The saline water was used as a blank control, and 1% hydrochloric acid of methamphetamine Massachusetts was used as the negative control. Compared with normal saline control, the relative percentage of the lasting time of ciliary movement treated with Chinese medicine Xingbi was 94.1%. There was no remarkable pathological change in the tissue slice of nasal mucosa, and no stimulation on nasal mucous membrane was observed. So these data suggest that nasal thermosensible gel of Chinese medicine Xingbi is of high safety. It has no damage to the mucosa of toads and rats and can be used for intranasal administration.展开更多
目的:观察醒鼻凝胶剂对变应性鼻炎(AR)豚鼠鼻黏膜组织中核转录因子-κB(NF-κB)和血清中白介素-5(IL-5)、粒细胞-巨噬细胞集落刺激因子(GM-CSF)、趋化因子CCL-1表达的影响,从而探讨醒鼻凝胶剂治疗AR的可能机制。方法:健康豚鼠60只随机分...目的:观察醒鼻凝胶剂对变应性鼻炎(AR)豚鼠鼻黏膜组织中核转录因子-κB(NF-κB)和血清中白介素-5(IL-5)、粒细胞-巨噬细胞集落刺激因子(GM-CSF)、趋化因子CCL-1表达的影响,从而探讨醒鼻凝胶剂治疗AR的可能机制。方法:健康豚鼠60只随机分为6组:正常对照组,模型组,布地奈德组,醒鼻凝胶剂高、中、低剂量组。除正常对照组外,其他各组均以卵清蛋白加氢氧化铝腹腔注射制备AR豚鼠模型,于造模第16天开始给药,2次/d,连续给药11d后,ELISA法测定各组豚鼠血清中IL-5、GM-CSF、CCL-1的含量,RT-PCR、免疫组化法分别检测各组豚鼠鼻黏膜组织中NF-κB m RNA和NF-κB p65蛋白的表达。结果:模型组鼻黏膜组织中NF-κB m RNA和NF-κB p65蛋白的表达及血清中IL-5、GM-CSF、CCL-1的含量均明显高于正常对照组(P<0.01),且NF-κB p65的激活与IL-5、GM-CSF、CCL-1的表达呈显著正相关。AR模型豚鼠滴鼻给予高剂量醒鼻凝胶剂后鼻黏膜组织中NF-κB m RNA和NF-κB p65蛋白的表达明显减少(P<0.01),血清中IL-5、GM-CSF、CCL-1的含量均明显降低(P<0.01)。结论:醒鼻凝胶剂可能通过抑制NF-κB的活化与核移位,减弱了IL-5、GM-CSF、CCL-1的表达,从而减轻鼻道的炎性反应达到治疗作用。展开更多
