In this study, 34 Traditional Chinese Medicine (TCM) compounds were screened for potential anabolic and anti-inflammatory properties on human osteoarthritic (OA) chondrocytes. The anabolic effects were assessed by measuring the glycosaminoglycan (GAG) relative to the DNA content using a 3D pellet culture model. The most chondrogenic compounds were tested in an inflammatory model consisting of 3 days of treatment with cytokines (IL-1β/TNF-α) with or without supplementation of TCM compounds. The anti-inflammatory effects were assessed transcriptionally, biochemically and histologically. From the 34 compounds, Vanilic acid (VA), Epimedin A (Epi A) and C (Epi C), 2′′-O-rhamnosylicariside II (2-O-rhs II), Icariin, Psoralidin (PS), Protocatechuicaldehyde (PCA), 4-Hydroxybenzoic acid (4-HBA) and 5-Hydroxymethylfurfural (5-HMF) showed the most profound anabolic effects. After induction of inflammation, pro-inflammatory and catabolic genes were upregulated, and GAG/DNA was decreased. VA, Epi C, PS, PCA, 4-HBA and 5-HMF exhibited anti-catabolic and anti-inflammatory effects and prevented the up-regulation of pro-inflammatory markers including metalloproteinases and cyclooxygenase 2. After two weeks of treatment with TCM compounds, the GAG/DNA ratio was restored compared with the negative control group. Immunohistochemistry and Safranin-O staining confirmed superior amounts of cartilaginous matrix in treated pellets. In conclusion, VA, Epi C, PS, PCA, 4-HBA and 5-HMF showed promising anabolic and anti-inflammatory effects.

Trigona honey (TH) is well known for its therapeutic characteristics. To date, the study of Trigona honey as a prophylactic or immune booster prior to the bacterial infection of the invivo model is not well covered. This study aims to investigate anti-inflammatory and immune activities in Wistar rats infected with respiratory infection following with Trigona honey. 25 Wistar rats were assigned to possitive groups, negative control group, positive control group was fed TH (5 g / kg body weight) orally, the untreated group was infected with Staphylococcus aureus to induce respiratory infection, the treated group has been infected with S. aureus followed by treatment with TH at a dose of 1.5 ×108 CFU / mL and the preventive group ingested TH one week before S. aureus infection. Blood was obtained for biochemical analysis. Lung tissues have been collected for molecular examination. The results showed a significant decrease in serum levels of ALT, AST, urea and creatinine in the preventive and treated groups, serum IgG increased significantly (P<0.05) in the preventive and treated groups, IFN-y increased in the preventive group while decreased in the treated group, and IL-8 increased in the treated group while decreased in the preventive group. The mRNA expression of AGP is up-regulated in the positive control, preventive and treated groups. The α2-MG, TNF-α , and mRNA expressions showed lower regulation after administration of TH in preventive and treated groups. The results show the ability of TH to counteract immune and inflammatory changes in serum levels and gene expressions.

Abstract Background Rheumatoid arthritis (RA) is an autoimmune disease which causes disability and threatens the health of humans. Therefore, it is of great significance to seek novel effective drugs for RA. It has been reported that various ginsenoside monomers are able to treat RA. However, it is still unclear which ginsenoside is the most effective and has the potential to be developed into an anti-RA drug. Methods The ginsenosides, including Rg1, Rg3, Rg5, Rb1, Rh2 and CK, were evaluated and compared for their therapeutic effect on RA. In in vitro cell studies, methotrexate (MTX) and 0.05% dimethyl sulfoxide (DMSO) was set as a positive control group and a negative control group, respectively. LPS-induced RAW264.7 cells and TNF-α-induced HUVEC cells were cultured with MTX, DMSO and six ginsenosides, respectively. Cell proliferation was analyzed by MTT assay and cell apoptosis was carried out by flow cytometry. CIA mice model was developed to evaluate the therapeutic efficacy of ginsenosides. The analysis of histology, immunohistochemistry, flow cytometry and cytokine detections of the joint tissues were performed to elucidate the action mechanisms of ginsenosides. Results All six ginsenosides showed good therapeutic effect on acute arthritis compared with the negative control group, Ginsenoside CK provided the most effective treatment ability. It could significantly inhibit the proliferation and promote the apoptosis of RAW 264.7 and HUVEC cells, and substantially reduce the swelling, redness, functional impairment of joints and the pathological changes of CIA mice. Meanwhile, CK could increase CD8 + T cell to down-regulate the immune response, decrease the number of activated CD4 + T cell and proinflammatory M1-macrophages, thus resulting in the inhibition of the secretion of proinflammatory cytokine such as TNF-α and IL-6. Conclusion Ginsenoside CK was proved to be a most potential candidate among the tested ginsenosides for the treatment of RA, with a strong anti-inflammation and immune modulating capabilities.

Objective This study investigated the inhibitory effect of baicalin on orthodontically induced inflammatory root resorption in rats. Methods Forty-five male Wistar rats were randomly divided into three groups of 15 rats each. Fifty grams of force was used to establish an orthodontic tooth movement model. Baicalin (40 mg/kg) was locally injected into rats in the baicalin group at 3-day intervals; concurrently, normal saline was injected into rats in the negative control group. On the 21st day after orthodontic treatment, the tooth movement distance and root resorption area ratio were measured. Histomorphology changes were observed by hematoxylin and eosin staining and immunohistochemistry. Results There was no significant difference in tooth movement distance between groups. The root resorption area ratio was significantly lower in the baicalin group than in the negative control group. Runx-2 expression was significantly higher in the baicalin group than in the negative control group, while tumor necrosis factor (TNF)-α expression was significantly lower in the baicalin group than in the negative control group. Conclusions Baicalin inhibits orthodontically induced inflammatory root resorption by enhancing the expression of Runx-2 and reducing the expression of TNF-α, but does not affect tooth movement distance.

Abstract The study aimed to investigate the possible anti-inflammatory activity of larch sawdust as feed supplement in lactating sows’ diet and its possible effect on the prevalence of Postpartum Dysgalactia Syndrome under field conditions. In a Greek farrow-to-finish pig farm, fifteen sows were randomly and equally allocated to a negative control group (NC group), a positive control group (PC group), and a treatment group (LT group). The animals of the first two groups received 99% basic diet and 1% corn starch, while LT group animals received 99% basic diet and 1% larch sawdust. The whole trial period lasted 35 days (7 days prior to farrow – day of weaning). At parturition day, animals of the PC group received 2 ml of an anti-inflammatory drug intramuscularly (meloxicam, Metacam®, Boehringer Ingelheim Vetmedica), while the animals of both other groups, received 2 ml of normal saline. Results showed insignificant differences among experimental groups for parameters such as post-partum rectal temperature and piglets performance. On the contrary, a significant increase of mean milk lactation index was observed in LT and PC groups on the 4th day of lactation period, when compared with NC group (p=0.014). Additionally, mean IL-6 concentrations in blood in the LT group showed a tendency for reduction when compared with those found in NC, and insignificant difference (p>0.05) when compared with those observed in PC group 24 hours postpartum. Moreover, the respective TNFα mean level in the LT group at 24 and 72 hours after parturition was similar to that found in PC group, respectively) and significantly lower than that determined in the NC group (p=0.003, p=0.024. The results suggest a possible anti-inflammatory effect of larch sawdust in sows.

Imiquimod-induced psoriasis is an animal model of psoriasis.  The antidiabetic metformin had anti-inflammatory, immunomodulation, antiangiogenesis and antiproliferative effect. The objective of this study was to evaluate the possible beneficial effect of metformin gel against imiquimod-induced psoriasis-like form by scoring the erythema and scaling besides measuring of tissue homogenate levels of IL17/IL23. Swiss albino mice were used in this experiment imiquimod 5% cream applied on shaved back of mice for six days, and this is an induction group and compared with a negative control group that involved mice treated with ointment base only for six days. Third group; metformin 10% gel applied on the back of mice with imiquimod for six days. The fourth group included used of metformin 15% gel with imiquimod for six days. This data was analysed for significant level when p ≥ 0.05 by using either ANOVA test for biochemical parameters levels evaluation.    Furthermore, imiquimod 5% cream of induction group caused an elevation of inflammatory parameters; IL17 and IL23 in skin tissue homogenate when being compared to   IL17   and IL23 level of the control group. Whereas, metformin 10% gels showed levels of IL17 and IL23 with significant different from induction group. In addition, metformin 15% gels exerted a significantly low level of IL17 and IL23. The possible considerable antipsoriatic activity of topical metformin gel through reducing scaling and erythema and mediated through modest anti-inflammatory effects by suppressing levels of IL17/23.
