Cortex Mori, the root bark of mulbery tree has been used as an antiphlogistic, diuretic, and expectorant in herbal medicine. The purpose of this study is to evaluate chicken gamma globulin (CGG)-specific IgE-induced morphologic and functional changes in rat peritoneal mast cells (RPMC), and to determine whether Cortex Mori could inhibit the CGG-specific IgE-depeildent mast cell degranulation and histamine release from RPMC. Results are 1) the degranuration and histamine release from RPMC were not induced within 1 hour after addition of Cortex Mori alone, 2) the CGG and CGG-specific IgE-Induced degranulation from RPMC was observed within 10 minutes, 3) the histamine release from RPMC sensitised with CGG-specific IgE was induced by tile addition of CGG, 4) CGG-specific IgE-dependent degranulation rate in RPMC pretreated with Cortex Mori was significantly Inhibited, compared to that of control group without Cortex Mori pretreatment, and 5) the CGG-specific IgE-dependent histamine release from RPMC was significantly inhibited by pretreatment with Cortex Mori. These data suggest that Cortex Mori contains some substances with capabilities to inhibit CGG-specific IgE-dependent degranulation and histamine release from RPMC.

유색미 겨 추출물이 염증반응에 미치는 효과를 호중구 세포주 및 비만세포가 분비하는 염증매개물질인 histamine과 ${\beta}-hexosaminidase$의 분비 및 염증 cytokine 생성에 대한 억제활성을 측정하여 평가하였다. 호중구 세포주인 RBL-2H3 세포와 rat에서 분리 추출한 복강 비만세포(RPMC, peritoneal mast cell)를 이용하여 histamine과 ${\beta}-hexosaminidase$ 분비에 대한 억제활성을 조사한 결과, 일반미 겨 추출물은 RBL-2H3 세포에서 염증매개물질들의 분비량을 증가시킨 반면, 유색미 겨 추출물은 이들의 분비를 억제하였다(histamine 10.19% 억제, ${\beta}-hexosaminidase$ 110.03% 억제). RPMC에서는 유색미가 histamine과 ${\beta}-hexosaminidase$의 분비를 일반미보다 각각 8배와 3배나 높게 억제하는 것으로 나타났다. 염증관련 cytokine으로서 $IL-1{\beta},\;TNF-{\alpha}$ 및 IL-6의 발현을 RT-PCR로 측정한 결과, 유색미가 일반미 보다 $TNF-{\alpha},\;IL-1{\beta}$ 및 IL-6의 발현을 억제하는 효과가 우수하였다. ELISA를 이용하여 cytokine의 분비량을 측정한 실험에서도 유색미가 일반미보다 $TNF-{\alpha},\;IL-1{\beta}$ 및 IL-6의 분비를 효과적으로 억제하였다. 이상의 결과는 유색미가 염증반응의 원인 물질인 histamine과 ${\beta}-hexosaminidase$의 분비에 대한 억제효과 뿐 아니라, 염증 cytokine의 발현을 저해하는 효과도 일반미보다 우수하다는 사실을 보여주었다.

The effect of acteoside, a phenylpropanoid glycoside isolated from Clerodendron trichotomum Thunberg, on histamine and arachidonic acid release was investigated in RBL 2H3 cells. Histamine was dose-dependently released from RBL 2H3 cells by melittin, arachidonic acid and thapsigargin. In extracellular $Ca^{2+}-free$ solution, basal secretion of histamins increased by two fold. The response of histamine release to melittin and thapsigargin in $Ca^{2+}-free$ solution was significantly decreased, whereas the response to arachidonic acid was significantly increased as compared with those in normal solution. Acteoside inhibited histamine release induced by melittin, arachidonic acid and thapsigargin in a dose-dependent manner in the presence or absence of extracellular $Ca^{2+}$. However, the inhibitory activity of acteoside was more potent in normal solution than that in $Ca^{2+}-free$ solution. These data suggest that inhibitory mechanism of acteoside on histamine release may be related to extracellular $Ca^{2+}$. On the other hand, acteoside significantly inhibited arachidonic acid release and prostaglandin $E_2$ production Induced by $0.5\;{\mu}M$ melittin. It is possible that acteoside may be developed as an anti-inflammatory agent.

We previously reported that some components of ginsenosides decreased mediator releases evoked by the activation of mast cells with specific antigen-antibody reactions. This study aimed to assess the effects of ginsenosides ($Rb_2$, Re) on the mechanism of histamine release in the mast cell activation. We partially purified guinea pig lung mast cells by using enzyme digestion, the rough and the discontinuous percoll density gradient method. Mast cells were sensitized with $IgG_1$ and challenged with ovalbumin (OA). Histamine was assayed by fluorometric analyzer, leukotrienes by radioimmunoassay. Phospholipase D (PLD) activity was assessed more directly by the production of $[^3H]phosphatidylbutanol$ (PBut) which was produced by PLD-mediated transphosphatidylation in the presence of butanol. The amount of 1,2- diacylglycerol (DAG) were measured by the $[^3H]DAG$ labeled with $[^3H]palmitic$ acid or $[^3H]myristic$ acid. Pretreatment of $Rb_2$ ($300\;{\mu}g$) significantly decreased histamine release by 60%, but Re ($300\;{\mu}g$) increased histamine release by 34%. Leukotrienes release in $Rb_2$ was decreased by 40%, Re was not affected in the leukotrienes release during mast cell activations. An increasing PLD activity during mast cell activation was decreased by the dose-dependent manner in the pretreatment of $Rb_2$, but Re pretreatment facilitated the increased PLD activity during mast cell activation. The amount of DAG produced by phospholipase C (PLC) activity was decreased by $Rb_2$ pretreatment, but Re pretreatment was not affected. The amount of mass DAG was decreased by $Rb_2$ and Re pretreatment during mast cell activation. The data suggest that $Rb_2$ purified from Korean Red Ginseng Radix inhibits the DAG which is produced by the activation of mast cells with antigen-antibody reactions via both phosphatidylinositide-PLC and phosphatidylcholine-PLD systems, and then followed by the inhibition of histamine release. However, Re increases histamine release by stimulation of DAG production, which is mediated by phosphatidylcholine-PLD system rather than by phosphatidylinositide-PLC system, but inhibits the mass DAG production. Thus, it could be inferred that other mechanisms play a role in the increase of histamine release during mast cell activation.

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.

Allergy, meaning 'heightened reactivity' of a host on being exposed to an antigen, is an immediate reaction which included anaphylaxis following contact with an antigen. An anaphylatic reaction is caused by the release of pharmacological mediators, like histamine, from mast cells. The potential anti-allergic activities of 27 seaweed and 19 salt marsh extracts collected from the coast of Korea were tested against the inhibition of histamine release in rat peritoneal mast cells (RPMCs). Among them, three salt marsh plants (Persicaria lapathifolia, Ixeris tamagawaensis, and Salsola komarovil) significantly showed more than 75% of inhibition of the histamine release at a concentration of $100{\mu}g/mL$, and also three salt marsh (Messerschmidia sibirica, Rosa rugosa, and Portulaca oleraceae) and three seaweed (Colpomenia bullosa, Derbesia marina, and Sargassum thunbergil) extracts exhibited moderately inhibition effects when compared to the control.

The effect of glycyrrhetinic acid(18.betha.-glycyrrhetinic acid, GA) on histamine synthesis and release was investigated in cocultured mast cells with Swiss 3T3 fibroblasts. GA has strong dose dependent inhibitory activity for histamine synthesis and release in cocultured mast cells. GA(50 .mu.M) inhibited about 85% of histidine decarboxylase (HDC) activity. The appearance of cells staining positively with berberine sulface was also decreased in the presence of GA. It indicates that transdifferentiation of cultured mas cells (CMCs) was also inhibited.

Dendroaspis natriuretic peptide (DNP)는 최근에 green Mamba snake Dendroaspis angusticeps의 독(venom)에서 발견된 17개의 아미노산 disulfide링 구조를 포함하는 38개 아미노산 펩티드로 natriuretic peptide family와 그 구조가 비슷하다. Natriuretic peptide family는 사람과 흰쥐 비만세포로부터 히스타민을 유리시킨다고 알려져 있다. 그러나 DNP가 비만 세포로부터 히스타민을 유리 시키는 여부는 밝혀져 있지 않다. 본 연구는 DNP가 흰쥐 복강 비만세포로부터 히스타민을 유리시키는 여부와 함께 히스타민 유리기전을 구명하고자 실시되었다. 다양한 농도의 DNP를 흰쥐 복강 비만세포에 처리한 다음, 비만세포의 탈과립을 도립 광학현미경으로 관찰하였다. 히스타민 유리량은 방사효소법으로 측정하였고 세포내 칼슘 유입량과 cyclic GMP의 수준은 방사면역법으로 측정하였다. DNP는 흰쥐 복강 비만세포를 탈과립시켰고 농도가 증가함에 따라 비만세포로부터 히스타민 유리량이 증가되었다. 또한 DNP는 농도 증가에 비례하여 비만세포 안으로 세포밖의 칼슘을 유입시켰으며 세포안의 cyclic GMP의 수준을 증가시켰다. 이상의 결과로 미루어, DNP는 비만세포 안의 cyclic GMP와 칼슘의 농도를 증가시켜 비만세포로부터 히스타민을 유리시키는 것으로 생각된다.
