Objective: Chronic otitis media is an inflammation and infection of the middle ear which is persistent. Chronic otitis media occurs when the eustachian tube becomes blocked repeatedly, multiple infections, ear trauma, or swelling of the adenoids. A chronic ear may be the result of an acute ear infection that does not clear completely, or the result of recurrent ear infections. A chronic ear infection may be more destructive than an acute ear infection because its effects are prolonged, and it may cause permanent damage to the ear. Methods : Experimental animals made use of 4-5 weeks age(weight 20-25g) ICR(male)mouse. In the breeding farm, the lighting time was controlled from 7:00 am until 7:00 pm, the temperature was controlled within $22{\pm}0.5{\circ}$ and water and food were not limited. The extracts which were extracted from Hwangginaetak-san devided low dose group( 1.0g/kg-HN) and high dose group(3.0g/kg-HN), they were intragastrically administered to the mouse of sample A and sample B prior to LPS I.P injection. Compared with inflammation induced group which were induced by LPS, we measured the WBC count, IL-6 level in plasma and TNF-${\alpha}$ level in plasma. Results: 1. Hwangginaetak-san decreased WBC count in inflammatory reaction induced by LPS 2. Hwangginaetak-san decreased IL-6 level in inflammatory reaction induced by LPS. 3. Hwangginaetak-san didn't decreased TNF-${\alpha}$ level in inflammatory reaction induced by LPS Conclusion: According to above results, Hwangginaetak-san was improved its suppression effect to the inflammatory reaction through WBC count and IL-6 level. So Hwangginaetak-san is considered to be used for treatment of chronic otitis media by controlling the WBC count and IL-6 level in plasma.

Recent technical advances have enabled unbiased transcriptomic and epigenetic analysis of each cell, known as "single-cell analysis". Single-cell analysis has a variety of technical approaches to investigate the state of each cell, including mRNA levels (transcriptome), the immune repertoire (immune repertoire analysis), cell surface proteins (surface proteome analysis), chromatin accessibility (epigenome), and accordance with genome variants (eQTLs; expression quantitative trait loci). As an effective tool for investigating robust immune responses in coronavirus disease 2019 (COVID-19), many researchers performed single-cell analysis to capture the diverse, unbiased immune cell activation and differentiation. Despite challenges elucidating the complicated immune microenvironments of chronic inflammatory diseases using existing experimental methods, it is now possible to capture the simultaneous immune features of different cell types across inflamed tissues using various single-cell tools. In this review, we introduce patient-based and experimental mouse model research utilizing single-cell analyses in the field of chronic inflammatory diseases, as well as multi-organ atlas targeting immune cells.

The process of drug discovery and drug development consumes billions of dollars to bring a new drug to the market. Drug development is time consuming and sometimes, the failure rates are high. Thus, the pharmaceutical industry is looking for a better option for new drug discovery. Drug repositioning is a good alternative technology that has demonstrated many advantages over de novo drug development, the most important one being shorter drug development timelines. In the last two decades, drug repositioning has made tremendous impact on drug development technologies. In this review, we focus on the recent advances in drug repositioning technologies and discuss the repositioned drugs used for inflammatory diseases such as sepsis, asthma, and atopic dermatitis.

The effects of ethanolic extract (EEP) of propolis on chronic inflammation were evaluated using rat adjuvant arthritis. In the chronic inflammatory animal model, the arthritis index was suppressed by EEP treatments (50 mg/kg/day and 100 gm/kg/day, p.o.). Moreover, physical weakness, induced by the chronic disease state, was dose-dependently improved in the EEP-treated groups. It s analgesic effect, assessed using the tail-flick test, was comparable to prednisolone (2.5 mg/kg/day, p.o.) and acetyl salicylic acid (100 mg/kg/day, p.o.). In carrageenan rat hind paw edema, which was conducted to test the effects of subfractions of EEP, the petroleum ether sub-fraction (100 mg/kg, p.o.) showed an inhibitor effect on the paw edema whereas EEP (200 mg/kg, p.o.) showed a significant anti-inflammatory effect at 3 and 4 hrs after carrageenan injection. From these results, we conclude that the ethanolic extract of propolis had a profound anti-inflammatory effects on both chronic and acute inflammations.

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.

Chronic inflammatory demyelinating polyneuropathy (CIDP) is a chronic recurrent acquired immune-mediated disease of the peripheral nerves that presents with progressive sensory and motor deficits in all four limbs. Cranial nerve involvement is not as common as in Guillain-Barre syndrome, and central nervous system involvement including optic neuritis has rarely been reported in patients with CIDP. We recently experienced a case with classic CIDP involving bilateral facial and trigeminal nerves, right lower cranial nerves, and the right optic nerve.

Purpose: Chronic inflammatory gingival lesions occur as pyogenic granulomas or non-specific chronic suppurative lesions. Methods: Of the 59 chronic inflammatory gingival lesions examined, plasma cell granuloma (n=14), which showed an intense antibody-mediated immune reaction with the increased infiltration of plasma cells, was observed as a pseudotumor-like gingival overgrowth and myofibroblastic or fibrohistiocytitc proliferation of stromal cells with a heavy collection of plasma cells. The levels of CD3, CD20, CD31, CD68, RANKL, cathepsin G, cathepsin K, lysozyme, TNF${\alpha}$, MMP-2, and MMP-9 in the 14 cases of gingival plasma cell granuloma with immunohistochemical detection were measured to determine the pathogenetic progresses of the plasma cell granuloma compared to the common pyogenic granuloma (n=45) in the gingiva. Results: The gingival lesions of the plasma cell granuloma could be divided into three histological types, plasma cell predominant type (PPT, n=8), mixed inflammatory cell type (MICT, n=2), and sclerosed fibrosis type (SFT, n=4). The PPT showed a condensed infiltration of plasma cells into the perivascular spaces of the granulomatous lesion with frequent formation of Russel's body in their cytoplasm. The MICT showed the concomitant infiltration of many macrophages together with plasma cells, resulting in the diffuse destruction of stromal fibrous tissue. The SFT showed granulomatous lesions replaced gradually by thick collagenous fibrous tissue, resembling an inflammatory pseudotumor. The SFT expressed strongly the lymphocytic markers, CD3 and CD20, and the macrophage/monocyte markers, CD31 and CD68, but showed reduced expression of common inflammatory markers, TNF${\alpha}$, cathepsin G, lysozyme, MMP-2, and MMP-9, as well as the reduced expression of osteoclastogenic markers, RANKL and cathepsin K. Conclusion: These results suggest that a gingival plasma cell granuloma shows variable gene expression for cell-mediated immunity and stromal tissue degeneration, undergoing sclerotic fibrosis with a persistent inflammatory reaction.

Pharmacological investigations were carried out with aqueous methanolic extract (AME) of Swietenia mahagoni (L.) Jacq. (Meliaceae) leaves. Acute toxicity studies revealed that the $LD_{50}$ dose of AME was 600 mg/kg, i.p. AME was found to possess significant anti-inflammatory activity in acute, sub-chronic and chronic models of inflammation. AME selectively inhibited cyclooxygenase (COX)-2 activity, which is involved in arachidonic acid metabolism and biosynthesis of prostaglandins under inflammatory conditions. Treatment with AME significantly enhanced total peritoneal cell count and the number of macrophages in normal mice, which revealed that AME may also alter the immune response along with its anti-inflammatory effect. The saponins or the alkaloids present in AME may be responsible for the anti-inflammatory activity.
