  • It is well known that the inflammation of somatic tissues, bladder and colon can alter the sensitivity of primary afferents innervating these tissues. To see if uterine afferents also show altered sensitivity, we examined their responses to the algesic agent bradykinin before and after induction of uterine inflammation. Inflammation was induced by injecting the mustard oil into the uterine lumen of adult female rats. After induction of inflammation, the response latency to bradykinin did not change, but the duration and peak of the response and integrated impulse discharges during the response period increased significantly. Furthermore, after inflammation, the level of resting discharges of the afferents was much higher. These results are consistent with the idea that the inflammation can sensitize the uterine afferents.

  • This experiment is carried out for test whether the addition temperament drugs of Danchisoyo-san have an anti-inflammatory effect and have suppression effect on immunocyte in the state of inflammation which induced by carageenan and zymosan. The freezing lyophilization powder which were extracted from Danchisoyo-san divided low dose group(200mg/kg-DSL) and high dose group(500mg/kg-DSH) and after melting in water, it was orally administered to the mouse. Compared with inflammation induced group which were induced by triggering-inflammation reagent carageenan and zymosan and normal contrast group, we measured the edema decrement effect, macrophage and spleen cell activation. 1. Danchisoyo-san has suppress inflammatory reaction induced by carrageenan. 2. Danchisoyo-san has suppress increasing activation of abdominal cavity macrophage cell in the carrageenan induced inflammation. 3. Danchisoyo-san has suppress increasing activation of spleen cell in the carrageenan induced inflammation. 4. Danchisoyo-san has suppress increasing activation of abdominal cavity macrophage in the zymosan induced inflammation. 5. Danchisoyo-san has suppress increasing activation of spleen cell in the zymosan induced inflammation. Based on the above result, Danchisoyo-san was improved its suppression effect to the inflammatory reaction through the suppression of spleen cell and macrophage activation. So we concluded that Danchisoyo-san is prospected as a anti-inflammatory agent to cure inflammation.

  • Atherosclerosis is a pathologic process occurring within the artery, in which many cell types, including T cell, macrophages, endothelial cells, and smooth muscle cells, interact, and cause chronic inflammation, in response to various inner- or outer-cellular stimuli. Atherosclerosis is characterized by a complex interaction of inflammation, lipid deposition, vascular smooth muscle cell proliferation, endothelial dysfunction, and extracellular matrix remodeling, which will result in the formation of an intimal plaque. Although the regulation and function of vascular smooth muscle cells are important in the progression of atherosclerosis, the roles of smooth muscle cells in regulating vascular inflammation are rarely focused upon, compared to those of endothelial cells or inflammatory cells. Therefore, in this review, we will discuss here how smooth muscle cells contribute or regulate the inflammatory reaction in the progression of atherosclerosis, especially in the context of the activation of various membrane receptors, and how they may regulate vascular inflammation.

  • Flavonoids are major plant constituents with numerous biological/pharmacological actions both in vitro and in vivo. Of these actions, their anti-inflammatory action is prominent. They can regulate transcription of many proinflammatory genes such as cyclooxygenase-2/inducible nitric oxide synthase and many cytokines/chemokines. Recent studies have demonstrated that certain flavonoid derivatives can affect pathways of inflammasome activation and autophagy. Certain flavonoids can also accelerate the resolution phase of inflammation, leading to avoiding chronic inflammatory stimuli. All these pharmacological actions with newly emerging activities render flavonoids to be potential therapeutics for chronic inflammatory disorders including arthritic inflammation, meta-inflammation, and inflammaging. Recent findings of flavonoids are summarized and future perspectives are presented in this review.

  • The present study was performed to investigate modification in the electrophysiological characteristics of cat dorsal horn cells during neurogenic inflammation induced by mustard oil. The results obtained were summarized as follows: 1) Following subcutaneous injection of mustard oil the majority of wide dynamic range (WDR) cells (10/15 units) showed enhanced responses (80%) to brush, while the responses to all types of mechanical stiumli were enhanced in 3/15 units. One cell was further activated by pinch and the another was not affected at all after induction of inflammation. 2) The sensitization of WDR cell was resulted from subcutaneous injection of mustard oil either inside or outside of the receptive field (RF), whereas the spontaneous activity increased only after mustard oil was injected inside of the RF. 3) In the animal with inflammation the responses of high threshold (HT) cell to noxious stimulus were not altered, while HT cell responded to such mechanical stimulus as pressure which was usually ineffective in normal animals. 4) After induction of inflammation, low threshold (LT) cell appeared to be converted to WDR cell, showing responses not only to brush but also to pressure and pinch. 5) The mustard oil-induced inflammation enhanced responses of WDR and HT cells to the thermal stimuli and also resulted in a pronounced after-discharge in WDR cells. 6) After subcutaneous injection of lidocaine, the increased background activity of WDR cells due to inflammation was almost completely abolished. 7) A subcutaneous injection of mustard oil inside of the RF invariably desensitized the dorsal horn cells which receive sensory inputs from the inflamed RF. From the results of Present study it was revealed that a neurogenic inflammation induced by mustard oil resulted in an enhancement of responses of cat dorsal horn cells to mechanical and thermal stimuli.

  • Leukotriene B4 (LTB4) is a lipid mediator of inflammation that is generated from arachidonic acid via the 5-lipoxygenase pathway. Previous studies have reported that the receptors of LTB4, BLT1, and BLT2 play mediatory roles in the allergic airway inflammation induced by ovalbumin (OVA). However, considering that house dust mites (HDMs) are the most prevalent allergen and well-known risk factor for asthmatic allergies, we are interested in elucidating the contributory roles of BLT1/2 in HDM-induced allergic airway inflammation. Our aim in this study was to investigate whether BLT1/2 play any roles in HDM-induced allergic airway inflammation. In this study, we observed that the levels of ligands for BLT1/2 [LTB4 and 12(S)-HETE (12(S)-hydroxyeicosatetraenoic acid)] were significantly increased in bronchoalveolar lavage fluid (BALF) after HDM challenge. Blockade of BLT1 or BLT2 as well as of 5-lipoxygenase (5-LO) or 12-lipoxygenase (12-LO) markedly suppressed the production of TH2 cytokines (IL-4, IL-5, and IL-13) and alleviated lung inflammation and mucus secretion in an HDM-induced eosinophilic airway-inflammation mouse model. Together, these results indicate that the 5-/12-LO-BLT1/2 cascade plays a role in HDM-induced airway inflammation by mediating the production of TH2 cytokines. Our findings suggest that BLT1/2 may be a potential therapeutic target for patients with HDM-induced allergic asthma.

  • Objectives : The aim of this study is to investigate the relationship between chronic low grade inflammation theory, psoriasis, and herbal medicine. Methods : We reviewed recent studies on the relationship between chronic low-grade inflammation, psoriasis, and herbal medicine through Pubmed. Results : The pathological basis for psoriasis is the action of inflammatory mediators by the activation of the immune response, which can be a cause of various cardiovascular, metabolic and psychological symptoms of psoriasis patients, in addition to skin lesions. The herbal medicines improve these inflammatory conditions and improve local lesions through herbal medicine such as Qingdai, which have a strong inhibitory effect on IL-17,22 production. Conclusions : Herbal medicines used in psoriasis are thought to be effective not only for the improvement of local psoriasis lesions through anti-inflammatory effect but also for the improvement of systemic inflammation associated with chronic low grade inflammation.

  • Inflammation is the crucial biological process of immune system which acts as body's defense and protective response against the injuries or infection. However, the systemic inflammation devotes the adverse effects such as multiple inflammation associated diseases. One of the best ways to treat this entity is by blocking the tumor necrosis factor alpha ($TNF-{\alpha}$) and TNF-related apoptosis-inducing ligand (TRAIL) to avoid the proinflammation cytokines production. Thus, this study aims to evaluate the potency of Sambucus bioactive compounds as anti-inflammation through in silico approach. In order to assess that, molecular docking was performed to evaluate the interaction properties between the $TNF-{\alpha}$ or TRAIL with the ligands. The 2D structure of ligands were retrieved online via PubChem and the 3D protein modeling was done by using SWISS Model. The prediction results of the study showed that caffeic acid (-6.4 kcal/mol) and homovanillic acid (-6.6 kcal/mol) have the greatest binding affinity against the $TNF-{\alpha}$ and TRAIL respectively. This evidence suggests that caffeic acid and homovanillic acid may potent as anti-inflammatory agent against the inflammation associated diseases. Finally, this study needs further examination and evaluation to validate the potency of Sambucus bioactive compounds.
