  • Basophils and mast cells play an important role in $Fc{\varepsilon}RI-mediated$ allergic reaction as effector cells. We studied the effects of Acanthopanax chiisanensis on $Fc{\varepsilon}RI\;{\alpha}$ chain expression in human basophilic KU812F cells. Ethanol extracts from root and stem of A. chiisanensis were tested for inhibitory effects of $Fc{\varepsilon}RI\;{\alpha}$ chain expression. The cell surface $Fc{\varepsilon}RI\;{\alpha}$ chain expression was examined by flow cytometric analysis. All of the extracts of A. chiisanensis reduced the cell surface $Fc{\varepsilon}RI\;{\alpha}$ chain expression. Furthermore, A. chiisanensis extracts caused a decrease in the level of $Fc{\varepsilon}RI\;{\alpha}$ chain mRNA level and $Fc{\varepsilon}RI-mediated$ histamine release. These results suggest that root and stem extracts of A. chiisanensis play an important role in anti-allergic activity via down-regulation of $Fc{\varepsilon}RI\;{\alpha}$ chain expression and decrease in release of inflammatory mediator such as histamine.

  • This study was conducted to investigate the effect of beverage (beverage HC and beverage PG) using herbs on antimicrobial activity, proliferation of hepatic cancer cell (Hep3B) lines and sarcoma 180 (S-180) and antiallergy, respectively. Beverage PG showed higher antimicrobial activity than beverage HC against Staphylococcus aureus and Pseudomonas aeruginosa. Beverage HC and PG showed the tumor suppressive effect in mice injected with S-180 cells. The growth-inhibitoy ratio against tumor cells were $66\%\;for\;10\%$ beverage HC, $61\%\;for\;10\%$ beverage PG. In an anti-cancer test using Hep3B cells, beverage PG showed higher anti-proliferating effect than beverage HC. Beverage PG showed growth-inhibitory effect of $69.2\%\;at\;100\%$ beverage PG. Beverage PG inhibited histamine release from rat peritoneal mast cells (RPMC) activated by compound 48/80. In conclusion, these results suggest that beverage using herbs have an antimicrobial activity, anti-proliferating effect against Hep3B cell and S-180 tumor and will be beneficial in treatment of allergic reaction.

  • This study was conducted to investigate the anticancer (in vitro) and antiallergy effects of rice bran extracts. In an anticancer test using Hep3B cells and HeLa cells, water and 60% ethanol extracts of rice bran inhibited the growth of Hep3B and HeLa cell lines and morphological changes were also observed. In Hep3B cell lines, water extract of rice bran showed a higer antiproliferating effect than 60% ethanol extract. The growth-inhibitory effect against HeLa cells were 30.9% for $1,000{\mu}g/mL$, 88.8% for $3,000{\mu}g/mL$ rice bran water extract. The expressions of $Fc{\varepsilon}RI$ mRNA and c-kit in HMC-1 (human mast cell) were decreased by 60% ethanol treatment but tryptase mRNA was not changed. The extracts of rice bran inhibited histamine release from RPMC (rat peritoneal mast cell) activated by compound 48/80. Rice bran water extract showed inhibitory effect of 87% at $0.01{\mu}g/mL$ concentration and 60% ethanol extract inhibited the release of histamine by 86% at $100{\mu}g/mL$ concentration.

  • The measurement of histamine is to determine the degree of allergy because the allergic reaction can lead to the release of histamine. In general, the antigen-antibody reaction was quantified by measuring absorbance using a microplate reader. In this study, we compare the method using a general antigen-antibody reaction and the method using a high performance liquid chromatography mass spectrometer (HPLC-MS) of chemical analysis in the measurement of histamine secretion. The cell line used was RBL-2H3, an allergic reaction was induced by stimulation with C48/80 (compound 48/80). Allergy-induced cells degranulation rate was confirmed by measurement of ${\beta}$-hexosaminidase and cytotoxicity was performed for the validity of the experiment. The quantitative determination of histamine showed a significant difference, since the quantitative limit of the measurement by the antigen-antibody reaction was 10.257 ppm while the quantitative limit of the measurement by HPLC-MS was 0.020 ppm. Measurement of histamine in allergic activity and anti-allergy tests showed that the HPLC-MS analysis rather than the analysis of the antigen-antibody reaction is a more precise and accurate test.

  • Two Antihistamines, terfenadine and astemizole have been withdrawn from major markets for the reason that these durgs have been reported to induce QT interval prolongation associated with the onset of Torsades do Pointes (TdP), resulting in a life-threatening ventricular arrhythmia. In this study, we investigated effects of diphenhydramine on electrocardiograms and hemodynamic parameters in conscious telemetered dogs. We validated and defined the sensitivity of the test system by monitoring basal parameters and using positive control substance, terfenadine. Single administration effects were tested during 24 hours for each test drug at dose 1 mg/kg, 10 mg/kg, 30 mg/kg, 100 mg/kg. We monitored QT, QTc, heart rate, blood pressure and body temperature after administering test drugs. In conscious telemetered dogs, diphenhydramine significantly prolonged $QT\;(6.8\%\;of\;basal)\;and\;QTc\;(7.8\%\;of\;basal)$ at 100 mg/kg. Other parameters were not affected significantly. These findings suggest that antihistamines could induce important clinical relevance for patients taking excessive dosages of conventional antihistamines and those at risk of developing cardiac arrhythmias. Future studies that include other antihistamines and other classes will be necessary to predict the torsadogenic risk of drugs in humans.

  • 소아천식은 기도의 만성 염증 및 과민반응을 특징으로 나타내고 있어 염증을 일으키거나 알레르기 반응을 일으키는 물질로부터 차단하는 방법이 효과적임을 현대의학에서 이미 밝히고 있다. 한의학에서는 천증(喘證)에 본디 뿌리 깊은 근원(천유숙근(喘有夙根))이 있다고 간주하여 허약한 체질은 내적인 요인이고, 풍한침습(風寒侵襲)은 유발요인이며, 담음복폐(痰飮伏肺)와 신기휴허(腎氣虧虛)는 재발의 근본이라고 하였다. 본 연구에서는 소아 천식에 구마황(灸麻黃), 은행(銀杏), 건강(乾薑), 오미자(五味子), 백전(白前), 구백부(灸百部), 소자(蘇子) 등을 사용하였고, 경우에 따라 황기(黃?) 혹은 선령비(仙靈脾)를 추가하여 正氣(正氣)를 강화시키는 목적으로 사용하였다. 약리학적 연구에 따르면 마황과 건강, 오미자 등은 모두 기도의 염증세포 침윤(浸潤)를 억제하고 항알레르기 효과가 있으며, 건강과 오미자는 또한 히스타민에 대한 길항효과(拮抗效果)도 있는 것으로 알려져 있다. 은행 추출물은 혈소판 활성화 수용체에 대한 길항작용을 갖고 있으므로 이러한 물질들로 인한 기관지의 경련을 방지하여 천식증상을 왕화시킨다. 구백부(灸百部)는 지해(止咳)효과가 뛰어나다. 소아천식에 대한 치료는 표본동치(標本同治)의 원칙을 지키며, 증상이 완화된 단계에서도 중약 투여를 1-2개월 지속시키는 것이 중요하다. 소아에게 있어서 천식증상이 완화된 후 어혈(瘀血) 상태가 성인에 비해 심하지는 않지만, "구병필어(久病必瘀)"의 결과에 유의할 필요가 있다. 천식이 장기간 지속되면 필히 혈액순환 장애가 수반되므로 천궁(川芎)이나 단삼(丹蔘) 등의 활혈제(活血劑)를 가미하여 사용하면 효과를 높일 수 있다. 결론적으로 소아의 천식은 항염증, 평천(平喘), 화담(火痰), 지해(止咳)와 더불어 보신익기화어(補腎益氣化瘀)의 약물을 병행하여 사용하는 것이 바람직하며, 단순한 중약 투여는 일부 양약에 의한 소아성장에 미치는 영향을 피할 수 있어 더 많은 임상연구가 이어져야 한다.

  • The muscarinic antagonist l-[benzilic-4,4'-$^3H$]quinuclidinyl benzilate([$^3H$]QNB) bound to a single class of muscarinic receptor with high affinity in guinea pig ileal membranes. The $K_{D}$ and B$_{max}$ values for [$^3H$]QNB calculated from analysis of saturation isotherms were 54 pM and 156fmol/mg, respectively. H$_{1}$-blockers inhibited [$^3H$]QNB binding to ileal membranes with $K_{i}$ values ranged from 0.008 $\mu{M}$ to 1.6 $\mu{M}$. The pseudo-Hill coefficients of H$_{1}$-blockers for inhibition of [$^3H$]QNB binding to the ileal membranes were close to unit. The $K_{i}$ values for H$_{1}$-blockers were similar to the $K_{M}$ values calculated by Schild plot of functional data obtained from inhibition of the carbachol-induced contraction in guinea-pig ileum, suggesting that binding of H$_{1}$-blockers vs [$^3H$]QNB in ileal membranes represents an interaction with a receptor of physiological relevance. The $K_{H}$ values of H$_{1}$-blockers for H$_{1}$-receptor estimated from inhibition of the histamine-induced contraction were the range of 0.15 nM to 56.5 nM. The $K_{M}$/K$_{H}$ ratio of H$_{1}$-blockers varied over a wide range of 3 to 2300. Thus, the antihistaminic potencies of H$_{1}$-blockers do not correlate with their antimuscarinic potencies, which suggest that antihistamines have different antimuscarinic potencies in therapeutic blood levels causing similar antiallergic effect. Among 13 traditional antihistaminics examined in this study, drug having the highest and the lowest $K_{M}$/K$_{H}$ ratio is triprolidine and diphenidol, respectively. The present results demonstrate that the antimuscarinic property of antihistamines is not necessary for their antiallergic effect, and data on the affinity of antihistamines for muscarinic and H$_{1}$-receptors can be an important parameter in the selection and evaluation of these drugs.
