Hypereosinophilic syndrome (HES) is characterized by the presense of hypereosinophilia with evidence of target organ damage. We report a patient diagnosed with eosinophilic cystitis and HES. A 7 year old boy had hematuria, dysuria, and increased urinary frequency for 1 day. Laboratory examinations revealed hypereosinophilia (eosinophils, $2,058/{\mu}L$), hematuria, and proteinuria. Abdominal sonography revealed diffuse and severe wall thickening of the bladder. The patient was treated initially with antibiotics. However, his symptoms did not improve after 7 days. A computed tomography scan demonstrated severe wall thickening of the bladder and the hypereosinophilia persisted (eosinophils, $2,985/{\mu}L$). The patient complained of chest discomfort, dyspnea, epigastric pain, and vomiting on hospital day 10. Parasitic, allergic, malignancy, rheumatologic, and immune workups revealed no abnormal findings. Chest X-rays, electrocardiography, and a pulmonary function test were normal; however, the hypereosinophilia was aggravated (eosinophils, $3,934/{\mu}L$). Oral deflazacort was administered. A cystoscopic biopsy showed chronic inflammation with eosinophilic infiltration. The patient's respiratory, gastrointestinal, and urinary symptoms improved after 6 days of steroids, and he was discharged. The eosinophil count decreased dramatically ($182/{\mu}L$). The hypereosinophilia waxed and waned for 7 months, and the oral steroids were tapered and stopped. This case describes a patient diagnosed with eosinophilic cystitis and HES.

Eosinophil is an improtant leukocyte in the development of various inflammatory diseases. Monocyte chemoattractant protein-1 (MCP-1) acts as a key regulator on monocyte movement, and activation of T cells and NK cells. However, the role of MCP-1 in eosinophils remains to be solved. In the present study, we examined the effect of MCP-1 on eosinophil migration, using human eosinophilic EoL-1 cells as an in vitro model of eosinophils. The surface expression of CCR2 in EoL-1 cells was little detected but MCP-1 strongly induced EoL-1 cell migration in a dose-dependent manner. Increased chemotactic activity due to MCP-1 was blocked by pertussis toxin, a $G_i/G_o$ protein inhibitor and U73122, a phospholipase C (PLC) inhibitor. These results suggest that MCP-1 activates $G_i/G_o$ protein and PLC and this signal pathway is involved in eosinphil movement. This finding supports the elucidation of pathogenic mechanism of eosinophilic inflammation such as asthma and atopic dermatitis.

Recently a major goal in asthma therapy is to reduce or prevent the inflammatory response of airway. Eosinophilic accumulation in the tissue is a prominent feature of allergic diseases including asthma. Production of chemokines by bronchial epithelial cells may contribute to the allergic inflammation by recruiting eosinophils. In this study we evaluated the inhibitory effect of Gamichungsangbohatang (GMCSBHT), used traditionally in treating asthma, on secretion of chemokines for eosinophils in human A549 epithelial cells. Chemokines such as eotaxin, RANTES, IL-8 were inhibited in a dose-dependent manner, but IL-16 showed no inhibition by GMCSBHT. These findings indicate that GMCSBHT might be a therapeutic value in treating asthma by suppression of chemokines secretion associated with local accumulation of eosinophils.

Background/Aims Although functional abdominal pain disorders (FAPDs) are common in children, the accurate pathogenesis of FAPDs is not known yet. Micro-inflammation, particularly tissue eosinophilia of gastrointestinal (GI) tract, has been suggested as the pathophysiology observed in several GI disorders. We aimed to evaluate eosinophilic infiltration throughout the entire GI tract in children with FAPDs, compared to those with inflammatory bowel diseases (IBD) and to normal reference values. Methods We included 56 children with FAPDs, 52 children with Crohn's disease, and 23 children with ulcerative colitis. All subjects underwent esophagogastroduodenoscopic and colonoscopic examination with biopsies. Tissue eosinophil counts were assessed in 10 regions throughout the GI tract. Results Eosinophil counts of the gastric antrum, duodenum, terminal ileum, cecum, and ascending colon were significantly higher in children with FAPDs compared to normal reference values. Eosinophil counts of the stomach and the entire colon were observed to be significantly higher in children with IBD than in those with FAPDs. Even after selecting macroscopically uninvolved GI segments on endoscopy in children with IBD, eosinophil counts of the gastric body, cecum, descending colon, sigmoid colon, and the rectum were also significantly higher in children with IBD than those with FAPDs. Conclusions Significantly high eosinophil counts of the stomach and colon were observed in the order of IBD, followed by FAPDs, and normal controls, regardless of endoscopically detected macroscopic IBD lesions in children. This suggests some contribution of GI tract eosinophils in the intrinsic pathogenesis of FAPDs in children.

Blood eosinophil counts have emerged as a chronic obstructive pulmonary disease (COPD) biomarker that predict the effects of inhaled corticosteroids (ICS) in clinical practice. Post-hoc and prospective analysis of randomized control trials have shown that higher blood eosinophil counts at the start of the study predict a greater response to ICS. COPD patients with frequent exacerbations (2 or more moderate exacerbations/yr) or a history of hospitalization have a greater response to ICS. Ex-smokers also appear to have a greater ICS response. Blood eosinophil counts can be combined with clinical information such as exacerbation history and smoking status to enable a precision medicine approach to the use of ICS. Higher blood eosinophil counts are associated with increased eosinophilic lung inflammation, and other biological features that may contribute to the increased ICS response observed. Emerging data indicates that lower blood eosinophil counts are associated with an increased risk of bacterial infection, suggesting complex relationships between eosinophils, ICS response, and the airway microbiome.

Effects of mahwang(Ephedrae herba) aqua-acupuncture at sinsoo (B-23)and Jisil(B-52)on adrenal cortical insufficiency were investigated in dexamethasone treated rats. Concentration of serum cortisol was decreased in dexamethasone treated rats. However, these values showed a tendency to increase in mahwang(Ephedrae herba) aqua-acupuncture groups. Concentration of serum total protein was increased in dexamethasone treated rats. However, these values were decreased by the mahwang(Ephedrae herba) aqua-acupuncture. The portion of neutrophils was decreased and the portion of lymphocytes and eosinophils were increased in dexamethasone treated rats. However, in mahwang(Ephedrae herba) aqua-acupuncture groups, the portion of neutrophils showed a tendency to increase and the portion of lymphocytes and eosinophils showed a tendency to decrease. In dexamethasone treated rats, the weight of adrenal glands were decreased, however these values were increased in mahwang(Ephedrae herba) aqua-acupuncture groups.

Objectives : The present study was to investigate the effect of extract of Chelidonii herba (ECH) on the proliferation and activation of eosinophils which were prepared from lung cells of asthma-induced mouse by ovalbumin (OVA) treatment. Methods : C57BL/6 mouse was exposed to OVA three times a week for 6 weeks. The mouse lung tissues were dissected out, chopped and dossiciated with collagenase (1 ${\mu}g$/ml). Eosinophils were activated by rIL-3/rmIL-5 co-treatments. The lung cells were treated with ECH, incubated for 48 hr at $37^{\circ}C$, and analyzed by flow cytometery, ELISA, RT-PCR, and immuno-histochemical analysis. Results : In FACS analysis, number of granulocyte/lymphocyte, $CD3e^-$/$CCR3^+$, $CD3e^+$/$CD69^+$, $CD4^+$ and $CD23^+$/$B220^+$ in asthma-induced lung cells were significantly decreased by ECH treatment compared to the control group. And mRNA expression for IL-4, IL-5, IL-13, CCR3 and eotaxin in asthma-induced lung cells, which was induced by rIL-3 plus rmIL-5 treatments, was significantly decreased by ECH treatment. In ELISA analysis, production levels of IL-3, IL-5, IL-13 and histamine in asthma-induced lung cells, which were induced by rIL-3 plus rmIL-5 co-treatment, were significantly decreased by ECH treatment. ECH treatments significantly inhibited the proliferation of eosinohils prepared from asthma-induced mouse lung tissues compared to the non-ECH treated control cells. Immunohistochemical analysis revealed that ECH treatment significantly decreased the levels of eosipnphil activation compared to non-treated cells. Conclusions : The present data suggested that Chelidonium majus L. may have an effect on the inhibition of parameters associated with asthma responses in eosinpophils, and thus implicate the possibility for the clinical application of Chelidonium majus L.

Cortex mori (Morus alba L.), the root bark of mulberry tree, has been used as an antiphlogistic, diuretic, and expectorant in herbal medicine. The purpose of this study was to determine whether Cortex mori could inhibit the ovalbumin (OA) -induced late asthmatic reaction in guinea pigs. Guinea pigs were sensitized by two exposures to an aerosol of OA(1.0%) and then challenged with aerosolized antigen(2.0%), The animals were pretreated by three inhalations of the aerosoled Cortex mori either before antigen sensitization or cahllenge. Bronchoalveolar lavage fluid(BALF) and peripheral blood were collected at 17 hours after OA challenge. The cell populations in BALF and peripheral blood were examined to determine the changes of the relative proportions of eosinophils,neutrophils and mononuclear cells etc. Beta-glucuronidase activity in BALF was measured to evaluate the alveolar macrophage activation. OA-induced histamine release from guinea pig peritoneal fluid cells was measured by radioisotope enzymatic asssay. Results were as follows. The number of eosinophils, neutriphils and lymphocytes recovered in BALF were significantly increased in the 17h following aerosol challenge with OA. Among them, eosinophil and neutriphils were decreased remarkably in group that had been preinhalated with Cortex mori. The number of lymphocytes in BALF were not decreased in group pretreated with CM before sensitization but decreased in Group pretreated with CM before challenge. After OA challenge, the number of eosinophils in peripheral blood were markedly increased, but Cortex mori inhibited significantly the OA-induced eosinophilia. Beta-glucuronidase activity in the supernatants of BALF were significantly increased in the 17h following aerosol challenge with OA, however, pretreatment of Cortex mori had no influence on Beta-glucuronidase activity, suggesting that Cortex mori had no inhibitory effect on OA-induced alveolar macrophage activation. Cortex mori inhibited the OA-induced histamine release from guinea pig peritoneal fluid cells. From the above results, it is suggested that Cortex mori contains some substances with an activity to inhibit the the OA-induced late phase reaction of the bronchial asthma in guinea pigs.
