  • The varying characteristics between traditional and commercial soy sauce may be initiated by raw materials and fermentation techniques for the production of $meju$ and $koji$. We examined properties regarding polysaccharides isolated from commercial soy sauce made by the $koji$ process (CSP-0) and Korean traditional soy sauce made by the $meju$ process (KTSP-0) as well as their immuno-stimulating activities. KTSP-0 had rhamnogalacturonan II (RG-II) including 1.1% of unusual monosaccharides 3-deoxy-D-$manno$-2-octulosonic acid (KDO). Anti-complementary activities of CSP-0 and KTSP- 0 were increased dose-dependently but KTSP-0 (64.7%) was higher than CSP-0 (56%) at $1,000{\mu}g/mL$. C3 activation products were identified by crossed immuno-electrophoresis. CSP-0 caused complementary activations $via$ only classical pathway while KTSP-0 caused complementary activations $via$ both alternative and classical pathways. KTSP-0 significantly increased the secretion of interleukin (IL)-6 at $8-1,000{\mu}g/mL$ and IL-12 at $40{\mu}g/mL$ on macrophages. The results suggest that the immuno-stimulating activity of KTSP-0 is greater than that of CSP-0 from anti-complementary activity.

  • As a part of ongoing research to elucidate and characterize antiinflammatory nutraceuticals, the crude extracts from Atriplex gmelinii C. A. Mey. and their solvent-partitioned fractions were tested for their antiinflammatory potential in lipopolysaccharide (LPS)-stimulated RAW 264.7 mouse macrophages. The crude extracts of A. gmelinii C. A. Mey. were fractioned according to polarity with n-hexane, 85% aqueous methanol (85% aq. MeOH), n-butanol, and $H_2O$. Their antiinflammatory activities were investigated in LPS-induced inflammation in mouse macrophages by measuring nitric oxide (NO) generation and mRNA expression of inflammation mediators, namely, inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2), interleukin-$1{\beta}$ ($IL-1{\beta}$), and IL-6. As a result, we confirmed that the crude extracts of A. gmelinii C. A. Mey. inhibited LPS-stimulated NO production and mRNA expression of iNOS and COX-2 as important inflammatory factors. The inhibition of NO production through the downregulation of important inflammatory factors such as iNOS, COX-2, $IL-1{\beta}$, and IL-6 was found by treatment with all solvent-partitioned fractions. Among all tested fractions, 85% aq. MeOH showed the strongest antiinflammatory response. Based on the current results, A. gmelinii C. A. Mey. was suggested to possess natural antiinflammatory components, indicating that it could be used as a valuable source of antiinflammatory substances.

  • In this study, the anti-inflammatory effect of Polyopes affinis ethanol extract (PAEE) was investigated using LPS-stimulated RAW 264.7 cells and a croton oil-induced ICR mice model. Treatment with PAEE significantly reduced production of nitric oxide (NO) and pro-inflammatory cytokines [interleukin (IL)-6, tumor necrosis factor $(TNF)-{\alpha}$, and $IL-1{\beta}$] in lipopolysaccharide (LPS)-stimulated RAW 264.7 cells. PAEE treatment also reduced expression of inducible NO synthase, cyclooxygenase-2, nuclear $factor-{\kappa}B$, and mitogen-activated protein kinases in LPS-stimulated RAW 264.7 cells. In the croton oil-induced ear edema test, application of PAEE (10~250 mg/kg body weight) reduced ear edema in a dose-dependent manner, and PAEE treatment at 50 mg/kg body weight showed similar inhibitory effects compared with prednisolone (10 mg/kg body weight). Histological analysis revealed reduced dermal thickness and lower number of infiltrated mast cells. These results suggest that PAEE might be used as a promising anti-inflammatory agent for inhibition of LPS-induced inflammation and ear edema formation.

  • 5-Aminolevulinic acid phosphate (5-ALA-p) is a substance obtained by eluting 5-ALA (a natural delta amino acid) with aqueous ammonia, adding phosphoric acid to the eluate, and then adding acetone to confer properties suitable for use in photodynamic therapy applications. However, its pharmacological efficacy, including potential mechanisms of antioxidant and anti-inflammatory reactions, remains unclear. This study aimed to investigate the effects of 5-ALA-p on oxidative and inflammatory stresses in lipopolysaccharide (LPS)-stimulated RAW 264.7 cells. Our data showed that 5-ALA-p significantly inhibited excessive phagocytic activity via LPS and attenuated oxidative stress in LPS-treated RAW 264.7 cells. Furthermore, 5-ALA-p improved mitochondrial biogenesis reduced by LPS, suggesting that 5-ALA-p restores mitochondrial damage caused by LPS. Additionally, 5-ALA-p significantly suppressed the release of nitric oxide (NO) and pro-inflammatory cytokines, such as tumor necrosis factor α (TNF-α), interleukin (IL)-1β, and IL-6, which are associated with the inhibition of inducible NO synthase and respective cytokine expression. Furthermore, 5-ALA-p reduced the nuclear translocation of nuclear factor-kappa B (NF-κB) and inhibited phosphorylation of mitogen-activated protein kinases (MAPKs), indicating that the anti-inflammatory effect of 5-ALA-p is mediated through the suppression of NF-κB and MAPK signaling pathways. Based on these results, 5-ALA-p may serve as a potential candidate to reduce inflammation and oxidative stress.

  • Background: Abnormalities of the peripheral blood are frequent and varied in patients with miliary tuberculosis. Anemia, leukopenia, thrombocytopenia, pancytopenia, monocytosis, basophilia, eosinophilia and leukemoid reactions have been reported. These abnormalities are more frequent in patients with positive bone marrow study. In this report, we evaluated clinical, hematological and immunological features in patients with miliary tuberculosis in order to know whether difference is existed between "bone marrow biopsy positive group(pathologically proven to miliary tuberculosis)" and "negative group". Method: Clinical evaluation, serum ADA, sIL-2R, and T-lymphocyte subsets were measured in 40 patients with miliary tuberculosis who received bone marrow biopsy. Results: 1) The average age of patients was 39 year-old. There were 23 male and 17 female patients. Associated extrapulmonary tuberculosis are 9 CNS tuberculosis, 6 joint tuberculosis, and 2 tuberculous pleurisy. 2) Sixteen of the 40 patients were positive bone marrow biopsy(60%). 3) Sixteen of the 40 patients(60%) had anemia(11 positive patients: 13 negative patients). Leukopenia occurred in 12 per cent(4:1). Thrombocytopenia was noted in 10%(3:1). 4) The mean value of serum ADA was 83 U/L(90 U/L: 70.6 U/L, p=0.23). 5) The mean activity of Soluble IL-2 receptor was 4,643 pmol/L($6840{\pm}7446\;pmol/L$: $1,897{\pm}1,663\;pmol/L$, p=0.06). 6) In the T lymphocyte subsets, the percent of T-lymphocytes was 64%(62%:73%, p=0.2). In some patients(9), $T_4$ and $T_8$ ratio in BAL fluid($1.97{\pm}1.2$) was higher than that in the peripheral blood($1.16{\pm}0.5$). Conclusion: Bone marrow examination are diagnostic in 60% of cases of miliary tuberculosis. Percents of the total T lymphocyte and helper T cell in BAL are more elevated than in peripheral blood. There was no significant difference in peripheral blood abnormalities and marker of T lymphocyte activation between the bone marrow biopsy positive and negative group.

  • The biological activities of extracts from Rubus coreanus Miq. were compared. About 70% of the growth of human hepatocarcinoma and 79% of human gastric cancer cell was inhibited in adding 1.0 mg/ml of the extracts of Rubus coreanus Miq. respectively. The growth of human breast cancer cells was also inhibited in adding 1.0 mg/ml of the extracts as well as 78% of the human cancer cells. It was proved that the growth of human normal lung cell, scored as 15% for the extracts. Overall selectivity of the extracts on several human cancer cell line was over 5, which is higher than those from the Rubus coreanus Miq. The growth of both human immune B and T cells was enhanced up to 1.4 to 1.8 times by adding the extracts, compared to the controls. The secretion of tumor necrosis $factor-alpha(TNF-{\alpha})$ from T cell was also increased up to 78.8 pg/ml in adding the ethanol extract (0.5 mg/ml). Ethanol extract also increased up to about 70 pg/ml of interleukin-6(IL-6) from B cell. For screening regulate function of blood pressure, angiotensin converting enzyme(ACE) activity was inhibited up to 25% by adding the ethanol extract (1.0 mg/ml). In testing the hypoglycemic activity, 20% of ${\alpha}-glucosidase$ activity was inhibited for the extracts (0.5 mg/ml). GST activity was increased in the range of 1.2 to 1.6 times by adding extracts.

  • Background: It has been found that Helper T cells in the peripheral blood are decreased in the cell mediated immunity in the pulmonary tuberculosis. But it has not been confirmed yet that only decrease in number of cells which has phenotype in the peripheral blood is defined to decrease in cell mediated immunity. The immunocytochemical study was performed to observe the change of the percentage of T-lymphocytes with their subsets and activated T cells in the peripheral blood of pulmonary tuberculosis and to know how many T cells would be activated, relative to resting cells in the peripheral blood. Methods: The peripheral blood obtained from twenty two patients and ten healthy controls were smeared on the gelatin coated slide glass prepared for of mononuclear cells. The double bridge technique of alkaline phosphatase-antialkaline phosphatase(APAAP) method was used. As the primary antibodies, $T_1$(anti-human T cell), $T_4$(anti-human helper/inducer T cells) and $T_8$(anti-human supressor/cytotoxic T cell) antibodies and interleukin-2 receptor (for early activated T cell), very late activation antigen (for activated cytotoxic T cell), T cell lineage specific activation antigen monoclonal actibodies were used. Results: 1) There were significantly decrease in the absolute number of $T_4$(+) cells but significantly increase of $T_8$(+) cells in the peripheral blood of pulmonary tuberculosis (p<0.05). 2) The percentage of $T_4$(+) cells showed significantly decrease in pulmonary tuberculosis but $T_8$(+)cells significantly increase(p<0.05). $T_4(+)/T_8(+)$ ratio showed significantly decrease in the peripheral blood of the pulmonary tuberculosis(p<0.05). 3) There were significantly increase in the absolute number of variable stages of activated T cells in the peripheral blood of the pulmonary tuberculosis(p<0.05). 4) The percentage of IL-2R, VLA-1, TLiSA were 6.45+1.56%, $7.64+1.34^*$, 10.45+1.16% in order which showed significantly increase in the peripheral blood of the pulmonary tuberculosis(p<0.05). Conclusion: We speculate that only a few percentage of T lymphocyte is activated in cell mediated immunity in pulmonary tuberculosis.

  • Purpose: The rice germ fraction is a better source of protein, lipid, and fiber than the rice endosperm. Furthermore, the rice germ is rich in bioactive phytochemicals such as γ-aminobutyric acid, tocopherols, tocotrienols, phytic acid, and so on. In this study, the phytosterol content and antioxidant activity of Keunnunjami germ (KG) or normal rice germ supplement were investigated in healthy adult rats. Methods: In vitro, quantitative assessment of phytosterols, including β-sitosterol, campesterol, cycloartenol, and stigmasterol, was performed. Comparative antioxidant activities of 2 rice germs were measured based on DPPH radical scavenging activity, reducing power, and ABTS radical scavenging capacity. In vivo, male Spraque-Dawley rats (30-weeks-old) were randomly assigned a diet of normal control (NC, AIN-93M diet), AIN-93M diet supplemented with normal rice germ 3% (NG3), or AIN-93M diet supplemented with KG 3% (KG3) and fed for 8 weeks. Results: KG contained significantly higher campesterol and stigmasterol contents and antioxidant activity than normal rice germ. The KG3 group exhibited significantly lower body weight gain as well as inguinal and total white adipose tissue weights. There were no significant differences in plasma glucose, insulin, C-peptide, or homeostasis model assessment of insulin resistance level among the 3 groups. The plasma tumor necrosis factor-α concentration was significantly lower while leptin, advanced oxidation protein products, and interleukin-6 showed downward trends in the KG3 group. In addition, the superoxide dismutase level of the KG3 group was significantly higher compared to the NC and NG3 groups. Conclusion: This study indicates that KG can be considered as a valuable source of phytosterol components. Lastly, KG has strong antioxidant properties and may have potential to ameliorate elevation of proinflammatory cytokine production with age.

  • Objectives: Chungpaesagan-tang (CPSGT), which is frequently used for treating patients of cerebrovascular disease, has not been reported by clinical doctors concerning the effect of neuronal aptosis caused by brain ischemia. To study the effect of CPSGT on focal cerebral ischemia in normal and diabetic rats and SHR, focal cerebral ischemia was induced by transient MCAO, and after onset CPSGT was administrated. Methods: Rats (Sprague-Dawley) were divided into four groups: sham-operated group, MCA-occluded group, CPSGT­administrated group after MCA occlusion, and normal group. The MCA was occluded by intraluminal method. CPSGT was administrated orally twice (l and 4 hours) after middle cerebral artery occlusion. All groups were sacrificed at 24 hours after the surgery. The brain tissue Was stained with $2\%$ triphenyl tetrazolium chloride (TTC) or $1\%$ cresyl violet solution, to examine effect of CPSGT on ischemic brain tissue. The blood samples were obtained from the heart.~. Tumor necrosis $factor-\alpha$ level and interleukin-6 level of serum was measured from sera using enzyme-linked immunoabsorbent assay (ELISA). Then changes of immunohistochemical expression of $TNF-\alpha$ in ischemic damaged areas were observed. Results: In NC+MCAO+CP and DM+MCAO+CP, CPSGT significantly (p<0.01) decreased the number of neuron cells compared to the control group. CPSGT markedly reduced (p<0.01) the infarct size of the forebrain in distance from the interaural line on cerebral ischemia in diabetic rats. CPSGT significantly reduced the $TNF-\alpha$ expression in penumbra region of damaged hemisphere in diabetic rats. Conclusions: CPSGT had a protective effect on cerebral ischemia in SD rats, especially in diabetic rats compared with normal SD rats.

  • BACKGROUND/OBJECTIVES: The traditional Korean diet is plant-based and rich in antioxidants. Previous studies have investigated the potential health benefits of individual nutrients of Korean foods. However, the cumulative effects of a Korean diet on inflammation remain poorly understood. Therefore, the aim of this study was to investigate the anti-inflammatory effects of a plant-based Korean diet. MATERIALS/METHODS: Using data from the Fifth Korean National Health and Nutrition Examination Survey, 75 individual plant food items were selected which represent over 1% of the total diet intake of the Korean diet. These items were classified into ten different food groups, and the vegetable (Veg) and fruit (Fruit) groups were studied based on their high antioxidant capacity. For comparison, a mixture of all ten groups (Mix) was prepared. To produce a model of inflammation with which to test these Veg, Fruit, and Mix plant-based Korean food extracts (PKE), RAW264.7 macrophages were treated with lipopolysaccharide (LPS). RESULTS: Levels of nitric oxide (NO) and prostaglandin $E_2$ ($PGE_2$), as well as protein expression of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) were found to be lower following PKE treatment. Furthermore, PKE treatment was found to suppress tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$) and interleukin-6 (IL-6) via the nuclear transcription factor kappa-B ($NF-{\kappa}B$) signaling pathway. Overall, the Mix group exhibited the greatest anti-inflammatory effects compared with Veg and Fruit PKE group. CONCLUSIONS: Inhibition of LPS-induced pro-inflammatory mediators by the PKE tested was found to involve an inhibition of NF-kB activation. Moreover, PKE tested have the potential to ameliorate various inflammation-related diseases by limiting the excessive production of pro-inflammatory mediators.
