Sanyeoleumja (SY) is the traditional Korean medicinal prescription for the treatment of inflammatory diseases of eyes. In this study, the anti-inflammatory effects of SY water extract were investigated. To measure the anti-inflammatory effects of SY, we examined the productions of inflammatory factor including nitric oxide (NO), prostaglandin E2 (PGE₂), inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2), interleukin-6 (IL-6), interleukin-1β (IL-1β) in lipopolysaccharide (LPS)-induced RAW 264.7 cells. SY inhibited NO and PGE₂ production in a dose dependent manner and decreased the protein and mRNA expression of iNOS and COX-2. Also, SY decreased the mRNA expression of interleukin-6 (IL-6) and interleukin-1β (IL-1β). In conclusion, SY downregulated LPS-induced inflammatory factor productions, which could be a clinical basis for inflammatory diseases.

Lymphoid tissue inducer (LTi) cells have been characterized in mouse as a key cell when secondary lymphoid tissues are organized during development and memory T cells are formed after birth. In addition to their involvement in adaptive immune responses, recent studies show that they contribute to innate immune responses by producing large amount of interleukin (IL)-22 against microbial attack. Here, we compare IL-22-producing LTi and LTi-like cells in human and mouse and discuss their heterogeneity in different tissues.

We investigated the effect of Sungmagalkun-tang (SGT) on the allergy. We conformed compound 48/80-induced active systemic anaphylatic shock, anti-dinitrophenyl IgE-mediated passive cutaneous anaphylaxis and ovalbumin-induced anaphylatic shock. Also observed IL-4 and GM-CSF mRNA expression in ovalbumin-induced allergic lung tissue and RBL-2H3. Histamine release is measured in RBL-2H3. SGT inhibited active systemic anaphylatic shock, passive cutaneous anaphylaxis and ovalbumin-induced anaphylatic shock by oral administration. We observed that SGT was concentration-dependently reduced IL-4 and GM-CSF mRNA expression in ovalbumin-induced allergic lung tissue and RBL-2H3 by SGT. In addition, SGT reduced histamine release in RBL-2H3. These results indicate that SGT has anti-histamic effect and controls IL-4 and GM-CSF mRNA expression on allergy.

This study examines a clinical progress of treatment for the sequelae of facial palsy through Jung-ahn acupuncture. The patient in this case was diagnosed with facial paralysis a few years ago. The patient was treated with Korean medicine and Western medicine, but was given up without improvement. The paretic symptom was found out in left side of the face. Also facial spasm and epiphora caused by blepharoptosis were existed. The patient got 8 times Jung-ahn acupuncture treatment from September 18th, 2014 to September 26th, 2014. House-Brackmann facial nerve grading system(H-B scale) was implemented. On the first time of the treatment, H-B scale was Grade Ⅴ and facial nerve grading was 2/8. Facial spasm and epiphora caused by blepharoptosis in lower eyelid were appeared on facial expressions and conversation. After total 8 treatments(therapies), H-B scale was Grade Ⅲ and facial nerve grading was 5/8. The symptoms of facial paralysis and blepharoptosis were improved. Jung-ahn acupuncture is estimated to be effective in facial palsy sequela. More cases are required to develop treatment of facial palsy sequela.

The tumor microenvironment (TME) is formed by several immune cells. Notably, tumor-associated macrophages (TAMs) are existed in the TME that induce angiogenesis, metastasis, and proliferation of cancer cells. Recently, a point-mutated variant of IL-32θ was discovered in breast cancer tissues, which suppressed migration and proliferation through intracellular pathways. Although the relationship between cancer and IL-32 has been previously studied, the effects of IL-32θ on TAMs remain elusive. Recombinant human IL-32θ (rhIL-32θ) was generated using an Escherichia coli expression system. To induce M0 macrophage polarization, THP-1 cells were stimulated with PMA. After PMA treatment, the cells were cultured with IL-4 and IL-13, or rhIL-32θ. The mRNA level of M1 macrophage markers (IL-1β, TNFα, inducible nitric oxide synthase) were increased by rhIL-32θ in M0 macrophages. On the other hand, the M2 macrophage markers (CCL17, CCL22, TGFβ, CD206) were decreased by rhIL-32θ in M2 macrophages. rhIL-32θ induced nuclear translocation of the NF-κB via regulation of the MAPK (p38) pathway. In conclusion, point-mutated rhIL-32θ induced the polarization to M1-like macrophages through the MAPK (p38) and NF-κB (p65/p50) pathways.

Lysophosphatidic acid (LPA) is known to play a critical role in breast cancer metastasis to bone. In this study, we tried to investigate any role of LPA in the regulation of osteoclastogenic cytokines from breast cancer cells and the possibility of these secretory factors in affecting osteoclastogenesis. Effect of secreted cytokines on osteoclastogenesis was analyzed by treating conditioned media from LPA-stimulated breast cancer cells to differentiating osteoclasts. Result demonstrated that IL-8 and IL-11 expression were upregulated in LPA-treated MDA-MB-231 cells. IL-8 was induced in both MDA-MB-231 and MDA-MB-468, however, IL-11 was induced only in MDA-MB-231, suggesting differential LPARs participation in the expression of these cytokines. Expression of IL-8 but not IL-11 was suppressed by inhibitors of PI3K, NF-kB, ROCK and PKC pathways. In the case of PKC activation, it was observed that $PKC{\delta}$ and $PKC{\mu}$ might regulate LPA-induced expression of IL-11 and IL-8, respectively, by using specific PKC subtype inhibitors. Finally, conditioned Medium from LPA-stimulated breast cancer cells induced osteoclastogenesis. In conclusion, LPA induced the expression of osteolytic cytokines (IL-8 and IL-11) in breast cancer cells by involving different LPA receptors. Enhanced expression of IL-8 by LPA may be via ROCK, PKCu, PI3K, and NFkB signaling pathways, while enhanced expression of IL-11 might involve $PKC{\delta}$ signaling pathway. LPA has the ability to enhance breast cancer cells-mediated osteoclastogenesis by inducing the secretion of cytokines such as IL-8 and IL-11.

The purpose of this study is to report a clinical progress of sudden hearing loss through korean medicine. Between 26th Mar. 2014 and 19th Apr. 2014, she was treated with Chuna manual therapy every day and observed by Pure Tone Audiometry (before and after) and visual analogue pain scale (VAS). A patient was diagnosed with sudden hearing loss on 23th Dec. 2013 in Severance Hospital, she had sudden hearing loss on left side. She had 19 times treatments. At the first of treatment, her audibility was 20 dB on right side, 74 dB on left side and she had tinitus and ear fullness (VAS 8 / VAS 9). At the middle of treatment (2nd Apr. 2014), symptoms of tinitus and ear fullness started improving. State was tinitus VAS 6, ear fullness VAS 6. At the end of treatment (21th Apr. 2014), state was tinitus VAS 4, ear fullness VAS 4, and recorded 35 dB on right side, 80 dB on left side in pure tone audiometry. Chuna manual therapy is estimated to be good for sudden hearing loss especially on tinitus and ear fullness. More cases are required to develop treatment of sudden hearing loss.

Cholestatic liver is associated with hepatic inflammation and elevated proinflammatory cytokines. Recent studies indicate that certain cytokines can modulate bile secretion. In the present study, we have examined the role of interleukin (IL-2) on the bile secretion by a combination of study models. To examine the relevance of IL-2 on bile secretion, the expression of IL-2 and IL-2 receptor (IL-2R) of isolated normal and bile duct ligated (BDL) rats cholangiocytes was first measured by RT-PCR. In BDL rats, the expression of IL-2 and IL-2R was significantly increased compared with normal rats. To study the effect of IL-2 on bile secretion, bile flow was measured in normal and BDL rats. At the level of cholangiocytes, secretory responses of isolated bile duct unit (IBDU)s were quantified by videomicroscopy. The administrations of IL-2 had no significant effect on basal bile secretion in normal and BDL rats. There was no significant effect of IL-2 on basal bile ductular secretion as evidenced by no significant difference in luminal area of the IBDUs perfusedwith 100 pM of IL-2 from those of albumin carrier control. However, the secretin-stimulated bile ductular secretion was significantly (P < 0.01) inhibited by $34{\pm}4%$ (normal, n = 12), $21{\pm}5.3%$ (BDL 2 wk, n = 12) and $15{\pm}5.2%$ (BDL 4 wk, n = 12) with the co-administration of IL-2. As with other cytokines, physiologically relevant concentration of IL-2 can significantly inhibit secretin-stimulated bile ductular secretion. These findings support the important roles of cytokines in modulating bile secretion and may contribute to the cholestasis seen in cholestatic liver diseases.
