This study was conducted to investigate feeding effects of the high pressure boiled extracts (HPBE) of the Ogol chicken with herbs on glucose, hormones and immunological response (cytokine, specific antibody) of serum in the rat which fed either with normal feed (T$_1$), normal feed + herb HPBE (T$_2$), normal feed + Ogol chicken HPBE (T$_3$), normal feed + mixture of cross-bred Ogol chicken HPBE (T$_4$) hydrolyzed with Flavourzyme 0.1% for 35 days. During experimental period, there was a weak trend to have a higher glucose content for the T$_4$ group with 102.27${\pm}$5.95 mg/dL, but it was not significantly higher than other treatments. For insulin level, T$_1$ group showed numerically a slightly higher level with 6.79${\pm}$4.64 ${\mu}$IU/mL, but the difference was not significant in statistic term due likely to a large variation in comparison with other treatments. The treatments did not significantly alter testosterone level in rat plasma with 1.09, 1.46, 0.98, 1.13 ng/mL in T$_1$, T$_2$, T$_3$ and T$_4$, respectively. T$_4$ treatment increased the aldosterone level to a significantly (p<0.05) higher level (273.33 ng/dL) than other treatments. The extract treated rat showed a tendency in the cortisol level of lower levels than the control group, particularly, it was significantly (p<0.05) lower in T$_3$ group than other groups. T$_3$ and T$_4$ groups showed higher levels for interlukin-4 (IL-4) and anti-BSA IgG in immune cells and plasma. T$_2$, T$_3$ and T$_4$ treatments showed a slightly higher levels in v-interferon (INF-r) than the control, with a greater effect for T4 treatments. These results suggested that HPBE of the cross-bred Ogol chicken hydrolyzed with Flavourzyme increased immunological activity and decreased the concentration of cortisol and aldosterone hormones.

Purpose: Dendropanax morifera Leveille (DML) exhibits diverse biological and pharmacological activities, including anti-oxidative effect, anti-cancer activity, hepatoprotection, immunological stimulation, and bone regeneration. As part of the identification for novel functions of DML, we investigated the therapeutic effects of DML on diabetes induced by streptozotocine (STZ) treatment. Methods: First, the four extracts including the water extract of leaf (DLW), the ethanol extract of leaf (DLE), the water extract of stem (DSW), and the ethanol extract of stem (DSE) were collected from the leaf and stem of DML using a hot water and ethanol solvent. Alterations in body weight, glucose concentration, insulin level, and pancreatic islet structure were investigated in diabetic mice after treatment with extracts of DML for 2 weeks. Results: Among four extracts, the highest level of total polyphenols and total flavonoids was detected in DLW, while the lowest level of these was measured in DSE. The radical scavenging activity was also higher in DLW than in the other three extracts at the concentration of $25-100{\mu}g/mL$, although this activity was maintained at a constant level in all groups at the concentration of $500{\mu}g/mL$. Based on the results of anti-oxidant activity, DLW and DLE were selected for examination of anti-diabetic effects in a diabetes model. Body weight was gradually decreased in all STZ treated groups compared with the No treated group. However, four STZ/DML treated groups maintained a high level of body weight during 7-14 days, while the STZ/vehicle treated group showed a gradual decrease of body weight during the same period. Also, a significant decrease or increase in the concentration of glucose and insulin in the blood of the diabetes model was detected in a subset of groups, although the highest increase was detected in the STZ/DLE-200 treated group. In addition, the histological structure of pancreatic islet was significantly recovered after treatment with DLW and DLE. Conclusion: These results suggest that DLW and DLE may contribute to attenuation of clinical symptoms of diabetes as well as prevent the destruction of pancreatic ${\beta}$-cells in STZ-induced diabetes mice.
Jeungaektang (JAT) is the herbal formula, has the effect of moistening the dryness by activating lung Qi and by nourishing Yin, has being used for dryness syndromes. Generally the herbal formulae for moistening dryness are used for exogenous or endogenous dryness syndromes. JAT has been clinically used for the treatment of endogenous dryness syndromes. It is composed of Scrophulariae Radix. Rehmanniae Radix and Liriopis Tuber. Recent studies showed that JAT has a protective effect against $CCl_{4}-induced$ hepatotoxicity and anti-inflammatory effects against ear swelling of mouse induced by Crotonis Fructus. However, the effect of JAT on the immunological activity was rarely studied. Therefore, this study evaluated the effects of JAT the regulatory mechanism of nitric oxide (NO) and cytokines in the lipopolysaccharide (LPS)-stimulated RAW 264.7 cells. After the treatment of JAT water extract, cell viability was measured by MTT assay, NO production was monitored by measuring the nitrite content in culture medium. Cyclooxygenase-2 (COX -2) and inducible nitric oxide synthase (iNOS) were determined by immunoblot analysis, and levels of cytokine were analyzed by sandwich immunoassays. Results provided evidence that JAT inhibited the production of nitrite and nitrate ($0.1{\sim}1.0$ mg/ml), iNOS ($0.1{\sim}1.0$ mg/ml), $interleukin-1{\beta}$ ( $0.1{\sim}1.0$ mg/ml) and tumor necrosis $factor-{\alpha}$ ($0.1{\sim}1.0$ mg/ml) in RAW 264.7 cells activated with LPS. Furthermore, JAT inhibited the expression of COX-2 expression and production of prostagladin E2 ($0.1{\sim}1.0$ mg/ml). These findings suggest that JAT can produce anti-inflammatory effect, which may play a role in adjunctive therapy in Gram-negative bacterial infections.
Objectives: This study investigated the anti-osteoarthritic effects of Kyejiinsam-tang (hereinafter referred to KIT) on the monosodium iodoacetate (MIA)-induced osteoarthritis rats. Methods: Anti-oxidative effects of KIT were measured by scavenging activities of DPPH, reactive oxygen species (ROS) and nitric oxide (NO). Scavenging activities of anti-oxidation in lipopolysaccharide (LPS)-treated RAW 264.7 cells were also measured for inhibitory effects against the production of inflammatory mediators (tumor necrosis factor-${\alpha}$, interleukin-$1{\beta}$, interleukin-6). Osteoarthritis was induced in rats by injecting MIA in the knee joint. Rats were divided into a total of 4 groups (n=6). The normal group were not treated at all without inducing osteoarthritis whereas the control group were induced for osteoarthritis by MIA and oral medicated physiological saline per day. The positive comparison group was injected with MIA and after 7 days, 2 mg/kg of Indomethacin. The experimental group was injected with MIA and after 7 days was medicated with 34 mg/kg of KIT. Indomethacin and KIT were orally-medicated for each substance a total of 4 weeks, once per day. Weight-bearing on hind legs was measured every week after MIA injection. At the end of the experiment (5 weeks after MIA injection), micro CT (computed tomography)-arthrography and histopathological examinations on the articular structures of knee joint were performed. The effect on inflammatory cytokines and immunological cells in synovial fluid was measured. Volume of cartilage was measured by micro CT-arthrography. Injury to synovial tissue was measured by H & E (hematoxylin and eosin), Safranin-O immunofluorescence. Results: 1. Cytotoxicity against hFCs was insignificant. 2. KIT showed the potent full term for DPPH. 1. NO was significantly reduced by KIT (at 100, $200{\mu}g/m{\ell}$) and ROS was also reduced, but not significantly, by KIT (at $200{\mu}g/m{\ell}$). 2. IL-6 and IL-$1{\beta}$ were significantly reduced by KIT (at 100, $200{\mu}g/m{\ell}$) and TNF-${\alpha}$ was also reduced, but not significantly, by KIT (at $200{\mu}g/m{\ell}$). 1. In hind legs weight-bearing measurement, level of weight increased. 2. Functions of liver and kidney were not affected. 3. IL-$1{\beta}$ was significantly reduced and TNF-${\alpha}$, IL-6 were also reduced but not significantly. 4. PGE2 (prostaglandin E2), LTB4 (leukotriene B4) were significantly reduced in the KIT group. 5. MMP-9 (matrix metalloproteinase-9), TIMP-1 (tissue inhibitor of metalloproteinases-1) and Osteocalcin were significantly reduced in the KIT group. 6. Destruction of cartilage on micro CT arthrography was reduced but had no significant differences. 7. Histopathologically, injury to synovial membrane of the KIT group was decreased and proteoglycan content of KIT group was increased. Conclusions: According to this study, Kyejiinsam-tang has inhibiting effect on the progression of arthritis in MIA-induced osteoarthritis rat. Kyejiinsam-tang has anti-oxidants and anti-inflammation effects, and is related to inhibiting the activity of inflammatory cytokine and injury of volume in cartilage.
Periodontal diseases occur from the interplay between increased bacterial response and the response of the host immune system over time. Anxiety and depression can impair immunological defense mechanisms, causing accumulation of periodontopathogens and thus exacerbating periodontal disease. We investigated the relationship of anxiety and depression to periodontal diseases in Korean women. In this study, 3,551 women aged ${\geq}19$ years were evaluated based on data from the first year (2010) of the Fifth Korea National Health and Nutrition Examination Survey. The analysis of the factors that caused periodontal diseases revealed that dental floss or interdental toothbrush nonuse behaviors have been shown to increase the risk of periodontal disease (odds ratio [OR], 1.49; 95% confidence interval [CI], 1.14~1.95). After adjusting for conditions such as age, marital status, income, educational level, economic activity, diabetes mellitus, smoking, drinking, and frequencies of toothbrushing and interdental cleaning, we found that anxiety and depression increased the risk of developing periodontal diseases (OR, 1.47; 95% CI, 1.04~2.09). People with anxiety and depression have a higher prevalence of periodontal diseases than people without anxiety and depression. Thus, periodic periodontal care and effective self-care education are needed to manage periodontal diseases.

The objective of the current study was to determine the effects of arabinoxylane and polysaccharide peptide (PSP) on the immune cell functions. Both arabinoxylane and PSP increased plaque forming cell (10-15%) and rosette forming cell (10-30%) formation. Stimulation of macrophage with PSP (18%) and arabinoxylane (22%) resulted in increased phagocytic effects. Both arabinoxylane and PSP induced the tumor suppressive effect in mice injected sarcoma-180 cell intracutaneously. When the mice injected intraperitoneal cavity with sarcoma 180 cells, survival ratio was increased in the mice fed on arabinoxylane and PSP. The ratio of PCA was slightly decreased in the mice fed on PSP, especially fed on arabinoxylane than in the control mice. The concentrations of blood histamine were slightly decreased in the mice fed on arabinoxylane and PSP. These results suggest that the capacity of arabinoxylane and PSP seems to act as a potent immunomodulator causing augmentation of immune cell activity, and with the absence of notable side-effects, arabinoxylane and PSP could be used as a biological response modifier having possible therapeutic effects against immunological disorders.

The objective of the current study was to determine the effects of arabinoxylane and PSP on mouse splenocytes, T cells, B cells and macrophages in vitro. Arabinoxylane and PSP directly induced the proliferation of spleen cells in a dose-dependent manner and increased IFN-${\gamma}$ synthesis. Especially, PSP induced IL-2, IL-4 and IL-10 production, Both arabinoxylane and PSP increased PFC (plaque forming cell) and RFC (rosette forming cell) formation. Arabinoxylane was not induced the proliferation of T cells, but PSP directly induced the proliferation of T cells in a high dose. Arabinoxylane and PSP increased the proliferation of B cells and the phagocytic effects of macrophage. When arabinoxylane and PSP were used in macrophage cell line stimulation, there was a marked induction of NO synthesis in a dose-dependent and an increased TNF-$\alpha$ and IL-6 synthesis. Especially, PSP also induced IL-1$\beta$ production. When arabinoxylane and PSP treated in macrophage cell line, there was induction of MHC class II expression. These results suggest that the capacity of arabinoxylane andPSP seem to act as a potent immunomodulator causing augmentation of immune cell activity, and with the absence of notable side-effects, arabinoxylane and PSP could be used as a biological response modifier having possible therapeutic effects against immunological disorders.

The objective of the current study was to determine the effects of the extracts isolated from the fruit body of Flammulina velutipes cultivated with oriental herbal plants on mouse splenocytes, B cells, and macrophages in vitro. The ethanol extracts B (EEB) directly induced the proliferation of spleen cells in a dose-dependent manner and increased IL-6, TNF-${\alpha}$, and IFN-${\gamma}$ synthesis. The EEB also increased the proliferation of B cells in a dose-dependent manner. The production of immunoglobulin M, G1, G2a, G2b, and IgG3 in the presence of the EEB increased progressively in the culture supernatant. When the EEB were used in macrophage cell line (RAW264.7) stimulation, there was a marked induction of NO synthesis in a dose-dependent manner and an increased IL-6, TNF-${\alpha}$, and GM-CSF synthesis. Intraperitoneal injection with EBB showed life prolongation effect of 16.1% in mice previously inoculated with sarcoma-180, respectively. These results suggest that the capacity of the EEB isolated from the fruit body of Flammulina velutipes cultivated with oriental herbal plants seems to act as a potent immunomodulator causing augmentation of immune cell activity, and with the absence of notable side-effects, Flammulina velutipes EEB could be used as a biological response modifier having possible therapeutic effects against immunological disorders. This study also showed that functional components of Flammulina velutipes were possibly improved by incorporating oriental herbal plants in a growth medium.

Solanum Iyratum Thunb (Solanaceae) has multiple applications in korean traditional medicine because of its cytotoxic, immunological and anti-inflammatory activities. However, no study on the anti-arthritic activity of Solanum Iyratum Thunb has been reported in vivo. Rheumatoid arthritis (RA) is a systemic autoimmune disease with chronic inflammation characterized by hyperplasia of synovial cells in affected joints, which ultimately leads to the destruction of cartilage and bone. Cytokine production were assessed during CIA(collagen-induced arthritis) model mice in lymph node (LN), in knee joint and spleen, using ELISA. DBA/1j mice were immunized with bovine type II collagen. After a second collagen immunization, mice were treated with Solanum Iyratum Thunb (SLT) orally at 400, 200 mg/kg once a day for 4 weeks. The severity of arthritis within the knee joints was evaluated by histological assessment of cartilage destruction and pannus formation. SLT significantly suppressed the progression of CIA and inhibited the production of TNF-alpha and IFN-gamma in serum and spleen cell culture supernatant. The erosion of cartilage was dramatically reduced in mouse knees after treatment with SLT. In conclusion, our results demonstrates that SLT significantly suppressed the progression of CIA. This action was characterized by suppression of arthritis index, cartilage erosion and synovial cell infiltration and the decreased production of $TNF-{\alpha}$, $IFN-{\gamma}$, CD4+, CD19+, CD3+/CD69+ cells (in lymph node), CD11b+/Gr-1 + (in knee joint).

The objective of this study was to evaluate the skin inflammation effects of three herb mixture extracts, Ligularia fischeri, Solidago virga-aurea and Aruncus dioicus, which are from Ullung island in Korea. Regulatory mechanisms of cytokines and nitric oxide (NO) are involved in the immunological activity of Raw 264.7 cells. Tested cells were pretreated with 70% acetone extracts of Ligularia fischeri, Solidago virga-aurea and Aruncus dioicus (LSA-A) and further cultured for an appropriated time after lipopolyssacharide (LPS) addition. During the entire experimental period, 1, 10, and 100 ${\mu}g/ml$ of LSA-A had no cytotoxicity. In these concentrations, LSA-A inhibited the production of NO and prostaglandin $E_2$ ($PGE_2$), tumor necorsis factor-a (TNF-a), interleukin-1${\beta}$ (IL-1${\beta}$), interleukin-6 (IL-6) expression of inducible NO synthase (iNOS), and cyclooxygenase-2 (COX-2). LSA-A showed a 60% $PGE_2$ inhibition rate at 100 ${\mu}g/ml$. iNOS and COX-2 inhibition activities were 54%, and 65% at 100 ${\mu}g/ml$, respectively. In addition, LSA-A extract reduced the release of inflammatory cytokines including TNF-a, IL-1${\beta}$ and IL-6. These results suggest that LSA-A may have significant effects on inflammatory factors, and may be a potential anti-inflammatory therapeutic agent.
