Objective: An experiment was conducted to evaluate the effects of Lonicera japonica extract (LJE) on milk production, rumen fermentation and blood biomarkers of energy metabolism, inflammation and oxidative stress during the perinatal period of Holstein dairy cows. Methods: Eighteen Holstein dairy cows were used in a complete randomized design experiment with 3 dietary treatments and 6 cows per treatment. All cows received the same basal total mixed ration (TMR) including a prepartal diet (1.35 Mcal of net energy for lactation [NEL]/kg of dry matter [DM], 13.23% crude protein [CP]) from -60 d to calving and a postpartal diet (1.61 Mcal of NEL/kg of DM, 17.39% CP) from calving to 30 days in milk (DIM). The 3 dietary treatments were TMR supplemented with LJE at 0 (control), 1 and 2 g/kg DM, respectively. LJE was offered from 21 d before calving to 30 DIM. Dry matter intake (DMI) and milk production were measured daily after calving. Milk and rumen fluid samples were collected on 29 and 30 d after calving. On -10, 4, 14, and 30 d relative to calving, blood samples were collected to analyze the biomarkers of energy metabolism, inflammation and oxidative stress. Results: Compared with control diet, LJE supplementation at 1 and 2 g/kg DM increased DMI, milk yield and reduced milk somatic cell count. LJE supplementation also decreased the concentrations of blood biomarkers of pro-inflammation (interleukin-1β [IL-1β], IL-6, and haptoglobin), energy metabolism (nonesterified fatty acid and β-hydroxybutyric acid) and oxidative stress (reactive oxygen metabolites), meanwhile increased the total antioxidant capacity and superoxide dismutase concentrations in blood. No differences were observed in rumen pH, volatile fatty acid, and ammonia-N (NH3-N) concentrations between LJE supplemented diets and the control diet. Conclusion: Supplementation with 1 and 2 g LJE/kg DM could increase DMI, improve lactation performance, and enhance anti-inflammatory and antioxidant capacities of dairy cows during perinatal period.
Background: PM is known to induce various pulmonary diseases, including asthma, cancer, fibrosis and chronic bronchitis. Despite the epidemiological evidence the pathogenesis of PM-related pulmonary diseases is unclear. Methods: This study examined the effects of PM exposure on the secretion of $TNF-{\alpha}$ and $IL-1{\beta}$ in the cultured alveolar macrophages. The cultured primary alveolar macrophages were treated with the medium, PM ($5{\sim}20{\mu}g/cm^2$), LPS (5ng/ml), and PM with LPS for 24h and 48h respectively. ELISA was used to assay the secreted $TNF-{\alpha}$ and $IL-{\beta}$ in the culture medium. Western blotting was used to identify and determine the level of proteins isolated from the culture cells. The cells cultured in the $Lab-Tek^{(R)}$ chamber slides were stained with immunocytochemical stains. Results: PM induced $TNF-{\alpha}$ and $IL-1{\beta}$ secretion in the culturing alveolar macrophages, collected from the SPF and inflammatory rats. However, the effects were only dose-dependent in the inflammatory macrophages. When the cells were co-treated with PM and LPS, there was a significant synergistic effect compared with the LPS in the both cell types. Conclusion: PM might be play an important role in the induction and/or potentiation of various lung diseases by oversecretion of $TNF-{\alpha}$ and $IL-1{\beta}$.
The enhanced differentiation and activation of osteoclasts (OCs) in the inflammatory arthritis such as rheumatoid arthritis (RA) and gout causes not only local bone erosion, but also systemic osteoporosis, leading to functional disabilities and morbidity. The induction and amplification of NFATc1, a master regulator of OC differentiation, is mainly regulated by receptor activator of NF-κB (RANK) ligand-RANK and calcium signaling which are amplified in the inflammatory milieu, as well as by inflammatory cytokines such as TNFα, IL-1β and IL-6. Moreover, the predominance of CD4+ T cell subsets, which varies depending on the condition of inflammatory diseases, can determine the fate of OC differentiation. Anti-citrullinated peptide antibodies which are critical in the pathogenesis of RA can bind to the citrullinated vimentin on the surface of OC precursors, and in turn promote OC differentiation and function via IL-8. In addition to adaptive immunity, the activation of innate immune system including the nucleotide oligomerization domain leucine rich repeat with a pyrin domain 3 inflammasome and TLRs can regulate OC maturation. The emerging perspectives about the diverse and close interactions between the immune cells and OCs in inflammatory milieu can have a significant impact on the future direction of drug development.
Objectives : $18{\beta}$-Glycyrrhetinic acid (18betaGA) is an metabolite of glycyrrhizin in Glycyrrhiza (licorice). The present study investigated anti-inflammatory and anti-apoptosis effect of 18betaGA on the brain tissue of lipopolysaccharide (LPS)-treated C57BL/6 mice. Methods : 18betaGA was administered orally with low (30 mg/kg) and high (100 mg/kg) doses for 3 days prior to LPS (3 mg/kg) injection. Pro-inflammatory cytokines mRNA including tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$), interleukin (IL)-$1{\beta}$, IL-6, and inflammatory enzyme cyclooxygenase-2 (COX-2) mRNA were measured in the cerebral cortex, hippocampus, and hypothalamus tissue using real-time polymerase chain reaction at 24 h after the LPS injection. Histological changes of Cornu ammonis area 1 (CA1) neurons, Bax, Bcl-2, and caspase-3 expression in the hippocampus was also evaluated by immunohistochemistry and Western blotting method. Results : 18betaGA significantly attenuated the up-regulation of TNF-${\alpha}$, IL-$1{\beta}$, IL-6 mRNA, and COX-2 mRNA expression in the brain tissues induced by the LPS injection. 18betaGA also significantly attenuated the reductions of the thickness of CA1 and the number of CA1 neurons. The up-regulation of Bax protein expression in the hippocampal tissue by the LPS injection was significantly attenuated, while the ratio of Bcl-2/Bax expression was increased by 18betaGA treatment. 18betaGA also significantly attenuated the up-regulation of Bax and caspase-3 expression in the CA1 of the hippocampus. Conclusion : This results indicate that 18betaGA has anti-inflammatory and anti-apoptosis effect under neuroinflammation induced by the LPS injection and suggest that 18betaGA may be a beneficial drug for various brain diseases accompanied with the brain tissue inflammation.
In the present study, the antioxidant and anti-inflammatory activities of ethanolic extracts from Lathyrus japonicus at concentrations of 50, 100, and 200 ㎍/mL were investigated in LPS-stimulated, RAW264.7 cells. Antioxidant properties were determined using 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radical scavenging assays and ferric reducing antioxidant power assay. In addition, the production of reactive oxygen species (ROS) was measured using the 2',7'-dichlorofluorescein diacetate (DCFH-DA) probe by flow cytometry. To examine the anti-inflammatory activity of the extracts of L. japonicus, their effects on the levels of nitric oxide (NO); production of cytokines such as interleukin (IL)-1β, IL-10, and tumor necrosis factor-α (TNF-α); and the activities of enzymes such as inducible NOS (iNOS) and cyclooxygenase-2 (COX-2) were assessed. The IC50 values of the DPPH and ABTS radical scavenging assays were 476.09 ± 1.50 and 34.91 ± 0.37 ㎍/mL, respectively. In addition, L. japonicus extracts not only inhibited ROS production, but also the production of NO, IL-1β, and IL-10, and the activity of iNOS in a dose-dependent manner. In summary, the ethanolic extracts of L. japonicus could be used as a functional food additive and an anti-inflammatory agent owing to their antioxidant and anti-inflammatory activities
Dung beetle (Catharsius molossus, CA) is a well-known group of insects thanks to their exploitation of animal feces, a behavioral trait with a global impact on earth′s ecosystems. This study was conducted to investigate the effect of CA extract on a high-fat diet in SD rats. Male rats were divided into 5 groups. Animals were fed on a high-fat diet for seven weeks before and dung beetle extract for a month during the administration. Weight gain was decreased in ethanol extract from CA group. Administration of CA extract reduced the organ weight of testis and kidney, and adipose tissue weight. Lipid oxidative stress was evaluated measuring malondialdehyde level in liver. There were no significant differences in groups. Protein oxidative stress was evaluated measuring protein carbonyl content in blood. The protein carbonyl in blood was significantly decreased in ethanol and acetone extracted dung beetle groups (p<0.05). Meanwhile, the protein carbonyl in hepatocyte was not significant among the groups. Fibronectin and laminin by using D-HUVEC cell in vitro were measured by ELISA assay. There was significance in CA extract. The level of IL-10, IL-1β, VEGF, eNOS was evaluated by ELISA. There was significance in IL-10 compared to control (p<0.05). SOD and GPx tended to increase by CA extract. Furthermore, CAT was increased significantly by CA extract (p<0.05). After administration of CA extracts the composition of saturated fatty acid in adipose tissue tend to decrease, while unsaturated fatty acid increases. In conclusion, dung beetle had anti-hyperglycemia effects of oxidative stress and antioxidant activity.

Coptis chinensis has been used in the treatment of various diseases such as soothing, anti-inflammation, antimicrobial and antipyretic in oriental traditional medicine. In this study, we investigated the effect of hot water extract of Coptis chinensis(CCW) on skin barrier and inflammation-related factors in UVB and TNF-α/IFN-γ-induced HaCaT cells and evaluated its potential as a moisturizing and anti-inflammatory material. Based on result, the amount of HA (Hyaluronic acid) production and protein and mRNA expression of filaggrin were measured. In TNF-α/IFN-γ-induced HaCaT cells, CCW increased the amount of HA production in a concentration-dependent manner. In the measurement of protein and mRNA expression of filaggrin, the expression rate increased as the concentration of CCW increased. In UVB-induced HaCaT cells, CCW decreased the production of ROS and showed significant results with EGCG ((-)-epigallocatechin-3-gallate), a positive control. In addition, CCW inhibited the expression of inflammatory cytokines TNF-α, IL-1β, IL-6, and IL-8 in TNF-α/IFN-γ-induced HaCaT cells. It was confirmed that the protein and mRNA expression of COX-2, a major factor in skin inflammation, was decreased in a concentration-dependent manner. These results suggest that hot water extract from Coptis chinensis can be used as a cosmetic material having a moisturizing and anti-inflammatory effect.
Objective : Anterior cervical spine surgery (ACSS) is a common surgical procedure used to treat cervical spinal degenerative diseases. One of the complications associated with ACSS is prevertebral soft tissue swelling (PSTS), which can result in airway obstruction, dysphagia, and other adverse outcomes. This study aims to investigate the correlation between various cervical sagittal parameters and PSTS following single-level ACSS, as well as to identify independent risk factors for PSTS. Methods : A retrospective study conducted at a single institution. The study population included all patients who underwent single-level ACSS between January 2014 and December 2022. Patients with a history of cervical spine surgery or trauma were excluded from the study. The presence and severity of PSTS was assessed by reviewing pre- and postoperative imaging studies. The potential risk factors for PSTS that were examined include patient age, sex, body mass index, tobacco use, comorbidities, serum albumin levels, operative time, implant type, implanted level, and various cervical spine sagittal parameters. Multivariate linear regression analysis was performed to identify the independent risk factors for PSTS. Results : A total of 62 consecutive patients who underwent single-level ACSS over a 8-year period at a single institution were enrolled in this study. Only preoperative segmental angle showed positive correlation with PSTS among various cervical spine sagittal parameters (r=0.36, p=0.005). Artificial disc replacement showed a negative correlation with PSTS (β=-0.38, p=0.002), whereas the use of demineralized bone matrix (DBM) had a positive impact on PSTS (β=0.33, p=0.009). We found that male sex, lower preoperative serum albumin, and implantation of upper cervical level (above C5) were independent predictors for PSTS after single-level ACSS (β=1.21; 95% confidence interval [CI], 0.27 to 2.15; p=0.012; β=-1.63; 95% CI, -2.91 to -0.34; p=0.014; β=1.44; 95% CI, 0.38 to 2.49; p=0.008, respectively). Conclusion : Our study identified male sex, lower preoperative serum albumin levels, and upper cervical level involvement as independent risk factors for PSTS after single-level ACSS. These findings can help clinicians monitor high-risk patients and take preventive measures to reduce complications. Further research with larger sample sizes and prospective designs is needed to validate these findings.

Objectives : The purpose of this study was to investigate the anti-inflammatory effect of Goihwa-san water extract(GHS) in vitro & in vivo. Methods : In vitro, we evaluated the anti-inflammatory effect of GHS by comparing the Raw 264.7 cells with 10, 30, 100, 300㎍/㎖ of GHS for 1 hour before Lipopolysaccharide(LPS) to the single LPS treated group. We examined the relative cell viability by MTT assay and the relative level of LPS, Loxoribine(LOX), Peptidoglycan(PGN), Flagellin(FLA)-induced NO production by using Griess reagent and measured relative iNOS protein level and COX-2 protein level by using western blot and Image analyzing system. We measured the production of TNF-α, IL-1β, and IL-6 by each ELISA kits and then measured the relative levels of IκBα, p-IκBα in whole-cell lysate fraction and NF-κB in nuclear fraction by using western blot and Image analyzing system. In vivo, we induced the paw edema by subcutaneous injection of 100㎕/rat CA and measured the swelling volume of paw by using a plethysmometer and then measured the relative iNOS protein level by using western blot. Results : As a result, in vitro, LPS, PGN-induced NO production was significantly inhibited by pretreatment with GHS. GHS reduced LPS, PGN-induced iNOS expression, PGN-induced COX-2 expression and LPS-induced production of cytokine(TNF-α, IL-1β, IL-6). Expression of IκBα was increased by pretreatment with GHS 100㎍/㎖. And the expression of p-IκBα and NF-κB were decreased by pretreatment with GHS 100㎍/㎖. In vivo, CA-induced inflammation rat model was used for the evaluation of the anti-inflammatory effect of GHS. 0.3 or 1.0g/kg of GHS significantly reduced the increases of paw swelling and iNOS expression in paw tissues. Conclusions : These results show that GHS can decrease inflammatory response via inhibition of the NF-κB pathway in vitro. And in vivo, the anti-inflammatory effect suggest the clinical basis of GHS for the treatment of inflammatory diseases.
