摘要:目的研究凉血解毒丸抗炎、抗敏的作用。方法采用2,4-二硝基氟苯(Dinitrofluobenzene 简称DNFB)造成变应性接触性皮炎(Allergic contact dermatitis 简称ACD)动物模型和磷酸组胺致豚鼠瘙痒模型,探讨“凉血解毒丸”的抗Ⅳ型变态反应作用。结果与模型组比较,凉血解毒丸组能显著降低2,4-二硝基氟苯所致的小鼠耳廓肿胀度,能显著抑制炎症细胞浸润和提高小鼠血清IL-10水平,差异具有统计学意义(P<0.05),但是对IFN-γ的产生无明显的影响(P>0.05);凉血解毒丸能显著止痒和增加磷酸酸组胺所致豚鼠瘙痒的致痒阈,差异具有统计学意义(P<0.05)。结论凉血解毒丸对小鼠变态性接触性皮炎有效,促进抗炎因子IL-10 的产生和表达可能是其治疗机制之一,具有抗炎、抗敏的作用,无明显毒副作用。

【Abstract】Objective: To study the anti-inflammatory and anti-allergic effects of Liangxue Jiedu Pill. Methods: 2, 4-dinitrofluobenzene (DNFB) was used to induce model guinea pig pruritus with allergic contact dermatitis (ACD) to study the anti-type Ⅳ allergic effect of Liangxue Jiedu Pill. Results: Compared with the model group, Liangxue Jiedu Pill group could significantly reduce the ear swelling of mice induced by 2,4-dinitrofluorobenzene, inhibit the infiltration of inflammatory cells and increase serum IL-10 level, and the difference was statistically significant (P<0.05), but there was no significant effect on the production of IFN-γ (P>0.05). Liangxue Jiedu Pill could significantly prevent itching and increase the itching threshold of histidine-induced guinea pig pruritus, and the difference was statistically significant (P<0.05). Conclusion: Liangxue Jiedu Pill is effective in mice with allergic contact dermatitis and can promote the production and expression of anti-inflammatory factor IL-10. It is one of its therapeutic mechanisms, anti-inflammatory and anti-allergic effect and no obvious side effects.

涼血解毒丸是在本院全国第三批名老中医学术经验继承工作指导老师、云南省名老中医刘复兴教授自创的皮内2号方—荆芩汤的基础上研发的中成药制剂(批号:滇药制字〈Z〉20082567A号,由云南省中医医院制剂中心生产)。该方主要由荆芥、黄芩、生地黄、牡丹皮、赤芍等药物组成,具有清热解毒、凉血止痒之功,临床主要用于治疗中医辨证属血热内蕴型的各类皮炎、湿疹及荨麻疹、药疹等多种变态反应性皮肤病[1][2]。凉血解毒丸具有明显抗炎、抗敏止痒的作用,且无明显毒副作用,然而其抗炎、抗敏的作用机理,如何延缓或控制变态反应性皮肤病的发生、发展,通过何种途径发挥作用,都尚不明确。本文通过建立2,4-二硝基氟苯(DNFB)所致的小鼠耳廓肿胀模型,观察凉血解毒丸对变应性接触性皮炎小鼠炎症细胞的抑制及对IL-10和IFN-γ表达的影响[2],通过磷酸组胺致豚鼠瘙痒模型观察其抗敏止痒的作用。……
