  • Due to the increasing prevalence and number of life-threatening cases, food allergy has emerged as a major health concern. The classic immune response seen during food allergy is allergen-specific IgE sensitization and hypersensitivity reactions to foods occur in the effector phase with often severe and deleterious outcomes. Recent research has advanced understanding of the immunological mechanisms occurring during the effector phase of allergic reactions to ingested food. Therefore, this review will not only cover the mucosal immune system of the gastrointestinal tract and the immunological mechanisms underlying IgE-mediated food allergy, but will also introduce cells recently identified to have a role in the hypersensitivity reaction to food allergens. These include IL-9 producing mucosal mast cells (MMC9s) and type 2 innate lymphoid cells (ILC2s). The involvement of these cell types in potentiating the type 2 immune response and developing the anaphylactic response to food allergens will be discussed. In addition, it has become apparent that there is a collaboration between these cells that contributes to an individual's susceptibility to IgE-mediated food allergy.

  • Hydatid disease is a zoonotic infection in humans. The disease is endemic in some parts of the world, including Africa, Australia, and Asia, where cattle grazing is common; the disease is spread by an enteric route following the consumption of food contaminated with the eggs of the parasite. Failure to identify this parasite results in delayed diagnosis and increased morbidity to the patient. Upon diagnosis, every possible step should be taken, both surgical and medical, to prevent anaphylactic reactions from the cystic fluid. Postsurgical long-term follow up along with periodical ultrasonography of the liver and computed tomography scan of the abdomen is essential to rule out possible recurrence.

  • The effects of extracts from various Oriental medicinal herbs on mast-cell-mediated allergic reactions were investigated in this study. Out of these extracts, the medicinal herb Atractylodis rhizoma alba exhibited the most potent activity in the cells, with $IC_50$ values of $20.5\;{\mu}g/ml$, by DNP-BSA and $33.04\;{\mu}g/ml$, by compound 48/80. Similar to the in vitro activity, Atractylodis rhizoma alba inhibited compound-48/80-induced systemic anaphylaxis by 31.3% at 300 mg/kg in mice. It also suppressed the secretion of $TNF-{\alpha}$, a major pro-inflammatory cytokine in the cells. These results may suggest that Atractylodis rhizoma alba shows anti-allergic activity in compound 48/80-induced anaphylactic mice through the inhibition of mast cells.

  • We studied the effects of the powders of Spirulina platensis (SPP) on anaphylactic reactions. SPP inhibited systemic anaphylaxis induced by compound 48/80 in rats. SPP also inhibited local anaphylaxis activated by anti-dinitrophenyl(DNP) IgE. Moreover, SPP dose-dependently inhibited histamine release in rat peritoneal mast cells activated by compound 48/80 or anti DNP-IgE. These results suggest that SPP may contain compounds with actions that inhibit mast cell degranulation in the rat.

  • Mast cells play an important role in the pathophysiologlcal changes observed in acute cutaneous and inflammatory diseases In order to see whether Kum-Hwang-San has an influence on mast cell- mediated immediate cutaneous reactions, the author has undertaken an animal study. Ears of mice were treated with a compound 48/80 solution topically at 30 min after the cutaneous application of Kum-Hwang-San. At each point, an ear swelling response was measured with a digimatic thickness micrometer. Ear swelling response induced by compound 48/80 was significantly suppressed dose-dependently by Kum-Hwang-San 30 min before topical application as compared with that in nonapplicated control mice, and the value returned to normal levels by 120 min. Compound 48/80- induced mast cell degranulation by Kum-Hwang-San was also remarkably decreased in accordance with the suppression in ear swelling response. Kum-Hwang-San dose-dependently inhibited histamine release from the rat peritoneal mast cells activated by compound 48/80. Another way to test acute cutaneous reaction is to induce passive cutaneous anaphylactic reaction. Kum-Hwang-San significantly inhibited passive cutaneous anaphylactic reaction activated by anti-dinitrophenyl IgE on both topical application and intradermal injection. Kum-Hwang-San also inhibited histamine release from the rat peritoneal mast cells induced by anti-DNP IgE. This study provides evidence that Kum-Hwang-San will be beneficial in the treatment of acute cutaneous diseases.

  • Shini-San has been used for treatment of allergic disease in Korea. However, its effect in experimental models remains unknown. The mast cell plays a pivotal role in initiating al1ergic response by secreting intracytoplasmic granular mediators such as histamine. The present report describes an inhibitory effect of Shini-San on mast cell-mediated immediate-type al1ergic reactions. Topical application of compound 48/80 can induce an ear swelling response in normal ($WBB6F_1-+/+$) mice but not in congenic mast cell-deficient $WBB6F_1-W/W^v$ mice. Shini-San inhibited concentration dependent mast cell-dependent ear swelling response induced by compound 48/80 in normal mice. Shini-San inhibited concentration-dependent passive cutaneous anaphylaxis induced by anti-dinitrophenyl (DNP) immunoglobulin E (IgE) in rats by topical application. Shini-San also inhibited in concentration-dependent fashion the histamine release from the rat peritoneal mast cells by compound 48/80 or anti-DNP IgE. Moreover, Shini-San had a significant inhibitory effect on compound 48/80-induced systemic anaphylactic reaction. These results indicate that Shini-San inhibits immediate-type allergic reactions by inhibition of mast cell degranulation in vivo and in vitro.

  • Gamisaenghyeolyunbueum (GSYE) is a traditional Oriental herbal medicine prescription, which has been used for the treatment of various allergic disorders, atopic dermatitis, extravasated bleeding from skin, especially skin related disease. The author investigated the effects of GSYE on mast cell-mediated allergic inflammatory reactions. GSYE dose-dependently (0.01-1 g/kg) inhibited compound 48180-induced systemic anaphylactic shock and ear swelling response. The inhibitory effect of GSYE on the histamine release from rat peritoneal mast cells induced by compound 48f80 reveals significantly (p<0.05) at concentrations ranging from 0.01 to 1 mg/ml in a dose-dependent manner. GSYE also inhibited the passive cutaneous anaphylaxis(PCA) by oral administration at 1 g/kg. In addition, GSYE dose-dependently (0.01-1 g/kg) inhibited the phorbol 12-myristate 13-acetate(PMA) and A23187-induced tumor necrosis $factor-{\alpha}$ secretion from human mast cell line HMC-1 cells. These results indicate that GSYE may be a beneficial applicability in the allergic-related diseases.

  • Kounis syndrome is defined as the occurrence of acute coronary syndrome associated with vasoactive mediators, such as histamines in the setting of hypersensitivity and allergic reactions or anaphylactic insults. The condition can be caused by various drugs, foods, or environmental factors that cause allergic reactions. A 35-year-old male visited the emergency room with anaphylaxis accompanied by chest pain approximately 20 minutes after taking zaltoprofen, a nonsteroidal anti-inflammatory drug. After acute treatment for the anaphylaxis, the patient was stabilized and all symptoms disappeared, but the ischemic changes in the electrocardiogram and elevation of the cardiac enzymes were observed. The emergency cardiac angiography and echocardiography were all normal. The allergic reaction of this patient to zaltoprofen was believed to cause a temporary coronary arterial vasospasm, inducing Type 1 Kounis syndrome. Thus far, there have been case reports of Kounis syndrome caused by a range of nonsteroidal anti-inflammatory drugs, but there are no reports of the condition being caused by zaltoprofen. According to the pathophysiology, both cardiac and allergic symptoms must be solved simultaneously, so rapid treatment and diagnosis are needed. Doctors treating acute allergic reactions and anaphylaxis patients must check the cardiovascular symptoms thoroughly and consider the possibility of Kounis syndrome.

  • Objective : To investigate the effect between Fructus Immaturus Ponciri (FIP, the immature fruit of Poncirus trifoliata) and Fructus Ponciri (FP, the ripe fruit of Poncirus trifoliata) on mast cell-mediated immediate-type allergic reactions. Methods : We performed anaphylactic reaction, histamine release, cAMP, $TNF-{\alpha}$, IgE. Results : The aqueous extract of FIP dose-dependently inhibited systemic and local allergic reaction was induced by compound 48/80 or anti-dinitrophenyl (DNP) IgE in a murine model. FIP also significantly inhibited mast cell-dependent ear swelling response induced by topical application of compound 48/80. When mice were orally pretreated with FIP, the plasma histamine levels were reduced in a dose-dependent manner. FIP dose-dependently inhibited histamine release from the rat peritoneal mast cells (RPMCs) was activated by compound 48/80 or anti-DNP IgE. The level of cAMP in RPMCs, when FIP was added, increased compared with that of a normal or control. In addition, FIP had a significant inhibitory effect on anti-DNP IgE-induced tumor necrosis factor-a ($TNF-{\alpha}$) production from the RPMCs and IgE produced by lipopolysaccharide-stimulated murine whole spleen cells or U266B1 as human IgE-bearing B cells. However, FP showed the lower inhibition rate than those of FIP in above all allergic reactions. Conclusion : These data have important implications for our understanding of the clinical effects of FIP and FP on allergic diseases, and FIP is more effective than FP on the allergic reaction.

  • Perilla frutescens var. acuta Kudo (PF) is a traditional Korean medicinal herb for allergic reaction regulation. In the present study, we investigated the effect of 30% ethanol extract powder of PF (EPPF) and rosmarinic acid (RA), the active compound of EPPF on various allergic reactions using in vivo and in vitro models. EPPF and RA significantly inhibited compound 48/48-induced systemic anaphylactic reaction and histamine release (P < 0.05). In addition, EPPF and RA significantly inhibited passive cutaneous anaphylaxis (PCA) in a dose-dependent manner (P < 0.05). These effects were stronger than those of disodium cromoglycate, the reference drug tested. EPPF and RA also significantly inhibited production of inflammatory cytokines, tumor necrosis factor-a interleukin (IL)-6, and vascular endothelial growth factor on the PCA reaction and phorbol 12-myristate 13-acetate and calcium ionophore A23187-stimulated human mast cell line, HMC-1 cells (P < 0.05). Moreover, EPPF and RA showed an inhibitory effect on lipopolysaccharide (LPS)-induced IL-4 production from whole spleen cells. Finally, EPPF and RA significantly decreased IL-4-dependent IgE production by LPS-stimulated whole spleen cells (P < 0.05). In conclusion, these results indicate that EPPF has potent anti-allergic activities.
