  • Pro-inflammatory cytokine and brain-derived neurotrophic factor (BDNF) are modulated in post-traumatic stress disorder (PTSD). This study investigated the effects of ibuprofen (IBU) on enhanced anxiety in a rat model of PTSD induced by a single prolonged stress (SPS) procedure. The effects of IBU on inflammation and BDNF modulation in the hippocampus and the mechanisms underlying for anxiolytic action of IBU were also investigated. Male Sprague-Dawley rats were given IBU (20 or 40 mg/kg, i.p., once daily) for 14 days. Daily IBU (40 mg/kg) administration significantly increased the number and duration of open arm visits in the elevated plus maze (EPM) test, reduced the anxiety index in the EPM test, and increased the time spent in the center of an open field after SPS. IBU administration significantly decreased the expression of pro-inflammatory mediators, such as tumor necrosis $factor-{\alpha}$, $interleukin-1{\beta}$, and BDNF, in the hippocampus, as assessed by reverse transcription-polymerase chain reaction analysis and immunohistochemistry. These findings suggest that IBU exerts a therapeutic effect on PTSD that might be at least partially mediated by alleviation of anxiety symptoms due to its anti-inflammatory activity and BDNF expression in the rat brain.

  • Background: Post-traumatic stress disorder (PTSD) is a psychiatric disease that develops following exposure to a traumatic event and is a stress-associated mental disorder characterized by an imbalance of neuroinflammation. Korean Red Ginseng (KRG) is the herbal supplement that is known to be involved in a variety of pharmacological activities. We aimed to investigate the effects of KRG on neuroinflammation as a potential mechanism involved in single prolonged stress (SPS) that negatively influences memory formation and consolidation and leads to cognitive and spatial impairment by regulating BDNF signaling, synaptic proteins, and the activation of NF-κB. Methods: We analyzed the cognitive and spatial memory, and inflammatory cytokine levels during the SPS procedure. SPS model rats were injected intraperitoneally with 20, 50, or 100 mg/kg/day KRG for 14 days. Results: KRG administration significantly attenuated the cognitive and spatial memory deficits, as well as the inflammatory reaction in the hippocampus associated with activation of NF-κB in the hippocampus induced by SPS. Moreover, the effects of KRG were equivalent to those exerted by paroxetine. In addition, KRG improved the expression of BDNF mRNA and the synaptic protein PSD-95 in the hippocampus. Taken together, these findings demonstrate that KRG exerts memory-improving actions by regulating anti-inflammatory activities and the NF-κB and neurotrophic pathway. Conclusion: Our findings suggest that KRG is a potential functional ingredient for protecting against memory deficits in mental diseases, such as PTSD.

  • Asthma is characterized by a chronic inflammatory disorder of the airways that leads to tissue injury and subsequent structural changes collectively called airway remodelling. Characteristic changes of airway remodelling in asthma include goblet cell hyperplasia, deposition of collagens in the basement membrane, increased number and size of microvessels, hypertrophy and hyperplasia of airway smooth muscle, and hypertrophy of submucosal glands. Apart from inflammatory cells, such as eosinophils, activated T cells, mast cells and macrophages, structural tissue cells such as epithelial cells, fibroblasts and smooth muscle cells can also play an important effector role through the release of a variety of mediators, cytokines, chemokines, and growth factors. Through a variety of inflammatory mediators, epithelial and mesenchymal cells cause persistence of the inflammatory infiltrate and induce airway structural remodelling. The end result of chronic airway inflammation and remodelling is an increased thickness of the airway wall, leading to a increased the bronchial hyperresponsiveness and fixed declined lung function.

  • Purpose: Monogenic inflammatory bowel disease (IBD) patients do not respond to conventional therapy and are associated with a higher morbidity. We summarized the clinical characteristics of monogenic IBD patients and compared their clinical outcomes to that of non-monogenic IBD patients. Methods: We performed a retrospective cohort study of all children <18 years old who were diagnosed with IBD between 2005 and 2016. A total of 230 children were enrolled. Monogenic IBD was defined as a presentation age less than 6 years old with confirmation of a genetic disorder. We subdivided the groups into monogenic IBD (n=18), non-monogenic very early-onset IBD (defined as patients with a presentation age <6 years old without a confirmed genetic disorder, n=12), non-monogenic IBD (defined as all patients under 18 years old excluding monogenic IBD, n=212), and severe IBD (defined as patients treated with an anti-tumor necrosis factor excluding monogenic IBD, n=92). We compared demographic data, initial pediatric Crohn disease activity index/pediatric ulcerative colitis activity index (PCDAI/PUCAI) score, frequency of hospitalizations, surgical experiences, and height and weight under 3rd percentile among the patients enrolled. Results: The initial PCDAI/PUCAI score (p<0.05), incidence of surgery per year (p<0.05), and hospitalization per year (p<0.05) were higher in the monogenic IBD group than in the other IBD groups. Additionally, the proportion of children whose weight and height were less than the 3rd percentile (p<0.05 and p<0.05, respectively) was also higher in the monogenic IBD group. Conclusion: Monogenic IBD showed more severe clinical manifestations than the other groups.

  • Objectives : There have been many studies of the effect of Bee Venom therapy about arthritis, but no one study was reported about its whole functional mechanism to musculo-skeletal system. This study was designed to investigate the effect, Indication, and side effect of Bee Venom therapy on musculo-skeletal disease by literature review of articles. Results : The effects of Bee Venom therapy to musculo-skeletal system are divided to Anti_inflammatory effect and Anti-nociceptive effect. Anti_inflammatory effect is achieved through competitive chemotaxis, immuno-regulation, increasing of cortisol secretion by stimulating hypothalamus-pituitary gland-adrenal cortex axis. Anti-nociceptive effect is achieved by Anti-inflammatory mechanism and it works similar to anti-nociceptive effect of the acupuncture acting on central and peripheral nociceptive transduction system. The Bee Venom therapy could cause severe side effect, for example, hypersensitivity and anaphylaxis, injury to central nerve system and cardiovascular system, peripheral blood system, and renal dysfunction. Conclusions : With its Anti-inflammatory and Anti-nociceptive mechanism, Bee Venom therapy is considered that has good effects to autoimmune disease, chronic inflammation of various musculo-skeletal disease and various pain syndrome. But the clinician must be careful for its side effects.

  • Periodontitis is an inflammatory disorder of the periodontium, characterized by destruction of the tooth supporting tissues including alveolar bone and mediated by various pro-inflammatory mediators. Here, we demonstrated that HP08-0106, composed of four crude drugs-Gardenia jasminoides Grandiflora, Angelica gigas Nakai, Rehmannia glutinosa, and Schizonepeta tenuifolia in a weight ratio of 2:2:1:2, perturbs inflammatory responses, osteoclast formation in LPS-induced RAW 264.7 cells and alveolar bone resorption in ligature-induced periodontitis. HP08-0106 decreased the protein level of iNOS and COX2 as well as the secreted level of IL-$1{\beta}$, indicating that HP08-0106 has antiinflammatory effects. HP08-0106 also inhibited the expression of genes associated with osteoclastogenesis including c-Fos, MMP-9 and TRAP. Moreover, HP08-0106 exhibited a protective effect from alveolar bone loss in ligature-induced periodontitis animal models. Our results strongly suggest that HP08-0106 represent an important therapeutic tool to treat inflammatory disorders associated with bone loss such as periodontitis.

  • Ulcerative colitis (UC) is a typical inflammatory colon disorder. Platycodon grandiflorum (PG) is known to exert various beneficial effects including anti-oxidative and anti-bacterial properties and improvements in liver function. However, the improving effect and mechanism of PG on intestinal inflammation are not fully understood. The present research was designed to investigate the effect of PG on the clinical signs of DSS-induced colitis in mice. The ameliorative effects of PG on inflammatory cytokine expression and the activation of hypoxia-inducible-factor (HIF)-1α in DSS-treated colon tissue were also determined. Our results showed that mice treated with DSS displayed the main clinical symptoms of colitis, including weight loss, bloody stools, decrease in colon length and diarrhea and PG treatment significantly improved the clinical features induced by DSS in mice. PG inhibited the increase in the levels of inflammatory cytokines caused by DSS in colon tissues. We also showed that the anti-inflammatory mechanism of PG involved suppressing the activation of HIF-1α in DSS-treated colon tissues. Collectively, the findings of this study indicate the prospect of developing new drugs from PG for UC treatment.

  • Inflammatory bowel disease (IBD) is a chronic relapsing disorder of unknown etiology, which is believed to be multifactorial. Recently, the incidence of pediatric IBD has steeply increased in Korea since 2000. Poorly controlled disease activity can result in complications such as intestinal fistulae, abscess, and stricture, as well as growth retardation and delayed puberty in children. Because of a lack of confirmative tests, various diagnostic modalities must be used to diagnose IBD. Onset age, location, behavior, and activity are important in selecting treatments. Monogenic IBD must be excluded among infantile and refractory very-early-onset IBD. Early aggressive therapy using biologics has recently been proposed for peripubertal children to prevent growth failure and malnutrition.
