使用小鼠接触性过敏反应实验系,研究了祛风败毒散对小鼠过敏反应的抑制作用及其机制。试验方法:选用6～8周龄的BALB/c雌性小鼠,每组5只。①过敏性接触皮炎:将0.5％DNFB-A/O(2,4-二硝基氟苯-丙酮橄榄油溶液)25μl涂抹于小鼠背部剃毛处(Day0)致敏;5日后(Day5)每只小鼠左耳廓涂抹0.2％DNFB-A/O20μl激发过敏反应,24小时后测得的耳廓厚度与激发前厚度 The mouse contact allergic reaction experiment system was used to study the inhibitory effect of Qufengbaidu Powder on mice’s allergic reaction and its mechanism. Test Method: 6-8 week old BALB/c female mice were used, 5 in each group. 1Allergic contact dermatitis: Apply 0.5μg of DNFB-A/O (2,4-dinitrofluorobenzene-acetone olive oil solution) to the mice’s back shaved area (Day 0) for sensitization; 5 days later (Day 5) 0.2% DNFB-A/O 20μl was applied to the left ear of each mouse to stimulate the allergic reaction, and the thickness of the auricle and pre-experimental thickness measured after 24 hours
