Vascular thrombosis and ischemic necrosis still remain the most significant threats to the survival of free flaps. To date, neutrophils have been implicated in the pathogenesis of postischemic injury. Several studies have demonstrated that modulating the neutrophil response to ischemia-reperfusion injury can decrease the extent of the injury. In addition, some authors noticed that mast cell counts were also increased in flaps exposed to state of ischemia/reperfusion. So, we designed to evaluate the role of mast cells in ischemia/reperfusion by blocking histamine and to compare the effect of L-arginine, a nitric oxide precursor which is known to prevent neutrophil-mediated tissue injury. Epigastric island skin flaps were elevated in 30 rats and rendered ischemic. Thirty minutes prior to reperfusion, the rats were treated with intraperitoneal saline, diphenhydramine, cimetidine, and L-arginine. The necrosis rate of flap at 7 days, the number of neutrophils and mast cells at 20 hours were evaluated. In conclusion, histamine receptor blockers as well as L-arginine significantly decreased flap necrosis in a rat skin island ischemia-reperfusion flap model, but the protective effect was not significantly different in both agent groups.

We studied the effect of Rubus croceacanthus Leveille (RCL) on mast cell-mediated anaphylactic reactions. RCL inhibited compound 48/80-induced systemic anaphylactic shock. When RCL was given at concentrations ranging from 0.01 to 1 mg/$m\ell$, the histamine release from rat peritoneal mast cells induced by compound 48/80 was reduced in a dose-dependent manner. RCL also inhibited passive cutaneous anaphylaxis activated by anti-dinitrophenyl IgE. In addition, RCL inhibited phorbol 12-myristate 13-acetate and A23187-induced tumor necrosis factor-${\alpha}$ secretion from human mast cell line HMC-1 cells. These results indicate that RCL may possess a strong anti-anaphylactic activity.

We investigated the effect of aqueous extract of Gleditsia sinensis thorns (Leguminosae) (GSAE) on the mast cell-dependent anaphylaxis. GSAE (0.005 to 1 ${g}/kg$) dose-dependently inhibited systemic anaphylaxis induced by compound 48/80 in rats. GSAE (0.1 and 1 ${g}/kg$) also significantly inhibited local anaphylaxis activated by anti-DNP IgE. When GSAE was pretreated at the same concentrations with systemic anaphylaxis, the plasma histamine levels were reduced in a dose-dependent manner. GSAE (0.001 to 1 ${m}g/ml$) dose-dependently inhibited the histamine release from rat peritoneal mast cells (RPMC) activated by compound 48/80 or anti-DNP IgE. The level of cyclic AMP in RPMC, When GSAE (1 ${m}g/ml$) was added, transiently and significantly increased about fourfold compared with that of basal cells. Moreover, GSAE (0.01 and 0.1 ${m}g/ml$) had a significant inhibitory effect on anti-DNP IgE-induced tumor necrosis factor-$\alpha$ production from RPMC. These results suggest a possible use of GSAE in managing mast cell-dependent anaphylaxis.

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 current study evaluates the capacity of eugenol to regulate immediate allergic reaction by control of histamine release. Administrations of eugenol (1M/kg, i.p.) at 60 min b efore and 5, 10 min after the compound 48/80 treatment (8mg/kg, i.p.) were shown the mortality rates as 0, 44.4, and 77.8%, respectively. A 60 min before administered group revealed a significant inhibition of serum histamine release compared with those of 5 and 10 min after the compound 48/80 injection. Eugenol (6-48mM) was also showed a dose-dependent activity on the compound 48/80-induced histamine release from the highly purified population of Alcian Blue-positive peritonea] mast cells. These results indicate that in vitro treatment with exogenous eugenol inhibited the active response of mast cell populations and modulated its characteristics.

Samul-Tang (SMT) has been used for nourishing of the blood, hematopoiesis as a herbal medicine history. The purpose of this study is to find out anti-allergic inflammatory reaction of SMT. To clarify the mechanism, the effect of SMT on vascular permeability of rat cutaneous tissue and histamine and cytokines (IL-6, IL-8, TNF-${\alpha}$) release from mast cells were observed. The results are the pretreatment with SMT significantly decreased the compound 48/80-induced degranulation and histamine release from RPMC, SMT also inhibited the anti-DNP lgE-induced increment of vascular permeability of rat cutaneous tissue. SMT significantly reduced the PMA plus A23187-induced increment of expression of IL-6, IL-8, and TNF-${\alpha}$ in HMC-1 Cell. The Present study provide evidence that SMT inhibits mast cell-derived inflammatory allergic reactions by blocking histamine release and pro-inflammatory cytokine expression, and suggest the mechanisms of action. Furthermore, in vivo and in vitro anti-allergic effect of SMT suggests a possible therapeutic application of this agent in inflammatory allergic diseases.

Purpose: The purpose of this study was to investigate the role of mast cells and their product, histamine and leukotriene in ischemia-reperfusion injury. Methods: Forty Sprague-Dawley rats were divided into four groups. (Group I: Control group without ischemia, Group II: Normal saline with ischemia, Group III: Cimetidine with ischemia, Group IV: Zafirlukast with ischemia) Skin flap was elevated and ischemic insult was given by clamping the artery for 12 hours. Before reperfusion, the rats were treated with saline, cimetidine and zafirlukast. Flap survival was evaluated at 7 days. Neutrophil counts, mast cell counts were evaluated 24 hours after reperfusion. Results: Flap survival rate in the control group was 92.33%, whereas normal saline group had 37.34% survivals. Cimetidine and zafirlukast treated group showed significantly higher survival rates than normal saline group. The neutrophil and mast cell counts in cimetidine and zafirlukast treated group were significantly decreased than normal saline group. Cimetidine treated group showed higher survival rate and lower cell counts than zafirlukast treated group. Conclusion: The administration of cimetidine and zafirlukast can decrease neutrophils and mast cells caused by ischemia-reperfusion and increase flap survivals. It is suggests that antihistamine and leukotriene receptor antagonist have protective effect against ischemia-reperfusion injury to skin flap in rat.

Objectives : In this study, we investigated anti-allergic effect of Okbyeongpungsan-Hap-Changijasan (KOB01) in allergic rhinitis(AR) experimental animals and mast cells. Methods : The potential anti-allergic effect of KOB01 was investigated in a rat model of compound 48/80-induced systemic anaphylactic shock and a mouse of ovalbumin(OVA)-induced AR, and human mast cell line, HMC-1 culture. Each animals were divided into four groups: normal, control, KOB01-treated(100 and 200 mg/kg) and anti-histamine drug, dosodium cromoglycate (DSCG)-treated(50 mg/kg). Animals were orally treated with KOB01 and DSCG and intraperitoneally injected with compound 48/80($10\;{\mu}g/kg$) or sensitized with 0.1% OVA. The mortality and serum histamine levels were measured in compound 48/80-induced anaphylatic rats. The histological changes in nasal mucosa were investigated in OVA-induced AR mice. Also, mast cell degranulation was observed in compound 48/80-stimulated HMC-1 cells. Results : KOB01 increased mortality and significantly decreased serum histamine levels in compound 48/80-induced anaphylatic rats. The abnormal histological changes such as expansion of grandular cells and hypertrophy of epithelium in nasal mucosa of OVA-induced AR mice was improved by KOB01 treatment nearby a normal group. Therefore, KOB01 inhibited compound 48/80-induced degranulation in HMC-1 cells. Conclusions : These results indicate that KOB01 decrease allergic response through suppressing the mast cell activation in AR and suggest a potential role for KOB01 as a source of anti-allergic agents for use in allergic disorders including of AR.

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.

In the present investigation, we studied the effect of alcoholic extract of Moringa oleifera (M. oleifera) seed kernels on various experimental models of bronchial asthma. Significant (P < 0. 05) increase in preconvulsion time was observed due to pretreatment with M. oleifera when the guinea pigs were exposed to either acetylcholine (Ach) or histamine aerosol. This bronchodilating effect of M. oleifera was comparable to ketotifen fumarate. Spasmolytic effect of M. oleifera was also observed by dose dependent inhibition of ideal contractions induced by Ach, 5HT, histamine and $BaCl_2$. Alcoholic extract of M. oleifera produced significant dose dependent protection by egg albumin and compound 48/80 induced mast cell degranulation. Pretreatment with alcoholic extract of M. oleifera also decreased carrageenan induced rat paw edema, which was comparable to that of standard diclofenac sodium. Minimum inhibitory concentration for alcoholic extract of M. oleifera was low as compared to cold-water extract and hot water extract when antimicrobial activity was tested against various respiratory pathogens like Escherichia coli (E. coli), Staphylococus aureus (S. aureus) and pseudomonas aeruginosa (P. aeruginosa). Our data suggest that antiasthmatic activity of M. oleifera seed kernels may be due to its bronchodilator, anti-inflammatory, mast cell stabilization and antimicrobial activity.
