鼻舒滴丸抗过敏作用及机理分析

目的 :研究中药鼻舒滴丸 (BSDW)对 2 .4-二异氰酸甲苯酯 (TDI)和组织胺造型豚鼠的影响及其作用机理。方法 :采用 10%TDI橄榄油溶液为致敏剂造成豚鼠变应性鼻炎模型 ,观察BSDW对豚鼠变应性鼻炎模型鼻部症状、病理组织学及对血和鼻粘膜中组织胺含量及血清IgE含量的影响。采用组织胺造成豚鼠休克模型 ,观察BSDW对组织胺造型豚鼠的症状影响。结果 :BSDW可显著减轻变应性鼻炎模型豚鼠鼻粘膜病理改变 ,与造型对照组相比可使鼻粘膜柱状上皮和固有层腺体增生显著减轻 ,固有层嗜酸性细胞、嗜中性白细胞、单核细胞浸润明显减少 ,纤毛明显修复。还可明显降低变应性鼻炎模型豚鼠血清IgE的水平 ,减少血清及鼻粘膜中组胺的含量 ,可显著延长变应性鼻炎模型和组织胺造型豚鼠喘息和惊厥出现的时间 ,明显减少豚鼠哮喘的次数及延长组织胺造型豚鼠休克死亡时间。结论 :鼻舒滴丸有明显的抗过敏作用 ,其抗过敏作用的机理可能与其能降低血清IgE的含量、抑制全血和鼻粘膜中组织胺的释放密切相关。

Effect and Mechanism of Bishudiwan(BSDW) Against Allergy

Objective: To investigate the effect and mechanism of BSDW on the model of allergic rhinitis and the model of guinea pigs by histamine shocking in guinea pigs. Method: Using the model of allergic rhinitis in guinea pigs caused by 10%TDI, we observed the effect of BSDW on physiological and pathological symptoms of allergic rhinitis in guinea pigs, the effect of the levels of serum IgE and serum and nasal histamine. Using the model of guinea pigs by histamine shocking, we observed the effect of BSDW on physiological symptoms in guinea pigs. Result: BSDW significantly relieved the pathological symptoms of allergic rhinitis in guinea pigs, alleviated the hyperplasia of columnar epithelium, decreased the number of monocyte and eosinocyte compared with the model group. It also reduced the levels of serum IgE, and decreased the release of serum and nasal histamine. BSDW significantly prolonged the occurent time of gasping, eclampsia and death caused by shock,reduced the times of gasping in the model of guinea pigs by histamine shocking. Conclusion: BSDW has significant effect against allergy. The mechanism relates to its effects of decreasing the levels of serum IgE and inhibiting the release of serum and nasal histamine.
