non-specific immune response of juvenile flounder.

Sunlight, and in particular its UV component, is the major environmental trigger that underlies the major signs of human skin and skin cancer in general. Therefore, this study was carried out to investigate the UV protection effects of R. coreanus. R. coreanus was extracted by ultra high pressure extraction process at 500 MPa and $30^{\circ}C$ for 5 and 15 minutes. The cytotoxicity of the extracts extracted by ultra high pressure process on human dermal fibroblast cell CCD-986sk, human kidney normal cell HEK293, and human lung normal cell HEL299 was measured as 17.5%, 16.5% and 14.0%, respectively in adding $1.0\;mg/m{\ell}$ of the samples, which was much lower than that from conventional water extraction method at $100^{\circ}C$ as 23.2%, 22.5%, 21.2%. The secretion of $NO^-$ from macrophage showed $15.9\;{\mu}M$ on the R. coreanus extract from this process, which was higher than others. Prostaglandin $E_2$ ($PGE_2$) production from UV-induced human skin cells was also greatly decreased down to $510\;pg/m{\ell}$, compared to the control. From the results, we considered that the extracts from R. coreanus could be potent natural materials for skin anti-inflammation agent, and could be used as a potential anti-aging for the photo-damaged skin.

1. Definition : Bee-venom therapy does not involve actual bee-stings: it is a treatment method with acquired bee-venom extract through the electric stimulus on the bee, It is injected subcutaneusly on the acupuncture point after refining, according to the diagnosis of constitution and disease. 2. History : Around 2000 B.C., records that Bee-venom was used for therapy were written in the medical book of Babylonia and Papirus of ancient Egypt. Hippocrates, who is called the father of Medicine, said that Bee-venom is Arcanum, which means mysteric medicine. In Oriental medicine, B.C. 200, there was a clinical record that the meat suspended in front of the bee house on the tree in order to get bee-venom, was attached on the lesion. 3. Mechanism of Action : There are two aspects: 1) The effect of stimulating acupunture point It is similar to the chemical moxa. I think that there are several methods of stimulating the acupuncture point： For example, a simple needle is a mechanical stimulus, Moxa is a heating stimulus and electric and Raser acupunture etc. And another stimulus: in the ancient orient, a chemical stimulus called Chungu(Tianjiu), is attached to the lesions by using grinded insects (ex. Mylaris phalerate PALL.) which have toxin. So Bee venom therapy is similar to this. 2) The effect of biochemical ingredients Bee venom consists of 40 kinds of ingredients. For example, me Iii tin, Apamin, Pospholipase A2, MCD peptide, Adolapin and so on. They have effects which have been proven through experimentation l) tonifying mechanism of the body through increasing hormon secretion 2) tonifying immune system through proliferation of WBC, lymphocytes, macrophage 3) anti-inflammatory reaction Therefore Bee venom therapy is the representative 3rd Medicine, which combined East & West medicine. 4. Application of disease : L.B.P and HIVD, O.A, R.A, degenerative arthritis, shoulder pain and other pain diseases. 5. Therapic methods : According to constitution and disease, proper concentration of bee venom is injected on acupunture point, 2 times a week. Generally one term is consisted of 15times. 6. Contraindication : Heart disease, TBc, DM, kidney disease(nephritis), pregnancy, woman in menstruation 3-4 persons per 100,000 persons may have severe allergic reaction.

In recent years, global warming is causing dramatic environmental changes and deterioration, such as hypoxia, leading to reduced survival rate and growth performance of farmed aquatic animals. Hence, understanding systemic immuno-physiological changes in fish under environmental stress might be important to maximize aquaculture production. In this study, we investigated physiological changes in rainbow trout exposed to hypoxic stress by monitoring changes in blood chemistry, leukocyte population, and expression levels of related cytokine genes. Hematological and serological factors were evaluated in blood obtained from rainbow trout sampled at a dissolved level of 4.6 mg O₂ L^-1 and 2.1 mg O₂ L^-1. Blood and head kidney tissue obtained at each sampling time point were used to determine erythrocyte size, leukocyte population, and cytokine gene expression. The level of LDH and GPT in fish under progressive hypoxia were significantly increased in plasma. Likewise, the (Granulocyte + Macrophage)/lymphocyte ratio (%) of fish exposed to hypoxia was significantly lower than that in fish in the control group. Such changes might be due to the rapid movement of lymphocytes in fish exposed to acute hypoxia. In this study, significant up-regulation in expression levels of IL-1β and IL-6 gene appeared to be involved in the redistribution of leukocytes in rainbow trout. This is the first study to demonstrate the involvement of cytokines in leukocyte trafficking in fish exposed to hypoxia. It will help us understand systemic physiological changes and mechanisms involved in teleost under hypoxic stress.

Objectives : The aim of the present study is to examine the effect and mechanism of Erycibae Caulis and Corydalis Tuber Pharmacopuncture (ECP) on a mouse model with collagen induced rheumatoid arthritis (CIA). Methods : We evaluated the Aspartate aminotransferase (AST), Alanine aminotransferase (ALT), Creatinine, and the Blood urea nitrogen (BUN) of serum to examine the safety of this study. In vivo, we compared the results of the non-treated group, the normal saline pharmacopuncture treated control group, the indomethacin treated group and the ECP group. We evaluated rheumatoid arthritis manifestation and the Rheumatoid Arthritis Index (AI). Also, immune cells in blood affected by ECP were evaluated by calculating the level of white blood cells (WBC), neutrophil, lympocytes and monocytes. Next, the level of Immunoglobulin M (IgM), Immunoglobulin G (IgG), Interleukin (IL)-$1{\beta}$, IL-6, IL-17, Tumor Necrosis Factor (TNF)-${\alpha}$ and Granulocyte-macrophage Stimulating Factor (GM-CSF)in serum were measured. We examined the imaging of cartilage degeneration using micro CT-arthrography of the hind paw. Additionally, we examined the effects of reducing bone volume (BV) ratio and bone surface/bone volume (BS/BV) ratio with 3D Micro-CT. Finally, we did a histopathologic examination analysis. Results : The absence of liver and kidney toxicity was evident. In vivo, edema of the joints of the ECP group decreased greatly in macroscopic observation. AI measurement of the ECP group also decreased significantly compared to the control group. The level of WBC, neutrophil, lympocytes, and monocytes in the blood decreased but there was no statistical significance of this data. IgM of the ECP group decreased significantly compared to the control group. IL-$1{\beta}$, IL-6, TNF-${\alpha}$, and GM-CSF production of the ECP group decreased significantly compared to the control group. As a result of examining joint condition with 3D micro CT, deformation and destruction of the joint was shown to have decreased. Bone density of ECP group increased at a statistically significant level compared to the control group. Degree of joint inflammation of ECP group decreased significantly compared to the control group. After H&E and M-T staining, infiltration of immune cells, subsidence of the cartilage, damage to the synovial cells and joint erosion decreased. Conclusion : This study showed that ECP hindered the process of rheumatoid arthritis and protected joints and cartilage.

Background: Cassia tora L., an annual or perennial plant of the Fabaceae family, is traditional medicine with various biological activities, including anti-constipation and, anti-inflammation. Chemical compounds such as anthraquinone glycoside and naphthalene derivatives have been isolated from this plant. Cassia tora L. is a common contaminant of agricultural commodities, but is toxic to cattle and poultry. Methods and Results: To investigate the potential toxicity, Cassia tora L. aqueous extract (CO) was administered orally to rats for 26 weeks at 0 (control), 300, 1,500 and 3,000 mg/kg/day (n = 10 for male rats for each dose). The positive control comprised animals orally administered anthraquinone 100 mg/kg/day. There was no treatment-related mortality. An increase in the kidney weight was observed at 3,000 mg/kg/day of CO and anthraquinone 100 mg/kg/day. Macrophage infiltration in the colon was observed at CO 1,500 and 3,000 mg/kg/day and anthraquinone 100 mg/kg/day, but there were no significant toxicological changes in the incidence and severity of the finding. Conclusions: The oral no-observed-adverse-effect level (NOAEL) of CO was 3,000 mg/kg/day in male rats and no target organs were identified. In addition, 300 mg/kg was found to be the no-observed-effect level (NOEL) for systemic toxicity under the conditions of the study.
