  • Type I allergic reaction and it's related clinical manifestations are known to occur by the effects of various chemical mediators. These chemical mediators are released from circulating basophils and tissue mast cells, which become 'sensitized' through the binding of antigens and antibodies of the IgE type to their cell surface receptors. Efforts to elucidate the mechanism of the release of these mediators, especially that of histamine, have been persued for years. The mechanism is not yet clarified at the present time. Recent reports of hyaluronidase, an enzyme known to be involved in the tissue inflammatory process, as possible participant in type I allergic reaction, initiated this study. Relationships between the hyaluronidase activity and histamine release from the sensitized rat peritoneal mast cells were investigated. Also anti-allergic agents, tranilast and disodium cromoglycate, along with known histamine releasers, morphine and compound 48/80, were used to observe the inhibitory and stimulatory effects of these substances on the hyaluronidase activity as well as histamine release from the rat mast cells. The results obtained are summarized as follows: 1) Hyaluronidase activity and histamine release from sensitiaed rat peritoneal mast cells started to increase on the 4th day of postsensitization. Hyaluronidase activity reached it's peak value on the 7th day of postsensitization and that of histamine release on the 14th day of postsensitization. 2) Hyaluronidase activity and histamine release from sensitized rat peritoneal mast cells, pre-treated with tranilast revealed significant decrease in comparison with those of non-treated cells. 3) Hyaluronidase activity and histamine release from sensitized rat peritoneal mast cells, pre-treated with tranilast, followed by morphine injection, revealed significant increase in comparison with those of tranilast treated cells. 4) In vitro study of hyaluronidase activity and histamine release from un-sensitized rat peritoneal mast cells, using morphine and compound 48/80 as activators, revealed significant increase compared to those of non-activator used cells. 5) In vitro study of hyaluronidase activity and histamine release from un-sensitized rat peritoneal mast cells, pre-treated with tranilast and disodium cromoglycate, using confound 48/80 and morphine as activators revealed significant decrease in comparison with those of tranilast and disodium cromoglycate treated cells. From above results, participation of enzyme hyaluronidase in the process of histamine release from sensitized rat pertioneal mast cells, could be suggested. It was also quite evident that the clinically used anti-allergic agents, tranilast and disodium cromoglycate, have significant inhibitory function on the hyaluronidase activity and histamine release from sensitized rat peritoneal mast cells, while morphine significantly increased the hyaluronidase activity and histamine release from sensitized rat peritoneal mast cells.

  • The effect of WK101 on compound 48/80-induced anaphylaxis was studied in rat. WK101 was found to exhibit a inhibitory activity on the compound 48/80-induced anaphylaxis. WK101 also inhibited the serum histamine release induced in anaphylaxis by compound 48/80. The effect of WK101 on the histamine release from rat peritoneal mast cells was studied. WK101 ($10^{3}-1mg/ml$) inhibited the histamine release induced by compound 48/80($5{\;}\mu\textrm{g}/ml$) in rat peritoneal mast cells. To clarify the mechanism of these inhibitons, we investigated the effects of WK101 on cAMP and intracellular calcium content of rat peritoneal mast cell. The content of cAMP in mast cells, when WK101 was added, was increased transiently, and was significantly increased more 53 fold at 10 sec than that of basal cells. Moreover, WK101 inhibited intracellular calcium release induced by compoound 48/80. This results suggest that WK101 may be useful for the prevention and treatment of allergy-related disease.

  • We studied the effects of sulfasalazine(SSZ) on anaphylaxis. SSZ was found to exhibit a inhibitory activity on the compound 48/80-induced anaphylaxis. SSZ also inhibited local a naphylaxis activated by anti-dinitrophenyl(DNP) IgE. Moreover, SSZ dose-dependently inhibited histamine ralease in rat peritoneal mast cells activated by compound 48/80 or anti DNP IgE. We investigated the effects of SSZ on cAMP of rat peritoneal mast cell. The level of cAMP in rat peritoneal mast cells, when SSZ was added, transiently and significantly increased approximately 16-fold compared with that of basal cells. These results suggest that the antianaphylactic action of SSZ may be associated with an increase in the intracellular cAMP content of the mast cells as the result of an inhibition of the cAMP phosphodiesterase.

  • We investigated the effect of aqueous extract of Cichorium intybus (CIAE) on mast cell-mediated immediate type allergic reactions. CIAE dose-dependently inhibited systemic anaphylactic reaction induced by compound 48/80 in mice. Especially, CIAE inhibited compound 48/80-induced anaphylactic reaction 100% with the dose of 1000 mg/kg. CIAE 1000 mg/kg also significantly inhibited local anaphylactic reaction activated by anti-dinitrophenyl (DNP) IgE. When mice were pretreated with CIAE at a concentration ranging from 0.1 to 1000 mg/kg, the plasma histamine levels were reduced in a dose-dependent manner. CIAE (1 to 1000 g/ml) dose-dependently inhibited histamine release from the rat peritoneal mast cells (RPMC) activated by compound 48/80 or anti-DNP IgE. These results indicate that CIAE inhibits mast cell-mediated immediate-type allergic reactions.

  • This report describes an inhibitory effect of Tongku-tang(TKT) on mast cell-mediated immediate-type allergic reactions. TKT is an Oriental herbal prescription, which has been successfully applied for the treatment of allergic disorders, mainly skin anaphylactic diseases in eastern medicine. TKT has concentration-dependently inhibited the ear swelling response induced by intradermal injection of non-specific mast cell degranulator compound 48/80 in mice. TKT also inhibited mast cell-dependent passive cutaneous anaphylaxis activated by dinitrophenyl (DNP)-IgE antibody in rats. I studied the effect of TKT on the histamine and β-hexosaminase release from the rat peritoneal mast cells by compound 48/80. TKT did not inhibit significantly the histamine and β-hexosaminase release from the rat peritoneal mast cells by compound 48/80. However, TKT inhibited both TNF-α and IL-1β secretion induced by phorbol 12-myristate 13-acetate and A23187 respectively. These results provide evidence that TKT may be beneficial in the treatment of immediate-type allergic reaction.

  • Recombinant murine stem cell factor (rmSCF) or recombinant murine nerve growth factor (rmNGF) induced the morphological change of large numbers of rat peritoneal mast cells (RPMC). We investigated the role of phosphatidylinositol $3^{l}-kinase$ (PI3-kinase) in receptors-mediated morphological change in RPMC. Exposure of RPMC to PI3-kinase inhibitor, wortmannin, before the addition of rmSCF and rmNGF antagonized those factors-induced morphological change. These results suggest that the PI3-kinase is involved in the signal transduction pathway responsible for morphological change following stimulation of rmSCF and rmNGF and that wortmannin blocks these responses.

  • Sabaiksan has been prescribed to treat various allergic diseases in herbal medicine which were induced by various vasoactive amine released from the mast cells. The constituents of Sabaiksan are Mori Cortex Radices(MCR), Lycii Cortex Radicis(LCR) and Glycyrrhizae Radix(GR). Recently, simple models of compound 48/80 induced anaphylactic shock and cutaneous reaction in vivo were developed to test various agents employed in the field of allergy and toxicology research. The purpose of this study is to evaluate the effects of Sabaiksan on compound 48/80 induced anaphylactic stock, cutaneous reaction and mesenteric mast cell degranulation rate in ICR mice, and on compound 48/80 induced peritoneal mast cell degranulation and histamine release in vitro. Groups of ICR mice were intraperitoneally pretreated with $100{\mu}{\ell}$ of saline, $MCR(2g/m{\ell}),\;LCR(2g/m{\ell}),\;GR(g/m{\ell})$ or Sabaiksan itself(MCR+LCR+GR) at 24, 12 and 1 hour before compound 48/80 solution ($10{\mu}{\ell}/gm$ B. W) were peritoneally given into them, and then mortality within 72 hours after the compound 48/80 injection, and mesenteric mast cell degranulation rate at 15 minutes after compound 48/80 injection were calculated. In vitro experiment, $400{\mu}{\ell}$ of rat peritoneal mast cell suspension$(10^6cell/m{\ell})$ were pretreated with $50{\mu}{\ell}$ of saline, $MCR(2g/m{\ell}),\;LCR(2g/m{\ell}),\;GR(g/m{\ell})$ or Sabaiksan itself at room temperature for 30 minutes, and then $50{\mu}{\ell}$ of compound 48/80 solution $(100{\mu}g/m{\ell})$ were added into it. 30 minutes after the addition of compound 48/80 solution, histamine release assay in the supernatant of peritoneal mast cell suspension were performed employing radioisotope enzymatic assay and morphologic changes of mast cells in each regular time point were photographed. Compared with controls, compound 48/80 induced anaphylactic shock was significantly inhibited by MCR and GR pretreatment into the ICR mice. Significant inhibition of compound 48/80 induced cutaneous reaction, mesenteric mast cell degranulation rate in vivo and histamine release from the rat peritoneal mast cells in vitro was observed only in MCR pretreated group. From the above results, it is suggested that MCR component of Sabaiksan may playa key role to suppress mast cell function since it has been applied to various allergic diseases.

  • Twenty-four different natural food materials extracted with 80% methanol were used to investigate the inhibition of cell-mediated immediate type allergic reactions induced by compound 48/80 in rat peritoneal mast cells (RPMCs). Nine 80% methanol extracts screened at a concentration of $10\;{\mu}g/mL$ inhibited histamine release from RPMCs induced by compound 48/80. Of these, two materials (Ulmus parvifolia and Liriope platyphylla Wang et Tang) were extracted and fractionated into four different solvent types (chloroform, ethylacetate, butanol, and water), and the fractions with major anti-allergic effects were assessed. The chloroform fraction of U. parvifolia (UP) at $5\;{\mu}g/mL$ and the ethylacetate fraction of L. platyphylla Wang et Tang (LPWT) at $1\;{\mu}g/mL$ showed the greatest inhibition of histamine release induced by compound 48/80. The chloroform fraction of UP and the ethylacetate fraction of LPWT in combination showed a greater inhibition of histamine release than either fraction alone. The cAMP levels in RPMCs treated with UP and LPWT were significantly greater than in cells treated with compound 48/80 alone. Our studies suggest that extracts from UP and LPWT may alleviate immediate type hypersensitivity reactions through the increase of cAMP levels in the mast cells.

  • Background: Human seminal plasma (HSP)-induced hypersensitivity is one of the serious complications with sexual intercourse. The clinical manifestations of HSP-induced hypersensitivity may be related to the release of vasoactive mediators from mast cell induced by HSP. It has recently been reported that HSP modulates immune systems and induces mast cell degranulation and histamine release from rat peritoneal mast cells (RPMC). Ketotifen and disodium cromoglycate (DSCG), anti-asthmatic and anti-allergic drugs, have a role of mast cell stabilization and inhibit mast cell-induced leukocyte rolling and adhesion. But the inhibitory agents of HSP-induced mast cell activation are unknown. This study was performed to investigate the effects of DSCG and ketotifen on the HSP-induced mast cell activation. Methods: For this, influences of DSCG and ketotifen on the human seminal plasma-induced degranulation, histamine release and morphological changes of RPMC were observed. Results: The mast cell degranulation and histamine release of RPMC by HSP were induced in a dose-dependent fashion. The HSP-induced cytomorphological changes such as swelling, intracellular vacoules, and interrupted cell boundary were significantly inhibited by pretreatment with DSCG or ketotifen. DSCG and Ketotifen inhibited the HSP-induced degranulation and histamine release from RPMC. Conclusion: From the above results, it is suggested that DSCG and ketotifen have a inhibitory effect of the HSP-induced mast cell activation. DSCG and ketotifen may be used for treatment of HSP-induced hypersensitivity.
