摘要 为探讨中药祛风清肺口服液治疗“风热喉痒咳嗽”的免疫学机理,用天花粉致敏大白鼠,分别观察各组致敏大鼠抗血清对正常大鼠皮肤被动过敏反应(PCA)的影响、模型组大鼠抗血清对各组大鼠(包括给药组与对照组)皮肤PCA的影响以及祛风清肺口服液对大鼠腹腔肥大细胞间接释放组织胺的影响。结果显示:皮内注射祛风清肺口服液低、高剂量组大鼠抗血清的大鼠皮肤皮片浸液的吸光度值比模型组降低(P<0.01或P<0.001);注射模型组大鼠抗血清后,祛风清肺口服液低、高剂量组大鼠背部皮肤注射点皮片浸液光密度值比正常组降低(P<0.05);祛风清肺口服液能抑制致敏大鼠腹腔肥大细胞释放组胺,与正常对照组相比,差异有显著性(P<0.01)。结果表明祛风清肺口服液有抗Ⅰ型变态反应作用,为其治疗“风热喉痒咳嗽”提供了一定的免疫药理学基础。 The immunological mechanism of Qufeng Qingfei Oral Liquid(QQOL) in treating wind-heat type throat itching and cough was explored in this study. Five types of anti-serum (AS) of rats,i.e, AS of normal rats, AS of rats administrated with high and low dosages of QQOL(AS1,AS2),AS of model rats (AS3) and AS of rats administrated with cyclophosphamide, were prepared first.The effects of QQOL on passive cutaneous anaphylaxis (PCA) of normal rats injected with various types of AS, on PCA of rats in the treatment and control groups injected with AS3 and on the indirect release of histamine of celiac mastocyte were observed.The results showed that:(1) the absorption value of skin graft infusion of normal rats injected with AS1 and AS2 was lowered markedly(P< 0.01 or P< 0.001 ) as compared with that of rats injected with AS3;(2) After injection of AS3,the absorption value of rats in the treatment groups (with high and low dosages of QQOL respectively) was also lowered markedly (P< 0.05 ) as compared with that in the normal group;(3)Indirect release of histamine of celiac mastocyte was inhibited in rats sensitized by Radix Trichosanthis (P< 0.01 ) as compared with that in the control group. It is suggested that QQOL possesses an antagonistic effect on Type I allergy and this will supply a certain immunopharmacological basis for the treatment of wind-heat type throat itching and cough.
