  • Objective : Morus alba Linne Root Bark (MRAL) is a medicinal herb in Korean Medicine, known for its anti-inflammatory and anti-allergic properties. However, its mechanisms of action and the cellular targets have not yet been found and the study was developed to investigate the allergic suppressive effect of MRAL. The purpose of this study is to investigate the allergic suppressive effects of MRAL on activation of MC/9 mast cells. Methods : Cytotoxic activity of MRAL (50, 100, 200, 400 ${\mu}g/mL$) on MC/9 mast cells measured using EZ-Cytox cell viability assay kit (WST reagent). The levels of interleukin-5 (IL-5), IL-13 and IL-4, IL-5, IL-6, IL-13 mRNA expression were measured by enzyme-linked immunosorbent assay (ELISA) and real-time PCR respectively. The expression of transcription factors such as GATA-1, GATA-2, NFAT, AP-1 and NF-${\kappa}B$ p65 DNA binding activity were measured by western blot and electrophoresis mobility shift assay (EMSA). Results : Our results indicated that MRAL (50 ${\mu}g/mL$, 100 ${\mu}g/mL$) significantly inhibited PMA/Ionomycin-induced production of IL-5 and IL-13 and the expression of IL-4, IL-5, IL-6 and IL-13 mRNA in MC/9 mast cells. Moreover, MRAL (50 ${\mu}g/mL$, 100 ${\mu}g/mL$) inhibited PMA/Ionomycin-induced GATA-1, GATA-2, NFAT-1, NFAT-2, c-Fos protein expression and NF-${\kappa}B$ p65 DNA binding activity in MC/9 mast cells. Conclusions : In conclusion, we suspect the anti-allergenic activities of MRAL, may be related to the regulation of transcription factors GATA-1, GATA-2, NFAT-1, NFAT-2, c-Fos and NF-${\kappa}B$ p65 DNA binding assay causing inhibition of Th2 cytokines IL-5 and IL-13 in mast cells.

  • Objectives : Smilacis Glabrae Rhizoma (SGR) has been used in traditional medicine for treating diseases related to inflammation and cancer. However, the protective effect of SGR has not been reported in the study of acute pancreatitis (AP). Therefore, this study was performed to evaluate the protective effects of SGR water extract on cerulein-induced AP. Methods : AP was induced by intraperitoneal injection of supramaximal concentrations of stable cholecystokinin analogue cerulein ($50{\mu}g/kg$) 6 times at intervals of one hour in mice. SGR water extract (0.01, 0.05, or 0.1 g/kg) was administrated intraperitoneally 1 h prior to the first injection of cerulein. The mice were sacrificed at 6 h after the final injection of cerulein. Pancreas and lung were rapidly removed for histochemical examination and myeloperoxidase (MPO) assay. In addition, polymerase chain reaction (PCR) was performed to examine mRNA levels of proinflammatory cytokines such as interleukin(IL)-6, $IL-1{\beta}$ and Tumor necrosis $factor(TNF)-{\alpha}$. Results : Administration of SGR water extract significantly inhibited pancreatic weight to body weight ratio. In addition, SGR treatment inhibited the histological damages and increase of MPO activity in both pancreas and lung during AP. Also, mRNA levels of IL-6 but not $IL-1{\beta}$and $TNF-{\alpha}$ were inhibited by SGR water extract against AP. Conclusion : Our results revealed that pre-treatment of SGR water extract reduces the severity of cerulein-induced AP. Therefore, this study suggest that SGR could be used as a drug or agent to prevent AP.

  • Objectives : Hyeonggaeyeongyotang Gagambang (HYT) is a herbal medicine prescribed for the treatment of inflammatory diseases, but it is necessary to study the exact therapeutic efficacy. This study aims to investigate the antibacterial and anti-inflmmatory activities of HYT. Methods : Antibacterial activity of HYT was confirmed by staining Escherichia coli, a gram negative strain, and Staphylococcus aureus, a gram positive strain, on solid Lysogeny Broth (LB) medium containing HYT. Antioxidant activity of HYT was confirmed by 2,2'-azino-bis-3-ethylbenzothiazoline-6-sulphonic acid (ABTS) assay. The phosphorylation of nuclear factor of kappa light polypeptide gene enhancer in B-cells inhibitor, alpha ($I{\kappa}B{\alpha}$) after lipopolysaccharide (LPS) treatment with HYT-treated RAW 264.7 mouse macrophages cells was confirmed by immunoblot analysis and the level of interleukin 1 beta (IL-$1{\beta}$) mRNA expression level was confirmed by quantitative real-time PCR. Results : HYT showed a concentration-dependent antibacterial activity against Escherichia coli and Staphylococcus aureus and also showed excellent antioxidant activity. HYT treatment attenuated the phosphorylation of $I{\kappa}B{\alpha}$induced by LPS treatment in RAW 264.7 mouse macrophages cells. The phosphorylation of $I{\kappa}B{\alpha}$is crucial for the regulation of the expression of various pro-inflammatory cytokines. In addition, IL-$1{\beta}$ mRNA expression level of RAW 264.7 mouse macrophages cells stimulated by LPS treatment was also inhibited by HYT treatment. Conclusions : Through experimental demonstration of the antioxidative, antimicrobial and anti-inflammatory effects of HYT, we demonstrated that HYT is a herbal medicine effective for the treatment of inflammatory diseases caused by various bacterial infections.

  • Objectives The anti-inflammatory and anti-arthritic effects of Youngseonjeatonguem (靈仙除痛飮, YSJTU) was evaluated in a cellular model using RAW264.7 macrophages, which are involved in osteoarthritis (OA), and an animal model using Sprague-Dawley (SD) rats, and a possible mechanism of anti-arthritic actions of YSJTU was presented. Methods RAW264.7 macrophages were activated by lipopolysaccharide (LPS). The production of pro-inflammatory cytokines (tumor necrosis factor [TNF]-𝛼, interleukin [IL]-1𝛽, and IL-6) and inflammatory mediators (nitric oxide [NO] and prostaglandin E2 [PGE2]) was determined by ELISA and Griess assay, respectively. Western blot was performed to determine inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) expression. OA was induced by intra-articular injection of monosodium iodoacetate (MIA) into the right knee joint of SD rats. Results In RAW264.7 macrophages, YSJTU reduced LPS-induced production of TNF-𝛼, IL-1𝛽, and IL-6. In addition, YSJTU inhibited LPS-induced production of NO and PGE2 by suppressing iNOS and COX-2 expression. In SD rats, YSJTU improved MIA-induced OA by reducing swelling, skin heat, and cartilage degradation. In addition, YSJTU reduced serum levels of TNF-𝛼, IL-1𝛽, and IL-6, along with its significant decrease in serum levels of NO and PGE2. Conclusions These results suggest that YSJTU may exert anti-arthritic effect, at least in part, by inhibiting macrophage-mediated joint inflammation.

  • BACKGROUND/OBJECTIVES: Onion, particularly onion peel, is a quercetin-rich food with, anti-inflammatory and immunomodulatory effects. However, the effect of onion peel extract (OPE) in humans is unclear. Thus, the present study aimed to investigate whether OPE improves natural killer (NK) cell activity and cytokine concentration in a randomized double-blind placebo-controlled trial. SUBJECTS/METHODS: Eighty participants aged 19-64 yrs old with a white blood cell count of 4,000-10,000 cells/µL, symptoms of upper respiratory infection at least once within the previous 12 mon, and perceived stress scale (PSS) over 14 were included. Participants were randomly assigned to take either 1,000 mg/day OPE or a placebo for 8 weeks. RESULTS: Compliance were 87.4 ± 8.6% and 86.9 ± 79.0% in OPE and placebo groups. Compared to the placebo, OPE supplementation improved "Hoarseness" (P = 0.038) of the Wisconsin Upper Respiratory Symptom Survey (WURSS)-21 symptom, and stress scores (P = 0.001; 0.021) of PSS. Supplementation of OPE had no significant effect on NK cell activity and concentrations of cytokines such as interleukin (IL)-2, IL-6, IL-12, IL-1β, interferon-γ, and tumor necrosis factor-α. At baseline, the WURSS-21 symptom and PSS score (P = 0.024; 0.026) were higher in the OPE group than the placebo group. Among participants with higher than median WURSS-21 symptom score, OPE supplementation increased NK cell activity (P = 0.038). Supplementation of OPE had no significant effects on safety measurements and adverse events. CONCLUSIONS: The present study suggested that OPE supplementation improves NK cell activity in participants with moderate upper respiratory symptoms without any significant adverse effects.

  • Hot water-extracts prepared from Cordyceps militaris of silkworm pupa (CMP) or Cordyceps militaris of silkworm larva (CML) were tested for tumor growth inhibitory and immunomodulatory activities in ICR mice bearing sarcoma-180 cells solid tumor, and compared with those of the known compound, cordycepin, found in Cordyceps militaris. Mice were subcutaneously injected with sarcoma-180 cells, and i.p. injected with either saline (Control), 50 mg/kg or 100 mg/kg of CMP (CMP50 or CMP100, respectively), or CML (CML50 or CML100, respectively), or 1 or 2 mg/kg of cordycepin (C1 or C2, respectively) for 10 days. Mice injected with CMP50 or CMP100 showed a 47.3% or 57.6% inhibition in the solid tumor growth (P<0.05), while those injected with CML50 or CML100 exhibited a 35.5% or 37.1% reduction (p<0.05) in solid tumor size compared to the value for control mice treated with saline. Animals injected with corcycepin showed a 26∼30% inhibition in the solid tumor growth (P<0.05). Mice bearing solid tumor and injected with CMP or CML showed a significantly increased thymus weight (38∼44% increase), lymphocyte percentages of CD4+ T-cell, CD8+ T-cell, and NK-cell (63∼110% increase) in the spleen, and interleukin-2 excretion (33∼51% increase) by the isolated splenocytes compared to those in control mice (p<0.05). These results indicate that the anti-tumor activity of hot water extracts of Cordyceps militaris, raised on both silkworm pupa and silkworm larva, appears to be associated with their immunomodulatory activity, and these activities found in Cordyceps militaris are superior to those for the single compound, cordycepin.

  • Background: We aimed to investigate mucosal immunity related to forkhead box P3 ($FOXP3^+$) regulatory T (Treg) cells, T helper 17 (Th17) cells and cytokines in pediatric inflammatory bowel disease (IBD). Methods: Mucosal tissues from terminal ileum and colon and serum samples were collected from twelve children with IBD and seven control children. Immunohistochemical staining was done using anti-human FOXP3 and anti-$ROR{\gamma}t$ antibodies. Serum levels of cytokines were analyzed using a multiplex assay covering interleukin $(IL)-1{\beta}$, IL-4, IL-6, IL-10, IL-17A/F, IL-21, IL-22, IL-23, IL-25, IL-31, IL-33, interferon $(IFN)-{\gamma}$, soluble CD40L, and tumor necrosis factor-${\alpha}$. Results: $FOXP3^+$ Treg cells in the lamina propria (LP) of terminal ileum of patients with Crohn's disease were significantly (P < 0.05) higher than those in the healthy controls. $ROR{\gamma}t^+$ T cells of terminal ileum tended to be higher in Crohn's disease than those in the control. In the multiplex assay, serum concentrations (pg/mL) of IL-4 ($9.6{\pm}1.5$ vs. $12.7{\pm}3.0$), IL-21 ($14.9{\pm}1.5$ vs. $26.4{\pm}9.1$), IL-33 ($14.3{\pm}0.9$ vs. $19.1{\pm}5.3$), and $IFN-{\gamma}$ ($15.2{\pm}5.9$ vs. $50.2{\pm}42.4$) were significantly lower in Crohn's disease than those in the control group. However, serum concentration of IL-6 ($119.1{\pm}79.6$ vs. $52.9{\pm}39.1$) was higher in Crohn's disease than that in the control. Serum concentrations of IL-17A ($64.2{\pm}17.2$ vs. $28.3{\pm}10.0$) and IL-22 ($37.5{\pm}8.8$ vs. $27.2{\pm}3.7$) were significantly higher in ulcerative colitis than those in Crohn's disease. Conclusion: Mucosal immunity analysis showed increased $FOXP3^+$ T reg cells in the LP with Crohn's disease while Th17 cell polarizing and signature cytokines were decreased in the serum samples of Crohn's disease but increased in ulcerative colitis.

  • Background: With open heart surgery(OHS), it has been recognized that many postoperative complications and postperfusion syndrome are associated with the activations of complements and leulocytes. Recently, some investigators also demonstrated that interlukin-6(IL-6) linked highly with postperfusion syndrome. The puropose of this study was to investigate the sequential changes of the IL-6 and to clarify each IL-6 relationship to the complements(C3, C4) and inflammatory response following cardiopulmonary bypass(CPB). Material and Method: To determine serum levels of IL-6, complements, leukocytes, and biochemistric markers of liver and renal function, blood samples were taken from th radial artery in 30 adult patients undergoing OHS with CPB. Result: Serum IL-6 levels incrased significantly at 10 minutes after CPB-on(CPB-10) in comparison with the control levels and reached the peak at CPB-off(p<0.05). Serum complement levels declined rapidly at CPB-10 and remained at the lower levels during CPB(p<0.01). Sequential changes of IL-6 levels had positive correlations with the changes of total leukocytes and neutrophil fractions(p<0.05), but had negative correlations with lymphocyte fractions(p<0.05). Changes of C3 related postively to monocyte fractions(p<0.05). Postoperative levels of total protein and albumin, decreased significantly in comparison with the control levels(p<0.01), while the postoperative levels of AST(aspartate transaminase) and bilirubin increased (p<0.01). At CPB-off, IL-6 levels had negative correlations with total protein and albumin levels(r=-0.60, -0.47 respectively, p<0.05), whereas C3 levels had positive correlations with albumin levels(r=0.40, p<0.05). IL-6 levels, as well as neutrophil fractions, had positive correlations with aortic clamp time(ACT) and total bypass time(TBT) (IL-6; r=0.82, 0.79 respectively, neutrophil fractions; r=0.50, 0.56 respectively, p<0.05), wheres lymphocyte frations and albumin levels had negative correlations whith ACT and TBT(lymphocyte fractions; r=-0.52, -0.58 respectively, albumin; r=-0.58, -0.55 respectively, p<0.05). Conclusion: These data showed that elevated production of serum IL-6 during CPB may play a pivotal role in systemic inflammatory responses and prologed CPB period may be assosiated with more sever postperfusion syndromes.

  • Objective: The study was conducted to evaluate the effects of the absorbent (a mixture of activated carbon and hydrated sodium calcium aluminosilicate) on growth performance, blood profiles and hepatic genes expression in broilers fed diets naturally contaminated with aflatoxin. Methods: A total of 1,200 one-day-old male chicks were randomly assigned to 6 treatments with 10 replicate cages per treatment. The dietary treatments were as follows: i) control (basal diets); ii) 50% contaminated corn; iii) 100% contaminated corn; iv) control+1% adsorbent; v) 50% contaminated corn+1% absorbent; vi) 100% contaminated corn+1% absorbent. Results: During d 1 to 21, feeding contaminated diets reduced (p<0.05) body weight (BW), average daily gain (ADG), and average daily feed intake (ADFI), but increased (p<0.05) feed-to-gain ratio (F/G). The absorbent supplementation increased (p<0.05) BW, ADG, and ADFI. There were interactions (p<0.05) in BW, ADG, and ADFI between contaminated corn and absorbent. Overall, birds fed 100% contaminated diets had lower (p<0.05) final BW and ADG, but higher (p<0.05) F/G compared to those fed control diets. The absorbent addition increased (p<0.05) serum albumin concentration on d 14 and 28 and total protein (TP) level on d 28, decreased (p<0.05) alanine transaminase activity on d 14 and activities of aspartate aminotransferase and alkaline phosphatase on d 28. Feeding contaminated diets reduced (p<0.05) hepatic TP content on d 28 and 42. The contaminated diets upregulated (p<0.05) expression of interleukin-6, catalase (CAT), and superoxide dismutase (SOD), but downregulated (p<0.05) glutathione S-transferase (GST) expression in liver. The absorbent supplementation increased (p<0.05) interleukin-1β, CAT, SOD, cytochrome P450 1A1 and GST expression in liver. There were interactions (p<0.05) in the expression of hepatic CAT, SOD, and GST between contaminated corn and absorbent. Conclusion: The results suggest that the naturally aflatoxin-contaminated corn depressed growth performance, while the adsorbent could partially attenuate the adverse effects of aflatoxin on growth performance, blood profiles and hepatic genes expression in broilers.

  • Objective: This study was conducted to determine the effects of stale maize on growth performance, immunity, intestinal morphology, and antioxidant capacity in broilers. Methods: A total of 800 one-day-old male Arbor Acres broilers (45.4±0.5 g) were blocked based on body weight, and then allocated randomly to 2 treatments with 20 cages per treatment and 20 broilers per cage in this 6-week experiment. Dietary treatments included a basal diet and diets with 100% of control maize replaced by stale maize. Results: The content of fat acidity value was higher (p<0.05) while the starch, activities of catalase and peroxidase were lower (p<0.05) than the control maize. Feeding stale maize diets reduced (p<0.05) average daily feed intake (ADFI) throughout the experiment, feed conversion ratio (FCR) during d 0 to 21 and the whole experiment as well as relative weight of liver, spleen, bursa of Fabricius and thymus (p<0.05) on d 21. Feeding stale maize diets decreased jejunum villus height (VH) and VH/crypt depth (CD) (p<0.05) on d 21 and 42 as well as ileum VH/CD on d 42. The levels of immunoglobulin G, acid α-naphthylacetate esterase positive ratios and lymphocyte proliferation on d 21 and 42 as well as lysozyme activity and avian influenza antibody H5N1 titer on d 21 decreased (p<0.05) by the stale maize. Feeding stale maize diets reduced (p<0.05) serum interferon-γ, tumor necrosis factor-α, interleukin-2 on d 21 and interleukin-6 on d 21 and 42. Broilers fed stale maize diets had lower levels of (p<0.05) total antioxidative capacity on d 42, superoxide dismutase and glutathione peroxidase on d 21 and 42, but higher (p<0.05) levels of malondialdehyde on d 21 and 42. Conclusion: Feeding 100% stale maize decreased ADFI and FCR, caused adverse effects on immunity and antioxidant function and altered intestinal morphology in broilers.
