  • Some clinical diseases, such as granulomatous thyroiditis, tuberculosis, and sarcoidosis can cause granulomatous inflammation in thyroid, and theses have various clinical presentations. Granulomatous thyroiditis is an inflammation of thyroid gland, and may be painful and tender in case of infection, radiation, or trauma. Otherwise, autoimmune conditions, medications, or an idiopathic fibrosis may cause to be a painless thyroididtis. It is self-limited, possibly viral, inflammatory thyroid disorder usually presented with thyroid pain and systemic symptoms. Tuberculosis of the thyroid occurs only rarely and the patient may be asymptomatic. In thyroid sarcoidosis, most common findings are painless, progressive enlargement of the thyroid with normal function. We have experienced a case of chronic granulomatous inflammation of thyroid gland presenting as a painless thyroid nodule and report it with a review of literature.

  • Adenophorae Radix (AR) has been used as a traditional medicine for various diseases. However, the regulatory mechanisms of AR in allergic inflammation are not yet understood. The present study was conducted to investigate the effect and mechanisms of AR on the mast cell-mediated allergic response. To determine the pharmacological mechanisms of AR in allergic inflammation, we evaluated the effects of AR on the production of tumor necrosis factor (TNF)-α, interleukin (IL)-6, IL-1β and IL-8 as well as the activation of nuclear factor-κB (NF-κB) and caspase-1 in phorbol 12-myristate 13-acetate plus calcium ionophore A23187 (PMACI)-stimulated human mast cells (HMC-1). Our results demonstrated that AR effectively attenuated the PMACI-induced production of TNF-α, IL-6, IL-1β and IL-8 in stimulated HMC-1. Additionally, we showed that the inhibitory effect of AR on inflammatory cytokines in PMACI-stimulated HMC-1 cells involved the suppression of the activation NF-kB/caspase-1 in PMACI-stimulated HMC-1. Collectively, these findings provide experimental evidence that AR may be a useful candidate for the treatment of allergic inflammation.

  • Water and chloroform/methanol extracts of the three local Malaysian snakehead fish, Channa striatus (striped snakehead), Channa micropeltes (giant snakehead) and Channa lucius (blotched snakehead) were evaluated for inhibitory activity in chronic inflammation, using cotton pellet granuloma test. Both water extracts of C. striatus and C. micropeltes showed marked inhibition of the transudative and proliferative components of chronic inflammation (42.9 and 31.2% respectively for C. striatus, 35.6 and 26.2% for C. micropeltes) when compared to those of mefenamic acid (25.1 and 21.3% respectively) and piroxicam (36.1 and 26.2% respectively). The chloroform/methanol extracts did not exhibit any anti-inflammatory effects. These results indicated that C. striatus has more anti-transudative and anti-proliferative activities than the extract of C. micropletes. C. lucius extract in contrast, did not inhibit these two components. This present study indicated the beneficial effects of the water extracts of C. striatus and C. micropeltes, but not C. lucius on chronic inflammation.

  • Inflammation is an immune response of the human body but excessive inflammation is taken as a major factor in the development of many diseases including autoimmune disorders, cancer and nerve disorders etc. In this regards the need is to suppress the inflammatory response. Suppression of extra or imperfect inflammatory response is not a big deal provided there is an exact knowledge of particular target in the body. Recent advancements in Pharmacological aspect made the therapy with improved outcomes in number of patients. Anticytokine therapy might be one of the important and novel approaches for inflammation and Arthritis. This can be achieved only when we go through the pathophysiology of expression and identification of mediators. Let's take an example of cytokine like interleukins (IL), chemokines, interferons (INF), tumor necrosis factors (TNF-α), growth factors, and colony stimulating factors) release pathway which is a major signalling protein in inflammatory response. In the present study we have reviewed the recent pharmacological therapeutic advancement, inflammatory mediators, receptors, and major signalling pathways. Such information will not only provide the idea about the mechanism of action of Pharmaceuticals and molecular targets but also it provides a new aspect for drug designing and new corrective approaches in existing clinical medicines. This study will be a source of good information for the researchers working in the area of drug designing and molecular Pharmacology especially in anti-inflammatory and anti arthritic medicines for target based therapy.

  • Matrix metalloproteinase (MMP)-9 plays an important role in the pathogenesis of bronchial asthma. Neovastat, having significant antitumor and antimetastatic properties, is classified as a naturally occurring multifunctional antiangiogenic agent. We evaluated the therapeutic effect of Neovastat on airway inflammation in a mouse model of asthma. BALB/c mice were immunized subcutaneously with ovalbumin (OVA) on days 0, 7, 14, and 21 and challenged with inhaled OVA on days 26, 29, and 31. Neovastat was administrated by gavage (5 mg/kg body weight) three times with 12 h intervals, beginning 30 min before OVA inhalation. On day 32, mice were challenged with inhaled methacholine, and enhanced pause (Penh) was measured as an index of airway hyperresponsiveness. The severity of airway inflammation was determined by differential cell count of bronchoalveolar lavage (BAL) fluid. The MMP-9 concentration in BAL fluid samples was measured by ELISA, and MMP-9 activity was measured by zymography. The untreated asthma group showed an increased inflammatory cell count in BAL fluid and Penh value compared with the normal control group. Mice treated with Neovastat had significantly reduced Penh values and inflammatory cell counts in BAL fluid compared with untreated asthmatic mice. Furthermore, mice treated with Neovastat showed significantly reduced MMP-9 concentrations and activity in BAL fluid. These results demonstrate that Neovastat might have new therapeutic potential for airway asthmatic inflammation.

  • Inflammation is a disease that continues to afflict large numbers of people and may cause other diseases, for example, rheumatoid arthritis, colon cancer, etc. prostaglandins(PGs), one of arachidonic acid metabolites, are major chemical mediators in the process of inflammation. In traditional herbal medicine, many kinds of herbal drugs have been widely used for the treatment of inflammation. So, we analyzed many publications until 2001 which worked on inhibition of $PGE_2$ synthesis by cyclooxygenase-2 (COX-2) with herbs and herb oriented single compounds. And then we tried to make interpretations of herbal traditional prescriptions for inflammation. There are significant correlations between herbal medicine prescribed and inhibitions of COX-2 activity. From our efforts and further researches, we expect to develop new-inflammatory herbal drugs which have more efficacy and fewer side effects.

  • Purpose: The aim of this work was to investigate the beneficial effects of rhamnazin against inflammation, reactive oxygen species (ROS)/reactive nitrogen species (RNS), and anti-oxidative activity in murine macrophage RAW264.7 cells. Methods: To examine the beneficial properties of rhamnazin on inflammation, ROS/ RNS, and anti-oxidative activity in the murine macrophage RAW264.7 cell model, several key markers, including COX and 5-LO activities, $NO^{\cdot}$, $ONOO^-$, total reactive species formation, lipid peroxidation, $^{\cdot}O_2$ levels, and catalase activity were estimated. Results: Results show that rhamnazin was protective against LPS-induced cytotoxicity in macrophage cells. The underlying action of rhamnazin might be through modulation of ROS/RNS and anti-oxidative activity through regulation of total reactive species production, lipid peroxidation, catalase activity, and $^{\cdot}O_2$, $NO^{\cdot}$, and $ONOO^{\cdot}$ levels. In addition, rhamnazin down-regulated the activities of pro-inflammatory COX and 5-LO. Conclusion: The plausible action by which rhamnazin renders its protective effects in macrophage cells is likely due to its capability to regulate LPS-induced inflammation, ROS/ RNS, and anti-oxidative activity.

  • Objectives The purpose of this study is to confirm the effect of alleviating inflammation through creating skin fat barrier from Scutellaria baicalensis extract. Methods Four-week-old Balb/C mice were divided into four groups: control group (Ctrl), lipid barrier eliminated group (LBEG), dexamethasone (DM) treated group after lipid barrier elimination (DMTG), and Scutellaria baicalensis (SB) treated group after lipid barrier elimination (SBTG). Scutellaria baicalensis extract were administered for 5 days after removal of the fat barrier. Changes in skin condition, improvement of the fat barrier, and relief of inflammation were observed in each group. Results Compared to LBEG and DMTG, pathological skin damage and tissue changes were less in SBTG, and transepidermal water loss (TEWL) and pH were also significantly reduced. Filaggrin was also significantly increased in SBTG. KLK7, PAR-2, and TSLP in SBTG also showed significant reduction compared to the LBEG and DMTG. Conclusions Scutellaria baicalensis extract restores skin barrier and relieves inflammation through the creation of skin fat barrier. This means that the Scutellaria baicalensis extract can regulate Th2 differentiation through the creation of the epithelial fat barrier.

  • Many cancers arise from sites of chronic inflammation, which creates an inflammatory microenvironment surrounding the tumor. Inflammatory substances secreted by cells in the inflammatory environment can induce the proliferation and survival of cancer cells, thereby promoting cancer metastasis and angiogenesis. Therefore, it is important to identify the role of inflammatory factors in cancer progression. This review summarizes the signaling pathways and roles of C-reactive protein (CRP) in various cancer types, including breast, liver, renal, and pancreatic cancer, and the tumor microenvironment. Mounting evidence suggests the role of CRP in breast cancer, particularly in triple-negative breast cancer (TNBC), which is typically associated with a worse prognosis. Increased CRP in the inflammatory environment contributes to enhanced invasiveness and tumor formation in TNBC cells. CRP promotes endothelial cell formation and angiogenesis and contributes to the initiation and progression of atherosclerosis. In pancreatic and kidney cancers, CRP contributes to tumor progression. In liver cancer, CRP regulates inflammatory responses and lipid metabolism. CRP modulates the activity of various signaling molecules in macrophages and monocytes present in the tumor microenvironment, contributing to tumor development, the immune response, and inflammation. In the present review, we overviewed the role of CRP signaling pathways and the association between inflammation and cancer in various types of cancer. Identifying the interactions between CRP signaling pathways and other inflammatory mediators in cancer progression is crucial for understanding the complex relationship between inflammation and cancer.

  • 27-Hydroxycholesterol (27OHChol), a prominent cholesterol metabolite present in the bloodstream and peripheral tissues, is a kind of immune oxysterol that elicits immune response. Recent research indicates the involvement of 27OHChol in metabolic inflammation (meta-inflammation) characterized by chronic responses associated with metabolic irregularities. 27OHChol activates monocytic cells such that they secrete pro-inflammatory cytokines and chemokines, and increase the expression of cell surface molecules such as pattern-recognition receptors that play key roles in immune cell-cell communication and sensing metabolism-associated danger signals. Levels of 27OHChol increase when cholesterol metabolism is disrupted, and the resulting inflammatory responses can contribute to the development and complications of metabolic syndrome, including obesity, insulin resistance, and cardiovascular diseases. Since 27OHChol can induce chronic immune response by activating monocyte-macrophage lineage cells that play a crucial role in meta-inflammation, it is essential to understand the 27OHChol-induced inflammatory responses to unravel the roles and mechanisms of action of this cholesterol metabolite in chronic metabolic disorders.
