Purpose: The purpose of this study was to compare and quantify the expression of C-reactive protein (CRP), matrix metalloproteinase (MMP)-14, and tissue inhibitor of metalioproteinases (TIMP)-2 in gingival tissues of patients with chronic periodontitis accompanied with inflammatory reaction related to alveolar bone resorption with or without type 2 diabetes mellitus (DM). Methods: Twelve patients with type 2 DM and chronic periodontitis (group 3), twelve patients with chronic periodontitis (group 2), and twelve healthy individuals (group 1) were included in the study. Gingival tissue biopsies were collected from each patient and from healthy individuals at the time of periodontal surgery (including surgical crown lengthening) or tooth extraction. The concentrations of cytokines were determined by a western blot analysis. Results: The expression levels of CRP and MMP-14 increased in group 2 and 3, and they were highest in group 3. The expressions of TIMP-2 also increased in group 2 and 3. Conclusions: This study demonstrated that the expression levels of CRP, MMP-14, and TIMP-2 might be inflammatory markers in periodontal inflamed tissue. It can be assumed that CRP, MMP-14, and TIMP-2 may be partly involved in the progression of periodontal inflammation associated to type 2 DM.

Objectives This study investigated the effects of Cheongyeonsan for allergic rhinitis. Methods First, the GS/MS was used to analyze the effects of Cheongyeonsan by measuring inflammatory markers. Second, 3 groups of 10 6-week-old BALB/c mice were divided into Ctrl (no treatment), ARE (allergic rhinitis-induced without treatment), and CRT (allergic rhinitis-induced after Cheongyeonsan treatment) groups. Ovalbumin (OVA) was used as an antigen to induce allergic rhinitis and sensitization was performed by intraperitoneal injection of 0.1% OVA solution 21, 14, and 7 days before the onset of allergic rhinitis. Allergic rhinitis was induced by dropping OVA solution on the nasal cavity of each mouse for 5 days after the last sensitization. Seven days after the first induction, second induction was introduced by the same method. After making the section, MMP-9, substance P, $TNF-{\alpha}$, $NF-{\kappa}B$ p65, COX-2, iNOS and Nrf, apoptotic cells were observed by Masson trichrome staining, immunohistochemical staining, TUNEL of nasal mucosal tissues of each group. Results GC/MS results showed undecanoic acid. Masson trichrome results showed that the CRT group had less respiratory epithelial damage. Immunohistochemical staining showed CRT group had 58% decrease in MMP-9, 61% decrease in substance P, 55% decrease in $TNF-{\alpha}$, 38% decrease in $NF-{\kappa}B$ p65, 53% decrease in COX-2, 54% decrease in iNOS, 87% increase in Nrf compared to those of the ARE group. TUNEL showed a positive reaction of 84% increase in apoptotic cells greater than that of the ARE group. Conclusions Cheongyeonsan alleviates nasal mucosal damage and reduces inflammatory mediators from allergic rhinitis-induced mice.

Objectives : In this study, we investigate the anti-allergic effects of Ullmus macrocarpa Hance (Ulmus) on RBL-2H3 mast cell (basophilic leukemia cell line), which are mediated by FcεRIs. Methods : We evaluated the effect of the ethanol extract of Ulmus on the allergic inflammatory response in IgE-antigen-mediated RBL-2H3 cells. Cell toxicity was determined by MTT assay and the markers of degranulation such as beta-hexosaminidase, histamine, PGD2, TNF-α, IL-4, IL-6 production of inflammatory mediators and FcεRI-mediated protein expression by western blot. Results : Ulmus inhibited degranulation and production of allergic mediators (e.g., TNF-α, IL-4, and IL-6) in them. Ulmus reduced histamine levels, expression of FcεRI signaling-related genes such as Lyn, Syk, and Fyn, and extracellular signal-regulated kinase phosphorylation in mast cells. Also, Ulmus reduced PGD2 release and cyclooxygenase-2 expression, and cytosolic phospholipase A2 phosphorylation in FcεRI-mediated RBL-2H3 mast cells. Conclusions : These results indicate that Ulmus exhibits anti-allergic activity through inhibition of degranulation and inflammatory mediators and cytokine release. These findings suggest that Ulmus may have potential as a prophylactic and therapeutic agent for the treatment of various allergic diseases.

Background: Gintonin-enriched fraction (GEF) is a new non-saponin component glycolipoprotein isolated from ginseng root. This study examined the effect of GEF on age-related sarcopenia in old C57BL/6J mice. Methods: Young (3-6 months) and old (20-24 months) C57BL/6J mice received oral GEF (50 mg/kg/day or 150 mg/kg/day) daily for 5 weeks. During the oral administration period, body weight and grip strength were measured weekly. After sacrifice, muscles from the hindlimb were excised and used for hematoxylin and eosin staining and western blotting to determine the effects of GEF on sarcopenia. The thymus was photographed to compare size, and flow cytometry was performed to examine the effect of GEF on immune homeostasis in the thymus and spleen. Blood samples were collected, and the concentrations of pro-inflammatory cytokines and IGF-1 were measured. Results: GEF caused a significant increase in muscle strength, mass, and fiber size in old mice. GEF restored age-related disruption of immune homeostasis by maintaining T cell compartments and regulating inflammatory biomarkers. Thus, GEF reduced common low-grade chronic inflammatory parameters, which are the main cause of muscle loss. Conclusion: GEF maintained immune homeostasis and inhibited markers of chronic inflammation, resulting in anti-sarcopenia effects in aged C57BL/6J mice. Thus, GEF is a potential therapeutic agent that slows sarcopenia in the elderly.

In this study, the anti-inflammation efficacy of Lactobacillus johnsonii derived from Kimchi was investigated. Raw 264.7 cells, which are rat-derived macrophages, were treated with Lactobacillus johnsonii lysate to confirm the expression level of TNFα and IL1β, which are inflammatory markers, and when treating 250 ㎍/mL extract, the expression level of TNFα and IL1β decreased by 40.55% and 34.66% compared to the control group treated with 1 ㎍/mL LP, respectively. In addition, as a result of confirming the transcriptional activity of NF-κB, a key transcription factor in cytokine expression by LPS, it was confirmed that the transcriptional activity of NF-κB was 40.76% inhibited compared to the control group treated with 1 ㎍/mL LPS. Therefore, the results of this study confirmed that Lactobacillus johnsonii lysate is likely to be an anti-inflammatory or skin-soothing functional material by preventing the expression of cytokine by LPS and controlling NF-κB transcriptional activity.

Objective: The aim of this study was to identify the efficacy and underlying mechanism of cloves as an osteoarthritis (OA) treatment in a monosodium iodoacetate (MIA)-induced rat OA model. Osteoarthritis (OA) is nowadays one of the most prevalent degenerative joint diseases. Methods: Sprague-Dawley rats treated with MIA (50 μL; 80 mg/mL) were used as in vivo OA models. Cloves (100 and 200 mg/kg b.w.) were administered orally once daily for 2 weeks from 7 days after MIA injection. Changes in hindpaw weight distribution (HWD) were measured as a joint discomfort index. Activation markers related to inflammatory responses and cartilage degeneration in the right knee joints were evaluated by serum analysis and western blotting. Results: HWD decreased in the MIA control group but showed a dose-dependent elevation after clove treatment. Clove treatment inhibited inflammatory factors by PI3K/Akt/NF-κB signaling pathways, while also activating antioxidant factors through Sirt1/AMPK signaling pathways. Clove treatment also suppressed matrix metalloproteinase (MMP) overexpression and significantly increased the levels of tissue inhibitors of metalloproteinases (TIMPs). Conclusions: Treatment with cloves effectively reversed MIA-induced effects. Therefore, clove treatment could have the potential to protect against or treat OA.

Objectives The aim of this study was to identify the effect of Baekho-tang extract on epidermal barrier recovery and inflammation relief in atopic dermatitis-induced mice through Endocanabinoid system (ECS) regulation. Methods In this study, we used 4-week-old NC/Nga mice were divided into 4 group: lipid barrier elimination group (LBEG), palmitoylethanolamide treated group after lipid barrier elimination (PEAT), Baekho-tang extract treatment group after lipid barrier elimination (BHTT) and control group (Ctrl). Each group was assigned 10 animals. We identified that cannabinoid receptor (CB) 1, CB2, CD (Cluster of Differentiation) 68, inducible nitric oxide synthase (iNOS), substance P and Matrix metallopeptidase 9 (MMP-9) through our immunohistochemistry. Results We discovered that when compared to PEAT, 8-hydroxydeoxyguanosine, a marker of oxidative stress in the epidermal barrier, and CB1 and CB2, markers of ECS modulation, were less activated in BHTT. These results led to an anti-inflammatory response in BHTT, with a significant decrease in several inflammatory mediators such as CD 68, iNOS, substance P and MMP-9 compared to PEAT and LBEG. Conclusions These results suggest that the Baekho-tang extract can reduce the inflammation of atopic dermatitis by restoring the structural damage of the skin lipid barrier through ECS modulation.

Background: Canine parvoviral enteritis (CPE) is a fatal disease worldwide. The treatment of CPE is based mainly on supportive and symptomatic treatment. Antiviral addition to the treatment may result in a higher survival. Objectives: This study evaluated the effects of antiviral treatments with a standardized treatment (ST) on the clinical and inflammatory response of dogs with naturally occurring CPE. Methods: Twenty-eight dogs with CPE caused by canine parvovirus type 2 were divided randomly into treatment groups. The ST group received fluid, antibiotic, antiemetic, and deworming treatments. The antiviral treatment groups received the same ST with an additional antiviral drug, recombinant feline interferon omega (rFeIFN-ω), oseltamivir (OSEL) or famciclovir (FAM). Results: Compared to the healthy control, the tumor necrosis factor-α, interleukin-1β, interferon (IFN)-α, IFN-γ, haptoglobin, and C-reactive protein values were high (p < 0.05) on day zero. At presentation, mild lymphopenia, neutropenia, and a high neutrophil to lymphocyte (LYM) ratio (NLR) were also observed. Adding rFeIFN-ω to the ST produced the best improvement in the clinical score with a decreased NLR, while leucocytes remained low and inflammatory markers stayed high on day three. The survival rates of the groups were 85.7% in ST+IFN, 71.4% in ST+OSEL, 71.4% in ST+FAM, and 57.1% in ST groups on day seven. Conclusions: Antiviral drugs may be valuable in treating CPE to improve the clinical signs and survival. In addition, the decrease in NLR in favor of LYM may be an indicator of the early prognosis before the improvement of leukocytes, cytokines, and acute phase proteins in CPE.

Background: This present study was conducted to evaluate the anti-inflammatory and immune regulatory effects of Aucklandia lappa Decne (AL). Methods and Results: We measured cytotoxicity, nitric oxide (NO) content, mRNA expression (iNOS, IL-1${\alpha}$, IL-$1{\beta}$, and TNF-${\alpha}$), protein expression (iNOS, COX-2, and $I{\kappa}B$) and phagocytic activity in RAW264.7 cells. Male BALB/c mice were fed 100 mg/kg AL (Aucklandia lappa Decneon 70% ethanol extract) and 250 mg/kg AL for 4 weeks; thereafter, we observed B/T or $CD4^+/CD8^+$ lymphocyte subpopulation change, and expression patterns of $CD4^+$ and $CD8^+$ lymphocytes by immunohistochemical staining in mouse splenocytes and/or thymocytes. To determine the experimental concentration of AL, cell viability was measured by MTT assay and tested at $12.5{\mu}g/m{\ell}$ or less. AL inhibited the levels of NO, lymphokine production (IL-$1{\beta}$, and TNF-${\alpha}$), and mRNA (iNOS, IL-1${\alpha}$, IL-$1{\beta}$, and TNF-${\alpha}$) and protein (iNOS, and COX-2) expression. Additionally, the levels of $I{\kappa}B$, phagocytic activity, and splenic and thymic T lymphocytes, especially $T_H$ and $T_C$ cells were significantly increased in AL administered mice. The immuno-reactive density of $CD4^+$ and $CD8^+$ lymphocytes was stronger in AL groups than in the normal group. AL stimulated NO, iNOS, and COX-2, and regulated IL-1${\alpha}$, IL-$1{\beta}$, TNF-${\alpha}$, and $I{\kappa}B$ in macrophages treated with LPS (lipopolysaccharide). In addition, AL increased the phagocytic activity of macrophages and the immunity of mouse T ($T_H$, and $T_C$) cells. Conclusions: These results suggested that AL might show anti-inflammatory activity via the suppression of various inflammatory markers and immuno-regulatory activity.
