盐酸奥芬米洛对二硝基氟苯诱导小鼠迟发型变态反应的影响

[目的]观察盐酸奥芬米洛对小鼠迟发型变态反应的影响。[方法]取体重为18~22g的ICR小鼠120只,雌雄各半,按体重随机分6组,即空白对照组、模型对照组、盐酸奥芬米洛高(10·0mg/kg)、中(5·0mg/kg)、低(2·5mg/kg)剂量组和阳性对照(CsA15mg/kg)组,每组20只,各给药组分别给予相应浓度的相应药物,空白与模型对照组给予蒸馏水10ml/kg,每日1次,连续给药1周后,除空白对照组外,每鼠腹部用1%DNFB溶液均匀涂抹进行致敏,致敏后第5天,将1%DNFB溶液均匀涂抹于小鼠右耳进行攻击,空白对照组同样涂耳但未致敏,攻击后24h,测定右耳的肿胀度和小鼠的脾指数和胸腺指数。[结果]不同剂量的盐酸奥芬米洛能不同程度地降低DNFB致敏ICR小鼠耳廓肿胀度、降低脾脏系数和胸腺指数,[结论]盐酸奥芬米洛可抑制DNFB诱导小鼠迟发型变态反应(DTH),具有抑制小鼠的特异性细胞免疫功能的作用。

Effect of Oxfenmino Hydrochloric Acid on Delayed Allergic Reaction in Mouse Induced by Dinitrofluorobenzene

[Objective]To determine the effect of Oxfenmino hydrochloric acid on delayed allergic reaction in mouse. [ Method ] 120 ICR mice weighing 18~22g, half female and half male, were randomly and averagely divided into 6 groups according to weight:control group and model group (treated with distilled water at a dosage of 10ml/kg), three Oxfenmino hydrochloric acid groups (treated with Oxfenmino hydrochloric acid at a dosage of 10.0mg/kg, 5.0mg/kg and 2.5mg/kg respectively) and positive drug group (treated with CsA at a dosage of 15mg/kg); they were orally administered one time every day. After a continuous week of administration, all the groups were smeared evenly with 1%DNFB solution on the abdomen for allergy except the control group. Five days after allergy, 1%DNFB solution was smeared to right ear of all mice to stimulate the allergic reaction except that the control group was smeared with non-allergenic substance. 24 hours after attack, the auricle swelling, spleen index and thymus index in right mouse were determined. [ Result] Different dosages of Oxfenmino hydrochloric acid benefited to reduce auricle swelling, spleen index and thymus index in mouse with allergic reaction induced by DNFB at different degree. [ Conclusion] Oxfenmino hydrochloric acid can inhibit the delayed allergic reaction in mouse induced by DNFB and depress the ability of specific cell-mediated immunity.
