  • We compared the effect between CAS and WAS(root, stem) on mast cell-mediated allergic reaction. CAS, WAS-root and WAS-stem, significantly inhibited compound 48/80-induced systemic allergic reaction(1g/kg) and histamine release from RPMC(1mg/ml). CAS, WAS-root and WAS-stem also inhibited passive cutaneous anaphylactic reaction. In addition, IgE-induced $TNF-{\alpha}$ secretion from RBL-2H3 was inhibited by pretreatment of CAS, WAS-root or WAS-stem$(0.01{\mu}g/ml)$. Taken together, inhibitory effect on mast cell-mediated allergic reactions of WAS-root is greater than those of WAS-stem but less than those of CAS.

  • Spirodela polyrhiza(L.) Schleid (Lemnaceae) have been used as a traditional drug in treating urticaria and itching. However, the exact role of Spirodela polyrhiza in allergic reaction has not been clarified yet. Type 1 hypersensitivity (immediate hypersensitivity), popularly known as allergy, is a major clinical problem in humans. It has been found that the histamine release from mast cells is an essential step in the pathological process of immediate hypersensitivity. In the present study, the effect of aqueous extract of Spirodela polyrhiza (AESP) on immediate hypersensitivity was investigated. AESP inhibited the antigen-induced passive cutaneous anaphylaxis (PCA). AESP in vitro exhibited a dose-dependent inhibition of degranulation in RPMC stimulated by compound 48/80. AESP also suppressed the morphological changes and the increase of intracellular free calcium level induced by compound 48/80. These results suggest that inhibitory effect of AESP on immediate hypersensitivity may be mediated through the decrease of intracellular free calcium levels, and AESP importantly contributes to the treatment of anaphylaxis and may be useful for other allergic disease.

  • 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.

  • We investigated the effect of Perilla frutescens (PF) ethanol extract powder (PF-E30) on the local allergic reaction activated by anti-DNP IgE and the mast cell-mediated immediate-type allergic reactions induced by compound 48/80 in a mouse model. One gram of PF powder extracted with 30% ethanol at $80^{\circ}C$ contained 12.3 mg of rosmarinic acid. Oral administration of PF-E30 (0.1 to 0.5 mg/kg body weight) significantly reduced plasma histamine levels and inhibited histamine release from peritoneal mast cells in mice activated by compound 48/80 or anti-DNP IgE. Moreover PF-E30 dose-dependently inhibited the production of antigen-induced IgE. These results indicate that the PF ethanol extract inhibits mast cell-mediated immediate-type allergic reactions in vivo and in vitro.

  • 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.

  • Object : We investigated the effect of Gamiokyaek-tang(GOYT) on immediate type hypersensitivity. Methods : We investigated anti-dinitrophenyl(DNP) IgE-mediated passive cutaneous anaphylaxis(PCA) and acetic acid-induced vascular permeability in rodents. Also we measured MTT assay, ${\beta}-hexosminidase$ activity and IL-4 from RBL-2H3 and nitric oxide from Raw264.7. Results : GOYT inhibited passive cutaneous anaphylaxis and acetic acid-induced vascular permeability by oral administration. All the concentrations of GOYT from 0.1 to 5mg/ml didn't have an effect on cell viability and cytotoxicity. In RBL-2H3, ${\beta}-hexosminidase$ release and IL-4 production were significantly reduced by 1, 2 and 5mg/ml of GOYT. In Raw264.7, nitric oxide level was decreased by 5mg/ml of GOYT. Conclusion : These results indicate that GOYT have inhibition effects on immediate type hypersensitivity.

  • Hyaluronidase, an enzyme that breaks down hyaluronic acid, has long been used to increase the absorption of drugs into tissue and to reduce tissue damage in cases of extravasation of a drug. With the increasing popularity of hyaluronic acid filler, hyaluronidase has become an essential drug for the correction of complications and unsatisfactory results after filler injection. For this reason, when performing procedures using hyaluronic acid filler, a sufficient knowledge of hyaluronidase is required. In order for hyaluronidase to dissolve a hyaluronic acid filler, it must interact with its binding sites within the hyaluronic acid. The reaction of a filler to hyaluronidase depends on the hyaluronic acid concentration, the number of crosslinks, and the form of the filler. Hyaluronidase is rapidly degraded and deactivated in the body. Therefore, in order to dissolve a hyaluronic acid filler, a sufficient amount of hyaluronidase must be injected close to the filler. If the filler is placed subcutaneously, injection of hyaluronidase into the filler itself may help, but if the filler is placed within a blood vessel, it is sufficient to inject hyaluronidase in the vicinity of the vessel, instead of into the filler itself. Allergic reactions are a common side effect of hyaluronidase. Most allergic reactions to hyaluronidase are local, but systemic reactions may occur in infrequent cases. Since most allergic responses to hyaluronidase are immediate hypersensitivity reactions, skin tests are recommended before use. However, some patients experience delayed allergic reactions, which skin tests may not predict.
